Substitute Part Grouping Explanation
Substitution eligibility for the MB2011SS1W01/CUL is determined by the following critical parameters:
- Circuit Configuration: Must be SPDT to maintain electrical functionality
- Switch Function: Must be On-Mom (momentary operation)
- Current Rating (AC): Minimum 6A at 125V AC
- Current Rating (DC): Minimum 3A at 30V DC
- Mounting Type: Panel Mount, Rear installation required
- Termination Style: Solder Lug connections
- Panel Cutout Compatibility: Circular mounting hole within acceptable tolerance range
The substitute parts identified—MPA106F, MPE106F, and MB2011SS1W01/CUL-N986—meet the core electrical and mechanical requirements. MPA106F and MPE106F are manufactured by TE Connectivity ALCOSWITCH Switches and maintain SPDT momentary operation with equivalent AC voltage and current ratings. MPE106F provides enhanced ingress protection (Splash Proof). MB2011SS1W01/CUL-N986 is the NKK Switches variant with active product status.

Engineering Selection Recommendations
Primary Recommendation: MB2011SS1W01/CUL-N986
This part is the direct NKK Switches equivalent with active product status, ensuring long-term availability and supply chain continuity. Selection of this variant eliminates manufacturer transition concerns and maintains design consistency within the NKK Switches MB2000 series.
Secondary Recommendations: MPA106F and MPE106F
Both TE Connectivity ALCOSWITCH parts satisfy the core electrical requirements with equivalent AC ratings and superior DC current capacity (4A versus 3A). These parts feature extended electrical life (50,000 cycles versus 25,000 cycles) and maintain ROHS3 compliance. MPA106F provides standard functionality, while MPE106F adds Splash Proof ingress protection for applications requiring enhanced environmental resistance.
Compliance Considerations
All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. DC voltage ratings of 28V on TE Connectivity parts are within acceptable tolerance for the original 30V specification in typical industrial applications.
Panel Cutout Compatibility
The 0.15mm difference in panel cutout diameter (6.50mm original versus 6.35mm substitutes) requires verification of mechanical fit within the target application. Standard panel mount tolerances typically accommodate this variance, but physical validation is necessary for critical installations.
Frequently Asked Questions (FAQ)
Q: Can MPA106F or MPE106F directly replace MB2011SS1W01/CUL without modification?
A: Both parts maintain identical SPDT momentary operation, AC voltage and current ratings, and solder lug termination. The 0.15mm panel cutout diameter difference requires mechanical fit verification. DC voltage rating of 28V is functionally equivalent to the original 30V specification in standard applications.
Q: What is the difference between MPA106F and MPE106F?
A: Both parts share identical electrical specifications and current ratings. MPE106F includes Splash Proof ingress protection, making it suitable for applications with moisture or environmental exposure. MPA106F is the standard variant without enhanced protection.
Q: Why is MB2011SS1W01/CUL-N986 recommended as the primary substitute?
A: This part is manufactured by NKK Switches, the original manufacturer, and maintains active product status. It eliminates cross-manufacturer qualification requirements and ensures design continuity within the MB2000 series platform.
Q: Are there electrical performance differences between the original and substitute parts?
A: TE Connectivity ALCOSWITCH substitutes (MPA106F, MPE106F) provide superior electrical life (50,000 cycles versus 25,000 cycles) and higher DC current capacity (4A versus 3A). AC ratings and voltage specifications remain equivalent.
Q: What packaging format is available for these substitute parts?
A: All substitute parts are supplied in Bulk packaging, consistent with the original MB2011SS1W01/CUL specification.
Q: Are all substitute parts RoHS compliant?
A: Yes. MB2011SS1W01/CUL-N986, MPA106F, and MPE106F are all ROHS3 compliant, meeting current environmental and regulatory requirements.
