LP1S-27S-229-Z Equivalent & Substitute Parts

Part Overview

The LP1S-27S-229-Z is a pushbutton switch manufactured by Nidec Components Corporation, configured as a DPDT (Double Pole Double Throw) standard illuminated through-hole component. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The switch is rated for 3A at 125V AC and features red LED illumination with a square button actuator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP1S-27S-229-Z is determined by the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Voltage rating must support minimum 125V AC and 30V DC
• Mounting type must be Through Hole
• Actuator type must be Square Button
• Illumination must be LED, Red
• Termination style must be PC Pin
• RoHS3 compliance required

The UB26SKW035C-CC from NKK Switches meets all substitution criteria. While it exceeds the current rating specification (5A versus 3A), this represents an acceptable design margin for component selection. The substitute maintains identical circuit topology, voltage ratings, mounting configuration, and illumination characteristics.

Parameter Comparison

Engineering Selection Recommendations

The UB26SKW035C-CC is the qualified substitute for the obsolete LP1S-27S-229-Z. Selection of this alternative is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance matching the original component specification
• Identical electrical ratings for AC and DC voltage operation
• Matching circuit topology and switch function
• Compatible through-hole mounting and PC pin termination
• Equivalent illumination characteristics with LED red indication

The substitute component maintains functional equivalence across all critical electrical and mechanical parameters required for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the UB26SKW035C-CC directly replace the LP1S-27S-229-Z in existing PCB designs?

A: Yes. Both components feature identical through-hole mounting, PC pin termination, and panel cutout requirements. No PCB layout modifications are required.

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

A: The UB26SKW035C-CC is rated for 5A compared to the original 3A specification. This higher rating provides additional design margin and does not create compatibility issues in applications requiring 3A or less.

Q: Are the illumination voltages compatible?

A: The illumination voltages differ slightly (2 VDC original versus 1.85 VDC substitute). Both operate within standard LED circuit tolerances and are compatible with typical illumination drive circuits.

Q: What is the impact of the different operating temperature ranges?

A: The substitute operates across -25°C to 50°C versus the original -15°C to 60°C. Applications operating within the substitute's temperature range experience no functional impact. Applications requiring operation above 50°C or below -25°C must retain the original specification or identify alternative solutions.

Q: How do the electrical life ratings compare?

A: The original component specifies 30,000 cycles while the substitute specifies 10,000 cycles. Applications with cycle count requirements exceeding 10,000 must evaluate this parameter against actual operational demands.

Q: Is packaging compatibility a consideration?

A: The substitute is supplied in tray packaging. Verify that receiving, handling, and storage procedures accommodate this packaging format within your supply chain operations.
