KB16RKW01B Equivalent & Substitute Parts

Part Overview

The KB16RKW01B is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with On-On switching function. This component is rated for 1A at 125V AC and 30V DC, with a panel mount front configuration and solder lug termination. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16RKW01B is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Voltage rating (125V AC minimum, 30V DC)
• Mounting type (Panel Mount, Front)
• Operating temperature range (-25°C to 70°C)

Allowable Variation Parameters:

• Current rating: The substitute may exceed the original 1A specification, provided it meets or exceeds the minimum requirement
• Mechanical and electrical life: Higher cycle ratings are acceptable
• Termination style: Variations in termination are permissible if electrical connection is maintained
• Panel cutout dimensions: May differ if mechanical integration is feasible

The YB16RKW01 qualifies as a substitute based on matching SPDT circuit configuration, On-On function, identical voltage ratings, equivalent mounting type, and identical operating temperature range. The higher current rating (3A), extended mechanical life (200,000 cycles), and enhanced electrical life (100,000 cycles) represent improvements over the original specification.

Parameter Comparison

Engineering Selection Recommendations

The YB16RKW01 is suitable for applications requiring KB16RKW01B functionality. The substitute maintains identical electrical specifications for voltage and circuit configuration while providing enhanced current capacity and extended operational life ratings. Both components are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

The transition from obsolete KB16RKW01B to active YB16RKW01 status provides supply chain continuity. The YB16RKW01 is currently in active production with 1160 units in stock, compared to the KB16RKW01B's obsolete status with 915 units remaining.

Mechanical integration considerations include panel cutout diameter differences: KB16RKW01B requires 12.30mm circular cutout, while YB16RKW01 requires 16.00mm circular cutout. Termination style variation (solder lug versus solder/quick connect) requires electrical connection verification during integration.

Frequently Asked Questions (FAQ)

Q: Can YB16RKW01 directly replace KB16RKW01B in existing designs?

A: Electrical compatibility is confirmed for SPDT On-On switching at 125V AC and 30V DC. Panel cutout diameter and termination style differences require mechanical and electrical integration assessment.

Q: What are the key differences between these components?

A: The YB16RKW01 provides higher current capacity (3A versus 1A), extended mechanical life (200,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles). Both maintain identical voltage ratings and operating temperature range.

Q: Is the higher current rating of YB16RKW01 a concern for existing circuits?

A: No. Higher current rating indicates greater capacity and does not negatively impact circuits designed for lower current. The component will operate safely in applications rated for 1A or lower.

Q: What is the significance of product status change from Obsolete to Active?

A: Active status indicates ongoing manufacturing and supply availability. This ensures long-term component sourcing for maintenance and production requirements.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent.

Q: How do panel cutout dimensions affect substitution?

A: Panel cutout diameter increases from 12.30mm to 16.00mm. Mechanical panel integration requires verification that the larger cutout is compatible with existing panel designs or can be modified.
