Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-5C24-AB is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Mounting type must be Panel Mount, Front
• Actuator type must be Square Button
• Illumination type must be LED, Red
• Voltage ratings must support AC 125 V and DC 30 V minimum
• Operating temperature range must encompass -25°C to 50°C
• RoHS3 compliance required
• Moisture Sensitivity Level must be 1 (Unlimited)

The YB15SKW01-5C24-AB meets all substitution criteria. While this part exhibits enhanced electrical and mechanical performance characteristics, it maintains functional compatibility with the original specification requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C24-AB is a direct functional substitute for the obsolete KB15SKW01-5C24-AB. Both components are manufactured by NKK Switches and maintain identical compliance certifications (ROHS3, EAR99 classification, HTSUS code 8536.50.9031).

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. The YB series demonstrates enhanced performance metrics, including higher current rating (3A versus 1A), extended mechanical life (1,000,000 versus 100,000 cycles), and doubled electrical life (100,000 versus 50,000 cycles).

Physical integration requires consideration of panel cutout dimensions: the YB15SKW01-5C24-AB requires a 16.00mm diameter circular opening compared to the original 12.30mm specification. Termination style differs between solder lug (original) and solder with quick connect options (substitute). Illumination voltage operates at 1.9 VDC for the substitute versus 24 VDC for the original part.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C24-AB directly replace the KB15SKW01-5C24-AB without circuit modifications?

A: The substitute maintains identical circuit configuration (SPDT), voltage ratings (AC 125V, DC 30V), and switch function (On-Momentary). However, the illumination voltage differs (1.9 VDC versus 24 VDC), requiring verification of the LED drive circuit in your application. Termination style also differs, necessitating connection method adjustment.

Q: What are the physical installation considerations?

A: The panel cutout diameter increases from 12.30mm to 16.00mm. Existing panel openings must be enlarged to accommodate the substitute part. Termination connections change from solder lug to solder with quick connect options, requiring corresponding PCB or wiring modifications.

Q: Are both parts RoHS compliant?

A: Yes, both the KB15SKW01-5C24-AB and YB15SKW01-5C24-AB are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the availability difference between these parts?

A: The KB15SKW01-5C24-AB is classified as obsolete. The YB15SKW01-5C24-AB is in active production status, providing assured long-term component availability.

Q: How do the performance specifications compare?

A: The substitute part offers superior performance: current rating increases from 1A to 3A, mechanical life extends from 100,000 to 1,000,000 cycles, and electrical life doubles from 50,000 to 100,000 cycles. Both maintain identical operating temperature range (-25°C to 50°C).
