Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15RKW01B-CC is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

• Circuit Configuration: SPDT (maintains electrical functionality)
• Switch Function: On-Mom (momentary operation requirement)
• Voltage Rating - AC: 125V minimum (electrical safety requirement)
• Voltage Rating - DC: 30V minimum (electrical safety requirement)
• Mounting Type: Panel Mount, Front (mechanical installation requirement)
• Actuator Type: Rectangular, Button (form factor requirement)
• Operating Temperature Range: -25°C to 70°C minimum (environmental requirement)

Allowable Variation Parameters:

• Current Rating: May exceed 1A (higher current rating provides operational margin)
• Mechanical Life: May exceed 100,000 cycles (improved durability acceptable)
• Electrical Life: May exceed 50,000 cycles (improved durability acceptable)
• Panel Cutout Diameter: Larger diameter acceptable with mechanical redesign consideration
• Termination Style: Alternative termination acceptable if electrical connection is maintained
• Actuator Color: Variation acceptable if functional requirement is met

The YB15RKW01-CB meets all mandatory compatibility parameters while exceeding several allowable variation parameters, qualifying it as a valid substitute.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01-CB is a qualified substitute for the KB15RKW01B-CC based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical voltage ratings (125V AC / 30V DC) and circuit configuration (SPDT). The YB15RKW01-CB provides enhanced current capacity (3A versus 1A), which is operationally compatible with applications designed for the original 1A component.

Mechanical Compatibility: Both components feature identical mounting type (Panel Mount, Front) and actuator configuration (Rectangular, Button). The panel cutout diameter difference (16.00mm versus 12.30mm) requires mechanical panel redesign or adapter consideration during implementation.

Regulatory Compliance: Both components maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory standing.

Product Status Advantage: The YB15RKW01-CB is currently in active production status, providing supply chain continuity and long-term availability compared to the obsolete KB15RKW01B-CC.

Durability Enhancement: The substitute component provides superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), extending component service life in the application.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKW01-CB directly replace the KB15RKW01B-CC without any modifications?

A: Electrical and functional replacement is direct. Mechanical panel modification is required due to the panel cutout diameter difference (16.00mm versus 12.30mm). Termination style differs (Quick Connect available on substitute versus Solder Lug on original), requiring wiring harness adaptation.

Q: What is the significance of the current rating difference (1A versus 3A)?

A: The higher current rating on the YB15RKW01-CB indicates greater electrical capacity. Applications designed for 1A operation remain fully compatible, as the component will operate within its rated specifications at lower current levels.

Q: Are there any compliance or certification differences between these components?

A: Both components maintain identical RoHS3 compliance status and MSL Level 1 moisture sensitivity rating. No compliance disadvantage exists with the substitute component.

Q: What does the panel cutout diameter difference mean for implementation?

A: The original component requires a 12.30mm circular cutout; the substitute requires 16.00mm. Existing panel tooling must be modified or a mechanical adapter must be designed to accommodate the larger diameter.

Q: Why does the substitute have different termination options?

A: The YB15RKW01-CB offers both Solder and Quick Connect (0.110" / 2.8mm) termination options, providing installation flexibility. Solder termination is compatible with the original component's connection method.

Q: Is the substitute component more reliable than the original?

A: The YB15RKW01-CB demonstrates extended mechanical and electrical life ratings (10x and 2x respectively), indicating enhanced durability characteristics within the same operating temperature range and environmental classification.
