NKK Switches P2023 Toggle Switch DPDT 10A 125V - Equivalent & Substitute Parts

Part Overview

The NKK Switches P2023 is a panel-mount toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 10A at 125V AC. This component features a standard round actuator with white cap, solder lug termination, and a circular 6.35mm panel cutout. The P2023 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing maintenance, repair, and new design applications where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2023 is determined by strict equivalence across the following critical parameters:

Circuit & Electrical Requirements:

• DPDT circuit configuration (mandatory)
• On-Off-On switch function (mandatory)
• Current rating must meet or exceed 10A AC (mandatory)
• Voltage rating must support 125V AC minimum (mandatory)

Mechanical & Installation Requirements:

• Panel mount configuration (mandatory)
• Solder lug termination style (mandatory)
• Standard round actuator with cap (mandatory)
• Panel cutout diameter compatibility (6.35mm reference)
• Bushing thread compatibility (M6 x 0.75 reference)

Environmental & Compliance Requirements:

• Operating temperature range must encompass -10°C to 85°C minimum
• RoHS3 compliance required
• Electrical life minimum 25,000 cycles

The M2023SS1W01-CB from NKK Switches meets the circuit, function, mounting, termination, and actuator requirements. However, its current rating of 6A AC is below the P2023 specification of 10A AC, and its panel cutout diameter (6.50mm) and bushing thread (1/4-40) differ from the original. This part is listed as a substitute option where current requirements do not exceed 6A AC and mechanical dimensions can be accommodated.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Load): The M2023SS1W01-CB is suitable only where the application current requirement does not exceed 6A AC. Both parts are ROHS3 compliant and share identical electrical life ratings. The M2023SS1W01-CB provides an extended operating temperature range (-30°C to 85°C versus -10°C to 85°C), which may be advantageous in cold environments.

For Applications Requiring 10A AC Rating: No substitute part meeting the full 10A AC specification is provided in the available data. Applications requiring the original 10A AC rating must source the P2023 from remaining inventory or identify alternative DPDT toggle switches from other manufacturers with equivalent electrical specifications.

Mechanical Compatibility Considerations: Panel cutout diameter and bushing thread differences between P2023 (6.35mm, M6 x 0.75) and M2023SS1W01-CB (6.50mm, 1/4-40) require mechanical adaptation or panel redesign. These dimensional differences must be evaluated against installation constraints.

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and replacements in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the M2023SS1W01-CB directly replace the P2023 in all applications?

A: No. The M2023SS1W01-CB has a lower current rating (6A AC versus 10A AC). It is suitable only for applications where the actual circuit current does not exceed 6A AC. Panel cutout and bushing thread dimensions also differ, requiring mechanical adaptation.

Q: What is the primary limitation of the M2023SS1W01-CB as a substitute?

A: Current rating. The M2023SS1W01-CB is rated for 6A AC, which is 40% below the P2023 specification of 10A AC. Exceeding this rating will compromise switch reliability and safety.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the P2023 and M2023SS1W01-CB are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic components in most jurisdictions.

Q: What mechanical modifications are required to use the M2023SS1W01-CB in place of the P2023?

A: Panel cutout diameter must accommodate 6.50mm (versus 6.35mm), and the bushing thread is 1/4-40 (versus M6 x 0.75). Panel redesign or adapter hardware may be necessary depending on installation constraints.

Q: Does the M2023SS1W01-CB offer any advantages over the P2023?

A: The M2023SS1W01-CB provides an extended operating temperature range (-30°C to 85°C versus -10°C to 85°C), making it suitable for applications in colder environments. Both parts share identical electrical life ratings and circuit configuration.

Q: What should be done if an application requires the full 10A AC rating of the P2023?

A: Consult remaining P2023 inventory or evaluate alternative DPDT toggle switches from NKK Switches or other manufacturers that meet the 10A AC specification and panel-mount requirements.
