Substitute Part Grouping Explanation

Substitution eligibility for the 150220-2000-RB is determined by the following critical parameters:

Core Compatibility Requirements:

Connector type: Receptacle
Contact type: Female socket
Number of positions: 20
Pitch - mating: 0.079" (2.00mm)
Number of rows: 2
Row spacing - mating: 0.079" (2.00mm)
Mounting type: Surface mount
Fastening type: Push-pull
Contact finish - mating: Gold
Termination: Solder

Allowable Variations: Substitute parts may differ in operating temperature range, voltage rating, current rating, insulation material, contact material composition, and contact finish thickness, provided the application requirements do not exceed the substitute part's electrical or thermal specifications. Packaging format (bulk versus tube) does not affect functional compatibility.

The three identified substitutes—A3-20DA-2SV(71), A3A-20DA-2SV(71), and M22-6341042—meet all core compatibility requirements and are suitable for applications where the specified parameter variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can A3-20DA-2SV(71) or A3A-20DA-2SV(71) be used in place of 150220-2000-RB in all applications?

A: No. The Hirose A3 series parts are limited to 85°C maximum operating temperature and 200VAC maximum voltage rating. Use these substitutes only when your application does not exceed these specifications. If your design requires operation above 85°C or 500VDC, use 150220-2000-RB or M22-6341042.

Q: What is the difference between A3-20DA-2SV(71) and A3A-20DA-2SV(71)?

A: Both parts are electrically and mechanically identical. The A3A variant includes a board guide feature. Select A3A-20DA-2SV(71) if mechanical alignment guidance is required during assembly.

Q: Can M22-6341042 replace 150220-2000-RB in high-current applications?

A: M22-6341042 supports 2A current rating versus 1A for 150220-2000-RB. It is suitable for applications requiring higher current capacity. Verify that the bottom or top entry configuration matches your PCB layout requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. 150220-2000-RB is RoHS Compliant. A3-20DA-2SV(71), A3A-20DA-2SV(71), and M22-6341042 are all ROHS3 Compliant.

Q: Does packaging format (bulk versus tube) affect connector performance?

A: No. Packaging format does not affect electrical or mechanical performance. 150220-2000-RB is supplied in bulk; substitute parts are supplied in tube packaging. Select based on your procurement and handling requirements.

Q: What is the mated stacking height for these connectors?

A: 150220-2000-RB and M22-6341042 do not specify mated stacking heights. A3-20DA-2SV(71) and A3A-20DA-2SV(71) specify 5.1mm and 6mm mated stacking heights. Verify stacking height requirements for your application before substitution.
