B22KV-AC Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The B22KV-AC is an NKK Switches toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 28V AC/DC. This through-hole, right-angle vertical mounted switch features a snap-on paddle actuator and is designed for applications requiring reliable switching in industrial and commercial environments. The part is currently active in production with 785 units in stock. Equivalent and substitute parts are identified for applications where alternative actuator designs, mounting orientations, or extended electrical life cycles are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B22KV-AC is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT
• Current Rating: Must support 0.4VA (AC/DC)
• Voltage Rating: Must support minimum 28V AC and 28V DC
• Termination Style: Must be PC Pin
• Mounting Type: Through hole configuration required
• RoHS Compliance: Must meet ROHS3 standard

The identified substitute parts meet these core electrical and mechanical requirements while differing in secondary characteristics such as actuator type, actuator length, switch function variant, and electrical life cycle ratings.

Engineering Selection Recommendations

B22KV-AC (Primary Part): Select this part for applications requiring a snap-on paddle actuator with right-angle vertical mounting. Suitable for 28V AC/DC systems with standard duty cycles up to 50,000 operations. ROHS3 compliant and actively produced.

G23AP (NKK Substitute): This part offers identical voltage and current ratings with extended electrical life of 100,000 cycles. The standard round actuator and reduced actuator length (3.80mm) provide a more compact profile. Mounting type is through-hole without specified right-angle orientation. Select when extended operational life and compact actuator design are prioritized. ROHS3 compliant.

T201MH9AVBE (C&K Substitute): This part maintains right-angle vertical mounting and On-On switch function identical to the B22KV-AC. Voltage rating is reduced to 20V AC/DC, limiting application to lower voltage systems. Electrical life is 60,000 cycles. ROHS3 compliant with REACH affected status. Select only when 20V operation is acceptable and right-angle vertical mounting is required.

All substitute parts maintain ROHS3 compliance and PC Pin termination required for direct circuit board integration.

Frequently Asked Questions (FAQ)

Q: Can G23AP replace B22KV-AC in a 28V application? A: Yes. G23AP supports 28V AC/DC identical to B22KV-AC. Primary differences are actuator type (standard round vs. snap-on paddle), actuator length (3.80mm vs. 9.40mm), and mounting specification (through-hole vs. right-angle vertical). Verify panel cutout and actuator engagement requirements before substitution.

Q: What is the voltage limitation of T201MH9AVBE? A: T201MH9AVBE is rated for 20V AC/DC maximum, compared to 28V for B22KV-AC. This part is not suitable for systems operating above 20V. Use only in applications where system voltage does not exceed 20V AC/DC.

Q: Which substitute offers the longest operational life? A: G23AP provides 100,000 electrical cycles, compared to 50,000 cycles for B22KV-AC and 60,000 cycles for T201MH9AVBE. Select G23AP for high-cycle applications requiring extended switch life.

Q: Are all parts ROHS3 compliant? A: Yes. B22KV-AC, G23AP, and T201MH9AVBE are all ROHS3 compliant. T201MH9AVBE carries REACH affected status; verify regulatory requirements for your application region.

Q: What is the difference between On-On and On-Off-On switch functions? A: B22KV-AC and T201MH9AVBE feature On-On function, where both switch positions are active. G23AP features On-Off-On function, where the center position is off and both end positions are active. Select based on circuit control requirements.

Q: Can these parts be used interchangeably in PCB assembly? A: All three parts use PC Pin termination and through-hole mounting, enabling PCB compatibility. However, verify actuator length, mounting orientation (right-angle vs. standard), and panel cutout dimensions for your specific mechanical design before substitution.
