Substitute Part Grouping Explanation
Substitution of the BAS 16 B5003 is determined by the following critical parameters: DC reverse voltage rating, average rectified current capacity, forward voltage characteristics, recovery speed classification, and package compatibility. Parts are grouped into three categories based on substitution relationship:
Parametric Equivalents maintain all electrical specifications and package form factor, differing only in packaging format (Cut Tape, Tape & Reel, or Bulk). These parts are direct functional replacements with identical performance characteristics.
Manufacturer Recommended Substitutes provide functional alternatives from different manufacturers with comparable electrical performance. These parts may exhibit minor variations in reverse leakage current, recovery time, or current rating while maintaining compatibility with the original application requirements.
Acceptable Substitutes operate within the electrical envelope of the original part but may have different voltage ratings, current ratings, or speed classifications. Selection of these parts requires verification that the application can tolerate the parameter variations.
The critical parameters determining substitution eligibility are:
- DC Reverse Voltage (Vr): Must equal or exceed 80 V
- Average Rectified Current (Io): Must equal or exceed 250 mA
- Forward Voltage (Vf): Must not exceed 1.25 V @ 150 mA
- Speed Classification: Fast Recovery preferred for equivalent performance
- Package: TO-236-3, SC-59, or SOT-23-3 surface mount only
- Mounting Type: Surface Mount required

Frequently Asked Questions (FAQ)
Q: Can BAS16E6327HTSA1 or BAS16E6433HTMA1 be used as direct replacements for BAS 16 B5003?
A: Yes. Both parts are parametric equivalents with identical electrical specifications: 80 V reverse voltage, 250 mA average rectified current, 1.25 V forward voltage at 150 mA, and 4 ns recovery time. The only differences are packaging format (Cut Tape versus Tape & Reel) and product status (Last Time Buy). Both are compatible with the original SOT-23-3 package footprint.
Q: What is the difference between fast recovery and standard recovery diodes?
A: Recovery speed refers to the reverse recovery time (trr), which is the time required for a diode to switch from forward conduction to reverse blocking. Fast recovery diodes have trr ≤ 500 ns and are suitable for high-frequency switching applications. Standard recovery diodes have trr > 500 ns and are suitable for lower-frequency applications. The BAS 16 B5003 specifies fast recovery with 4 ns trr. Substitutes with standard recovery (such as BAS116 series at 3 µs) are acceptable only if the application does not require fast switching performance.
Q: Can I use BAS16,215 or BAS16,235 as replacements for BAS 16 B5003?
A: BAS16,215 and BAS16,235 are acceptable substitutes with important considerations. Both parts maintain the 80 V reverse voltage specification of the original part and exceed it at 100 V. However, the average rectified current rating is reduced from 250 mA to 215 mA. These parts are suitable for applications where the circuit current does not exceed 215 mA. Both maintain fast recovery performance with 4 ns recovery time and identical forward voltage characteristics. Both parts are Active status with high inventory availability.
Q: What is the significance of the voltage rating difference between BAS 16 B5003 (80 V) and BAS16,215 (100 V)?
A: A higher voltage rating provides additional safety margin in the circuit. If the original design operates at voltages below 80 V, using a 100 V rated diode is acceptable and provides improved reliability. However, if the application specifically requires a diode rated for exactly 80 V or lower, the higher voltage rating does not present a problem. The forward voltage and recovery characteristics remain identical.
Q: Are there automotive-qualified alternatives available?
A: Yes. BAS16,215 from Nexperia USA Inc. carries AEC-Q101 automotive qualification and is available in high volume. BAS116,215 and BAS116,235 from Nexperia USA Inc. carry AEC-Q100 automotive qualification. These parts are suitable for automotive applications requiring qualified components.
Q: What packaging formats are available for the substitute parts?
A: Substitute parts are available in multiple packaging formats: Cut Tape (CT), Tape & Reel (TR), Bulk, and Digi-Reel®. The choice of packaging format depends on production volume and assembly equipment compatibility. All substitute parts maintain the same SOT-23-3 surface mount package footprint, ensuring mechanical compatibility with the original design.
Q: Can BAS116LT1G or BAS16-G be used as replacements?
A: BAS116LT1G and BAS16-G are acceptable substitutes with reduced performance specifications. Both parts are rated for 75 V reverse voltage (below the original 80 V) and 200 mA average rectified current (below the original 250 mA). Both are classified as small signal diodes with standard recovery characteristics. These parts are suitable only for applications where the circuit voltage does not exceed 75 V and current does not exceed 200 mA. Both parts are Active status with good inventory availability.
Q: What is the difference between BAS16-7-F and BAS16-TP?
A: BAS16-7-F from Diodes Incorporated is rated for 75 V reverse voltage and 300 mA average rectified current with fast recovery (4 ns). BAS16-TP from Micro Commercial Co is rated for 100 V reverse voltage and 300 mA average rectified current with fast recovery (4 ns). BAS16-TP provides higher voltage margin and is suitable for applications requiring 100 V rating. BAS16-7-F is suitable for applications operating at 75 V or below. Both parts maintain fast recovery performance and are Active status.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed carry ROHS3 compliance status. All parts also carry REACH Unaffected status, indicating compliance with European chemical regulations.
Q: What is the Moisture Sensitivity Level (MSL) for these parts?
A: All parts, including the original BAS 16 B5003 and all substitute parts, carry MSL 1 (Unlimited) rating. This indicates the parts have unlimited shelf life and do not require special moisture control during storage or handling.
