Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 55508-324LF are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type & Contact Configuration: Receptacle with 24 female socket positions
• Pitch & Row Spacing: 0.079" (2.00mm) mating pitch with 2-row dual configuration
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Material & Finish: Phosphor bronze with gold mating surface
• Operating Environment: -55°C to 125°C temperature range, UL94 V-0 flammability rating
• Electrical Performance: Minimum 2A current rating and 200V voltage capability

The substitute parts CLT-112-02-G-D and CLT-112-02-L-D from Samtec Inc. meet these core substitution criteria. Both parts maintain identical mechanical interfaces, electrical contact configuration, and environmental ratings required for direct replacement in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both Samtec CLT-112-02-G-D and CLT-112-02-L-D connectors are qualified substitutes for the Amphenol ICC 55508-324LF based on product status and compliance certifications. All three parts maintain active production status and meet UL94 V-0 flammability requirements with unlimited moisture sensitivity ratings.

The Samtec alternatives provide enhanced current-carrying capacity at 4.1A per contact compared to the 2A rating of the primary part, supporting higher-power applications within the same mechanical envelope. Both substitute parts are ROHS3 compliant and carry EAR99 export classification matching the original component.

The primary distinction between the two Samtec options is the contact finish on the post termination: CLT-112-02-G-D features gold plating while CLT-112-02-L-D uses tin plating. Selection between these variants depends on soldering process requirements and post-plating specifications for your application.

Frequently Asked Questions (FAQ)

Q: Can CLT-112-02-G-D and CLT-112-02-L-D be used interchangeably with the 55508-324LF?

A: Yes, both Samtec parts are mechanically and electrically compatible substitutes. They maintain identical mating pitch (0.079"), row spacing (0.079"), position count (24), and push-pull fastening configuration. All three parts are surface mount receptacles with solder termination and operate across the same temperature range (-55°C to 125°C).

Q: What is the difference between CLT-112-02-G-D and CLT-112-02-L-D?

A: The primary difference is the contact finish on the post termination. CLT-112-02-G-D uses gold plating (3.00µin / 0.076µm thickness) while CLT-112-02-L-D uses tin plating. Both maintain identical gold mating contact finish (10.0µin / 0.25µm). Selection depends on your PCB soldering process and post-plating specifications.

Q: Are there dimensional differences between the original part and substitutes?

A: The insulation height differs slightly. The 55508-324LF has an insulation height of 0.091" (2.30mm) while both Samtec substitutes measure 0.083" (2.10mm). This 0.008" (0.20mm) difference should be evaluated for your specific board layout and mating connector clearance requirements.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are UL94 V-0 rated, carry MSL 1 (Unlimited) moisture sensitivity, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The Samtec parts are ROHS3 compliant while the original is RoHS compliant, both meeting regulatory requirements.

Q: What is the current rating difference?

A: The 55508-324LF is rated at 2A, while both Samtec substitutes are rated at 4.1A per contact. This higher rating in the substitute parts provides additional design margin for power delivery applications without changing the mechanical or electrical interface.

Q: Are inventory levels a consideration for part selection?

A: Current inventory shows 748 units of the 55508-324LF, 961 units of CLT-112-02-G-D, and 1028 units of CLT-112-02-L-D. All parts are available in production quantities for immediate procurement.
