Supported Component Types The handler supports these `ComponentType` values: | Type | Description | Families | |------|-------------|----------| | `IC` | Generic IC classification | All families | | `VOLTAGE_REGULATOR` | Power conversion IC | All families | **Note**: Power Integrations parts are classified as `VOLTAGE_REGULATOR` since they perform AC-DC conversion and voltage regulation functions, even though they are technically more complex SMPS controllers. --- ## Handler Implementation Notes ### Package Code Extraction ```java // Extract suffix after the last digit // TOP249YN → YN // INN3673C → C // Check longer suffixes FIRST (e.g., "KG" before "K", "YN" before "Y") for (int len = Math.min(suffix.length(), 2); len >= 1; len--) { String candidate = suffix.substring(0, len); if (PACKAGE_CODES.containsKey(candidate)) { return PACKAGE_CODES.get(candidate); // Returns decoded name, not code } } ``` **Key Point**: The handler returns the decoded package name (e.g., "TO-220") not the raw code (e.g., "Y"). ### Series Extraction ```java // Extract 3-letter prefix if (upperMpn.startsWith("TOP")) return "TOP"; if (upperMpn.startsWith("TNY")) return "TNY"; if (upperMpn.startsWith("LNK")) return "LNK"; if (upperMpn.startsWith("INN")) return "INN"; if (upperMpn.startsWith("PFS")) return "PFS"; if (upperMpn.startsWith("LCS")) return "LCS"; if (upperMpn.startsWith("CAP")) return "CAP"; if (upperMpn.startsWith("SEN")) return "SEN"; ``` ### Product Family Helper The handler provides `getProductFamily(String mpn)` to get the marketing name: | Series | Family Name | |--------|-------------| | TOP | TOPSwitch | | TNY | TinySwitch | | LNK | LinkSwitch | | INN | InnoSwitch | | PFS | HiperPFS | | LCS | HiperLCS | | CAP | CAPZero | | SEN | SENZero | ### Base Part Number Extraction ```java // extractBasePartNumber() returns series + number without package suffix // TOP249YN → TOP249 // INN3673CJ → INN3673 // TNY268GN → TNY268 ``` ### Replacement Compatibility `isOfficialReplacement()` checks: 1. Same product family (series prefix) 2. Same base part = same part, different package (always compatible) 3. Same sub-family (first 4 chars) with numeric difference <= 10 ```java // Same base part, different package = compatible TOP249Y and TOP249YN → true (same part) // Same sub-family, close numbers = potentially compatible TOP223Y and TOP224Y → true (within 10) TOP223Y and TOP249Y → false (26 apart) ``` --- ## Pattern Matching Details ### Registered Patterns ``` TOPSwitch: ^TOP[23][0-9]{2}[A-Z0-9]*$ TinySwitch: ^TNY[23][0-9]{2}[A-Z0-9]*$ LinkSwitch: ^LNK[346][0-9]{2}[A-Z0-9]*$ InnoSwitch: ^INN[234]0[0-9]{2}[A-Z0-9]*$ and ^INN3[0-9]{3}[A-Z0-9]*$ HiperPFS: ^PFS7[0-9]{2}[A-Z0-9]*$ HiperLCS: ^LCS7[0-9]{2}[A-Z0-9]*$ CAPZero: ^CAP0[0-9]{2}[A-Z0-9]*$ SENZero: ^SEN0[0-9]{2}[A-Z0-9]*$ ``` ### Explicit matches() Implementation The handler implements explicit pattern matching in `matches()` rather than relying solely on registry lookup. This provides: - Better performance (direct regex) - More predictable behavior - Explicit fallback to registry --- ## Example MPN Reference | MPN | Family | Base Part | Package | Notes | |-----|--------|-----------|---------|-------| | TOP223Y | TOPSwitch | TOP223 | TO-220 | Entry-level TOPSwitch | | TOP249YN | TOPSwitch | TOP249 | TO-220 | High-power TOPSwitch |
