TE Connectivity 3-87977-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-87977-3 is a 16-position rectangular connector receptacle housing designed for 0.100" (2.54mm) pitch applications. This component belongs to the AMPMODU Mod IV series and features a black polyamide housing with crimp-type female socket contacts. The part is classified as Active product status with full RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent rectangular connectors share the same core electrical and mechanical specifications: 16 positions, 2-row configuration, 0.100" pitch, 0.100" row spacing, receptacle type with female socket contacts, crimp termination, free-hanging in-line mounting, and compatible operating temperature ranges. Alternative sources and housing materials may be selected based on application requirements and inventory availability.

Engineering Selection Recommendations

Primary Equivalent (Identical Specifications): The TE Connectivity 1-87456-2 provides direct parametric equivalence to the 3-87977-3, sharing identical electrical, mechanical, and environmental specifications within the AMPMODU Mod IV series. Both parts operate across -65°C to 105°C and maintain RoHS compliance. The 1-87456-2 offers higher inventory availability (1612 units versus 969 units).

Extended Temperature Range Alternatives: The TE Connectivity 104482-7 and Amphenol ICC 65239-008LF both support extended operating temperatures to 125°C, providing thermal margin for applications requiring higher temperature performance. The 104482-7 maintains TE Connectivity sourcing within the AMPMODU family with the highest inventory level (3135 units). The 65239-008LF offers blue housing identification with REACH Affected status.

Color-Coded Alternative: The TE Connectivity 925370-8 provides green housing within the AMPMODU Mod IV series, maintaining identical electrical and thermal specifications (-65°C to 105°C) while offering visual circuit identification through color differentiation.

Cross-Manufacturer Option: The Molex 0901430016 (C-Grid III 90143 series) provides equivalent 16-position, 2.54mm pitch receptacle housing with ROHS3 compliance. Operating temperature range is -55°C to 105°C, which covers the primary operating window of the 3-87977-3 with a reduced lower temperature limit.

Limited Temperature Range Option: The Amphenol ICC 65043-029LF (Mini-PV™ series) operates within -40°C to 105°C, suitable for applications not requiring extended low-temperature performance below -40°C.

All substitute parts maintain RoHS compliance, unlimited moisture sensitivity rating (MSL 1), crimp termination, and free-hanging in-line mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-87456-2 be used as a direct replacement for the 3-87977-3?

A: Yes. Both parts share identical specifications: 16 positions, 0.100" pitch, 2-row configuration, female socket contacts, crimp termination, and -65°C to 105°C operating range. Both are RoHS compliant with MSL 1 rating. The 1-87456-2 is a parametric equivalent within the AMPMODU Mod IV series.

Q: What is the difference between the TE Connectivity 104482-7 and the 3-87977-3?

A: The 104482-7 extends the maximum operating temperature to 125°C compared to 105°C on the 3-87977-3. All other electrical and mechanical parameters are identical. The insulation material differs (thermoplastic versus polyamide), and the series designation is AMPMODU rather than AMPMODU Mod IV. Both are RoHS compliant.

Q: Are the color variations (black, green, blue) electrically equivalent?

A: Yes. The 925370-8 (green), 65239-008LF (blue), and black variants (3-87977-3, 1-87456-2, 104482-7, 0901430016, 65043-029LF) are electrically and mechanically equivalent. Color serves as visual identification only and does not affect electrical performance or compatibility.

Q: What is the significance of the Molex 0901430016 having a lower minimum operating temperature (-55°C versus -65°C)?

A: The Molex part operates from -55°C to 105°C, which narrows the lower temperature specification by 10°C. For applications requiring operation below -55°C, the TE Connectivity or Amphenol ICC alternatives with -65°C minimum ratings are required.

Q: Can I use the Amphenol ICC 65043-029LF if my application operates at -50°C?

A: No. The 65043-029LF operates from -40°C to 105°C. Applications requiring operation below -40°C require alternatives with lower temperature ratings: 3-87977-3, 1-87456-2, 104482-7, 925370-8, or 65239-008LF (all rated to -65°C).

Q: What does "Contacts Not Included" mean for all these parts?

A: These part numbers specify the connector housing only. Contact pins or sockets must be ordered separately and are not included in the housing assembly. Verify that replacement contacts are compatible with the selected housing before assembly.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry RoHS compliance certification. The TE Connectivity and Amphenol ICC parts are RoHS Compliant; the Molex part is ROHS3 Compliant. All meet RoHS requirements for hazardous substance restrictions.

Q: Which substitute part has the highest inventory availability?

A: The TE Connectivity 104482-7 has the highest inventory with 3135 units in stock, followed by the 925370-8 with 1691 units and the 1-87456-2 with 1612 units.

Q: Can I mix and match housings from different manufacturers in the same connector assembly?

A: Connector housings from different manufacturers (TE Connectivity, Molex, Amphenol ICC) are not designed for interchangeability within a single mated pair. Select a single manufacturer source for both plug and receptacle components to ensure proper fit and electrical performance.
