Amphenol ICC 75915-304 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75915-304 is a 4-position receptacle connector with 0.100" (2.54mm) pitch designed for through-hole PCB mounting. This connector features gold-plated mating contacts, tin-plated posts, and a push-pull fastening mechanism. The part is currently active in production with 657 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same connector category, allowing for design flexibility, supply chain optimization, or inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 75915-304 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type & Position Count: Receptacle configuration with 4 positions
• Pitch Specification: 0.100" (2.54mm) mating pitch for board-to-board compatibility
• Contact Configuration: Female socket contacts with gold mating finish
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Insulation Geometry: Matching insulation height of 0.335" (8.51mm)
• Material Standards: UL94 V-0 flammability rating

The identified substitutes maintain these core parameters while allowing for variations in secondary attributes such as insulation material composition, contact post finish thickness, and manufacturer-specific design features.

Engineering Selection Recommendations

75915-304LF (Direct Amphenol ICC Variant)

The 75915-304LF is a direct variant of the main part number, maintaining identical mechanical and electrical specifications within the Dubox™ series. The primary distinction is RoHS compliance status. Selection of this part is appropriate when RoHS-compliant components are required for the application or supply chain. Inventory availability is higher at 1008 units.

215299-4 (TE Connectivity Cross-Reference)

The 215299-4 from TE Connectivity AMPMODU HV-100 series provides functional equivalence with the following considerations:

• Contact post length is 0.122" (3.10mm) versus 0.114" (2.90mm) on the Amphenol parts, resulting in 0.008" additional mating height
• Insulation material differs (polyester versus thermoplastic), both glass-filled and UL94 V-0 rated
• Termination includes kinked pin option in addition to solder
• RoHS compliant with higher inventory availability (4518 units)

This part is suitable for applications where the increased post length and alternative insulation material do not create mechanical or thermal constraints. The kinked pin termination provides enhanced mechanical retention during PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can 75915-304LF be used as a direct replacement for 75915-304?

A: Yes. Both parts maintain identical mechanical dimensions, pitch, contact configuration, and electrical characteristics. The difference is RoHS compliance status. The 75915-304LF is RoHS compliant while the 75915-304 is not. Selection depends on application requirements and regulatory compliance needs.

Q: What is the impact of the 0.008" difference in contact post length between Amphenol and TE Connectivity parts?

A: The 215299-4 has a contact post length of 0.122" compared to 0.114" on the 75915-304 and 75915-304LF. This results in approximately 0.008" additional mating height. This difference must be evaluated against PCB stack-up, mating connector depth, and mechanical clearance requirements in the specific application.

Q: Are all three parts mechanically interchangeable?

A: The 75915-304 and 75915-304LF are fully mechanically interchangeable. The 215299-4 is functionally compatible but has a longer contact post. Mechanical interchangeability depends on the mating connector and available PCB depth. Verification against the mating plug connector specifications is required.

Q: What are the compliance differences between these parts?

A: The 75915-304 is RoHS non-compliant. Both 75915-304LF and 215299-4 are RoHS compliant. All three parts meet UL94 V-0 flammability requirements. Selection should align with end-product regulatory requirements and customer specifications.

Q: Which part should be selected for new designs?

A: For new designs, either 75915-304LF (Amphenol, RoHS compliant) or 215299-4 (TE Connectivity, RoHS compliant, higher inventory) are appropriate. The 75915-304 should be reserved for legacy designs or applications where RoHS compliance is not required. The choice between LF and 215299-4 depends on preferred supplier, inventory availability, and mechanical constraints related to contact post length.
