Series Extraction Rules

The handler extracts series using these patterns:

| Pattern | Extracted Series | |---------|------------------| | PSMN* | "PSMN" | | PSMP* | "PSMP" | | PMV* | "PMV" | | BSS* | "BSS" | | 2N7002* | "2N7002" | | PMBT* | "PMBT" | | PBSS* | "PBSS" | | BC5xx* | "BC5xx" | | BC8xx* | "BC8xx" | | BC* | "BC" | | BF* | "BF" | | MMBT* | "MMBT" | | PMEG* | "PMEG" | | BAVxx* | Specific (e.g., "BAV99") | | BATxx* | Specific (e.g., "BAT54") | | BZXxx* | Specific (e.g., "BZX84") | | 74family* | Family (e.g., "74LVC", "74AHC") | | PCA* | "PCA" | | PCF* | "PCF" | | PTN* | "PTN" |

Package Code Extraction Logic

Step 1: Check for Comma-Separated Suffix

// Nexperia uses ,215, ,315, etc. for tape & reel packaging
if (mpn.contains(",")) {
    String suffix = mpn.substring(mpn.indexOf(',') + 1);
    // Lookup in NEXPERIA_PACKAGES map
}

Step 2: Series-Specific Extraction

Power MOSFETs (PSMN/PSMP):

Extract letter suffix after last digit
T=LFPAK56, U=LFPAK88, V=LFPAK33, B=SOT754, L=TO-220

Small Signal (PMV/BSS/2N7002):

Extract suffix after last digit
Lookup in package map or return default SOT23

Transistors (PMBT/PBSS):

Single letter suffix after grade letter = default SOT23
Multi-letter suffix = lookup in map

Zener Diodes (BZX):

BZX84 = SOT23
BZX384 = SOD323
BZX55/79 = DO-35
BZX85 = DO-41

Signal Diodes (BAV/BAS/BAT):

Most default to SOT23

Schottky Rectifiers (PMEG):

Suffix-based: AEH=SOD123, AED=SOD323F, BEA=SOD128

ESD Protection (PESD):

BL=SOD882, BA=SOD323, UB=SOT23, UD=SOT323

Logic ICs (74xxx):

GW=SOT353, GM=XSON6, BQ=DHVQFN, PW=TSSOP, D=SO14
Also handles underscore format: 74HC00_D

Official Replacement Rules

The handler supports isOfficialReplacement() for:

Logic ICs

Same function number across families are compatible
HCT is backward compatible with HC
Same family, different packages are compatible

Transistors

PMBT2222A, 2N2222, PN2222 are equivalent (base "2222")
PMBT3904 and 2N3904 are equivalent
PMBT3906 and 2N3906 are equivalent

MOSFETs

Same base part, different package = compatible
e.g., PSMN013-30YL and PSMN013-30YT (same specs, different packages)

Handler Implementation Notes

MPN Normalization

// Remove tape & reel suffix before pattern matching
private String normalizeForMatching(String mpn) {
    if (mpn.contains(",")) {
        return mpn.substring(0, mpn.indexOf(','));
    }
    return mpn;
}

Pattern Matching

The handler overrides matches() with explicit checks to avoid cross-handler false matches. It does NOT fall back to the PatternRegistry default implementation.

Supported Types Use Set.of()

return Set.of(
    ComponentType.MOSFET,
    ComponentType.TRANSISTOR,
    ComponentType.DIODE,
    ComponentType.IC,
    ComponentType.MOSFET_NEXPERIA,
    ComponentType.BIPOLAR_TRANSISTOR_NEXPERIA,
    ComponentType.ESD_PROTECTION_NEXPERIA,
    ComponentType.LOGIC_IC_NEXPERIA
);

Learnings & Quirks

Handler Filename Typo

The file is named NexteriaHandler.java but the manufacturer is Nexperia
This is documented in the class-level Javadoc comment
All ComponentTypes use the correct "NEXPERIA" suffix

Comma-Separated Package Codes

Unlike most manufacturers, Nexperia uses comma-separated suffixes (,215, ,315)
These MUST be stripped before pattern matching
The comma suffix encodes both package AND tape/reel configuration

Logic IC Families

When extracting logic family, check longer prefixes first: AHCT before AHC, LVCH before LVC
The extractLogicFamily() method iterates through families in correct order

Package Extraction Complexity

Different series have completely different package encoding schemes
PMEG uses full suffix codes (AEH, AED), while PSMN uses single letters (T, U, V)
BZX series encodes package in the series name itself (BZX84 = SOT23)

Transistor Equivalents

PMBT2222A = 2N2222A = PN2222A (same transistor, different packages)
The handler correctly identifies these as equivalent in isOfficialReplacement()

No ManufacturerComponentTypes

getManufacturerTypes() returns Collections.emptySet()
All types are standard ComponentType enums

Pattern Registration

Each pattern is registered for BOTH base type and Nexperia-specific type
Example: MOSFET and MOSFET_NEXPERIA both get the PSMN pattern
