Key Parameters

Substitute Part Grouping Explanation

The UB15SKW035D-JD from NKK Switches qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• SPDT circuit configuration
• On-Momentary switch function
• 125V AC voltage rating
• 30V DC voltage rating
• Through Hole mounting type
• Square button actuator
• LED illumination capability
• PC Pin termination style
• ROHS3 compliance
• PC Pin termination

Allowable Variations:

• Current rating: 5A (exceeds 3A requirement, acceptable for higher capacity applications)
• Illumination voltage: 2VDC nominal (compatible with 2.2VDC specification within typical LED operating margins)
• Illumination color: Amber with clear diffuser (functionally equivalent to yellow LED)
• Operating temperature: -25°C to 50°C (overlaps primary operating range)
• Electrical life: 10,000 cycles (lower than original 30,000 cycles; acceptable for applications not requiring extended cycle life)
• Mechanical life: 1,000,000 cycles (significantly exceeds original specification)
• Product status: Active (ensures ongoing availability)

Parameter Comparison

Engineering Selection Recommendations

The UB15SKW035D-JD is suitable as a direct substitute for the LP1S-16S-889-Z in applications where the following conditions are met:

• Circuit requirements are limited to SPDT configuration with On-Momentary operation
• System voltage does not exceed 125V AC or 30V DC
• Current draw does not exceed 5A
• Through Hole mounting and PC Pin termination are compatible with existing PCB layouts
• Operating environment remains within -25°C to 50°C range
• Electrical cycle life requirement does not exceed 10,000 cycles

The UB15SKW035D-JD offers advantages including active product status, higher mechanical life rating (1,000,000 cycles), and extended lower temperature operating range (-25°C versus -15°C). The substitute maintains full ROHS3 compliance and equivalent termination methodology.

Frequently Asked Questions (FAQ)

Q: Can the UB15SKW035D-JD replace the LP1S-16S-889-Z in all applications?

A: The UB15SKW035D-JD is functionally equivalent for applications operating within the specified electrical and mechanical parameters. Primary consideration is electrical cycle life: the substitute is rated for 10,000 cycles versus the original 30,000 cycles. Applications requiring extended cycle life should evaluate this parameter against actual usage patterns.

Q: What is the difference in illumination between yellow and amber LEDs?

A: Both yellow and amber LEDs provide similar visual indication in the 590-610nm wavelength range. The UB15SKW035D-JD uses an amber LED with a clear diffuser, functionally equivalent to the yellow LED in the original component. Visual appearance may differ slightly under specific lighting conditions.

Q: Are the illumination voltages compatible?

A: The original component operates at 2.2VDC nominal, while the substitute operates at 2VDC nominal. This 0.2V difference is within typical LED operating tolerances and does not affect functional compatibility in standard circuit implementations.

Q: What packaging differences exist between these parts?

A: The LP1S-16S-889-Z does not specify packaging format. The UB15SKW035D-JD is supplied in Tray packaging. Both components use identical PC Pin termination and Through Hole mounting, ensuring mechanical compatibility with existing PCB designs.

Q: Why is the original part obsolete?

A: The LP1S-16S-889-Z is classified as obsolete by the manufacturer. The UB15SKW035D-JD from NKK Switches maintains active product status, ensuring continued availability and supply chain reliability for new designs and maintenance applications.

Q: Are there temperature range considerations for substitution?

A: The original component operates from -15°C to 60°C. The substitute operates from -25°C to 50°C. The substitute provides extended low-temperature capability but has a reduced upper temperature limit of 50°C versus 60°C. Verify that your application's maximum operating temperature does not exceed 50°C.
