ES2DAL Equivalent & Substitute Parts

Part Overview

The ES2DAL is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 2 A average rectified current in a surface mount Thin SMA package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of the ES2DAL is permissible with parts that maintain identical electrical ratings and mechanical compatibility. The critical parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A
Package / Case: DO-221AC, SMA Flat Leads
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C

The ERT2DAFC_R1_00001 manufactured by Panjit International Inc. satisfies all substitution criteria. Both parts share identical voltage and current ratings, forward voltage characteristics, package configuration, and thermal operating range. Differences in reverse recovery time (35 ns versus 25 ns) and junction capacitance (18 pF versus 30 pF) remain within acceptable tolerance for general-purpose rectification applications and do not preclude substitution.

Engineering Selection Recommendations

Both the ES2DAL and ERT2DAFC_R1_00001 are Active product status components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements rather than electrical performance differentiation. The ES2DAL is currently stocked at 7024 pieces, while the ERT2DAFC_R1_00001 maintains 1866 pieces in inventory. Both components are suitable for direct substitution in 200 V, 2 A general-purpose rectification circuits with surface mount assembly requirements. The identical forward voltage drop, reverse voltage rating, and thermal operating range ensure functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the ERT2DAFC_R1_00001 be used as a direct replacement for the ES2DAL in existing designs?

A: Yes. Both parts share identical voltage ratings (200 V), current ratings (2 A), forward voltage characteristics (950 mV @ 2 A), package configuration (DO-221AC, SMA Flat Leads), and thermal operating range (-55°C to 150°C). Direct substitution is permissible without circuit modification.

Q: What is the significance of the difference in reverse recovery time between these parts?

A: The ES2DAL specifies 35 ns reverse recovery time while the ERT2DAFC_R1_00001 specifies 25 ns. Both fall within the Fast Recovery classification (≤ 500 ns, > 200 mA). The faster recovery time of the ERT2DAFC_R1_00001 represents improved performance characteristics and does not create compatibility issues in substitution.

Q: Are there package compatibility concerns when substituting between these parts?

A: No. Both parts use the DO-221AC package with SMA Flat Leads configuration. PCB footprints, solder pad layouts, and mounting procedures are identical. The supplier device package designations (Thin SMA versus SMAF-C) refer to internal packaging for tape and reel delivery and do not affect board-level compatibility.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the ES2DAL and ERT2DAFC_R1_00001 are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080. Moisture sensitivity level is 1 (Unlimited) for both components, indicating no special handling requirements during storage or assembly.

Q: What is the difference in junction capacitance between these parts?

A: The ES2DAL specifies 18 pF at 4 V, 1 MHz, while the ERT2DAFC_R1_00001 specifies 30 pF at the same conditions. This difference does not affect general-purpose rectification applications and remains within acceptable tolerance for standard circuit designs.
