TE Connectivity 737431-2 D-Sub Backshell Equivalent & Substitute Parts

Part Overview

The TE Connectivity 737431-2 is a 15 Position Two Piece Backshell Connector in black, designed for D-Sub applications with a 180° cable exit angle. This component functions as an accessory backshell for AMPLIMITE series connectors, providing cable strain relief and mechanical protection in unshielded configurations.

The 737431-2 carries an Obsolete product status. Identification of equivalent and substitute components is necessary to support legacy system maintenance, repair, and continued field deployment where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 737431-2 is constrained by the following critical parameters:

Mandatory Matching Parameters:

• Series: AMPLIMITE
• Number of Positions: 15
• Compatible Shell Size: A
• Cable Exit Angle: 180°
• Accessory Type: Two Piece Backshell
• Primary Material: ABS Plastic
• Shielding Configuration: Unshielded

Compliance Parameters:

• RoHS Status: ROHS3 Compliant or equivalent
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99

The substitute part 174570-1 is identified as a Cable Clamp Kit for 15 Position AMPLIMITE connectors. This component shares the AMPLIMITE series designation and 15-position configuration with the main part. However, the substitute part is categorized as a cable clamp accessory rather than a backshell assembly, indicating a functional difference in application scope.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 737431-2 is classified as Obsolete, while the substitute part 174570-1 maintains Active product status. Active status indicates continued manufacturing support, availability, and compliance maintenance by TE Connectivity.

Compliance Alignment: Both components satisfy RoHS compliance requirements and carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and procurement purposes.

Functional Differentiation: The 737431-2 functions as a complete two-piece backshell assembly with integrated strain relief and mating hardware. The 174570-1 is specified as a cable clamp kit, representing a complementary but distinct accessory function within the AMPLIMITE connector ecosystem.

Selection between these components depends on the specific application requirement: backshell assembly functionality versus cable clamping functionality. Both components are compatible with 15-position AMPLIMITE connectors and share identical environmental and regulatory classifications.

Frequently Asked Questions (FAQ)

Q: Can the 174570-1 Cable Clamp Kit directly replace the 737431-2 Backshell?

A: No. The 737431-2 is a two-piece backshell assembly providing complete cable exit protection and strain relief. The 174570-1 is a cable clamp kit, which serves a different functional purpose. Direct substitution is not applicable unless the application requirement is specifically for cable clamping rather than backshell assembly.

Q: Are both parts compatible with the same connector sizes?

A: Both components are designated for 15-position AMPLIMITE series connectors. The 737431-2 explicitly supports Shell Size A and is compatible with 15pos and HD26pos D-Sub configurations. The 174570-1 is specified for 15-position AMPLIMITE connectors without detailed shell size documentation in the provided parameters.

Q: What is the significance of the Obsolete status for the 737431-2?

A: Obsolete status indicates that TE Connectivity has discontinued active manufacturing and support for this component. The 174570-1 maintains Active status, meaning it continues to receive manufacturing support and compliance updates. For new designs or long-term system support, Active components are preferred.

Q: Do both parts meet current RoHS requirements?

A: Yes. The 737431-2 is ROHS3 Compliant, and the 174570-1 is RoHS Compliant. Both components satisfy current regulatory requirements for hazardous substance restrictions.

Q: What is the cable exit angle for the 737431-2?

A: The 737431-2 features a 180° cable exit angle, indicating a straight-back cable routing configuration. This parameter is specific to the backshell assembly and is not applicable to the cable clamp kit.

Q: Are there any moisture sensitivity concerns with these components?

A: Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control handling during storage, transport, or assembly.
