KB15SKW01-05-GG Equivalent & Substitute Parts

Part Overview

The KB15SKW01-05-GG is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is classified as obsolete, indicating that direct replacements from the original manufacturer may no longer be available through standard distribution channels. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for repair, maintenance, or production applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15SKW01-05-GG is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Switch function must be On-Mom (momentary)
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must support the application load (minimum 1A)

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Square, Button
• Panel cutout dimensions must accommodate the physical installation

Environmental & Operational Requirements:

• Operating temperature range must cover -25°C to 50°C
• RoHS3 compliance required
• Mechanical and electrical life specifications must be documented

The substitute part YB15SKW01-6G-JB meets these criteria while offering enhanced performance characteristics in current rating, mechanical life, and illumination technology.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-6G-JB is a qualified substitute for the obsolete KB15SKW01-05-GG based on the following engineering criteria:

Electrical Equivalence: Both components maintain identical SPDT circuit configuration, On-Mom switch function, and voltage ratings (125V AC / 30V DC). The substitute provides enhanced current capacity (3A versus 1A), which is backward-compatible for applications requiring the original 1A specification.

Mechanical Compatibility: Both switches feature identical mounting type (Panel Mount, Front) and actuator configuration (Square, Button). The panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification for direct replacement.

Compliance & Availability: The substitute part is ROHS3 compliant and carries Active product status, ensuring ongoing availability and supply chain continuity. The original KB15SKW01-05-GG is classified as Obsolete, making the YB15SKW01-6G-JB the appropriate long-term solution.

Performance Enhancement: The substitute offers superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), providing extended operational reliability.

Illumination Technology Transition: The substitute transitions from incandescent illumination (5 VAC) to LED illumination (3.6 VDC), requiring circuit modification for the illumination supply voltage.

Frequently Asked Questions (FAQ)

Q: Can YB15SKW01-6G-JB be used as a direct drop-in replacement for KB15SKW01-05-GG?

A: Electrical and functional compatibility is confirmed. However, mechanical installation requires panel cutout modification due to the increased diameter (16.00mm versus 12.30mm). Illumination supply voltage must be adjusted from 5 VAC to 3.6 VDC.

Q: What are the key differences between these two switches?

A: The primary differences are: current rating (1A to 3A), illumination technology (incandescent to LED), illumination voltage (5 VAC to 3.6 VDC), mechanical life (100,000 to 1,000,000 cycles), electrical life (50,000 to 100,000 cycles), and panel cutout diameter (12.30mm to 16.00mm).

Q: Is the higher current rating of the substitute part a concern?

A: No. The 3A rating of YB15SKW01-6G-JB exceeds the original 1A requirement, providing additional capacity margin. This is backward-compatible for applications designed for 1A operation.

Q: What modifications are required for panel installation?

A: The panel cutout diameter must be enlarged from 12.30mm to 16.00mm to accommodate the substitute switch. Termination connections require adjustment from solder lug to solder/quick connect configuration.

Q: Are both switches RoHS compliant?

A: Yes. Both KB15SKW01-05-GG and YB15SKW01-6G-JB are ROHS3 compliant, meeting environmental and regulatory requirements.

Q: What is the impact of switching from incandescent to LED illumination?

A: LED illumination provides longer operational life, lower power consumption, and reduced heat generation. The illumination supply voltage changes from 5 VAC to 3.6 VDC, requiring circuit redesign for the illumination circuit.
