KB15SKW01-05-EB Equivalent & Substitute Parts

Part Overview

The KB15SKW01-05-EB is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with on-momentary switch function. This component is rated for 1A at 125V AC and 30V DC, with incandescent yellow illumination at 5VAC nominal voltage. 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 KB15SKW01-05-EB is determined by the following critical parameters:

Circuit and Function Compatibility: The substitute part must maintain SPDT circuit configuration with on-momentary switch function to ensure electrical behavior equivalence in the application.

Voltage and Current Ratings: The substitute must support minimum 125V AC and 30V DC ratings. Parts with higher current ratings (3A versus 1A) are acceptable as they provide enhanced capacity without reducing performance in lower-demand applications.

Mounting and Panel Integration: Panel mount, front-facing configuration with circular cutout dimensions must be compatible. The KB15SKW01-05-EB requires a 12.30mm diameter cutout; substitute parts with larger cutouts (16.00mm) require panel modification.

Illumination Characteristics: While the main part uses incandescent yellow illumination at 5VAC, substitute parts may employ LED technology with different voltage requirements (2VDC versus 5VAC), provided the illumination color remains functionally equivalent and the control circuit accommodates the voltage difference.

Termination and Environmental Compliance: Solder lug termination may be substituted with quick-connect alternatives if the application permits. Both parts must maintain ROHS3 compliance and operate within the specified temperature range (-25°C to 50°C).

The YB15SKW01-5D05-JD qualifies as a substitute based on these criteria, with the primary design consideration being panel cutout diameter and illumination voltage adaptation.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5D05-JD is an active product with current manufacturing support, whereas the KB15SKW01-05-EB is obsolete. Both parts maintain ROHS3 compliance and identical voltage ratings (125V AC / 30V DC), ensuring regulatory and electrical compatibility.

The substitute part provides enhanced reliability through superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles). The increased current rating (3A versus 1A) accommodates higher-demand applications without derating.

Critical design considerations for substitution:

Panel Integration: The YB15SKW01-5D05-JD requires a 16.00mm diameter cutout compared to the 12.30mm requirement of the main part. Existing panel designs must be modified or a new panel assembly fabricated.

Illumination Voltage: The substitute employs 2VDC LED illumination instead of 5VAC incandescent. The control circuit must be adapted to supply the appropriate voltage and current for LED operation. LED illumination provides extended service life and reduced power consumption compared to incandescent technology.

Termination Compatibility: The substitute offers both solder and quick-connect (0.110" / 2.8mm) termination options, providing flexibility for different assembly methods. Existing solder lug connections require adapter harnesses or circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5D05-JD directly replace the KB15SKW01-05-EB without panel modification?

A: No. The YB15SKW01-5D05-JD requires a 16.00mm diameter panel cutout versus the 12.30mm requirement of the KB15SKW01-05-EB. Panel drilling or replacement is necessary for mechanical fit.

Q: Are the voltage ratings identical between these parts?

A: Yes. Both parts are rated for 125V AC and 30V DC, ensuring electrical compatibility in applications designed for the KB15SKW01-05-EB.

Q: What is the impact of the higher current rating on the substitute part?

A: The YB15SKW01-5D05-JD is rated for 3A versus 1A on the main part. This higher rating does not affect performance in applications requiring 1A or less; it simply provides additional capacity margin and is suitable for higher-demand applications.

Q: How does LED illumination differ from incandescent illumination?

A: The substitute uses 2VDC LED illumination (amber color) instead of 5VAC incandescent yellow illumination. LED technology offers extended operational life, lower power consumption, and faster response time. The control circuit must supply appropriate voltage and current for LED operation.

Q: Are both parts RoHS compliant?

A: Yes. Both the KB15SKW01-05-EB and YB15SKW01-5D05-JD are ROHS3 compliant, meeting environmental and regulatory requirements.

Q: What termination options are available on the substitute part?

A: The YB15SKW01-5D05-JD provides both solder and quick-connect (0.110" / 2.8mm) termination styles. The main part uses solder lug termination only. Existing solder connections may require adapter harnesses or circuit board modification.

Q: Is the substitute part currently available?

A: Yes. The YB15SKW01-5D05-JD is an active product with 790 pieces in stock, whereas the KB15SKW01-05-EB is obsolete with limited availability.
