Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15MKW01-28-EB is determined by the following critical parameters:

Electrical Compatibility Requirements:

• SPDT circuit configuration (maintained)
• AC voltage rating of 125V minimum (maintained)
• DC voltage rating of 30V minimum (maintained)
• Switch function: On-Momentary operation (maintained)

Mechanical Compatibility Requirements:

• Panel mount, snap-in mounting type (maintained)
• Circular panel cutout diameter compatibility
• Solder lug or equivalent termination style

Environmental & Compliance Requirements:

• Operating temperature range: -25°C to 50°C (maintained)
• RoHS3 compliance (maintained)
• REACH unaffected status (maintained)

The substitute part YB15MKW01-5D24-JD meets these core substitution criteria while introducing enhanced performance characteristics in current rating, mechanical life, and electrical life specifications.

Parameter Comparison

Engineering Selection Recommendations

The YB15MKW01-5D24-JD is an active product with current manufacturing support, whereas the KB15MKW01-28-EB is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for electronic component deployment.

The substitute part provides enhanced electrical and mechanical performance with a 3A current rating versus 1A, and 1,000,000 mechanical cycles versus 100,000 cycles. The illumination system transitions from incandescent yellow (28 VAC) to LED amber (24 VDC), requiring circuit-level evaluation for power supply compatibility.

Panel cutout diameter increases from 12.30mm to 16.00mm, necessitating mechanical redesign of panel mounting interfaces. Termination style changes from solder lug to solder with quick connect options, requiring harness and PCB layout modifications.

Selection of the YB15MKW01-5D24-JD is appropriate for applications requiring extended component lifecycle support and enhanced durability specifications.

Frequently Asked Questions (FAQ)

Q: Can the YB15MKW01-5D24-JD directly replace the KB15MKW01-28-EB without modifications?

A: Direct mechanical replacement is not possible due to panel cutout diameter differences (12.30mm versus 16.00mm). Electrical substitution requires evaluation of illumination voltage compatibility (28 VAC incandescent versus 24 VDC LED) and termination style changes (solder lug versus solder/quick connect).

Q: What are the critical electrical parameters for substitution?

A: SPDT circuit configuration, 125V AC and 30V DC voltage ratings, and On-Momentary switch function must be maintained. The substitute part meets these requirements with enhanced current capacity (
