Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15CKW01-05-JC is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT (maintained)
• Mounting type: Panel Mount, Front (maintained)
• Switch function: On-Mom (maintained)
• Actuator type: Round, Button (maintained)
• Color - Actuator/Cap: Clear with Red Filter/Diffuser (maintained)
• Operating temperature range: -25°C to 50°C (maintained)
• Voltage rating - AC: 125V (maintained)
• Voltage rating - DC: 30V (maintained)
• RoHS compliance: ROHS3 Compliant (maintained)

Parameters Permitting Variation:

• Current rating: May increase from 1A to 3A (backward compatible for lower-current applications)
• Illumination type: May change from Incandescent to LED (functional equivalent with different electrical characteristics)
• Illumination voltage: May change from 5VAC to 5VDC (different power source requirement)
• Mechanical life: May increase from 100,000 to 1,000,000 cycles (enhanced durability)
• Electrical life: May increase from 50,000 to 100,000 cycles (enhanced durability)
• Panel cutout diameter: May increase from 12.30mm to 16.00mm (requires panel modification)
• Termination style: May change from Solder Lug to Solder with Quick Connect (different connection method)

Engineering Selection Recommendations

The YB15CKW01-5C05-JC serves as a direct functional substitute for the obsolete KB15CKW01-05-JC based on the following engineering criteria:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Electrical Compatibility: The substitute maintains identical voltage ratings (125V AC, 30V DC) and circuit configuration (SPDT), supporting direct functional replacement in existing circuit designs. The increased current rating (3A versus 1A) provides enhanced capacity for applications operating at or below the original 1A specification.

Mechanical and Operational Durability: The substitute demonstrates superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), extending component service intervals and reducing maintenance frequency.

Active Product Status: The substitute maintains active product status with documented inventory availability, ensuring long-term supply chain continuity compared to the obsolete main part.

Implementation Considerations: Panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification for installation. Illumination changes from incandescent (5VAC) to LED (5VDC), necessitating power supply circuit adjustment. Termination style changes from solder lug to solder with quick connect, requiring connection method modification.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKW01-5C05-JC directly replace the KB15CKW01-05-JC without circuit modification?

A: The substitute maintains identical voltage ratings, circuit configuration, and switch function. However, illumination voltage changes from 5VAC to 5VDC, requiring power supply circuit adjustment. Panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification. Termination style changes from solder lug to solder with quick connect, requiring connection method modification.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Circuit configuration (SPDT), voltage ratings (125V AC, 30V DC), switch function (On-Mom), and mounting type (Panel Mount, Front) must remain identical. Current rating may increase from 1A to 3A. Illumination type and voltage may change while maintaining red color output.

Q: Is the substitute suitable for applications requiring the original 1A current rating?

A: Yes. The substitute's 3A current rating is backward compatible with applications designed for 1A operation. The higher rating provides additional capacity margin without affecting performance in lower-current applications.

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

A: LED illumination operates at 5VDC instead of 5VAC, requiring power supply circuit modification. LED provides extended operational life and reduced power consumption compared to incandescent technology.

Q: Does the panel cutout diameter change affect mechanical compatibility?

A: The increase from 12.30mm to 16.00mm requires panel modification. Existing panel cutouts designed for the original part will not accommodate the substitute without enlargement.

Q: Are both components suitable for the same operating temperature range?

A: Yes. Both components operate across the identical temperature range of -25°C to 50°C, ensuring thermal compatibility in equivalent environmental conditions.

Q: What is the significance of the product status difference?

A: The main part (KB15CKW01-05-JC) is classified as obsolete, indicating discontinued manufacturing and limited future availability. The substitute (YB15CKW01-5C05-JC) maintains active status with ongoing production and documented inventory, ensuring supply chain continuity.
