Amphenol ICC 55510-308 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55510-308 is an 8-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount board-to-board applications. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 125°C. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

8-position configuration with 0.079" (2.00mm) pitch and 2-row layout
Surface mount termination with solder connection
Receptacle connector type with female socket contacts
Push-pull fastening mechanism
Gold-plated mating contacts
UL94 V-0 flammability rating
Phosphor bronze contact material
Square contact geometry

The substitute parts listed below meet these electrical and mechanical requirements. Variations in secondary parameters (contact finish thickness, insulation material, operating temperature range, current rating) do not preclude substitution when the core parameters align.

Engineering Selection Recommendations

All substitute parts maintain compatibility with the 55510-308 through alignment of core electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

Hirose A3-8DA-2SV(71) and A3A-8DA-2SV(71): Both are active Hirose products with ROHS3 compliance. The A3A variant includes a board guide feature. Operating temperature is limited to -55°C to 85°C, and current rating is 1A per contact. These parts are suitable for applications where the reduced temperature range and current rating are acceptable.

Samtec TLE-104-01-G-DV-A-P and TLE-104-01-G-DV-A-P-TR: Both are active Samtec products with ROHS3 compliance, higher current rating (3.2A per contact), and full operating temperature range (-55°C to 125°C) matching the original part. The TLE-104-01-G-DV-A-P-TR variant is supplied in Tape & Reel packaging, suitable for automated assembly. Both include board guide and pick-and-place features. These parts are recommended for applications requiring the full temperature range and higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A3-8DA-2SV(71) be used as a direct replacement for the 55510-308?

A: Yes, the A3-8DA-2SV(71) meets the core substitution criteria: 8-position, 0.079" pitch, 2-row layout, surface mount, receptacle type, female socket contacts, push-pull fastening, and gold-plated mating contacts. However, the operating temperature range is limited to -55°C to 85°C compared to the original -55°C to 125°C, and current rating is 1A versus 2A. Verify application requirements before selection.

Q: What is the difference between the Samtec TLE-104-01-G-DV-A-P and TLE-104-01-G-DV-A-P-TR?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: TLE-104-01-G-DV-A-P is supplied in Tube packaging, while TLE-104-01-G-DV-A-P-TR is supplied in Tape & Reel format. Tape & Reel packaging is optimized for high-volume automated assembly processes.

Q: Are all substitute parts RoHS compliant?

A: The Hirose A3-8DA-2SV(71), A3A-8DA-2SV(71), and both Samtec TLE variants are ROHS3 compliant. The original 55510-308 is RoHS non-compliant. If RoHS compliance is required for your application, use one of the substitute parts.

Q: Which substitute part has the highest current rating?

A: The Samtec TLE-104-01-G-DV-A-P and TLE-104-01-G-DV-A-P-TR both support 3.2A per contact, exceeding the original 55510-308 rating of 2A and the Hirose alternatives at 1A per contact.

Q: Can I use the Hirose A3A-8DA-2SV(71) instead of the A3-8DA-2SV(71)?

A: Yes. Both are electrically and mechanically equivalent. The A3A variant includes a board guide feature. Selection depends on whether the board guide is beneficial for your mechanical design.
