KB15SKW01-5C-JC Equivalent & Substitute Parts

Part Overview

The KB15SKW01-5C-JC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with illuminated panel mount design. This component is rated for 1A at 125V AC and includes red LED illumination at 1.9VDC nominal. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this series is no longer available through standard procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-5C-JC is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Voltage ratings (125V AC / 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Illumination type and color (LED, Red)
• Illumination voltage (1.9VDC nominal)
• Operating temperature range (-25°C to 50°C)
• Compliance certifications (RoHS3, REACH Unaffected)

Allowable Variation Parameters:

• Current rating (may exceed 1A specification)
• Mechanical and electrical life cycles (may exceed minimum values)
• Panel cutout diameter (physical accommodation dependent)
• Termination style (electrical compatibility dependent)
• Product status (active preferred over obsolete)

The YB15SKW01-5C-JC qualifies as a substitute based on matching all mandatory parameters while providing enhanced performance characteristics in current rating, mechanical life, and electrical life specifications.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C-JC is a qualified substitute for the obsolete KB15SKW01-5C-JC based on functional equivalence across all critical electrical and mechanical parameters. Both components maintain identical voltage ratings, circuit configuration, and illumination specifications required for direct functional replacement.

The YB15SKW01-5C-JC offers enhanced reliability characteristics with 10x greater mechanical life (1,000,000 vs. 100,000 cycles) and 2x greater electrical life (100,000 vs. 50,000 cycles). Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

Physical integration requires consideration of the increased panel cutout diameter (16.00mm vs. 12.30mm). The YB series features tactile feedback and supports multiple termination options (Solder and Quick Connect 0.110"), providing design flexibility compared to the KB series solder lug termination.

Frequently Asked Questions (FAQ)

Q: Can YB15SKW01-5C-JC directly replace KB15SKW01-5C-JC in existing designs?

A: Electrical and functional replacement is direct. Physical panel integration requires verification that the 16.00mm cutout diameter accommodates the larger YB series actuator housing. Termination compatibility must be confirmed; the YB series offers solder and quick connect options versus the KB series solder lug configuration.

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

A: The primary differences are current rating (3A vs. 1A), mechanical life (1,000,000 vs. 100,000 cycles), electrical life (100,000 vs. 50,000 cycles), panel cutout diameter (16.00mm vs. 12.30mm), and product status (active vs. obsolete). All voltage ratings, circuit configuration, and illumination specifications are identical.

Q: Why is the YB15SKW01-5C-JC rated for higher current?

A: The YB series represents an enhanced product line with improved performance specifications. The 3A current rating provides design margin for applications requiring higher switching capacity while maintaining compatibility with lower-current legacy designs.

Q: Are there packaging differences between these parts?

A: The KB15SKW01-5C-JC ships in standard packaging, while the YB15SKW01-5C-JC is supplied in tray packaging. This affects procurement and handling procedures but does not impact electrical or mechanical performance.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory requirements for electronic component procurement and deployment.
