Engineering Selection Recommendations

The 3M 153220-2020-RB-WC is the designated substitute for the obsolete 956220-2000-AR-PR. Selection of the substitute is supported by the following factors:

Product Status: The 153220-2020-RB-WC maintains active production status, ensuring availability and supply chain continuity compared to the obsolete 956220-2000-AR-PR.

Compliance & Certifications: Both connectors meet UL94 V-0 flammability requirements. The 153220-2020-RB-WC carries ROHS3 compliance certification, meeting current regulatory standards.

Mechanical Compatibility: Identical pitch (0.079"), row configuration (2 rows), and surface mount termination ensure direct mechanical substitution without PCB redesign.

Electrical Performance: Both connectors support 1A current rating and UL94 V-0 material flammability. The 956220-2000-AR-PR operates at 1000VDC while the 153220-2020-RB-WC operates at 500VDC. Application voltage requirements must be evaluated against this difference.

Temperature Range: The 153220-2020-RB-WC extends the lower operating temperature to -55°C compared to -40°C for the 956220-2000-AR-PR, providing broader thermal coverage.

Insulation Material: The 153220-2020-RB-WC uses Liquid Crystal Polymer (LCP) glass-filled material versus thermoplastic in the original part, offering improved thermal and mechanical properties.

Frequently Asked Questions (FAQ)

Q: Can the 3M 153220-2020-RB-WC directly replace the 956220-2000-AR-PR without PCB modification?

A: Yes. Both connectors share identical pitch (0.079"), row count (2), row spacing (0.079"), and surface mount termination. No PCB layout changes are required for mechanical substitution.

Q: What is the voltage rating difference between these connectors?

A: The 956220-2000-AR-PR is rated for 1000VDC, while the 153220-2020-RB-WC is rated for 500VDC. Applications requiring voltages above 500VDC must retain the original part or identify alternative substitutes rated for higher voltages.

Q: Does the insulation height difference affect compatibility?

A: The 153220-2020-RB-WC has an insulation height of 0.129" (3.28mm) compared to 0.110" (2.79mm) for the 956220-2000-AR-PR. PCB clearance and mating connector geometry must be evaluated to confirm physical fit in the application.

Q: What packaging is available for the substitute part?

A: The 153220-2020-RB-WC is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are both connectors RoHS compliant?
