Specs side by side
2 parts compared · 14 differing specs across 14 total parameters.
| Parameter | ||
|---|---|---|
| Supply voltage | Per the replacement datasheet; the rails of the original design define the requirement. | - |
| Memory & Peripherals | For service work, the NTE route is a datasheet with a substitution statement - useful when the original marking is the only documentation available. | - |
| Case | Hybrid replacement | Thick-film hybrid (SIP) |
| Compatibility Level | Functional Equivalent | - |
| Component Category | - | Audio Power Amplifiers (Hybrid Modules) |
| Core & Architecture | The NTE/ECG-line replacement listed against the Sanyo hybrid audio modules of this class - a replacement-brand channel rather than a pin twin. | - |
| Firmware Notes | Verify the replacement datasheet against the original rails and gain: the NTE line spans many modules and the equivalence grade varies. It is a documented lead, not an automatic fit. | - |
| Hardware Notes | Form factor varies - check the mounting before committing. | - |
| Lead Time Advantage | Shenzhen Spot Stock (24-48h Dispatch) | - |
| Market Reality | - | The Sanyo STK thick-film modules powered a generation of Japanese and European hi-fi: a complete two-channel class-AB power stage on a ceramic substrate, bolted to the heatsink, no adjustment, no discrete matching - the appeal that made them everywhere and the reason the mid-2000s discontinuation left thousands of amplifiers unserviced. What remains is one of the worst counterfeit markets in analog audio: genuine Sanyo stock is old and finite, and the reproduction modules are identifiable by substrate and mask details that repair forums documented long before this page. The substitution path is equally documented: the higher-power members of the same series share the pinout with a two-pin bridge at the input end. |
| Reference Part | STK403-070 | - |
| Role In Circuit | - | Original Reference Part |
| Sourcing Advantage | Documented cross-reference line for legacy service. | - |
| Sourcing Status | - | Active Shenzhen Spot Sourcing (24–48h) |
