Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 55510-306LF are qualified based on the following critical parameters that determine functional equivalence:

• Connector Type & Style: Receptacle, board-to-board configuration
• Position Count & Pitch: 6 positions at 0.079" (2.00mm) mating pitch
• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Material & Finish: Gold-plated mating contacts on phosphor bronze
• Electrical Ratings: Voltage and current capacity within application tolerance
• Environmental Compliance: RoHS and REACH compliance status

The identified substitutes from Hirose Electric Co Ltd (A3-6DA-2SV(71) and A3A-6DA-2SV(71)) meet the core mechanical and electrical parameters. Differences in operating temperature range, current rating, and contact finish thickness are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Operating Temperature Range: The 55510-306LF operates to 125°C, while both Hirose substitutes (A3-6DA-2SV(71) and A3A-6DA-2SV(71)) are rated to 85°C maximum. Applications requiring operation above 85°C are not suitable for these substitutes.

Current Rating Differential: The 55510-306LF is rated for 2A per contact, while the Hirose alternatives are rated for 1A per contact. Applications requiring 2A current capacity must verify that the Hirose parts meet reduced current requirements.

Compliance Status: All three parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity. The Amphenol ICC part is RoHS Compliant, while the Hirose parts are ROHS3 Compliant. Both compliance levels are acceptable for general industrial and medical applications.

Contact Finish Thickness: The 55510-306LF provides 15.0µin (0.38µm) gold plating on mating contacts, compared to 8.00µin (0.203µm) on the Hirose parts. For applications with high mating cycle requirements or corrosive environments, the thicker gold plating of the primary part may provide extended service life.

Mechanical Compatibility: Both Hirose substitutes maintain identical pitch, row spacing, and push-pull fastening, ensuring mechanical interchangeability at the board level. The A3A-6DA-2SV(71) includes a board guide feature not present in the A3-6DA-2SV(71).

Frequently Asked Questions (FAQ)

Q: Can the Hirose A3-6DA-2SV(71) or A3A-6DA-2SV(71) directly replace the Amphenol ICC 55510-306LF?

A: Direct replacement is possible only when application requirements fall within the Hirose part specifications. The critical limiting factors are operating temperature (maximum 85°C for Hirose vs. 125°C for Amphenol ICC) and current rating (1A for Hirose vs. 2A for Amphenol ICC). If your application operates below 85°C and requires maximum 1A per contact, substitution is mechanically and electrically feasible.

Q: What is the difference between A3-6DA-2SV(71) and A3A-6DA-2SV(71)?

A: Both parts share identical electrical and mechanical specifications. The primary difference is the inclusion of a board guide feature in the A3A-6DA-2SV(71) model, which provides additional mechanical stability during mating. Selection between these two depends on whether the board guide feature is required for your application's mechanical design.

Q: Are there any compliance concerns when substituting these parts?

A: Both Hirose parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity, matching the Amphenol ICC part. The Hirose parts carry ROHS3 compliance versus RoHS Compliance on the Amphenol ICC part. Both compliance levels are acceptable for industrial and medical applications. Verify specific compliance requirements for your end application.

Q: How does the gold plating thickness affect connector performance?

A: The Amphenol ICC 55510-306LF provides 15.0µin (0.38µm) gold plating compared to 8.00µin (0.203µm) on the Hirose parts. Thicker gold plating generally provides better corrosion resistance and extended mating cycle life. For applications with frequent mating cycles or exposure to corrosive environments, the thicker plating of the primary part may be preferred.

Q: What are the inventory considerations for these substitutes?

A: The Amphenol ICC 55510-306LF has 1103 units in stock. The Hirose A3-6DA-2SV(71) has 1805 units available, and the A3A-6DA-2SV(71) has 1157 units in stock. Substitute selection may be influenced by inventory availability and lead time requirements.
