KB15RKG01B Equivalent & Substitute Parts

Part Overview

The KB15RKG01B is a pushbutton switch manufactured by NKK Switches, configured as a Standard Panel Mount SPDT (Single Pole Double Throw) switch with On-Momentary function. This component is rated for 0.4VA at 28V AC/DC operation with a plunger actuator and solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15RKG01B is determined by strict alignment of electrical and mechanical parameters. The primary substitute identified is the YB15RKG01, also manufactured by NKK Switches. This substitution is valid based on the following matching criteria:

Electrical Parameters (Mandatory Match):

• Circuit configuration: SPDT
• Switch function: On-Momentary
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 28V AC and 28V DC

Mechanical Parameters (Mandatory Match):

• Mounting type: Panel Mount, Front
• Actuator type: Plunger for Cap
• Operating temperature range: -25°C to 70°C
• RoHS compliance: ROHS3 Compliant

Differences Requiring Evaluation:

• Panel cutout dimensions: KB15RKG01B requires 12.30mm circular cutout; YB15RKG01 requires 16.00mm circular cutout
• Termination style: KB15RKG01B uses Solder Lug; YB15RKG01 uses Solder and Quick Connect 0.110" (2.8mm)
• Mechanical life: KB15RKG01B rated for 100,000 cycles; YB15RKG01 rated for 1,000,000 cycles
• Product status: KB15RKG01B is obsolete; YB15RKG01 is active

Parameter Comparison

Engineering Selection Recommendations

The YB15RKG01 serves as a functional equivalent to the KB15RKG01B for applications requiring SPDT pushbutton switch operation at 28V with 0.4VA current capacity. Both components meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system replacements.

Selection of YB15RKG01 as a substitute requires evaluation of two primary design considerations:

Panel Cutout Compatibility: The YB15RKG01 requires a 16.00mm circular panel cutout compared to the KB15RKG01B's 12.30mm cutout. Panel modification or adapter mounting may be necessary depending on existing mechanical constraints.

Termination Interface: The YB15RKG01 provides dual termination options (Solder and Quick Connect 0.110" 2.8mm) versus the KB15RKG01B's Solder Lug only. Existing solder connections remain compatible; Quick Connect termination offers additional flexibility for future applications.

The YB15RKG01's extended mechanical life rating (1,000,000 cycles versus 100,000 cycles) provides enhanced durability for high-cycle applications without electrical performance degradation.

Frequently Asked Questions (FAQ)

Q: Can YB15RKG01 directly replace KB15RKG01B without modification?

A: Electrical and functional compatibility is confirmed. Mechanical integration requires panel cutout evaluation. The KB15RKG01B's 12.30mm cutout differs from YB15RKG01's 16.00mm requirement. Panel modification or mechanical adapter may be necessary.

Q: Are the electrical ratings identical between KB15RKG01B and YB15RKG01?

A: Yes. Both components are rated for 0.4VA at 28V AC/DC with SPDT configuration and On-Momentary function. Electrical life is specified at 100,000 cycles for both parts.

Q: What is the significance of the different mechanical life ratings?

A: KB15RKG01B is rated for 100,000 mechanical cycles; YB15RKG01 is rated for 1,000,000 cycles. This difference reflects design improvements in the active YB series. For applications within the 100,000-cycle range, both components perform equivalently.

Q: Does the termination style difference affect circuit performance?

A: No. Both Solder Lug (KB15RKG01B) and Solder/Quick Connect (YB15RKG01) termination styles provide equivalent electrical performance. The Quick Connect option on YB15RKG01 offers additional flexibility for future modifications or maintenance procedures.

Q: Why is KB15RKG01B marked as obsolete?

A: Product obsolescence indicates NKK Switches has discontinued manufacturing. YB15RKG01, as an active product, represents the current equivalent offering with enhanced specifications and continued availability.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both KB15RKG01B and YB15RKG01 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.
