Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB25RKW01-6G-JB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (DPDT)
• Switch function (On-Mom)
• Voltage rating - AC (125V minimum)
• Voltage rating - DC (30V minimum)
• Mounting type (Panel Mount, Front)
• Illumination type and color (LED, Blue)
• Illumination voltage (3.6VDC nominal)
• Operating temperature range (-25°C to 50°C minimum)
• RoHS compliance status (ROHS3)

Allowable Variation Parameters:

• Current rating (must equal or exceed 1A)
• Mechanical life (must equal or exceed 100,000 cycles)
• Electrical life (must equal or exceed 50,000 cycles)
• Panel cutout diameter (mechanical accommodation required)
• Termination style (application-dependent)

The substitute part YB25RKW01-6G-JB meets all mandatory matching criteria while providing enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB25RKW01-6G-JB is a direct functional substitute for the obsolete KB25RKW01-6G-JB. Both components maintain identical electrical specifications for voltage and circuit configuration, ensuring compatibility in existing circuit designs. The substitute part is currently in active production status, providing supply chain continuity and long-term availability.

The YB25RKW01-6G-JB offers enhanced performance characteristics with a 3A current rating versus the original 1A specification, providing increased design margin for applications requiring higher switching capacity. Mechanical and electrical life ratings are substantially improved, extending component service life and reducing maintenance intervals.

Both components maintain ROHS3 compliance and identical operating temperature specifications. The substitute part features voltage reduction lighting capability and an expanded panel cutout diameter of 16.00mm compared to the original 12.30mm specification. Panel mounting accommodation must be verified for the larger cutout dimension.

Frequently Asked Questions (FAQ)

Q: Can YB25RKW01-6G-JB directly replace KB25RKW01-6G-JB in existing designs?

A: Yes, the YB25RKW01-6G-JB provides functional equivalence for circuit operation. The DPDT configuration, On-Mom function, voltage ratings, and LED illumination specifications are identical. Panel cutout diameter differences require mechanical verification.

Q: What is the primary difference between these two parts?

A: The substitute part provides a higher current rating (3A versus 1A), extended mechanical life (1,000,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles). The substitute is in active production while the original is obsolete.

Q: Are there termination style differences?

A: Yes. The KB25RKW01-6G-JB uses solder lug termination, while the YB25RKW01-6G-JB offers solder and quick connect 0.110" (2.8mm) termination options. Application requirements determine appropriate termination selection.

Q: Does the larger panel cutout diameter affect compatibility?

A: The YB25RKW01-6G-JB requires a 16.00mm circular panel cutout versus 12.30mm for the original part. Existing panel designs must accommodate this dimensional change or require mechanical modification.

Q: Are both parts RoHS compliant?

A: Yes, both KB25RKW01-6G-JB and YB25RKW01-6G-JB are ROHS3 compliant and REACH unaffected.
