MB2011SD3W01-BC Equivalent & Substitute Parts

Part Overview

The MB2011SD3W01-BC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a rated capacity of 6A at 125V AC and 3A at 30V DC. This panel-mount rear component utilizes a red round button actuator with solder lug termination and IP67 ingress protection. The product is classified as obsolete, necessitating identification of functionally equivalent active alternatives for new designs and ongoing applications.

The substitute parts identified meet or exceed the electrical performance requirements of the original component while maintaining mechanical and environmental compatibility. Substitutes are grouped by manufacturer and product line status.

Parameter Comparison

Engineering Selection Recommendations

MBN15SD3W01-BC (NKK Switches - Manufacturer Recommended)

This part is designated as the manufacturer-recommended substitute. As an active NKK Switches product, it provides direct lineage from the obsolete MB2011SD3W01-BC. ROHS3 compliance and EAR99 classification align with the original component. However, detailed electrical specifications are not provided in available documentation, requiring verification against application requirements before final selection.

MPA106F and MPE106F (TE Connectivity ALCOSWITCH)

Both TE Connectivity alternatives meet or exceed the electrical requirements of the original component. Current ratings of 6A AC and 4A DC exceed the original 6A AC / 3A DC specification. Voltage ratings of 125V AC and 28V DC provide functional equivalence. Both maintain ROHS3 compliance and EAR99 classification. Electrical life ratings of 50,000 cycles exceed the original 25,000-cycle specification.

Key Differentiation:

MPE106F provides splash-proof ingress protection, offering enhanced environmental sealing compared to the original IP67 specification. MPA106F does not specify ingress protection rating.

Panel cutout diameter for both TE Connectivity alternatives is 6.35mm, compared to the original 6.50mm specification. This 0.15mm difference requires mechanical verification for panel compatibility.

Operating temperature range for both TE Connectivity alternatives is -20°C to 80°C, compared to the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C require alternative evaluation.

Frequently Asked Questions (FAQ)

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

A: Both parts meet the core electrical requirements: SPDT circuit, On-Mom function, 6A at 125V AC, and solder lug termination. However, panel cutout diameter differs by 0.15mm (6.35mm vs. 6.50mm), requiring mechanical verification. Operating temperature range is narrower (-20°C to 80°C vs. -30°C to 85°C). Verify these parameters against your specific application requirements.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications and operating parameters. The primary distinction is ingress protection: MPE106F provides splash-proof protection, while MPA106F does not specify an ingress protection rating. For applications requiring enhanced environmental sealing, MPE106F is the appropriate selection.

Q: Why is MBN15SD3W01-BC listed as the manufacturer-recommended substitute?

A: MBN15SD3W01-BC is designated by NKK Switches as the direct replacement for the obsolete MB2011SD3W01-BC. As a product from the original manufacturer, it maintains design continuity and compliance certifications. Detailed electrical specifications for this part are not provided in available documentation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MB2011SD3W01-BC, MBN15SD3W01-BC, MPA106F, and MPE106F are all ROHS3 compliant and classified as EAR99 for export control purposes.

Q: What is the significance of the 0.15mm panel cutout diameter difference?

A: The original MB2011SD3W01-BC requires a 6.50mm circular panel cutout. TE Connectivity alternatives (MPA106F and MPE106F) require 6.35mm cutouts. This difference may affect mechanical fit in existing panel designs. Verify panel hole dimensions before component selection.

Q: Do the substitute parts have longer electrical life ratings?

A: Yes. MPA106F and MPE106F both specify 50,000 electrical life cycles, compared to 25,000 cycles for the original MB2011SD3W01-BC. This represents a 100% improvement in rated electrical life.
