Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01B is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Voltage ratings (125V AC minimum, 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Actuator type (Plunger for Cap)
• Operating temperature range (-25°C to 70°C minimum)

Allowable Variation Parameters:

• Current rating (substitute must equal or exceed 1A)
• Mechanical and electrical life cycles (substitute must equal or exceed specified values)
• Panel cutout diameter (physical accommodation required)
• Termination style (electrical equivalence with mechanical adaptation possible)

The YB15SKW01 meets all mandatory compatibility parameters while exceeding performance specifications in current rating (3A), mechanical life (1,000,000 cycles), and electrical life (100,000 cycles). The substitute maintains identical voltage ratings, operating temperature range, and circuit configuration.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01 is a direct functional equivalent for KB15SKW01B applications. Both components maintain identical electrical specifications for voltage and circuit configuration, with the substitute providing enhanced performance margins in current capacity and operational life cycles.

From a compliance perspective, both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The YB15SKW01 carries active product status, ensuring continued availability and supply chain stability compared to the obsolete KB15SKW01B.

Physical integration requires consideration of panel cutout diameter differences: KB15SKW01B requires 12.30mm circular cutout while YB15SKW01 requires 16.00mm circular cutout. Termination style differs (solder lug versus solder with quick connect 0.110" option), requiring electrical connection method evaluation for specific applications.

Frequently Asked Questions (FAQ)

Q: Can YB15SKW01 directly replace KB15SKW01B in existing designs?

A: Electrical substitution is valid based on identical SPDT circuit configuration, voltage ratings, and operating temperature range. Physical panel integration requires verification of 16.00mm cutout accommodation versus original 12.30mm specification. Termination method compatibility must be confirmed for the specific application.

Q: What are the key differences between these components?

A: The primary differences are current rating (1A versus 3A), mechanical life (100,000 versus 1,000,000 cycles), electrical life (50,000 versus 100,000 cycles), panel cutout diameter (12.30mm versus 16.00mm), and termination style (solder lug versus solder with quick connect option). All differences favor the substitute in performance specifications.

Q: Why is KB15SKW01B obsolete while YB15SKW01 is active?

A: Product lifecycle management by NKK Switches has transitioned the KB series to obsolete status while maintaining the YB series as current production. The YB15SKW01 represents the active equivalent within the manufacturer's current product portfolio.

Q: Are there packaging differences between these parts?

A: KB15SKW01B is supplied in standard packaging while YB15SKW01 is supplied in tray packaging. This difference affects handling and storage procedures but does not impact electrical or mechanical functionality.

Q: What compliance certifications apply to both components?

A: Both KB15SKW01B and YB15SKW01 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.
