P2011N-DA Equivalent & Substitute Parts

Part Overview

The P2011N-DA is a rocker switch manufactured by NKK Switches, classified as SPST (Single Pole Single Throw) with On-Off functionality. This panel-mount, flange-style switch is rated for 10A AC at 125V and features a concave black actuator with solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2011N-DA is determined by the following core parameters:

• Circuit Configuration: Must be SPST to maintain identical electrical topology
• Switch Function: Must be On-Off to preserve operational behavior
• Mounting Type: Must be Panel Mount, Flange to ensure mechanical compatibility
• Actuator Type: Must be Concave (Standard V) for consistent user interface
• Termination Style: Must be Solder Lug for circuit board integration compatibility
• Voltage Rating - AC: Must support minimum 125V AC operation
• Current Rating: Must support minimum 10A AC operation
• Mechanical and Electrical Life: Must meet or exceed specified cycle ratings

The SW3001A qualifies as a substitute based on these parameters. While it offers enhanced current rating (15A AC/DC) and additional DC voltage capability (30V), it maintains all core compatibility requirements for direct substitution in applications designed for the P2011N-DA.

Parameter Comparison

Engineering Selection Recommendations

The SW3001A is a qualified substitute for the P2011N-DA based on matching core electrical and mechanical parameters. Both components share identical SPST circuit configuration, On-Off functionality, 125V AC voltage rating, 50,000-cycle mechanical life, and 25,000-cycle electrical life. Both are ROHS3 compliant and manufactured by NKK Switches with identical mounting and termination specifications.

Selection of SW3001A over P2011N-DA is justified by product availability: P2011N-DA is obsolete, while SW3001A maintains active production status. The SW3001A provides enhanced current capacity (15A AC/DC versus 10A AC), which offers design margin for applications within the original 10A specification.

Two considerations apply to this substitution:

1. Operating temperature range: SW3001A operates to 70°C maximum, compared to P2011N-DA at 85°C. Applications requiring operation above 70°C require alternative solutions.

2. Approval certifications: P2011N-DA carries VDE approval in addition to CSA and UL certifications. SW3001A holds CSA and UL approval only. Applications requiring VDE certification must verify compliance requirements independently.

Frequently Asked Questions (FAQ)

Q: Can SW3001A be used as a direct replacement for P2011N-DA in existing designs?

A: Yes, for applications operating within -10°C to 70°C and not exceeding 10A AC at 125V. The SW3001A maintains identical circuit topology, mounting configuration, and termination style. Verify that VDE certification is not a design requirement.

Q: What is the primary difference between these two switches?

A: The SW3001A offers higher current capacity (15A AC/DC) and dual voltage support (125V AC and 30V DC), while the P2011N-DA is limited to 10A AC at 125V. The SW3001A also operates to a lower maximum temperature (70°C versus 85°C) and lacks VDE certification.

Q: Are the panel cutout dimensions identical?

A: The P2011N-DA specifies rectangular panel cutout dimensions of 17.80mm x 10.10mm. Panel cutout dimensions for SW3001A are not provided in available specifications. Verify mechanical fit before implementation.

Q: What is the actuator color difference?

A: P2011N-DA features a black concave actuator, while SW3001A features a white concave actuator. Both are unmarked. Visual identification and user interface consistency should be evaluated for your application.

Q: Are both switches suitable for DC applications?

A: P2011N-DA is rated for AC operation only (10A AC at 125V). SW3001A supports both AC and DC operation (15A AC/DC at 125V AC, 30V DC). If DC switching is required, SW3001A is the appropriate selection.

Q: What certifications apply to each switch?

A: P2011N-DA holds CSA, UL, and VDE approvals. SW3001A holds CSA and UL approvals. Applications requiring VDE certification must confirm compliance independently or identify alternative components.
