Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1761604-9 is determined by strict equivalence across the following critical parameters: connector type (header), contact type (male pin), number of positions (26), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole, right angle), shrouding configuration (shrouded 4-wall), termination method (solder), fastening type (push-pull), and operating temperature range (-65°C ~ 105°C).

The identified substitute parts 2-1761605-9 and 5103310-6 maintain full compliance with these core parameters. Both alternatives are active products within the AMP-Latch series, providing direct functional replacement capability. Differences in contact finish thickness, insulation material specifications, contact post length, and packaging format do not preclude substitution when these parameters fall within acceptable engineering tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 2-1761605-9 and 5103310-6 provide functional equivalence to the obsolete 1761604-9 across all critical electrical and mechanical parameters. Selection between these alternatives is determined by compliance requirements and packaging specifications.

2-1761605-9 is recommended for applications requiring RoHS compliance certification. This part maintains identical electrical specifications and mechanical dimensions to the main part, with enhanced contact finish thickness (30.0µin versus 15.0µin) providing improved durability. Bulk packaging format supports high-volume production environments.

5103310-6 is suitable for applications where ROHS3 compliance is mandated. This part features extended contact post length (0.135" versus 0.102"), which may require PCB design verification for through-hole depth compatibility. Tube packaging format accommodates lower-volume or maintenance applications. Contact material composition differs (brass versus phosphor bronze), and voltage rating specification is not provided.

For new designs or production transitions, 2-1761605-9 is the primary substitute due to active product status, RoHS compliance, and complete specification documentation. The 5103310-6 alternative serves applications where ROHS3 compliance is specifically required and contact post length extension is compatible with board design.

Frequently Asked Questions (FAQ)

Q: Can 2-1761605-9 and 5103310-6 be used interchangeably with 1761604-9?

A: Both parts maintain electrical and mechanical compatibility with 1761604-9 across mating pitch, row spacing, contact type, number of positions, mounting configuration, and operating temperature range. Physical differences in contact post length (5103310-6 features 0.135" versus 0.102" standard) require PCB design verification to confirm through-hole depth accommodation.

Q: What is the primary difference between the two substitute parts?

A: 2-1761605-9 features phosphor bronze contacts with standard post length and RoHS compliance. 5103310-6 features brass contacts with extended post length and ROHS3 compliance. Contact finish thickness on 2-1761605-9 is doubled (30.0µin), providing enhanced wear resistance.

Q: Does packaging format affect electrical performance?

A: Packaging format (bulk versus tube) does not affect electrical or mechanical performance. Selection is based on supply chain requirements, inventory management, and production volume specifications.

Q: Is the insulation color change from black to blue on 2-1761605-9 significant?

A: Insulation color is a visual identification feature and does not affect electrical performance or mechanical compatibility. Color change reflects manufacturing process updates between product generations.

Q: What compliance certifications apply to each substitute?

A: 2-1761605-9 carries RoHS Compliant certification. 5103310-6 carries ROHS3 Compliant certification. Both parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1).

Q: Are there voltage or current rating differences?

A: 2-1761605-9 maintains the 250VAC voltage rating and 1A per contact current rating of the main part. 5103310-6 does not specify voltage rating in available documentation, though current rating remains 1A per contact.

Q: How does contact finish thickness affect performance?

A: Contact finish thickness determines wear resistance and contact durability under mating cycles. 2-1761605-9 provides 30.0µin (0.76µm) mating finish thickness, compared to 15.0µin (0.38µm) on both 1761604-9 and 5103310-6, extending service life in high-cycle applications.
