TE Connectivity 2-87631-3 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-87631-3 is a 28-position rectangular connector receptacle housing from the AMPMODU Mod IV series. This component functions as a female socket housing for applications requiring dual-row, 0.100" pitch interconnection. The part is classified as Active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 2-87631-3 are identified based on strict parametric equivalence across all critical electrical and mechanical dimensions. The substitution logic is based on the following key parameters that must remain identical:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 28 positions at 0.100" (2.54mm) pitch
• Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
• Mounting & Termination: Free hanging in-line mounting with crimp contact termination
• Fastening Mechanism: Detent lock fastening type
• Material & Environmental Ratings: Polyamide nylon glass-filled insulation, -65°C to 105°C operating range
• Compliance Standards: RoHS compliance and MSL 1 rating

The substitute part 2-87631-4 maintains complete parametric alignment with the main part across all specified dimensions and environmental performance criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the 2-87631-3 and 2-87631-4 are Active product status components manufactured by TE Connectivity within the AMPMODU Mod IV series. The parts are functionally and mechanically interchangeable for all applications requiring 28-position, dual-row rectangular connector housings at 0.100" pitch.

The 2-87631-4 substitute part carries ROHS3 compliance designation, which represents an enhanced RoHS compliance status compared to the standard RoHS Compliant rating of the main part. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and identical operating temperature specifications of -65°C to 105°C.

Selection between these parts should be based on procurement availability and lead time requirements. The 2-87631-4 currently maintains higher inventory availability (1943 pieces) compared to the 2-87631-3 (662 pieces), making it suitable for applications with extended production schedules or bulk procurement needs.

Frequently Asked Questions (FAQ)

Q: Are the 2-87631-3 and 2-87631-4 directly interchangeable in existing designs?

A: Yes. Both parts are identical in all electrical and mechanical parameters including connector type, position count, pitch, row configuration, mounting type, contact termination, and fastening mechanism. They are direct substitutes within the AMPMODU Mod IV series.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant designations?

A: ROHS3 represents compliance with the third iteration of RoHS regulations and indicates enhanced regulatory alignment. Both designations confirm the parts meet RoHS requirements; ROHS3 reflects the most current regulatory standard.

Q: Do these connector housings include contacts?

A: No. Both the 2-87631-3 and 2-87631-4 are housings only. Contacts must be procured separately and installed via crimp termination.

Q: What is the significance of the 0.100" pitch specification?

A: The 0.100" (2.54mm) pitch defines the center-to-center spacing between adjacent contact positions. This specification is critical for PCB layout, mating connector design, and contact alignment. Both parts maintain identical pitch specifications.

Q: Can these receptacle housings be used in high-temperature applications?

A: Yes. Both parts are rated for continuous operation across the -65°C to 105°C temperature range. The polyamide nylon glass-filled insulation material supports this full operating envelope.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these components have unlimited shelf life and do not require special moisture-controlled storage or handling procedures prior to assembly.

Q: Are there any packaging differences between the two parts?

A: Both parts are supplied in Bulk packaging. The primary difference is inventory availability, with the 2-87631-4 currently stocked at higher quantities.
