Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ES2DB-HF are qualified based on the following critical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 2 A or greater
• Package / Case: DO-214AA or SMB equivalent
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C or wider
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max) @ If: 1 V or less at rated current
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Technology: Standard

Parts meeting all primary criteria and maintaining secondary parameter compatibility are classified as direct parametric equivalents. Deviations in secondary parameters are noted where they occur.

Parameter Comparison

Engineering Selection Recommendations

Full Parametric Equivalents (Direct Substitutes):

ES2DB (MDD) and UF2D_R1_00001 (Panjit International Inc.) are direct parametric equivalents to the ES2DB-HF. Both parts maintain identical voltage and current ratings, equivalent forward voltage characteristics, and identical operating temperature ranges. Both are RoHS3 compliant and Active product status. The ES2DB features matching reverse recovery time (35 ns), while UF2D_R1_00001 exhibits improved reverse leakage characteristics (1 µA versus 5 µA) and lower junction capacitance (28 pF versus 40 pF).

Parametric Equivalent with Current Derating:

HS2D (SURGE) is a parametric equivalent with current derating. This part maintains the 200 V reverse voltage rating and identical forward voltage specification at its rated current (1.5 A). The reverse recovery time is 50 ns, compared to 35 ns for the primary part. HS2D is RoHS3 compliant and Active product status. Selection of HS2D requires circuit validation to confirm that 1.5 A average rectified current is sufficient for the application.

Compliance and Availability:

All substitute parts maintain RoHS3 compliance and Active product status. ES2DB (MDD) offers the highest inventory availability at 273,689 pieces. UF2D_R1_00001 (Panjit) provides 1,962 pieces with improved reverse leakage performance. HS2D (SURGE) provides 15,200 pieces with current derating consideration.

Frequently Asked Questions (FAQ)

Q: Can ES2DB (MDD) be used as a direct replacement for ES2DB-HF (Comchip)?

A: Yes. ES2DB maintains identical electrical specifications across all critical parameters: 200 V reverse voltage, 2 A average rectified current, 1 V forward voltage at 2 A, 35 ns reverse recovery time, and -55°C to 150°C operating temperature range. Both are RoHS3 compliant and packaged in DO-214AA/SMB. No circuit modification is required.

Q: What is the difference between UF2D_R1_00001 and ES2DB-HF?

A: UF2D_R1_00001 (Panjit) matches the ES2DB-HF in voltage, current, and forward voltage ratings. The primary differences are: reverse recovery time is 50 ns (versus 35 ns), reverse leakage current is 1 µA (versus 5 µA), and junction capacitance is 28 pF (versus 40 pF). These differences represent improved leakage and capacitance performance. Both are RoHS3 compliant and packaged identically.

Q: Can HS2D be used in place of ES2DB-HF?

A: HS2D is a parametric equivalent with current derating. It maintains the 200 V reverse voltage rating and identical forward voltage at its rated current of 1.5 A. The average rectified current is 1.5 A, compared to 2 A for ES2DB-HF. Selection requires verification that the application circuit operates within 1.5 A average rectified current limits. Package, mounting type, operating temperature range, and RoHS3 compliance are identical.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are packaged in DO-214AA/SMB surface mount format. ES2DB-HF and UF2D_R1_00001 are supplied in Tape & Reel (TR) packaging. ES2DB (MDD) is supplied in Tape & Reel (TR) packaging. HS2D (SURGE) is supplied in Bag packaging. Confirm packaging requirements with procurement specifications before selection.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) is provided for reference. ES2DB-HF and ES2DB both specify 35 ns. HS2D and UF2D_R1_00001 specify 50 ns. All parts are classified as Fast Recovery (≤ 500 ns, > 200 mA). The difference does not affect substitution eligibility for standard rectification applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ES2DB-HF, ES2DB, HS2D, and UF2D_R1_00001 are all RoHS3 compliant. This compliance status is maintained across all substitute selections.

Q: What does "Active" product status mean?

A: Active product status indicates the part is currently manufactured and available for procurement. All parts listed—ES2DB-HF, ES2DB, HS2D, and UF2D_R1_00001—maintain Active status, confirming ongoing availability and supply chain support.
