Key Parameters

Substitute Part Grouping Explanation

The YB15MKG01 qualifies as a functional substitute for the KB15MKG01 based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-momentary
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 28V (AC/DC)
• Mounting type: Panel Mount, Snap-In
• Actuator type: Plunger for Cap
• Operating temperature range: -25°C to 70°C
• Electrical life: 100,000 Cycles
• RoHS compliance: ROHS3 Compliant

Differing Parameters:

• Termination style: YB15MKG01 uses Solder and Quick Connect - 0.110" (2.8mm) versus KB15MKG01 Solder Lug only
• Panel cutout dimensions: YB15MKG01 requires 16.00mm circular cutout versus KB15MKG01 12.30mm
• Mechanical life: YB15MKG01 rated for 1,000,000 cycles versus KB15MKG01 100,000 cycles
• Product status: YB15MKG01 is Active versus KB15MKG01 Obsolete
• Additional feature: YB15MKG01 includes stainless steel construction

Parameter Comparison

Engineering Selection Recommendations

The YB15MKG01 is the active equivalent for the obsolete KB15MKG01. Both components meet identical electrical specifications (SPDT, 0.4VA, 28V, on-momentary operation) and share the same operating temperature range and RoHS3 compliance status.

Selection of the YB15MKG01 provides additional benefits: active product status ensures ongoing availability, stainless steel construction enhances environmental resistance, and mechanical life rating of 1,000,000 cycles exceeds the original specification by a factor of ten.

Physical integration requires consideration of panel cutout dimensions. The YB15MKG01 requires a 16.00mm circular cutout compared to the KB15MKG01 12.30mm specification. Termination compatibility must be verified: the YB15MKG01 offers both solder and quick connect options, whereas the KB15MKG01 uses solder lug termination exclusively. Circuit board layout and connector availability must be evaluated during design integration.

Frequently Asked Questions (FAQ)

Q: Can the YB15MKG01 directly replace the KB15MKG01 without circuit board modification?

A: Electrical compatibility is confirmed. Physical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination compatibility depends on available connection points: the YB15MKG01 supports both solder and quick connect termination, providing flexibility for existing solder lug designs.

Q: What is the significance of the 1,000,000 cycle mechanical life rating on the YB15MKG01 versus 100,000 cycles on the KB15MKG01?

A: The YB15MKG01 mechanical life specification is ten times higher, indicating extended durability and reduced replacement frequency in high-cycle applications. Both components maintain identical 100,000 cycle electrical life ratings.

Q: Are both components RoHS compliant?

A: Yes. Both the KB15MKG01 and YB15MKG01 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status for these components?

A: The KB15MKG01 (obsolete) has 814 pieces in stock. The YB15MKG01 (active) has 819 pieces in stock, providing immediate availability for new designs and replacement applications.

Q: Does the stainless steel construction of the YB15MKG01 affect electrical performance?

A: No. Stainless steel construction is a material enhancement that does not alter electrical specifications. It provides improved corrosion resistance and environmental durability compared to standard materials.
