Engineering Selection Recommendations

Amphenol ICC Direct Equivalent:

The 55508-134LF is the active production equivalent of the obsolete 55508-134. Both parts share identical electrical and mechanical specifications with the exception of contact finish post material (Tin-Lead vs. Tin) and RoHS compliance status. The 55508-134LF is RoHS Compliant and maintains full compatibility with the original design. This part is the primary choice for direct replacement in new production and maintenance applications.

Samtec CLT-117 Series Cross-Manufacturer Alternatives:

The Samtec CLT-117-02 series provides functionally equivalent receptacle connectors with the following distinctions:

All CLT-117-02 variants are Active products with ROHS3 Compliant status
Current rating is 4.1A per contact, exceeding the 2A specification of the original part
Insulation material is Liquid Crystal Polymer (LCP) instead of plastic, providing enhanced thermal and chemical resistance
Insulation height is 0.083" (2.10mm) versus 0.091" (2.30mm) on the original part
Contact finish thickness on mating surfaces is 3.00µin (0.076µm) versus 30.0µin (0.76µm)

Selection among CLT-117-02 variants depends on application requirements:

CLT-117-02-F-D: Base configuration without additional features
CLT-117-02-F-D-A: Includes board guide feature
CLT-117-02-F-D-A-P: Adds pick-and-place feature to board guide configuration
CLT-117-02-F-D-A-P-TR: Pick-and-place and board guide in tape & reel packaging
CLT-117-02-F-D-A-TR: Board guide in tape & reel packaging
CLT-117-02-F-D-BE: Bottom entry configuration without additional features
CLT-117-02-F-D-BE-A: Bottom entry with board guide
CLT-117-02-F-D-BE-A-K: Bottom entry with board guide and pick-and-place
CLT-117-02-F-D-BE-A-K-TR: Bottom entry with board guide, pick-and-place, and tape & reel packaging

Bottom entry variants (CLT-117-02-F-D-BE series) are suitable for applications requiring connector access from the board underside. Standard entry variants (CLT-117-02-F-D series) are suitable for top-side access applications.

Frequently Asked Questions (FAQ)

Q: Can the 55508-134LF be used as a direct replacement for the 55508-134?

A: Yes. The 55508-134LF is the active production equivalent with identical connector geometry, pitch, position count, and electrical ratings. The primary differences are RoHS compliance status and contact finish post material, both of which are compatible with the original design requirements.

Q: What are the key differences between Amphenol ICC and Samtec alternatives?

A: Amphenol ICC 55508-134LF maintains the original plastic insulation material and 2A current rating. Samtec CLT-117-02 series uses Liquid Crystal Polymer insulation and provides 4.1A per contact current rating. Both meet the same pitch, position count, and operating temperature specifications. The choice depends on whether enhanced thermal performance and higher current capacity are required.

Q: Does insulation height variation affect board layout compatibility?

A: The insulation height difference between the original part (0.091" / 2.30mm) and Samtec alternatives (0.083" / 2.10mm) is 0.008" (0.20mm). This variation may affect mated stacking height and clearance calculations in densely packed board designs. Verify board layout constraints before substitution.

Q: What is the significance of contact finish thickness differences?

A: The original part specifies 30.0µin (0.76µm) gold plating on mating contacts, while Samtec alternatives specify 3.00µin (0.076µm). Both thicknesses provide adequate corrosion protection and electrical conductivity for the specified 2A to 4.1A current range. The thinner plating on Samtec parts is standard for high-reliability applications and does not compromise performance.

Q: When should bottom entry (BE) variants be selected?

A: Bottom entry variants (CLT-117-02-F-D-BE series) are specified when the connector must be accessed from the underside of the PCB. Standard entry variants (CLT-117-02-F-D series) are used for top-side access. Board layout and assembly process requirements determine the appropriate entry configuration.

Q: What do the board guide and pick-and-place features provide?

A: Board guide features (-A suffix) provide mechanical alignment during mating. Pick-and-place features (-P or -K suffix) facilitate automated assembly equipment handling. These features do not affect electrical performance but improve manufacturing efficiency and assembly reliability.

Q: Are tape & reel packaging options compatible with tube packaging?

A: Tape & reel (-TR suffix) and tube packaging formats contain identical connector components. The packaging difference affects only storage, handling, and automated assembly compatibility. Electrical and mechanical specifications remain identical across packaging formats.

Q: What RoHS compliance status should be selected for new designs?

A: RoHS Compliant (55508-134LF) and ROHS3 Compliant (CLT-117-02 series) variants are suitable for applications subject to RoHS regulations. The original 55508-134 is RoHS non-compliant and should not be used in new designs targeting regulated markets.
