P2022YZ-JC Rocker Switch DPDT Equivalent & Substitute Parts

Part Overview

The P2022YZ-JC is a panel-mount rocker switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) switch with a 10A AC rating at 125V. This component features a concave red actuator with quick-connect 0.187" termination and is designed for rectangular panel cutouts of 28.50mm x 16.00mm. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2022YZ-JC is determined by strict equivalence across the following critical parameters:

Circuit configuration must remain DPDT with On-On switching function. Current and voltage ratings must meet or exceed the original specification: minimum 10A AC at 125V. Mounting type must be panel mount with flange configuration. Termination style must be quick-connect 0.187" (4.7mm) to ensure direct compatibility with existing wiring harnesses. Panel cutout dimensions must accommodate the original rectangular opening or be compatible within standard tolerance ranges. Actuator type and color should match for functional and visual consistency. Operating temperature range must encompass the original -10°C ~ 85°C specification. Electrical life rating must be equivalent to or greater than 25,000 cycles. RoHS3 compliance is required for regulatory alignment.

The substitute part 9221J3Z4QD3 (C&K) meets these criteria with the following considerations: it maintains DPDT On-On configuration, supports 10A at 125V AC (with additional 30V DC capability), uses identical quick-connect termination, features matching red concave actuator, and maintains 25,000 cycle electrical life. Panel cutout dimensions differ slightly (27.81mm x 16.46mm versus 28.50mm x 16.00mm), requiring verification of mechanical fit in the target application. Operating temperature range is extended (-30°C ~ 85°C). RoHS3 compliance is maintained.

Parameter Comparison

Engineering Selection Recommendations

The 9221J3Z4QD3 (C&K) is the identified equivalent substitute for the obsolete P2022YZ-JC. Selection of this substitute is supported by functional equivalence across all critical electrical parameters: identical DPDT On-On configuration, matching 10A AC 125V ratings, and equivalent 25,000 cycle electrical life.

The substitute maintains active product status, ensuring ongoing availability and supply chain continuity. Both components hold RoHS3 compliance, satisfying regulatory requirements. The C&K part extends operating temperature capability to -30°C, providing enhanced performance margin in cold environments compared to the original -10°C lower limit.

Mechanical compatibility requires verification of panel cutout dimensions. The substitute dimensions (27.81mm x 16.46mm) differ from the original (28.50mm x 16.00mm). Panel openings designed for the P2022YZ-JC may require modification or use of adapter hardware to accommodate the C&K substitute. Quick-connect termination compatibility is confirmed, eliminating rewiring requirements.

Approval certifications differ: the original holds CSA, UL, and VDE approvals, while the substitute holds cULus certification. Application-specific regulatory requirements must be evaluated to confirm certification adequacy for the target market and end-use environment.

Frequently Asked Questions (FAQ)

Q: Can the 9221J3Z4QD3 be used as a direct drop-in replacement for the P2022YZ-JC?

A: Electrical compatibility is confirmed. Mechanical compatibility requires panel cutout dimension verification. The substitute dimensions (27.81mm x 16.46mm) differ from the original (28.50mm x 16.00mm). Panel modifications may be necessary. Quick-connect termination is identical, eliminating wiring changes.

Q: What are the key differences between these two switches?

A: The primary differences are product status (obsolete versus active), panel cutout dimensions, operating temperature range extension, and approval certifications. Electrical specifications and switching function are equivalent. The C&K substitute adds DC voltage capability (30V) not specified in the original.

Q: Are there any compliance concerns when substituting the P2022YZ-JC with the 9221J3Z4QD3?

A: RoHS3 compliance is maintained by both components. Approval certifications differ: the original holds CSA, UL, and VDE approvals, while the substitute holds cULus certification. Applications requiring specific regional certifications must confirm that cULus approval meets regulatory requirements for the target market.

Q: Does the substitute support the same current and voltage ratings?

A: Yes. Both switches are rated for 10A AC at 125V. The substitute additionally supports 30V DC operation, which is not specified for the original component.

Q: What is the impact of the panel cutout dimension difference?

A: The substitute requires a panel opening of 27.81mm x 16.46mm compared to the original 28.50mm x 16.00mm. Existing panel cutouts designed for the P2022YZ-JC may require enlargement or modification to accommodate the C&K part. Mechanical fit must be verified before installation.

Q: Are the electrical life ratings equivalent?

A: Yes. Both components are rated for 25,000 electrical cycles, ensuring equivalent operational durability under specified switching conditions.
