KB16KKW01-5C-JC Equivalent & Substitute Parts

Part Overview

The KB16KKW01-5C-JC is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with on-on switching function. This component is rated for 1A at 125V AC and 30V DC, with red LED illumination at 1.9VDC nominal. The switch employs panel mount snap-in installation with solder lug termination and a 12.30mm circular panel cutout. The product is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16KKW01-5C-JC is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Voltage ratings (125V AC minimum, 30V DC minimum)
• Illumination type and color (LED, Red)
• Illumination voltage (1.9VDC nominal)
• Mounting type (Panel Mount, Snap-In)
• Actuator type (Square, Button)
• Operating temperature range (-25°C to 50°C minimum)

Allowable Variation Parameters:

• Current rating (equal or greater than 1A)
• Mechanical life (equal or greater than 100,000 cycles)
• Electrical life (equal or greater than 50,000 cycles)
• Panel cutout dimensions (mechanical accommodation required)
• Termination style (functional equivalence required)

The YB16KKW01-5C-JC qualifies as a substitute part because it maintains all mandatory compatibility parameters while exceeding allowable variation thresholds in current rating (3A vs. 1A), mechanical life (200,000 vs. 100,000 cycles), and electrical life (100,000 vs. 50,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB16KKW01-5C-JC is a qualified substitute for the obsolete KB16KKW01-5C-JC based on functional and electrical equivalence. The substitute part maintains identical circuit configuration, voltage ratings, illumination specifications, and operating temperature range. Both components are classified under the same ECCN (EAR99) and share identical moisture sensitivity levels.

The YB16KKW01-5C-JC offers enhanced performance characteristics with higher current rating (3A vs. 1A), extended mechanical life (200,000 vs. 100,000 cycles), and doubled electrical life (100,000 vs. 50,000 cycles). The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Panel cutout dimension differences (16.00mm vs. 12.30mm) require mechanical accommodation during installation. Termination style variation (Quick Connect 0.110" vs. Solder Lug) necessitates circuit board connection method adjustment. These mechanical and termination differences do not affect electrical functionality or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the YB16KKW01-5C-JC directly replace the KB16KKW01-5C-JC without circuit modifications?

A: Electrical functionality is directly compatible. However, mechanical installation requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination connection method differs (Quick Connect vs. Solder Lug), requiring circuit board connection adjustment.

Q: Are the voltage and current ratings compatible between these parts?

A: Yes. The substitute part maintains 125V AC and 30V DC ratings. The increased current rating (3A vs. 1A) is backward compatible and does not create electrical conflicts in circuits designed for 1A operation.

Q: Do both parts have identical illumination specifications?

A: Yes. Both components feature red LED illumination at 1.9VDC nominal voltage, ensuring identical visual indication and power supply requirements.

Q: What is the impact of the extended mechanical and electrical life ratings?

A: The YB16KKW01-5C-JC provides extended component longevity (200,000 mechanical cycles vs. 100,000, and 100,000 electrical cycles vs. 50,000). This represents improved reliability and extended service life in applications with high cycle frequency.

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

A: Both components share EAR99 classification and MSL 1 (Unlimited) moisture sensitivity rating. The main part specifies ROHS3 compliance; the substitute part compliance status is not specified in available documentation.

Q: What panel cutout modifications are required for installation?

A: The panel cutout must be enlarged from 12.30mm to 16.00mm circular diameter. This is a mechanical accommodation requirement and does not affect electrical performance.
