Key Parameters

Substitute Part Grouping Explanation

The YB15SKW01-5C-JC qualifies as a substitute for the KB15SKW01B-5C-JC based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Voltage rating - AC: 125V
• Voltage rating - DC: 30V
• Actuator type: Square Button
• Illumination type and color: LED, Red
• Illumination voltage: 1.9V DC
• Operating temperature range: -25°C to 50°C
• Mounting type: Panel Mount, Front
• RoHS compliance: ROHS3 Compliant

Differing Parameters:

• Current rating: 3A (versus 1A in original)
• Panel cutout diameter: 16.00mm (versus 12.30mm in original)
• Mechanical life: 1,000,000 cycles (versus 100,000 cycles)
• Electrical life: 100,000 cycles (versus 50,000 cycles)
• Termination style: Solder, Quick Connect - 0.110" (versus Solder Lug)
• Product status: Active (versus Obsolete)

The substitute part provides enhanced electrical and mechanical durability with higher current capacity and cycle life ratings, while maintaining core functional compatibility in voltage, circuit topology, and illumination specifications.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C-JC is available as an active product from NKK Switches, whereas the KB15SKW01B-5C-JC is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Selection of the substitute part requires consideration of mechanical integration constraints. The panel cutout diameter increases from 12.30mm to 16.00mm, necessitating panel modification or adapter solutions for direct replacement in existing enclosures. The termination style transition from Solder Lug to Solder with Quick Connect - 0.110" requires corresponding wiring harness or PCB layout adjustments.

The enhanced current rating (3A versus 1A) and extended cycle life ratings (1,000,000 mechanical cycles and 100,000 electrical cycles versus 100,000 and 50,000 respectively) provide improved performance margins for applications within the original voltage and functional specifications.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C-JC directly replace the KB15SKW01B-5C-JC without panel modification?

A: No. The panel cutout diameter differs (16.00mm versus 12.30mm). Panel drilling or mechanical adaptation is required for installation.

Q: Are the electrical specifications compatible between these parts?

A: Yes, for applications operating at or below 1A. Both parts maintain identical voltage ratings (125V AC, 30V DC), circuit configuration (SPDT), and illumination specifications (LED, Red, 1.9V DC). The substitute part supports higher current loads (3A) but can operate safely at the original 1A specification.

Q: What is the impact of the different termination styles?

A: The original uses Solder Lug termination; the substitute uses Solder with Quick Connect - 0.110" (2.8mm). Wiring connections must be adapted accordingly. Quick Connect terminals require compatible female connectors; Solder Lug connections require direct soldering.

Q: Do both parts meet current regulatory compliance?

A: Yes. Both the KB15SKW01B-5C-JC and YB15SKW01-5C-JC are ROHS3 compliant and REACH unaffected.

Q: What are the advantages of the substitute part?

A: The YB15SKW01-5C-JC offers extended mechanical life (1,000,000 cycles versus 100,000), increased electrical life (100,000 cycles versus 50,000), higher current capacity (3A versus 1A), and active product status with ongoing manufacturer support.

Q: Is the actuator type identical between both parts?

A: Yes. Both parts feature a square button actuator with no marking and clear red filter/diffuser coloring.
