Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26SKW01-5C-JB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Panel Mount, Front
• Illumination type: LED, Red
• Illumination voltage: 1.9 VDC
• Operating temperature range: -25°C ~ 50°C
• RoHS compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Current rating: May exceed 1A (higher current capacity is acceptable)
• Electrical life: May exceed 50,000 cycles (higher cycle rating is acceptable)
• Mechanical life: May exceed 100,000 cycles (higher cycle rating is acceptable)
• Termination style: May differ (solder lug vs. quick connect acceptable)
• Panel cutout dimensions: May differ (mechanical accommodation required)

The YB26SKW01-5C-JB qualifies as a substitute based on matching all mandatory parameters while providing enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01-5C-JB is a qualified substitute for the obsolete KB26SKW01-5C-JB based on functional equivalence across all critical electrical and mechanical parameters. The substitute part offers the following advantages:

Product Status: The YB26SKW01-5C-JB maintains Active product status, ensuring continued availability and manufacturer support, whereas the KB26SKW01-5C-JB is classified as Obsolete.

Performance Enhancement: The substitute provides increased current rating (3A vs. 1A) and extended cycle life ratings (200,000 mechanical cycles and 100,000 electrical cycles vs. 100,000 mechanical and 50,000 electrical cycles), delivering improved reliability margins for equivalent applications.

Compliance: Both parts maintain ROHS3 compliance, satisfying regulatory requirements for equivalent implementations.

Termination Consideration: The substitute features dual termination options (Solder and Quick Connect - 0.110" 2.8mm) compared to the main part's solder lug termination. Panel cutout dimensions differ (16.00mm vs. 12.30mm), requiring mechanical accommodation during integration.

Frequently Asked Questions (FAQ)

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

A: Functional substitution is valid based on matching circuit configuration, voltage ratings, and illumination specifications. Physical integration requires verification of panel cutout dimensions (16.00mm for substitute vs. 12.30mm for original) and termination compatibility.

Q: What is the significance of the current rating difference (1A vs. 3A)?

A: The substitute's higher current rating (3A) indicates enhanced electrical capacity. Applications operating at or below 1A are fully compatible. The higher rating provides additional design margin and supports higher-current applications without functional compromise.

Q: Are the cycle life differences important for substitution?

A: The substitute's extended mechanical life (200,000 vs. 100,000 cycles) and electrical life (100,000 vs. 50,000 cycles) represent performance improvements. These enhancements do not prevent substitution; they indicate longer operational durability under equivalent switching conditions.

Q: Does the termination style difference affect substitution eligibility?

A: Termination style differences require circuit board or harness redesign. The substitute offers both solder and quick connect options, providing flexibility. Existing solder lug connections require modification to accommodate the substitute's termination configuration.

Q: Why is product status relevant for component selection?

A: The KB26SKW01-5C-JB's Obsolete status indicates discontinued manufacturing and limited availability. The YB26SKW01-5C-JB's Active status ensures ongoing supply, manufacturer technical support, and long-term design reliability for new implementations or system maintenance.

Q: Are both parts RoHS compliant?

A: Yes, both the KB26SKW01-5C-JB and YB26SKW01-5C-JB maintain ROHS3 compliance, satisfying environmental and regulatory requirements for equivalent applications.
