Substitute Part Grouping Explanation

Substitution of the B350BE-13 is determined by equivalence in the following critical parameters:

Voltage Rating: Reverse voltage must equal 50 V DC maximum
Current Rating: Average rectified current must equal 3 A
Package Type: Surface Mount SMB (DO-214AA) form factor
Technology: Schottky rectifier diode
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Temperature Range: Operating junction temperature -55°C ~ 150°C

The B350B-13-F meets all these criteria and is manufactured by the same supplier (Diodes Incorporated) under the same base product number (B350). This part is classified as Active product status with improved inventory availability.

Engineering Selection Recommendations

The B350B-13-F is a direct functional substitute for the B350BE-13 based on matching voltage, current, package, and temperature specifications. The B350B-13-F is classified as Active product status, ensuring continued availability and supply chain reliability compared to the Obsolete B350BE-13.

Both parts maintain ROHS3 compliance and are assigned identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The B350B-13-F is supplied in Tape & Reel (TR) packaging format with Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating superior handling and storage characteristics.

Electrical parameter variations between the two parts are within acceptable tolerance ranges for Schottky rectifier diode applications: forward voltage differential of 50 mV at rated current, reverse leakage increase of 400 µA, and capacitance increase of 90 pF are characteristic of manufacturing process variations within the same product family.

Frequently Asked Questions (FAQ)

Q: Can B350B-13-F replace B350BE-13 in existing designs?

A: Yes. Both parts share identical voltage rating (50 V), current rating (3 A), package type (DO-214AA, SMB), mounting type (Surface Mount), and operating temperature range (-55°C ~ 150°C). The B350B-13-F is the Active product alternative to the Obsolete B350BE-13.

Q: What are the differences in electrical characteristics?

A: The B350B-13-F exhibits higher forward voltage (700 mV vs. 650 mV @ 3 A), higher reverse leakage current (500 µA vs. 100 µA @ 50 V), and higher capacitance (200 pF vs. 110 pF @ 4V, 1MHz). These variations are within normal manufacturing tolerances for Schottky diodes in the same product family.

Q: Are there packaging differences?

A: The B350BE-13 packaging format is not specified in available data. The B350B-13-F is supplied in Tape & Reel (TR) format with MSL 1 (Unlimited). Both use identical DO-214AA, SMB package / case configuration for Surface Mount assembly.

Q: Do both parts meet compliance requirements?

A: Yes. Both B350BE-13 and B350B-13-F are ROHS3 Compliant. The B350B-13-F is REACH Unaffected, while the B350BE-13 is REACH Affected. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Why is B350B-13-F recommended over B350BE-13?

A: The B350B-13-F is classified as Active product status with significantly higher inventory availability (10,400 Pcs vs. 869 Pcs). The Obsolete status of B350BE-13 indicates discontinued production and limited future supply.

Q: Are there any application restrictions for the substitute part?

A: No application restrictions exist based on provided specifications. Both parts are Schottky rectifier diodes with identical voltage, current, and temperature ratings suitable for the same circuit applications.
