TE Connectivity AMP Connectors 3-1437290-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 3-1437290-9 is a 34-position rectangular connector housing designed for the Superseal series. This plug housing accommodates female socket contacts with a 3.00mm pitch configuration across 4 rows and utilizes crimp termination with latch lock fastening. The connector is rated for operating temperatures between -40°C and 125°C and is constructed from thermoplastic polyester insulation material. This part is actively manufactured and RoHS compliant. Substitute parts are identified when inventory availability requires alternative sourcing or when equivalent electrical and mechanical specifications are required for system integration.

Frequently Asked Questions (FAQ)

Q: Can the 4-1437290-0 be used as a direct replacement for the 3-1437290-9?

A: Yes. The 4-1437290-0 is a parametric equivalent with identical electrical and mechanical specifications, including connector type, contact configuration, pitch, row arrangement, termination method, fastening mechanism, insulation material, and operating temperature range.

Q: Are there any differences in RoHS compliance or environmental certifications between these parts?

A: No. Both the 3-1437290-9 and 4-1437290-0 are RoHS compliant and carry identical MSL Level 1 (Unlimited) ratings. Both parts meet the same environmental and regulatory standards.

Q: What is the significance of the different part numbers if the specifications are identical?

A: Different part numbers within the same base product family (1437290) may reflect manufacturing date codes, internal revision levels, or supplier batch designations. From an engineering perspective, both parts meet identical functional and mechanical requirements.

Q: Do these connector housings include contacts?

A: No. Both the 3-1437290-9 and 4-1437290-0 are connector housings only. Female socket contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: What is the pitch specification and why is it important for substitution?

A: The pitch is 0.118" (3.00mm), representing the center-to-center distance between adjacent contact positions. This specification must match exactly for proper contact alignment and mating with corresponding plug connectors. Both substitute parts maintain identical pitch specifications.

Q: Are these parts suitable for automotive applications?

A: Both parts are manufactured as Superseal series connectors, which are commonly used in automotive and industrial applications. The operating temperature range of -40°C to 125°C and RoHS compliance support use in these environments. Specific application suitability should be confirmed against system requirements.
