NKK Switches P2011 Toggle Switch SPST 10A 125V - Equivalent & Substitute Parts

Part Overview

The NKK Switches P2011 is a panel-mount toggle switch with SPST (Single Pole Single Throw) circuit configuration, rated for 10A at 125V AC. This component functions as an on-off switch with a standard round actuator and solder lug termination. The product is classified as obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support where original inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2011 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST to maintain identical electrical function
• Switch Function: Must be On-Off operation
• Voltage Rating: Must support 125V AC minimum
• Current Rating: Must support at least 10A AC (equal or higher ratings are acceptable)
• Mounting Type: Must be Panel Mount for mechanical compatibility
• Actuator Type: Must be Standard Round for form factor consistency
• Termination Style: Must be Solder Lug for connection compatibility
• Panel Cutout Dimensions: Must accommodate the circular 6.35mm diameter opening or be mechanically adaptable
• Bushing Thread: Should be compatible with M6 x 0.75 or equivalent mechanical interface

The Honeywell Sensing and Productivity Solutions part number 11TS115-2 qualifies as a substitute based on matching SPST circuit, on-off function, 125V AC voltage rating, panel mount configuration, standard round actuator, and solder lug termination. The 11TS115-2 provides a higher current rating (20A AC) and operates within an extended temperature range, making it functionally compatible for the P2011 application.

Parameter Comparison

Engineering Selection Recommendations

Both the NKK Switches P2011 and Honeywell Sensing and Productivity Solutions 11TS115-2 are classified as obsolete products. Selection between these components should be based on the following engineering criteria:

NKK Switches P2011 is appropriate when the original panel cutout dimension (6.35mm circular) and M6 x 0.75 bushing thread are fixed mechanical constraints that cannot be modified. The narrower operating temperature range (-10°C to 85°C) is suitable for standard industrial environments.

Honeywell 11TS115-2 is appropriate when panel modifications are feasible to accommodate the larger 12.40mm circular cutout and 15/32-32 bushing thread. The higher current rating (20A versus 10A) provides additional margin for applications with variable load conditions. The extended lower temperature range (-54°C) supports operation in cold environments beyond the P2011 specification. Both components maintain equivalent RoHS compliance status and moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can the Honeywell 11TS115-2 directly replace the NKK P2011 without mechanical modification?

A: No. The panel cutout dimensions differ (6.35mm versus 12.40mm) and the bushing threads are incompatible (M6 x 0.75 versus 15/32-32). Panel drilling and bushing adaptation are required for mechanical installation.

Q: Are the electrical specifications compatible between these two switches?

A: Yes. Both switches are SPST on-off configuration rated for 125V AC. The Honeywell part has a higher current rating (20A versus 10A), which is electrically compatible and provides additional capacity margin.

Q: What is the significance of the different operating temperature ranges?

A: The NKK P2011 operates from -10°C to 85°C, while the Honeywell 11TS115-2 operates from -54°C to 71°C. The Honeywell part supports lower temperatures but has a lower upper temperature limit. Application environment determines which range is appropriate.

Q: Do both switches have equivalent compliance certifications?

A: Both switches are RoHS compliant and have MSL rating of 1 (Unlimited). The P2011 is ROHS3 compliant while the 11TS115-2 is RoHS compliant. Both meet standard regulatory requirements for their respective product generations.

Q: What termination compatibility exists between these switches?

A: Both switches use solder lug termination, making them electrically compatible for PCB or wiring harness connections without adapter requirements.
