Amphenol ICC 71609-313 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71609-313 is a 26-position receptacle connector with 0.100" (2.54mm) pitch, designed for surface mount, right-angle board-to-board applications. This connector features gold-plated mating contacts, push-pull fastening, and is part of the Dubox™ series. The part is currently listed as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the 71609-313 is determined by the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (26), pitch (0.100"), number of rows (2), row spacing (0.100"), mounting type (surface mount, right angle), style (board to board), contact finish (gold), and insulation material (thermoplastic, glass filled).

The substitute parts identified are:

71609-313LF — Direct equivalent with identical electrical and mechanical specifications. The primary distinction is product status: 71609-313LF is active, whereas 71609-313 is obsolete. Both share the same base product number (71609), series designation (Dubox™), and all critical mating parameters. The LF suffix indicates RoHS compliance, representing the modern production variant.

71918-264LF — This part shares the same pitch (0.100"), row spacing (0.100"), contact material (phosphor bronze), contact finish (gold with 30.0µin thickness), insulation material (thermoplastic, glass filled), and flammability rating (UL94 V-0). However, it differs in connector type (header vs. receptacle), contact type (male pin vs. female socket), number of positions (64 vs. 26), mounting type (through hole vs. surface mount), and style (board to cable/wire vs. board to board). This part is not a direct substitute due to fundamental connector architecture differences.

Engineering Selection Recommendations

For direct replacement: Use 71609-313LF. This part maintains identical electrical and mechanical specifications to the 71609-313 while offering active product status and RoHS compliance. The LF designation confirms lead-free manufacturing and modern regulatory alignment.

For alternative applications: The 71918-264LF is not suitable as a direct substitute due to fundamental differences in connector architecture (header vs. receptacle), contact gender (male vs. female), position count (64 vs. 26), and mounting methodology (through hole vs. surface mount). Selection of this part requires complete circuit redesign and PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can 71609-313LF be used as a direct replacement for 71609-313?

A: Yes. Both parts share identical connector type, contact type, position count, pitch, row spacing, mounting type, style, contact finish specifications, and insulation material. The primary difference is product status and RoHS compliance. 71609-313LF is the active production equivalent.

Q: Why is 71918-264LF listed as a substitute if it has different specifications?

A: 71918-264LF shares common pitch, row spacing, contact material, contact finish thickness, insulation material, and flammability rating. However, it is fundamentally different in connector type, contact gender, position count, mounting type, and application style. This part is not interchangeable without complete design modification.

Q: What does the LF suffix indicate?

A: The LF suffix denotes lead-free manufacturing and RoHS compliance, representing the modern production variant of the base product number.

Q: Are there mechanical compatibility concerns between 71609-313 and 71609-313LF?

A: No. Both parts maintain identical mechanical dimensions, including insulation height (0.230"), pitch (0.100"), and row spacing (0.100").

Q: What is the significance of the Dubox™ series designation?

A: Dubox™ is the product series identifier for the 71609 base product number. Both 71609-313 and 71609-313LF belong to this series.
