Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16SKW01-5C-AB is evaluated based on the following critical parameters that define functional equivalence:

Electrical Compatibility Parameters:

• Circuit configuration (SPDT maintained)
• Switch function (On-On maintained)
• Voltage ratings (AC 125V, DC 30V maintained)
• Illumination type and color (LED, Red maintained)
• Illumination voltage (1.9 VDC maintained)

Mechanical Compatibility Parameters:

• Mounting type (Panel Mount, Front maintained)
• Actuator type (Square, Button maintained)
• Operating temperature range (-25°C to 50°C maintained)
• Termination compatibility with circuit board design

Performance Characteristics:

• Current rating tolerance (1A minimum requirement)
• Mechanical and electrical life cycles

The YB16SKW01-5C-AB qualifies as a substitute part because it maintains all critical electrical parameters, mounting configuration, and environmental specifications. Differences in current rating (3A vs. 1A), panel cutout diameter (16.00mm vs. 12.30mm), mechanical life (200,000 vs. 100,000 cycles), and electrical life (100,000 vs. 50,000 cycles) represent enhancements or design variations that do not prevent substitution. The termination style difference (Solder Lug vs. Solder/Quick Connect) requires circuit board design verification.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-5C-AB is an active production substitute for the obsolete KB16SKW01-5C-AB. Selection of the YB16SKW01-5C-AB is supported by:

Product Status: The substitute part is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Electrical Equivalence: Both parts maintain identical voltage ratings (AC 125V, DC 30V), circuit configuration (SPDT), and illumination specifications (LED, Red, 1.9 VDC). The YB16SKW01-5C-AB current rating of 3A exceeds the 1A requirement of the KB16SKW01-5C-AB, providing additional design margin.

Mechanical Compatibility: Both parts feature identical mounting type (Panel Mount, Front), actuator type (Square, Button), and operating temperature range (-25°C to 50°C).

Design Considerations: The panel cutout diameter difference (16.00mm vs. 12.30mm) requires panel modification or redesign. The termination style change from Solder Lug to Solder/Quick Connect requires circuit board connection verification. Enhanced mechanical life (200,000 vs. 100,000 cycles) and electrical life (100,000 vs. 50,000 cycles) of the substitute part provide improved reliability margins.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5C-AB directly replace the KB16SKW01-5C-AB without any modifications?

A: Electrical and functional replacement is direct. However, the panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification. The termination style change from Solder Lug to Solder/Quick Connect requires circuit board connection verification before installation.

Q: What is the significance of the current rating difference (1A vs. 3A)?

A: The KB16SKW01-5C-AB is rated for 1A maximum current. The YB16SKW01-5C-AB is rated for 3A maximum current. This difference does not prevent substitution; the higher rating of the substitute part provides additional design margin and is suitable for applications requiring 1A or less.

Q: Are the illumination specifications identical between both parts?

A: Yes. Both parts feature LED illumination in red color with a nominal voltage of 1.9 VDC, ensuring identical visual indication and power supply requirements.

Q: What is the impact of the mechanical and electrical life cycle differences?

A: The KB16SKW01-5C-AB specifies 100,000 mechanical cycles and 50,000 electrical cycles. The YB16SKW01-5C-AB specifies 200,000 mechanical cycles and 100,000 electrical cycles. The substitute part provides doubled cycle life, resulting in extended component reliability and service life.

Q: How does the termination style change affect circuit board design?

A: The KB16SKW01-5C-AB uses Solder Lug termination. The YB16SKW01-5C-AB uses Solder and Quick Connect (0.110" / 2.8mm) termination. Circuit board connection points must be verified for compatibility with the Quick Connect terminal configuration before implementation.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both parts operate across the identical temperature range of -25°C to 50°C, ensuring equivalent thermal performance in the same environmental conditions.
