NSi1200-DDBR is the closest listed electrical match for AMC1200SDUBR.
AMC1200SDUBR replacements should be treated as design-review candidates. The closest listed match is NSi1200-DDBR, but pinout evidence is still missing.
gain, input range, and supply must match
DUB/SOIC labels need footprint proof
analog part; ADC scaling may change
lifecycle fields are limited
No verified pin-compatible replacement is supported by the provided data.
Check NSi1200-DDBR first, then Pai8300E-W5R; use AMC1302DWVR only with redesign.
Pinout and package evidence are incomplete.

NSi1200-DDBR is the closest listed electrical match for AMC1200SDUBR.
| Feature / factor | AMC1200SDUBR | NSi1200-DDBR | Pai8300E-W5R | AMC1302DWVR | Compatibility / risk |
|---|---|---|---|---|---|
| Application | shunt current iso amp | shunt current iso amp | shunt current iso amp | shunt current iso amp | shunt current iso amp — same role; Pai8300E-W5R: same use; AMC1302DWVR: same role |
| Voltage | 4000VPEAK | 5000Vrms | 3.0-5.5V supply | 5000Vrms | 5000Vrms / 3.0-5.5V supply — unit standard check; Pai8300E-W5R: covers 5V; AMC1302DWVR: unit standard check |
| Package | SOP-8(DUB) | DUB8 | WB SOIC-8 | SOIC-8 | DUB8 / WB SOIC-8 — name close; Pai8300E-W5R: layout check; AMC1302DWVR: not proven fit |
| Pinout | 8 pins | 8 pins | 8 pins | 8 pins | 8 pins — functions absent; Pai8300E-W5R: functions absent; AMC1302DWVR: functions absent |
NSi1200-DDBR is the closest listed candidate, but it still needs pinout, supply, and nonlinearity review.
