953246-2000-AR-TP Equivalent & Substitute Parts

Part Overview

The 3M 953246-2000-AR-TP is a 46-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 product is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 953246-2000-AR-TP is determined by the following critical parameters:

Connector configuration: 46-position receptacle with 2-row arrangement
Pitch specification: 0.079" (2.00mm) mating pitch and row spacing
Mounting technology: Surface mount with solder termination
Contact system: Female socket with gold mating finish
Mechanical interface: Push-pull fastening mechanism
Electrical performance: 1A current rating and voltage compatibility
Environmental compliance: UL94 V-0 flammability rating

The Molex 0791091022 satisfies all critical substitution criteria within the allowed parameter set.

Engineering Selection Recommendations

The Molex 0791091022 is an active product with ROHS3 compliance and REACH unaffected status, providing supply chain continuity for the obsolete 3M 953246-2000-AR-TP. Both connectors share identical mechanical and electrical core specifications across pitch, position count, mounting method, and contact configuration.

The Molex substitute offers an extended operating temperature range (-55°C to 125°C versus -40°C to 105°C) and maintains UL94 V-0 flammability certification. The voltage rating difference (125V versus 1000VDC) requires application-level verification to confirm compatibility with system requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0791091022 directly replace the 3M 953246-2000-AR-TP in existing designs?

A: Direct mechanical and electrical substitution is supported for applications operating within the Molex voltage specification of 125V. The identical pitch (0.079"), position count (46), row configuration (2), and contact finish (gold) ensure physical and electrical compatibility. Verify your application voltage requirements against the 125V rating.

Q: What are the key differences between these connectors?

A: The primary differences are product status (3M obsolete, Molex active), operating temperature range (Molex extended to -55°C to 125°C), voltage rating (Molex 125V versus 3M 1000VDC), and insulation material (Molex uses glass-filled LCP versus 3M thermoplastic). Contact material also differs (Molex phosphor bronze versus 3M copper alloy).

Q: Are there packaging considerations for procurement?

A: The Molex 0791091022 is supplied in tube packaging. Verify your assembly process compatibility with this packaging format and confirm inventory availability against your production schedule.

Q: Does the Molex substitute maintain compliance certifications?

A: Yes. The Molex 0791091022 is ROHS3 compliant, REACH unaffected, and maintains UL94 V-0 flammability rating, matching the compliance profile of the original 3M connector.
