Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-5C-AB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Voltage ratings (125V AC / 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Illumination type and color (LED, Red)
• Illumination voltage (1.9V Nominal)
• Actuator type (Square Button)
• Operating temperature range (-25°C to +50°C)
• RoHS compliance status

Allowable Variation Parameters:

• Current rating (may exceed 1A)
• Mechanical and electrical life cycles (may exceed specified values)
• Termination style (alternative connection methods acceptable if electrically equivalent)
• Panel cutout diameter (may differ if mechanical integration is feasible)
• Product status (active parts preferred for obsolete originals)

The YB15SKW01-5C-AB meets substitution criteria through matching core electrical and functional specifications while offering enhanced performance characteristics in current capacity and operational life cycles.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C-AB is a direct functional substitute for the obsolete KB15SKW01-5C-AB. Both components are manufactured by NKK Switches and maintain identical electrical specifications for voltage and circuit configuration. The substitute part offers superior performance through increased current capacity (3A versus 1A) and extended operational life cycles (1,000,000 mechanical cycles versus 100,000), providing enhanced reliability for applications requiring the KB15SKW01-5C-AB functionality.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility. The primary design consideration involves panel cutout diameter accommodation: the substitute requires a 16.00mm circular opening compared to the original 12.30mm specification. Termination style differs between solder lug (original) and solder with quick-connect option (substitute), requiring circuit board layout evaluation.

The active product status of the YB15SKW01-5C-AB ensures ongoing availability and supply chain continuity, eliminating obsolescence risk associated with the original part.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C-AB directly replace the KB15SKW01-5C-AB in existing designs?

A: Electrical substitution is valid. The YB15SKW01-5C-AB maintains identical SPDT circuit configuration, voltage ratings (125V AC / 30V DC), and illumination specifications (LED, Red, 1.9V). Panel cutout diameter differs (16.00mm versus 12.30mm), requiring mechanical integration assessment. Termination style variation (quick-connect option available) necessitates circuit board connection compatibility review.

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

A: Current rating increases from 1A to 3A. Mechanical life extends from 100,000 to 1,000,000 cycles. Electrical life doubles from 50,000 to 100,000 cycles. Panel cutout diameter increases from 12.30mm to 16.00mm. Termination options expand to include quick-connect capability. Product status changes from obsolete to active.

Q: Are both parts RoHS compliant?

A: Yes. Both KB15SKW01-5C-AB and YB15SKW01-5C-AB are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the impact of the larger panel cutout diameter on substitution?

A: The YB15SKW01-5C-AB requires a 16.00mm circular panel opening versus 12.30mm for the original part. Existing panel cutouts must be enlarged or new panels fabricated. This represents the primary mechanical constraint for retrofit applications.

Q: Does the increased current rating affect circuit design?

A: The 3A rating of the YB15SKW01-5C-AB exceeds the 1A requirement of the original part, providing design margin. No circuit modifications are necessary. Applications originally designed for 1A operation remain fully compatible.

Q: Are there termination compatibility considerations?

A: The original part uses solder lug termination. The substitute offers solder lug and quick-connect (0.110" / 2.8mm) options. Circuit board layout and connector specifications must be evaluated to confirm termination method compatibility.
