955347N001 Heat Shrink Cable Boot for Wire and Cable Protection

ElecSuppliers Part Number GuideAug 28, 2026

When searching for 955347N001, it is easy to mistake the number for a conventional connector part because it appears in electronic component distribution databases alongside many interconnect products.

In fact, 955347N001 is a TE Connectivity part number corresponding to 202K132-3-0-CS7025, a heat shrink cable boot and end-cap product.

Its purpose is fundamentally different from that of an electrical connector. Instead of creating an electrical connection between two components, the part is used to provide mechanical protection and environmental protection around cable and wire terminations.

That distinction is the first thing buyers should understand when looking for this model.

What Is 955347N001 Used For?

955347N001 is associated with a TE Connectivity heat shrink cable boot and end-cap solution.

The basic idea behind a heat shrink boot is straightforward: the component is positioned around a cable, wire termination or related interface and then heated so that it contracts around the assembly.

The resulting structure can help protect the cable transition from mechanical stress and environmental exposure.

This makes a heat shrink boot particularly useful where a bare cable termination would otherwise be vulnerable.

955347N001 Is Also Known as 202K132-3-0-CS7025

One important point for procurement is that 955347N001 is an alternate or distributor-facing part number associated with TE Connectivity's 202K132-3-0-CS7025.

This means buyers searching for either number may encounter the same underlying product.

For sourcing, keeping both identifiers in the search can be useful:

955347N001

202K132-3-0-CS7025

However, the complete number should always be verified against the manufacturer's documentation before ordering.

This is especially important for heat shrink products because visually similar boots can have very different dimensions and material characteristics.

Why Cable Boots Matter in High Reliability Wiring

A cable termination is often mechanically weaker than the cable itself.

Without suitable strain relief and environmental protection, repeated bending or pulling can concentrate stress at the termination.

A heat shrink boot provides a transition between the cable and the termination area.

Instead of allowing the cable to bend sharply at one point, the boot can help create a more controlled transition.

This is one reason cable boots are widely used in demanding wiring assemblies.

Protection Is More Than Keeping Water Out

When people hear "heat shrink," they often think only about electrical insulation.

A cable boot can provide several forms of protection at the same time.

Depending on the product construction and application, the boot can contribute to:

Mechanical protection

Strain relief

Electrical insulation

Environmental sealing

Protection against contamination

Improved cable termination durability

The exact performance depends on the construction and installation conditions specified for the particular TE Connectivity product.

The Heat Shrink Process Is Part of the Installation

955347N001 should not be treated like a passive connector that is simply plugged into a PCB.

Installation involves positioning the heat shrink component correctly and applying controlled heat.

The installer needs to consider the cable diameter, termination geometry and heating process.

Uneven heating can result in incomplete recovery.

Excessive heating can potentially damage the cable assembly or surrounding materials.

For production environments, following the manufacturer's recommended installation procedure is therefore important.

Cable Diameter Is a Critical Selection Parameter

One of the biggest mistakes when purchasing heat shrink boots is selecting a part based only on its appearance.

The cable diameter and recovery characteristics need to match the intended assembly.

If the boot is too large, it may not provide the desired mechanical or environmental protection after shrinking.

If it is too small, installation may be impossible or may place excessive stress on the assembly.

For this reason, the dimensional information for 202K132-3-0-CS7025 / 955347N001 should be checked before a replacement is approved.

Why the 955347N001 Number Matters in Replacement Work

Heat shrink boots are particularly vulnerable to substitution errors.

A replacement may look almost identical but have a different recovered diameter, expanded diameter, length or material specification.

For a cable harness already qualified for a particular environment, changing those characteristics can affect the final assembly.

That makes the exact MPN valuable.

Rather than searching for a generic "heat shrink cable boot," buyers should start with 955347N001 and then verify the equivalent TE Connectivity designation.

Where This Type of Component Fits

Heat shrink cable boots are commonly relevant to demanding wire and cable assemblies.

Potential applications can include aerospace wiring, transportation equipment, industrial electronics, military and defense systems, communications equipment and other applications where cable termination protection is important.

The exact suitability of 955347N001 should always be determined from the manufacturer's specifications and the environmental requirements of the finished assembly.

It Is Not an Electrical Connector

This is an important distinction for anyone searching the model for the first time.

955347N001 does not function like a plug, socket or PCB connector.

Its role is associated with the physical protection of a cable or termination.

That means its performance should be evaluated through characteristics such as dimensions, recovery behavior, material, environmental resistance and installation requirements rather than contact count or connector pitch.

Understanding this difference immediately makes the search results for the model much easier to interpret.

Why TE Connectivity Identification Helps

TE Connectivity produces a very large range of interconnection and cable-management products.

The same general product category can contain many variations designed for different cable sizes and environments.

Identifying 955347N001 as the TE Connectivity 202K132-3-0-CS7025 product gives buyers a much more precise starting point than searching for a generic heat shrink boot.

It also helps prevent confusion with similarly shaped products from other manufacturers.

What to Check Before Ordering 955347N001

Before purchasing the part, confirm the complete part number and its corresponding TE Connectivity designation.

Then check the dimensions required for the cable assembly, the installation method and the environmental conditions in which the finished assembly will operate.

For replacement work, compare the original boot with the proposed component rather than assuming that a product from the same general heat shrink category will provide equivalent performance.

Supplier traceability is also worth considering for aerospace, industrial or other high-reliability applications.

Why 955347N001 Is a Useful Search Term

The value of 955347N001 is not in being a generic electronic component number.

It identifies a specific cable protection product that can be traced to the TE Connectivity 202K132-3-0-CS7025 designation.

For engineers, the model is relevant when designing or maintaining cable termination assemblies.

For purchasing teams, the exact number helps locate the correct product instead of comparing unrelated heat shrink boots.

ElecSuppliers can also provide a supplier discovery route for buyers searching specifically for 955347N001.

The key takeaway is simple: 955347N001 is a heat shrink cable boot and end-cap part number, so its selection should be based on cable protection requirements and the exact termination geometry rather than connector specifications.
