Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16SKW01-5C12-JB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Voltage rating: 125V AC minimum, 30V DC minimum
• Mounting type: Panel Mount, Front
• Illumination: LED, Red color
• Illumination voltage: 12VDC nominal
• Operating temperature range: -25°C to 50°C minimum
• Actuator type: Square, Button
• Termination compatibility with solder lug applications

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher current ratings are compatible for lower-current applications)
• Mechanical life: May exceed 100,000 cycles
• Electrical life: May exceed 50,000 cycles
• Panel cutout diameter: Variation acceptable if mechanical integration is verified
• Termination style: Quick Connect acceptable as alternative to Solder Lug with appropriate adapter consideration

The YB16SKW01-5C12-JB qualifies as a substitute based on matching all mandatory parameters while offering enhanced performance specifications in current rating, mechanical life, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-5C12-JB serves as a direct functional substitute for the obsolete KB16SKW01-5C12-JB. Both components maintain identical electrical specifications for voltage and circuit configuration, with the substitute offering superior performance in current capacity (3A versus 1A) and operational longevity (200,000 mechanical cycles and 100,000 electrical cycles versus 100,000 and 50,000 respectively).

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility. The substitute's active product status provides supply chain continuity and long-term availability advantages over the obsolete original part.

Termination style differences (Solder Lug on original versus Solder and Quick Connect on substitute) require mechanical integration assessment. The substitute's larger panel cutout diameter (16.00mm versus 12.30mm) necessitates panel modification evaluation for direct replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5C12-JB replace the KB16SKW01-5C12-JB in existing designs?

A: Yes, the YB16SKW01-5C12-JB is functionally compatible. Both components share identical SPDT circuit configuration, On-On switch function, 125V AC and 30V DC voltage ratings, and 12VDC LED illumination specifications. Panel cutout diameter and termination style differences require mechanical integration verification.

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

A: The substitute offers higher current capacity (3A versus 1A), extended mechanical life (200,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles). Panel cutout diameter increases from 12.30mm to 16.00mm. Termination options expand from Solder Lug to include Quick Connect alternatives.

Q: Are both parts RoHS compliant?

A: Yes, both KB16SKW01-5C12-JB and YB16SKW01-5C12-JB are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Does the larger panel cutout on the substitute affect compatibility?

A: The YB16SKW01-5C12-JB requires a 16.00mm circular panel cutout compared to 12.30mm for the original part. Existing panel installations designed for the KB16SKW01-5C12-JB require mechanical modification to accommodate the larger diameter.

Q: What termination options are available on the substitute?

A: The YB16SKW01-5C12-JB offers both Solder and Quick Connect 0.110" (2.8mm) termination options, providing flexibility beyond the Solder Lug termination of the original part.

Q: Is the substitute part currently available?

A: Yes, the YB16SKW01-5C12-JB maintains active product status with 968 pieces in stock, ensuring supply continuity compared to the obsolete KB16SKW01-5C12-JB.
