Amphenol ICC 75915-422 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75915-422 is a 22-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using through-hole solder termination. This connector features tin-lead contact finish and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and component sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the 75915-422 is determined by the following critical parameters:

Connector Type & Position Count: Must be receptacle with 22 positions
Pitch & Spacing: Must maintain 0.100" (2.54mm) mating pitch
Mounting & Termination: Must support through-hole solder termination
Fastening Mechanism: Must use push-pull fastening
Contact Finish: Tin-lead or tin finish acceptable
Insulation & Flammability: Must meet UL94 V-0 rating

The identified substitute parts meet these core electrical and mechanical compatibility criteria. Variations in contact type (female socket vs. forked), insulation material composition, and compliance status are noted but do not prevent functional substitution within the specified parameter constraints.

Engineering Selection Recommendations

75915-422LF (Direct Substitute - Amphenol ICC)

The 75915-422LF is the direct equivalent from the same manufacturer series. It maintains identical mechanical and electrical specifications to the main part while offering active product status. The primary distinction is the contact finish (tin vs. tin-lead) and RoHS compliance. This part is recommended for applications requiring continuity with the original design and where RoHS compliance is mandated.

929974-01-22 (Cross-Manufacturer Substitute - 3M)

The 929974-01-22 provides functional equivalence with differences in contact type (forked vs. socket), insulation material composition, and dimensional tolerances. This part is active and includes specified electrical ratings (2A current, 1500V voltage) and operating temperature range (-40°C ~ 105°C). Selection of this substitute requires verification that the forked contact configuration is compatible with the mating connector design and that dimensional variations in insulation height and contact post length do not conflict with board layout constraints.

Frequently Asked Questions (FAQ)

Q: Can 75915-422LF be used as a direct replacement for 75915-422?

A: Yes. The 75915-422LF maintains identical pitch, position count, mounting type, and termination method. The contact finish differs (tin vs. tin-lead), but both finishes are compatible with standard solder processes. The primary advantage is active product status and RoHS compliance.

Q: What is the key difference between 75915-422LF and 929974-01-22?

A: Both are 22-position, 0.100" pitch receptacles suitable for board-to-board applications. The 929974-01-22 uses forked contacts instead of female sockets, has a different insulation material (PCT vs. thermoplastic), and includes specified electrical ratings. Mechanical compatibility depends on the mating connector design.

Q: Are there packaging differences between these parts?

A: Yes. The 75915-422 and 75915-422LF are supplied in different packaging formats (unspecified vs. tube). The 929974-01-22 is supplied in bulk packaging. Packaging selection should align with production volume and handling requirements.

Q: Does the contact finish difference affect electrical performance?

A: Both tin and tin-lead finishes provide equivalent electrical conductivity and solder joint reliability when used with standard PCB assembly processes. Selection between them is typically driven by RoHS compliance requirements and process specifications.

Q: What are the dimensional constraints for substitution?

A: The insulation height and contact post length vary slightly between parts. The 929974-01-22 has a 0.010" (0.26mm) lower insulation height and 0.011" (0.28mm) longer contact post. These differences must be evaluated against specific board layout and mating connector specifications.
