Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2022B2B3W01 is determined by the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Current and Voltage Ratings: AC 6A at 125V and DC 4A at 30V minimum
• Mounting Type: Panel mount configuration with M12 x 1 bushing thread
• Panel Cutout Dimensions: Circular 12.50mm diameter opening
• Termination Style: Solder lug connections
• Ingress Protection: IP67 rating for sealed operation
• Operating Temperature Range: -30°C to 85°C capability
• Regulatory Compliance: ROHS3 compliance required

The substitute part MN22B2B3W01 is identified as a manufacturer-recommended equivalent from NKK Switches. This part maintains the same base product lineage (M2022B2 series) and shares the core electrical and mechanical specifications necessary for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MN22B2B3W01 is the manufacturer-recommended substitute for the obsolete M2022B2B3W01. Both parts are manufactured by NKK Switches and share identical electrical specifications, mechanical dimensions, and regulatory compliance status.

The primary distinction is product status: the M2022B2B3W01 is obsolete, while the MN22B2B3W01 is active. This transition reflects standard product lifecycle management within the NKK Switches M2022B2 series.

Both parts maintain ROHS3 compliance and carry the same ECCN (EAR99) and HTSUS classification, ensuring regulatory consistency in procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the MN22B2B3W01 directly replace the M2022B2B3W01 in existing designs?

A: Yes. Both parts share identical electrical ratings (6A AC at 125V, 4A DC at 30V), DPDT circuit configuration, panel mount geometry (M12 x 1 bushing, 12.50mm circular cutout), solder lug termination, and IP67 ingress protection. No design modifications are required.

Q: What is the difference between these two part numbers?

A: The M2022B2B3W01 is classified as obsolete, while the MN22B2B3W01 is active production. Both are from the NKK Switches M2022B2 series and maintain identical specifications. The part number change reflects manufacturer product lifecycle management.

Q: Are there packaging differences between the two parts?

A: The M2022B2B3W01 is packaged in standard format, while the MN22B2B3W01 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the M2022B2B3W01 and MN22B2B3W01 are ROHS3 compliant, carry EAR99 ECCN classification, and share the same HTSUS code (8536.50.9065). Regulatory compliance is equivalent.

Q: What operating conditions are supported by the substitute part?

A: The MN22B2B3W01 operates across the same temperature range as the original part (-30°C to 85°C) and maintains IP67 ingress protection for dust-tight, waterproof operation. Electrical life is rated at 25,000 cycles.
