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

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
}

Voltage Options (LDO Regulators)
LDO regulators often have voltage options encoded as suffix:
| Suffix |

| -5 |
5.0V |
| -33 |
3.3V |
| -25 |
2.5V |
| -18 |
1.8V |
| -12 |
1.2V |
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
