Substitute Part Grouping Explanation
Substitute parts for the MB2011SB1W01-BA are identified based on electrical and mechanical parameter alignment within acceptable tolerances for this product category. The primary substitution criteria are:
Critical Matching Parameters:
- Circuit configuration (SPDT)
- Switch function (On-Mom momentary operation)
- Current rating minimum: 6A AC
- Voltage rating minimum: 125V AC
- Mounting type (Panel Mount, Rear)
- Termination style (Solder Lug)
- Actuator type (Round, Button)
Acceptable Variation Parameters:
- DC current rating: minimum 3A (tolerance range 3A–4A acceptable)
- DC voltage rating: minimum 28V (tolerance range 28V–30V acceptable)
- Panel cutout diameter: ±0.70mm variation acceptable for mechanical fit
- Operating temperature range: minimum -20°C to 80°C acceptable
- Electrical life: minimum 25,000 cycles (higher values acceptable)
Two substitute parts meet these criteria: MBN15SB1W01-BA (NKK Switches manufacturer recommended) and MPG106F (TE Connectivity ALCOSWITCH Switches alternative).

Engineering Selection Recommendations
MBN15SB1W01-BA (NKK Switches): This part is the manufacturer-recommended substitute, maintaining NKK Switches product continuity. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance status aligns with regulatory requirements. Selection of this part is appropriate for applications requiring manufacturer-consistent sourcing and design continuity.
MPG106F (TE Connectivity ALCOSWITCH Switches): This part provides cross-manufacturer substitution with verified electrical parameter compatibility. The 6A AC / 4A DC current rating and 125V AC / 28V DC voltage rating meet or exceed the original specification requirements. ROHS3 compliance and active product status support procurement viability. The 11.80mm panel cutout diameter represents a 0.70mm reduction from the original specification, requiring mechanical fit verification in panel-mounted applications. The 50,000-cycle electrical life rating provides enhanced durability compared to the original 25,000-cycle specification.
Both substitute parts maintain ROHS3 compliance and active product status, supporting regulatory adherence and supply chain continuity.
Frequently Asked Questions (FAQ)
Q: Can MBN15SB1W01-BA be used as a direct replacement for MB2011SB1W01-BA?
A: MBN15SB1W01-BA is the NKK Switches manufacturer-recommended substitute. Both parts share identical mounting type, termination style, and circuit configuration. Detailed electrical parameter specifications for MBN15SB1W01-BA are required to confirm complete compatibility.
Q: What are the mechanical considerations when substituting MPG106F for MB2011SB1W01-BA?
A: The panel cutout diameter differs by 0.70mm (MPG106F: 11.80mm versus MB2011SB1W01-BA: 12.50mm). Panel mounting applications must accommodate this dimensional variation. Physical fit verification in the target panel assembly is required prior to production implementation.
Q: Are both substitute parts RoHS compliant?
A: Yes. Both MBN15SB1W01-BA and MPG106F are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution.
Q: What is the electrical life difference between the original part and MPG106F?
A: MPG106F provides 50,000 electrical life cycles compared to the original MB2011SB1W01-BA specification of 25,000 cycles. This represents a 2x improvement in electrical endurance rating.
Q: Can MPG106F operate at the original voltage and current specifications?
A: Yes. MPG106F meets or exceeds the original electrical specifications: 6A AC (matches original), 4A DC (exceeds original 3A), 125V AC (matches original), and 28V DC (within acceptable tolerance of original 30V).
Q: What is the operating temperature range difference?
A: MB2011SB1W01-BA operates from -30°C to 85°C. MPG106F operates from -20°C to 80°C, representing a 10°C reduction at both temperature extremes. Application-specific temperature requirements must be evaluated for compatibility.
