Substitute Part Grouping Explanation

Substitution for the 55510-028 is determined by strict alignment of the following critical parameters:

Connector geometry: 28-position receptacle, 0.079" (2.00mm) pitch, 2-row configuration
Electrical interface: Female socket contacts, push-pull fastening, solder termination
Contact specifications: Gold-plated mating surface, phosphor bronze material
Environmental rating: Operating temperature range, flammability compliance (UL94 V-0)
Packaging and compliance: RoHS status and moisture sensitivity level

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalent (Amphenol ICC): The 55510-028LF maintains identical electrical and mechanical specifications with the primary difference being RoHS compliance and active product status.

Cross-Manufacturer Alternatives: Hirose Electric (A3 series), and Samtec (MMS series) provide functionally equivalent 28-position, 2.00mm pitch receptacle connectors with push-pull fastening. These alternatives meet the core mating interface requirements but may differ in insulation material, contact current ratings, and operating temperature ranges as detailed in the parameter comparison.

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer)

The 55510-028LF is the primary substitute for the obsolete 55510-028. Both parts maintain identical electrical and mechanical specifications within the Minitek® 2.00mm series. The 55510-028LF is active in production and RoHS compliant, making it the preferred choice for new designs and ongoing production requiring the original Amphenol ICC connector geometry.

For Cross-Manufacturer Substitution

Hirose Electric A3 series (A3-28DA-2SV(71) and A3A-28DA-2SV(71)) provide equivalent 28-position, 2.00mm pitch receptacle connectors with identical mating interface geometry. These parts are ROHS3 compliant and active. However, the operating temperature range is limited to -55°C to 85°C compared to the original -55°C to 125°C specification, and current rating is 1A versus 2A. The A3A-28DA-2SV(71) variant includes a board guide feature.

Samtec MMS series connectors (MMS-114-02-F-DV, MMS-114-02-L-DV-A, and variants) offer the highest current capacity at 3.9A per contact and maintain the full -55°C to 125°C operating temperature range. These parts use Liquid Crystal Polymer (LCP) insulation and are ROHS3 compliant. Multiple packaging options are available including Tube and Tape & Reel (TR) formats. The MMS-114-02-L-DV-A and MMS-114-02-L-DV-A-K-TR variants include board guide features for enhanced mechanical stability.

Compliance Considerations

All substitute parts listed are ROHS3 compliant or RoHS compliant, addressing the non-compliance status of the original 55510-028. Selection should account for specific application requirements regarding operating temperature range, current capacity, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the 55510-028LF be used as a direct replacement for the 55510-028?

A: Yes. The 55510-028LF maintains identical electrical and mechanical specifications. The primary differences are active product status and RoHS compliance. Both parts are within the Amphenol ICC Minitek® 2.00mm series and share the same 28-position, 2.00mm pitch, push-pull receptacle configuration.

Q: What are the key differences between Amphenol ICC and Hirose Electric A3 series substitutes?

A: The Hirose A3 series maintains the same 28-position, 2.00mm pitch mating interface. However, the operating temperature range is limited to -55°C to 85°C (versus -55°C to 125°C for the original), and current rating is 1A per contact (versus 2A). Insulation material differs: A3 series uses Polyphenylene Sulfide (PPS) versus plastic in the original. Insulation height is also slightly reduced at 0.165" (4.20mm) versus 0.177" (4.50mm).

Q: What advantages do Samtec MMS series connectors offer?

A: Samtec MMS series connectors provide higher current capacity at 3.9A per contact and maintain the full -55°C to 125°C operating temperature range. They use Liquid Crystal Polymer (LCP) insulation for enhanced thermal and chemical resistance. Multiple packaging options are available including Tube and Tape & Reel formats. Board guide variants (MMS-114-02-L-DV-A and MMS-114-02-L-DV-A-K-TR) provide additional mechanical stability.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are RoHS compliant or ROHS3 compliant. The original 55510-028 is RoHS non-compliant. If RoHS compliance is required for your application, any of the listed substitutes will satisfy this requirement.

Q: What packaging options are available for substitute parts?

A: The 55510-028LF is available in Tube packaging. Hirose A3 series parts are available in Tube packaging. Samtec MMS series offers multiple options: standard Tube packaging, Tape & Reel (TR) for automated assembly, and variants with board guide and pick-and-place features. Selection depends on assembly process requirements.

Q: Can I use a substitute part with a lower operating temperature range?

A: The Hirose A3 series is limited to -55°C to 85°C. If your application requires operation at temperatures above 85°C up to 125°C, the Amphenol ICC 55510-028LF or Samtec MMS series are required. Verify your specific application temperature requirements before selecting a substitute.

Q: What is the significance of the board guide feature in MMS variants?

A: The board guide feature (present in MMS-114-02-L-DV-A, MMS-114-02-L-DV-A-K-TR, and MMS-114-02-L-DV-A-TR) provides mechanical alignment and stability during mating. This feature is beneficial for applications requiring precise connector positioning or high-reliability board-to-board connections.
