LP1W-16S-W-Z Equivalent & Substitute Parts

Part Overview

The LP1W-16S-W-Z is a pushbutton switch manufactured by Nidec Components Corporation, configured as a Standard SPDT (Single Pole Double Throw) switch with On-Momentary function. This component is rated for 3A at 125V AC and 30V DC, featuring a white rectangular button actuator with PC pin termination for through-hole mounting. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The UB15SKW03N-B from NKK Switches qualifies as a substitute based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• Voltage rating - AC: 125V
• Voltage rating - DC: 30V
• Mounting type: Through Hole
• Actuator color: White
• Termination style: PC Pin
• RoHS compliance: ROHS3 Compliant

Differing Parameters:

• Current rating: 5A (exceeds 3A requirement)
• Actuator type: Square button (versus rectangular)
• Operating temperature: -20°C to 70°C (wider range)
• Electrical life: 10,000 cycles (lower than 30,000)
• Mechanical life: 1,000,000 cycles (specified)
• Product status: Active

The UB15SKW03N-B maintains electrical compatibility through matching voltage and circuit specifications while providing higher current capacity, making it suitable for direct substitution in applications where the original LP1W-16S-W-Z is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The UB15SKW03N-B is an active product from an established manufacturer, providing continuity for applications previously using the obsolete LP1W-16S-W-Z. Both components maintain ROHS3 compliance and equivalent electrical ratings for AC voltage operation at 125V and DC voltage at 30V. The substitute part offers higher current capacity (5A versus 3A), which provides design margin for existing circuits. The wider operating temperature range (-20°C to 70°C) accommodates broader environmental conditions compared to the original part. Physical mounting compatibility is maintained through identical through-hole PC pin termination. The substitute's active product status ensures ongoing availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can UB15SKW03N-B directly replace LP1W-16S-W-Z in existing designs?

A: Yes. Both components share identical SPDT circuit configuration, On-Momentary function, 125V AC and 30V DC voltage ratings, through-hole mounting, and PC pin termination. The substitute's higher 5A current rating is compatible with circuits designed for 3A operation.

Q: What is the difference in actuator design between these parts?

A: The LP1W-16S-W-Z features a rectangular button actuator, while the UB15SKW03N-B uses a square button actuator. Both are white and function identically in On-Momentary operation. Physical panel cutout dimensions should be verified for mechanical fit in existing enclosures.

Q: How do the electrical life ratings compare?

A: The LP1W-16S-W-Z is rated for 30,000 electrical cycles, while the UB15SKW03N-B is rated for 10,000 electrical cycles. Applications requiring extended cycle life should account for this difference in maintenance planning.

Q: Are both parts RoHS compliant?

A: Yes. Both the LP1W-16S-W-Z and UB15SKW03N-B are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the packaging difference?

A: The LP1W-16S-W-Z is supplied in standard packaging, while the UB15SKW03N-B is supplied in trays. This affects handling and storage procedures but does not impact component functionality.
