Amphenol ICC 71609-320 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71609-320 is a 40-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 and tin-plated posts with push-pull fastening. The product is currently obsolete, making identification of suitable alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71609-320 is determined by the following critical parameters: connector type (receptacle), contact type (female socket), mating pitch (0.100"), contact finish specifications (gold mating, tin post), fastening type (push-pull), and series compatibility (Dubox™).

71609-320LF qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and compliance: 71609-320LF is active and RoHS compliant, whereas the original 71609-320 is obsolete and RoHS non-compliant.

71920-306LF does not qualify as a functional substitute. While it shares the same series (Dubox™), mating pitch (0.100"), contact materials, and finish specifications, it differs fundamentally in position count (6 vs. 40), row configuration (1 vs. 2), and mounting type (through-hole vs. surface mount, right-angle). These differences preclude direct substitution.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of 71609-320: Use 71609-320LF. This part maintains identical electrical and mechanical specifications while offering the advantage of active product status and RoHS compliance. The transition from obsolete to active status ensures long-term availability and supply chain stability. Both parts are packaged in tubes and share the same base product number (71609), confirming functional equivalence.

For new designs or systems requiring 40-position, 0.100" pitch surface-mount connectors: 71609-320LF is the appropriate selection, as it provides current manufacturing support and regulatory compliance.

71920-306LF is not suitable for substitution due to fundamental differences in position count, row configuration, and mounting technology. Selection of this part would require complete redesign of the connector interface.

Frequently Asked Questions (FAQ)

Q: Can 71609-320LF be used as a direct replacement for 71609-320 in existing assemblies?

A: Yes. The 71609-320LF maintains identical contact count (40 positions), pitch (0.100"), row spacing (0.100"), mounting configuration (surface mount, right-angle), contact finishes (gold mating, tin post), and fastening type (push-pull). Mechanical and electrical compatibility is confirmed.

Q: What is the primary difference between 71609-320 and 71609-320LF?

A: The 71609-320LF is the active production variant with RoHS compliance and tube packaging, while 71609-320 is obsolete and RoHS non-compliant. Both parts are functionally equivalent.

Q: Why is 71920-306LF listed but not recommended as a substitute?

A: The 71920-306LF differs in critical parameters: it provides only 6 positions (versus 40), uses a single-row configuration (versus 2 rows), and employs through-hole mounting (versus surface mount, right-angle). These differences make it incompatible with applications designed for the 71609-320.

Q: Are there any compliance or regulatory considerations when switching from 71609-320 to 71609-320LF?

A: Yes. The 71609-320LF is RoHS compliant and REACH affected, whereas the original 71609-320 is RoHS non-compliant and REACH unaffected. For applications subject to RoHS regulations, 71609-320LF is the required choice.

Q: What is the packaging difference between these parts?

A: The 71609-320 packaging is not specified in available data. The 71609-320LF is supplied in tube packaging. Confirm packaging requirements with your procurement specification.
