KB15SKW01-EB Equivalent & Substitute Parts

Part Overview

The KB15SKW01-EB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC and 30V DC. This component is designed for standard panel mount, front installation applications with a square button actuator in yellow with white filter/diffuser. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-EB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (momentary operation)
• Mounting type must be Panel Mount, Front
• Actuator type must be Square, Button
• Operating temperature range must encompass -25°C to 70°C
• Voltage ratings must meet or exceed 125V AC and 30V DC
• Current rating must meet or exceed 1A (AC/DC)
• RoHS3 compliance required

Allowable Variations:

• Current rating may exceed 1A
• Mechanical and electrical life cycles may exceed specified minimums
• Termination style may differ (Solder Lug, Quick Connect, or equivalent)
• Panel cutout diameter may increase to accommodate larger actuators
• Product status may be Active (preferred for new sourcing)

The YB15SKW01-EB qualifies as a direct substitute based on these parameters, offering enhanced performance characteristics while maintaining functional equivalence.

Engineering Selection Recommendations

The YB15SKW01-EB is a qualified substitute for the obsolete KB15SKW01-EB based on functional equivalence and regulatory compliance. Selection considerations are as follows:

Advantages of YB15SKW01-EB:

• Active product status ensures ongoing availability and supply chain continuity
• Current rating of 3A provides 300% margin over the original 1A specification
• Mechanical life of 1,000,000 cycles and electrical life of 100,000 cycles represent significant improvements in component longevity
• ROHS3 compliance maintained
• Identical voltage ratings, circuit configuration, and switch function
• Tactile feedback feature enhances user interface responsiveness

Design Considerations:

• Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical redesign of panel mounting interface
• Termination style includes Quick Connect option (0.110" / 2.8mm) in addition to solder capability, offering installation flexibility
• Packaging format changes from standard to tray configuration

For applications where panel cutout modification is not feasible, alternative substitutes within the NKK Switches portfolio meeting the mandatory compatibility parameters should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can YB15SKW01-EB directly replace KB15SKW01-EB without circuit modifications?

A: Yes, from an electrical standpoint. Both components feature identical SPDT circuit configuration, On-Mom switch function, and voltage/current ratings (with YB15SKW01-EB providing higher current capacity). However, the panel cutout diameter difference (12.30mm vs. 16.00mm) requires mechanical panel modification.

Q: What is the significance of the current rating increase from 1A to 3A?

A: The YB15SKW01-EB's 3A rating indicates the component can safely handle higher switching currents. This provides design margin and allows the substitute to function in applications with current demands up to 3A, while remaining fully compatible with circuits designed for 1A operation.

Q: Are there termination compatibility issues between Solder Lug and Quick Connect options?

A: The YB15SKW01-EB offers both Solder and Quick Connect termination styles. Solder Lug termination is compatible with the original KB15SKW01-EB wiring approach. Quick Connect termination (0.110" / 2.8mm) provides an alternative connection method suitable for applications using standard quick-connect receptacles.

Q: Does the increased mechanical life (1,000,000 vs. 100,000 cycles) affect compatibility?

A: No. Higher mechanical life represents improved component durability and is not a compatibility constraint. The substitute will function identically in applications designed for the original 100,000-cycle specification.

Q: What packaging format differences exist between these components?

A: KB15SKW01-EB uses standard packaging, while YB15SKW01-EB is supplied in tray format. This affects procurement and handling procedures but does not impact electrical or mechanical compatibility.

Q: Are both components RoHS compliant?

A: Yes. Both KB15SKW01-EB and YB15SKW01-EB maintain ROHS3 compliance, ensuring regulatory alignment for applications subject to RoHS requirements.
