MB2011SD1W01-BA Equivalent & Substitute Parts
Part Overview
The MB2011SD1W01-BA is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating and 125V AC / 30V DC voltage rating. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The switch employs panel mount rear termination with solder lug connections and epoxy sealed terminals for environmental protection.

Substitute Part Grouping Explanation
Substitution eligibility for the MB2011SD1W01-BA is determined by the following critical parameters:
Mandatory Matching Criteria:
- Circuit configuration: SPDT
- Switch function: On-Mom
- AC current rating: 6A minimum
- AC voltage rating: 125V minimum
- Mounting type: Panel Mount, Rear
- Termination style: Solder Lug
Allowable Variations:
- DC current rating: Substitute may exceed 3A (higher ratings are acceptable)
- DC voltage rating: Substitute may exceed 30V (higher ratings are acceptable)
- Panel cutout diameter: Substitute at 6.35mm is compatible with 6.50mm requirement (within mechanical tolerance)
- Operating temperature range: Substitute range may be narrower than -30°C to 85°C
- Electrical life: Substitute may exceed 25,000 cycles (higher ratings are acceptable)
- Mechanical life: Data not required for substitutes
The substitute parts MPA106F and MPE106F meet all mandatory criteria and fall within allowable variation parameters.

Engineering Selection Recommendations
Both MPA106F and MPE106F are active production parts from TE Connectivity ALCOSWITCH Switches and satisfy all electrical and mechanical substitution requirements for the obsolete MB2011SD1W01-BA.
MPA106F Selection Basis:
- Meets all mandatory electrical parameters (6A AC, 125V AC, SPDT, On-Mom)
- Exceeds DC current capability (4A vs. 3A required)
- ROHS3 compliant
- Active product status ensures long-term availability
- Operating temperature range of -20°C to 80°C is narrower than original but suitable for most industrial applications
MPE106F Selection Basis:
- Meets all mandatory electrical parameters (6A AC, 125V AC, SPDT, On-Mom)
- Exceeds DC current capability (4A vs. 3A required)
- ROHS3 compliant
- REACH Affected status indicates full regulatory compliance documentation
- Splash Proof ingress protection provides enhanced environmental resistance
- Active product status ensures long-term availability
- Operating temperature range of -20°C to 80°C is narrower than original but suitable for most industrial applications
Selection between MPA106F and MPE106F depends on environmental exposure requirements. MPE106F is recommended for applications requiring splash protection.
Frequently Asked Questions (FAQ)
Q: Can MPA106F or MPE106F directly replace MB2011SD1W01-BA in existing designs?
A: Yes. Both substitute parts match the mandatory electrical specifications (SPDT circuit, 6A AC, 125V AC, On-Mom function) and mechanical interface (panel mount rear, solder lug termination). Panel cutout diameter difference (6.35mm vs. 6.50mm) is within standard mechanical tolerance for circular panel cutouts.
Q: What is the difference between MPA106F and MPE106F?
A: Both parts share identical electrical ratings and circuit configuration. MPE106F provides Splash Proof ingress protection, while MPA106F does not specify ingress protection. MPE106F carries REACH Affected status, indicating full regulatory documentation. Selection depends on environmental exposure requirements.
Q: Are there any temperature range limitations when substituting?
A: Both substitute parts operate within -20°C to 80°C, which is narrower than the original MB2011SD1W01-BA range of -30°C to 85°C. Applications requiring operation below -20°C or above 80°C require design review.
Q: Do the substitute parts meet RoHS compliance?
A: Yes. Both MPA106F and MPE106F are ROHS3 compliant, matching the compliance status of the original MB2011SD1W01-BA.
Q: What is the electrical life advantage of the substitute parts?
A: MPA106F and MPE106F both provide 50,000 electrical cycles, compared to 25,000 cycles for the original part. This represents a 2x improvement in electrical life rating.
Q: Are packaging considerations different between these parts?
A: The original MB2011SD1W01-BA is packaged individually. Both MPA106F and MPE106F are supplied in bulk packaging. Procurement quantities and handling procedures may require adjustment.
