KB16SKW01-05-JG Equivalent & Substitute Parts

Part Overview

The KB16SKW01-05-JG is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with on-on switch function. This component is rated for 1A at 125V AC and 30V DC, with incandescent blue illumination at 5VAC nominal voltage. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16SKW01-05-JG is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Panel Mount, Front
• Voltage rating: Minimum 125V AC / 30V DC
• Operating temperature range: -25°C to 50°C or broader
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Current rating: May exceed 1A (higher ratings are backward compatible)
• Illumination type: May differ (incandescent to LED acceptable)
• Illumination voltage: May differ if system design accommodates
• Mechanical and electrical life: May exceed specified values
• Panel cutout diameter: Requires mechanical redesign if different
• Termination style: Requires circuit board redesign if different

The YB16SKW01-6G-JB qualifies as a substitute based on matching SPDT circuit, on-on function, panel mount configuration, and voltage ratings. The higher current rating (3A vs 1A) and extended mechanical/electrical life provide enhanced performance margins. Differences in illumination technology (LED vs incandescent), illumination voltage (3.6VDC vs 5VAC), panel cutout diameter (16.00mm vs 12.30mm), and termination style (solder/quick connect vs solder lug) require system-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Feasibility: The YB16SKW01-6G-JB provides functional equivalence for SPDT on-on switching applications within the specified voltage and current parameters. Both components maintain ROHS3 compliance and identical operating temperature ranges, supporting regulatory and environmental requirements.

System Integration Considerations: Implementation of YB16SKW01-6G-JB requires evaluation of three design modifications:

1. Panel Cutout Diameter: The 16.00mm diameter of YB16SKW01-6G-JB exceeds the 12.30mm requirement of KB16SKW01-05-JG, necessitating panel drilling or mechanical redesign.

2. Illumination Circuit: The transition from 5VAC incandescent to 3.6VDC LED illumination requires modification of the illumination power supply and control circuitry.

3. Electrical Termination: The shift from solder lug to solder/quick connect 0.110" (2.8mm) termination requires circuit board layout modification.

Performance Enhancement: The YB16SKW01-6G-JB offers superior reliability margins with 3A current rating (versus 1A) and doubled mechanical/electrical life specifications (200,000 and 100,000 cycles respectively), providing extended component longevity in high-cycle applications.

Product Availability: KB16SKW01-05-JG is obsolete; YB16SKW01-6G-JB is active production status, ensuring long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can YB16SKW01-6G-JB replace KB16SKW01-05-JG without any modifications?

A: No. While both components share identical SPDT circuit configuration, on-on function, and voltage ratings, three design modifications are required: panel cutout diameter increase (12.30mm to 16.00mm), illumination voltage change (5VAC incandescent to 3.6VDC LED), and termination style change (solder lug to solder/quick connect).

Q: What is the impact of the higher current rating (3A vs 1A) on system design?

A: The 3A rating of YB16SKW01-6G-JB is backward compatible with applications rated for 1A. No circuit modifications are required for current handling; the higher rating provides additional safety margin and component longevity.

Q: Are there mechanical compatibility issues with panel mounting?

A: Yes. The panel cutout diameter differs: KB16SKW01-05-JG requires 12.30mm, while YB16SKW01-6G-JB requires 16.00mm. Panel drilling or mechanical redesign is necessary for proper mounting.

Q: How does the illumination change from incandescent to LED affect system operation?

A: The illumination voltage differs (5VAC to 3.6VDC) and the technology changes (incandescent to LED). The illumination power supply and control circuitry must be modified to accommodate the new voltage and DC polarity requirements. Both maintain blue color output.

Q: What are the termination compatibility requirements?

A: KB16SKW01-05-JG uses solder lug termination, while YB16SKW01-6G-JB uses solder and quick connect 0.110" (2.8mm) termination. Circuit board layout and connection methodology must be redesigned to accommodate the different termination style.

Q: Is RoHS compliance maintained with the substitute part?

A: Yes. Both KB16SKW01-05-JG and YB16SKW01-6G-JB are ROHS3 compliant, maintaining regulatory compliance in the substitution.

Q: What is the significance of product status (Obsolete vs Active)?

A: KB16SKW01-05-JG is obsolete and no longer manufactured, creating supply chain risk. YB16SKW01-6G-JB is active production status, ensuring availability for new designs and ongoing system maintenance.
