Engineering Selection Recommendations

For Direct Replacement with Minimal Design Changes: The 55508-316LF is the recommended primary substitute. It maintains identical mechanical footprint and electrical specifications to the obsolete 55508-316 while achieving RoHS compliance through tin-lead post finish. This part is suitable for applications where existing PCB layouts and connector mating interfaces are fixed.

For New Designs and Enhanced Performance: The Samtec CLT-108-02 series provides superior electrical performance with 4.1A per contact rating versus the original 2A specification. All CLT variants maintain mechanical compatibility and push-pull fastening. Selection within the CLT family depends on application requirements:

CLT-108-02-F-D: Base configuration for standard entry applications with tube packaging
CLT-108-02-F-D-A / CLT-108-02-F-D-A-P: Include board guide feature for improved alignment; pick-and-place variant available
CLT-108-02-F-D-A-P-TR / CLT-108-02-F-D-A-TR: Tape & reel packaging for automated assembly processes
CLT-108-02-F-D-BE / CLT-108-02-F-D-BE-A / CLT-108-02-F-D-BE-A-K / CLT-108-02-F-D-BE-A-K-TR: Bottom entry variants for applications requiring cable entry from the board underside; pick-and-place and tape & reel options available

All Samtec CLT variants achieve ROHS3 compliance and feature liquid crystal polymer insulation for enhanced thermal and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 55508-316LF be used as a direct drop-in replacement for the obsolete 55508-316? A: Yes. The 55508-316LF maintains identical connector geometry, pitch, row spacing, mounting type, and electrical ratings. The primary difference is the post finish material (tin-lead vs. tin-lead in the original), which does not affect mechanical compatibility or mating interface performance.

Q: What is the primary advantage of Samtec CLT-108-02 connectors over the Amphenol ICC alternatives? A: The CLT-108-02 series provides doubled current capacity (4.1A per contact vs. 2A) while maintaining identical pitch and mechanical configuration. Additionally, CLT variants use liquid crystal polymer insulation, which offers superior thermal stability and dimensional consistency compared to standard plastic insulation.

Q: Are all CLT-108-02 variants mechanically interchangeable? A: CLT-108-02 variants with standard entry (CLT-108-02-F-D through CLT-108-02-F-D-A-TR) are mechanically interchangeable with the original 55508-316. Bottom entry variants (CLT-108-02-F-D-BE series) require different PCB footprints due to connector orientation and are not interchangeable with standard entry designs.

Q: What packaging options are available, and how do they affect component selection? A: Tube packaging is suitable for manual assembly and low-volume applications. Tape & reel (TR) and cut tape (CT) packaging are designed for automated pick-and-place assembly. The CLT-108-02-F-D-A-P-TR variant combines tape & reel packaging with pick-and-place features for high-volume manufacturing.

Q: Do all substitute parts meet the same compliance standards as the original 55508-316? A: The 55508-316 is RoHS non-compliant. The 55508-316LF achieves RoHS compliance. All Samtec CLT-108-02 variants achieve ROHS3 compliance, which represents the current regulatory standard. For applications requiring REACH compliance, the 55508-316LF and CLT-108-02-F-D-BE-A are REACH Affected; other CLT variants are REACH Unaffected.

Q: What is the difference between standard entry and bottom entry connector variants? A: Standard entry connectors (CLT-108-02-F-D series) accept mating plugs from the top of the board. Bottom entry variants (CLT-108-02-F-D-BE series) are designed for cable entry from the board underside, requiring different PCB layout and footprint design.

Q: Are board guide and pick-and-place features required for my application? A: Board guide features improve connector alignment during mating and are optional. Pick-and-place features facilitate automated assembly but are not necessary for manual assembly processes. Selection depends on manufacturing process requirements and assembly volume.
