Key Parameters

Substitute Part Grouping Explanation

The YB15KKW01-5C-JC qualifies as a substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: SPDT maintained
• Switch function: On-Mom (momentary) operation preserved
• Mounting type: Panel Mount, Snap-In compatible
• Actuator type: Square button maintained
• Voltage rating - AC: 125V identical
• Voltage rating - DC: 30V identical
• Operating temperature range: -25°C to 50°C identical
• Termination style: Solder-based connection maintained
• RoHS3 compliance: Both parts compliant
• REACH status: Both parts unaffected

Substitution Basis: The YB15KKW01-5C-JC provides enhanced electrical performance (3A current rating versus 1A) and improved mechanical durability (1,000,000 cycles versus 100,000 cycles), while maintaining identical voltage specifications and mounting configuration. The substitute part is active in production, addressing the obsolescence of the original KB15KKW01-01-JC.

Parameter Comparison

Engineering Selection Recommendations

The YB15KKW01-5C-JC is the designated substitute for KB15KKW01-01-JC applications. Selection of this substitute is supported by:

• Product Status Alignment: The substitute part is active in production, ensuring long-term availability and supply chain continuity, whereas the original part is obsolete.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.
• Electrical Specification Compatibility: Identical AC/DC voltage ratings (125V AC, 30V DC) ensure direct functional compatibility in existing circuit designs.
• Mechanical Compatibility: Identical mounting type (Panel Mount, Snap-In) and operating temperature range (-25°C to 50°C) support direct installation in existing mechanical assemblies.

Design Considerations: Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. Illumination technology transitions from neon (110 VAC) to LED (1.9 VDC), necessitating circuit redesign for the illumination supply. Current rating upgrade (1A to 3A) and mechanical life improvement (100,000 to 1,000,000 cycles) provide enhanced performance margins.

Frequently Asked Questions (FAQ)

Q: Can YB15KKW01-5C-JC be used as a direct drop-in replacement for KB15KKW01-01-JC?

A: Electrical and functional compatibility is confirmed. Mechanical panel modification is required due to increased cutout diameter (16.00mm versus 12.30mm). Illumination circuit redesign is necessary due to technology change from neon to LED and voltage change from 110 VAC to 1.9 VDC.

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

A: Current rating increases from 1A to 3A. Mechanical life extends from 100,000 to 1,000,000 cycles. Electrical life increases from 50,000 to 100,000 cycles. Illumination technology changes from neon to LED. Panel cutout diameter increases from 12.30mm to 16.00mm. Illumination voltage changes from 110 VAC to 1.9 VDC.

Q: Are both parts compliant with environmental regulations?

A: Both KB15KKW01-01-JC and YB15KKW01-5C-JC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
