Key Parameters

Substitute Part Grouping Explanation

The YB26CKW01-5C12-JC qualifies as a functional substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: Both DPDT On-On switches
• Voltage rating: Both rated 125V AC / 30V DC
• Mounting type: Both panel-mount, front installation
• Actuator type: Both round button configuration
• Illumination color: Both red indication
• Operating temperature: Identical -25°C to +50°C range
• RoHS compliance: Both ROHS3 compliant
• Termination style compatibility: Both solder-based termination methods

Substitution-Enabling Differences: The YB26CKW01-5C12-JC operates at 3A current rating versus the original 1A specification, representing a higher current capacity suitable for applications requiring the original switch's electrical characteristics. The substitute features LED illumination at 12VDC instead of neon at 110VAC, providing modern lighting technology with reduced power consumption. Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. Mechanical and electrical life ratings are doubled (200,000 and 100,000 cycles respectively), indicating enhanced durability. The substitute is active product status versus obsolete, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

Selection between the KB26CKW01-01-JC and YB26CKW01-5C12-JC depends on application-specific requirements and system constraints:

KB26CKW01-01-JC Selection Criteria: Retain this component only if existing inventory is available and the application operates within the original 1A current specification. The obsolete status limits future procurement options. Neon illumination at 110VAC may be required for legacy systems with existing AC power infrastructure. The 12.30mm panel cutout dimension is fixed in existing panel designs.

YB26CKW01-5C12-JC Selection Criteria: Adopt this substitute for new designs or system upgrades. Active product status ensures long-term availability and supply chain continuity. The 3A current rating provides margin for applications at or near the original 1A specification. LED illumination reduces power consumption and offers modern reliability. ROHS3 compliance and doubled mechanical/electrical life ratings support extended system lifecycles. Panel cutout modification to 16.00mm diameter is required during installation.

Both components maintain identical voltage ratings (125V AC / 30V DC), DPDT circuit configuration, On-On switching function, and operating temperature range (-25°C to +50°C), confirming functional equivalence for core switching applications.

Frequently Asked Questions (FAQ)

Q: Can the YB26CKW01-5C12-JC directly replace the KB26CKW01-01-JC without modifications?

A: Electrical substitution is direct; mechanical panel modification is required. The panel cutout diameter increases from 12.30mm to 16.00mm, necessitating panel enlargement or adapter ring installation. Illumination voltage changes from 110VAC to 12VDC, requiring circuit modification to the indicator power supply.

Q: What is the impact of the 3A current rating on the YB26CKW01-5C12-JC versus the 1A original specification?

A: The 3A rating represents increased current capacity. Applications operating at or below 1A are fully compatible. The substitute provides design margin and supports higher-current applications within the 125V AC / 30V DC voltage envelope.

Q: Are there compatibility concerns with the LED illumination replacing neon?

A: LED illumination operates at 12VDC versus the original neon at 110VAC. This requires independent power supply modification but offers advantages including reduced power consumption, improved reliability, and extended operational life. The red color indication remains functionally equivalent.

Q: How do the mechanical and electrical life ratings affect component selection?

A: The YB26CKW01-5C12-JC provides doubled mechanical life (200,000 versus 100,000 cycles) and doubled electrical life (100,000 versus 50,000 cycles). This extended durability supports longer system lifecycles and reduces maintenance frequency in high-cycle applications.

Q: What are the packaging and inventory implications?

A: The KB26CKW01-01-JC is obsolete with 1,032 pieces in current inventory. The YB26CKW01-5C12-JC is active product with 896 pieces available. For new designs or long-term system support, the active substitute ensures ongoing procurement availability.

Q: Are both components RoHS compliant?

A: Yes, both the KB26CKW01-01-JC and YB26CKW01-5C12-JC are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
