KB16SKW01-5D-AB Equivalent & Substitute Parts

Part Overview

The KB16SKW01-5D-AB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with LED illumination in amber. This panel-mount component is rated for 1A at 125V AC and 30V DC, with a square black button actuator and white window. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16SKW01-5D-AB is determined by the following critical parameters:

• Circuit configuration (SPDT required)
• Switch function (On-On operation)
• Voltage ratings (125V AC minimum, 30V DC minimum)
• Illumination type and voltage (LED, Amber, 2 VDC)
• Mounting configuration (Panel Mount, Front)
• Actuator type and appearance (Square, Button, Black with White Window)
• Operating temperature range (-25°C to 50°C)
• Regulatory compliance (RoHS3, REACH Unaffected)

The YB16SKW01-5D-AB qualifies as a substitute based on matching all critical parameters. While this part exceeds the original specifications in current rating (3A vs. 1A), mechanical life (200,000 vs. 100,000 cycles), and electrical life (100,000 vs. 50,000 cycles), these enhancements do not create incompatibility. The panel cutout dimension difference (16.00mm vs. 12.30mm) and termination style variation (Solder, Quick Connect vs. Solder Lug) require mechanical and electrical integration assessment during implementation.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-5D-AB is functionally equivalent to the KB16SKW01-5D-AB for applications requiring SPDT pushbutton switches with amber LED illumination at 2 VDC. Both parts maintain identical voltage ratings, operating temperature ranges, and regulatory compliance status (RoHS3 Compliant, EAR99 classification).

The substitute part offers enhanced performance characteristics with higher current capacity (3A vs. 1A) and extended mechanical and electrical life ratings. These improvements provide design margin without introducing incompatibility.

Critical integration considerations include panel cutout diameter (16.00mm for YB16SKW01-5D-AB vs. 12.30mm for KB16SKW01-5D-AB) and termination method (Quick Connect 0.110" vs. Solder Lug). Panel modifications or adapter solutions may be required depending on existing mechanical design. Electrical integration must account for the different termination styles during PCB or harness design.

The YB16SKW01-5D-AB is currently in active production status, ensuring supply chain availability and long-term support compared to the obsolete KB16SKW01-5D-AB.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5D-AB directly replace the KB16SKW01-5D-AB without modification?

A: Electrical substitution is valid. However, mechanical integration requires assessment of panel cutout dimensions. The YB16SKW01-5D-AB requires a 16.00mm circular cutout versus 12.30mm for the original part. Panel modification or mechanical adapter may be necessary. Termination style differences (Quick Connect vs. Solder Lug) require electrical integration review.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching circuit configuration (SPDT), switch function (On-On), voltage ratings (125V AC, 30V DC), illumination specifications (LED, Amber, 2 VDC), mounting type (Panel Mount, Front), actuator type (Square, Button), and operating temperature range (-25°C to 50°C). Regulatory compliance (RoHS3, REACH Unaffected) must also align.

Q: Does the higher current rating of the YB16SKW01-5D-AB create compatibility issues?

A: No. The 3A rating of the YB16SKW01-5D-AB exceeds the 1A requirement of the original application, providing design margin. This enhancement does not create electrical incompatibility in circuits designed for 1A operation.

Q: Are there differences in mechanical life between these parts?

A: Yes. The YB16SKW01-5D-AB provides 200,000 mechanical cycles compared to 100,000 cycles for the KB16SKW01-5D-AB. Similarly, electrical life is rated at 100,000 cycles versus 50,000 cycles. These improvements extend component service life without affecting functional compatibility.

Q: What is the impact of different termination styles?

A: The KB16SKW01-5D-AB uses Solder Lug termination, while the YB16SKW01-5D-AB provides Solder and Quick Connect 0.110" (2.8mm) options. Electrical integration design must accommodate the termination method selected. Quick Connect termination may simplify assembly in some applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the KB16SKW01-5D-AB and YB16SKW01-5D-AB are RoHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.
