Key Parameters

Substitute Part Grouping Explanation

The YB26SKW01-5F-JB qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• DPDT circuit configuration and On-On switch function
• Panel mount, front installation orientation
• LED green illumination with compatible voltage operation
• Square button actuator type
• Operating temperature range (-25°C to 50°C)
• ROHS3 compliance and REACH unaffected status
• Identical AC voltage rating (125V)
• Identical DC voltage rating (30V)

Differing Parameters:

• Current rating increased from 1A to 3A
• Mechanical life upgraded from 100,000 to 200,000 cycles
• Electrical life upgraded from 50,000 to 100,000 cycles
• Panel cutout diameter increased from 12.30mm to 16.00mm
• Termination style changed from Solder Lug to Solder with Quick Connect
• Illumination voltage nominal increased from 2.1V to 2.2V
• Product status changed from obsolete to active

The YB26SKW01-5F-JB maintains electrical compatibility within the specified voltage and circuit requirements while providing enhanced current capacity and operational longevity.

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01-5F-JB is an active product with current manufacturing status, whereas the KB26SKW01-5F-JB is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Selection of the YB26SKW01-5F-JB provides enhanced reliability through doubled mechanical and electrical life cycles. The increased current rating of 3A accommodates applications requiring higher switching capacity than the original 1A specification. The active product status ensures continued availability and supply chain stability.

Physical integration requires accommodation of the larger 16.00mm panel cutout diameter compared to the 12.30mm requirement of the original part. Termination compatibility must be evaluated, as the substitute employs Quick Connect 0.110" (2.8mm) terminals in addition to solder connection, whereas the original uses solder lug termination exclusively.

Frequently Asked Questions (FAQ)

Q: Can the YB26SKW01-5F-JB directly replace the KB26SKW01-5F-JB in existing designs?

A: Electrical compatibility is established through matching DPDT circuit configuration, voltage ratings (125V AC, 30V DC), and illumination specifications. Physical integration requires panel cutout modification from 12.30mm to 16.00mm diameter. Termination style differences necessitate connection method evaluation.

Q: What is the significance of the increased current rating from 1A to 3A?

A: The YB26SKW01-5F-JB accommodates higher switching loads. Applications limited to 1A operation remain compatible, as the substitute operates safely at reduced current levels. Applications requiring current capacity between 1A and 3A benefit from the enhanced rating.

Q: Are there compliance differences between these components?

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

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

A: The YB26SKW01-5F-JB provides doubled mechanical life (200,000 cycles versus 100,000 cycles) and doubled electrical life (100,000 cycles versus 50,000 cycles). Applications with extended operational requirements benefit from the enhanced durability specifications.

Q: What packaging considerations apply to the YB26SKW01-5F-JB?

A: The substitute is supplied in tray packaging, whereas the original part number does not specify packaging format. Procurement and handling procedures may require adjustment accordingly.
