Amphenol ICC 93932-444HLF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 93932-444HLF is a through-hole, right-angle rectangular connector header with 44 positions at 0.100" (2.54mm) pitch, configured as a 2-row board-to-board interface. This connector is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The BERGSTIK® II series connector provides solder termination with push-pull fastening and unshrouded design suitable for standard PCB applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 93932-444HLF are qualified based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 44 positions in 2-row arrangement
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Fastening Mechanism: Push-pull fastening system
• Electrical & Mechanical Envelope: Square contact shape, unshrouded design, UL94 V-0 flammability rating

The identified substitute parts maintain these core parameters while offering active product status and improved availability. Variations in contact finish, insulation material, and operating temperature ranges are secondary considerations that do not affect primary substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full functional compatibility with the 93932-444HLF based on core electrical and mechanical parameters. Selection between alternatives should be based on the following criteria:

3M 2344-5121-TG: Active product status with established supply chain. Gold-plated mating contacts provide enhanced corrosion resistance compared to tin finish. Operating temperature range of -55°C to 105°C covers standard industrial applications. RoHS non-compliant status requires verification against regulatory requirements for the end application.

Samtec Inc. TSW-122-08-L-D-NA: Active product with ROHS3 compliance, suitable for applications with RoHS mandates. Extended operating temperature range of -55°C to 125°C accommodates higher thermal environments. PBT insulation material with glass reinforcement provides improved mechanical stability. Bulk packaging option supports high-volume procurement.

Both parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity rating, matching the original specification. The choice between these substitutes depends on regulatory compliance requirements, thermal operating conditions, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the 3M 2344-5121-TG or Samtec TSW-122-08-L-D-NA be used as direct replacements for the Amphenol ICC 93932-444HLF?

A: Yes. Both substitute parts maintain identical connector type, position count, row configuration, pitch spacing, mounting orientation, termination method, and fastening mechanism. The 44-position, 2-row, 0.100" pitch header configuration is fully compatible with existing PCB layouts and mating connectors designed for the original part.

Q: What are the differences in contact finish between the original and substitute parts?

A: The 93932-444HLF uses tin-plated mating contacts. The 3M 2344-5121-TG provides gold plating (10.0µin thickness), which offers superior corrosion resistance and lower contact resistance. The Samtec TSW-122-08-L-D-NA uses gold plating for mating contacts with tin post finish. Gold-plated contacts are generally preferred for applications requiring extended shelf life or exposure to corrosive environments.

Q: Are there compliance differences between the substitute parts?

A: The 3M 2344-5121-TG is RoHS non-compliant, while the Samtec TSW-122-08-L-D-NA is ROHS3 compliant. Applications subject to RoHS directives or customer requirements must use the Samtec part. Both parts carry UL94 V-0 flammability certification and are suitable for standard industrial applications.

Q: What is the operating temperature range for each part?

A: The 3M 2344-5121-TG operates from -55°C to 105°C. The Samtec TSW-122-08-L-D-NA operates from -55°C to 125°C. If the application requires operation above 105°C, the Samtec part is the appropriate selection.

Q: Do the substitute parts have the same insulation material as the original?

A: The original 93932-444HLF insulation material is not specified. The 3M 2344-5121-TG uses thermoplastic glass-filled material, while the Samtec TSW-122-08-L-D-NA uses polybutylene terephthalate (PBT). Both materials provide UL94 V-0 flammability rating and are standard for this connector class.

Q: What packaging options are available for the substitute parts?

A: The 3M 2344-5121-TG packaging is not specified in the data. The Samtec TSW-122-08-L-D-NA is available in bulk packaging, suitable for high-volume assembly operations.

Q: Are all 44 positions loaded on the substitute parts?

A: Yes. Both the 3M 2344-5121-TG and Samtec TSW-122-08-L-D-NA have all 44 positions loaded, matching the original 93932-444HLF configuration.
