TE Connectivity 3-87977-1 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-87977-1 is a 12-position rectangular connector receptacle housing designed for 0.100" (2.54mm) pitch applications. This component is part of the AMPMODU Mod IV series and serves as the insulation housing for female socket contacts in free-hanging, in-line configurations. The part is actively manufactured and RoHS compliant.

Substitute parts are identified when equivalent rectangular connector housings share the same electrical and mechanical specifications: 12 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing, receptacle type with female socket contacts, crimp termination, and compatible operating temperature ranges. Alternative housings may differ in insulation material composition or color while maintaining functional equivalence.

Engineering Selection Recommendations

Primary Substitutes (Same Series, Same Temperature Range):

Parts 87977-4, 87456-7, and 1-86177-3 are direct substitutes within the AMPMODU Mod IV series, maintaining the -65°C to 105°C operating temperature specification. These parts differ only in insulation material composition (Thermoplastic versus Polyamide/Nylon). Selection among these options depends on application-specific material requirements. Part 87977-4 offers the highest inventory availability (7991 units).

Cross-Series Substitutes (Extended Temperature Range):

Parts 1-968318-1 and 1394048-1 from the Micro Quadlok series provide an extended operating temperature range of -40°C to 120°C and carry ROHS3 compliance. These parts are suitable for applications requiring higher temperature performance. Part 1394048-1 provides the highest inventory level (5200 units) among all substitutes.

Color Variants:

Part 2-968318-1 (Gray) and 925370-6 (Green) are functionally equivalent to the 3-87977-1 but differ in housing color. These are selected when color coding or visual identification requirements specify non-black housings.

Compliance Considerations:

All substitute parts maintain MSL Level 1 (Unlimited) moisture sensitivity and are either RoHS Compliant or ROHS3 Compliant. Parts carrying ROHS3 designation (1-86177-3, 1-87133-1, 1-968318-1, 1394048-1, 926476-6) represent updated compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 3-87977-1 with 1394048-1?

A: Yes. Both parts share identical electrical and mechanical specifications: 12 positions, 0.100" pitch, 2-row configuration, receptacle type with female socket contacts, and crimp termination. The primary difference is the extended operating temperature range (-40°C to 120°C versus -65°C to 105°C) and insulation material (PBT glass-filled versus Polyamide). Substitution is valid for applications within the overlapping temperature range (-40°C to 105°C).

Q: What is the difference between AMPMODU Mod IV and Micro Quadlok series substitutes?

A: Both series provide 12-position, 0.100" pitch receptacle housings with identical contact configurations. AMPMODU Mod IV parts (3-87977-1, 87977-4, 87456-7, 1-86177-3) operate at -65°C to 105°C. Micro Quadlok parts (1-968318-1, 1394048-1, 2-968318-1) operate at -40°C to 120°C. Series selection depends on application temperature requirements and connector interface compatibility with mating plugs.

Q: Are color variants functionally equivalent?

A: Yes. Parts 2-968318-1 (Gray) and 925370-6 (Green) are functionally identical to the black 3-87977-1 in all electrical and mechanical parameters. Color differences serve visual identification purposes only and do not affect electrical performance or mechanical compatibility.

Q: What does MSL Level 1 mean for this connector housing?

A: MSL Level 1 indicates unlimited moisture sensitivity, meaning the component has no moisture absorption restrictions and requires no special handling, storage, or baking procedures prior to assembly. This applies to all listed substitute parts.

Q: Can I use 87977-4 as a direct replacement for 3-87977-1?

A: Yes. Part 87977-4 is a direct substitute within the same AMPMODU Mod IV series. Both parts maintain identical specifications for positions, pitch, row configuration, mounting type, and operating temperature range. The only difference is the insulation material (Thermoplastic versus Polyamide/Nylon Glass Filled).

Q: Which substitute offers the best inventory availability?

A: Part 87977-4 provides the highest inventory level at 7991 units, followed by 1394048-1 at 5200 units. Both are suitable substitutes depending on application requirements.

Q: Do all substitutes require the same contact specifications?

A: Yes. All listed substitute housings are designed for identical crimp-terminated female socket contacts at 0.100" (2.54mm) pitch. Contact selection and specifications remain unchanged regardless of which housing substitute is selected.
