Substitute Part Grouping Explanation

Substitute parts for the 150220-2000-RB-WD are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Parameters:

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)
Termination (Solder)
Fastening type (Push-Pull)
Contact finish - mating (Gold)

All three substitute parts meet these core compatibility requirements. Variations in secondary parameters such as contact finish thickness, insulation material, insulation height, and operating temperature range are within acceptable tolerances for rectangular connector substitution.

Engineering Selection Recommendations

All three substitute parts maintain Active product status and UL94 V-0 material flammability compliance, ensuring continued availability and regulatory alignment with the original 150220-2000-RB-WD specification.

A3-20DA-2SV(71) and A3A-20DA-2SV(71) (Hirose Electric): These connectors are functionally equivalent for applications operating within -55°C to 85°C temperature range and 200VAC voltage specification. The A3A-20DA-2SV(71) variant includes board guide features. Both parts are RoHS3 compliant and REACH unaffected. Higher inventory availability (5,243 and 8,250 units respectively) supports supply chain continuity.

M22-6341042 (Harwin Inc.): This connector supports higher current rating (2A versus 1A) and maintains the full -55°C to 105°C operating temperature range of the original part. Voltage rating of 500VAC accommodates the original 500VDC specification. RoHS3 compliance and REACH unaffected status are confirmed. Bottom or top entry configuration provides design flexibility for board layout optimization.

Frequently Asked Questions (FAQ)

Q: Can A3-20DA-2SV(71) or A3A-20DA-2SV(71) be used in applications requiring 105°C operation?

A: No. The Hirose A3 series connectors are rated for -55°C to 85°C maximum operating temperature. Applications requiring 105°C operation must use M22-6341042 or the original 150220-2000-RB-WD.

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

A: Both connectors share identical electrical and mechanical specifications. The A3A variant includes board guide features for enhanced mechanical stability during mating operations. Selection depends on PCB layout requirements and assembly process preferences.

Q: Is M22-6341042 suitable for 500VDC applications?

A: M22-6341042 is rated for 500VAC. For 500VDC applications, use the original 150220-2000-RB-WD or verify voltage specification compatibility with application requirements.

Q: Are all substitute parts compatible with existing mating connectors designed for 150220-2000-RB-WD?

A: Yes. All substitute parts maintain identical pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), number of positions (20), and push-pull fastening type, ensuring mechanical and electrical compatibility with existing mating connectors.

Q: What packaging format is available for each substitute part?

A: A3-20DA-2SV(71), A3A-20DA-2SV(71), and M22-6341042 are supplied in Tube packaging. The original 150220-2000-RB-WD is supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and volume specifications.

Q: Do all parts meet RoHS compliance requirements?

A: The original 150220-2000-RB-WD does not specify RoHS status in provided data. Hirose A3 series parts (A3-20DA-2SV(71) and A3A-20DA-2SV(71)) are RoHS3 compliant. Harwin M22-6341042 is RoHS3 compliant. Verify RoHS compliance requirements for your specific application.
