Substitute Part Grouping Explanation

Substitute parts for the BAS40L2-TP are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical or superior electrical specifications across all critical parameters: 40 V reverse voltage rating, 200 mA average rectified current, 1 V forward voltage at 40 mA, 5 ns reverse recovery time, and 200 nA reverse leakage current at 30 V. These parts are mechanically compatible within the 0402 (1006 Metric) package family and operate across the same temperature range (-55°C to 125°C). Parametric equivalents include ACDBQC40-HF and BAS40LP-7.

Similar Substitutes provide reduced electrical ratings suitable for applications with lower voltage or current requirements. The NSR0140P2T5G operates at 30 V reverse voltage and 70 mA average rectified current, representing a downrated alternative. This part is compatible only in circuits where the reduced voltage and current specifications are acceptable.

All substitute parts maintain Schottky technology classification, surface mount mounting type, RoHS3 compliance, and MSL 1 rating, ensuring regulatory and environmental compatibility with the primary part.

Parameter Comparison

Engineering Selection Recommendations

ACDBQC40-HF (Comchip Technology) is a parametric equivalent suitable for direct substitution in applications requiring 40 V reverse voltage and 200 mA average rectified current. This part maintains identical electrical specifications to the BAS40L2-TP, including forward voltage, reverse recovery time, and reverse leakage current. The ACDBQC40-HF carries AEC-Q101 automotive qualification, providing additional reliability assurance for automotive and industrial applications. Both parts are packaged in 0402 (1006 Metric) format and are RoHS3 compliant with MSL 1 rating.

BAS40LP-7 (Diodes Incorporated) is a parametric equivalent offering identical voltage and current ratings with marginally lower capacitance (2.3 pF versus 5 pF at 0V, 1MHz). This part is suitable for direct substitution where reduced parasitic capacitance may provide performance benefits in high-frequency switching applications. The BAS40LP-7 is packaged in X1-DFN1006-2 format, mechanically compatible with the 0402 (1006 Metric) package family. All electrical and compliance specifications align with the primary part.

NSR0140P2T5G (onsemi) is a similar substitute with reduced electrical ratings: 30 V reverse voltage and 70 mA average rectified current. This part is suitable only for applications where the lower voltage and current specifications are acceptable. The NSR0140P2T5G is packaged in SOD-923 format, which differs from the 0402 (1006 Metric) package of the primary part and requires PCB layout modification. Selection of this part is appropriate for cost optimization in lower-power circuit designs.

All substitute parts maintain Active product status and full RoHS3 compliance, ensuring regulatory compatibility and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can ACDBQC40-HF replace BAS40L2-TP in all applications?

A: Yes. ACDBQC40-HF is a parametric equivalent with identical voltage (40 V), current (200 mA), forward voltage (1 V @ 40 mA), reverse recovery time (5 ns), and reverse leakage current (200 nA @ 30 V) specifications. Both parts use 0402 (1006 Metric) packaging and operate across -55°C to 125°C. Direct substitution is supported without circuit modification.

Q: What is the difference between BAS40LP-7 and BAS40L2-TP?

A: BAS40LP-7 is a parametric equivalent with identical electrical ratings. The primary difference is capacitance: BAS40LP-7 measures 2.3 pF at 0V, 1MHz compared to 5 pF for BAS40L2-TP. This lower capacitance may provide performance advantages in high-frequency switching circuits. Both parts are packaged in compatible 0402 (1006 Metric) formats.

Q: When should NSR0140P2T5G be selected as a substitute?

A: NSR0140P2T5G is suitable only for applications where reduced electrical specifications are acceptable: 30 V reverse voltage (versus 40 V) and 70 mA average rectified current (versus 200 mA). This part is appropriate for cost optimization in lower-power designs. PCB layout modification is required due to SOD-923 packaging, which differs from the 0402 (1006 Metric) package of the primary part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ACDBQC40-HF, BAS40LP-7, and NSR0140P2T5G are all RoHS3 compliant with MSL 1 (Unlimited) rating, matching the compliance profile of BAS40L2-TP.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across -55°C to 125°C junction temperature, identical to the BAS40L2-TP primary part.

Q: Does ACDBQC40-HF include automotive qualification?

A: Yes. ACDBQC40-HF carries AEC-Q101 automotive qualification and Automotive grade designation, providing additional reliability assurance for automotive applications. BAS40L2-TP, BAS40LP-7, and NSR0140P2T5G do not specify automotive qualification.

Q: Can BAS40LP-7 be used in high-frequency applications?

A: BAS40LP-7 may provide performance benefits in high-frequency switching applications due to lower capacitance (2.3 pF versus 5 pF). However, selection should be based on specific circuit requirements and frequency of operation.

Q: What packaging considerations apply when selecting NSR0140P2T5G?

A: NSR0140P2T5G uses SOD-923 packaging, which differs from the 0402 (1006 Metric) package of BAS40L2-TP. PCB layout and footprint modification is required for this substitution. This part is not a direct drop-in replacement.
