Amphenol ICC 75691-006 Socket Contact Rectangular Connector

Part Overview

The Amphenol ICC 75691-006 is a socket contact rectangular connector designed for 22-26 AWG wire gauges with gold plating and crimp termination. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The Mini-PV™ series connector provides reliable interconnection in applications requiring socket-type contacts with gold finish specifications.

Substitute Part Grouping Explanation

Substitution for the 75691-006 is determined by the following critical parameters:

Wire gauge compatibility: 22-26 AWG
Contact termination method: Crimp
Contact finish: Gold plating
Moisture sensitivity level: 1 (Unlimited)
Electrical category: Rectangular connectors

Direct equivalent substitutes maintain socket contact configuration with gold finish. Alternative substitutes from Molex include non-gendered contacts with equivalent electrical and mechanical specifications. Socket-type alternatives are preferred for direct replacement; non-gendered contacts may be used where application design permits contact type flexibility.

Engineering Selection Recommendations

The 75691-006LF is the primary direct equivalent, maintaining socket contact configuration and gold finish while offering active product status and RoHS compliance. This part is recommended for applications requiring socket-type contacts with gold plating specifications.

Molex KK 2578 series contacts (0008550123, 0008550137, 0008580125, 0008650110) provide non-gendered alternatives with gold finish and active product status. These parts are suitable for applications where contact type flexibility is acceptable within the connector system design.

Molex KK Trifurcon 7258 series contacts (0008560123, 0008650121, 0008650122) offer gold-plated non-gendered contacts with active status and ROHS3 compliance. The 0008560123 provides the highest inventory availability in Cut Tape packaging.

The Molex 0503728000 socket contact provides socket-type configuration matching the original part's contact type; however, tin finish differs from the gold specification of the 75691-006. This part is suitable only for applications where tin finish is electrically and mechanically acceptable.

All substitute parts maintain 22-26 AWG wire gauge compatibility and crimp termination. All Molex alternatives provide ROHS3 compliance and active product status, addressing the obsolete status of the original part.

Frequently Asked Questions (FAQ)

Q: Can Molex non-gendered contacts replace the Amphenol ICC socket contact?

A: Non-gendered contacts are electrically and mechanically compatible with 22-26 AWG crimp termination and gold finish specifications. Compatibility depends on connector housing design and application requirements. Socket-type contacts (75691-006LF or 0503728000) provide direct contact type equivalence.

Q: What is the difference between the packaging options?

A: Tape & Reel (TR) packaging provides automated assembly compatibility. Cut Tape (CT) packaging offers flexibility for manual or semi-automated processes. Bulk packaging is suitable for high-volume applications without specific packaging requirements. Selection depends on production assembly methodology.

Q: Why does the 0503728000 have tin finish instead of gold?

A: The 0503728000 is a socket contact alternative from the Molex Mi II 50372 series. Tin finish provides equivalent electrical conductivity for 22-26 AWG applications. Gold finish selection is required only if corrosion resistance or specific contact resistance specifications mandate gold plating.

Q: Are all substitute parts RoHS compliant?

A: The original 75691-006 is RoHS non-compliant. The 75691-006LF and all Molex alternatives are RoHS3 compliant, meeting current regulatory requirements for new production and procurement.

Q: What inventory levels are available for these substitutes?

A: Inventory availability varies by part number. The 0008560123 offers the highest availability at 20,901 pieces. The 0008650121 provides 49,332 pieces. Other alternatives maintain active inventory levels suitable for production requirements.
