Key Parameters

Substitute Part Grouping Explanation

The substitute part 770008-3 is functionally equivalent to the main part 770251-3 based on the following critical parameters that determine substitutability:

• Series Compatibility: Both parts belong to the Universal MATE-N-LOK II series
• Contact Type: Both are socket contacts with identical crimp termination
• Wire Gauge Rating: Both accommodate 14-20 AWG wire sizes
• Contact Finish: Both feature tin plating for identical electrical properties
• Compliance Standards: Both maintain ROHS3 compliance and MSL 1 rating
• Electrical Classification: Both are classified under HTSUS 8536.90.4000 and ECCN EAR99

The primary distinction between these parts is packaging configuration. The main part 770251-3 is supplied in bulk packaging, while the substitute 770008-3 is supplied in cut tape (CT) packaging. This packaging difference does not affect the electrical or mechanical performance of the contact itself and allows for selection based on assembly process requirements and inventory management strategies.

Parameter Comparison

Engineering Selection Recommendations

Both 770251-3 and 770008-3 are suitable for direct substitution in applications requiring Universal MATE-N-LOK II series socket contacts with 14-20 AWG crimp termination and tin contact finish. Selection between these parts should be based on the following factors:

770251-3 (Bulk Packaging): Appropriate for high-volume production runs, manual assembly operations, or applications where loose component handling is standard practice.

770008-3 (Cut Tape Packaging): Appropriate for automated assembly processes, pick-and-place equipment integration, or applications requiring component-level traceability and controlled dispensing.

Both parts maintain active production status and full RoHS3 compliance, ensuring long-term availability and regulatory conformance. The electrical and mechanical performance characteristics are identical across both packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can 770008-3 be used as a direct replacement for 770251-3 in existing designs?

A: Yes. The 770008-3 is electrically and mechanically identical to 770251-3. The only difference is packaging format. Both parts are rated for 14-20 AWG wire gauges, feature tin contact finish, and are compatible with Universal MATE-N-LOK II connector systems.

Q: What is the primary difference between these two part numbers?

A: The primary difference is packaging. The 770251-3 is supplied in bulk packaging, while the 770008-3 is supplied in cut tape (CT) packaging. This affects handling, dispensing, and inventory management but does not impact electrical or mechanical performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 770251-3 and 770008-3 are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for automated assembly?

A: The 770008-3 in cut tape packaging is designed for automated assembly processes and pick-and-place equipment. The 770251-3 in bulk packaging is suitable for manual assembly or high-volume loose component handling.

Q: Do these parts have different wire gauge ratings?

A: No. Both parts are rated for identical 14-20 AWG wire gauge specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS3 compliance status, ECCN classification (EAR99), and HTSUS code (8536.90.4000).
