Amphenol ICC 55508-314 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-314 is a 14-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 a 2A current rating at 200V. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility, mechanical fit, and thermal performance within the specified operating range of -55°C to 125°C.

Substitute Part Grouping Explanation

Substitution for the 55508-314 is based on strict electrical and mechanical compatibility criteria. All substitute parts must maintain:

Identical connector type (receptacle), contact configuration (14-position, 2-row), and pitch (0.079" / 2.00mm)
Surface mount termination with solder connection
Female socket contact type with gold mating finish
Push-pull fastening mechanism
Operating temperature range of -55°C to 125°C
UL94 V-0 flammability rating
Equivalent or superior current and voltage ratings

The primary substitute is the Amphenol ICC 55508-314LF, which is the lead-free variant of the original part and maintains full electrical and mechanical compatibility. Secondary substitutes from Samtec Inc. (CLT series) provide enhanced performance characteristics while maintaining all critical compatibility parameters. Samtec CLT parts feature higher current ratings (4.1A per contact) and improved insulation material (Liquid Crystal Polymer), making them suitable for applications requiring greater thermal stability and contact reliability.

Engineering Selection Recommendations

The 55508-314LF is the direct replacement for the obsolete 55508-314. Both parts are manufactured by Amphenol ICC and maintain identical electrical and mechanical specifications. The primary distinction is that 55508-314LF is RoHS compliant with tin-lead post finish, whereas the original part is non-compliant. For new designs and production requiring regulatory compliance, 55508-314LF is the preferred choice.

Samtec CLT-107 series connectors provide enhanced performance alternatives with higher current ratings (4.1A per contact versus 2A) and superior insulation material (Liquid Crystal Polymer). These parts are ROHS3 compliant and maintain full mechanical and electrical compatibility with the original connector pitch and configuration. CLT series variants differ in packaging (tube or tape & reel), connector entry style (standard or bottom entry), and assembly features (board guide, pick and place capability).

For applications requiring standard tube packaging without additional features, CLT-107-02-F-D is the baseline substitute. For automated assembly processes, CLT-107-02-F-D-A-K-TR (with board guide, pick and place, and tape & reel packaging) provides optimized handling. For bottom entry applications, CLT-107-02-F-D-BE or CLT-107-02-F-D-BE-A accommodate space-constrained board layouts.

All substitute parts maintain the -55°C to 125°C operating temperature range and UL94 V-0 flammability rating required for industrial and medical applications.

Frequently Asked Questions (FAQ)

Q: Can CLT-107 series connectors directly replace the 55508-314 in existing designs?

A: Yes. All CLT-107 variants maintain the identical 14-position, 2-row configuration with 0.079" (2.00mm) pitch and push-pull fastening. Mechanical and electrical compatibility is preserved. The higher current rating (4.1A per contact) and LCP insulation material provide enhanced performance without requiring design modifications.

Q: What is the difference between standard and bottom entry CLT-107 connectors?

A: Standard CLT-107-02-F-D connectors feature top-entry mating. Bottom entry variants (CLT-107-02-F-D-BE and CLT-107-02-F-D-BE-A) accommodate applications where the mating connector approaches from below the board surface, enabling compact board layouts.

Q: Which packaging option should be selected for high-volume production?

A: Tape & reel (TR) packaging is recommended for automated pick-and-place assembly. CLT-107-02-F-D-A-K-TR combines tape & reel delivery with board guide and pick-and-place features for optimized manufacturing throughput. Tube packaging is suitable for manual assembly or lower-volume applications.

Q: Does the board guide feature affect mechanical compatibility?

A: No. The board guide (indicated by "-A" in the part number) is an optional assembly feature that improves alignment during mating but does not affect electrical or mechanical compatibility with standard connectors lacking this feature.

Q: Are all substitute parts RoHS compliant?

A: The 55508-314LF is RoHS compliant. All Samtec CLT-107 variants are ROHS3 compliant. The original 55508-314 is non-compliant and should not be used in new designs subject to RoHS regulations.

Q: What is the contact finish thickness difference between 55508-314 and CLT-107 series?

A: The 55508-314 specifies 15.0µin (0.38µm) gold mating contact finish. CLT-107 series specifies 3.00µin (0.076µm). Both finishes meet gold plating requirements for reliable mating contact performance. The CLT-107 specification reflects current industry standards for thin-film gold plating.
