ER2A-LTP Equivalent & Substitute Parts

Part Overview

The ER2A-LTP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 50 V DC reverse voltage and 2 A average rectified current in a DO-214AA (SMB) surface mount package. This device features fast recovery characteristics with a reverse recovery time of 35 ns and is classified as a standard technology rectifier.

The ER2A-LTP carries a "Not For New Designs" product status, indicating that this component is no longer recommended for new circuit development. Identifying equivalent and substitute parts is necessary to support existing designs, facilitate production continuity, and enable migration to active product alternatives that meet the same electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution of the ER2A-LTP is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 50 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: Must not exceed application requirements
Reverse Recovery Time (trr): Fast recovery classification preferred for switching applications
Current - Reverse Leakage @ Vr: Must remain within acceptable limits for the application
Operating Temperature - Junction: Must encompass application operating range

Substitute parts are grouped into two categories:

Category A - Full Electrical Equivalents (50 V, 2 A): Parts that meet or exceed all primary substitution criteria with identical voltage and current ratings.

Category B - Partial Equivalents (50 V, 1 A): Parts that meet voltage requirements but with reduced current rating, suitable only for applications with lower current demands.

Engineering Selection Recommendations

Full Electrical Equivalents (50 V, 2 A Rating):

ES2A-13-F (Diodes Incorporated) is the preferred substitute for the ER2A-LTP. This part maintains identical voltage and current ratings, features superior fast recovery characteristics (25 ns trr versus 35 ns), and carries active product status. The forward voltage drop of 920 mV @ 2 A is lower than the ER2A-LTP specification, resulting in reduced power dissipation. All compliance certifications match the original part.

ES2A-E3/5BT (Vishay General Semiconductor - Diodes Division) provides full electrical equivalence with 50 V, 2 A ratings and fast recovery performance (30 ns trr). Forward voltage of 900 mV @ 2 A offers improved efficiency. This part is actively manufactured and fully compliant. The maximum junction temperature of 150°C is lower than the ER2A-LTP; applications requiring operation above 150°C require verification against circuit requirements.

CGRB201-G (Comchip Technology) meets the 50 V, 2 A voltage and current requirements with identical package specifications. However, this part employs standard recovery technology (> 500ns) rather than fast recovery, making it unsuitable for high-frequency switching applications. The forward voltage of 1.1 V @ 2 A is higher than the ER2A-LTP, resulting in increased power dissipation. This substitute is appropriate only for low-frequency rectification circuits where switching speed is not critical.

ES2A (YAGEO) is listed as an equivalent with 50 V rating and 0.95 V forward voltage specification. Detailed electrical parameters are not fully specified in available documentation. This part carries active status and full compliance certifications.

Partial Equivalent (50 V, 1 A Rating):

SURS8105T3G-VF01 (onsemi) is rated for 50 V, 1 A operation and is not a direct substitute for 2 A applications. This part is qualified to AEC-Q101 automotive standards and features fast recovery characteristics (35 ns trr). The lower current rating restricts its use to applications with maximum 1 A requirements. The operating temperature range of -65°C ~ 175°C matches the ER2A-LTP specification.

Compliance and Regulatory Status:

All substitute parts listed carry ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity classification, matching the ER2A-LTP regulatory profile. All parts are classified under HTSUS code 8541.10.0080 and ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can CGRB201-G be used as a direct replacement for ER2A-LTP in all applications?

A: CGRB201-G meets the voltage (50 V) and current (2 A) requirements and uses the same DO-214AA package. However, it employs standard recovery technology (> 500ns) instead of fast recovery (≤ 500ns). In high-frequency switching applications, the slower recovery time may cause increased switching losses and electromagnetic interference. For low-frequency rectification circuits, CGRB201-G is electrically compatible. The higher forward voltage (1.1 V versus 950 mV) results in greater power dissipation in both applications.

Q: What is the difference between ES2A-13-F and ES2A-E3/5BT?

A: Both parts are 50 V, 2 A fast recovery diodes in DO-214AA packages. ES2A-13-F offers a faster reverse recovery time (25 ns versus 30 ns) and lower forward voltage (920 mV versus 900 mV). ES2A-E3/5BT has a slightly higher reverse leakage current (10 µA versus 5 µA). Both are suitable substitutes; selection depends on whether the application prioritizes recovery speed or leakage current performance.

Q: Can SURS8105T3G-VF01 replace ER2A-LTP?

A: SURS8105T3G-VF01 is rated for 1 A average rectified current, while ER2A-LTP is rated for 2 A. This part cannot be used in applications requiring 2 A operation. It is suitable only for circuits with maximum 1 A current demands. The 50 V voltage rating and DO-214AA package are compatible. SURS8105T3G-VF01 carries AEC-Q101 automotive qualification, making it appropriate for automotive applications within its 1 A current limit.

Q: Why is ER2A-LTP marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends against using this part in new circuit designs. Existing designs using ER2A-LTP remain supported for production continuity. For new designs, ES2A-13-F or ES2A-E3/5BT are recommended as they carry active product status and offer equivalent or superior electrical performance.

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

A: All listed substitutes use the DO-214AA (SMB) surface mount package, ensuring mechanical and thermal compatibility with ER2A-LTP. Printed circuit board layouts and thermal management designs require no modification for package substitution.

Q: What compliance certifications apply to these substitute parts?

A: All substitute parts listed are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity classification. SURS8105T3G-VF01 additionally carries AEC-Q101 automotive qualification. These certifications match the ER2A-LTP regulatory profile, ensuring no compliance issues during substitution.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage drop directly impacts power dissipation and voltage regulation. ES2A-13-F and ES2A-E3/5BT feature lower forward voltages (920 mV and 900 mV respectively) compared to ER2A-LTP (950 mV), resulting in reduced heat generation. CGRB201-G has higher forward voltage (1.1 V), increasing power dissipation. In precision rectification circuits, forward voltage differences may require adjustment of downstream voltage regulation or filtering components.

Q: What is the significance of reverse recovery time in diode selection?

A: Reverse recovery time (trr) determines how quickly a diode transitions from conducting to blocking state. Fast recovery diodes (≤ 500ns) are essential in high-frequency switching applications to minimize switching losses and electromagnetic interference. Standard recovery diodes (> 500ns) are adequate for low-frequency rectification. ER2A-LTP specifies 35 ns fast recovery; ES2A-13-F offers 25 ns, and CGRB201-G does not specify fast recovery characteristics.
