Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB25SKW01-12-CC is determined by the following critical parameters that must remain compatible:

Circuit configuration must remain DPDT to preserve switching logic in the target application. Switch function must remain On-Mom (momentary operation). Voltage ratings must meet or exceed the original specifications: 125V AC and 30V DC minimum. Current rating must support the application load; higher ratings are acceptable. Mounting type must remain panel mount, front configuration to ensure mechanical fit. Actuator type must remain square button for ergonomic and aesthetic consistency. Illumination color must remain red to maintain visual consistency in control panels. Operating temperature range must encompass the original -25°C to 50°C specification. Termination style compatibility must be verified for circuit board integration.

The YB25SKW01-5C12-JC meets these substitution criteria while offering enhanced performance characteristics in mechanical and electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

The YB25SKW01-5C12-JC is a qualified substitute for the obsolete KB25SKW01-12-CC based on the following engineering criteria:

Functional equivalence is established through identical DPDT circuit configuration and On-Mom switch function. Electrical compatibility is confirmed by matching voltage ratings (125V AC, 30V DC) and exceeding current capacity (3A versus 1A). The substitute component maintains panel-mount front configuration with square button actuator, ensuring mechanical compatibility with existing panel cutouts and user interface requirements.

Product status transition from obsolete to active ensures long-term component availability and supply chain continuity. Both components maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), confirming environmental and regulatory alignment.

The substitute offers enhanced reliability through superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles). LED illumination in the substitute provides extended operational life and reduced power consumption compared to incandescent illumination, though illumination voltage changes from 12 VAC to 12 VDC, requiring verification of the power supply configuration in the target application.

Panel cutout diameter increases from 12.30mm to 16.00mm; mechanical panel modification may be required for installation. Termination style changes from solder lug to solder with quick connect 0.110" (2.8mm), necessitating circuit board connection method evaluation.

Frequently Asked Questions (FAQ)

Q: Can the YB25SKW01-5C12-JC directly replace the KB25SKW01-12-CC without circuit modifications?

A: Functional substitution is possible for DPDT On-Mom switching logic. However, illumination voltage changes from 12 VAC to 12 VDC, requiring verification that the power supply can provide 12 VDC instead of 12 VAC. Termination style changes from solder lug to solder with quick connect, requiring circuit board connection method compatibility assessment.

Q: What is the impact of the panel cutout diameter increase from 12.30mm to 16.00mm?

A: The larger cutout diameter of the substitute component requires mechanical panel modification. Existing panel holes must be enlarged or new panels fabricated to accommodate the 16.00mm diameter requirement.

Q: Does the LED illumination in the substitute affect system performance?

A: LED illumination provides equivalent red visual indication with extended operational life and reduced power consumption. The change from incandescent to LED does not affect switching performance but requires confirmation that the 12 VDC power supply is available in the application.

Q: Are both components RoHS compliant?

A: Yes, both KB25SKW01-12-CC and YB25SKW01-5C12-JC are ROHS3 compliant, confirming environmental and regulatory alignment for applications requiring RoHS certification.

Q: What is the significance of the higher current rating in the substitute?

A: The YB25SKW01-5C12-JC is rated for 3A (AC/DC) compared to 1A (AC/DC) in the original component. This higher rating provides design margin for applications with current loads up to 3A and does not negatively impact lower-current applications.

Q: How do the mechanical and electrical life ratings compare?

A: The substitute component offers significantly extended operational life: mechanical life increases from 100,000 to 1,000,000 cycles, and electrical life increases from 50,000 to 100,000 cycles. This enhancement improves long-term reliability and reduces maintenance requirements.
