Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 55508-322LF are qualified based on the following critical parameters that determine functional equivalence:

• 22-position receptacle configuration with dual-row layout
• 0.079" (2.00mm) mating pitch and row spacing
• Surface mount solder termination
• Push-pull fastening mechanism
• Operating temperature range of -55°C to 125°C
• UL94 V-0 flammability compliance
• Phosphor bronze contact material
• Gold-plated mating contact finish

The Samtec CLT-111-02-G-D and CLT-111-02-L-D connectors meet these core substitution criteria. Both parts maintain identical mechanical interfaces, electrical operating ranges, and board-to-board connectivity standards. Variations in contact finish thickness and post-side plating do not affect functional substitutability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both Samtec CLT-111 series connectors (CLT-111-02-G-D and CLT-111-02-L-D) are qualified substitutes for the Amphenol ICC 55508-322LF based on active product status and regulatory compliance. All three parts maintain UL94 V-0 flammability certification, RoHS compliance (with Samtec parts meeting ROHS3 standard), and unlimited moisture sensitivity level rating.

The CLT-111-02-G-D features gold post-side plating, while the CLT-111-02-L-D uses tin post-side plating. Selection between these variants depends on soldering process requirements and post-side contact finish specifications for your application. Both maintain identical mating interface characteristics and operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can CLT-111-02-G-D and CLT-111-02-L-D be used interchangeably with the 55508-322LF?

A: Yes. Both Samtec parts maintain the same 22-position, 0.079" (2.00mm) pitch receptacle configuration, surface mount termination, and push-pull fastening. The mating interface is functionally equivalent. Selection between CLT-111-02-G-D and CLT-111-02-L-D depends on post-side plating requirements for your assembly process.

Q: What is the difference between CLT-111-02-G-D and CLT-111-02-L-D?

A: The primary difference is post-side contact finish. CLT-111-02-G-D uses gold plating on the post side, while CLT-111-02-L-D uses tin plating. Both maintain identical mating contact specifications and electrical performance.

Q: Are there dimensional differences between the 55508-322LF and Samtec CLT-111 series?

A: Insulation height differs slightly: the 55508-322LF measures 0.091" (2.30mm) while CLT-111 series measures 0.083" (2.10mm). This 0.008" (0.20mm) difference should be evaluated for your specific PCB layout and mating connector clearance requirements.

Q: Do all three connectors support the same current rating?

A: The 55508-322LF is rated for 2A total current, while CLT-111-02-G-D and CLT-111-02-L-D are rated for 4.1A per contact. The Samtec parts provide higher current capacity and are suitable for applications requiring the 55508-322LF's 2A specification.

Q: Are there compliance differences between these parts?

A: All three parts are active products with UL94 V-0 flammability compliance and unlimited MSL rating. Samtec parts carry ROHS3 compliance while the Amphenol part carries RoHS compliance. Both standards meet current regulatory requirements.

Q: What is the contact finish thickness difference?

A: The 55508-322LF has 15.0µin (0.38µm) mating contact gold plating, while CLT-111 series has 10.0µin (0.25µm). Both thicknesses are within standard specifications for 0.079" (2.00mm) pitch connectors and do not affect functional substitutability.
