Substitute Part Grouping Explanation

Substitute parts for the ES3DBHR5G are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents share identical or superior electrical specifications across all critical parameters: 200 V reverse voltage rating, 3 A average rectified current, DO-214AA (SMB) package, surface mount technology, and operating temperature range of -55°C to 150°C. These parts are direct functional replacements with no design modifications required.

Similar Parts maintain the same 200 V reverse voltage and DO-214AA (SMB) package but differ in average rectified current capacity (1 A or 2 A) or forward voltage characteristics. These parts are suitable for applications where the full 3 A current rating is not required, or where lower forward voltage drop is beneficial.

The critical parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) Maximum: 200 V
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Current - Average Rectified (Io): 3 A (for parametric equivalents) or lower (for similar parts)

Engineering Selection Recommendations

Parametric Equivalent Selection (Direct Replacement)

The HS3DB and HS3DB R5G parts from Taiwan Semiconductor Corporation are parametric equivalents to the ES3DBHR5G, maintaining 200 V reverse voltage, 3 A average rectified current, and DO-214AA (SMB) package specifications. Both parts are ROHS3 compliant and REACH unaffected. The HS3DB is available in Tape & Reel (TR) packaging with Active product status and 5900 pieces in inventory. The HS3DB R5G is available in Cut Tape (CT) packaging but carries Discontinued at DiGi Electronics status with 3893 pieces in inventory.

The ES3DB R5G from Taiwan Semiconductor Corporation is also a parametric equivalent with identical electrical ratings and Cut Tape (CT) packaging. This part is Discontinued at DiGi Electronics but maintains 1089 pieces in inventory and ROHS3 compliance.

Active Product Preference

For new designs and ongoing production, the HS3DB is the recommended parametric equivalent due to its Active product status, higher inventory availability (5900 pieces), and identical electrical performance. This part eliminates obsolescence risk associated with discontinued variants.

Similar Part Selection (Current-Reduced Applications)

The ER3DB-TP from Micro Commercial Co provides 3 A current capacity with identical 200 V reverse voltage and DO-214AA (SMB) package. This part features lower forward voltage (0.95 V @ 3 A versus 1 V @ 3 A) and lower reverse leakage current (5 µA @ 200 V versus 100 µA @ 200 V), with Active product status and 2200 pieces in inventory.

For applications requiring 2 A or less, the ER2D-LTP (Micro Commercial Co), ES2D-13-F (Diodes Incorporated), ESH2D-E3/52T, and ESH2D-E3/5BT (Vishay) are suitable alternatives. These parts maintain 200 V reverse voltage and DO-214AA (SMB) package compatibility with Active product status and substantial inventory availability.

Compliance and Certification

All listed substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH unaffected status, matching the ES3DBHR5G certification profile.

Frequently Asked Questions (FAQ)

Q: Can the ES3DB R5G be used as a direct replacement for the ES3DBHR5G?

A: The ES3DB R5G is a parametric equivalent with identical electrical specifications (200 V, 3 A, 35 ns reverse recovery time) and DO-214AA (SMB) package. However, this part is Discontinued at DiGi Electronics. For new designs, the HS3DB is the recommended active equivalent.

Q: What is the difference between the HS3DB and HS3DB R5G?

A: Both parts are parametric equivalents with identical electrical specifications. The HS3DB is available in Tape & Reel (TR) packaging with Active product status. The HS3DB R5G is available in Cut Tape (CT) packaging but is Discontinued at DiGi Electronics. Selection depends on packaging format requirements and supply chain considerations.

Q: Can I use a 2 A rated diode (ER2D-LTP, ES2D-13-F, ESH2D-E3/5BT) in place of the 3 A ES3DBHR5G?

A: A 2 A rated diode can be used only if the application circuit does not require the full 3 A current capacity. The 2 A parts maintain the same 200 V reverse voltage and DO-214AA (SMB) package, but are rated for lower average rectified current. Circuit analysis is required to confirm current requirements do not exceed 2 A.

Q: What is the significance of the reverse recovery time (trr) difference between parts?

A: The ES3DBHR5G has a 35 ns reverse recovery time. The HS3DB and HS3DB R5G have 50 ns reverse recovery time. Lower reverse recovery time reduces switching losses in high-frequency applications. The 15 ns difference is not significant for standard rectification applications but may affect performance in switching power supplies operating above 100 kHz.

Q: Are there package differences between substitute parts?

A: Most substitute parts use the DO-214AA (SMB) package matching the ES3DBHR5G. The ES2DA-13-F uses a DO-214AC (SMA) package, which is physically different and not interchangeable without PCB redesign. Verify package compatibility before selection.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) packaging is supplied in individual tape segments suitable for manual assembly or small-volume production. Tape & Reel (TR) packaging is supplied on continuous reels suitable for automated pick-and-place assembly. Selection depends on assembly process requirements. Both formats contain identical components.

Q: Why does the ES3DBHR5G have higher reverse leakage current (100 µA) compared to ER3DB-TP (5 µA)?

A: Reverse leakage current varies by manufacturer and process technology. The ER3DB-TP exhibits lower leakage, which may reduce power dissipation in standby conditions. Both values are within acceptable ranges for general-purpose rectification. Application-specific leakage requirements determine whether this difference is significant.

Q: Can I substitute the ES3DBHR5G with a part from a different manufacturer?

A: Yes. The ER3DB-TP (Micro Commercial Co), ES2D-13-F (Diodes Incorporated), and ESH2D-E3/5BT (Vishay) are functionally compatible alternatives with identical or superior electrical specifications and DO-214AA (SMB) package compatibility. All parts maintain ROHS3 compliance and equivalent operating temperature ranges.

Q: What does "Discontinued at DiGi Electronics" mean for the ES3DB R5G and HS3DB R5G?

A: "Discontinued at DiGi Electronics" indicates that these parts are no longer actively stocked or promoted by DiGi Electronics as a distributor, though inventory may remain available. For long-term supply assurance, Active status parts such as HS3DB, ER3DB-TP, or ES2D-13-F are preferred for new designs.
