Engineering Selection Recommendations

For Standard Applications: The HER107G A0G, UF1K A0G, UF4006 A0G, and UF4006-E3/73 are direct parametric equivalents with active product status. These parts maintain identical electrical specifications and through-hole DO-41 package compatibility. The UF4006-E3/73 offers the highest inventory availability (23,300 pcs) and is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes.

For Automotive Applications: The UF1KHA0G and UF4006HA0G are qualified to AEC-Q101 automotive standards and maintain all electrical parameters of the UF4006GP-AP. These parts are appropriate for applications requiring automotive-grade component certification.

For Legacy System Support: All listed substitutes are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original UF4006GP-AP. The transition from the obsolete UF4006GP-AP to any active substitute part does not introduce compliance or regulatory barriers.

Reverse Leakage Consideration: Vishay parts (UF4006-E3/53, UF4006-E3/73, UF4006-M3/73) specify 10 µA reverse leakage at 800 V, compared to 5 µA for Taiwan Semiconductor Corporation parts. This difference remains within acceptable limits for general-purpose rectification applications and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can I directly replace UF4006GP-AP with HER107G A0G? A: Yes. Both parts share identical electrical specifications: 800 V reverse voltage, 1 A average rectified current, 1.7 V forward voltage at 1 A, and 75 ns reverse recovery time. Both use through-hole DO-41 packaging and are ROHS3 compliant.

Q: What is the difference between UF4006-E3/73 and UF4006-E3/53? A: Both are manufactured by Vishay and share identical electrical parameters. The primary difference is packaging: UF4006-E3/73 is supplied in Cut Tape (CT) with significantly higher inventory (23,300 pcs), while UF4006-E3/53 is supplied in Tape & Box (TB) with lower inventory (858 pcs). Electrical performance is identical.

Q: Should I use UF1KHA0G or UF4006HA0G for automotive applications? A: Both parts are AEC-Q101 qualified and suitable for automotive use. UF4006HA0G is the automotive-grade variant of the UF4006 base product number, while UF1KHA0G is the automotive-grade variant of the UF1K base product number. Selection depends on your design's existing part number references.

Q: Why do some substitutes show 10 µA reverse leakage instead of 5 µA? A: Vishay General Semiconductor parts (UF4006-E3/53, UF4006-E3/73, UF4006-M3/73) specify 10 µA reverse leakage at 800 V, while Taiwan Semiconductor Corporation parts specify 5 µA. Both values are within acceptable limits for general-purpose rectifier applications and do not affect functional compatibility or circuit performance.

Q: Is the DO-204AL package identical to DO-41? A: Yes. DO-204AL and DO-41 are equivalent designations for the same axial through-hole package. All substitute parts use this package type and are mechanically compatible with the original UF4006GP-AP.

Q: Can I use these substitutes in new designs? A: Yes. All listed substitute parts have Active product status, making them suitable for new designs. The original UF4006GP-AP is marked "Not For New Designs," but all substitutes are actively manufactured and supported by their respective suppliers.

Q: Are all substitutes RoHS3 compliant? A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance profile of the UF4006GP-AP.
