Substitute Part Grouping Explanation
Substitution of the BAW62,113 is determined by the following critical electrical and mechanical parameters:
Primary Substitution Criteria:
- Voltage - DC Reverse (Vr) rating must equal or exceed 75 V
- Current - Average Rectified (Io) rating must equal or exceed 250 mA
- Mounting type must be through-hole
- Package must be compatible with DO-204AH, DO-35, or axial configurations
- Operating temperature range must accommodate application requirements
Secondary Compatibility Factors:
- Reverse recovery time (trr) and speed classification affect switching performance
- Forward voltage (Vf) characteristics influence power dissipation
- Reverse leakage current affects circuit performance in high-impedance applications
Substitute parts are grouped into two categories based on current rating capacity:
Category A: Full Current Rating (200 mA or higher) Parts meeting or exceeding the 250 mA requirement: 1N4148, 1N4148-1, 1N4149, 1N4150-1, 1N4151, 1N4446, 1N4448, 1N4454
Category B: Reduced Current Rating (150 mA) Parts with lower current capacity suitable for applications with reduced current demands: 1N4148-G, 1N4153-1

Engineering Selection Recommendations
Primary Substitutes (Recommended for New Designs):
1N4149 (Microchip Technology) and 1N4454 (Microchip Technology) are the preferred substitutes. Both parts maintain the 75 V reverse voltage rating, provide 200 mA average rectified current, feature 4 ns reverse recovery time matching the original specification, and are classified as active products with established supply chains. These parts are suitable for applications where the 250 mA rating of the BAW62,113 can be reduced to 200 mA without functional impact.
1N4151 (Microchip Technology) offers superior reverse recovery performance at 2 ns and maintains 75 V / 200 mA ratings, making it suitable for high-speed switching applications. However, RoHS non-compliance status must be evaluated against project requirements.
Secondary Substitutes (Conditional Use):
1N4148-1 (Microchip Technology) provides exact voltage matching (75 V) and acceptable current rating (200 mA) but exhibits extended reverse recovery time (20 ns), which may impact switching speed-dependent circuits. This part is active and available.
1N4446 (Microchip Technology) and 1N4448 (Microchip Technology) both meet electrical specifications with 75 V / 200 mA ratings and 4 ns recovery time. 1N4448 is discontinued at DiGi Electronics, limiting long-term availability.
Voltage-Reduced Alternatives (Lower Voltage Applications Only):
1N4150-1 (Microchip Technology) and 1N4153-1 (Microchip Technology) feature reduced 50 V reverse voltage ratings. These parts are suitable only for applications where the circuit voltage does not exceed 50 V, as they do not meet the 75 V specification of the original part.
Compliance Considerations:
The BAW62,113 is ROHS3 compliant. Most active substitute parts (1N4149, 1N4151, 1N4446, 1N4448, 1N4454) are RoHS non-compliant. For projects requiring RoHS3 compliance, 1N4148 (Taiwan Semiconductor) and 1N4148-G (Comchip Technology) are compliant alternatives, though 1N4148-G is obsolete and 1N4148 provides only 150 mA current rating.
Frequently Asked Questions (FAQ)
Q: Can the 1N4148 directly replace the BAW62,113?
A: The 1N4148 is electrically compatible in terms of voltage (100 V rating exceeds the 75 V requirement) and package (DO-35 through-hole). However, the 1N4148 provides only 150 mA average rectified current, which is below the BAW62,113's 250 mA rating. Substitution is valid only if the application circuit operates at 150 mA or lower. The 1N4148 is active and widely available.
Q: What is the difference between 1N4149 and 1N4454?
A: Both parts share identical electrical specifications: 75 V reverse voltage, 200 mA average rectified current, 4 ns reverse recovery time, and DO-35 through-hole package. Both are active products from Microchip Technology. Selection between these parts depends on availability and supplier preference, as they are functionally equivalent for the BAW62,113 application.
Q: Why do some substitutes have lower current ratings (150 mA vs. 250 mA)?
A: The BAW62,113 is rated for 250 mA, but many modern equivalent parts are rated for 200 mA or 150 mA. These lower ratings reflect current manufacturing standards and design practices. Substitution with lower-rated parts is valid if the actual circuit current does not exceed the substitute part's rating. Circuit analysis must confirm that peak and average currents remain within the substitute part's specifications.
Q: Are all substitute parts through-hole mounted?
A: Yes. All substitute parts listed maintain through-hole mounting in DO-35 or DO-204AH axial packages, ensuring mechanical compatibility with the BAW62,113's footprint and assembly process.
Q: What does "RoHS non-compliant" mean for these diodes?
A: RoHS non-compliance indicates the part may contain restricted substances such as lead. For applications subject to RoHS3 regulations (primarily European Union markets), only ROHS3-compliant parts such as 1N4148 or 1N4148-G are acceptable. For unrestricted applications, RoHS non-compliant parts present no functional limitation.
Q: Can I use 1N4150-1 or 1N4153-1 as substitutes?
A: These parts feature 50 V reverse voltage ratings, which is below the BAW62,113's 75 V specification. They are suitable only for applications where the circuit voltage does not exceed 50 V. Using these parts in circuits designed for 75 V operation will result in diode failure due to reverse voltage overstress.
Q: What is reverse recovery time (trr) and why does it matter?
A: Reverse recovery time is the interval required for a diode to stop conducting after the applied voltage reverses. The BAW62,113 specifies 4 ns. Substitute parts with longer trr values (such as 1N4148-1 at 20 ns) may introduce switching delays in high-frequency circuits. For general-purpose rectification, trr differences are typically non-critical.
Q: Is the BAW62,113 still available for purchase?
A: The BAW62,113 is classified as obsolete. While 929 pieces are reported in stock, long-term availability is not guaranteed. Active substitute parts such as 1N4149 and 1N4454 are recommended for new designs to ensure supply continuity.
