Amphenol ICC 76357-401 Socket Contact Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76357-401 is a socket contact for rectangular connectors designed for wire gauges 22-30 AWG with crimp termination and tin-lead finish. This component is part of the DUBOX™, MezzSelect™, and Basics+ series. The part is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76357-401 is determined by the following critical parameters:

• Contact Type: Socket configuration
• Termination Method: Crimp connection
• Wire Gauge Compatibility: 22-30 AWG range
• Series Compatibility: DUBOX™, MezzSelect™, Basics+ family
• Base Product Number: 76357 designation

Two substitute parts are identified:

1. 76357-401LF - Direct series continuation with updated finish specification
2. 77315-824-36LF - Alternative connector from the same manufacturer within compatible rectangular connector category

Parameter Comparison

Engineering Selection Recommendations

76357-401LF is the primary substitute for 76357-401. Both components share the same base product number (76357), socket configuration, crimp termination, and 22-30 AWG wire gauge specification. The 76357-401LF is an active product with RoHS compliance and REACH affected status, making it suitable for new designs and legacy replacements where regulatory compliance is required. The contact finish differs (tin versus tin-lead), with 76357-401LF providing a thinner finish layer (78.7µin versus 196.9µin).

77315-824-36LF represents an alternative from the same manufacturer within the rectangular connector category. However, this part operates as a male pin header with solder termination and 36-position configuration, differing fundamentally from the socket crimp contact specification of the main part. This substitute is applicable only in applications where connector topology and termination method can be redesigned.

For direct replacement in existing assemblies designed for 76357-401, 76357-401LF is the appropriate selection. For new designs or applications permitting connector architecture changes, 77315-824-36LF offers an active alternative from the same manufacturer.

Frequently Asked Questions (FAQ)

Q: Can 76357-401LF directly replace 76357-401 in existing designs?

A: Yes. Both parts are socket contacts with crimp termination for 22-30 AWG wire. The primary difference is contact finish composition (tin versus tin-lead) and finish thickness. Electrical and mechanical compatibility is maintained within the DUBOX™, MezzSelect™, and Basics+ series framework.

Q: What is the significance of the "LF" designation in 76357-401LF?

A: The "LF" suffix indicates lead-free composition, reflecting RoHS compliance. This part is suitable for applications requiring regulatory compliance with modern environmental standards.

Q: Is 77315-824-36LF compatible with applications designed for 76357-401?

A: No direct compatibility exists. The 77315-824-36LF is a male pin header with solder termination and 36-position configuration, whereas 76357-401 is a socket contact with crimp termination. Substitution requires redesign of the connector interface and termination methodology.

Q: What are the packaging differences between these parts?

A: 76357-401 packaging is not specified in available data. Both 76357-401LF and 77315-824-36LF are supplied in bulk packaging.

Q: Are there compliance considerations when substituting 76357-401 with 76357-401LF?

A: Yes. The original 76357-401 is RoHS non-compliant, while 76357-401LF is RoHS compliant. Applications subject to RoHS regulations must use 76357-401LF. Both parts are REACH affected or unaffected as specified in the parameter comparison table.

Q: What wire gauge range is supported by these socket contacts?

A: Both 76357-401 and 76357-401LF support 22-30 AWG wire gauges. The 77315-824-36LF is a header connector and does not use wire gauge specifications.
