KB16RKW01-12-EB Equivalent & Substitute Parts

Part Overview

The KB16RKW01-12-EB 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 incandescent yellow illumination at 12VAC nominal voltage. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where similar electrical and mechanical characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16RKW01-12-EB is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must support minimum 1A operation

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Rectangular Button
• Panel cutout diameter must accommodate the physical interface

Environmental & Operational Requirements:

• Operating temperature range must encompass -25°C to 50°C
• Mechanical life must be sufficient for application demands
• Termination style must be compatible with circuit board or wiring interface

Regulatory & Compliance Requirements:

• RoHS3 compliance status
• Moisture Sensitivity Level 1 classification

The YB16RKW01-5D12-JD meets these substitution criteria while offering enhanced electrical life and mechanical durability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB16RKW01-5D12-JD is an active product with ROHS3 compliance, providing a direct functional substitute for the obsolete KB16RKW01-12-EB. Both components maintain identical voltage ratings (125V AC / 30V DC) and operating temperature specifications (-25°C to 50°C), ensuring electrical compatibility in existing circuit designs.

The substitute part offers enhanced reliability through doubled mechanical life (200,000 cycles versus 100,000 cycles) and doubled electrical life (100,000 cycles versus 50,000 cycles). Current rating is increased to 3A, providing additional design margin for applications originally specified at 1A.

Key design considerations for implementation:

Panel Cutout Modification: The substitute requires a 16.00mm diameter panel cutout compared to the original 12.30mm diameter. Mechanical panel redesign is necessary.

Illumination Voltage: The substitute operates on 12VDC rather than 12VAC. Power supply configuration must be verified for DC compatibility.

Illumination Color: LED amber illumination replaces incandescent yellow. Visual appearance and brightness characteristics differ from the original design.

Termination Interface: The substitute provides both solder and quick-connect 0.110" (2.8mm) termination options, offering installation flexibility beyond the original solder lug configuration.

Frequently Asked Questions (FAQ)

Q: Can the YB16RKW01-5D12-JD directly replace the KB16RKW01-12-EB without modifications?

A: Electrical substitution is direct for voltage and current requirements. However, mechanical panel modifications are required due to the larger 16.00mm cutout diameter. Illumination voltage must be changed from 12VAC to 12VDC, and power supply configuration must be updated accordingly.

Q: What are the key electrical differences between these parts?

A: Both maintain identical AC and DC voltage ratings (125V AC / 30V DC) and SPDT on-on switching function. The substitute provides higher current capacity (3A versus 1A) and extended operational life ratings (200,000 mechanical cycles and 100,000 electrical cycles versus 100,000 and 50,000 respectively).

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant with Moisture Sensitivity Level 1 classification. The substitute is an active product, while the original is obsolete. Both carry identical ECCN (EAR99) and HTSUS (8536.50.9033) classifications.

Q: What illumination differences exist between the parts?

A: The original uses incandescent yellow illumination at 12VAC. The substitute uses LED amber illumination at 12VDC. LED technology provides longer operational life and lower power consumption but produces different color appearance and brightness characteristics.

Q: Is the termination style compatible between the two parts?

A: The original uses solder lug termination. The substitute provides both solder and quick-connect 0.110" (2.8mm) termination options, offering greater installation flexibility. Existing solder connections can be adapted to the substitute's solder termination option.

Q: What is the mechanical life difference, and why does it matter?

A: The substitute provides 200,000 mechanical cycles compared to 100,000 cycles in the original. This doubled durability extends component service life and reduces replacement frequency in high-cycle applications.
