Substitute Part Grouping Explanation
Substitute parts for the ES2BB-HF are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:
Primary Matching Parameters:
- Voltage - DC Reverse (Vr) (Max): 100 V
- Current - Average Rectified (Io): 2 A
- Voltage - Forward (Vf) (Max) @ If: 1 V @ 2 A
- Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
- Package / Case: DO-214AA, SMB (surface mount)
- Mounting Type: Surface Mount
- Operating Temperature - Junction: -55°C to 150°C
- RoHS Status: ROHS3 Compliant
The UF2B_R1_00001 manufactured by Panjit International Inc. meets all primary matching parameters. Both parts share identical voltage ratings, current ratings, forward voltage specifications, fast recovery speed classification, package type, mounting configuration, temperature range, and RoHS compliance status. Variations in reverse recovery time (35 ns vs. 50 ns), reverse leakage current (5 µA vs. 1 µA), and junction capacitance (40 pF vs. 28 pF) remain within acceptable tolerance ranges for general-purpose rectifier applications and do not preclude substitution.

Engineering Selection Recommendations
Both the ES2BB-HF and UF2B_R1_00001 are Active product status components with full RoHS3 compliance and MSL 1 rating. Selection between these parts is based on availability and supply chain requirements.
The ES2BB-HF (Comchip Technology) features a reverse recovery time of 35 ns and reverse leakage current of 5 µA at 100 V. Current inventory: 939 pieces.
The UF2B_R1_00001 (Panjit International Inc.) features a reverse recovery time of 50 ns and reverse leakage current of 1 µA at 100 V. Current inventory: 1586 pieces.
Both parts satisfy the electrical specifications for 100 V, 2 A general-purpose rectification applications with fast recovery characteristics. The UF2B_R1_00001 offers superior reverse leakage performance and lower junction capacitance, while the ES2BB-HF provides faster reverse recovery. Component selection should be determined by circuit performance requirements and procurement availability.
Frequently Asked Questions (FAQ)
Q: Can the UF2B_R1_00001 directly replace the ES2BB-HF in existing designs?
A: Yes. Both parts share identical voltage ratings (100 V), current ratings (2 A), forward voltage specifications (1 V @ 2 A), speed classification (fast recovery ≤ 500ns), package type (DO-214AA, SMB), and operating temperature range (-55°C to 150°C). Both are RoHS3 compliant with MSL 1 rating.
Q: What are the differences between these two parts?
A: The primary differences are reverse recovery time (ES2BB-HF: 35 ns vs. UF2B_R1_00001: 50 ns), reverse leakage current (ES2BB-HF: 5 µA vs. UF2B_R1_00001: 1 µA @ 100 V), and junction capacitance (ES2BB-HF: 40 pF vs. UF2B_R1_00001: 28 pF @ 4V, 1MHz). These variations do not affect compatibility for general-purpose rectifier applications.
Q: Are the packages identical?
A: Yes. Both parts use the DO-214AA surface mount package, commonly referred to as SMB. Pin configuration and footprint are identical, allowing direct PCB substitution without layout modifications.
Q: Do both parts meet RoHS compliance requirements?
A: Yes. Both the ES2BB-HF and UF2B_R1_00001 are RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).
Q: Which part should be selected for high-speed switching applications?
A: The ES2BB-HF offers faster reverse recovery time (35 ns vs. 50 ns), making it suitable for applications requiring rapid diode turn-off. However, both parts meet the fast recovery classification (≤ 500ns) and are suitable for standard switching applications.
Q: Are there any temperature range limitations?
A: No. Both parts operate across the identical junction temperature range of -55°C to 150°C, supporting applications across industrial, commercial, and consumer temperature specifications.
