Key Parameters

Substitute Part Grouping Explanation

Substitution of the UG2C-E3/73 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage - DC Reverse (Vr) (Max): 150 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Voltage - Forward (Vf) (Max) @ If: 950 mV or lower @ 2 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA or lower @ 150 V

Mechanical Equivalence Requirements:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, or Axial configuration

Compliance Requirements:

• Product Status: Active
• Technology: Standard
• RoHS Status: ROHS3 Compliant or equivalent
• REACH Status: REACH Unaffected

The EGP20C from Fairchild Semiconductor meets all specified electrical and mechanical parameters for direct substitution in applications requiring the UG2C-E3/73.

Engineering Selection Recommendations

Primary Selection: UG2C-E3/73 (Vishay General Semiconductor)

The UG2C-E3/73 is the specified component with Active product status and explicit RoHS3 compliance certification. This part is recommended for new designs and applications where Vishay component qualification is required. Current inventory of 4300 pieces supports production requirements.

Substitute Selection: EGP20C (Fairchild Semiconductor)

The EGP20C is qualified as a direct substitute based on electrical parameter equivalence and mechanical compatibility. This part maintains Active product status and REACH unaffected designation. The EGP20C exhibits a higher reverse recovery time (50 ns versus 25 ns) and extended lower operating temperature limit (-65°C versus -55°C), both of which are compatible with the UG2C-E3/73 application envelope. Current inventory of 4613 pieces provides alternative sourcing. RoHS compliance status for the EGP20C is not specified in available documentation; verification against specific procurement requirements is necessary for regulated applications.

Both parts are suitable for general-purpose rectification circuits operating within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can the EGP20C replace the UG2C-E3/73 in existing designs?

A: Yes. The EGP20C meets all critical electrical parameters: 150 V reverse voltage, 2 A average rectified current, 950 mV forward voltage drop at 2 A, and fast recovery characteristics. Both components use identical DO-15 axial through-hole packaging and are mechanically interchangeable.

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

A: The UG2C-E3/73 specifies 25 ns reverse recovery time, while the EGP20C specifies 50 ns. Both fall within the fast recovery classification (≤ 500ns, > 200mA). The longer recovery time of the EGP20C does not affect compatibility in standard rectification applications.

Q: Are both parts RoHS compliant?

A: The UG2C-E3/73 carries explicit RoHS3 compliance certification. The EGP20C RoHS status is not specified in the provided technical data. For applications requiring documented RoHS compliance, the UG2C-E3/73 is the specified choice.

Q: What is the operating temperature range for each part?

A: The UG2C-E3/73 operates from -55°C to 150°C junction temperature. The EGP20C operates from -65°C to 150°C junction temperature. The EGP20C provides extended low-temperature capability; both upper temperature limits are identical.

Q: Are these parts available in different packaging options?

A: Both the UG2C-E3/73 and EGP20C are supplied in DO-204AC (DO-15) axial through-hole packages. The UG2C-E3/73 is available in Bulk packaging, while the EGP20C packaging designation is listed as Bulk. Both are suitable for through-hole PCB assembly.

Q: What is the moisture sensitivity level for these components?

A: The UG2C-E3/73 carries MSL 1 (Unlimited) designation, indicating no moisture sensitivity restrictions. The EGP20C moisture sensitivity level is vendor undefined in the provided data.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Both parts are classified as fast recovery diodes with recovery times well below 500 ns. The EGP20C's 50 ns recovery time is suitable for switching applications within the 2 A current rating. Application-specific circuit analysis is required to confirm suitability for particular switching frequencies.
