Key Parameters

Substitute Part Grouping Explanation

The YB26SKW01-5C-JC qualifies as a substitute based on the following matching parameters:

Matching Electrical Characteristics:

• DPDT circuit configuration
• On-On switch function
• 125V AC voltage rating
• 30V DC voltage rating
• Red LED illumination at 1.9VDC nominal

Matching Mechanical Characteristics:

• Panel mount, front installation
• Square button actuator with no marking
• Clear actuator with red filter/diffuser
• Operating temperature range: -25°C to 50°C

Compliance & Regulatory:

• ROHS3 compliant
• REACH unaffected
• ECCN: EAR99
• HTSUS: 8536.50.9033

The primary difference is the current rating increase from 1A to 3A, which represents an enhancement rather than a limitation. The substitute part also features improved mechanical life (200,000 cycles vs. 100,000 cycles) and electrical life (100,000 cycles vs. 50,000 cycles), along with an active product status versus obsolete.

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01-5C-JC is suitable as a substitute for the KB26SKW01-5C-JC based on electrical and mechanical compatibility. The substitute maintains identical voltage ratings, circuit configuration, and illumination specifications while providing enhanced current capacity and operational life ratings.

The active product status of the YB26SKW01-5C-JC ensures ongoing availability and supply chain continuity, addressing the obsolescence of the original KB26SKW01-5C-JC. Both components maintain ROHS3 compliance and identical regulatory classifications.

Physical integration requires consideration of the panel cutout diameter difference: the substitute requires a 16.00mm circular cutout versus the original 12.30mm specification. Termination style differs between solder lug (original) and solder with quick connect options (substitute), necessitating circuit board layout and connector compatibility verification.

Frequently Asked Questions (FAQ)

Q: Can YB26SKW01-5C-JC directly replace KB26SKW01-5C-JC in existing applications?

A: Electrical substitution is valid based on matching DPDT configuration, voltage ratings, and illumination specifications. Physical integration requires panel cutout modification from 12.30mm to 16.00mm diameter and termination style adaptation from solder lug to solder/quick connect configuration.

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

A: The higher current rating of the substitute part represents an enhancement that maintains backward compatibility for applications operating at or below 1A. Applications requiring higher current capacity benefit from the increased rating without electrical parameter compromise.

Q: Are there compliance differences between the two parts?

A: Both components maintain identical ROHS3 compliance, REACH unaffected status, and regulatory classifications (ECCN: EAR99, HTSUS: 8536.50.9033). No compliance barriers exist for substitution.

Q: What mechanical life improvement does the substitute provide?

A: The YB26SKW01-5C-JC offers 200,000 mechanical cycles versus 100,000 cycles for the KB26SKW01-5C-JC, representing a 100% increase in mechanical durability. Electrical life similarly increases from 50,000 to 100,000 cycles.

Q: How does the panel cutout size difference affect installation?

A: The substitute requires a larger circular cutout (16.00mm versus 12.30mm diameter). Existing panel installations designed for the original part require mechanical modification to accommodate the larger diameter, or alternative mounting solutions must be evaluated.

Q: What termination considerations apply to the substitute?

A: The substitute offers dual termination options (solder and quick connect 0.110" / 2.8mm) compared to the original solder lug configuration. Circuit board design and connector compatibility must be verified prior to implementation.
