Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SD3W01-BA is determined by the following critical parameters:

• Circuit Configuration: SPDT topology is mandatory for functional equivalence
• Switch Function: On-Momentary operation must be maintained
• Current Rating: AC rating of 6A and DC rating of minimum 3A required
• Voltage Rating: AC rating of 125V and DC rating of minimum 30V required
• Mounting Type: Panel Mount, Rear configuration required
• Termination Style: Solder Lug termination required
• Panel Cutout Diameter: Circular 6.35mm to 6.50mm acceptable within mechanical tolerance
• Regulatory Compliance: ROHS3 compliance required

The substitute parts identified—MBN15SD3W01-BA, MPA106F, and MPE106F—satisfy these core electrical and mechanical parameters, enabling direct functional replacement in applications previously utilizing the MB2011SD3W01-BA.

Parameter Comparison

Engineering Selection Recommendations

MBN15SD3W01-BA (NKK Switches, Active Status): This NKK Switches alternative maintains manufacturer continuity and active product status. Detailed electrical and mechanical specifications are not fully provided in available documentation; verification of circuit configuration and current ratings against application requirements is necessary prior to implementation.

MPA106F (TE Connectivity ALCOSWITCH, Active Status): This substitute provides confirmed SPDT configuration with 6A AC and 4A DC capacity, meeting or exceeding the original part's electrical requirements. The 28V DC rating is marginally lower than the original 30V specification. Operating temperature range is reduced to -20°C to 80°C. Electrical life rating of 50,000 cycles exceeds the original specification. ROHS3 compliance and MSL 1 rating are confirmed. REACH status is listed as vendor undefined.

MPE106F (TE Connectivity ALCOSWITCH, Active Status): This substitute offers identical electrical specifications to MPA106F with confirmed SPDT configuration, 6A AC and 4A DC capacity, and 50,000-cycle electrical life. Operating temperature range is -20°C to 80°C. Ingress protection is specified as splash proof, providing enhanced environmental sealing compared to the original IP67 specification. ROHS3 compliance and MSL 1 rating are confirmed. REACH status is listed as affected.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011SD3W01-BA?

A: Both MPA106F and MPE106F satisfy the core electrical parameters: SPDT circuit, 6A AC rating, minimum 4A DC rating, 125V AC rating, and solder lug termination. The 28V DC rating of these substitutes is 2V lower than the original 30V specification; applications operating at or below 28V DC are fully compatible. Panel cutout diameter difference of 0.15mm (6.35mm vs. 6.50mm) falls within standard mechanical tolerance for circular panel mounts.

Q: What are the temperature operating range differences?

A: The original MB2011SD3W01-BA operates from -30°C to 85°C. Both MPA106F and MPE106F operate from -20°C to 80°C. Applications requiring operation below -20°C or above 80°C cannot use these substitutes.

Q: How do electrical life ratings compare?

A: The original part is rated for 25,000 electrical cycles. Both MPA106F and MPE106F are rated for 50,000 electrical cycles, providing extended operational life in high-cycle applications.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications and ratings. MPE106F specifies splash proof ingress protection, whereas MPA106F does not specify ingress protection rating. For applications requiring enhanced environmental sealing, MPE106F is the preferred selection.

Q: Is MBN15SD3W01-BA a viable substitute?

A: MBN15SD3W01-BA maintains NKK Switches manufacturer continuity and active product status. However, detailed electrical and mechanical specifications are not provided in available documentation. Direct comparison against application requirements cannot be completed without access to complete technical specifications.

Q: Are all substitutes ROHS3 compliant?

A: Yes. MB2011SD3W01-BA, MBN15SD3W01-BA, MPA106F, and MPE106F are all ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.
