Amphenol ICC 76342-406 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76342-406 is a 12-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications. This connector features through-hole solder termination, tin-lead contact finish, and is rated UL94 V-0 for flammability. The part is currently obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76342-406 is based on maintaining electrical and mechanical compatibility through identical core parameters: connector type (receptacle), position count (12), mating pitch (0.100"), row configuration (2 rows with 0.100" spacing), mounting method (through hole), termination type (solder), fastening mechanism (push-pull), insulation material (thermoplastic, glass filled), and flammability rating (UL94 V-0). The primary distinction between the main part and its substitute lies in contact finish specification and product status. The 76342-406 uses tin-lead contact finish and is obsolete, while the substitute maintains functional equivalence with a modified contact finish and active product status.

Parameter Comparison

Engineering Selection Recommendations

The 76342-406LF serves as the direct active equivalent to the obsolete 76342-406. Both connectors maintain identical mechanical and electrical specifications within the Dubox™ series, including 12-position configuration, 0.100" pitch, through-hole solder termination, and UL94 V-0 flammability rating. The primary differences are contact finish composition (tin-lead versus tin) and regulatory compliance status. The 76342-406LF is RoHS compliant and REACH affected, whereas the original part is RoHS non-compliant and REACH unaffected. For new designs and production applications, the 76342-406LF is the appropriate selection due to its active product status and modern regulatory compliance. For legacy system maintenance where tin-lead contact finish is specifically required, the original 76342-406 remains available in existing inventory.

Frequently Asked Questions (FAQ)

Q: Can the 76342-406LF directly replace the 76342-406 in existing designs?

A: Yes. Both connectors share identical mechanical dimensions, pitch specifications, mounting configuration, and electrical characteristics. The primary difference is contact finish composition and regulatory compliance status. The 76342-406LF is the active production equivalent.

Q: What is the significance of the contact finish change from tin-lead to tin?

A: The contact finish change reflects RoHS compliance requirements. Both finishes maintain the same thickness (78.7µin / 2.00µm) and provide equivalent electrical performance. The tin finish in the 76342-406LF eliminates lead content while preserving contact reliability.

Q: Are there packaging differences between these parts?

A: The 76342-406 packaging is not specified in available data. The 76342-406LF is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Why is the original 76342-406 listed as obsolete?

A: The 76342-406 is obsolete due to regulatory evolution toward RoHS compliance. The 76342-406LF represents the current production equivalent within the same Dubox™ series.

Q: What applications are these connectors suitable for?

A: Both connectors are specified for automotive, general purpose, industrial, and telecommunications applications.

Q: Is the 76342-406LF compatible with existing mating connectors designed for the 76342-406?

A: Yes. Mating compatibility is determined by pitch (0.100"), position count (12), row configuration (2 rows), and fastening type (push-pull), all of which are identical between the two parts.
