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

Part Overview

The LP2S-27S-R-Z is a pushbutton switch manufactured by Nidec Components Corporation, featuring DPDT (Double Pole Double Throw) circuitry with On-On switching function. This component is rated for 3A at 125V AC and 30V DC, designed for panel mount snap-in installation with a square red button actuator. 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-27S-R-Z is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Panel Mount, Snap-In
• Actuator type: Square, Button
• Termination style: Solder Lug
• Panel cutout dimensions: Square - 16.20mm x 16.20mm
• Voltage rating - AC: 125V minimum
• Voltage rating - DC: 30V minimum
• RoHS compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Current rating: May exceed 3A (higher current capability is acceptable)
• Operating temperature range: May exceed the original range
• Electrical life: May exceed 30,000 cycles
• Product status: Active status preferred for ongoing availability

The substitute part UB26KKW01N-C from NKK Switches meets all mandatory matching parameters while providing enhanced specifications in current rating (5A), operating temperature range (-20°C to 70°C), and mechanical life (200,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The UB26KKW01N-C from NKK Switches is a direct functional substitute for the obsolete LP2S-27S-R-Z. Both components share identical electrical specifications for voltage and switching function, matching mechanical dimensions for panel installation, and equivalent termination methods.

The substitute part offers the advantage of active product status, ensuring continued availability for procurement and support. Both components maintain ROHS3 compliance, meeting current environmental and regulatory requirements.

The UB26KKW01N-C provides enhanced current rating (5A versus 3A) and extended operating temperature range (-20°C to 70°C versus -15°C to 60°C), making it suitable for applications with more demanding environmental or electrical requirements. The electrical life specification of the substitute (10,000 cycles) is lower than the original part (30,000 cycles); however, the mechanical life specification (200,000 cycles) indicates robust mechanical durability for typical panel-mounted switch applications.

Selection of the UB26KKW01N-C is appropriate for direct replacement in existing designs or new applications requiring DPDT On-On pushbutton switch functionality with panel mount snap-in installation.

Frequently Asked Questions (FAQ)

Q: Can the UB26KKW01N-C directly replace the LP2S-27S-R-Z in existing applications?

A: Yes. Both components share identical panel cutout dimensions (16.20mm x 16.20mm square), matching mounting type (panel mount snap-in), equivalent electrical ratings (125V AC, 30V DC), and identical circuit configuration (DPDT On-On). Solder lug termination is identical on both parts.

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

A: The UB26KKW01N-C is rated for 5A compared to the original 3A rating. This higher current capability does not affect compatibility; it indicates the substitute can safely handle applications requiring up to 5A without derating. Applications using 3A or less operate well within the substitute's specifications.

Q: How do the electrical life specifications compare?

A: The LP2S-27S-R-Z specifies 30,000 electrical cycles, while the UB26KKW01N-C specifies 10,000 electrical cycles. For applications with frequent switching cycles, the original part specification was higher. However, the substitute's mechanical life rating of 200,000 cycles indicates robust mechanical durability for typical panel switch applications.

Q: Are there packaging differences between these parts?

A: The LP2S-27S-R-Z packaging is not specified in available data. The UB26KKW01N-C is supplied in tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts meet current compliance standards?

A: Yes. Both the LP2S-27S-R-Z and UB26KKW01N-C are ROHS3 compliant. The substitute part carries REACH Unaffected status, confirming compliance with current environmental regulations.

Q: What is the operating temperature difference between these components?

A: The LP2S-27S-R-Z operates from -15°C to 60°C. The UB26KKW01N-C operates from -20°C to 70°C, providing a 5°C lower minimum and 10°C higher maximum operating temperature. This extended range makes the substitute suitable for applications with more demanding thermal environments.
