Amphenol ICC 55508-332LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-332LF is a 32-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount board-to-board applications. This connector operates across -55°C to 125°C and is rated for 2A current at 200V. The part is active in production and RoHS compliant, making it suitable for general purpose, industrial, and medical applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 55508-332LF are qualified based on the following critical parameters that determine functional equivalence:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 32 positions at 0.079" (2.00mm) mating pitch
• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Operating Temperature Range: -55°C ~ 125°C
• Flammability Rating: UL94 V-0 compliance
• Electrical Performance: Current and voltage ratings sufficient for application requirements

The Samtec CLT-116-02-G-D and CLT-116-02-L-D meet these core substitution criteria. Both parts maintain identical mechanical and electrical interface specifications with the 55508-332LF, enabling direct board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both Samtec CLT-116 variants qualify as direct substitutes for the Amphenol ICC 55508-332LF based on matching mechanical interfaces, electrical specifications, and compliance certifications.

CLT-116-02-G-D: Features gold contact finish on both mating and post surfaces. This variant maintains full compliance with ROHS3 standards and provides enhanced corrosion resistance through dual-gold plating.

CLT-116-02-L-D: Features gold mating contact finish with tin post finish. This variant also maintains ROHS3 compliance and offers a cost-optimized alternative while preserving mating surface gold plating for signal integrity.

Both substitutes exceed the current rating of the primary part (4.1A per contact versus 2A), providing additional electrical margin. All three parts maintain identical mechanical footprints, pitch specifications, and push-pull fastening mechanisms, ensuring PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Are the Samtec CLT-116-02-G-D and CLT-116-02-L-D mechanically compatible with the Amphenol ICC 55508-332LF?

A: Yes. Both Samtec parts maintain identical mating pitch (0.079"), row spacing (0.079"), position count (32), and push-pull fastening type. PCB footprints are compatible without modification.

Q: What is the difference between CLT-116-02-G-D and CLT-116-02-L-D?

A: The primary difference is contact finish on the post termination. CLT-116-02-G-D uses gold plating on both mating and post surfaces, while CLT-116-02-L-D uses gold on mating surfaces and tin on post surfaces. Both maintain identical mating interface specifications.

Q: Do the substitute parts meet the same temperature and compliance requirements?

A: Yes. All three parts operate across -55°C to 125°C, maintain UL94 V-0 flammability rating, and are RoHS compliant (the Samtec parts are ROHS3 compliant, which supersedes RoHS compliance). Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: Are the electrical ratings of the substitute parts sufficient?

A: Yes. The Samtec CLT-116 variants are rated for 4.1A per contact, exceeding the 2A rating of the 55508-332LF. Both substitutes support the 200V application requirement of the primary part.

Q: What is the insulation material difference between the primary and substitute parts?

A: The 55508-332LF uses plastic insulation material, while the Samtec CLT-116 variants use Liquid Crystal Polymer (LCP). LCP provides enhanced mechanical and thermal properties while maintaining equivalent electrical performance and compliance certifications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application does not have specific material or finish requirements beyond the stated electrical and mechanical specifications. The identical pitch, position count, and fastening mechanism ensure direct substitution at the PCB level.
