For detailed implementation, the provides the necessary technical specifications, including: Pin Configurations: Detailed diagrams of the DIP-8 layout.
| Replacement Part | Manufacturer | Specs | Why it works | | :--- | :--- | :--- | :--- | | 1N4004 | Multiple | 1A, 400V | Under-rated for 2A. Use only for <1A apps. | | 1N5404 | Multiple | 3A, 400V | Excellent substitute: higher current, same package. | | FR204 | Multiple | 2A, 400V, 150ns | Fast recovery – works but unnecessary. Check price. | | S2B | Diodes Inc. | 2A, 100V | Voltage too low (100V < 155V). Do NOT use. | | S2D | Diodes Inc. | 2A, 200V | Surface mount. Perfect for SMB package. | | HER204 | Multiple | 2A, 300V, 50ns | High-efficiency replacement. | 2a155d datasheet
