Amphenol ICC 55508-010 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-010 is a 10-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount board-to-board applications. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 125°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility while meeting current compliance requirements.

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 (10), mating pitch (0.079"/2.00mm), number of rows (2), mounting type (surface mount), fastening type (push-pull), contact finish (gold), and termination method (solder). Parts meeting all these criteria are classified as direct substitutes. Variations in contact finish thickness, insulation material, current rating per contact, or operating temperature ceiling do not disqualify substitution when the core electrical and mechanical interfaces remain identical.

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC 55508-010LF

The 55508-010LF is the direct successor to the obsolete 55508-010, maintaining identical electrical and mechanical specifications while achieving RoHS compliance. This part is the preferred replacement when design constraints permit, as it preserves all original interface characteristics and operating parameters.

Secondary Substitutes: Samtec CLT Series

The Samtec CLT-105-02 series (CLT-105-02-F-D, CLT-105-02-F-D-A, CLT-105-02-F-D-A-P, CLT-105-02-F-D-A-P-TR, CLT-105-02-F-D-A-TR, CLT-105-02-F-D-BE, CLT-105-02-F-D-BE-A) provides functionally equivalent receptacle connectors with identical mating pitch, position count, and operating temperature range. These parts offer enhanced current capacity (4.1A per contact versus 2A) and RoHS3 compliance. Variants with board guide features (-A suffix) and pick-and-place accommodation (-P suffix) are available. Tape & Reel packaging (-TR suffix) is specified for automated assembly environments.

Tertiary Substitutes: Molex Milli-Grid Series

The Molex 0872631023 and 0873401024 maintain core connector geometry and surface mount compatibility but operate at reduced maximum temperature (-55°C to 105°C) and lower current/voltage ratings (1A, 125VAC). These parts are suitable only when application requirements do not exceed these electrical limits.

Frequently Asked Questions (FAQ)

Q: Can the 55508-010LF directly replace the obsolete 55508-010?

A: Yes. The 55508-010LF is electrically and mechanically equivalent to the 55508-010, with identical pin count, pitch, operating temperature range, and current/voltage ratings. The primary difference is RoHS compliance status. No design modifications are required.

Q: What is the difference between Samtec CLT variants with and without the -A suffix?

A: The -A suffix indicates the presence of a board guide feature, which provides mechanical alignment assistance during assembly. Both versions maintain identical electrical specifications and mating interfaces. Selection depends on assembly process requirements.

Q: Are Samtec CLT parts compatible with the original 55508-010 footprint?

A: Yes. All CLT-105-02 variants share the same 0.079" (2.00mm) mating pitch, 10-position configuration, and surface mount termination as the 55508-010. Mechanical compatibility is maintained across all listed CLT variants.

Q: What does the -TR suffix indicate on Samtec part numbers?

A: The -TR suffix specifies Tape & Reel packaging, which is standard for high-volume automated assembly. Tube packaging is used for lower-volume or manual assembly applications. Both packaging formats contain identical connector components.

Q: Why do Molex parts show lower current and voltage ratings?

A: The Molex 0872631023 and 0873401024 are designed for different application profiles with reduced electrical requirements. These parts are substitutes only when application specifications do not exceed 1A current or 125VAC voltage limits.

Q: Is the operating temperature difference between 125°C and 105°C significant for substitution?

A: The 55508-010 and Samtec CLT series operate to 125°C, while Molex parts are rated to 105°C. For applications requiring operation above 105°C, Molex substitutes are not suitable. Samtec and Amphenol ICC alternatives maintain the full temperature range.
