Amphenol ICC 75915-409 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75915-409 is a 9-position receptacle connector from the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole solder termination. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and new design implementations. Substitute parts must maintain compatibility across connector type, position count, pitch, mounting method, and contact configuration to ensure proper mechanical and electrical integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 75915-409 is determined by strict alignment with the following core parameters: connector type (receptacle), position count (9), mating pitch (0.100"), mounting method (through hole), termination type (solder), and fastening mechanism (push-pull). Parts meeting these criteria are classified into two categories:

Direct Equivalent (Same Manufacturer): Parts maintaining identical mechanical and electrical specifications within the same manufacturer product line, differing only in contact finish or compliance status.

Cross-Manufacturer Substitute: Parts from alternative manufacturers that satisfy all core mechanical parameters and fastening requirements, though may exhibit variations in contact material, insulation composition, or electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

75915-409LF (Direct Equivalent - Preferred for Active Designs): This Amphenol ICC part maintains identical mechanical dimensions and contact geometry while offering active product status and RoHS compliance. The transition from tin-lead to tin contact finish represents a material upgrade aligned with modern manufacturing standards. This part is the primary recommendation for new designs and obsolescence mitigation strategies.

929974-01-09 (Cross-Manufacturer Substitute - Alternative Option): The 3M 929974-01-09 satisfies all core mechanical substitution criteria and provides active product status with specified electrical ratings (2A, 1500V) and operating temperature range (-40°C ~ 105°C). Dimensional variations exist in insulation height (0.325" vs. 0.335") and contact post length (0.125" vs. 0.114"), requiring PCB layout verification. Contact type differs (forked vs. socket), which may affect mating force and contact reliability characteristics. This part is suitable where Amphenol ICC alternatives are unavailable and mechanical tolerance analysis confirms compatibility.

Frequently Asked Questions (FAQ)

Q: Can 75915-409LF be used as a direct replacement for 75915-409?

A: Yes. The 75915-409LF maintains identical mechanical dimensions, position count, pitch, mounting method, and contact geometry. The primary difference is contact finish material (tin vs. tin-lead) and product status (active vs. obsolete). RoHS compliance of the 75915-409LF makes it the preferred choice for new applications.

Q: What are the key differences between 75915-409 and 929974-01-09?

A: Both parts share identical connector type, position count, pitch, mounting method, and fastening mechanism. Differences include: contact type (female socket vs. forked), insulation height (0.335" vs. 0.325"), contact post length (0.114" vs. 0.125"), insulation material composition (thermoplastic vs. PCT), and contact material (phosphor bronze vs. copper alloy). The 929974-01-09 provides specified electrical ratings and operating temperature range.

Q: Are there packaging differences between these parts?

A: Yes. The 75915-409 has unspecified packaging, 75915-409LF is supplied in tube packaging, and 929974-01-09 is supplied in bulk packaging. Packaging selection should align with procurement and assembly requirements.

Q: Which substitute is recommended for RoHS-compliant applications?

A: The 75915-409LF is RoHS compliant and is the recommended choice for applications requiring RoHS certification. The 929974-01-09 is RoHS non-compliant.

Q: Can 929974-01-09 be used if PCB layout is already designed for 75915-409?

A: Mechanical verification is required. The 929974-01-09 has a 0.010" (0.25mm) shorter insulation height and 0.011" (0.28mm) longer contact post compared to the 75915-409. These dimensional differences may require PCB layout adjustment to ensure proper connector seating and contact engagement.
