KB16SKW01-EB Equivalent & Substitute Parts

Part Overview

The KB16SKW01-EB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with on-on switch function. This component is rated for 1A at 125V AC and 30V DC, with a yellow square button actuator and solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and design continuity in applications requiring equivalent switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16SKW01-EB is determined by the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Panel Mount, Front
• Actuator type: Square, Button
• Operating temperature range: -25°C ~ 70°C
• Voltage rating: 125V AC minimum, 30V DC minimum

Allowable Variations:

• Current rating may exceed 1A (higher current capacity is acceptable)
• Mechanical and electrical life may exceed specified values
• Panel cutout diameter may differ if mechanical redesign is feasible
• Termination style may vary if electrical connection is maintained
• Product status may differ (active products are preferred for obsolete replacements)

The YB16SKW01-EB meets all mandatory matching criteria while providing enhanced performance characteristics in current rating, mechanical life, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-EB is a suitable substitute for the obsolete KB16SKW01-EB based on the following factors:

Functional Compatibility: Both components share identical circuit configuration (SPDT), switch function (On-On), voltage ratings (125V AC / 30V DC), and operating temperature range (-25°C ~ 70°C). Both are manufactured by NKK Switches with panel mount, front configuration and yellow square button actuators.

Performance Enhancement: The YB16SKW01-EB provides superior electrical and mechanical characteristics with 3A current rating (versus 1A), 200,000 cycle mechanical life (versus 100,000), and 100,000 cycle electrical life (versus 50,000). These enhancements ensure extended component reliability without compromising original application requirements.

Product Status Advantage: The YB16SKW01-EB is active in production, ensuring long-term availability and supply chain continuity compared to the obsolete KB16SKW01-EB.

Design Considerations: The panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel redesign. Termination style changes from solder lug to solder with quick connect option, requiring electrical connection modification. Both changes are manageable in redesign scenarios.

Compliance: The KB16SKW01-EB is ROHS3 compliant. Compliance status for the YB16SKW01-EB is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-EB directly replace the KB16SKW01-EB without any modifications?

A: Electrical and functional replacement is direct. However, mechanical panel modifications are required due to the larger 16.00mm cutout diameter (versus 12.30mm) and termination style change from solder lug to solder with quick connect. These modifications must be evaluated for your specific application.

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

A: The primary differences are current rating (1A versus 3A), mechanical life (100,000 versus 200,000 cycles), electrical life (50,000 versus 100,000 cycles), panel cutout diameter (12.30mm versus 16.00mm), and termination style (solder lug versus solder with quick connect). Circuit configuration, voltage ratings, and operating temperature range are identical.

Q: Is the higher current rating of the YB16SKW01-EB a concern for applications designed for 1A?

A: No. Higher current rating indicates greater capacity and does not negatively impact applications designed for lower current. The component will operate safely within the original 1A specification.

Q: What is the impact of the different panel cutout dimensions?

A: The YB16SKW01-EB requires a larger circular cutout of 16.00mm diameter compared to the KB16SKW01-EB's 12.30mm diameter. This necessitates mechanical panel redesign or modification to accommodate the larger component footprint.

Q: Are there any compliance or certification differences?

A: The KB16SKW01-EB is confirmed ROHS3 compliant. RoHS compliance status for the YB16SKW01-EB is not specified in available technical documentation and should be confirmed with the manufacturer if compliance is a requirement.

Q: How do the termination styles differ and what does this mean for installation?

A: The KB16SKW01-EB uses solder lug termination, while the YB16SKW01-EB offers solder termination with quick connect option (0.110" / 2.8mm). This provides greater flexibility in connection methods but requires electrical connection redesign from the original solder lug configuration.
