Supported Component Types

The NexteriaHandler supports these ComponentTypes:

Base Types

• MOSFET
• TRANSISTOR
• DIODE
• IC

Nexperia-Specific Types

• MOSFET_NEXPERIA
• BIPOLAR_TRANSISTOR_NEXPERIA
• ESD_PROTECTION_NEXPERIA
• LOGIC_IC_NEXPERIA

Series Extraction Rules

The handler extracts series using these patterns:

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
);

• Component types: MOSFET_NEXPERIA, BIPOLAR_TRANSISTOR_NEXPERIA, ESD_PROTECTION_NEXPERIA, 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
