Amphenol ICC 76350-104-04 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76350-104-04 is a through-hole, right-angle rectangular connector header with 4 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This BERGSTIK® series component features male pins with gold-plated mating contacts and phosphor bronze construction. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from both Amphenol ICC and Samtec Inc. provide direct functional replacement with improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Connector type (Header), contact type (Male Pin), and style (Board to Board)
Position count (4) and row configuration (2 rows)
Pitch specifications: mating pitch 0.100" (2.54mm) and row spacing 0.100" (2.54mm)
Mounting configuration: through-hole, right-angle orientation
Termination method: solder
Fastening mechanism: push-pull
Contact length for mating: 0.230" (5.84mm)
Material flammability: UL94 V-0
Insulation color: black
MSL rating: 1 (Unlimited)

The substitute parts listed maintain these core parameters. Variations in contact finish (gold, tin), contact finish thickness, insulation material composition (thermoplastic vs. PBT), and operating temperature ranges do not affect functional interchangeability for standard board-to-board applications.

Engineering Selection Recommendations

Primary Substitute: 76350-104-04LF

The 76350-104-04LF is the direct equivalent from Amphenol ICC, maintaining identical electrical and mechanical specifications while offering active product status and RoHS compliance. This part is recommended for applications requiring minimal design validation and maximum compatibility assurance.

Alternative Substitutes: Samtec TSW-102-08 Series

The Samtec TSW-102-08-G-D-RA, TSW-102-08-L-D-RA, TSW-102-08-S-D-RA, and TSW-102-08-T-D-RA connectors provide functional equivalence with extended operating temperature ranges (-55°C to 125°C for most variants) and ROHS3 compliance. These parts are suitable for applications where broader temperature performance or enhanced regulatory compliance is required.

Contact Finish Considerations:

TSW-102-08-G-D-RA: Gold mating contact with 10.0µin thickness and gold post finish
TSW-102-08-L-D-RA: Gold mating contact with 10.0µin thickness and tin post finish
TSW-102-08-S-D-RA: Gold mating contact with 30.0µin thickness and tin post finish
TSW-102-08-T-D-RA: Tin mating contact and tin post finish

Selection among Samtec variants depends on specific contact finish requirements and post-plating specifications for your application.

Frequently Asked Questions (FAQ)

Q: Can I use 76350-104-04LF as a direct replacement for the obsolete 76350-104-04?

A: Yes. The 76350-104-04LF maintains identical pitch (0.100" / 2.54mm), position count (4 positions in 2 rows), mounting type (through-hole right-angle), contact length (0.230"), and all other critical mechanical and electrical parameters. The primary difference is active product status and RoHS compliance.

Q: What are the key differences between Amphenol ICC and Samtec substitutes?

A: Both manufacturers provide 4-position, 2-row headers with 0.100" pitch and right-angle through-hole mounting. Samtec TSW-102-08 variants offer extended operating temperature ranges (-55°C to 125°C or -55°C to 105°C) compared to the original part's unspecified range. Contact finish options vary across Samtec variants, allowing selection based on specific post-plating and mating contact requirements.

Q: Are all listed substitutes mechanically interchangeable?

A: Yes. All listed parts share identical mating pitch (0.100"), row spacing (0.100"), contact length for mating (0.230"), mounting configuration (through-hole right-angle), and termination method (solder). Mechanical interchangeability is assured across all variants.

Q: Does contact finish thickness affect compatibility?

A: Contact finish thickness variations (10.0µin vs. 30.0µin for gold finishes) do not affect mechanical or electrical interchangeability. Selection should be based on application-specific requirements for contact durability and mating cycles.

Q: Which substitute offers the best compliance profile?

A: The 76350-104-04LF and all Samtec TSW-102-08 variants are RoHS compliant (RoHS or ROHS3). The original 76350-104-04 is RoHS non-compliant. For applications requiring regulatory compliance, any of the active substitutes are suitable.

Q: Can I mix contact finish types in the same application?

A: All listed parts maintain UL94 V-0 flammability rating, phosphor bronze contact material, and identical mechanical dimensions. Contact finish compatibility depends on your specific mating connector specifications and application requirements.

Q: What is the difference between gold and tin contact finishes?

A: Both finishes are provided on phosphor bronze contacts. Gold finishes (GXT™ or standard gold) offer enhanced corrosion resistance. Tin finishes provide cost efficiency. Selection depends on environmental exposure and contact durability requirements specified in your application.
