KB15SKW01-01-JC Equivalent & Substitute Parts

Part Overview

The KB15SKW01-01-JC is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. This illuminated panel mount switch features a square button actuator with red neon illumination and is designed for front panel mounting with a circular 12.30mm diameter cutout. The product is classified as obsolete, making identification of suitable substitute components necessary for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

The YB15SKW01-5C12-JC qualifies as a substitute for the KB15SKW01-01-JC based on the following alignment of critical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Voltage rating - AC: 125V
• Voltage rating - DC: 30V
• Mounting type: Panel Mount, Front
• Actuator type: Square, Button
• Operating temperature range: -25°C to 50°C
• RoHS compliance: ROHS3 Compliant
• Termination compatibility: Both use solder-based connections

Substitution Basis: The YB15SKW01-5C12-JC maintains functional equivalence through identical circuit topology, voltage ratings, and operating parameters. The substitute part is manufactured by the same supplier (NKK Switches) and shares the same mechanical mounting interface and environmental specifications. The substitute is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C12-JC is suitable as a substitute for the KB15SKW01-01-JC in applications where the following conditions are met:

Electrical Compatibility: The substitute maintains identical AC and DC voltage ratings (125V AC / 30V DC) and SPDT circuit topology. The higher current rating (3A versus 1A) provides additional design margin and does not create incompatibility with the original specification.

Mechanical Integration: Panel cutout modification is required. The substitute requires a 16.00mm diameter circular cutout compared to the original 12.30mm specification. Existing panel mounting holes must be evaluated for compatibility with the larger diameter requirement.

Illumination Considerations: The substitute employs LED red illumination powered at 12 VDC, replacing the original neon illumination at 110 VAC. This requires independent illumination circuit design and power supply modification. The visual output (red color) remains consistent with the original design intent.

Compliance and Support: Both components maintain ROHS3 compliance and EAR99 ECCN classification. The substitute is classified as active product status, ensuring manufacturer support, documentation availability, and continued supply chain access. The original part is obsolete, limiting future procurement options.

Lifecycle Advantages: The substitute offers extended mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), providing improved reliability for long-term applications.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C12-JC be used as a direct drop-in replacement for the KB15SKW01-01-JC?

A: Electrical and functional compatibility is confirmed. Physical panel integration requires modification due to the larger 16.00mm cutout diameter. Illumination circuit redesign is necessary due to different voltage and technology requirements (12 VDC LED versus 110 VAC neon).

Q: What are the key differences between these two switches?

A: The primary differences are current rating (3A versus 1A), illumination technology (LED versus neon), illumination voltage (12 VDC versus 110 VAC), panel cutout size (16.00mm versus 12.30mm), and product lifecycle status (active versus obsolete). Electrical ratings, circuit configuration, and mounting type remain identical.

Q: Is the higher current rating of the substitute a concern?

A: No. A higher current rating does not create incompatibility. The substitute can safely operate at the original 1A specification with additional design margin. This is a standard engineering practice for component substitution.

Q: What modifications are required for panel integration?

A: The panel cutout must be enlarged from 12.30mm to 16.00mm diameter. Existing mounting hardware and electrical connections require evaluation for compatibility with the larger switch body. Mechanical mounting verification is necessary before final assembly.

Q: How does the illumination change affect system design?

A: The substitute requires a dedicated 12 VDC power supply for illumination, replacing the original 110 VAC neon circuit. Circuit design must accommodate this voltage and power requirement independently from the switch contact circuit. LED illumination provides improved energy efficiency and longer operational life compared to neon technology.

Q: Are there any compliance or certification concerns with substitution?

A: Both components maintain ROHS3 compliance and identical ECCN/HTSUS classifications. No compliance barriers exist for substitution. The active product status of the substitute ensures ongoing manufacturer support and documentation availability.

Q: What is the impact of different termination options?

A: The substitute offers both solder and quick-connect 0.110" (2.8mm) termination options, providing flexibility beyond the original solder lug configuration. Existing solder connections can be maintained, or quick-connect terminals can be utilized for improved serviceability.
