Equivalent & Substitute Parts for 55508-310LF

Part Overview

The Amphenol ICC 55508-310LF is a 10-position receptacle connector in the Minitek® 2.00mm series, designed for board-to-board surface mount applications. This connector features a 0.079" (2.00mm) pitch, gold-plated mating contacts, and operates across -55°C to 125°C. The part is active and RoHS compliant, serving general purpose, industrial, and medical applications with a 2A current rating at 200V.

Equivalent and substitute parts are identified based on matching electrical and mechanical specifications: connector type, contact configuration, pitch, mounting method, operating temperature range, and material compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 55508-310LF are qualified based on the following critical parameters:

• Connector Configuration: 10-position receptacle, 2-row layout, 0.079" (2.00mm) pitch and row spacing
• Mounting and Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Operating Environment: -55°C to 125°C temperature range
• Material Compliance: UL94 V-0 flammability rating and RoHS compliance
• Contact Material: Phosphor bronze construction
• Contact Type: Female socket contacts

The three substitute parts listed below meet these core electrical and mechanical requirements. Variations in packaging format (tube, cut tape, tape & reel), insulation material (plastic vs. liquid crystal polymer), contact finish thickness, and current rating per contact do not preclude functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status and full compliance certifications. Selection among CLT-105-02-G-D, CLT-105-02-L-D-A-TR, and CLT-105-02-L-D-K-TR should be based on packaging and supply requirements:

CLT-105-02-G-D is supplied in tube packaging with 782 pieces in stock. This option is suitable for lower-volume applications or manual assembly processes.

CLT-105-02-L-D-A-TR is supplied in cut tape format with 1615 pieces in stock and includes a board guide feature. This packaging supports semi-automated assembly workflows.

CLT-105-02-L-D-K-TR is supplied in tape & reel format with 12300 pieces in stock and includes pick-and-place compatibility. This option is optimized for high-volume automated manufacturing.

All three substitute parts maintain ROHS3 compliance, which exceeds the RoHS compliance of the original part. The Samtec CLT series connectors are rated for 4.1A per contact, providing higher current capacity than the 2A rating of the 55508-310LF.

Frequently Asked Questions (FAQ)

Q: Can CLT-105-02-G-D, CLT-105-02-L-D-A-TR, and CLT-105-02-L-D-K-TR be used interchangeably with 55508-310LF?

A: Yes. All three substitute parts share identical electrical and mechanical specifications for connector type, position count, pitch, row spacing, mounting method, contact configuration, fastening type, operating temperature range, and material compliance. Differences in packaging format do not affect functional compatibility.

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

A: The three parts are electrically and mechanically identical. They differ in packaging format: CLT-105-02-G-D uses tube packaging, CLT-105-02-L-D-A-TR uses cut tape with board guide, and CLT-105-02-L-D-K-TR uses tape & reel with pick-and-place capability. Selection depends on assembly process requirements and volume.

Q: Are there differences in insulation material between the main part and substitutes?

A: Yes. The 55508-310LF uses plastic insulation, while all three Samtec substitutes use liquid crystal polymer (LCP) insulation. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range.

Q: What is the current rating difference?

A: The 55508-310LF is rated for 2A total current. The Samtec CLT series substitutes are rated for 4.1A per contact, providing higher current capacity. This does not prevent substitution; the higher rating ensures adequate performance in existing applications.

Q: Do all parts meet RoHS requirements?

A: Yes. The 55508-310LF is RoHS compliant. All three Samtec substitutes are ROHS3 compliant, which represents an updated compliance standard and is fully compatible with RoHS requirements.

Q: What is the moisture sensitivity level for all parts?

A: All parts, including the main part and all three substitutes, have a moisture sensitivity level of 1 (unlimited), indicating no special moisture handling requirements during storage or assembly.
