KB15MKW01-5F12-JB Equivalent & Substitute Parts

Part Overview

The KB15MKW01-5F12-JB is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is designed for panel-mounted, snap-in applications with LED green illumination at 12VDC nominal. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15MKW01-5F12-JB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Voltage rating - AC (125V minimum)
• Voltage rating - DC (30V minimum)
• Illumination type and color (LED, Green)
• Illumination voltage (12VDC nominal)
• Mounting type (Panel Mount, Snap-In)
• Actuator type (Round, Button)
• Termination compatibility with solder lug applications

Allowable Variation Parameters:

• Current rating (may exceed 1A)
• Mechanical and electrical life cycles (may exceed specified values)
• Panel cutout diameter (physical panel modification may be required)
• Product status (active products acceptable for obsolete replacements)

The YB15MKW01-5F12-JB meets all mandatory compatibility parameters while providing enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB15MKW01-5F12-JB is a direct functional substitute for the obsolete KB15MKW01-5F12-JB. Both components maintain identical electrical specifications for AC/DC voltage ratings, circuit configuration, and illumination characteristics. The substitute part is manufactured by the same supplier and carries equivalent regulatory compliance (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification).

The YB15MKW01-5F12-JB provides enhanced performance with 3A current rating versus 1A, 1,000,000 mechanical cycles versus 100,000, and 100,000 electrical cycles versus 50,000. These improvements ensure greater reliability margin in applications originally designed for the KB15MKW01-5F12-JB.

Physical integration requires consideration of panel cutout diameter differences: the substitute requires a 16.00mm circular cutout compared to the original 12.30mm specification. Termination options differ, with the substitute offering both solder and quick connect configurations in addition to solder lug compatibility.

Frequently Asked Questions (FAQ)

Q: Can the YB15MKW01-5F12-JB directly replace the KB15MKW01-5F12-JB without circuit modifications?

A: Electrical substitution is direct. Both components share identical SPDT circuit configuration, 125V AC and 30V DC voltage ratings, and 12VDC LED green illumination specifications. No circuit modifications are required for electrical compatibility.

Q: What is the impact of the larger panel cutout diameter on the YB15MKW01-5F12-JB?

A: The substitute requires a 16.00mm circular panel cutout versus the original 12.30mm diameter. Existing panel openings must be enlarged to accommodate the larger component body. This is a mechanical integration consideration only and does not affect electrical performance.

Q: Are the termination differences between solder lug and quick connect options significant?

A: The KB15MKW01-5F12-JB uses solder lug termination exclusively. The YB15MKW01-5F12-JB offers solder lug, solder, and quick connect (0.110" / 2.8mm) options. For direct replacement in existing solder lug applications, the solder lug termination option of the substitute maintains identical connection methodology.

Q: Does the higher current rating of the YB15MKW01-5F12-JB affect compatibility?

A: The 3A rating of the substitute exceeds the original 1A specification. This provides additional current-handling capacity and does not create compatibility issues in applications designed for 1A operation. The substitute is suitable for applications requiring up to 3A at the specified voltage ratings.

Q: Are both components RoHS and REACH compliant?

A: Both the KB15MKW01-5F12-JB and YB15MKW01-5F12-JB are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements for electronic component applications.
