Substitute Part Grouping Explanation

Substitution of the S2AHE3_A/I is determined by equivalence across all critical electrical parameters and mechanical specifications. The substitute part S2A-E3/52T maintains identical performance characteristics:

Key Parameters for Substitution:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 1.5 A
• Reverse Recovery Time (trr): 2 µs
• Current - Reverse Leakage @ Vr: 1 µA @ 50 V
• Capacitance @ Vr, F: 16 pF @ 4V, 1MHz
• Package / Case: DO-214AA, SMB
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute differs only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and supplier device configuration, with no impact on electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the S2AHE3_A/I and S2A-E3/52T are Active product status components manufactured by Vishay General Semiconductor - Diodes Division. Both devices carry ROHS3 compliance and REACH Unaffected status, meeting environmental regulatory requirements. Both are qualified to AEC-Q101 automotive standard, ensuring suitability for automotive applications.

Selection between these parts is determined by packaging and supply requirements:

• S2AHE3_A/I: Tape & Reel (TR) packaging format. Use when bulk reel quantities are required for automated assembly processes.
• S2A-E3/52T: Cut Tape (CT) & Digi-Reel® packaging format. Use when smaller quantities, mixed component orders, or alternative reel configurations are required.

Both parts deliver identical electrical performance and mechanical compatibility in the DO-214AA (SMB) surface mount package.

Frequently Asked Questions (FAQ)

Q: Can S2A-E3/52T be used as a direct replacement for S2AHE3_A/I in circuit design?

A: Yes. Both parts are electrically and mechanically identical. All critical parameters including voltage rating (50 V), current rating (1.5 A), forward voltage (1.15 V @ 1.5 A), reverse recovery time (2 µs), and package type (DO-214AA, SMB) are identical. The only difference is packaging format.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) provides components on continuous reels suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides components in smaller quantities or alternative reel configurations, offering flexibility for mixed component orders or lower-volume production runs. Both formats contain the same component in the same DO-214AA (SMB) package.

Q: Are both parts suitable for automotive applications?

A: Yes. Both S2AHE3_A/I and S2A-E3/52T carry AEC-Q101 automotive qualification and are classified as automotive-grade components. Both are ROHS3 compliant and REACH Unaffected.

Q: What is the operating temperature range for these diodes?

A: Both parts operate across a junction temperature range of -55°C to 150°C, suitable for industrial and automotive environments.

Q: Do these parts require special handling or storage considerations?

A: Both parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component handling and storage practices apply.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical and mechanical specifications are identical. Designs using S2AHE3_A/I can be sourced with S2A-E3/52T without circuit modification or re-qualification, provided the packaging format change does not affect assembly process requirements.
