Engineering Selection Recommendations

Primary Recommendation: 55510-328LF

The 55510-328LF is the direct successor to the obsolete 55510-328. Both parts share identical electrical and mechanical specifications, with the primary distinction being RoHS compliance status. The 55510-328LF is active in production and available in Tube packaging. This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendation: Samtec MMS-114 Series

The Samtec MMS-114 series (MMS-114-02-L-DV-A, MMS-114-02-L-DV-A-K-TR, MMS-114-02-L-DV-A-TR) provides enhanced current capacity (3.9A per contact versus 2A) and maintains the full operating temperature range (-55°C to 125°C). These parts are ROHS3 compliant and available in multiple packaging formats. The board guide feature and pick-and-place compatibility in certain variants support automated assembly processes.

Alternative Recommendation: Hirose A3 Series

The Hirose A3-28DA-2SV(71) and A3A-28DA-2SV(71) are ROHS3 compliant alternatives with identical mechanical compatibility. These parts operate within a reduced temperature range (-55°C to 85°C) and feature lower current rating (1A). Selection of Hirose alternatives is appropriate only when application requirements do not exceed 85°C maximum operating temperature and 1A current per contact.

Packaging Considerations

Tape & Reel (TR) packaging variants are available from Samtec for high-volume automated assembly. Tube packaging is standard across all manufacturers. Selection between packaging formats depends on production volume and assembly equipment compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use MMS-114-02-L-DV-02 as a direct replacement for 55510-328?

A: The MMS-114-02-L-DV-02 has 27 positions loaded instead of 28. This part is not suitable for applications requiring all 28 positions to be populated. Use only if your application design accommodates a single unloaded position.

Q: What is the difference between Samtec MMS-114-02-F-DV and MMS-114-02-L-DV-A?

A: Both parts meet the core substitution criteria. The primary difference is the contact finish thickness on the mating surface (3.00µin versus 10.0µin) and insulation height specification. Both maintain gold plating and operate across -55°C to 125°C. Selection between these variants depends on specific contact wear requirements and mating cycle expectations.

Q: Are Hirose A3 series parts suitable for my application?

A: Hirose A3 series parts are mechanically and electrically compatible with the 55510-328 for applications operating at or below 85°C and requiring maximum 1A per contact. If your application requires operation above 85°C or exceeds 1A per contact, use Amphenol 55510-328LF or Samtec MMS-114 series instead.

Q: What does "Board Guide" feature mean in the Samtec variants?

A: The board guide feature provides mechanical alignment assistance during connector mating. This feature does not affect electrical compatibility and is optional based on assembly process requirements.

Q: Can I mix packaging formats in production?

A: Yes. Tube and Tape & Reel packaging formats contain identical electrical and mechanical components. Packaging format selection depends solely on assembly equipment compatibility and production volume requirements.

Q: Is the 55510-328LF a true equivalent to the obsolete 55510-328?

A: Yes. The 55510-328LF maintains identical electrical specifications, mechanical dimensions, and performance characteristics. The primary difference is RoHS compliance status (Tin-Lead post finish versus the original specification). This part is the recommended direct replacement.

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

A: Contact finish thickness affects connector durability under repeated mating cycles. Thicker gold plating (10.0µin) provides extended contact life in high-cycle applications. Thinner plating (3.00µin or 8.00µin) is suitable for standard industrial applications with moderate mating cycles.
