Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKW01-12-JC is determined by the following critical parameters:

Core Functional Requirements:

• Circuit configuration must remain SPDT
• Switch function must be On-Mom (momentary)
• Mounting type must be Panel Mount, Front
• Actuator type must be Round, Button with no marking
• Color must be Clear with Red Filter/Diffuser

Electrical Compatibility Parameters:

• Voltage rating must support minimum 125V AC and 30V DC
• Current rating must meet or exceed 1A
• Operating temperature range must encompass -25°C ~ 50°C

Mechanical & Physical Parameters:

• Panel cutout diameter must accommodate the original 12.30mm specification or be compatible with existing panel installations
• Termination style must be compatible with solder lug connections

Compliance & Regulatory:

• RoHS3 compliance required
• REACH unaffected status required

The substitute part YB15CKW01-5C12-JC meets these criteria while offering enhanced performance characteristics in mechanical and electrical life cycles.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-5C12-JC serves as a direct functional substitute for the obsolete KB15CKW01-12-JC. Both components maintain identical circuit configuration, voltage ratings, and mounting specifications required for panel-integrated applications.

Substitution Basis:

The substitute part is qualified based on:

• Active product status, ensuring long-term availability and supply chain continuity
• ROHS3 compliance alignment with the original component
• REACH unaffected status, maintaining regulatory equivalence
• Enhanced electrical and mechanical life ratings, providing superior reliability in equivalent applications
• Identical core electrical parameters (125V AC, 30V DC) and mounting architecture

Notable Differences:

The substitute incorporates LED illumination at 12 VDC in place of incandescent illumination at 12 VAC, and features increased current capacity (3A versus 1A) and panel cutout diameter (16.00mm versus 12.30mm). These differences represent performance enhancements and do not preclude substitution in applications where the original component was specified, provided panel cutout modifications are feasible or the larger diameter is accommodated by existing panel geometry.

Frequently Asked Questions (FAQ)

Q: Can YB15CKW01-5C12-JC directly replace KB15CKW01-12-JC without modifications?

A: Functional substitution is supported. The core electrical parameters and circuit configuration are identical. Panel cutout diameter differs (16.00mm versus 12.30mm), requiring panel modification or verification that the larger diameter is compatible with existing installation geometry.

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

A: The illumination type changes from incandescent (12 VAC) to LED (12 VDC). This requires verification that the control circuit supplies 12 VDC rather than 12 VAC for the illumination function. LED illumination provides extended operational life and reduced power consumption compared to incandescent technology.

Q: Are the voltage and current ratings compatible?

A: Yes. The substitute part maintains 125V AC and 30V DC voltage ratings identical to the original. The current rating increases from 1A to 3A, providing additional capacity without reducing compatibility in applications rated for 1A operation.

Q: What compliance certifications apply to both parts?

A: Both KB15CKW01-12-JC and YB15CKW01-5C12-JC are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for electronic component deployment.

Q: Why is the substitute part classified as active while the original is obsolete?

A: Product status reflects manufacturer support and availability. The active status of YB15CKW01-5C12-JC ensures continued supply, technical support, and compliance with current manufacturing standards, making it suitable for new designs and ongoing maintenance applications.

Q: How do mechanical and electrical life cycles compare?

A: The substitute part provides extended mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), indicating enhanced durability and longer operational intervals between maintenance or replacement.
