Engineering Selection Recommendations

The TE Connectivity 2-1761608-7 serves as the direct active equivalent for the obsolete 1761687-7. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part 2-1761608-7 maintains active product status within the TE Connectivity AMP-Latch series, ensuring ongoing availability and manufacturer support. The obsolete status of 1761687-7 necessitates transition to this active equivalent for all new designs and ongoing procurement requirements.

Electrical Performance Equivalence: Both parts maintain identical electrical specifications across all critical parameters: 20-position configuration, 0.100" (2.54mm) pitch, 1A per contact current rating, and 250VAC voltage rating. Contact material, finish specifications, and thickness values are identical, ensuring equivalent electrical performance in circuit applications.

Mechanical Compatibility: The substitute part maintains identical mechanical specifications for mounting, shrouding, termination, and fastening. Minor variations in contact length and insulation height (0.237" versus 0.240" mating contact length; 0.404" versus 0.350" insulation height) remain within functional equivalence for through-hole board mounting applications. These dimensional variations do not affect connector mating or board-level integration.

Compliance and Environmental Specifications: Both parts maintain identical compliance certifications: ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Operating temperature range (-65°C ~ 105°C) and environmental performance specifications are identical. The substitute part carries identical export classification (EAR99) and tariff coding (HTSUS 8536.69.4040).

Contact Finish Enhancement: The substitute part 2-1761608-7 offers optional gold-palladium mating contact finish in addition to standard gold, providing enhanced corrosion resistance and contact reliability without compromising electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 2-1761608-7 substitute directly replace the 1761687-7 in existing designs?

A: Yes. The substitute part maintains identical electrical, mechanical, and environmental specifications.
