Amphenol ICC 55508-136 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-136 is a 36-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount board-to-board applications. This part operates across the -55°C to 125°C temperature range with a 2A current rating and 200V voltage rating. The 55508-136 is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Active alternatives are available from both Amphenol ICC and Samtec Inc. that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (36), mating pitch (0.079"/2.00mm), row configuration (2 rows at 0.079" spacing), mounting type (surface mount), termination method (solder), fastening type (push-pull), operating temperature range (-55°C to 125°C), material flammability rating (UL94 V-0), contact material (phosphor bronze), and contact shape (square).

The substitute parts are grouped into two categories:

Category 1: Amphenol ICC Direct Substitutes – Parts that maintain the Minitek® 2.00mm series designation and plastic insulation material. The 55508-136LF represents the active production equivalent with RoHS compliance and tin-lead post finish upgrade.

Category 2: Samtec Inc. CLT Series Alternatives – Parts that meet all electrical and mechanical parameters while utilizing liquid crystal polymer (LCP) insulation material and offering enhanced current ratings (4.1A per contact). These parts are available in multiple configurations with board guide and pick-and-place features, and packaging options including tape and reel.

Frequently Asked Questions (FAQ)

Q: Can the 55508-136LF be used as a direct replacement for the 55508-136?

A: Yes. The 55508-136LF maintains identical electrical and mechanical specifications including connector type, position count, pitch, row spacing, mounting type, termination, fastening type, operating temperature, and flammability rating. The primary differences are product status (active versus obsolete) and RoHS compliance.

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

A: Amphenol ICC 55508-136LF maintains the plastic insulation material and 2A current rating of the original part. Samtec CLT-118 series parts use liquid crystal polymer insulation and provide 4.1A per contact current rating. All parts meet the same electrical and mechanical interface requirements for 36-position, 0.079" pitch, surface mount, push-pull receptacle connectors.

Q: Are Samtec CLT-118 parts compatible with existing PCB designs for the 55508-136?

A: Yes. The CLT-118 series maintains identical mating pitch (0.079"/2.00mm), row spacing (0.079"/2.00mm), number of positions (36), and mounting type (surface mount). PCB footprints designed for the 55508-136 are compatible with CLT-118 receptacles.

Q: What packaging options are available for high-volume production?

A: Amphenol ICC 55508-136LF is available in tube packaging. Samtec CLT-118 series offers multiple packaging options: standard tube (CLT-118-02-F-D-A, CLT-118-02-F-D-A-P, CLT-118-02-F-D-BE, CLT-118-02-F-D-BE-A) and tape and reel (CLT-118-02-F-D-A-K-TR, CLT-118-02-F-D-A-P-TR). Tape and reel packaging supports automated pick-and-place assembly.

Q: Do all substitute parts meet the same temperature and compliance requirements?

A: Yes. All substitute parts operate across -55°C to 125°C, maintain UL94 V-0 flammability rating, and have moisture sensitivity level 1 (unlimited). Amphenol ICC 55508-136LF is RoHS compliant. All Samtec CLT-118 variants are ROHS3 compliant.

Q: What is the difference between standard CLT-118-02-F-D-A and bottom-entry CLT-118-02-F-D-BE variants?

A: Both maintain identical electrical and mechanical specifications. The bottom-entry variant (CLT-118-02-F-D-BE) accommodates mating connectors inserted from the bottom of the PCB, while the standard variant accommodates top-entry insertion. Selection depends on PCB layout and assembly requirements.
