Substitute Part Grouping Explanation

Substitution of the CSA2M-E3/I is determined by electrical and mechanical compatibility within the following parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 1000 V
• Current - Average Rectified (Io): Must equal or exceed 1.6 A
• Voltage - Forward (Vf) (Max) @ If: Must not exceed the specified maximum at rated current
• Reverse Recovery Time (trr): Standard recovery classification maintained
• Current - Reverse Leakage @ Vr: Must not exceed specified maximum

Mechanical Compatibility Criteria:

• Package / Case: DO-214AC (SMA) surface mount package required
• Mounting Type: Surface mount configuration
• Operating Temperature Range: Must encompass -55°C to 150°C junction temperature

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Technology: Standard rectifier diode technology

The SA2M-E3/5AT meets all substitution criteria and is classified as a direct substitute for the CSA2M-E3/I.

Parameter Comparison

Engineering Selection Recommendations

The SA2M-E3/5AT is a direct substitute for the CSA2M-E3/I based on the following engineering factors:

Electrical Performance: The substitute part meets or exceeds all electrical requirements. The current rating of 2 A exceeds the 1.6 A requirement of the main part, providing design margin. Forward voltage is reduced from 1.15 V to 1.1 V at 2 A, and reverse recovery time is improved from 2.1 µs to 1.5 µs, indicating superior switching characteristics. Reverse leakage current is reduced from 5 µA to 3 µA, demonstrating improved reverse blocking performance.

Package and Mounting Compatibility: Both parts utilize the identical DO-214AC (SMA) surface mount package, ensuring direct mechanical and electrical compatibility on printed circuit boards without layout modifications.

Compliance and Production Status: The substitute part maintains ROHS3 compliance and is classified as active product status, ensuring continued availability and supply chain support. The main part is obsolete, making the substitute the appropriate selection for new designs and ongoing production.

Thermal Performance: Operating temperature range is identical across both parts, supporting equivalent thermal design requirements.

Frequently Asked Questions (FAQ)

Q: Can the SA2M-E3/5AT be used as a direct replacement for the CSA2M-E3/I in existing designs?

A: Yes. The SA2M-E3/5AT is a direct substitute. Both parts share identical package geometry (DO-214AC, SMA), mounting type (surface mount), and operating temperature range (-55°C to 150°C). Electrical parameters of the substitute meet or exceed the main part specifications. No circuit modifications or PCB layout changes are required.

Q: What are the key electrical differences between these parts?

A: The SA2M-E3/5AT provides higher current capacity (2 A versus 1.6 A), lower forward voltage drop (1.1 V versus 1.15 V at 2 A), faster reverse recovery time (1.5 µs versus 2.1 µs), and lower reverse leakage current (3 µA versus 5 µA at 1000 V). These represent performance improvements over the main part.

Q: Are there any packaging differences between the CSA2M-E3/I and SA2M-E3/5AT?

A: No packaging differences exist. Both parts are supplied in DO-214AC (SMA) surface mount packages. The main part is available in Cut Tape (CT) & Digi-Reel® packaging, while the substitute is supplied in Tape & Reel (TR) format. Both packaging formats are standard for surface mount component distribution and are compatible with automated assembly equipment.

Q: Why is the main part classified as obsolete?

A: The CSA2M-E3/I is no longer in active production by the manufacturer. The SA2M-E3/5AT represents the current active product offering from Vishay General Semiconductor - Diodes Division for this application category and should be selected for new designs and ongoing production requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CSA2M-E3/I and SA2M-E3/5AT are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both parts, indicating no special moisture handling requirements during storage or assembly.

Q: What is the voltage rating compatibility between these parts?

A: Both parts are rated for 1000 V DC reverse voltage, providing identical voltage withstand capability. Applications designed for 1000 V operation are fully supported by either part.
