Amphenol ICC 71609-310 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71609-310 is a 20-position receptacle connector with 0.100" (2.54mm) pitch, designed for surface mount, right-angle board-to-board applications. This part is classified as obsolete, making identification of suitable alternatives essential for ongoing production and maintenance requirements. The connector features gold-plated mating contacts, tin-plated posts, and is constructed from thermoplastic glass-filled insulation material rated UL94 V-0.

Substitute Part Grouping Explanation

Substitution for the 71609-310 is determined by strict alignment with the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (20), mating pitch (0.100"), number of rows (2), row spacing (0.100"), mounting type (surface mount, right angle), and board-to-board style. Contact finish specifications (gold mating, tin post) and insulation material properties must also match.

The substitute parts identified are:

71609-310LF — Direct equivalent with identical electrical and mechanical specifications. Differs only in product status (active vs. obsolete) and RoHS compliance status.

71918-250LF — Partial compatibility. While this part shares the same mating pitch (0.100"), row spacing (0.100"), and contact materials, it is a header connector (male pin, through-hole mounted) with 50 positions and board-to-cable/wire style, making it unsuitable as a direct substitute for the 71609-310 receptacle application.

Engineering Selection Recommendations

71609-310LF is the appropriate substitute for the obsolete 71609-310. Both parts are functionally and mechanically identical, with matching connector type, contact configuration, pitch, mounting method, and insulation properties. The primary distinction is product status: 71609-310LF is active and RoHS compliant, whereas the original part is obsolete and RoHS non-compliant. Selection of 71609-310LF eliminates supply chain risk associated with obsolete inventory while meeting current regulatory compliance requirements.

71918-250LF is not suitable as a substitute. Despite sharing common pitch and row spacing parameters, it is a fundamentally different connector type (header vs. receptacle), contact gender (male vs. female), position count (50 vs. 20), mounting method (through-hole vs. surface mount), and application style (board-to-cable/wire vs. board-to-board). These differences preclude direct substitution in applications designed for the 71609-310.

Frequently Asked Questions (FAQ)

Q: Can 71609-310LF be used as a direct replacement for 71609-310?

A: Yes. The 71609-310LF is electrically and mechanically equivalent to the 71609-310. Both are 20-position receptacle connectors with identical pitch (0.100"), mounting type (surface mount, right angle), contact finish specifications, and insulation properties. The primary difference is product status and RoHS compliance.

Q: Why is 71918-250LF listed as a substitute if it cannot replace the 71609-310?

A: The 71918-250LF shares the same mating pitch (0.100") and row spacing (0.100"), which are common parameters across Amphenol ICC connector families. However, it is a header connector with male pins, 50 positions, and through-hole mounting, making it incompatible with applications requiring a 20-position surface-mount receptacle. It is included for reference only.

Q: What packaging differences exist between the main part and 71609-310LF?

A: The 71609-310 is supplied without specified packaging, while 71609-310LF is packaged in tubes. This packaging difference does not affect electrical or mechanical compatibility.

Q: Are there compliance considerations when substituting 71609-310 with 71609-310LF?

A: Yes. The 71609-310 is RoHS non-compliant, while 71609-310LF is RoHS compliant. Additionally, 71609-310LF is REACH affected, whereas the original part is REACH unaffected. These compliance differences should be evaluated against application and regulatory requirements.

Q: What is the inventory status for these parts?

A: The 71609-310 has 872 pieces in stock (obsolete status). The 71609-310LF has 1091 pieces in stock (active status). The 71918-250LF has 941 pieces in stock (active status).
