953232-2000-AR-TP Equivalent & Substitute Parts

Part Overview

The 3M 953232-2000-AR-TP is a 32-position rectangular 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 -40°C to 105°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the 953232-2000-AR-TP is based on the following critical parameters that must align:

32-position configuration with 0.079" (2.00mm) pitch
2-row layout with 0.079" (2.00mm) row spacing
Receptacle connector with female socket contacts
Surface mount termination with push-pull fastening
Gold-plated mating contacts
1A current rating capability
UL94 V-0 flammability compliance

The Hirose Electric A3-32DA-2SV(71) and A3A-32DA-2SV(71) connectors satisfy these core substitution criteria. Both are active-status parts with identical mechanical and electrical configurations matching the 953232-2000-AR-TP footprint and contact arrangement.

Engineering Selection Recommendations

Both A3-32DA-2SV(71) and A3A-32DA-2SV(71) are active-status alternatives to the obsolete 953232-2000-AR-TP. The Hirose parts provide ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements.

The A3A-32DA-2SV(71) includes a board guide feature and is available in higher inventory (1025 pcs). The A3-32DA-2SV(71) is the base variant without board guide, with 838 pcs in stock.

Both substitutes operate at -55°C to 85°C, which covers the lower end of the original part's temperature range. The voltage rating difference (200VAC versus 1000VDC) reflects the Hirose design specification and must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can A3-32DA-2SV(71) and A3A-32DA-2SV(71) be used interchangeably with 953232-2000-AR-TP?

A: Both Hirose parts match the critical substitution parameters: 32-position configuration, 0.079" pitch, 2-row layout, surface mount termination, push-pull fastening, and gold-plated contacts. The primary difference is the board guide feature in the A3A variant. Selection depends on mechanical design requirements.

Q: What is the difference between A3-32DA-2SV(71) and A3A-32DA-2SV(71)?

A: The A3A-32DA-2SV(71) includes a board guide feature for enhanced mechanical alignment. Both parts are electrically and mechanically equivalent otherwise, with identical pitch, row spacing, contact configuration, and current/voltage ratings.

Q: Are there temperature range considerations when substituting?

A: The original 953232-2000-AR-TP operates -40°C to 105°C. The Hirose substitutes operate -55°C to 85°C. Applications requiring operation above 85°C or below -55°C must be evaluated separately.

Q: What packaging is available for the substitute parts?

A: Both A3-32DA-2SV(71) and A3A-32DA-2SV(71) are supplied in tube packaging.

Q: Are the substitute parts RoHS compliant?

A: Yes, both A3-32DA-2SV(71) and A3A-32DA-2SV(71) are ROHS3 compliant and REACH unaffected.
