Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 55508-024LF

The 55508-024LF is the direct successor to the obsolete 55508-024. It maintains identical electrical and mechanical specifications while achieving RoHS compliance. This part is the preferred choice for direct replacement in existing designs, as it requires no layout or assembly modifications.

Secondary Recommendations: Samtec CLT Series

The Samtec CLT-112-02-F-D and its variants (CLT-112-02-F-D-A, CLT-112-02-F-D-A-K-TR, CLT-112-02-F-D-A-P, CLT-112-02-F-D-A-P-TR, CLT-112-02-F-D-A-TR, CLT-112-02-F-D-BE, CLT-112-02-F-D-BE-A) are functionally equivalent cross-manufacturer alternatives. All CLT variants meet the core dimensional and electrical requirements. Selection among CLT variants depends on packaging requirements: tube packaging for standard applications, tape & reel (TR) for automated assembly, and bottom entry (BE) variants for specific board layout constraints. All CLT parts are ROHS3 compliant and active products.

Alternative Consideration: Molex 0872632423

The Molex Milli-Grid 87263 series part 0872632423 is a bottom entry receptacle with matching pitch and position count. This part is suitable for applications where bottom entry configuration is required. Note that the current rating is 1A per contact, lower than the original 2A specification, and the operating temperature maximum is 105°C versus 125°C for the original part.

Compliance Status:

All recommended substitutes are ROHS3 compliant and carry active product status, ensuring long-term availability and manufacturing support. The original 55508-024 is RoHS non-compliant and obsolete.

Frequently Asked Questions (FAQ)

Q: Can I use CLT-112-02-F-D-BE as a direct replacement for 55508-024?

A: Yes, the CLT-112-02-F-D-BE is mechanically and electrically compatible. The primary difference is the bottom entry connector type versus the standard top entry of the original part. This affects board layout and mating connector orientation. Verify that your mating connector is compatible with bottom entry configuration before substitution.

Q: What is the difference between CLT-112-02-F-D-A and CLT-112-02-F-D-A-K-TR?

A: Both parts are electrically and mechanically identical. The difference is packaging: CLT-112-02-F-D-A is supplied in tube packaging, while CLT-112-02-F-D-A-K-TR is supplied in tape & reel format with pick-and-place features. Tape & reel packaging is optimized for automated assembly processes.

Q: Why does the Molex 0872632423 have a lower current rating?

A: The Molex part is rated at 1A per contact versus 2A for the original Amphenol part. This reflects different contact design and material specifications. If your application requires 2A per contact, the Molex part is not suitable. Samtec CLT series parts are rated at 4.1A per contact and exceed the original specification.

Q: Is the Amphenol 55508-024LF available in tape & reel packaging?

A: The 55508-024LF is supplied in tube packaging only. For tape & reel packaging, select a Samtec CLT variant with TR designation (CLT-112-02-F-D-A-K-TR, CLT-112-02-F-D-A-P-TR, or CLT-112-02-F-D-A-TR).

Q: What does the "A" designation in CLT part numbers indicate?

A: The "A" designation indicates the presence of a board guide feature, which provides additional mechanical stability during mating and unmating operations.

Q: Are all substitute parts UL94 V-0 rated?

A: Yes, all recommended substitute parts carry UL94 V-0 material flammability rating, matching the original specification.

Q: Can I mix and match CLT variants in the same assembly?

A: Yes, all CLT-112-02-F-D variants are electrically and mechanically interchangeable. Mixing variants is acceptable provided the connector type (standard versus bottom entry) is consistent with your board layout and mating connector design.
