Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15RKW01-5C-JB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Front
• Illumination: LED, Red, 1.9VDC nominal
• Operating temperature range: -25°C to 50°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: Equal to or greater than 1A
• Panel cutout diameter: Mechanical accommodation required
• Termination style: Functional equivalence acceptable
• Mechanical/Electrical life: Equal to or greater than specified values

The YB15RKW01-5C-JB meets all mandatory compatibility parameters while exceeding performance specifications in current rating (3A vs. 1A), mechanical life (1,000,000 vs. 100,000 cycles), and electrical life (100,000 vs. 50,000 cycles). The substitute maintains identical voltage ratings, circuit configuration, illumination characteristics, and temperature operating range.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01-5C-JB is a direct functional substitute for the obsolete KB15RKW01-5C-JB. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The substitute part carries active product status, ensuring long-term availability and supply chain continuity. The YB15RKW01-5C-JB exceeds the electrical and mechanical performance specifications of the original part, providing enhanced reliability margins for applications requiring extended operational life or higher switching frequency.

Physical integration requires verification of panel cutout accommodation, as the substitute features a 16.00mm circular cutout diameter compared to the original 12.30mm specification. Termination style differences (Quick Connect 0.110" vs. Solder Lug) necessitate circuit board layout evaluation for compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKW01-5C-JB directly replace the KB15RKW01-5C-JB in existing designs?

A: Electrical and functional compatibility is confirmed. Physical integration requires panel cutout diameter verification (16.00mm vs. 12.30mm) and termination style accommodation (Quick Connect vs. Solder Lug). Circuit board redesign may be necessary.

Q: What are the key differences between these two parts?

A: The substitute provides higher current capacity (3A vs. 1A), extended mechanical life (1,000,000 vs. 100,000 cycles), and improved electrical life (100,000 vs. 50,000 cycles). Voltage ratings, circuit configuration, illumination characteristics, and operating temperature range remain identical.

Q: Are both parts RoHS compliant?

A: Both KB15RKW01-5C-JB and YB15RKW01-5C-JB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the significance of the product status difference?

A: The KB15RKW01-5C-JB is classified as obsolete, indicating discontinued manufacturing and limited availability. The YB15RKW01-5C-JB maintains active status, ensuring reliable supply chain access and manufacturer support.

Q: Does the substitute require different illumination voltage supply?

A: No. Both parts operate at identical illumination voltage (1.9VDC nominal), requiring no changes to LED drive circuitry.

Q: What panel cutout modifications are required for the substitute?

A: The YB15RKW01-5C-JB requires a 16.00mm circular cutout compared to the original 12.30mm specification. Panel drilling or modification may be necessary depending on existing mechanical design.
