Substitute Part Grouping Explanation
Substitution for the P2011BP/U is determined by strict equivalence across the following critical parameters:
- Circuit configuration (SPST)
- Current rating (10A AC minimum)
- Voltage rating (125V AC minimum)
- Mounting type (Panel Mount)
- Actuator type and length (Standard Round, 17.50mm)
- Termination style (PC Pin)
- Panel cutout dimensions (Circular 12.50mm Dia)
- Bushing thread specification (M12 x 1)
- Operating temperature range (-10°C to 85°C minimum)
The substitute part P2011BP meets all these criteria and is therefore classified as a direct equivalent. The part M2011B2B1W03 is identified as an additional substitute option within the same product family.

Engineering Selection Recommendations
The P2011BP serves as the primary direct substitute for the P2011BP/U. Both components are classified as obsolete products from NKK Switches and share identical electrical and mechanical specifications. The P2011BP offers ROHS3 compliance, providing enhanced environmental regulatory alignment compared to the main part number.
For applications requiring component sourcing, the P2011BP is the preferred selection due to documented availability (835 pcs in stock versus 973 pcs for the original part number) and equivalent functional performance across all critical parameters.
The M2011B2B1W03 is identified as an additional substitute within the NKK Switches product family and should be evaluated for compatibility based on specific application requirements and mechanical integration constraints.
Frequently Asked Questions (FAQ)
Q: Can P2011BP directly replace P2011BP/U in existing installations?
A: Yes. Both components share identical electrical ratings (10A, 125V AC), circuit configuration (SPST), mechanical dimensions (M12 x 1 bushing, 12.50mm panel cutout), and actuator specifications (Standard Round, 17.50mm length). Panel mounting and PC pin termination are identical.
Q: What is the significance of the ROHS3 compliance on the P2011BP?
A: ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive 3, reflecting current environmental and material composition standards. This does not affect electrical or mechanical compatibility but may be relevant for regulatory compliance in specific markets or applications.
Q: Are there mechanical integration differences between the substitute parts?
A: No. The P2011BP maintains identical panel cutout dimensions (Circular 12.50mm Dia), bushing thread specification (M12 x 1), and actuator geometry (Standard Round, 17.50mm). Direct mechanical substitution is supported without modification to panel mounting hardware or cutouts.
Q: What is the basis for substitution eligibility?
A: Substitution is based on equivalence across circuit configuration, current and voltage ratings, mounting type, actuator specifications, termination style, panel dimensions, and operating temperature range. All identified substitutes meet these criteria.
Q: Does the electrical life rating (25,000 cycles) apply to all substitute parts?
A: Yes. The electrical life specification of 25,000 cycles is consistent across the main part and identified substitutes, indicating equivalent operational durability under specified conditions.
