KB15KKG01 Equivalent & Substitute Parts

Part Overview

The KB15KKG01 is a pushbutton switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-Mom (momentary) function. This component is rated for 0.4VA at 28V AC/DC and features panel mount, snap-in installation with solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and design continuity in applications requiring equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15KKG01 is determined by strict alignment with the following electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (momentary)
• Current rating must support minimum 0.4VA
• Voltage rating must support minimum 28V AC and 28V DC

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Snap-In
• Actuator type must be Plunger for Cap
• Operating temperature range must encompass -25°C to 70°C
• Termination style must be compatible with solder lug connections or equivalent

Compliance Requirements:

• RoHS3 compliance required
• REACH unaffected status required

The YB15KKG01 meets all electrical requirements and maintains mechanical compatibility through equivalent snap-in panel mount design. Differences in panel cutout diameter (16.00mm vs. 12.30mm) and termination options (Quick Connect available) represent design enhancements rather than incompatibilities, as the substitute accommodates the original application parameters while offering extended mechanical life (1,000,000 cycles vs. 100,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB15KKG01 is the qualified substitute for KB15KKG01 applications based on the following engineering criteria:

Electrical Equivalence: Both components maintain identical SPDT circuit configuration, On-Mom switch function, 0.4VA current rating, and 28V AC/DC voltage specifications. Electrical performance in the target application is directly equivalent.

Mechanical Compatibility: Both components feature panel mount, snap-in installation with plunger-type actuators and identical operating temperature ranges (-25°C to 70°C). The YB15KKG01 accommodates the original mechanical interface requirements.

Compliance Status: The YB15KKG01 maintains ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original part.

Product Availability: The YB15KKG01 holds active product status with 1,101 units in stock, ensuring supply continuity for the obsolete KB15KKG01.

Enhanced Performance: The YB15KKG01 provides extended mechanical life (1,000,000 cycles vs. 100,000 cycles), representing a performance improvement over the original specification.

Installation Consideration: The larger panel cutout diameter of the YB15KKG01 (16.00mm vs. 12.30mm) requires panel modification for direct replacement in existing assemblies. Termination flexibility (solder lug or quick connect options) accommodates various circuit board configurations.

Frequently Asked Questions (FAQ)

Q: Can YB15KKG01 directly replace KB15KKG01 without circuit modification?

A: Electrical and functional compatibility is complete. The YB15KKG01 maintains identical SPDT circuit configuration, On-Mom function, 0.4VA rating, and 28V voltage specifications. Panel cutout diameter difference (16.00mm vs. 12.30mm) requires mechanical panel modification for physical installation.

Q: What is the difference in termination between KB15KKG01 and YB15KKG01?

A: KB15KKG01 uses solder lug termination exclusively. YB15KKG01 offers both solder and quick connect (0.110" / 2.8mm) termination options, providing installation flexibility while maintaining electrical equivalence.

Q: Does the extended mechanical life of YB15KKG01 affect electrical performance?

A: No. The 1,000,000-cycle mechanical life rating of YB15KKG01 represents enhanced durability compared to the 100,000-cycle rating of KB15KKG01. Electrical specifications, voltage ratings, and current capacity remain identical.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both KB15KKG01 and YB15KKG01 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the primary reason for substitution?

A: KB15KKG01 is obsolete. YB15KKG01 is an active product from the same manufacturer with equivalent electrical specifications and enhanced mechanical performance, ensuring supply continuity and long-term availability.

Q: Can YB15KKG01 be used in applications originally designed for KB15KKG01?

A: Yes, provided panel cutout dimensions are modified to accommodate the 16.00mm diameter requirement. All electrical and functional parameters are equivalent or superior.
