BAV199 Equivalent & Substitute Parts

Part Overview

The BAV199 is a general-purpose diode array in a 1 Pair Series Connection configuration, rated for 85 V DC reverse voltage and 140 mA average rectified current per diode. The device is packaged in SOT-23-3 (TO-236-3, SC-59) surface mount format and operates across a junction temperature range of -65°C to 150°C. The original BAV199 manufactured by Diodes Incorporated is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design requirements and production needs. Alternative sources and packaging configurations are available from multiple manufacturers, including parametric equivalents and variants with enhanced electrical performance.

Substitute Part Grouping Explanation

Substitution of the BAV199 is determined by electrical and mechanical compatibility across the following critical parameters: diode configuration (1 Pair Series Connection), package type (SOT-23-3 surface mount), reverse voltage rating, average rectified current capacity, forward voltage characteristics, reverse recovery time, reverse leakage current, and operating temperature range. Substitute parts are grouped into three categories based on their relationship to the original specification:

Parametric Equivalents maintain identical electrical specifications (85 V, 140 mA) with the same package and differ only in packaging format (Cut Tape vs. Tape & Reel) or product status (Active vs. Discontinued). These parts are direct functional replacements.

Direct Manufacturer Alternatives are sourced from different manufacturers (Nexperia USA Inc.) and feature modified electrical ratings (75 V, 160 mA) while maintaining the same package format and diode configuration. These parts operate within compatible electrical ranges for applications not requiring the full 85 V specification.

Manufacturer Recommended Alternatives from Micro Commercial Co, Panjit International Inc., and Infineon Technologies provide enhanced current ratings (200–215 mA) or modified voltage ratings (70–80 V) in the same SOT-23-3 package. These parts accommodate applications requiring higher current capacity or operate within reduced voltage margins.

All substitute parts maintain the SOT-23-3 package format, small-signal diode speed classification, 3 µs reverse recovery time, 5 nA reverse leakage current, and RoHS3 compliance. Differences in voltage rating and current capacity determine suitability for specific circuit requirements.

Engineering Selection Recommendations

Primary Substitutes (Parametric Equivalents): BAV199-7-F and BAV199Q-13-F from Diodes Incorporated are direct parametric equivalents to the original BAV199, maintaining identical electrical specifications (85 V, 140 mA) and operating temperature range. Both parts are Active status and ROHS3 compliant. BAV199-7-F is supplied in Cut Tape & Digi-Reel packaging, while BAV199Q-13-F is supplied in Tape & Reel format and carries AEC-Q101 automotive qualification. Selection between these two depends on packaging requirements and whether automotive-grade qualification is necessary for the application.

Secondary Substitutes (Nexperia Alternatives): BAV199,215 and BAV199,235 from Nexperia USA Inc. feature reduced reverse voltage rating (75 V) and increased current capacity (160 mA). Both parts are Active status and ROHS3 compliant with AEC-Q101 automotive qualification. These parts are suitable for applications where the 85 V specification is not required and where the higher current rating provides design margin.

Enhanced Current Capacity Alternatives: BAV199-TP (Micro Commercial Co), BAV199_R1_00001 (Panjit International Inc.), BAV199E6327HTSA1, and BAV199E6433HTMA1 (Infineon Technologies) provide current ratings of 200–215 mA, exceeding the original 140 mA specification. The Infineon parts feature faster reverse recovery time (1.5 µs vs. 3 µs) and are designated Last Time Buy status. These alternatives are suitable for designs requiring higher current capacity within compatible voltage ranges.

All substitute parts maintain SOT-23-3 package compatibility, small-signal diode classification, and RoHS3 compliance. Selection criteria should prioritize Active status parts (BAV199-7-F, BAV199Q-13-F, Nexperia, and Panjit alternatives) over Last Time Buy designations (Infineon parts) for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can BAV199-7-F directly replace the discontinued BAV199?

A: Yes. BAV199-7-F is a parametric equivalent manufactured by Diodes Incorporated with identical electrical specifications (85 V, 140 mA), operating temperature range (-65°C to 150°C), and SOT-23-3 package. The primary difference is product status (Active vs. Discontinued) and RoHS3 compliance. Packaging format differs (Cut Tape & Digi-Reel vs. standard packaging), but electrical function is identical.

Q: What is the difference between BAV199-7-F and BAV199Q-13-F?

A: Both parts are parametric equivalents with identical electrical specifications. BAV199-7-F is supplied in Cut Tape & Digi-Reel packaging, while BAV199Q-13-F is supplied in Tape & Reel format. BAV199Q-13-F carries AEC-Q101 automotive qualification and Grade designation, making it suitable for automotive applications. Selection depends on packaging requirements and whether automotive qualification is necessary.

Q: Can I use Nexperia BAV199,215 or BAV199,235 as substitutes?

A: These parts are compatible substitutes with the same SOT-23-3 package and diode configuration. However, they feature reduced reverse voltage rating (75 V vs. 85 V) and increased current capacity (160 mA vs. 140 mA). Use these parts only if your circuit operates below 75 V and does not require the full 85 V specification. Both parts are Active status and ROHS3 compliant.

Q: What are the advantages of Infineon BAV199E6327HTSA1 and BAV199E6433HTMA1?

A: These Infineon parts provide 200 mA current capacity (vs. 140 mA original) and faster reverse recovery time (1.5 µs vs. 3 µs). They operate at 80 V reverse voltage rating. However, both parts are designated Last Time Buy status, indicating limited future availability. Use these parts only if higher current capacity and faster switching are required and supply continuity is not a concern.

Q: Are all substitute parts in the same SOT-23-3 package?

A: Yes. All substitute parts listed maintain the SOT-23-3 (TO-236-3, SC-59) surface mount package format. Physical footprint and pin configuration are identical, allowing direct PCB layout compatibility. Packaging format (Cut Tape, Tape & Reel, Digi-Reel) refers to supply method, not physical package dimensions.

Q: Which substitute part offers the best long-term availability?

A: BAV199-7-F and BAV199Q-13-F from Diodes Incorporated, along with Nexperia BAV199,215 and BAV199,235, and Panjit BAV199_R1_00001 are all designated Active status, indicating ongoing production and supply. Infineon parts (BAV199E6327HTSA1 and BAV199E6433HTMA1) are Last Time Buy status, indicating limited future availability. For long-term design assurance, prioritize Active status alternatives.

Q: Do all substitute parts meet RoHS3 compliance?

A: All substitute parts listed are ROHS3 compliant. The original BAV199 is RoHS non-compliant. If RoHS3 compliance is required for your application, any of the listed substitute parts satisfy this requirement.

Q: Can I use BAV199-TP for higher current applications?

A: Yes. BAV199-TP from Micro Commercial Co provides 215 mA current capacity, the highest among all listed alternatives. However, it features reduced reverse voltage rating (70 V vs. 85 V). Use this part only if your circuit operates below 70 V and requires the higher current capacity. The part is Active status and ROHS3 compliant.
