Engineering Selection Recommendations

For Direct Amphenol ICC Replacement: Select 55508-334LF when maintaining the Minitek® 2.00mm series is required. This part is the active production equivalent with identical mechanical and electrical specifications. RoHS compliance and active product status make it suitable for new designs. Tin post finish replaces the original tin-lead composition.

For Cross-Manufacturer Substitution: Samtec CLT-117-02 series parts provide full electrical and mechanical compatibility with enhanced performance characteristics. All variants are active status and ROHS3 compliant. Selection within this series depends on specific application requirements:

CLT-117-02-F-D: Standard top-entry configuration
CLT-117-02-F-D-A: Includes board guide feature
CLT-117-02-F-D-BE: Bottom-entry configuration for space-constrained layouts
CLT-117-02-F-D-BE-A: Bottom-entry with board guide
CLT-117-02-F-D-A-P and CLT-117-02-F-D-A-P-TR: Include pick-and-place features for automated assembly

All CLT-117-02 variants support higher current capacity (4.1A per contact versus 2A) and use liquid crystal polymer insulation, providing improved dimensional stability and thermal performance compared to plastic insulation.

Packaging Considerations:

Tube packaging: Standard for manual assembly workflows
Tape & Reel (TR): Required for automated pick-and-place assembly
Bulk packaging: Available for specific configurations

Frequently Asked Questions (FAQ)

Q: Can CLT-117-02 series connectors directly replace 55508-334 in existing designs? A: Yes. All CLT-117-02 variants maintain the critical electrical and mechanical parameters: 34 positions, 0.079" (2.00mm) pitch, 2-row layout, female socket contacts, gold mating finish, surface mount termination, and push-pull fastening. Board-to-board style and operating temperature range are identical.

Q: What is the difference between standard and bottom-entry CLT-117-02 configurations? A: Bottom-entry variants (CLT-117-02-F-D-BE series) orient the mating interface perpendicular to the board surface, enabling vertical stacking in space-constrained applications. Standard variants (CLT-117-02-F-D series) use horizontal mating orientation. Electrical performance is identical.

Q: Does the reduced gold plating thickness on CLT-117-02 parts (3.00µin versus 15.0µin) affect reliability? A: No. Both thicknesses meet industry standards for gold-plated contacts in this connector class. The 3.00µin specification on CLT-117-02 parts is sufficient for the specified operating conditions and current ratings.

Q: Why do CLT-117-02 parts have higher current ratings (4.1A per contact) than the original 55508-334 (2A)? A: The CLT-117-02 series uses liquid crystal polymer insulation and optimized contact geometry, enabling higher current capacity. This represents an improvement over the original design and does not create compatibility issues in applications requiring 2A or less.

Q: Is 55508-334LF preferred over CLT-117-02 series for new designs? A: Selection depends on application requirements. 55508-334LF maintains the original Minitek® series and plastic insulation. CLT-117-02 series offers enhanced performance (higher current, LCP insulation) and broader packaging options. Both are active, RoHS compliant, and fully compatible.

Q: What packaging format should be selected for automated assembly? A: Tape & Reel (TR) packaging is required for automated pick-and-place assembly. Tube packaging is suitable for manual assembly. Verify your assembly equipment compatibility before selecting packaging format.

Q: Are all substitute parts listed compatible with the original mating connector? A: Yes. All listed substitutes maintain the 0.079" (2.00mm) pitch, 34-position configuration, and push-pull fastening mechanism required for mating with the original connector series.
