Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16SKW01-5F12-AB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Voltage rating - AC (125V minimum)
• Voltage rating - DC (30V minimum)
• Mounting type (Panel Mount, Front)
• Illumination type and color (LED, Green)
• Illumination voltage (12VDC nominal)
• Actuator type (Square, Button)
• Operating temperature range (-25°C to 50°C minimum)

Allowable Variation Parameters:

• Current rating (substitute must meet or exceed 1A)
• Mechanical and electrical life cycles (substitute may exceed specified values)
• Termination style (alternative termination methods acceptable if electrically equivalent)
• Panel cutout dimensions (mechanical accommodation required in host design)
• Product status (active alternatives preferred for obsolete parts)

The YB16SKW01-5F12-AB meets all mandatory matching criteria while exceeding current rating and lifecycle specifications, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-5F12-AB is a qualified substitute for the obsolete KB16SKW01-5F12-AB based on functional equivalence across all critical electrical and mechanical parameters. The substitute part offers enhanced performance characteristics, including 3x current capacity (3A vs. 1A) and doubled mechanical and electrical lifecycle ratings (200,000 and 100,000 cycles respectively).

Selection of the YB16SKW01-5F12-AB is appropriate for applications requiring the KB16SKW01-5F12-AB specification. The increased current rating provides additional design margin without compromising compatibility. The active product status of the YB16SKW01-5F12-AB ensures ongoing availability and supply chain continuity.

Physical integration requires accommodation of the larger panel cutout diameter (16.00mm vs. 12.30mm). Termination style differences (Quick Connect vs. Solder Lug) necessitate circuit board or harness modification. Both components maintain identical voltage ratings, temperature operating range, and illumination specifications.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5F12-AB directly replace the KB16SKW01-5F12-AB without circuit modification?

A: Electrical substitution is direct. The YB16SKW01-5F12-AB maintains identical voltage ratings (125V AC, 30V DC), circuit configuration (SPDT), and illumination specifications (LED, Green, 12VDC). Termination style differs (Quick Connect vs. Solder Lug), requiring connection method adaptation. Panel cutout diameter increase (16.00mm vs. 12.30mm) requires mechanical accommodation in the host panel.

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

A: The KB16SKW01-5F12-AB is rated for 1A maximum continuous current. The YB16SKW01-5F12-AB supports 3A, providing enhanced capacity for the same voltage and circuit configuration. This represents improved performance margin and does not create compatibility issues in applications designed for 1A operation.

Q: Are there compatibility concerns with the panel cutout diameter increase?

A: The YB16SKW01-5F12-AB requires a 16.00mm circular cutout compared to the KB16SKW01-5F12-AB requirement of 12.30mm. Existing panel designs must be evaluated for mechanical accommodation. If the original cutout cannot be enlarged, alternative mounting solutions or panel redesign may be necessary.

Q: How do the lifecycle ratings affect component selection?

A: The YB16SKW01-5F12-AB provides 200,000 mechanical cycles and 100,000 electrical cycles, compared to 100,000 and 50,000 cycles respectively for the KB16SKW01-5F12-AB. Enhanced lifecycle ratings extend component service life and reduce replacement frequency in high-cycle applications.

Q: What is the impact of the product status difference (Obsolete vs. Active)?

A: The KB16SKW01-5F12-AB is obsolete, indicating discontinued manufacturing and limited remaining inventory. The YB16SKW01-5F12-AB maintains active status, ensuring continued manufacturing, availability, and supply chain support for new designs and ongoing production requirements.

Q: Are illumination specifications identical between the two parts?

A: Yes. Both components feature LED illumination in green color at 12VDC nominal voltage. Illumination performance and electrical requirements are equivalent.
