75860-101LF DIN Backplane Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The 75860-101LF is a 96-position DIN connector receptacle manufactured by Amphenol ICC (FCI) in the Quickie™ series. This panel mount, female socket connector features gold plating and IDC termination, designed for backplane applications requiring reliable signal and power distribution. The part is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible interconnect solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the 75860-101LF is determined by strict alignment with the following critical parameters:

Connector configuration: 96-position receptacle with female sockets
Position loading: 64 positions loaded
Pitch and row structure: 0.100" (2.54mm) pitch, 3-row arrangement
Termination method: IDC (Insulation Displacement Contact)
Contact material: Gold plating
Operating environment: -55°C to 125°C temperature range
Flammability compliance: UL94 V-0 rating

Two substitute parts meet these criteria with documented compatibility:

167257-5 (TE Connectivity AMP Connectors, Eurocard series) qualifies as a direct functional substitute with panel mount configuration matching the original application.

746603-4 (TE Connectivity AMP Connectors, Eurocard series) qualifies as a substitute with identical electrical and mechanical specifications but differs in mounting type (free hanging/in-line versus panel mount), requiring mechanical redesign consideration.

Engineering Selection Recommendations

167257-5 is the primary substitute for direct replacement applications. This part maintains identical mounting configuration (panel mount), electrical specifications, and environmental ratings as the original 75860-101LF. The part is active in production with RoHS compliance certification, ensuring long-term availability and regulatory alignment for new designs.

746603-4 provides electrical and thermal equivalence but requires mechanical redesign due to its free hanging (in-line) mounting configuration. This part is suitable only for applications where the mounting interface can be modified to accommodate in-line termination. The part carries ROHS3 compliance and is actively manufactured.

Both substitutes operate within the identical temperature range (-55°C to 125°C) and maintain UL94 V-0 flammability compliance. Contact finish thickness variations (39.4µin original versus 31.5µin and 30.0µin for substitutes) remain within acceptable ranges for gold-plated connector applications.

Frequently Asked Questions (FAQ)

Q: Can 167257-5 be used as a direct drop-in replacement for 75860-101LF?

A: Yes. The 167257-5 maintains identical position count (96 positions, 64 loaded), pitch (0.100"), row configuration (3 rows), panel mount orientation, and IDC termination. Electrical and thermal specifications are equivalent.

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

A: Both parts share identical electrical and thermal characteristics. The primary difference is mounting type: 167257-5 is panel mount (matching the original), while 746603-4 is free hanging (in-line). Selection depends on the mechanical interface requirements of your application.

Q: Are the substitute parts RoHS compliant?

A: Yes. 167257-5 is RoHS Compliant, and 746603-4 is ROHS3 Compliant. Both meet current regulatory requirements for electronic component manufacturing.

Q: Does the reduced contact finish thickness on substitute parts affect performance?

A: The contact finish thickness reduction (from 39.4µin to 31.5µin or 30.0µin) remains within acceptable engineering tolerances for gold-plated connectors in standard backplane applications. All parts maintain equivalent electrical conductivity and corrosion resistance.

Q: What is the current inventory status of these substitutes?

A: 167257-5 has 790 pieces in stock. 746603-4 has 1230 pieces in stock. Both are actively manufactured by TE Connectivity AMP Connectors.

Q: Are there any temperature or environmental limitations with the substitute parts?

A: No. All three parts operate identically across the -55°C to 125°C range and maintain UL94 V-0 flammability compliance. Moisture sensitivity level is equivalent (MSL 1 - Unlimited).
