Parameter Comparison

Engineering Selection Recommendations

The BFR460L3E6327XTMA1 is the qualified substitute for the discontinued BFS 466L6 E6327 based on the following factors:

Product Availability: The BFR460L3E6327XTMA1 maintains Active product status with 15,872 pieces in stock, ensuring supply chain continuity for production requirements.

Compliance and Certification: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, satisfying environmental and moisture sensitivity requirements. Both are REACH Unaffected and classified as EAR99 for export control purposes.

Electrical Performance: The substitute part meets or exceeds all critical electrical parameters. The 5.8V Collector-Emitter breakdown voltage accommodates the original 5V and 9V operating points. The 22GHz transition frequency matches the primary frequency specification of the original part. Noise figure, gain, power dissipation, and current gain specifications are equivalent or superior.

Functional Equivalence: While the BFR460L3E6327XTMA1 is a single NPN transistor compared to the dual NPN configuration of the original part, it provides equivalent RF performance for applications requiring single transistor operation or where dual transistors can be implemented using two discrete components.

Frequently Asked Questions (FAQ)

Q: Can the BFR460L3E6327XTMA1 directly replace the BFS 466L6 E6327 in all applications?

A: The BFR460L3E6327XTMA1 is electrically equivalent for single NPN transistor applications. Applications utilizing the dual transistor configuration of the BFS 466L6 E6327 require circuit redesign to accommodate two discrete BFR460L3E6327XTMA1 components or alternative dual transistor packages.

Q: What are the package differences between these parts?

A: The BFS 466L6 E6327 uses TSLP-6-1 packaging (6-XFDFN case), while the BFR460L3E6327XTMA1 uses PG-TSLP-3-1 packaging (SC-101, SOT-883 case). Both are surface mount packages suitable for automated assembly, but PCB layout modifications are required due to different pin configurations and footprints.

Q: Are there frequency limitations when substituting?

A: No. The BFR460L3E6327XTMA1 operates at 22GHz transition frequency, matching the maximum frequency specification of the original part. Applications operating at 14GHz are fully supported.

Q: What is the impact of the voltage rating difference (5.8V vs. 5V/9V)?

A: The 5.8V rating of the substitute part is sufficient for 5V operation with adequate margin. For 9V applications, circuit design must ensure the transistor operates within the 5.8V Collector-Emitter breakdown limit through appropriate biasing and load impedance selection.

Q: Are there current handling differences?

A: The BFR460L3E6327XTMA1 supports 50mA maximum collector current, matching the higher rating of the original dual transistor configuration. This provides equivalent current handling capability for single transistor applications.

Q: What certifications apply to the substitute part?

A: The BFR460L3E6327XTMA1 maintains ROHS3 compliance, MSL 1 (Unlimited) rating, REACH Unaffected status, and EAR99 export classification, identical to the original part.
