KB16MKW01-6G-JB Equivalent & Substitute Parts

Part Overview

The KB16MKW01-6G-JB is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with On-On switching function. This component is designed for panel-mount, snap-in applications with a 1A current rating at 125V AC and 30V DC. The switch incorporates blue LED illumination at 3.6VDC nominal and a round button actuator with clear white diffuser. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16MKW01-6G-JB is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Panel Mount, Snap-In)
• Actuator type (Round Button)
• Illumination type and color (LED, Blue)
• Illumination voltage (3.6VDC nominal)
• Termination style (Solder Lug)
• Voltage ratings (125V AC minimum, 30V DC minimum)

Allowable Variations:

• Current rating may exceed 1A (higher current capability is acceptable)
• Operating temperature range may be wider
• Mechanical and electrical life may exceed specified minimums
• Panel cutout diameter may differ if mechanical integration permits
• Product status may transition from obsolete to active

The YB16MKW01-6G-JB meets all mandatory matching parameters while providing enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB16MKW01-6G-JB is a direct functional substitute for the obsolete KB16MKW01-6G-JB. Both components maintain identical electrical circuit topology, voltage specifications, and illumination characteristics. The substitute part offers enhanced performance through increased current capacity (3A versus 1A), extended operating temperature range (-25°C to 70°C versus -25°C to 50°C), and doubled mechanical and electrical life ratings.

The primary design consideration is the panel cutout diameter difference: the substitute requires a 16.00mm circular opening compared to the original 12.30mm specification. This mechanical variation necessitates panel modification or redesign of the mounting interface.

Both parts maintain ROHS3 compliance and equivalent regulatory status (ECCN EAR99, HTSUS 8536.50.9033), ensuring consistent supply chain and compliance requirements. The substitute part carries active product status, providing long-term availability and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the YB16MKW01-6G-JB directly replace the KB16MKW01-6G-JB without circuit modifications?

A: Yes, from an electrical standpoint. Both parts share identical SPDT On-On circuit configuration, voltage ratings (125V AC, 30V DC), and illumination specifications (LED, Blue, 3.6VDC). The higher current rating of the substitute (3A) is backward-compatible with applications designed for 1A operation. Panel cutout diameter modification is required for mechanical installation.

Q: What is the significance of the panel cutout diameter difference?

A: The KB16MKW01-6G-JB requires a 12.30mm circular cutout, while the YB16MKW01-6G-JB requires 16.00mm. This 3.70mm difference necessitates enlargement of the existing panel opening or use of an adapter ring. Verify panel material thickness and structural integrity before modification.

Q: Are there any electrical performance differences between these parts?

A: The substitute provides enhanced electrical performance: 3A current capacity versus 1A, extended operating temperature range (70°C maximum versus 50°C), and doubled electrical life (100,000 cycles versus 50,000 cycles). These improvements do not affect compatibility with existing 1A-rated circuits.

Q: Why is the KB16MKW01-6G-JB obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The YB16MKW01-6G-JB represents the active successor within the NKK Switches pushbutton switch portfolio, offering equivalent functionality with enhanced specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the KB16MKW01-6G-JB and YB16MKW01-6G-JB maintain ROHS3 compliance, ensuring compatibility with RoHS-regulated applications and supply chains.

Q: What is the difference between mechanical life and electrical life ratings?

A: Mechanical life (100,000 cycles for the main part, 200,000 for the substitute) measures physical actuator durability through repeated press cycles. Electrical life (50,000 cycles for the main part, 100,000 for the substitute) measures the contact switching capability under electrical load. Both ratings indicate component longevity under specified operating conditions.
