TE Connectivity AMP Connectors 647401-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 647401-9 is a 9-position rectangular connector receptacle housing designed for 0.156" (3.96mm) pitch applications. This component is classified as a free-hanging, in-line receptacle with crimp contact termination and locking ramp fastening. The part is currently active in production status and maintains full RoHS compliance with Moisture Sensitivity Level 1 (unlimited shelf life). Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity.

Engineering Selection Recommendations

All three parts—647401-9, 2132189-9, and 640250-9—are functionally equivalent rectangular connector receptacles within the TE Connectivity SL-156 series. Selection between these parts is based on availability and compliance requirements:

647401-9: Active production status with RoHS compliance. Current inventory: 746 pieces.

2132189-9: Active production status with ROHS3 compliance (enhanced environmental standard). Current inventory: 711 pieces.

640250-9: Active production status with RoHS compliance. Current inventory: 1993 pieces (highest availability).

All parts maintain identical electrical and mechanical specifications, operating temperature ranges, and moisture sensitivity classifications. Selection should prioritize part availability and specific compliance certifications required by the application or regulatory framework.

Frequently Asked Questions (FAQ)

Q: Can 2132189-9 and 640250-9 be used interchangeably with 647401-9?

A: Yes. All three parts share identical specifications for connector type, contact configuration, pitch, mounting method, termination type, and operating parameters. They are direct functional equivalents within the SL-156 series.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents an enhanced version of the RoHS directive with additional environmental restrictions. Part 2132189-9 carries ROHS3 certification, while 647401-9 and 640250-9 carry standard RoHS certification. Selection depends on regulatory requirements for the end application.

Q: Are contacts included with these connector housings?

A: No. All three parts are connector housings only. Contacts must be sourced separately and are not included in the package.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. These parts do not require dry-pack storage or baking procedures.

Q: Can these receptacles accommodate different contact types?

A: These housings are designed for crimp-terminated female socket contacts. Contact compatibility is determined by the contact termination specification and the 0.156" (3.96mm) pitch requirement.

Q: What is the significance of the locking ramp fastening type?

A: The locking ramp fastening mechanism provides positive mating and retention between the receptacle housing and its corresponding plug connector. This ensures secure connection and prevents accidental disconnection during operation.

Q: Are there any differences in the HTSUS codes between these parts?

A: Part 647401-9 and 2132189-9 share HTSUS code 8536.69.8000, while 640250-9 uses 8538.90.6000. These differences reflect tariff classification variations but do not affect functional equivalence or interchangeability.
