Frequently Asked Questions (FAQ)

Q: Can the EGP10C replace the UG1C-E3/54 in existing designs?

A: Yes. The EGP10C meets all electrical equivalence criteria: 150 V reverse voltage, 1 A average rectified current, 950 mV forward voltage drop at 1 A, and fast recovery speed classification. Both components use identical DO-204AL (DO-41) axial through-hole packaging and are mechanically interchangeable on printed circuit boards.

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

A: The UG1C-E3/54 specifies 25 ns reverse recovery time, while the EGP10C specifies 50 ns. Both values satisfy the fast recovery classification (≤ 500ns, > 200mA). The difference does not affect substitution eligibility for standard general-purpose rectifier applications.

Q: Are there packaging differences between these parts?

A: The UG1C-E3/54 is supplied in Tape & Reel (TR) packaging, while the EGP10C is supplied in Bulk packaging. Both components use the same DO-204AL (DO-41) axial case style and are physically identical for circuit board installation. Packaging selection depends on assembly process requirements.

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

A: The UG1C-E3/54 operates from -55°C to 150°C junction temperature. The EGP10C operates from -65°C to 150°C junction temperature. The EGP10C provides extended low-temperature capability, which may be advantageous in applications requiring operation below -55°C.

Q: Are both parts RoHS compliant?

A: Yes. The UG1C-E3/54 is RoHS3 Compliant and REACH Unaffected. The EGP10C is RoHS3 Compliant. Both parts meet current environmental compliance requirements for electronic component manufacturing and use.

Q: What is the reverse leakage current specification?

A: Both the UG1C-E3/54 and EGP10C specify 5 µA maximum reverse leakage current at 150 V. This parameter is identical across both parts and does not affect substitution decisions.

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

A: Both parts are classified as fast recovery diodes with recovery times within the fast recovery specification. The UG1C-E3/54 at 25 ns and EGP10C at 50 ns are suitable for general-purpose rectification and moderate-frequency switching applications within the 1 A current rating.
