KB16SKW01-01-JC Equivalent & Substitute Parts

Part Overview

The KB16SKW01-01-JC is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. This illuminated panel mount switch features a square button actuator with red neon illumination and is designed for front panel mounting with a circular 12.30mm diameter cutout. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16SKW01-01-JC is based on the following allowable parameter variations:

Electrical Parameters (Must Match or Exceed):

• Circuit configuration must remain SPDT
• Voltage ratings must support minimum 125V AC and 30V DC operation
• Current rating may exceed 1A; higher ratings are acceptable for direct substitution
• Electrical life may exceed 50,000 cycles

Mechanical Parameters (Must Match or Exceed):

• Mounting type must be Panel Mount, Front
• Panel cutout diameter must accommodate the original 12.30mm specification or smaller
• Mechanical life may exceed 100,000 cycles
• Operating temperature range must encompass -25°C to 50°C

Functional Parameters (Must Match):

• Switch function must be On-On
• Actuator type must be Square, Button
• Illumination color must be Red

Compliance Parameters (Must Match or Exceed):

• RoHS3 compliance required
• REACH Unaffected status required

The YB16SKW01-5C-JC meets all substitution criteria with improvements in current rating (3A vs. 1A), mechanical life (200,000 vs. 100,000 cycles), and electrical life (100,000 vs. 50,000 cycles). However, the larger panel cutout diameter (16.00mm vs. 12.30mm) and different illumination technology (LED vs. Neon) require mechanical and electrical integration assessment.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-5C-JC is the designated substitute for the obsolete KB16SKW01-01-JC. Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for new designs and legacy system replacements.

The substitute part provides superior electrical and mechanical performance with a 3A current rating and extended operational life (200,000 mechanical cycles, 100,000 electrical cycles). The active product status of the YB16SKW01-5C-JC ensures long-term availability and supply chain continuity.

Integration considerations include panel cutout modification (from 12.30mm to 16.00mm diameter), termination style change (from Solder Lug to Solder with Quick Connect option), and illumination voltage adjustment (from 110 VAC Neon to 1.9 VDC LED). These differences require circuit design review and mechanical panel layout assessment prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5C-JC directly replace the KB16SKW01-01-JC without modifications?

A: Electrical substitution is valid; the YB16SKW01-5C-JC meets or exceeds all electrical specifications. However, mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Illumination voltage differs (110 VAC to 1.9 VDC), necessitating circuit redesign for the LED illumination system.

Q: What are the key differences in illumination between these parts?

A: The KB16SKW01-01-JC uses Neon illumination at 110 VAC nominal voltage. The YB16SKW01-5C-JC uses LED illumination at 1.9 VDC nominal voltage. LED technology provides lower power consumption and extended operational life compared to neon.

Q: Is the current rating increase from 1A to 3A a concern for substitution?

A: No. Higher current ratings are acceptable for direct electrical substitution. The 3A rating of the YB16SKW01-5C-JC provides additional design margin and is compatible with circuits designed for 1A operation.

Q: What packaging differences exist between these parts?

A: The KB16SKW01-01-JC is supplied with standard packaging. The YB16SKW01-5C-JC is supplied in Bulk packaging. Both are new original stock from NKK Switches.

Q: Are there termination compatibility issues?

A: Yes. The KB16SKW01-01-JC uses Solder Lug termination. The YB16SKW01-5C-JC offers Solder with Quick Connect - 0.110" (2.8mm) termination. PCB layout and connector design must accommodate the different termination style.

Q: Why is the KB16SKW01-01-JC classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by NKK Switches. The YB16SKW01-5C-JC is the active equivalent, ensuring continued availability for new designs and system maintenance.
