Amphenol ICC 75915-412 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75915-412 is a 12-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 push-pull fastening, suitable for automotive, industrial, and telecommunications applications.

The 75915-412 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 75915-412 is determined by the following critical parameters:

• Connector Type & Contact Type: Must be receptacle with female socket contacts
• Number of Positions: Must be 12 positions
• Pitch - Mating: Must be 0.100" (2.54mm)
• Mounting Type: Must be through hole
• Termination: Must be solder
• Fastening Type: Must be push-pull
• Insulation Material & Flammability: Must maintain UL94 V-0 rating

Direct Equivalent (Same Series): The 75915-412LF is a direct equivalent within the Dubox™ series, differing only in contact finish composition (tin instead of tin-lead) and product status (active vs. obsolete).

Cross-Manufacturer Substitute: The 3M 929974-01-12 provides functional equivalence as a 12-position receptacle with matching pitch, mounting, and termination. However, it uses forked contacts instead of socket contacts and differs in insulation material and electrical ratings.

Non-Equivalent Part: The 76383-304LF is a header connector (male pin contacts) with 8 positions and right-angle mounting. This part does not meet substitution criteria due to incompatible connector type, contact type, position count, and mounting orientation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 75915-412LF is the recommended substitute. As an active product within the same Dubox™ series from Amphenol ICC (FCI), it maintains identical mechanical and electrical interface specifications. The primary difference is RoHS compliance status (75915-412LF is RoHS compliant versus the non-compliant 75915-412). Contact finish composition differs (tin versus tin-lead), which does not affect mechanical compatibility or mating performance.

For Cross-Manufacturer Substitution: The 3M 929974-01-12 provides functional equivalence for applications requiring a 12-position, 0.100" pitch receptacle connector with through-hole solder termination. This part is active and carries specified electrical ratings (2A current, 1500V voltage). However, the forked contact design differs from the socket contact design of the 75915-412, and insulation material composition differs. Mechanical fit and electrical performance characteristics may vary. This substitute is suitable only when design validation confirms compatibility with the forked contact interface.

Not Recommended: The 76383-304LF does not meet substitution criteria and is not recommended as an alternative to the 75915-412.

Frequently Asked Questions (FAQ)

Q: Can the 75915-412LF directly replace the 75915-412 in existing designs? A: Yes. The 75915-412LF maintains identical pitch (0.100"), position count (12), mounting type (through hole), and termination method (solder). Both use push-pull fastening and UL94 V-0 rated insulation. The primary design difference is contact finish composition (tin versus tin-lead), which does not affect mechanical mating or electrical interface compatibility.

Q: What is the significance of RoHS compliance in selecting a substitute? A: The 75915-412 is RoHS non-compliant, while the 75915-412LF is RoHS compliant. If your application or supply chain requires RoHS compliance, the 75915-412LF is the appropriate choice. If legacy RoHS non-compliant designs are acceptable, both parts are mechanically and electrically compatible.

Q: Why is the 3M 929974-01-12 listed as a cross-manufacturer substitute rather than a direct equivalent? A: While the 3M 929974-01-12 matches critical parameters (12 positions, 0.100" pitch, through-hole solder termination, push-pull fastening), it uses forked contacts instead of socket contacts. Forked contacts engage with male pins differently than socket contacts, and insulation material differs (PCT versus thermoplastic). These differences require design validation to confirm compatibility in your specific application.

Q: Is the 76383-304LF compatible with the 75915-412? A: No. The 76383-304LF is a header connector with male pin contacts, 8 positions, and right-angle mounting. It does not meet the substitution criteria for the 75915-412 receptacle connector.

Q: What packaging options are available for substitute parts? A: The 75915-412LF is available in tube packaging. The 3M 929974-01-12 is available in bulk packaging. Packaging selection should align with your procurement and handling requirements.

Q: Are there any operating temperature or current rating differences between the main part and substitutes? A: The 75915-412 does not specify operating temperature or current ratings. The 75915-412LF similarly does not specify these parameters. The 3M 929974-01-12 specifies -40°C to 105°C operating temperature and 2A current rating. If your application requires specific thermal or current performance, verify these parameters against your design requirements.
