Engineering Selection Recommendations

For RoHS-compliant applications: The 55508-304LF provides direct Amphenol ICC equivalence with active product status and RoHS compliance, making it the preferred choice for new designs and regulated industries.

For Samtec CLT series selection: All CLT-102-02 variants meet the core electrical and mechanical requirements. Selection between standard and bottom entry configurations depends on PCB layout requirements. The CLT-102-02-F-D and CLT-102-02-FM-D variants offer standard top-entry mounting, while CLT-102-02-F-D-BE and CLT-102-02-FM-D-BE provide bottom entry capability for space-constrained designs.

For packaging considerations: Tape & Reel (TR) packaged variants (CLT-102-02-F-D-TR, CLT-102-02-FM-D-TR, CLT-102-02-F-D-BE-TR, CLT-102-02-FM-D-BE-TR) are suitable for automated assembly processes. Bulk and standard packaging options are available for manual assembly or lower-volume applications.

For contact finish requirements: CLT-102-02-G-D features dual gold finish on both mating and post contacts, providing enhanced corrosion resistance compared to tin-finished alternatives.

For current capacity: Samtec CLT series parts support 4.1A per contact, exceeding the 2A rating of the original 55508-304, providing design margin for higher-current applications.

Frequently Asked Questions (FAQ)

Q: Can CLT-102-02 series connectors directly replace the 55508-304 in existing designs? A: Yes. All CLT-102-02 variants maintain identical mating pitch (0.079" / 2.00mm), row configuration, connector type (receptacle), and fastening mechanism (push-pull). Mechanical and electrical compatibility is confirmed. Minor differences in insulation height (0.083" vs. 0.091") and insulation material (LCP vs. plastic) do not affect functional compatibility in standard board-to-board applications.

Q: What is the difference between standard and bottom entry CLT variants? A: Standard variants (CLT-102-02-F-D, CLT-102-02-FM-D) feature top-entry mating. Bottom entry variants (CLT-102-02-F-D-BE, CLT-102-02-FM-D-BE) allow mating from the bottom side of the PCB, enabling compact designs where top-side access is limited.

Q: Why do CLT-102-02 parts have higher current ratings (4.1A per contact) than the original 55508-304 (2A)? A: The CLT series uses Liquid Crystal Polymer (LCP) insulation material and optimized contact geometry, providing improved thermal performance and current-carrying capacity. This represents a design enhancement and does not affect backward compatibility.

Q: What packaging options are available for automated assembly? A: Tape & Reel (TR) packaging is available for all CLT-102-02 variants, suitable for pick-and-place assembly. Bulk packaging is available for manual assembly or lower-volume production runs.

Q: Is the 55508-304LF a direct replacement for the obsolete 55508-304? A: Yes. The 55508-304LF is the active equivalent from Amphenol ICC, maintaining identical electrical and mechanical specifications while adding RoHS compliance and improved post contact finish (tin vs. tin-lead).

Q: What is the difference between CLT-102-02-F-D and CLT-102-02-FM-D? A: Both variants maintain identical electrical and mechanical specifications. The designation difference reflects internal design variations within the CLT series. Both are functionally equivalent for the 55508-304 replacement application.

Q: Does CLT-102-02-G-D offer advantages over other CLT variants? A: CLT-102-02-G-D features gold plating on both mating and post contacts (10.0µin mating, 3.00µin post), compared to tin post finish on other CLT variants. This provides enhanced corrosion resistance for applications requiring extended shelf life or harsh environmental exposure.
