Substitute Part Grouping Explanation

Substitution of the B120BE-13 is based on electrical and mechanical parameter equivalence within the Schottky rectifier diode category. The following parameters determine substitution eligibility:

Primary Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 20 V
• Current - Average Rectified (Io): 1 A
• Technology: Schottky
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 1 A

Secondary Compatibility Parameters:

• Speed classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction range compatibility

The B120B-13-F meets all primary equivalence criteria and maintains functional compatibility with the B120BE-13 across core electrical specifications and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The B120B-13-F is the direct substitute for the B120BE-13. Both components share identical electrical specifications across voltage, current, and forward voltage parameters. The B120B-13-F is currently in active production status, ensuring long-term availability and supply chain continuity.

Key selection factors:

Product Status: The B120B-13-F is classified as Active, whereas the B120BE-13 is Obsolete. Selection of the active part ensures access to current manufacturing processes and inventory.

Compliance: Both parts maintain ROHS3 compliance and share identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and procurement purposes.

Operating Temperature Range: The B120B-13-F extends the lower operating temperature limit to -65°C compared to the B120BE-13 at -55°C, providing enhanced performance in low-temperature applications.

Packaging: The B120B-13-F is supplied in Tape & Reel (TR) format, standard for automated assembly processes. The B120BE-13 packaging format is not specified in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the B120B-13-F directly replace the B120BE-13 in existing designs?

A: Yes. The B120B-13-F meets all primary electrical specifications of the B120BE-13, including 20 V reverse voltage rating, 1 A average rectified current, 500 mV forward voltage at 1 A, and fast recovery speed classification. Both components use the DO-214AA SMB package for surface mount applications.

Q: What is the difference in operating temperature range between these parts?

A: The B120B-13-F operates from -65°C to 150°C, while the B120BE-13 operates from -55°C to 150°C. The B120B-13-F provides an additional 10°C of low-temperature capability.

Q: Are there differences in reverse leakage current between these parts?

A: Yes. The B120BE-13 specifies 100 µA reverse leakage at 20 V, while the B120B-13-F specifies 500 µA at the same conditions. This difference does not affect substitution eligibility for standard rectifier applications.

Q: Are there differences in junction capacitance?

A: Yes. The B120BE-13 specifies 50 pF at 4 V and 1 MHz, while the B120B-13-F specifies 110 pF at the same conditions. This difference does not affect substitution eligibility for standard rectifier applications.

Q: What packaging format is the B120B-13-F supplied in?

A: The B120B-13-F is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the B120BE-13 and B120B-13-F are ROHS3 compliant and REACH unaffected or affected status as specified in their respective datasheets.

Q: Why is the B120BE-13 listed as obsolete?

A: The B120BE-13 has been discontinued from active production. The B120B-13-F is the active equivalent part and should be used for all new designs and procurement.
