Amphenol ICC 75915-407 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75915-407 is a 7-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 substitute parts are necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 75915-407 is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle with 7 positions
• Pitch & Mounting: 0.100" (2.54mm) pitch with through-hole solder termination
• Style: Board-to-board configuration
• Fastening Type: Push-pull mechanism
• Flammability: UL94 V-0 rating

The substitute parts listed maintain these core electrical and mechanical parameters, ensuring functional compatibility with existing designs.

Engineering Selection Recommendations

75915-407LF (Amphenol ICC - Recommended Primary Substitute)

The 75915-407LF is the direct successor to the 75915-407 within the same manufacturer's Dubox™ series. It maintains identical mechanical dimensions and pitch specifications. The primary difference is the contact finish (tin versus tin-lead) and RoHS compliance status. This part is currently in active production with higher inventory availability.

929974-01-07 (3M - Alternative Substitute)

The 929974-01-07 from 3M's 929 series provides functional equivalence with specified electrical ratings (2A current, 1500V voltage) and operating temperature range (-40°C ~ 105°C). Minor dimensional variations exist in insulation height (0.325" versus 0.335") and contact post length (0.125" versus 0.114"), which may require PCB layout verification. This part is RoHS non-compliant, matching the original part's compliance status.

Frequently Asked Questions (FAQ)

Q: Can 75915-407LF directly replace 75915-407 in existing designs?

A: Yes. The 75915-407LF maintains identical pitch (0.100"), position count (7), mounting type (through-hole), and mechanical envelope. The contact finish difference (tin versus tin-lead) does not affect mechanical compatibility. RoHS compliance of the substitute may be relevant for regulatory requirements.

Q: What are the dimensional differences between 75915-407 and 929974-01-07?

A: The 929974-01-07 has a slightly lower insulation height (0.325" versus 0.335") and longer contact post (0.125" versus 0.114"). These differences require verification against PCB footprint and mating connector specifications before implementation.

Q: Is the 929974-01-07 suitable for applications requiring electrical ratings?

A: The 929974-01-07 provides specified electrical ratings (2A, 1500V) and operating temperature range (-40°C ~ 105°C). The original 75915-407 does not specify these parameters. Verify that application requirements align with the 3M part's ratings.

Q: What is the difference between tin and tin-lead contact finishes?

A: Both finishes provide solder compatibility for through-hole termination. Tin-lead finishes are associated with legacy designs, while tin finishes align with modern RoHS compliance requirements. Soldering process parameters may require adjustment based on finish type.

Q: Are there packaging differences between these substitutes?

A: Yes. The 75915-407 packaging is not specified. The 75915-407LF is supplied in tube packaging. The 929974-01-07 is supplied in bulk packaging. Packaging affects handling, storage, and procurement logistics.
