Engineering Selection Recommendations
All Samtec CLT-120 series substitutes listed are active products with ROHS3 compliance, addressing the obsolescence of the Amphenol ICC 55508-040. Selection among CLT variants depends on application-specific requirements:
Standard Configuration (Top Entry): CLT-120-02-F-D, CLT-120-02-F-D-A, CLT-120-02-F-D-A-P, and CLT-120-02-F-D-A-P-TR provide standard receptacle mounting with optional board guide and pick-and-place features.
Bottom Entry Configuration: CLT-120-02-F-D-BE, CLT-120-02-F-D-BE-A, CLT-120-02-F-D-BE-A-K, CLT-120-02-F-D-BE-A-K-TR, and CLT-120-02-F-D-BE-A-P accommodate bottom-entry mating requirements with board guide and pick-and-place options.
Packaging Considerations: Tube packaging is standard for most variants. Tape & Reel (TR) packaging is available for CLT-120-02-F-D-A-P-TR and CLT-120-02-F-D-BE-A-K-TR for automated assembly processes.
Feature Selection: Board Guide feature is available across all variants. Pick and Place feature is included in CLT-120-02-F-D-A-P, CLT-120-02-F-D-A-P-TR, CLT-120-02-F-D-BE-A-K, CLT-120-02-F-D-BE-A-K-TR, and CLT-120-02-F-D-BE-A-P variants.
Frequently Asked Questions (FAQ)
Q: Can CLT-120 series connectors directly replace the Amphenol ICC 55508-040?
A: Yes. All CLT-120 variants listed maintain identical electrical and mechanical specifications for the critical parameters: 40 positions, 0.079" (2.00mm) pitch, 2-row configuration, surface mount solder termination, push-pull fastening, gold-plated mating contacts, and -55°C to 125°C operating range. The CLT series provides enhanced current rating (4.1A per contact versus 2A) and ROHS3 compliance.
Q: What is the difference between standard and bottom-entry CLT-120 connectors?
A: Standard CLT-120 receptacles (CLT-120-02-F-D series) feature top-entry mating. Bottom-entry variants (CLT-120-02-F-D-BE series) accommodate mating from the bottom of the PCB. Selection depends on board layout and connector accessibility requirements.
Q: Does packaging type affect electrical or mechanical compatibility?
A: No. Tube and Tape & Reel packaging are supply format options only. Electrical and mechanical specifications remain identical. Tape & Reel packaging is specified for high-volume automated assembly processes.
Q: What is the Board Guide feature?
A: Board Guide is a mechanical feature that aids in connector alignment during mating. It is available as an option across CLT-120 variants and does not affect electrical performance or pin compatibility.
Q: What is the Pick and Place feature?
A: Pick and Place refers to surface mount assembly compatibility features that facilitate automated component placement during manufacturing. This feature is available on select CLT-120 variants and does not affect electrical or mechanical mating characteristics.
Q: Are there current rating differences between the main part and substitutes?
A: Yes. The Amphenol ICC 55508-040 is rated at 2A, while CLT-120 series connectors are rated at 4.1A per contact. This higher rating in the substitute parts provides additional design margin and does not create compatibility issues.
Q: What is the significance of ROHS3 compliance on the CLT-120 series?
A: ROHS3 compliance indicates conformance to Restriction of Hazardous Substances regulations. The Amphenol ICC 55508-040 is RoHS non-compliant, while all CLT-120 substitutes are ROHS3 compliant, making them suitable for applications with regulatory compliance requirements.
Q: Does insulation material change affect connector performance?
A: The CLT-120 series uses Liquid Crystal Polymer (LCP) insulation instead of plastic. LCP provides superior thermal and mechanical properties while maintaining electrical performance and UL94 V-0 flammability rating. This substitution is functionally equivalent for the specified application parameters.
