Engineering Selection Recommendations

The 55510-022 is obsolete and requires substitution. The Amphenol ICC 55510-022LF is the direct equivalent from the same manufacturer and series, maintaining identical electrical and mechanical specifications while offering active product status and RoHS compliance. This part is the primary recommendation for direct replacement.

For applications requiring active product status with extended compliance certifications, the Samtec MMS-111-02-F-DV-A and TLE series connectors (TLE-111-01-G-DV-A-TR and TLE-111-01-G-DV-P-TR) provide ROHS3 compliance and higher current ratings per contact. The TLE series offers pass-through connector functionality for applications requiring signal routing through the connector body.

The Molex 0791098410 and 3M 150222-2020-RB are functionally compatible alternatives with active status and RoHS compliance. The 3M part supports higher voltage ratings (500VDC) and includes board guide features. The Molex part includes pick-and-place features for automated assembly.

Selection should prioritize the 55510-022LF for direct replacement in existing designs. Alternative manufacturers should be selected based on specific application requirements for current capacity, voltage rating, connector style (standard vs. pass-through), and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the 55510-022LF directly replace the obsolete 55510-022?

A: Yes. The 55510-022LF maintains identical core specifications: 22-position receptacle, 0.079" (2.00mm) pitch, 2-row configuration, surface mount solder termination, push-pull fastening, and gold-plated contacts. The primary difference is RoHS compliance and active product status.

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

A: The Amphenol ICC 55510-022LF is the direct series equivalent. Samtec MMS and TLE series connectors offer higher current ratings per contact (3.2–3.9A vs. 2A), LCP insulation material, and pass-through connector options in the TLE series. All maintain the 0.079" (2.00mm) pitch and 22-position configuration.

Q: Are there voltage or current limitations when substituting?

A: The original 55510-022 is rated for 2A at 200V. The Molex 0791098410 and 3M 150222-2020-RB are rated for 1A, which is lower than the original specification. The Samtec parts support higher current per contact. The 3M part supports 500VDC, exceeding the original 200V rating. Application requirements must be verified against selected substitute specifications.

Q: What is the difference between standard and pass-through connectors?

A: The Samtec TLE series offers pass-through connector functionality, allowing signals to route through the connector body. Standard receptacles (55510-022LF, MMS-111-02-F-DV-A) terminate at the connector. Pass-through variants are specified for applications requiring signal continuity through the connector assembly.

Q: How do packaging formats affect component selection?

A: The original 55510-022 packaging is not specified. Substitutes are available in Tube (55510-022LF, MMS-111-02-F-DV-A), Tape & Reel (0791098410, TLE series), and Tray (150222-2020-RB) formats. Packaging selection depends on assembly process requirements and volume specifications.

Q: Are all substitutes RoHS compliant?

A: The original 55510-022 is RoHS non-compliant. The 55510-022LF is RoHS Compliant. The Molex 0791098410, Samtec MMS-111-02-F-DV-A, and both Samtec TLE variants are ROHS3 Compliant. The 3M 150222-2020-RB is RoHS Compliant. Regulatory requirements must be confirmed for your application.

Q: What insulation material differences exist among substitutes?

A: The original 55510-022 uses plastic insulation. The 55510-022LF maintains plastic insulation. Molex 0791098410 uses Liquid Crystal Polymer (LCP) glass-filled material. The 3M part uses thermoplastic. Samtec parts use Liquid Crystal Polymer (LCP). LCP materials offer improved thermal and chemical resistance compared to standard plastic.
