LP2S-26S-K-Z Equivalent & Substitute Parts
Part Overview
The LP2S-26S-K-Z is a pushbutton switch manufactured by Nidec Components Corporation, configured as a DPDT (Double Pole Double Throw) standard panel mount, snap-in component with On-Mom switch function. This part is rated for 3A at 125V AC and 30V DC, featuring a square black button actuator with solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Substitute Part Grouping Explanation
Substitution of the LP2S-26S-K-Z is determined by strict alignment of the following critical parameters:
Mandatory Matching Parameters:
- Circuit Configuration: DPDT
- Switch Function: On-Mom
- Voltage Rating - AC: 125V
- Voltage Rating - DC: 30V
- Mounting Type: Panel Mount, Snap-In
- Actuator Type: Square, Button
- Termination Style: Solder Lug
- Panel Cutout Dimensions: Square - 16.20mm x 16.20mm
Allowable Variation Parameters:
- Current Rating: May exceed 3A (higher current rating is acceptable for backward compatibility)
- Operating Temperature Range: May exceed the original range
- Electrical Life: May exceed 30,000 cycles
- Mechanical Life: May exceed original specification
- Product Status: Active status preferred for ongoing availability
The UB25KKW01N-A from NKK Switches qualifies as a substitute based on matching all mandatory parameters while providing enhanced specifications in current rating (5A), operating temperature range (-20°C ~ 70°C), and mechanical life (1,000,000 cycles).

Engineering Selection Recommendations
The UB25KKW01N-A is a qualified substitute for the obsolete LP2S-26S-K-Z based on electrical and mechanical parameter alignment. Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility.
The substitute part provides enhanced specifications: higher current rating (5A versus 3A), extended operating temperature range (-20°C ~ 70°C versus -15°C ~ 60°C), and superior mechanical life (1,000,000 cycles). These enhancements support broader application flexibility without compromising the original design requirements.
The UB25KKW01N-A is currently in active production status with documented inventory availability, addressing the obsolescence of the original component. The identical panel cutout dimensions (16.20mm x 16.20mm square) and matching termination style (solder lug) ensure direct mechanical and electrical integration into existing panel assemblies and PCB layouts.
Frequently Asked Questions (FAQ)
Q: Can the UB25KKW01N-A directly replace the LP2S-26S-K-Z in existing designs?
A: Yes. Both components share identical DPDT circuit configuration, On-Mom switch function, 125V AC / 30V DC voltage ratings, panel mount snap-in mounting, square button actuator, solder lug termination, and 16.20mm x 16.20mm panel cutout dimensions. The substitute part integrates directly into existing mechanical and electrical interfaces.
Q: What are the key differences between these two parts?
A: The UB25KKW01N-A provides higher current rating (5A versus 3A), extended operating temperature range (-20°C ~ 70°C versus -15°C ~ 60°C), and documented mechanical life (1,000,000 cycles). The original part specifies 30,000 electrical life cycles, while the substitute specifies 10,000 electrical life cycles. The substitute is in active production; the original is obsolete.
Q: Are both parts RoHS compliant?
A: Yes. Both the LP2S-26S-K-Z and UB25KKW01N-A are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.
Q: Does the higher current rating of the substitute part affect circuit design?
A: No. The
