Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-5F24-JB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Mounting type: Panel Mount, Front
• Illumination type: LED, Green
• Illumination voltage: 24 VDC
• Operating temperature range: -25°C to 50°C

Allowable Variation Parameters:

• Current rating: May be equal to or greater than 1A
• Voltage ratings (AC/DC): Must meet or exceed specified ratings
• Panel cutout diameter: Larger cutouts are acceptable with mechanical redesign
• Mechanical and electrical life: Higher cycle ratings are acceptable
• Termination style: Alternative termination methods are acceptable if electrical connection is maintained
• Product status: Active status preferred for long-term availability

The YB15SKW01-5F24-JB meets all mandatory compatibility criteria while offering enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5F24-JB is a qualified substitute for the obsolete KB15SKW01-5F24-JB based on the following engineering criteria:

Functional Equivalence: Both components share identical circuit configuration (SPDT), switch function (On-Mom), illumination specifications (LED, Green, 24 VDC), and voltage/temperature operating parameters. Electrical performance is directly compatible.

Performance Enhancement: The YB15SKW01-5F24-JB provides superior mechanical and electrical life ratings (1,000,000 and 100,000 cycles respectively versus 100,000 and 50,000 cycles), with higher current capacity (3A versus 1A). These enhancements do not compromise compatibility and provide margin for system reliability.

Active Product Status: The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Implementation Considerations: Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. Termination style changes from Solder Lug to Solder with Quick Connect option, necessitating wiring harness adaptation. These are mechanical and assembly-level changes that do not affect electrical functionality.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5F24-JB directly replace the KB15SKW01-5F24-JB without any modifications?

A: Electrical functionality is directly compatible. However, mechanical modifications are required: the panel cutout must be enlarged from 12.30mm to 16.00mm diameter, and the termination connection method must be adapted from Solder Lug to the Quick Connect termination style of the substitute part.

Q: What is the significance of the higher current rating (3A versus 1A) on the substitute part?

A: The substitute part is rated for higher current capacity, which provides additional safety margin in the circuit. This does not create incompatibility; the substitute can safely handle applications designed for the lower 1A rating.

Q: Are the mechanical and electrical life improvements on the substitute part relevant to substitution decisions?

A: Yes. The YB15SKW01-5F24-JB offers 10x higher mechanical life (1,000,000 versus 100,000 cycles) and 2x higher electrical life (100,000 versus 50,000 cycles). These improvements enhance system reliability and component longevity without introducing compatibility issues.

Q: What panel modifications are necessary for the larger cutout diameter?

A: The panel cutout must be enlarged from 12.30mm to 16.00mm diameter. This requires mechanical modification to the panel assembly. The front-mount installation orientation remains identical.

Q: How does the termination style difference affect installation?

A: The original part uses Solder Lug termination, while the substitute offers Solder with Quick Connect (0.110" / 2.8mm) options. Wiring harness connectors must be adapted accordingly. Both termination methods provide equivalent electrical connection reliability.

Q: Is the substitute part RoHS and REACH compliant?

A: The original KB15SKW01-5F24-JB is ROHS3 Compliant and REACH Unaffected. Compliance information for the YB15SKW01-5F24-JB should be verified with the manufacturer for current regulatory status.
