Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP1S-17S-K-Z are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Voltage rating: 125V AC minimum
• Mounting type: Through Hole
• Termination style: PC Pin
• Actuator type: Square, Button

Secondary Compatibility Factors:

• Current rating equal to or greater than 3A
• Operating temperature range that encompasses or exceeds the original specification
• RoHS3 compliance for regulatory alignment

The UB16SKW03N-A from NKK Switches meets all primary matching criteria and exceeds performance specifications in current rating (5A vs 3A) and mechanical life (200,000 cycles vs unspecified), making it a valid substitute for the obsolete LP1S-17S-K-Z.

Parameter Comparison

Engineering Selection Recommendations

The UB16SKW03N-A is suitable as a substitute for the LP1S-17S-K-Z based on the following engineering factors:

Electrical Compatibility: Both components share identical SPDT circuit configuration, On-On switch function, 125V AC and 30V DC voltage ratings, and PC Pin termination. The UB16SKW03N-A provides higher current capacity (5A vs 3A), which is compatible with applications designed for the original 3A specification.

Mechanical Compatibility: Both switches feature identical through-hole mounting and square button actuator design with black coloring, ensuring direct PCB footprint compatibility.

Regulatory Compliance: Both components maintain ROHS3 compliance, supporting continued use in regulated applications.

Product Status Advantage: The UB16SKW03N-A is active in production, providing long-term availability and supply chain stability compared to the obsolete LP1S-17S-K-Z.

Operating Environment: The UB16SKW03N-A extends the operating temperature range (-20°C ~ 70°C vs -15°C ~ 60°C), offering broader environmental tolerance.

Frequently Asked Questions (FAQ)

Q: Can the UB16SKW03N-A directly replace the LP1S-17S-K-Z on existing PCBs?

A: Yes. Both components share identical through-hole mounting configuration, PC Pin termination style, and square button actuator design. No PCB modifications are required for physical installation.

Q: Are the electrical ratings compatible?

A: Yes. The UB16SKW03N-A meets or exceeds all electrical specifications of the LP1S-17S-K-Z. It maintains the same 125V AC and 30V DC voltage ratings and SPDT circuit configuration. The higher current rating (5A vs 3A) is compatible with applications designed for the original component.

Q: What is the difference in electrical life between these components?

A: The LP1S-17S-K-Z specifies 30,000 electrical cycles, while the UB16SKW03N-A specifies 10,000 electrical cycles. Application requirements should determine if this difference impacts component selection for cycle-intensive environments.

Q: Are both components RoHS compliant?

A: Yes. Both the LP1S-17S-K-Z and UB16SKW03N-A are ROHS3 compliant, supporting use in regulated markets and applications with RoHS requirements.

Q: What packaging is available for the substitute part?

A: The UB16SKW03N-A is supplied in bulk packaging, differing from the original component's packaging specification.
