NKK Switches B23KP Toggle Switch DPDT Equivalent & Substitute Parts
Part Overview
The NKK Switches B23KP is an active-status toggle switch featuring DPDT (Double Pole Double Throw) circuitry with On-Off-On switching function. This through-hole mounted component is rated for 0.4VA at 28V AC/DC operation across a temperature range of -30°C to 85°C. The B23KP serves applications requiring reliable electromechanical switching with sealed terminals and 50,000 electrical life cycles. Substitute parts are identified when equivalent electrical ratings, circuit configurations, and mechanical mounting specifications align with application requirements.

Substitute Part Grouping Explanation
Substitute parts for the B23KP are identified based on the following critical parameters that determine functional equivalence:
Circuit Configuration: DPDT topology required for identical switching capability Switch Function: On-Off-On operation mandatory Current Rating: 0.4VA AC/DC minimum requirement Mounting Type: Through Hole configuration for PCB compatibility Termination Style: PC Pin for direct board insertion Operating Temperature: -30°C to 85°C range support RoHS Compliance: ROHS3 status for regulatory alignment
The E-Switch 200MDP3T2B2M2RE qualifies as a substitute based on matching circuit, function, current rating, mounting, termination, temperature range, and RoHS compliance. Voltage rating differences (20V substitute vs. 28V main part) represent a derating condition acceptable for applications operating below the substitute's maximum voltage specification.

Engineering Selection Recommendations
Both the NKK Switches B23KP and E-Switch 200MDP3T2B2M2RE maintain active product status with ROHS3 compliance and REACH unaffected designation, supporting current regulatory requirements. Selection between these components depends on application voltage requirements: the B23KP supports 28V operation, while the 200MDP3T2B2M2RE operates at 20V maximum. The B23KP provides extended electrical life at 50,000 cycles compared to the substitute's 30,000 cycles. Both components feature epoxy sealed terminals and identical operating temperature ranges, supporting equivalent environmental performance in -30°C to 85°C applications.
Frequently Asked Questions (FAQ)
Q: Can the E-Switch 200MDP3T2B2M2RE replace the NKK Switches B23KP in all applications?
A: Substitution is valid only for applications operating at 20V or below. The 200MDP3T2B2M2RE's 20V maximum rating is lower than the B23KP's 28V rating. Applications requiring 28V operation must use the B23KP or equivalent 28V-rated alternatives.
Q: What is the significance of the 50,000 vs. 30,000 electrical life difference?
A: The B23KP provides 50,000 switching cycles before rated performance degradation, while the 200MDP3T2B2M2RE provides 30,000 cycles. Applications with high switching frequency or extended service life requirements should prioritize the higher cycle rating.
Q: Are both parts suitable for the same PCB mounting configuration?
A: Yes. Both components feature through-hole mounting with PC pin termination, supporting identical PCB footprints and assembly processes.
Q: Do both parts meet current regulatory compliance requirements?
A: Yes. Both the B23KP and 200MDP3T2B2M2RE are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.
Q: What is the actuator length difference between these parts?
A: The B23KP features a 5.00mm lever actuator, while the 200MDP3T2B2M2RE has a 5.33mm standard round actuator. This dimensional difference may affect panel cutout compatibility and operator feel but does not impact electrical function.
