Substitute Categories:

Category 1: Direct Amphenol ICC Equivalent The 55508-326LF is the direct successor from Amphenol ICC, maintaining identical mechanical and electrical specifications while offering RoHS compliance and active product status.

Category 2: Samtec CLT Series Alternatives Samtec CLT-113 series connectors provide functional equivalence with enhanced current rating (4.1A per contact vs. 2A) and improved contact finish thickness (3.00µin). These parts are available in multiple configurations: standard board guide (CLT-113-02-F-D-A), bottom entry (CLT-113-02-F-D-BE-A), and automated assembly variants with pick-and-place features (CLT-113-02-F-D-A-K-TR, CLT-113-02-F-D-A-P-TR). All Samtec variants use Liquid Crystal Polymer (LCP) insulation instead of plastic and carry ROHS3 compliance.

Engineering Selection Recommendations

For Direct Replacement (Amphenol ICC Ecosystem): The 55508-326LF is the recommended direct substitute. It maintains identical mechanical and electrical specifications while transitioning to active product status and RoHS compliance. This option is optimal for designs already qualified to Amphenol ICC Minitek® 2.00mm connectors.

For Enhanced Performance (Samtec CLT Series): Samtec CLT-113 series connectors provide superior current handling (4.1A per contact vs. 2A) and are available in multiple configurations. Select based on application requirements:

CLT-113-02-F-D-A: Standard configuration with board guide for general applications
CLT-113-02-F-D-BE-A: Bottom entry variant for space-constrained PCB layouts
CLT-113-02-F-D-A-K-TR: Tape & reel with pick-and-place features for high-volume automated assembly
CLT-113-02-F-D-A-P-TR: Tape & reel with board guide and pick-and-place for precision placement

All Samtec variants carry ROHS3 compliance and feature Liquid Crystal Polymer (LCP) insulation, providing improved dimensional stability and environmental resistance compared to plastic insulation.

Compliance Considerations: The 55508-326 is RoHS non-compliant. All substitute options (55508-326LF and all Samtec CLT variants) meet current RoHS requirements, making them suitable for applications subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can I use Samtec CLT-113 connectors as a direct replacement for the Amphenol ICC 55508-326?

A: Yes. Both connector families maintain identical 26-position, 0.079" (2.00mm) pitch, 2-row board-to-board surface mount configurations with push-pull fastening and gold-plated mating contacts. Mechanical and electrical interfaces are compatible. The Samtec CLT series offers enhanced current rating (4.1A per contact) and improved insulation material (LCP), making it functionally superior while maintaining full mechanical compatibility.

Q: What is the difference between CLT-113-02-F-D-A and CLT-113-02-F-D-BE-A?

A: The primary difference is connector orientation. CLT-113-02-F-D-A is a standard top-entry receptacle, while CLT-113-02-F-D-BE-A is a bottom-entry variant. Bottom-entry connectors are used in applications where PCB space is limited or where cable routing requires entry from the board underside. Both maintain identical electrical specifications and 26-position, 2.00mm pitch configuration.

Q: Why do some Samtec CLT variants include "-K-TR" or "-P-TR" suffixes?

A: These suffixes indicate packaging and assembly features. "-TR" denotes Tape & Reel packaging for automated pick-and-place assembly. "-K" indicates pick-and-place compatible features. "-P" indicates board guide with pick-and-place compatibility. These variants are optimized for high-volume surface mount assembly processes.

Q: Is the 55508-326LF identical to the 55508-326?

A: The 55508-326LF maintains identical mechanical and electrical specifications, including 26 positions, 0.079" (2.00mm) pitch, gold-plated contacts, and 2A current rating. The primary differences are product status (active vs. obsolete), RoHS compliance (compliant vs. non-compliant), and contact finish post material (tin vs. tin-lead). The "LF" designation indicates lead-free compliance.

Q: What is the current rating difference between the 55508-326 and Samtec CLT-113 series?

A: The 55508-326 is rated at 2A total current, while Samtec CLT-113 connectors are rated at 4.1A per contact. This higher rating in the Samtec series provides additional design margin for applications requiring higher current density or future performance upgrades.

Q: Are all substitute parts compatible with existing PCB layouts designed for the 55508-326?

A: Yes, all listed substitutes maintain identical 26-position, 0.079" (2.00mm) pitch, and 2-row spacing. Standard top-entry variants (55508-326LF, CLT-113-02-F-D, CLT-113-02-F-D-A) are direct mechanical replacements. Bottom-entry variants (CLT-113-02-F-D-BE-A) require PCB footprint modification to accommodate bottom-entry orientation.

Q: Which substitute is best for high-volume automated assembly?

A: CLT-113-02-F-D-A-K-TR or CLT-113-02-F-D-A-P-TR are optimized for automated assembly. Both are supplied in Tape & Reel packaging with pick-and-place compatible features, reducing manual handling and improving placement accuracy in high-speed surface mount assembly lines.
