Engineering Selection Recommendations

The YB26SKW01-5F-JF is a direct functional substitute for the obsolete KB26SKW01-5F-JF. Both components maintain identical electrical specifications for voltage and circuit configuration, with the substitute offering superior performance in current capacity (3A vs. 1A) and operational longevity (200,000 mechanical cycles vs. 100,000).

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system replacements. The substitute's active product status guarantees continued availability and supply chain reliability.

Integration considerations include panel cutout diameter modification (16.00mm vs. 12.30mm) and termination style adaptation (Quick Connect option available in addition to solder connection). These mechanical differences do not affect electrical compatibility and are manageable within standard panel redesign tolerances.

Frequently Asked Questions (FAQ)

Q: Can the YB26SKW01-5F-JF directly replace the KB26SKW01-5F-JF without circuit modifications?

A: Yes. Both components share identical DPDT circuit configuration, On-On switch function, and voltage ratings (125V AC / 30V DC). The 3A current rating of the substitute exceeds the 1A requirement of the original part, maintaining full electrical compatibility.

Q: What mechanical changes are required for substitution?

A: The panel cutout diameter increases from 12.30mm to 16.00mm. Existing panel openings require enlargement to accommodate the substitute. Termination connections differ (solder lug vs. solder/quick connect options), requiring appropriate connector adaptation based on circuit board design.

Q: Are illumination characteristics identical between the two parts?

A: Both components feature LED green illumination with nominal voltages of 2.1 VDC (KB26SKW01-5F-JF) and 2.2 VDC (YB26SKW01-5F-JF). These minor voltage variations fall within standard LED operating tolerances and produce visually equivalent illumination output.

Q: Does the substitute offer any performance advantages?

A: The YB26SKW01-5F-JF provides doubled mechanical life (200,000 vs. 100,000 cycles) and doubled electrical life (100,000 vs. 50,000 cycles), extending component service intervals and system reliability.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the KB26SKW01-5F-JF and YB26SKW01-5F-JF maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and hazardous substance regulations.

Q: What is the availability status of each part?

A: The KB26SKW01-5F-JF is obsolete with limited remaining inventory (799 units). The YB26SKW01-5F-JF is active production with current stock availability (963 units), ensuring long-term supply chain continuity for new applications and system maintenance.
