Substitute Part Grouping Explanation

Substitution of the ES2A-13 is determined by the following critical parameters:

Electrical Requirements:

Voltage - DC Reverse (Vr) rating must be ≥ 50 V
Current - Average Rectified (Io) must be ≥ 2 A
Package and mounting type must be DO-214AA (SMB) Surface Mount

Performance Characteristics:

Forward voltage drop (Vf) at rated current
Reverse recovery time (trr) and speed classification
Reverse leakage current characteristics
Operating temperature range

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts with identical or superior electrical specifications and matching package type, enabling direct replacement without circuit redesign.

Functional Substitutes: Parts meeting minimum voltage and current requirements with the same package type but differing in secondary characteristics such as recovery speed or forward voltage, requiring design verification.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent):

ES2A-13-F (Diodes Incorporated) is the primary equivalent for ES2A-13. This part maintains identical electrical specifications including 50 V reverse voltage, 2 A current rating, 920 mV forward voltage at 2 A, and 25 ns reverse recovery time. The ES2A-13-F is available in active product status with ROHS3 compliance and Tape & Reel packaging, providing 10,400 units in stock. This part is suitable for direct substitution without circuit modification.

Functional Substitutes (Voltage and Current Compatible):

CGRB201-G (Comchip Technology) meets the minimum voltage and current requirements with 50 V reverse voltage and 2 A current rating in DO-214AA package. Forward voltage is specified at 1.1 V @ 2 A, representing a 180 mV increase over the ES2A-13. Recovery speed is classified as Standard Recovery (>500ns), differing from the fast recovery characteristic of the original part. This part is ROHS3 compliant and active in production with 20,272 units available.

S2A (Diotec Semiconductor) provides 50 V reverse voltage and 2 A current rating in DO-214AA package with forward voltage of 1.15 V @ 2 A and 1.5 µs reverse recovery time. Operating temperature range is -50°C to 150°C. This part is ROHS3 compliant and active with 7,004 units in stock.

Compliance Considerations:

The original ES2A-13 is RoHS non-compliant. All active substitute parts (ES2A-13-F, CGRB201-G, S2A) are ROHS3 compliant, meeting current regulatory requirements for new designs and procurement.

Frequently Asked Questions (FAQ)

Q: Can ES2A-13-F directly replace ES2A-13 in existing designs?

A: Yes. ES2A-13-F is a parametric equivalent with identical voltage rating (50 V), current rating (2 A), forward voltage (920 mV @ 2 A), and reverse recovery time (25 ns). Both parts use DO-214AA (SMB) Surface Mount packaging. Direct substitution is supported without circuit redesign.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Recovery speed refers to the reverse recovery time (trr), which is the time required for a diode to stop conducting when reverse bias is applied. ES2A-13 and ES2A-13-F are fast recovery diodes with trr of 25 ns. CGRB201-G and S2A are standard recovery diodes with longer recovery times (>500ns and 1.5 µs respectively). Fast recovery diodes are preferred in high-frequency switching applications to minimize switching losses and electromagnetic interference.

Q: Can CGRB201-G or S2A be used as substitutes for ES2A-13?

A: CGRB201-G and S2A meet the minimum voltage (50 V) and current (2 A) requirements and use the same DO-214AA package. However, both parts have higher forward voltage drops (1.1 V and 1.15 V respectively versus 920 mV) and standard recovery speed characteristics instead of fast recovery. These differences may affect circuit performance in high-frequency or efficiency-critical applications. Design verification is required before substitution.

Q: Why is the ES2A-13 discontinued?

A: The ES2A-13 is discontinued at DiGi Electronics. The active equivalent ES2A-13-F provides the same electrical performance with improved regulatory compliance (ROHS3).

Q: What does ROHS3 compliance mean?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the part meets European Union regulations restricting the use of specific hazardous materials including lead, cadmium, mercury, and certain brominated flame retardants. The original ES2A-13 is RoHS non-compliant; all active substitutes are ROHS3 compliant.

Q: Are all substitute parts available in Tape & Reel packaging?

A: ES2A-13-F and CGRB201-G are specified with Tape & Reel (TR) packaging. S2A packaging is not specified in the provided data. Confirm packaging availability with the supplier for production requirements.

Q: What is the operating temperature range difference between substitutes?

A: ES2A-13 and ES2A-13-F operate from -55°C to 150°C. CGRB201-G specifies 150°C maximum (lower bound not specified). S2A operates from -50°C to 150°C. For applications requiring operation below -50°C, ES2A-13-F is the appropriate choice.
