KB15NKG01 Equivalent & Substitute Parts

Part Overview

The KB15NKG01 is a pushbutton switch manufactured by NKK Switches, configured as a Standard Panel Mount, Snap-In SPDT (Single Pole Double Throw) switch with On-Mom (momentary) function. This component is rated for 0.4VA at 28V AC/DC and features a plunger actuator with solder lug termination. The KB15NKG01 is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15NKG01 is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

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

Mechanical Parameters (Must Match):

• Mounting type: Panel Mount, Snap-In
• Actuator type: Plunger for Cap
• Operating temperature range: -25°C to 70°C or wider

Compliance Parameters:

• RoHS3 compliance required
• REACH unaffected status

The YB15NKG01 meets all electrical and mechanical substitution criteria. Differences in termination style, panel cutout diameter, mechanical life rating, and product status do not preclude substitution when the electrical and mechanical core parameters align.

Parameter Comparison

Engineering Selection Recommendations

The YB15NKG01 is a qualified substitute for the KB15NKG01 based on matching electrical specifications (SPDT circuit, On-Mom function, 0.4VA at 28V AC/DC) and mechanical compatibility (Panel Mount, Snap-In, plunger actuator, identical operating temperature range). Both components maintain ROHS3 compliance and REACH unaffected status.

The YB15NKG01 offers the advantage of active product status, ensuring continued availability and supply chain stability. The extended mechanical life rating (1,000,000 cycles versus 100,000 cycles) provides enhanced durability for applications requiring extended operational cycles.

Design integration requires consideration of termination style differences: the KB15NKG01 uses solder lug termination, while the YB15NKG01 provides solder and quick connect (0.110" / 2.8mm) termination options. Additionally, the panel cutout diameter differs (12.30mm versus 16.00mm), necessitating mechanical panel redesign or adapter consideration for direct replacement in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the YB15NKG01 directly replace the KB15NKG01 in existing designs?

A: Electrical and functional compatibility is confirmed. Mechanical integration requires evaluation of panel cutout diameter differences (12.30mm versus 16.00mm) and termination style compatibility (solder lug versus solder/quick connect options).

Q: What are the critical parameters for substitution eligibility?

A: Substitution requires matching SPDT circuit configuration, On-Mom switch function, 0.4VA current rating, 28V AC/DC voltage rating, Panel Mount Snap-In mounting type, plunger actuator type, and -25°C to 70°C operating temperature range. RoHS3 compliance is mandatory.

Q: Why is the panel cutout diameter different between these parts?

A: The KB15NKG01 and YB15NKG01 are distinct product series within the NKK Switches portfolio. The YB series incorporates a larger panel cutout diameter (16.00mm) as part of its mechanical design specification.

Q: Does the difference in mechanical life rating affect substitution suitability?

A: The YB15NKG01 mechanical life rating (1,000,000 cycles) exceeds the KB15NKG01 specification (100,000 cycles). This represents an enhancement rather than a limitation for substitution purposes.

Q: Are there compliance or certification differences between these parts?

A: Both components maintain identical RoHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution.

Q: What is the significance of the KB15NKG01 obsolete status?

A: Obsolete status indicates discontinued manufacturing. The YB15NKG01 active status ensures ongoing availability and supply chain continuity for equivalent functionality.
