Amphenol ICC 55508-338 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-338 is a 38-position receptacle connector in the Minitek® 2.00mm series, designed for board-to-board surface mount applications. This connector features 0.079" (2.00mm) pitch, gold-plated mating contacts, and push-pull fastening. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Active alternatives from both Amphenol ICC and Samtec Inc. provide functional equivalence with improved compliance status and availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following core parameters:

Connector type (Receptacle)
Number of positions (38)
Pitch and row spacing (0.079" / 2.00mm)
Mounting type (Surface Mount)
Fastening type (Push-Pull)
Contact finish material (Gold)
Operating temperature range (-55°C ~ 125°C)
Material flammability rating (UL94 V-0)
Moisture sensitivity level (1 / Unlimited)

Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Equivalent 55508-338LF is the active production equivalent from Amphenol ICC, differing only in RoHS compliance status (RoHS Compliant vs. non-compliant) and contact finish post material (Tin vs. Tin-Lead).

Category 2: Samtec CLT Series Alternatives CLT-119-02 variants from Samtec Inc. meet all core substitution parameters. These parts feature higher current rating per contact (4.1A vs. 2A) and use Liquid Crystal Polymer (LCP) insulation material instead of plastic. Variants differ in connector entry style (standard vs. bottom entry), packaging format (Bulk, Tube, Tape & Reel), and optional features (Board Guide, Pick and Place).

Engineering Selection Recommendations

For RoHS Compliance Requirements: Select 55508-338LF for direct Amphenol ICC equivalence with RoHS compliance. This part maintains identical electrical and mechanical specifications while meeting modern regulatory requirements. Alternatively, any Samtec CLT-119-02 variant provides ROHS3 compliance with enhanced current rating capability.

For Active Production Status: All substitute parts listed are in active production status, ensuring long-term availability and supply chain stability. The obsolete 55508-338 should be replaced with one of these active alternatives for new designs or ongoing production.

For Samtec CLT Series Selection: Choose CLT-119-02 variants based on connector entry style and packaging requirements. Standard entry variants (CLT-119-02-F-D and derivatives) are suitable for top-entry applications. Bottom entry variants (CLT-119-02-F-D-BE and derivatives) accommodate applications requiring connector access from the board underside. Packaging options include Bulk, Tube, and Tape & Reel formats for different manufacturing workflows.

For Enhanced Current Capacity: Samtec CLT-119-02 series provides 4.1A per contact versus 2A for the original part, offering improved current handling capability for higher-power applications while maintaining all other electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can 55508-338LF be used as a direct replacement for 55508-338? A: Yes. The 55508-338LF is the active production equivalent from Amphenol ICC. It maintains identical connector type, position count, pitch, mounting method, and fastening type. The primary differences are RoHS compliance status and contact finish post material (Tin vs. Tin-Lead), which do not affect functional compatibility in standard applications.

Q: What are the key differences between Amphenol ICC and Samtec CLT series substitutes? A: Both meet core substitution parameters (38 positions, 0.079" pitch, push-pull fastening, gold mating contacts, -55°C to 125°C operation). Samtec CLT variants feature higher current rating (4.1A per contact vs. 2A), Liquid Crystal Polymer insulation instead of plastic, and lower gold plating thickness on mating contacts (3.00µin vs. 15.0µin). Samtec parts are available in multiple entry styles and packaging formats.

Q: What is the difference between standard and bottom entry CLT variants? A: Standard entry CLT-119-02-F-D variants position the connector for top-side mating. Bottom entry CLT-119-02-F-D-BE variants allow connector access from the board underside, useful for space-constrained layouts or applications requiring connector placement on the board bottom.

Q: How do packaging options affect part selection? A: Packaging format does not affect electrical or mechanical compatibility. Bulk packaging suits low-volume or prototype applications. Tube packaging provides organized storage for manual assembly. Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly in high-volume production.

Q: Are there any mechanical dimension differences between the main part and substitutes? A: Insulation height differs slightly: 55508-338 and 55508-338LF measure 0.091" (2.30mm), while all Samtec CLT variants measure 0.083" (2.10mm). This 0.008" difference may affect board layout in space-constrained designs. Contact finish thickness on mating surfaces also differs (15.0µin vs. 3.00µin), though both meet gold plating specifications for the connector category.

Q: Which substitute part offers the best compliance profile? A: All Samtec CLT-119-02 variants carry ROHS3 compliance and REACH Unaffected status, representing the most current regulatory alignment. The 55508-338LF provides RoHS compliance with REACH Affected status. For new designs, Samtec CLT series is recommended for maximum compliance coverage.
