Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16MKW01-5F-JB is determined by the following critical parameters:

• Circuit configuration (SPDT required)
• Switch function (On-On operation)
• Voltage ratings (AC 125V minimum, DC 30V minimum)
• Mounting type (Panel Mount, Snap-In)
• Illumination type and color (LED, Green)
• Operating temperature range (-25°C ~ 50°C)
• Regulatory compliance (RoHS3, REACH status)

The YB16MKW01-5F-JB meets these core substitution criteria. However, differences exist in current rating, mechanical/electrical life, panel cutout dimensions, and termination style. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB16MKW01-5F-JB is functionally equivalent to the KB16MKW01-5F-JB for applications requiring SPDT illuminated pushbutton switching at 125V AC / 30V DC with LED green illumination. The substitute part is currently in active production status, addressing the obsolescence of the original component.

Key considerations for selection:

• The YB16MKW01-5F-JB provides higher current capacity (3A vs. 1A), which is compatible with applications designed for 1A operation.
• Mechanical and electrical life ratings are doubled in the substitute part, providing extended operational durability.
• Panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification or redesign.
• Termination style differs (Solder Lug vs. Solder/Quick Connect), necessitating circuit board layout adjustment.
• Illumination voltage nominal specification differs slightly (2.1V vs. 2V), remaining within typical LED operating tolerances.

Selection of the YB16MKW01-5F-JB is appropriate when panel cutout modifications and termination style changes are feasible within the design constraints.

Frequently Asked Questions (FAQ)

Q: Can the YB16MKW01-5F-JB directly replace the KB16MKW01-5F-JB without modifications?

A: Direct replacement is not possible without panel modifications. The YB16MKW01-5F-JB requires a 16.00mm diameter cutout compared to the 12.30mm cutout of the original part. Additionally, termination style differs, requiring circuit board layout changes.

Q: Are the voltage and current ratings compatible?

A: Yes. The YB16MKW01-5F-JB maintains identical AC voltage (125V) and DC voltage (30V) ratings. The increased current rating (3A vs. 1A) is backward-compatible with applications designed for 1A operation.

Q: What is the impact of the different illumination voltage specifications?

A: The nominal illumination voltage differs by 0.1V (2.1V vs. 2V). This variation is within standard LED operating tolerances and does not affect functional compatibility in typical circuit designs.

Q: Does the substitute part have the same mechanical durability?

A: The YB16MKW01-5F-JB provides superior mechanical and electrical life ratings (200,000 and 100,000 cycles respectively, compared to 100,000 and 50,000 cycles). This represents an improvement over the original specification.

Q: What are the termination style implications?

A: The KB16MKW01-5F-JB uses Solder Lug termination, while the YB16MKW01-5F-JB offers Solder and Quick Connect (0.110" / 2.8mm) options. Circuit board design must accommodate the different connection method.
