Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the KB15CKW01-5F-JB is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Circuit configuration (SPDT maintained)
• Switch function (On-Mom maintained)
• Voltage ratings (125V AC / 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Actuator type (Round, Button)
• Illumination type and color (LED, Green)
• Operating temperature range (-25°C to 50°C minimum)
• Regulatory compliance (ROHS3, REACH Unaffected)

Allowable Variation Parameters:

• Current rating (equal or higher amperage acceptable)
• Mechanical and electrical life cycles (equal or higher acceptable)
• Panel cutout diameter (physical installation consideration)
• Termination style (design-dependent)
• Illumination voltage (minor tolerance acceptable within LED specifications)

The YB15CKW01-5F-JB qualifies as a substitute based on these criteria, with enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-5F-JB serves as a direct functional substitute for the obsolete KB15CKW01-5F-JB. Both components maintain identical circuit configuration, voltage ratings, and operating temperature specifications. The substitute part offers enhanced performance through increased current capacity (3A versus 1A), extended mechanical life (1,000,000 versus 100,000 cycles), and doubled electrical life (100,000 versus 50,000 cycles).

Both parts maintain full ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system replacements. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability.

Physical installation requires consideration of panel cutout diameter differences: the main part requires a 12.30mm circular cutout, while the substitute requires 16.00mm. Termination style differs between solder lug (main part) and solder with quick connect 0.110" option (substitute part), necessitating circuit board design verification.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKW01-5F-JB directly replace the KB15CKW01-5F-JB in existing designs?

A: Functional replacement is possible with design verification. The substitute maintains identical circuit behavior, voltage ratings, and illumination characteristics. However, panel cutout diameter and termination style differences require mechanical and electrical redesign consideration.

Q: What is the significance of the increased current rating in the substitute part?

A: The YB15CKW01-5F-JB supports 3A current capacity compared to 1A in the original part. This allows the substitute to handle higher-load applications without derating. Existing 1A applications operate well within the substitute's specifications.

Q: Are there compatibility concerns with the illumination voltage difference?

A: The illumination voltage difference (2.1 VDC versus 2.2 VDC) is within standard LED operating tolerance and does not affect functional compatibility. Both parts use identical LED green illumination type.

Q: How do the mechanical and electrical life specifications affect component selection?

A: The substitute part's extended life cycles (1,000,000 mechanical and 100,000 electrical) indicate improved durability and longer service intervals. Applications requiring high-cycle operation benefit from this enhancement, while lower-cycle applications operate safely with either part.

Q: What installation considerations apply when switching from KB15CKW01-5F-JB to YB15CKW01-5F-JB?

A: Panel cutout diameter must be enlarged from 12.30mm to 16.00mm. Termination connections require verification: the original uses solder lug termination, while the substitute offers solder or quick connect 0.110" options. Circuit board layout modification is necessary.

Q: Are both parts suitable for new product designs?

A: The KB15CKW01-5F-JB is obsolete and unsuitable for new designs. The YB15CKW01-5F-JB is active production status and recommended for all new applications requiring SPDT pushbutton switch functionality with LED illumination.
