Amphenol ICC 55508-008 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-008 is an 8-position receptacle connector in the Minitek® 2.00mm series, designed for board-to-board surface mount applications. This part features a 0.079" (2.00mm) pitch, gold-plated mating contacts, and push-pull fastening. The 55508-008 is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Active alternatives from both Amphenol ICC and cross-manufacturer sources are available with compatible electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the 55508-008 is determined by strict equivalence in the following critical parameters: connector type (receptacle), number of positions (8), mating pitch (0.079" / 2.00mm), row configuration (2 rows with 0.079" spacing), mounting type (surface mount), termination method (solder), fastening type (push-pull), contact finish (gold), operating temperature range (-55°C ~ 125°C), and flammability rating (UL94 V-0).

The substitute parts are grouped into two categories:

Direct Amphenol ICC Equivalent: The 55508-008LF maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. The primary difference is the contact finish post material (tin instead of tin-lead) and packaging format (tube instead of unspecified).

Cross-Manufacturer Alternatives (Samtec CLT Series): The Samtec CLT-104 series receptacles meet all critical substitution parameters with enhanced current ratings (4.1A per contact versus 2A) and alternative insulation materials (liquid crystal polymer instead of plastic). These parts are available in multiple configurations: standard top-entry, bottom-entry, with or without board guides, and in both tube and tape-and-reel packaging. All CLT variants maintain the required 0.079" pitch, 8-position, 2-row configuration, push-pull fastening, and gold mating contact finish.

Engineering Selection Recommendations

For Direct Replacement (Active Amphenol ICC Part): The 55508-008LF is the primary substitute for the obsolete 55508-008. Both parts share identical mechanical dimensions, electrical ratings, and connector geometry. The 55508-008LF offers active product status, RoHS compliance, and improved supply chain availability. This part is suitable for designs requiring continuity with the original Minitek® 2.00mm platform.

For Enhanced Performance (Samtec CLT Series): The Samtec CLT-104 series provides higher current capacity (4.1A per contact versus 2A) and improved insulation material (liquid crystal polymer). These parts are suitable for applications requiring greater current handling or enhanced thermal stability. The CLT series is available in multiple configurations to accommodate different PCB layouts and assembly processes.

Packaging Considerations: Select tube packaging for lower-volume applications or manual assembly. Tape-and-reel packaging (TR designation) is specified for high-volume automated assembly processes. Board guide features (A designation) provide mechanical alignment during mating. Pick-and-place features (P designation) support automated component placement.

Compliance Requirements: All substitute parts meet UL94 V-0 flammability requirements and operate across the -55°C to 125°C temperature range. The 55508-008LF and all CLT variants are RoHS compliant, addressing regulatory requirements for new designs.

Frequently Asked Questions (FAQ)

Q: Can the 55508-008LF directly replace the obsolete 55508-008?

A: Yes. The 55508-008LF maintains identical connector type, position count, pitch, row configuration, mounting type, termination method, fastening type, contact finish, and operating temperature range. The primary differences are active product status, RoHS compliance, and contact post finish material (tin versus tin-lead).

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

A: The Amphenol ICC 55508-008LF maintains the original Minitek® 2.00mm series specifications. Samtec CLT-104 series parts offer higher current ratings (4.1A per contact), liquid crystal polymer insulation, and multiple configuration options including bottom-entry and board guide variants. All parts maintain the critical 0.079" pitch and 8-position, 2-row configuration.

Q: Are Samtec CLT-104 parts mechanically compatible with the original 55508-008?

A: Samtec CLT-104 receptacles are mechanically compatible for mating with standard 0.079" (2.00mm) pitch connectors. The insulation height differs slightly (0.083" versus 0.091"), but this does not affect mating compatibility. Verify PCB layout clearances for the specific CLT variant selected, particularly for bottom-entry configurations.

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

A: Tape-and-reel packaging (TR designation) is specified for automated assembly. Available CLT variants in tape-and-reel format include CLT-104-02-F-D-A-P-TR, CLT-104-02-F-D-A-TR, and CLT-104-02-F-D-BE-A-K-TR. Tube packaging is standard for lower-volume applications.

Q: Do all substitute parts meet the same compliance standards?

A: All substitute parts meet UL94 V-0 flammability requirements and operate across -55°C to 125°C. The 55508-008LF and all CLT variants are RoHS compliant. REACH compliance status varies by specific CLT variant; refer to individual part specifications for regulatory requirements.

Q: What is the difference between standard and bottom-entry CLT configurations?

A: Standard CLT-104-02-F-D variants feature top-entry mating. Bottom-entry variants (CLT-104-02-F-D-BE) are designed for applications where the mating connector approaches from the bottom of the PCB. Both configurations maintain identical electrical and mechanical specifications.

Q: Are board guide features necessary for my application?

A: Board guide features (A designation) provide mechanical alignment during mating and are recommended for applications requiring precise connector positioning or high-frequency signal integrity. Standard variants without board guides are suitable for general-purpose applications with less stringent alignment requirements.
