Substitute Part Grouping Explanation
Substitution of the HS2BA M2G is determined by the following critical parameters:
Primary Substitution Criteria:
- Voltage - DC Reverse (Vr) (Max): 100 V minimum
- Current - Average Rectified (Io): 1.5 A minimum
- Package / Case: DO-214AC (SMA) surface mount
- Mounting Type: Surface Mount
- Technology: Standard rectifier diode
Secondary Compatibility Factors:
- Voltage - Forward (Vf): Forward voltage drop at rated current
- Reverse Recovery Time (trr): Recovery speed for switching applications
- Current - Reverse Leakage: Leakage characteristics at rated reverse voltage
- Operating Temperature Range: Junction temperature limits
- RoHS and MSL Compliance: Environmental and handling requirements
Parametric Equivalent Parts maintain all primary and secondary specifications identically to the HS2BA M2G. These parts are direct replacements with no circuit redesign required.
Similar Parts operate at reduced current ratings (1 A versus 1.5 A) while maintaining 100 V reverse voltage and DO-214AC packaging. These parts are suitable for applications where the full 1.5 A current capacity is not required. Forward voltage characteristics and reverse recovery times may differ within acceptable ranges for general-purpose rectification.

Engineering Selection Recommendations
Parametric Equivalent Selection (Direct Replacement):
The HS2BA (Tape & Reel packaging) is the primary equivalent for the HS2BA M2G. This part maintains identical electrical specifications and is currently in Active product status. The HS2BA R3G provides equivalent electrical performance but is discontinued at DiGi Electronics; selection of this part should be limited to applications where Cut Tape packaging is specifically required and alternative sources are available.
Similar Part Selection (Reduced Current Rating):
Applications requiring less than 1.5 A average rectified current may utilize 1 A rated alternatives. Selection among similar parts should follow these criteria:
-
Active Product Status Priority: ES1B-13-F (Diodes Incorporated), ES1B-E3/5AT (Vishay), ES1B-M3/5AT (Vishay), ES1B-M3/61T (Vishay), ES1BHE3_A/H (Vishay), and ES1BHE3_A/I (Vishay) are all in Active product status and suitable for new designs.
-
Automotive Grade Requirement: ES1BHE3_A/H and ES1BHE3_A/I carry AEC-Q101 automotive qualification and are appropriate for automotive applications.
-
Packaging Availability: Tape & Reel (TR) packaging is available from multiple manufacturers. Cut Tape (CT) & Digi-Reel® packaging is available from Vishay (ES1B-E3/5AT).
-
Avoid Not For New Designs: ES1B-LTP (Micro Commercial Co) carries "Not For New Designs" status and should not be selected for new product development.
Compliance Verification:
All listed parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity, and REACH Unaffected status, consistent with the HS2BA M2G requirements.
Frequently Asked Questions (FAQ)
Q: Can the HS2BA (1.5 A, Tape & Reel) directly replace the HS2BA M2G?
A: Yes. The HS2BA is a parametric equivalent with identical electrical specifications. The difference is packaging format: HS2BA is supplied in Tape & Reel (TR) format while HS2BA M2G was supplied in an unspecified format. Both are DO-214AC (SMA) surface mount packages suitable for the same PCB assembly processes.
Q: Why are 1 A rated diodes listed as alternatives to the 1.5 A HS2BA M2G?
A: The 1 A rated parts (CGRA4002-G, ES1B series) maintain the same 100 V reverse voltage rating and DO-214AC package. They are suitable substitutes for applications where the circuit current demand does not exceed 1 A. The 0.5 A reduction in current capacity does not affect voltage handling or package compatibility.
Q: What is the difference between ES1B-E3/5AT and ES1B-M3/5AT?
A: Both parts are manufactured by Vishay and share identical electrical specifications (100 V, 1 A, 920 mV forward voltage, 25 ns recovery time). The difference is in packaging format: ES1B-E3/5AT is supplied in Cut Tape (CT) & Digi-Reel® format, while ES1B-M3/5AT is supplied in Tape & Reel (TR) format. Electrical performance is equivalent.
Q: Should ES1BHE3_A/H or ES1BHE3_A/I be selected for automotive applications?
A: Both ES1BHE3_A/H and ES1BHE3_A/I carry AEC-Q101 automotive qualification and are appropriate for automotive-grade applications. Selection between these two variants should be based on specific packaging or supply chain requirements, as electrical specifications are identical.
Q: Why is ES1B-LTP not recommended despite being available?
A: ES1B-LTP carries a "Not For New Designs" product status designation. This indicates the manufacturer is phasing out this part number. For new product development, selection should be limited to parts with Active product status to ensure long-term supply availability and manufacturer support.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed equivalent and substitute parts maintain ROHS3 compliance, consistent with the HS2BA M2G. All parts also carry MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status.
Q: What is the significance of the 50 ns reverse recovery time in the HS2BA M2G compared to 25 ns in ES1B variants?
A: The HS2BA M2G specifies 50 ns reverse recovery time, while ES1B variants specify 25 ns. Both fall within the "Fast Recovery ≤ 500ns, > 200mA (Io)" classification. The faster 25 ns recovery in ES1B parts may provide improved switching performance in high-frequency applications, but both are suitable for general-purpose rectification.
Q: Can forward voltage differences between parts affect circuit performance?
A: Forward voltage differences are minor across all listed parts (920 mV to 1.1 V at rated current). In general-purpose rectification applications, these variations do not significantly impact circuit performance. In precision applications where forward voltage drop is critical to circuit function, forward voltage specifications should be verified against circuit design requirements.
Q: Is the DO-214AC package identical across all listed parts?
A: Yes. All listed parts use the DO-214AC (SMA) surface mount package. This ensures mechanical and electrical compatibility with existing PCB layouts and assembly processes. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) affects supply and handling but not PCB mounting or electrical function.
