Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB25SKW01-01-JC is based on the following allowable parameter variations:

Maintained Parameters (Must Match):

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

Allowable Variations:

• Current rating: May increase from 1A to higher ratings (3A acceptable)
• Illumination type: Neon may be substituted with LED
• Illumination voltage: May differ based on illumination type change
• Mechanical life: May increase from 100,000 to 1,000,000 cycles
• Electrical life: May increase from 50,000 to 100,000 cycles
• Panel cutout diameter: May increase from 12.30mm to 16.00mm (requires panel modification)
• Termination style: May vary (Solder Lug to Solder/Quick Connect)

The substitute part YB25SKW01-5C-JC meets these criteria while offering enhanced electrical performance and extended component life.

Parameter Comparison

Engineering Selection Recommendations

The YB25SKW01-5C-JC serves as a direct functional substitute for the obsolete KB25SKW01-01-JC. Both components maintain identical circuit configuration, switch function, and voltage ratings. The substitute offers enhanced electrical performance with 3A current capacity versus 1A, extended mechanical life (1,000,000 cycles versus 100,000 cycles), and doubled electrical life (100,000 cycles versus 50,000 cycles).

The substitute utilizes LED illumination with 1.9 VDC nominal voltage in place of neon illumination, providing improved energy efficiency and reduced power consumption. Both components maintain ROHS3 compliance and operate across the identical temperature range.

Panel integration requires consideration of the increased cutout diameter: YB25SKW01-5C-JC requires a 16.00mm circular cutout compared to the 12.30mm requirement of the original part. Termination style differs, with the substitute offering solder and quick connect options versus solder lug termination on the original component.

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can YB25SKW01-5C-JC directly replace KB25SKW01-01-JC without circuit modifications?

A: Functional replacement is possible. Both components share identical DPDT circuit configuration, On-Mom switch function, and 125V AC / 30V DC voltage ratings. However, panel cutout diameter differs (16.00mm versus 12.30mm), requiring mechanical panel modification. Termination style also differs; verify compatibility with existing solder lug connections or implement appropriate adapter solutions.

Q: What is the impact of changing from neon to LED illumination?

A: The substitute uses LED illumination at 1.9 VDC nominal voltage versus neon at 110 VAC. This reduces power consumption and heat generation. Illumination circuit design must accommodate the lower voltage requirement. Both provide red indicator color.

Q: Are there any compliance or certification differences?

A: Both components maintain ROHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution.

Q: What are the mechanical life implications of the substitute?

A: YB25SKW01-5C-JC provides 1,000,000 mechanical cycles versus 100,000 cycles for the original part, representing a 10-fold increase in mechanical durability. Electrical life also doubles from 50,000 to 100,000 cycles.

Q: Does the higher current rating of the substitute affect compatibility?

A: The 3A rating of YB25SKW01-5C-JC exceeds the 1A requirement of the original design. Higher current capacity does not create incompatibility; the substitute safely handles applications designed for 1A operation.

Q: What packaging considerations apply to the substitute?

A: YB25SKW01-5C-JC is supplied in bulk packaging, whereas original part packaging specifications were not detailed. Verify packaging requirements for your procurement and assembly processes.
