MPN Structure

3PEAK MPNs follow this general structure:

TP[SERIES][VARIANT]-[PACKAGE][OPTIONS]
│    │       │         │        │
│    │       │         │        └── Optional: voltage options (-5, -33)
│    │       │         └── Package code (TR, QR, MR, DR)
│    │       └── Part number within series
│    └── Series (1xxx=Op-Amp, 2xxx=Precision, 5xxx=ADC, 7xxx=LDO, 1xx=Current Sense)
└── 3PEAK prefix

Example Decoding

TP1541-TR
│  │   │
│  │   └── TR = SOT-23 package, Tape & Reel
│  └── 1541 = Op-Amp series
└── TP = 3PEAK prefix

TP7150-MR-33
│  │   │  │
│  │   │  └── -33 = 3.3V output option
│  │   └── MR = MSOP package
│  └── 7150 = LDO regulator series
└── TP = 3PEAK prefix

Package Codes

Product Series

Op-Amps (TP1xxx, TP2xxx)

Comparators (TP1xxx, TP2xxx)

LDO Voltage Regulators (TP7xxx)

ADCs (TP5xxx)

Current Sense Amplifiers (TP1xx)

Handler Implementation Notes

Component Type Detection

The handler distinguishes between similar-looking part numbers:

// Op-amps have 4-digit part numbers (TP1541, TP2111)
// Current sense amps have 3-digit part numbers (TP181, TP182)
// Comparators share prefix but have specific part numbers (TP1561, TP2345)

// CRITICAL: Comparators must be excluded from op-amp detection
if (COMPARATOR_PATTERN.matcher(mpn).matches()) {
    return false; // Not an op-amp
}

Package Code Extraction

// Package code is the 2-letter suffix after the part number
// TP1541-TR -> TR = SOT-23
// TP7150MR  -> MR = MSOP (no hyphen variant)

// Remove voltage options before extracting package
String baseMpn = upperMpn.replaceAll("-[0-9]+$", "");

Series Extraction

// Current sense amps: TP18x -> "TP18"
// Standard 4-digit: TP1541 -> "TP1"
// Standard 4-digit: TP7150 -> "TP7"

if (upperMpn.matches("^TP18[0-9].*")) {
    return "TP18";  // Special case for current sense
}

Series Descriptions

Voltage Options (LDO Regulators)

LDO regulators often have voltage options encoded as suffix:

Learnings & Edge Cases

• 3-digit vs 4-digit parts: TP181 (3-digit) is current sense amplifier, TP1541 (4-digit) is op-amp
• Comparator exclusion: TP1561 and TP2345 are comparators, NOT op-amps, despite similar prefixes
• Package code hyphen: Both TP1541-TR and TP1541TR formats are valid
• Voltage option suffix: -33 means 3.3V output, not package variation
