Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15NKW01-5F-JD is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Mounting type (Panel Mount, Snap-In)
• Illumination type and color (LED, Green)
• Operating temperature range (-25°C to 50°C)
• Voltage ratings (125V AC minimum, 30V DC)
• RoHS compliance status

Allowable Variation Parameters:

• Current rating (may exceed 1A)
• Mechanical and electrical life cycles (may exceed specified values)
• Panel cutout diameter (physical accommodation required)
• Illumination voltage (within compatible LED driver range)
• Termination style (provided electrical connection is maintained)
• Product status (active parts preferred for obsolete replacements)

The YB15NKW01-5F-JD qualifies as a substitute based on matching all mandatory parameters while offering enhanced performance characteristics in current rating, mechanical life, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

The YB15NKW01-5F-JD is a qualified substitute for the obsolete KB15NKW01-5F-JD based on functional equivalence across all critical electrical and mechanical parameters. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Enhanced current rating (3A vs. 1A) provides additional design margin for applications within the original 1A specification
• Increased mechanical life (1,000,000 vs. 100,000 cycles) and electrical life (100,000 vs. 50,000 cycles) extend component service life
• Identical voltage ratings, circuit configuration, and illumination specifications maintain functional compatibility

Physical integration requires accommodation of the larger panel cutout diameter (16.00mm vs. 12.30mm). Termination style differs between solder lug and quick-connect options; electrical connection methodology must be evaluated for the specific application. Both parts maintain identical operating temperature range and moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the YB15NKW01-5F-JD directly replace the KB15NKW01-5F-JD without circuit modifications?

A: Electrical substitution is direct for applications operating at or below 1A. The higher current rating of the substitute part does not affect operation in lower-current circuits. Panel cutout diameter differences require mechanical accommodation.

Q: What is the significance of the panel cutout diameter difference?

A: The YB15NKW01-5F-JD requires a 16.00mm circular cutout compared to the 12.30mm cutout for the KB15NKW01-5F-JD. Existing panel mounting holes must be enlarged or the panel assembly modified to accommodate the larger switch body.

Q: Are the illumination specifications compatible?

A: Both parts feature green LED illumination with nominal voltages of 2.1 VDC (KB series) and 2.0 VDC (YB series). These values are within typical LED driver tolerance ranges and are functionally equivalent for illumination purposes.

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

A: The KB15NKW01-5F-JD uses solder lugs while the YB15NKW01-5F-JD offers solder and quick-connect (0.110" / 2.8mm) termination options. Connection method selection depends on the specific wiring and assembly requirements of the application.

Q: Does the substitute part maintain RoHS compliance?

A: The KB15NKW01-5F-JD is specified as ROHS3 compliant. RoHS status for the YB15NKW01-5F-JD is not provided in the available documentation and should be confirmed with the manufacturer if RoHS compliance is a requirement.

Q: Are there any temperature or environmental limitations?

A: Both parts operate across the identical temperature range of -25°C to 50°C and maintain MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent environmental performance.
