Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16NKG01 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (0.4VA AC/DC minimum)
• Voltage rating (28V AC/DC minimum)
• Mounting type (Panel Mount, Snap-In)
• Actuator type (Plunger for Cap)
• Operating temperature range (-25°C to 70°C minimum)

Allowable Variations:

• Termination style may differ (Solder Lug vs. Solder/Quick Connect)
• Mechanical and electrical life ratings may exceed specified minimums
• Panel cutout dimensions may vary within snap-in compatibility constraints
• Product status may transition from obsolete to active

The YB16NKG01 meets all critical matching parameters while offering enhanced mechanical life (200,000 cycles vs. 100,000 cycles) and alternative termination options.

Parameter Comparison

Engineering Selection Recommendations

The YB16NKG01 is a direct functional equivalent to the KB16NKG01 for applications requiring SPDT pushbutton switch functionality at 28V, 0.4VA ratings. Both components maintain ROHS3 compliance and identical electrical specifications.

Selection between these parts depends on application-specific constraints:

KB16NKG01 Selection: Required only when legacy panel cutout dimensions (12.30mm circular) are fixed and cannot be modified. Sourcing is limited due to obsolete status.

YB16NKG01 Selection: Preferred for new designs and retrofit applications where panel cutout modification to 16.00mm circular is feasible. Active product status ensures continued availability. Enhanced mechanical life (200,000 cycles) provides extended service life. Alternative termination options (Quick Connect 0.110") accommodate diverse wiring configurations.

Both components satisfy identical electrical load requirements and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can YB16NKG01 replace KB16NKG01 in existing assemblies?

A: Electrical compatibility is confirmed. Mechanical compatibility depends on panel cutout dimensions. KB16NKG01 requires a 12.30mm circular cutout; YB16NKG01 requires a 16.00mm circular cutout. Panel modification is necessary if cutout dimensions differ.

Q: What are the termination differences between these parts?

A: KB16NKG01 uses Solder Lug termination. YB16NKG01 offers Solder and Quick Connect 0.110" (2.8mm) termination options. Wiring harness compatibility must be verified based on your assembly requirements.

Q: Does the increased mechanical life of YB16NKG01 affect electrical performance?

A: No. Both components maintain identical electrical ratings (0.4VA, 28V AC/DC) and electrical life specifications (100,000 cycles). The 200,000-cycle mechanical life of YB16NKG01 represents enhanced mechanical durability without electrical performance changes.

Q: Are both parts RoHS compliant?

A: Yes. Both KB16NKG01 and YB16NKG01 are ROHS3 compliant.

Q: Why is KB16NKG01 listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. YB16NKG01 remains in active production and is the recommended source for new component procurement.
