Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15SKW01-05-JB is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Voltage ratings must meet or exceed 125V AC and 30V DC
• Current rating must support the application load (minimum 1A)
• Illumination voltage compatibility (5V nominal)

Mechanical Compatibility Requirements:

• Panel mount, front-facing installation capability
• Actuator type: Square button configuration
• Operating temperature range: -25°C to 50°C minimum
• Termination style compatibility with existing wiring

Regulatory & Compliance Requirements:

• ROHS3 compliance
• REACH unaffected status
• ECCN EAR99 classification

The substitute part YB15SKW01-5F05-JB meets these criteria while offering enhanced performance characteristics in mechanical and electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5F05-JB serves as a direct functional substitute for the obsolete KB15SKW01-05-JB. Both components maintain identical SPDT circuit configuration, voltage ratings (125V AC / 30V DC), and panel-mount mechanical interface. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

Current Rating: The substitute provides 3A capacity versus the original 1A rating. This higher current capability is compatible with applications designed for 1A operation and provides additional design margin for future load requirements.

Illumination Technology: The substitute employs LED green illumination at 5 VDC, replacing the incandescent white illumination at 5 VAC. LED technology offers extended operational life and reduced power consumption compared to incandescent sources.

Panel Cutout Dimensions: The substitute requires a 16.00mm diameter cutout versus the original 12.30mm. Panel modifications are necessary for mechanical installation.

Termination Style: The substitute features solder and quick-connect 0.110" (2.8mm) termination, differing from the original solder lug configuration. Wiring harness adaptation may be required.

Lifecycle Performance: The substitute demonstrates superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), supporting extended operational intervals.

Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5F05-JB directly replace the KB15SKW01-05-JB without modifications?

A: Electrical and functional compatibility is confirmed. However, mechanical installation requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination style differences necessitate wiring harness reconfiguration from solder lug to solder/quick-connect 0.110" terminals.

Q: What are the implications of the illumination technology change from incandescent to LED?

A: The illumination voltage changes from 5 VAC to 5 VDC. Circuit design modifications are required to supply DC voltage instead of AC voltage to the illumination circuit. LED green illumination replaces white incandescent illumination, affecting visual indication characteristics.

Q: Is the higher current rating of the substitute (3A versus 1A) compatible with the original application?

A: Yes. The substitute's 3A rating exceeds the original 1A requirement and is fully compatible with applications designed for 1A operation. The higher rating provides additional design margin without compromising functionality.

Q: Are both components compliant with current regulatory standards?

A: Both the KB15SKW01-05-JB and YB15SKW01-5F05-JB maintain ROHS3 compliance and REACH unaffected status. The substitute's active product status ensures ongoing compliance with evolving regulatory requirements.

Q: What is the significance of the mechanical and electrical life improvements in the substitute?

A: The substitute provides 10x improvement in mechanical life (1,000,000 versus 100,000 cycles) and 2x improvement in electrical life (100,000 versus 50,000 cycles). These enhancements support extended maintenance intervals and improved system reliability.

Q: Are there packaging differences between the main part and substitute?

A: The main part is supplied in standard packaging, while the substitute is supplied in bulk packaging. This difference affects procurement and inventory management but does not impact component functionality or performance.
