Key Parameters

Substitute Part Grouping Explanation

The YB15CKW01-GB qualifies as a substitute for the KB15CKW01-GG based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Voltage rating - AC: 125V
• Voltage rating - DC: 30V
• Mounting type: Panel Mount, Front
• Actuator type: Round, Button
• Operating temperature range: -25°C to 70°C
• RoHS compliance: ROHS3 Compliant
• REACH status: REACH Unaffected

Differing Parameters Requiring Evaluation:

• Current rating: YB15CKW01-GB rated at 3A versus KB15CKW01-GG at 1A
• Panel cutout diameter: YB15CKW01-GB requires 16.00mm versus KB15CKW01-GG at 12.30mm
• Mechanical life: YB15CKW01-GB rated at 1,000,000 cycles versus KB15CKW01-GG at 100,000 cycles
• Electrical life: YB15CKW01-GB rated at 100,000 cycles versus KB15CKW01-GG at 50,000 cycles
• Termination style: YB15CKW01-GB uses Solder and Quick Connect versus KB15CKW01-GG Solder Lug only
• Product status: YB15CKW01-GB is Active

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-GB is available as an active product from NKK Switches and maintains ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the obsolete KB15CKW01-GG. The substitute part provides enhanced electrical and mechanical performance characteristics, including higher current capacity (3A versus 1A) and extended operational life ratings (1,000,000 mechanical cycles versus 100,000).

Physical integration requires panel cutout modification from 12.30mm to 16.00mm diameter. Termination compatibility must be verified, as the YB15CKW01-GB offers both solder and quick connect options, whereas the KB15CKW01-GG uses solder lug termination exclusively. Both parts maintain identical voltage ratings, temperature operating range, and circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can YB15CKW01-GB directly replace KB15CKW01-GG without circuit modifications?

A: Electrical compatibility is maintained across voltage ratings (125V AC, 30V DC), circuit configuration (SPDT), and switch function (On-Mom). However, panel cutout diameter differs (16.00mm versus 12.30mm), requiring mechanical panel modification. Termination style differences must be addressed during integration.

Q: What is the impact of the higher current rating on the YB15CKW01-GB?

A: The YB15CKW01-GB is rated for 3A versus the KB15CKW01-GG at 1A. This higher rating provides additional design margin for applications operating at or near the original 1A specification and does not create incompatibility for lower-current applications.

Q: Are there packaging differences between these parts?

A: The KB15CKW01-GG is supplied in standard packaging, while the YB15CKW01-GB is supplied in Tray packaging. This affects procurement and handling procedures but does not impact component functionality.

Q: How do the mechanical and electrical life ratings compare?

A: The YB15CKW01-GB provides significantly extended operational life: 1,000,000 mechanical cycles and 100,000 electrical cycles compared to 100,000 mechanical cycles and 50,000 electrical cycles for the KB15CKW01-GG. This represents a 10-fold improvement in mechanical life and a 2-fold improvement in electrical life.

Q: What termination options are available with the substitute part?

A: The YB15CKW01-GB offers both Solder and Quick Connect (0.110" / 2.8mm) termination options, providing flexibility beyond the solder lug termination of the KB15CKW01-GG. Circuit design must accommodate the selected termination method.
