TE Connectivity 1-281839-5 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-281839-5 is a 30-position rectangular connector housing designed for receptacle applications with 0.100" (2.54mm) pitch spacing. This component functions as a housing for female socket contacts in dual-row configurations and is classified as a free-hanging, in-line connector. The part is currently active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters are required but the original part number is unavailable or when alternative material compositions or color specifications are necessary for system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (30), pitch spacing (0.100"/2.54mm), row configuration (2 rows with 0.100" spacing), mounting method (free hanging in-line), contact termination method (crimp), and fastening mechanism (detent lock). The substitute part 2-87631-5 maintains full electrical and mechanical compatibility across all these parameters. Variations in insulation material composition (polybutylene terephthalate glass-filled versus polyamide nylon glass-filled), color specification (blue versus black), operating temperature range, and connector series designation do not affect functional interchangeability for housing applications where contacts are supplied separately.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-281839-5 and 2-87631-5 are active production parts manufactured by TE Connectivity with full RoHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is based on specific application requirements rather than compliance or availability constraints. The 1-281839-5 (HE13/HE14 series, blue, PBT insulation) operates across a wider temperature range (-55°C to 125°C) and is suitable for applications requiring extended high-temperature performance. The 2-87631-5 (AMPMODU Mod IV series, black, polyamide insulation) provides lower temperature operation (-65°C to 105°C) and is appropriate for applications requiring extended low-temperature capability. Both parts share identical electrical and mechanical specifications for the 30-position, dual-row, 2.54mm pitch configuration. Selection should be driven by color coding requirements, material preference, and operating temperature envelope specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Are the 1-281839-5 and 2-87631-5 housings mechanically interchangeable?

A: Yes. Both housings maintain identical pitch spacing (0.100"/2.54mm), position count (30), row configuration (2 rows), and mounting method (free hanging in-line). The housings are mechanically interchangeable in applications where the connector series and color designation do not impose system constraints.

Q: What is the significance of the different insulation materials (PBT versus polyamide)?

A: The insulation material affects mechanical properties and temperature performance. PBT (polybutylene terephthalate) in the 1-281839-5 provides higher temperature capability (125°C maximum). Polyamide (nylon) in the 2-87631-5 offers lower temperature performance (-65°C minimum). Both materials are glass-filled for structural reinforcement and are suitable for crimp termination applications.

Q: Can I use the 2-87631-5 substitute if my application requires operation at 120°C?

A: No. The 2-87631-5 has a maximum operating temperature of 105°C. For applications requiring sustained operation at 120°C, the 1-281839-5 with its 125°C maximum rating is the appropriate selection.

Q: Are contacts included with these housings?

A: No. Both the 1-281839-5 and 2-87631-5 are housings only. Contacts must be supplied separately and crimped into the housing positions.

Q: What is the difference between the HE13/HE14 series and AMPMODU Mod IV series designations?

A: These are different connector series within the TE Connectivity product line. The series designation indicates the connector family and design generation. Both series provide 30-position, dual-row, 2.54mm pitch housings with identical electrical and mechanical specifications for this application.

Q: Does the color difference (blue versus black) affect electrical performance?

A: No. Color is a visual identification feature only and does not affect electrical performance or mechanical function. Color selection is typically driven by system documentation, assembly procedures, or customer specifications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 1-281839-5 and 2-87631-5 are RoHS3 compliant with unlimited moisture sensitivity ratings (MSL 1), indicating no special storage or handling requirements.
