Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-GG is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT
• Switch Function: On-Mom (Momentary)
• Voltage Rating - AC: 125V
• Voltage Rating - DC: 30V
• Mounting Type: Panel Mount, Front
• Actuator Type: Square, Button
• Operating Temperature Range: -25°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current Rating: May be equal to or greater than 1A
• Mechanical Life: May be equal to or greater than 100,000 cycles
• Electrical Life: May be equal to or greater than 50,000 cycles
• Panel Cutout Dimensions: Circular aperture diameter may vary within mechanical design constraints
• Termination Style: Alternative termination methods acceptable if electrical connection integrity is maintained
• Product Status: Active status preferred for ongoing availability

The YB15SKW01-GB meets all mandatory matching parameters while exceeding performance specifications in current rating (3A vs 1A), mechanical life (1,000,000 vs 100,000 cycles), and electrical life (100,000 vs 50,000 cycles). Panel cutout dimension increase (16.00mm vs 12.30mm) requires mechanical design verification.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-GB is a valid substitute for the KB15SKW01-GG based on electrical and functional equivalence. Both components are ROHS3 compliant and maintain identical voltage ratings, circuit configuration, and operating temperature specifications.

The substitute part offers enhanced performance characteristics with higher current capacity (3A vs 1A) and extended mechanical and electrical life ratings. These improvements provide additional design margin for applications where the original KB15SKW01-GG was specified.

The primary design consideration is the panel cutout dimension increase from 12.30mm to 16.00mm diameter. Mechanical integration requires verification that the larger aperture is compatible with existing panel designs. The termination style change from solder lug to solder with quick connect option provides flexibility in circuit board integration.

The active product status of YB15SKW01-GB ensures ongoing availability and supply chain continuity compared to the obsolete KB15SKW01-GG.

Frequently Asked Questions (FAQ)

Q: Can YB15SKW01-GB directly replace KB15SKW01-GG in existing designs?

A: Electrical substitution is valid. Mechanical integration requires panel cutout verification due to the 16.00mm diameter requirement versus the original 12.30mm specification. Termination compatibility must be confirmed for circuit board connection methods.

Q: What are the key electrical differences between these parts?

A: Both parts maintain identical SPDT circuit configuration, 125V AC and 30V DC voltage ratings, and -25°C to 70°C operating temperature range. The YB15SKW01-GB provides higher current capacity (3A versus 1A) and extended life ratings (1,000,000 mechanical cycles versus 100,000; 100,000 electrical cycles versus 50,000).

Q: Is the higher current rating of YB15SKW01-GB a concern for low-current applications?

A: No. Higher current rating does not negatively impact low-current circuit operation. The 3A rating of the substitute provides additional design margin and does not affect switching characteristics for 1A applications.

Q: What is the impact of the panel cutout dimension change?

A: The increase from 12.30mm to 16.00mm diameter requires mechanical design review. Panel drilling or cutout modification may be necessary. This is a mechanical integration consideration, not an electrical limitation.

Q: Are both parts RoHS compliant?

A: Yes. Both KB15SKW01-GG and YB15SKW01-GB are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the difference in termination style?

A: KB15SKW01-GG uses solder lug termination. YB15SKW01-GB offers both solder and quick connect 0.110" (2.8mm) termination options. Circuit board connection method compatibility must be verified during integration.
