Amphenol ICC 76342-407 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76342-407 is a 14-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, making identification of suitable substitutes necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76342-407 is determined by the following critical parameters that must remain constant:

• Connector Type & Style: Receptacle, board-to-board configuration
• Position Count & Arrangement: 14 positions in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull connector system
• Series Compatibility: Dubox™ series

The primary substitute identified is the 76342-407LF, which maintains all critical mechanical and electrical parameters while differing in contact finish composition and product status.

Parameter Comparison

Engineering Selection Recommendations

The 76342-407LF serves as the direct active substitute for the obsolete 76342-407. Both connectors maintain identical mechanical dimensions, pitch specifications, and contact geometry, ensuring direct form-fit-function compatibility in board-to-board applications.

The primary distinction between these parts is the contact finish composition. The 76342-407 uses tin-lead plating, while the 76342-407LF uses tin plating. This difference reflects regulatory compliance evolution: the 76342-407LF is RoHS compliant and REACH affected, whereas the original part is RoHS non-compliant and REACH unaffected.

For new designs and ongoing system support where the original 76342-407 is no longer available, the 76342-407LF is the appropriate selection. The active product status of the 76342-407LF ensures continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 76342-407LF directly replace the 76342-407 in existing assemblies?

A: Yes. Both connectors share identical mechanical specifications, pitch, row spacing, mounting type, and termination method. The contact finish difference (tin-lead versus tin) does not affect mechanical compatibility or mating performance.

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

A: The tin finish in the 76342-407LF reflects compliance with RoHS regulations, which restrict lead content in electronic components. The tin plating maintains equivalent electrical and mechanical performance while meeting modern regulatory requirements.

Q: Are there packaging differences between these parts?

A: The 76342-407LF is supplied in tube packaging, while packaging information for the 76342-407 is not specified in the available data. This affects ordering and handling but does not impact connector functionality.

Q: What applications are these connectors suitable for?

A: Both connectors are specified for automotive, general purpose, industrial, and telecommunications applications. The UL94 V-0 flammability rating supports use in safety-critical environments.

Q: Why is the 76342-407 listed as obsolete?

A: The original part has been superseded by the 76342-407LF, which offers the same functionality with improved regulatory compliance. Amphenol ICC has transitioned to the lead-free variant for ongoing production and support.
