Amphenol ICC 55510-306 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55510-306 is a 6-position receptacle connector from the Minitek® 2.00mm series, designed for surface mount board-to-board applications. This connector features a 0.079" (2.00mm) pitch, gold-plated mating contacts, and operates across -55°C to 125°C with a 2A current rating at 200V. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution eligibility for the 55510-306 is determined by strict alignment with the following core parameters: 6-position configuration, 0.079" (2.00mm) pitch, 2-row layout with 0.079" row spacing, surface mount termination, female socket contact type, gold mating contact finish, push-pull fastening, 2A current rating, and 200V voltage rating. All substitute parts must maintain these electrical and mechanical specifications to ensure direct compatibility in board-to-board applications.

The substitute parts identified fall into two categories: direct manufacturer variants and cross-manufacturer equivalents. Direct variants maintain identical specifications with only packaging or compliance differences. Cross-manufacturer equivalents provide functional equivalence but may include minor parameter variations that remain within acceptable substitution tolerances for this connector class.

Engineering Selection Recommendations

The 55510-306LF is the primary direct substitute, maintaining identical electrical and mechanical specifications while offering active product status and RoHS compliance. This variant is recommended for applications requiring continuity with the original Minitek® 2.00mm series design.

The Hirose A3-6DA-2SV(71) and A3A-6DA-2SV(71) are cross-manufacturer equivalents suitable for applications where the reduced current rating (1A versus 2A) and lower maximum operating temperature (-55°C to 85°C versus -55°C to 125°C) are acceptable. Both Hirose variants provide active product status and ROHS3 compliance. The A3A-6DA-2SV(71) includes a board guide feature not present in the A3-6DA-2SV(71).

Selection between these substitutes depends on application current requirements, thermal environment, and compliance mandates. For applications operating above 85°C or requiring the full 2A current capacity, the 55510-306LF is the appropriate choice. For general-purpose applications within the reduced parameter envelope, either Hirose variant provides equivalent functionality.

Frequently Asked Questions (FAQ)

Q: Can the 55510-306LF be used as a direct replacement for the 55510-306?

A: Yes. The 55510-306LF maintains identical electrical and mechanical specifications, including 6-position configuration, 0.079" (2.00mm) pitch, 2A current rating, 200V voltage rating, and -55°C to 125°C operating temperature. The primary differences are active product status and RoHS compliance.

Q: What are the limitations of using Hirose A3 series connectors as substitutes?

A: The Hirose A3-6DA-2SV(71) and A3A-6DA-2SV(71) have a reduced current rating of 1A (versus 2A) and maximum operating temperature of 85°C (versus 125°C). These parts are suitable only for applications operating within these reduced parameters. All other core specifications—pitch, position count, row spacing, mounting type, and contact configuration—remain compatible.

Q: Are there packaging differences between the substitute parts?

A: The 55510-306 has no specified packaging, while 55510-306LF, A3-6DA-2SV(71), and A3A-6DA-2SV(71) are supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

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

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The A3A-6DA-2SV(71) includes a board guide feature. Selection between them depends on whether the board guide is required for the application.

Q: Are all substitute parts RoHS compliant?

A: The 55510-306 is RoHS non-compliant. The 55510-306LF is RoHS compliant. Both Hirose variants (A3-6DA-2SV(71) and A3A-6DA-2SV(71)) are ROHS3 compliant. Compliance requirements should be verified against application and regulatory mandates.
