Equivalent & Substitute Parts for 75860-101

Part Overview

The 75860-101 is a 96-position DIN connector receptacle manufactured by Amphenol ICC (FCI). This backplane connector features female sockets with gold plating, free hanging (in-line) mounting, and IDC termination. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution for the 75860-101 is determined by strict equivalence across the following critical parameters:

Connector type: Receptacle, female sockets
Position count: 96 positions with 64 positions loaded
Pitch: 0.100" (2.54mm)
Row configuration: 3 rows, Style C
Mounting classification: Free hanging (in-line)
Termination method: IDC
Contact finish: Gold plating
Operating temperature range: -55°C ~ 125°C
Flammability rating: UL94 V-0
Insulation material: Polyester thermoplastic

The substitute part 746603-4 (TE Connectivity AMP Connectors) meets all these criteria and is classified as active product status, making it the direct functional equivalent for the obsolete 75860-101.

The part 167257-5 shares the same core electrical and mechanical specifications but differs in mounting type (panel mount versus free hanging), making it suitable only for applications where panel mounting is acceptable.

Engineering Selection Recommendations

For applications currently using the obsolete 75860-101, the 746603-4 (TE Connectivity AMP Connectors) is the primary substitute. This part maintains identical mounting configuration (free hanging in-line), electrical specifications, and mechanical dimensions. The 746603-4 is active product status with ROHS3 compliance, providing long-term availability and regulatory alignment.

The 167257-5 is suitable only when system redesign permits panel mount installation. While electrically and mechanically equivalent in all other respects, the different mounting type requires mechanical redesign of the host assembly.

Both substitute parts feature glass-filled polyester thermoplastic insulation, which provides enhanced material properties compared to the original part's standard polyester thermoplastic formulation.

Frequently Asked Questions (FAQ)

Q: Can 746603-4 be used as a direct replacement for 75860-101 without modification?

A: Yes. The 746603-4 matches all critical parameters: 96-position receptacle, 64 positions loaded, 0.100" pitch, 3-row configuration, free hanging in-line mounting, IDC termination, gold contact finish, and identical operating temperature range. No mechanical or electrical redesign is required.

Q: What is the key difference between 746603-4 and 167257-5?

A: The mounting type differs. The 746603-4 is free hanging (in-line), matching the original 75860-101 configuration. The 167257-5 is panel mount and requires mechanical redesign of the host assembly to accommodate the different mounting interface.

Q: Are there compliance differences between the original part and substitutes?

A: Yes. The 75860-101 is RoHS non-compliant. Both substitute parts (746603-4 and 167257-5) are RoHS compliant, meeting current regulatory requirements for new designs and production.

Q: Do the substitute parts have the same contact finish specifications?

A: Both substitute parts feature gold plating with specified thickness values (30.0µin to 31.5µin), whereas the original part does not specify contact finish thickness. The gold finish composition and performance are equivalent across all three parts.

Q: What is the packaging difference for 746603-4?

A: The 746603-4 is supplied in tray packaging, whereas the original 75860-101 packaging is not specified. This affects handling and storage but does not impact electrical or mechanical performance.
