A3-32DA-2SV Equivalent & Substitute Parts

Part Overview

The A3-32DA-2SV is a 32-position receptacle connector manufactured by Hirose Electric Co Ltd, designed for surface mount applications with 0.079" (2.00mm) pitch. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 85°C. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts maintain core electrical and mechanical compatibility while offering active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the A3-32DA-2SV is determined by strict alignment with the following core parameters: 32-position configuration, 0.079" (2.00mm) mating pitch, 2-row layout with 0.079" row spacing, surface mount termination, push-pull fastening, gold mating contact finish, and UL94 V-0 flammability rating. All identified substitutes maintain these critical mechanical and electrical specifications. Variations in operating temperature range, voltage rating, contact finish thickness, insulation material, and packaging format are permitted within the substitute group, as these do not affect board-level compatibility or connector mating functionality. The A3-32DA-2SV(71) variant from Hirose represents a direct form-fit-function replacement with improved RoHS3 compliance. The 3M 1502 series (150232-2000-RB-WE, 150232-2020-RB, 150232-2020-RB) and Amphenol ICC Minitek® 2.00mm series (55510-032LF, 55510-132LF) provide cross-manufacturer alternatives meeting identical positional and pitch requirements.

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete A3-32DA-2SV, the A3-32DA-2SV(71) from Hirose provides identical mechanical and electrical specifications with the advantage of active product status and RoHS3 compliance. This variant maintains the original operating temperature range and voltage rating while ensuring long-term supply availability.

For new designs or applications where extended operating temperature range is beneficial, the 3M 1502 series connectors (150232-2000-RB-WE, 150232-2020-RB, 150232-2020-RB-WE) support operation to 105°C and feature higher voltage rating (500VDC). These parts are RoHS compliant and available in multiple packaging formats. The 150232-2020-RB-WE variant includes both board guide and pick-and-place features for automated assembly.

The Amphenol ICC Minitek® 2.00mm series (55510-032LF, 55510-132LF) offers the highest operating temperature range (-55°C to 125°C) and increased current rating (2A). These parts are RoHS compliant and suitable for industrial and medical applications. The 55510-132LF provides thicker gold plating (30.0µin) compared to the 55510-032LF (1.97µin).

Selection should prioritize product status (all substitutes are active), RoHS compliance requirements, packaging format compatibility with assembly processes, and operating temperature/voltage margins for the target application.

Frequently Asked Questions (FAQ)

Q: Can the A3-32DA-2SV be directly replaced with A3-32DA-2SV(71)?

A: Yes. The A3-32DA-2SV(71) maintains identical connector geometry, pitch, position count, row spacing, mounting type, and termination method. The primary differences are active product status and RoHS3 compliance. This is a direct form-fit-function replacement.

Q: What are the key differences between Hirose A3 series and 3M 1502 series substitutes?

A: Both maintain the critical 32-position, 0.079" pitch, 2-row configuration and push-pull fastening. The 3M 1502 series supports higher operating temperature (105°C vs. 85°C) and higher voltage rating (500VDC vs. 200VAC). Insulation height varies slightly (0.183" for 3M vs. 0.165" for Hirose). Contact finish thickness is thicker on 3M parts (30.0µin vs. 8.00µin).

Q: Are Amphenol ICC Minitek® 2.00mm connectors compatible with the A3-32DA-2SV?

A: Yes, for board-level mating compatibility. The 55510-032LF and 55510-132LF maintain identical pitch, position count, row spacing, and push-pull fastening. Amphenol parts support higher operating temperature (125°C) and higher current rating (2A). Insulation height is 0.177" compared to 0.165" for the original part.

Q: What packaging options are available for substitutes?

A: A3-32DA-2SV(71) is supplied in Tube. The 3M 1502 series offers Tape & Reel (TR) for 150232-2000-RB-WE and 150232-2020-RB-WE, and Bulk for 150232-2020-RB. Amphenol ICC Minitek® parts are supplied in Tube.

Q: Do all substitute parts meet UL94 V-0 flammability requirements?

A: Yes. All substitute parts listed maintain UL94 V-0 material flammability rating, matching the original A3-32DA-2SV specification.

Q: Which substitute offers the best compliance profile?

A: All active substitutes are RoHS compliant. The A3-32DA-2SV(71) specifically carries RoHS3 compliance. All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Can substitutes be used interchangeably in existing designs?

A: Mechanical and electrical interchangeability is confirmed for all listed substitutes based on shared core parameters. However, minor variations in insulation height and contact finish thickness should be evaluated against specific PCB layout and mating connector specifications to ensure optimal performance.
