Amphenol ICC 75915-418 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75915-418 is an 18-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 part of the Dubox™ series. The part is currently obsolete, making identification of suitable substitutes essential for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 75915-418 is determined by the following critical parameters that must remain consistent:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 18 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Electrical & Mechanical Compatibility: Board-to-board style with matching insulation height and contact geometry
• Flammability Compliance: UL94 V-0 material rating

The substitute parts identified maintain these core parameters while differing in contact finish composition, insulation material formulation, or regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

75915-418LF (Direct Amphenol ICC Substitute)

The 75915-418LF is the primary substitute for the obsolete 75915-418. Both connectors are from the same manufacturer (Amphenol ICC) and Dubox™ series, with identical mechanical dimensions, pitch, and position count. The 75915-418LF maintains the same insulation height (0.335"), contact length (0.114"), and phosphor bronze contact material. The primary difference is the contact finish composition: 75915-418LF uses tin finish instead of tin-lead. The 75915-418LF holds active product status and is RoHS compliant, making it suitable for new designs and legacy system replacements where regulatory compliance is required.

929974-01-18 (3M Manufacturer Recommended Substitute)

The 929974-01-18 from 3M is an alternative substitute that maintains the 18-position, 0.100" pitch configuration and push-pull fastening. This connector is from the 929 series and features forked contact geometry rather than socket contacts. The 929974-01-18 provides specified electrical ratings (2A current, 1500V voltage) and operating temperature range (-40°C ~ 105°C), which are not documented for the main part. The insulation material differs (PCT vs. thermoplastic), and the insulation height is slightly reduced (0.325" vs. 0.335"). The contact post length is longer (0.125" vs. 0.114"), and contact finish thickness is greater (100.0µin vs. 78.7µin). This part is active and RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can the 75915-418LF directly replace the 75915-418 in existing designs?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing, position count, and mounting configuration. The primary difference is the contact finish (tin vs. tin-lead), which does not affect mechanical compatibility or board-level interconnection. The 75915-418LF is the recommended direct replacement for obsolete stock.

Q: What is the difference between the Amphenol ICC 75915-418LF and the 3M 929974-01-18?

A: Both are 18-position, 0.100" pitch receptacle connectors with through-hole solder termination. Key differences include: contact geometry (socket vs. forked), insulation material (thermoplastic vs. PCT), insulation height (0.335" vs. 0.325"), contact post length (0.114" vs. 0.125"), and contact finish thickness (78.7µin vs. 100.0µin). The 929974-01-18 provides specified electrical ratings and operating temperature range, while the 75915-418LF maintains closer dimensional alignment with the original part.

Q: Is the 75915-418LF RoHS compliant?

A: Yes. The 75915-418LF is RoHS compliant, whereas the original 75915-418 is RoHS non-compliant. This makes the 75915-418LF suitable for applications requiring regulatory compliance with lead-free or restricted substance requirements.

Q: What packaging options are available for these substitutes?

A: The 75915-418LF is supplied in tube packaging. The 929974-01-18 is supplied in bulk packaging. Packaging selection should be based on procurement volume and handling requirements for your assembly process.

Q: Are there mechanical compatibility concerns when switching between these substitutes?

A: The 75915-418LF maintains identical mechanical dimensions to the original part. The 929974-01-18 has minor dimensional variations: insulation height is 0.010" shorter, and contact post length is 0.011" longer. These variations may affect mating force characteristics and board-level clearance in space-constrained applications. Verify mechanical fit in your specific application before production transition.

Q: Which substitute should be selected for new designs?

A: Selection depends on regulatory and performance requirements. For designs requiring RoHS compliance and closest dimensional match to legacy systems, select 75915-418LF. For applications requiring specified electrical ratings and extended operating temperature range, select 929974-01-18, with verification of mechanical fit in your assembly.
