Engineering Selection Recommendations
The FAN6100QMPX is classified as obsolete, making the FAN6290QFMX the identified substitute for ongoing production and new design implementations. The FAN6290QFMX maintains active product status with Fairchild Semiconductor, ensuring continued availability and supply chain stability.
Both components share identical input voltage specifications (up to 16V) and operating temperature ranges (-40°C ~ 125°C), establishing electrical compatibility for secondary-side controller applications. Both devices carry EAR99 export classification and fall under HTSUS code 8542.39.0001.
Key differences exist in supply voltage specifications and package configurations. The FAN6290QFMX operates at 16V supply voltage compared to the FAN6100QMPX range of 3.12V ~ 6V. The FAN6290QFMX utilizes a 10-SOP package versus the 20-WFQFN package of the original component. Current consumption differs, with the FAN6290QFMX drawing 8 mA compared to 2.4 mA for the FAN6100QMPX.
Selection of the FAN6290QFMX requires verification that the application circuit design accommodates the higher supply voltage specification and increased current consumption, along with PCB layout modifications to accommodate the different package footprint.
Frequently Asked Questions (FAQ)
Q: Can the FAN6290QFMX directly replace the FAN6100QMPX without circuit modifications?
A: Direct replacement is not possible due to differences in supply voltage specifications and package configurations. The FAN6290QFMX requires 16V supply voltage versus the FAN6100QMPX specification of 3.12V ~ 6V. PCB layout changes are necessary to accommodate the different package footprint (10-SOP versus 20-WFQFN).
Q: What are the critical parameters for determining substitution compatibility?
A: Substitution compatibility is determined by input voltage specifications (both support up to 16V), operating temperature range (-40°C ~ 125°C for both), functional category (Power Management PMIC), and secondary-side controller application capability. Package and supply voltage differences require circuit-level evaluation.
Q: Why is the FAN6100QMPX classified as obsolete?
A: The FAN6100QMPX is listed as obsolete by onsemi. The FAN6290QFMX maintains active status with Fairchild Semiconductor, providing continued availability for new designs and production requirements.
Q: Are there compliance differences between these components?
A: Both components carry identical ECCN classification (EAR99) and HTSUS codes (8542.39.0001). Both are RoHS3 compliant and REACH unaffected, establishing regulatory equivalence for procurement and deployment.
Q: What design considerations apply when transitioning from FAN6100QMPX to FAN6290QFMX?
A: Design considerations include accommodation of the 16V supply voltage requirement, evaluation of 8 mA current consumption versus 2.4 mA, and PCB layout redesign for the 10-SOP package footprint. Functional verification of secondary-side controller and synchronous rectifier operation within the application circuit is required.
