Amphenol ICC 76342-306 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76342-306 is a 12-position receptacle connector in the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The part is currently obsolete with 1155 units in stock. Due to its obsolete status, identifying equivalent and substitute parts is essential for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution for the 76342-306 is determined by strict alignment with the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (12), mating pitch (0.100"), number of rows (2), row spacing (0.100"), mounting type (through hole), termination method (solder), and fastening type (push-pull).

The primary direct substitute is the 76342-306LF, which maintains identical electrical and mechanical specifications while offering improved compliance status. The 77313-124-06LF represents a different connector category (header vs. receptacle) with reduced position count (6 vs. 12) and is not a direct functional equivalent; it is listed as a cross-reference only and does not meet the core substitution criteria for the 12-position receptacle application.

Engineering Selection Recommendations

The 76342-306LF is the direct equivalent for the obsolete 76342-306. Both parts share identical electrical and mechanical specifications, including 12-position configuration, 0.100" pitch, female socket contacts, and push-pull fastening. The primary distinction is product status: the 76342-306LF is active and offers superior compliance, being RoHS compliant and REACH affected, compared to the non-compliant status of the original part. The 76342-306LF is available in higher inventory (3466 units) and is packaged in tube format, supporting production continuity.

The 77313-124-06LF does not qualify as a direct substitute due to fundamental differences: it is a header connector with male pins rather than a receptacle with female sockets, and it provides only 6 positions instead of 12. This part cannot fulfill the functional requirements of the 76342-306 in board-to-board receptacle applications.

Frequently Asked Questions (FAQ)

Q: Can the 76342-306LF directly replace the 76342-306 in existing designs?

A: Yes. The 76342-306LF maintains identical electrical and mechanical specifications, including connector type, contact configuration, pitch, row spacing, mounting method, and termination. The parts are mechanically and electrically interchangeable.

Q: What is the significance of the "LF" suffix in the 76342-306LF part number?

A: The "LF" designation indicates lead-free compliance, reflecting the part's RoHS compliance status. This distinguishes it from the original 76342-306, which is RoHS non-compliant.

Q: Why is the 77313-124-06LF listed as a substitute if it has different specifications?

A: The 77313-124-06LF is listed as a cross-reference only and does not meet the substitution criteria for the 12-position receptacle application. It is included in the reference data but is not a functional equivalent due to its header connector type, male pin contacts, and 6-position configuration.

Q: What packaging options are available for the substitute parts?

A: The 76342-306LF is supplied in tube packaging, while the 77313-124-06LF is supplied in bulk packaging. Packaging selection should align with production and inventory management requirements.

Q: Are there compliance differences between the 76342-306 and 76342-306LF?

A: Yes. The 76342-306LF is RoHS compliant and REACH affected, whereas the original 76342-306 is RoHS non-compliant and REACH unaffected. For applications requiring regulatory compliance, the 76342-306LF is the appropriate selection.
