Key Parameters

Substitute Part Grouping Explanation

The YB15SKW01-5F05-JB qualifies as a functional substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: Both SPDT
• Switch function: Both On-Mom
• Voltage rating AC: Both 125V
• Voltage rating DC: Both 30V
• Mounting type: Both Panel Mount, Front
• Actuator type: Both Square, Button
• Operating temperature range: Both -25°C to 50°C
• RoHS compliance: Both ROHS3 Compliant

Substitution Feasibility: The YB15SKW01-5F05-JB maintains electrical compatibility through identical circuit topology, voltage ratings, and operating temperature specifications. Both components are manufactured by NKK Switches and share the same fundamental switch architecture. The substitute part is currently in active production status, ensuring availability and ongoing support.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5F05-JB is suitable as a substitute for the obsolete KB15SKW01-01-JB based on electrical parameter alignment and active product status. The substitute maintains SPDT circuit topology, identical voltage ratings, and equivalent operating temperature specifications required for functional replacement.

Design integration requires consideration of the following differences:

Panel Cutout Modification: The substitute requires a 16.00mm diameter panel cutout compared to the original 12.30mm specification. Mechanical redesign of the panel interface is necessary.

Illumination System Redesign: The substitute employs LED green illumination at 5VDC instead of neon white at 110VAC. The illumination circuit requires complete redesign to accommodate the different voltage and technology.

Termination Compatibility: The substitute provides solder and quick connect termination options versus the original solder lug configuration. Wiring harness modification is required.

Performance Enhancement: The substitute provides superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), supporting extended operational reliability.

Both components maintain ROHS3 compliance and are manufactured by NKK Switches, ensuring regulatory consistency and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5F05-JB directly replace the KB15SKW01-01-JB without modifications?

A: No. While the electrical circuit configuration and voltage ratings are compatible, three design modifications are required: panel cutout enlargement from 12.30mm to 16.00mm, illumination circuit redesign for LED 5VDC operation, and termination harness adaptation for quick connect compatibility.

Q: Are the voltage ratings identical between the two parts?

A: Yes. Both components are rated for 125V AC and 30V DC, maintaining electrical compatibility for the switch circuit itself. The illumination subsystem operates at different voltages and requires separate circuit design.

Q: What is the impact of the higher current rating on the substitute part?

A: The YB15SKW01-5F05-JB is rated for 3A compared to the original 1A specification. This higher rating provides design margin and does not create compatibility issues when used in applications requiring 1A or less.

Q: Does the substitute part have better mechanical durability?

A: Yes. The YB15SKW01-5F05-JB provides 1,000,000 mechanical cycles and 100,000 electrical cycles compared to 100,000 and 50,000 cycles respectively for the original part, supporting extended service life in high-cycle applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the KB15SKW01-01-JB and YB15SKW01-5F05-JB are ROHS3 compliant, maintaining regulatory consistency for environmental and hazardous substance requirements.

Q: What is the primary reason for substitution?

A: The KB15SKW01-01-JB is classified as obsolete. The YB15SKW01-5F05-JB is in active production status, ensuring component availability and manufacturer support for new designs and system maintenance.
