LP2S-27S-209-Z Equivalent & Substitute Parts

Part Overview

The LP2S-27S-209-Z is a pushbutton switch manufactured by Nidec Components Corporation, configured as a DPDT (Double Pole Double Throw) illuminated panel mount switch with snap-in mounting. This component is rated for 3A at 125V AC and 30V DC, featuring a red LED illumination at 2VDC nominal. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

The LB26SKW01-5C-JC from NKK Switches qualifies as a functional equivalent based on the following critical parameters:

• Circuit Configuration: Both parts are DPDT with On-On switching function
• Electrical Ratings: Both rated for 3A at 125V AC and 30V DC
• Mechanical Interface: Both feature panel mount snap-in mounting with identical 16.20mm x 16.20mm square panel cutout dimensions
• Illumination: Both incorporate red LED illumination
• Actuator Design: Both use square button actuators with no marking
• Compliance: Both are ROHS3 compliant with MSL 1 (Unlimited) rating

Substitution is valid where the electrical load, panel geometry, and illumination requirements match the original specification.

Parameter Comparison

Engineering Selection Recommendations

The LB26SKW01-5C-JC is an active production equivalent suitable for replacing the obsolete LP2S-27S-209-Z in applications requiring DPDT illuminated pushbutton switches with 3A/125V AC ratings and panel mount snap-in installation.

Both components meet ROHS3 compliance and carry unlimited moisture sensitivity ratings, ensuring regulatory and environmental compatibility. The NKK substitute offers extended electrical life (100,000 cycles versus 30,000 cycles) and broader operating temperature range (-25°C to 50°C versus -15°C to 60°C), providing enhanced reliability in demanding environments.

Termination style differs between the two parts: the original uses solder lugs while the substitute provides both solder and quick connect 0.110" (2.8mm) options. This difference requires evaluation of the existing PCB or panel wiring configuration. Illumination voltage is nominally equivalent (2VDC versus 1.9VDC), with both red LED implementations suitable for standard indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the LB26SKW01-5C-JC directly replace the LP2S-27S-209-Z without circuit modification?

A: Direct replacement is possible where panel cutout dimensions and electrical load requirements match. The identical 16.20mm x 16.20mm square panel cutout and matching 3A/125V AC ratings enable mechanical and electrical compatibility. Termination style differences (solder lug versus quick connect) require assessment of the existing connection method.

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

A: Primary differences include product status (obsolete versus active), termination options (solder lug only versus solder and quick connect), electrical life rating (30,000 versus 100,000 cycles), and operating temperature range (-15°C to 60°C versus -25°C to 50°C). Illumination voltage is nominally equivalent at approximately 2VDC.

Q: Are both switches ROHS3 compliant?

A: Yes, both the LP2S-27S-209-Z and LB26SKW01-5C-JC are ROHS3 compliant with MSL 1 (Unlimited) ratings, meeting current environmental and regulatory requirements.

Q: What is the panel cutout requirement for installation?

A: Both switches require an identical square panel cutout of 16.20mm x 16.20mm, enabling direct mechanical substitution in existing panel designs.

Q: Does the illumination voltage difference affect circuit design?

A: The nominal illumination voltage difference (2VDC versus 1.9VDC) is within typical LED operating tolerance and does not require circuit redesign for standard indicator applications. Verify LED current limiting resistor values remain appropriate for the substitute component.
