Amphenol ICC 55508-010LF Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-010LF 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 active in production with 1151 units in current inventory. Substitute parts are necessary to address packaging requirements, inventory availability, or specific application constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 10
• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• Contact Material: Phosphor Bronze
• Style: Board to Board

All three substitute parts from Samtec Inc. (CLT series) meet these core electrical and mechanical requirements. Variations in packaging format (Tube, Cut Tape, Tape & Reel), contact finish specifications, insulation material composition, and current rating do not affect core substitutability for standard board-to-board interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

All three Samtec CLT-105 variants are electrically and mechanically equivalent to the Amphenol ICC 55508-010LF for board-to-board interconnect applications. Selection among substitutes is determined by packaging and supply requirements:

CLT-105-02-G-D (Tube packaging) provides direct packaging equivalence to the original part and is suitable for manual assembly or low-volume production runs.

CLT-105-02-L-D-A-TR (Cut Tape packaging) accommodates semi-automated pick-and-place operations with board guide features and represents the highest current inventory level (1615 units).

CLT-105-02-L-D-K-TR (Tape & Reel packaging) is optimized for high-volume automated assembly and offers the largest available inventory (12300 units). This variant includes pick-and-place features.

All substitute parts maintain active product status, UL94 V-0 flammability compliance, and RoHS3 certification. The Samtec parts feature higher current ratings (4.1A per contact versus 2A) and Liquid Crystal Polymer insulation material, which do not restrict substitutability.

Frequently Asked Questions (FAQ)

Q: Can CLT-105-02-L-D-K-TR be used as a direct replacement for 55508-010LF in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications for connector type, position count, pitch, row configuration, mounting method, and operating temperature range. The Tape & Reel packaging format does not affect electrical performance; it is a supply chain consideration.

Q: What is the difference between the three Samtec substitute options?

A: The three CLT-105 variants differ only in packaging format and inventory availability. CLT-105-02-G-D ships in Tube format (782 units available). CLT-105-02-L-D-A-TR ships in Cut Tape with board guide features (1615 units available). CLT-105-02-L-D-K-TR ships in Tape & Reel with pick-and-place features (12300 units available). All three are electrically identical.

Q: Does the higher current rating of Samtec parts (4.1A per contact) affect compatibility?

A: No. Higher current rating indicates greater capability and does not restrict substitutability. The original part specification of 2A per contact is fully supported by all substitute parts.

Q: Are there any insulation material differences that affect performance?

A: The original part uses plastic insulation; substitute parts use Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range (-55°C to 125°C). Material selection does not affect electrical or mechanical compatibility.

Q: Which substitute part should be selected for high-volume production?

A: CLT-105-02-L-D-K-TR (Tape & Reel format) is recommended for high-volume automated assembly due to its pick-and-place optimization and largest inventory availability (12300 units).

Q: Are all parts RoHS compliant?

A: Yes. The original part is RoHS Compliant. All three substitute parts are ROHS3 Compliant, which represents an updated compliance standard and does not restrict substitutability.
