Substitute Part Grouping Explanation
Substitute parts for the BAS40-05Q-7-F are classified into two categories based on electrical parameter alignment:
Parametric Equivalents maintain all critical electrical specifications: 40 V DC reverse voltage, 200 mA average rectified current per diode, 1 V forward voltage at 40 mA, 5 ns reverse recovery time, and identical package configuration (SOT-23-3). These parts are direct functional replacements with no circuit redesign required.
Similar Parts share the same diode configuration, technology, current rating, and package but differ in one or more electrical parameters. The BAT54C-HE3-08 operates at a reduced 30 V DC reverse voltage rating, making it suitable only for applications with lower voltage requirements.
Substitution eligibility is determined by:
- Matching diode configuration (1 Pair Common Cathode)
- Matching Schottky technology
- Equal or greater voltage rating (Vr ≥ 40 V for direct substitution)
- Equal or greater current rating (Io ≥ 200 mA)
- Compatible package footprint (SOT-23-3)
- Surface mount mounting type

Engineering Selection Recommendations
Direct Substitutes (Parametric Equivalents):
BAS40-05-7-F, BAS40-05-E3-08, and BAS40-05-TP are parametric equivalents to the BAS40-05Q-7-F. All three maintain the 40 V DC reverse voltage, 200 mA average rectified current, and SOT-23-3 package configuration. These parts are suitable for direct replacement without circuit modification.
BAS40-05-7-F (Diodes Incorporated) and BAS40-05-TP (Micro Commercial Co) are identical to the main part in all specified electrical parameters and operating temperature range (-55°C to 125°C). BAS40-05-7-F offers the highest inventory availability at 47,400 units.
BAS40-05-E3-08 (Vishay General Semiconductor) matches all electrical specifications but specifies a maximum junction temperature of 125°C without a minimum temperature range. This part is suitable for applications where the full -55°C to 125°C range is not required.
Conditional Substitute (Reduced Voltage Rating):
BAT54C-HE3-08 (Vishay General Semiconductor) is a similar part with a reduced 30 V DC reverse voltage rating. This part is suitable only for applications where the circuit operates at 30 V or below. The BAT54C-HE3-08 is in Last Time Buy status, indicating discontinued production. This part also exhibits higher reverse leakage current (2 µA @ 25 V) compared to the main part (200 nA @ 30 V).
Compliance and Qualification:
The BAS40-05Q-7-F and BAT54C-HE3-08 both carry AEC-Q101 automotive qualification. The BAS40-05-7-F, BAS40-05-E3-08, and BAS40-05-TP do not specify AEC-Q101 qualification in the provided data. All parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity.
Packaging Considerations:
The main part and all parametric equivalents are supplied in Tape & Reel (TR) packaging. The BAT54C-HE3-08 is supplied in Cut Tape (CT) & Digi-Reel® packaging, which may require different handling or feeder compatibility in automated assembly processes.
Frequently Asked Questions (FAQ)
Q: Can BAS40-05-7-F be used as a direct replacement for BAS40-05Q-7-F?
A: Yes. BAS40-05-7-F is a parametric equivalent manufactured by Diodes Incorporated with identical electrical specifications: 40 V DC reverse voltage, 200 mA average rectified current, 1 V forward voltage at 40 mA, 5 ns reverse recovery time, and SOT-23-3 package. Both parts operate across -55°C to 125°C. The primary difference is packaging format (both are Tape & Reel) and inventory availability.
Q: Is BAT54C-HE3-08 a suitable substitute?
A: BAT54C-HE3-08 is a similar part but not a direct equivalent. It operates at a reduced 30 V DC reverse voltage rating compared to the 40 V rating of the BAS40-05Q-7-F. Use BAT54C-HE3-08 only in applications where the maximum reverse voltage does not exceed 30 V. Additionally, BAT54C-HE3-08 is in Last Time Buy status and exhibits higher reverse leakage current (2 µA @ 25 V versus 200 nA @ 30 V).
Q: What is the difference between BAS40-05-E3-08 and the main part?
A: BAS40-05-E3-08 is a parametric equivalent manufactured by Vishay General Semiconductor with identical electrical specifications. The specified difference is the operating temperature range: BAS40-05-E3-08 specifies a maximum junction temperature of 125°C without a stated minimum, while the main part specifies -55°C to 125°C. BAS40-05-E3-08 also exhibits lower reverse leakage current (100 nA @ 30 V versus 200 nA @ 30 V).
Q: Can I use BAS40-05-TP as a substitute?
A: Yes. BAS40-05-TP manufactured by Micro Commercial Co is a parametric equivalent with identical electrical specifications and operating temperature range (-55°C to 125°C). The part is supplied in Tape & Reel packaging and is suitable for direct replacement.
Q: What packaging differences exist among the substitute parts?
A: BAS40-05-7-F, BAS40-05-E3-08, and BAS40-05-TP are all supplied in Tape & Reel (TR) packaging, matching the main part. BAT54C-HE3-08 is supplied in Cut Tape (CT) & Digi-Reel® packaging, which may require different feeder compatibility in automated assembly equipment.
Q: Are all substitute parts AEC-Q101 qualified?
A: No. The BAS40-05Q-7-F and BAT54C-HE3-08 are both AEC-Q101 qualified for automotive applications. The parametric equivalents BAS40-05-7-F, BAS40-05-E3-08, and BAS40-05-TP do not specify AEC-Q101 qualification in the provided data. For automotive applications requiring AEC-Q101 qualification, use BAS40-05Q-7-F or BAT54C-HE3-08 (subject to voltage rating compatibility).
Q: Which substitute part has the best inventory availability?
A: BAS40-05-7-F has the highest inventory availability at 47,400 units in stock, compared to 3,431 units for the main part BAS40-05Q-7-F.
Q: Can I substitute BAS40-05-TP in a design that requires -55°C operation?
A: Yes. BAS40-05-TP specifies an operating temperature range of -55°C to 125°C, matching the main part. It is suitable for applications requiring full temperature range operation.
