Key Parameters

Substitute Part Grouping Explanation

The YB15CKG01-6B-JB qualifies as a functional equivalent based on the following matching parameters: identical SPDT circuit configuration, matching 0.4VA current rating at 28V AC/DC, equivalent panel mount front-facing installation, identical LED white illumination at 3.3VDC, matching round button actuator type, and identical operating temperature range of -25°C to 50°C. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitution is valid where the following differences are acceptable to the application: YB15CKG01-6B-JB features enhanced mechanical life (1,000,000 cycles versus 100,000 cycles), stainless steel construction, larger panel cutout diameter (16.00mm versus 12.30mm), and alternative termination style (Solder, Quick Connect - 0.110" versus Solder Lug). The YB series part carries active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKG01-6B-JB is the designated equivalent for KB15CKG01-6B-JB applications. Selection of the YB series substitute is supported by: active product status ensuring long-term availability and supply chain continuity, identical electrical and switching specifications matching the original design requirements, enhanced mechanical durability (1,000,000 cycle rating), and maintained ROHS3 and REACH compliance certifications.

Implementation of YB15CKG01-6B-JB requires panel cutout modification from 12.30mm to 16.00mm diameter and termination interface adaptation from solder lug to quick connect 0.110" (2.8mm) configuration. These mechanical and termination changes must be evaluated within the context of the specific application's panel design and circuit board layout.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substitution between KB15CKG01-6B-JB and YB15CKG01-6B-JB?

A: The following electrical parameters are identical and ensure functional compatibility: SPDT circuit configuration, 0.4VA current rating at 28V AC/DC, LED white illumination at 3.3VDC nominal voltage, and On-Mom switch function. Both parts operate across the identical temperature range of -25°C to 50°C.

Q: What are the mechanical differences between these parts?

A: The primary mechanical differences are panel cutout diameter (KB series: 12.30mm; YB series: 16.00mm) and termination style (KB series: Solder Lug; YB series: Solder with Quick Connect - 0.110" / 2.8mm). The YB series also incorporates stainless steel construction and provides 10x greater mechanical life rating (1,000,000 versus 100,000 cycles).

Q: Can YB15CKG01-6B-JB be used as a direct drop-in replacement?

A: Direct installation is not possible without panel modification and termination interface adaptation. The larger panel cutout diameter of the YB series requires enlargement of the mounting hole from 12.30mm to 16.00mm. The termination style change from solder lug to quick connect requires circuit board layout adjustment.

Q: Are both parts compliant with current regulatory standards?

A: Both KB15CKG01-6B-JB and YB15CKG01-6B-JB maintain ROHS3 compliance and REACH unaffected status. The YB series part carries active product status, ensuring ongoing compliance maintenance and regulatory support.

Q: Why is the KB series listed as obsolete?

A: The KB15CKG01-6B-JB is classified as obsolete, indicating discontinued manufacturing and limited remaining inventory (959 pieces). The YB15CKG01-6B-JB represents the active equivalent offering, with 967 pieces currently in stock and ongoing production support from NKK Switches.
