Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01B-5C-AB is determined by the following critical parameters:

Core Functional Requirements:

• SPDT circuit configuration (mandatory for switching logic compatibility)
• On-Momentary switch function (required for application behavior)
• Red LED illumination at 1.9V nominal (for visual indication consistency)
• Panel mount, front installation capability (for mechanical fit)
• Operating temperature range of -25°C to 50°C (environmental compatibility)

Electrical Compatibility Criteria:

• Voltage ratings must meet or exceed 125V AC and 30V DC
• Current rating must support the application load (minimum 1A AC/DC)

Mechanical and Environmental Compatibility:

• Actuator type: Square button configuration
• Termination style compatibility with circuit board design
• Panel cutout dimensions must accommodate physical installation

The YB15SKW01-5C-AB meets these substitution criteria while offering enhanced performance characteristics in mechanical and electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C-AB is a direct functional substitute for the obsolete KB15SKW01B-5C-AB. Both components are manufactured by NKK Switches and share identical circuit configuration, voltage ratings, and illumination specifications. The substitute part offers superior performance with a 3A current rating (compared to 1A) and extended mechanical and electrical life cycles, providing enhanced reliability for applications requiring the KB15SKW01B-5C-AB.

The YB15SKW01-5C-AB is currently in active production status, ensuring availability for new designs and replacement applications. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and operate across the same temperature range.

The primary design consideration is panel cutout diameter: the KB15SKW01B-5C-AB requires a 12.30mm circular cutout, while the YB15SKW01-5C-AB requires 16.00mm. Panel modifications may be necessary if retrofitting the substitute into existing enclosures designed for the original part.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C-AB directly replace the KB15SKW01B-5C-AB in existing applications?

A: Functionally, yes. Both parts share identical SPDT circuit configuration, voltage ratings (125V AC / 30V DC), and illumination specifications (LED, Red, 1.9V). The YB15SKW01-5C-AB provides higher current capacity (3A vs. 1A) and extended operational life. However, the panel cutout diameter differs (16.00mm vs. 12.30mm), requiring mechanical panel modification for installation in existing enclosures.

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

A: The primary differences are: (1) Product status—KB15SKW01B-5C-AB is obsolete while YB15SKW01-5C-AB is active; (2) Current rating—3A vs. 1A; (3) Mechanical life—1,000,000 vs. 100,000 cycles; (4) Electrical life—100,000 vs. 50,000 cycles; (5) Panel cutout diameter—16.00mm vs. 12.30mm; (6) Termination style—Quick Connect 0.110" vs. Solder Lug.

Q: Are there any compliance or certification differences?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and operate within -25°C to 50°C temperature range. The KB15SKW01B-5C-AB is explicitly ROHS3 compliant. RoHS status for the YB15SKW01-5C-AB is not specified in available documentation.

Q: What is the impact of the different termination styles?

A: The KB15SKW01B-5C-AB uses Solder Lug termination, while the YB15SKW01-5C-AB offers both Solder and Quick Connect 0.110" (2.8mm) options. Circuit board design must accommodate the selected termination style. Quick Connect termination may simplify assembly and replacement procedures.

Q: Is the YB15SKW01-5C-AB suitable for high-cycle applications?

A: Yes. The YB15SKW01-5C-AB is rated for 1,000,000 mechanical cycles and 100,000 electrical cycles, making it appropriate for applications requiring extended operational life compared to the original KB15SKW01B-5C-AB specification.
