Amphenol ICC 76308-142 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76308-142 is a 42-position receptacle connector featuring 0.100" (2.54mm) pitch through-hole mounting with gold-plated mating contacts. This connector is part of the BergCon® series and is designed for board-to-board or cable applications. The product status is obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76308-142 receptacle connector is constrained by the following critical parameters:

• Pitch Compatibility: Mating pitch of 0.100" (2.54mm) is mandatory for mechanical and electrical interchangeability
• Contact Configuration: 42-position female socket receptacle with gold-plated mating contacts
• Mounting Interface: Through-hole solder termination on printed circuit boards
• Connector Series: BergCon® or equivalent rectangular connector family
• Electrical Performance: Gold contact finish at 30.0µin (0.76µm) thickness for reliable signal transmission

The substitute part 77311-101-36LF is a header connector from the BERGSTIK® series with 36 positions and 0.100" (2.54mm) pitch. This part shares the same pitch specification and through-hole mounting methodology but differs in connector type (header vs. receptacle) and position count (36 vs. 42). Substitution requires system-level evaluation of position requirements and mating interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 76308-142 is classified as obsolete, necessitating evaluation of active alternatives for new designs or system maintenance. The substitute part 77311-101-36LF offers the following advantages:

• Active Product Status: Currently manufactured and supported by Amphenol ICC, ensuring long-term availability and supply chain stability
• RoHS3 Compliance: Meets current environmental and regulatory requirements, whereas the main part is RoHS non-compliant
• Identical Pitch and Mounting: 0.100" (2.54mm) pitch and through-hole solder termination provide mechanical compatibility
• Equivalent Contact Specifications: Gold-plated mating contacts with identical finish thickness (30.0µin) and tin-plated posts ensure electrical performance parity

Critical consideration: The substitute part is a header connector with 36 positions versus the 42-position receptacle configuration of the main part. System designs must accommodate this position reduction and the change from receptacle to header connector type. Both parts share identical contact finish specifications, flammability ratings, and moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Can the 77311-101-36LF directly replace the 76308-142 in existing assemblies?

A: Direct replacement requires verification of two factors: (1) the system design must accommodate 36 positions instead of 42, and (2) the mating interface must be compatible with a header connector (male pins) rather than a receptacle connector (female sockets). Pitch compatibility at 0.100" (2.54mm) is maintained.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is governed by mating pitch (0.100" / 2.54mm), through-hole mounting methodology, solder termination, contact finish specifications (gold at 30.0µin mating, tin at 78.7µin post), and connector series compatibility within the Amphenol ICC rectangular connector family.

Q: Why is the 76308-142 listed as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production. The 77311-101-36LF, as an active product, represents the current manufacturing alternative within the Amphenol ICC connector portfolio.

Q: Are there electrical performance differences between these connectors?

A: Both connectors feature identical contact finish specifications and flammability ratings (UL94 V-0). The 77311-101-36LF provides specified operating temperature range (-65°C ~ 125°C) and current rating (3A per contact), whereas the main part does not specify these parameters.

Q: What is the significance of RoHS compliance in this substitution?

A: The 76308-142 is RoHS non-compliant, while the 77311-101-36LF is ROHS3 compliant. For applications subject to environmental regulations or customer requirements, the substitute part meets current compliance standards.

Q: How do the insulation materials differ?

A: The main part uses thermoplastic polyester with glass filling, while the substitute uses thermoplastic material. Both achieve UL94 V-0 flammability rating.
