LP2S-26S-W-Z Equivalent & Substitute Parts

Part Overview

The LP2S-26S-W-Z is a pushbutton switch manufactured by Nidec Components Corporation, featuring DPDT (Double Pole Double Throw) circuitry with On-Momentary switch function. This component is rated for 3A at 125V AC and 30V DC, with a square white button actuator and solder lug termination for panel mount, snap-in installation. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and new design applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP2S-26S-W-Z is determined by strict alignment of the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained for functional equivalence
• Switch Function: On-Momentary operation required
• Mounting Interface: Panel mount, snap-in installation with matching 16.20mm x 16.20mm square cutout
• Termination: Solder lug connections for PCB integration
• Actuator Type and Color: Square button with white actuator for physical and aesthetic compatibility
• Voltage Ratings: Minimum 125V AC and 30V DC ratings required
• Current Rating: Minimum 3A (AC/DC) required; higher ratings are acceptable
• Environmental Compliance: ROHS3 compliance required

The substitute part UB25KKW01N-B from NKK Switches meets all these criteria while offering enhanced electrical life specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The UB25KKW01N-B from NKK Switches is a direct functional substitute for the obsolete LP2S-26S-W-Z. Both components share identical circuit topology, voltage ratings, mounting interface, and termination style. The substitute part provides superior current handling capacity (5A versus 3A), extended operating temperature range (-20°C to 70°C versus -15°C to 60°C), and active product status ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and are suitable for equivalent electrical and mechanical integration. The substitute part's higher current rating provides additional design margin without compromising compatibility. Selection of UB25KKW01N-B is appropriate for replacement applications and new designs requiring DPDT pushbutton switch functionality with the specified panel mount configuration.

Frequently Asked Questions (FAQ)

Q: Can UB25KKW01N-B directly replace LP2S-26S-W-Z in existing designs?

A: Yes. Both components share identical DPDT circuit configuration, On-Momentary switch function, 125V AC / 30V DC voltage ratings, panel mount snap-in mounting with 16.20mm x 16.20mm square cutout, white square button actuator, and solder lug termination. Physical and electrical integration is equivalent.

Q: What is the significance of the higher 5A current rating on the substitute part?

A: The UB25KKW01N-B is rated for 5A compared to the original 3A rating. This higher current capacity provides additional design margin and is fully backward compatible with applications originally specified for 3A operation. No circuit modifications are required.

Q: Are there packaging differences between these parts?

A: The LP2S-26S-W-Z is specified with standard packaging, while UB25KKW01N-B is supplied in bulk packaging. Both use identical solder lug termination and panel mount snap-in configuration. Packaging format does not affect electrical or mechanical compatibility.

Q: Why does the substitute part have lower electrical life (10,000 cycles versus 30,000 cycles)?

A: The electrical life specification difference reflects manufacturer testing standards and application profiles. Both parts exceed typical industrial pushbutton switch duty cycles for standard control applications. Selection should be based on specific application cycle requirements.

Q: Is ROHS3 compliance maintained with the substitute part?

A: Yes. Both LP2S-26S-W-Z and UB25KKW01N-B are ROHS3 compliant, ensuring equivalent environmental and regulatory compliance for applications requiring restricted substance adherence.

Q: What is the advantage of the substitute part's extended temperature range?

A: UB25KKW01N-B operates from -20°C to 70°C compared to -15°C to 60°C for the original part. The extended range provides compatibility with applications requiring broader environmental operating conditions without component substitution.
