NKK Switches P2011E Toggle Switch SPST Equivalent & Substitute Parts

Part Overview

The NKK Switches P2011E is a panel-mount toggle switch with SPST (Single Pole Single Throw) circuit configuration, rated for 10A at 125V AC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and new design applications where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2011E is determined by the following critical parameters:

• Circuit Configuration: Must be SPST (Single Pole Single Throw)
• Mounting Type: Must be Panel Mount with compatible mechanical interface
• Actuator Geometry: Flatted actuator type with 11.40mm length
• Termination: Solder Lug termination required
• Electrical Performance: Current and voltage ratings must meet or exceed application requirements
• Panel Interface: Panel cutout diameter and bushing thread must accommodate mechanical installation

The substitute part M2011ES1W01 shares the same circuit topology, mounting configuration, actuator design, and termination style. However, electrical ratings differ: the substitute is rated for 6A AC (4A DC) at 125V AC, representing a reduced current capacity compared to the original 10A rating.

Parameter Comparison

Engineering Selection Recommendations

The M2011ES1W01 is functionally equivalent to the P2011E for applications requiring SPST panel-mount toggle switch operation at 125V AC. Both components are ROHS3 compliant and share identical electrical life specifications.

Critical Consideration: The substitute part has a reduced AC current rating of 6A compared to the original 10A specification. Selection of M2011ES1W01 is appropriate only for applications where the circuit load does not exceed 6A AC at 125V. For applications requiring the full 10A capacity of the original P2011E, this substitute is not suitable.

Mechanical Interface: The panel cutout diameter increases from 6.35mm to 6.50mm, and the bushing thread changes from M6 x 0.75 to 1/4-40. Panel modifications may be required for installation.

Temperature Performance: The substitute part extends the lower operating temperature limit to -30°C, providing improved performance in cold environments compared to the -10°C minimum of the original.

Frequently Asked Questions (FAQ)

Q: Can M2011ES1W01 directly replace P2011E in all applications?

A: No. The substitute part is rated for 6A AC maximum, while the original is rated for 10A AC. Substitution is valid only for applications where circuit current does not exceed 6A AC at 125V.

Q: What are the mechanical compatibility issues between these parts?

A: Panel cutout diameter differs (6.35mm vs. 6.50mm) and bushing threads are different (M6 x 0.75 vs. 1/4-40). Panel modifications or adapter hardware may be necessary for installation.

Q: Are both parts RoHS compliant?

A: Yes. Both P2011E and M2011ES1W01 are ROHS3 compliant.

Q: Do both parts have the same electrical life rating?

A: Yes. Both components are rated for 25,000 electrical cycles.

Q: What is the temperature performance difference?

A: M2011ES1W01 operates from -30°C to 85°C, while P2011E operates from -10°C to 85°C. The substitute provides a 20°C lower temperature limit.

Q: Are there DC voltage or current ratings for these parts?

A: The substitute M2011ES1W01 is rated for 4A DC at 30V DC. The original P2011E specifications do not include DC ratings in the provided data.
