Amphenol ICC 75691-003 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75691-003 is a socket contact connector for 18-20 AWG wire with gold plating, part of the Mini-PV™ Basics+ series. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The part operates within unlimited moisture sensitivity conditions and maintains compatibility with standard rectangular connector applications requiring crimp termination.

Substitute Part Grouping Explanation

Substitution for the 75691-003 is determined by the following critical parameters: wire gauge (18-20 AWG), contact termination method (crimp), and moisture sensitivity level (MSL 1). The substitute parts are grouped into two functional categories:

Category 1: Direct Rectangular Connector Substitutes — Parts maintaining socket contact configuration with 18-20 AWG crimp termination. These include Molex rectangular connectors (0008520112, 0008580187, 0334680003, 0334680004) and TE Connectivity 1326028-1, all with active product status and RoHS3 compliance.

Category 2: Blade Type Power Connector Substitutes — Parts utilizing blade contact geometry with 18-20 AWG crimp termination. These include Molex High Normal Force (HNF) series (0945180100, 0945180101) and VersaBlade series (0357480310), all with active product status and RoHS3 compliance.

Both categories maintain the 18-20 AWG wire gauge requirement and crimp termination method. Contact finish variations (tin vs. gold) and contact material differences (brass vs. phosphor bronze) are secondary parameters that do not prevent functional substitution within the specified wire gauge and termination constraints.

Engineering Selection Recommendations

All listed substitute parts maintain active product status with ROHS3 compliance, providing long-term availability and regulatory alignment superior to the obsolete 75691-003. Selection between rectangular connector and blade type power connector substitutes depends on the connector housing and mating interface requirements of the target application.

For applications requiring gold contact finish matching the original 75691-003 specification, Molex 0008580187 and TE Connectivity 1326028-1 provide direct equivalents with socket contact configuration and active product status. Both parts are RoHS3 compliant and maintain the 18-20 AWG wire gauge requirement.

For applications where tin contact finish is acceptable, Molex 0334680003 and 0334680004 offer socket contact alternatives with active status and RoHS3 compliance. These parts are available in higher inventory quantities, supporting volume production requirements.

Blade type power connector substitutes (Molex 0945180100, 0945180101, 0357480310) are applicable only when the connector housing and mating interface support blade contact geometry. These parts maintain 18-20 AWG compatibility and active product status with RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 75691-003 be directly replaced with any of these substitute parts?

A: Direct replacement depends on connector housing compatibility. The 75691-003 is a socket contact for rectangular connectors. Molex 0334680003, 0334680004, 0008580187, 0008520112, and TE Connectivity 1326028-1 are compatible with rectangular connector housings. Blade type connectors (0945180100, 0945180101, 0357480310) require blade-compatible housings and are not direct mechanical replacements.

Q: What is the difference between tin and gold contact finishes for 18-20 AWG crimp contacts?

A: Contact finish is a secondary parameter that does not affect wire gauge or crimp termination compatibility. Gold finish (0008580187, 1326028-1) provides enhanced corrosion resistance in high-reliability applications. Tin finish (0334680003, 0334680004, 0945180101) is suitable for standard industrial applications. Selection depends on environmental exposure and reliability requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant, whereas the original 75691-003 is RoHS non-compliant. This compliance upgrade is a regulatory advantage for new designs and systems requiring RoHS certification.

Q: What packaging options are available for these substitute parts?

A: Substitute parts are available in Cut Tape (CT), Tape & Reel (TR), and Bulk packaging. Packaging selection depends on production volume and assembly process requirements. High-volume applications typically utilize Tape & Reel packaging, while lower volumes may use Cut Tape or Bulk options.

Q: Can the 75691-003 be used interchangeably with non-gendered contacts like Molex 0008520112?

A: Non-gendered contacts (0008520112, 0008580187) are functionally compatible with 18-20 AWG crimp termination but may have different mating interface geometry compared to gendered socket contacts. Compatibility depends on the specific connector housing design. Verify housing specifications before substitution.
