Engineering Selection Recommendations

For direct replacement of the obsolete 55508-016 in existing designs, the Amphenol ICC 55508-016LF is the primary choice. It maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance, eliminating regulatory and supply chain risk.

For new designs or applications requiring enhanced current capacity, Samtec CLT-108-02-F-D series connectors provide functional equivalence with 4.1A per contact rating. The base CLT-108-02-F-D variant is suitable for standard applications. CLT-108-02-F-D-A adds board guide features for improved mechanical stability. CLT-108-02-F-D-A-P includes pick-and-place features for automated assembly. CLT-108-02-F-D-A-P-TR and CLT-108-02-F-D-A-TR are supplied in tape-and-reel packaging for high-volume production.

For applications requiring bottom entry connector orientation, CLT-108-02-F-D-BE and its variants (CLT-108-02-F-D-BE-A, CLT-108-02-F-D-BE-A-K, CLT-108-02-F-D-BE-A-K-TR) provide the same electrical performance with alternative mounting geometry. All Samtec CLT variants carry ROHS3 compliance and UL94 V-0 flammability certification.

Frequently Asked Questions (FAQ)

Q: Can the 55508-016LF be used as a direct drop-in replacement for the 55508-016?

A: Yes. The 55508-016LF maintains identical pitch (0.079"), position count (16), row configuration (2 rows), mounting type (surface mount), and operating temperature range (-55°C to 125°C). The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What are the key differences between Amphenol ICC and Samtec CLT series connectors?

A: Both maintain 0.079" pitch and 16-position configuration. Samtec CLT series offers higher current rating (4.1A per contact versus 2A), uses Liquid Crystal Polymer insulation instead of plastic, and provides enhanced mechanical features (board guide, pick-and-place options). All meet UL94 V-0 and operating temperature requirements.

Q: Which packaging option should be selected for high-volume production?

A: CLT-108-02-F-D-A-P-TR (cut tape with pick-and-place features) or CLT-108-02-F-D-A-TR (tape-and-reel with board guide) are optimized for automated assembly. Tube packaging (CLT-108-02-F-D-A, CLT-108-02-F-D-BE-A) is suitable for lower-volume or manual assembly applications.

Q: Are bottom-entry variants (CLT-108-02-F-D-BE series) electrically equivalent to standard variants?

A: Yes. Bottom-entry variants maintain identical electrical specifications, pitch, position count, and current rating. The difference is connector orientation relative to the PCB, determined by application layout requirements.

Q: What is the significance of the "-A" suffix in Samtec part numbers?

A: The "-A" suffix indicates inclusion of a board guide feature, which provides improved mechanical alignment and stability during mating operations.

Q: What is the significance of the "-K" suffix in Samtec part numbers?

A: The "-K" suffix indicates pick-and-place features, optimizing the connector for automated assembly equipment.
