MPN Structure

SG Micro MPNs follow this general structure:

[SGM][SERIES][VARIANT][-VOLTAGE][PACKAGE][G][/TR]
  |     |        |        |         |     |   |
  |     |        |        |         |     |   +-- /TR = Tape and Reel
  |     |        |        |         |     +-- G = Green/RoHS
  |     |        |        |         +-- Package code (YN5, XN, YS8, etc.)
  |     |        |        +-- Optional voltage (e.g., -3.3)
  |     |        +-- Variant letter (A, B, etc.)
  |     +-- 4-5 digit series (2xxx, 4xxx, 58xxx, 6xxx, 8xxx)
  +-- SGM = SG Micro prefix

Example Decoding

|  |   |   |  +-- G = RoHS/Green
|  |   |   +-- YN5 = SOT-23-5 package
|  |   +-- 3.3 = 3.3V output voltage
|  +-- 2019 = LDO regulator series
+-- SGM = SG Micro prefix

Handler Implementation Notes

Package Code Extraction

// SG Micro package codes start with Y, X, or U
// Pattern: SGM[0-9]{4,5}[-.]?[voltage]?[package-code]G?(/TR)?
// Extract 2-4 uppercase letters optionally followed by digits

// Remove G and /TR suffixes first
String baseMpn = upperMpn.replaceAll("G?(/TR)?$", "");

// Find package code pattern
Pattern packagePattern = Pattern.compile(".*?([XYUQ][A-Z]*[0-9]*)(?:G?(/TR)?)?$");

Series Extraction

// SGM58xxx is special (5 digits)
// Other series are 4 digits: SGM2xxx, SGM4xxx, SGM6xxx, SGM8xxx

if (upperMpn.startsWith("SGM58") && upperMpn.length() >= 8) {
    return "SGM58";  // High-precision ADC series
}
if (upperMpn.matches("^SGM[0-9][0-9]{3}.*")) {
    return upperMpn.substring(0, 4);  // SGM2, SGM4, SGM6, SGM8
}

Op-Amp vs Comparator Detection

// Op-amps: SGM80xx through SGM85xx
private boolean isOpAmp(String mpn) {
    return mpn.matches("^SGM8[0-5][0-9]{2}[A-Z0-9./-]*$");
}

// Comparators: SGM87xx and higher
private boolean isComparator(String mpn) {
    return mpn.matches("^SGM8[7-9][0-9]{2}[A-Z0-9./-]*$");
}

Voltage in MPN

// Voltage can appear as -3.3 or -3.0 in the MPN
// SGM2019-3.3YN5G/TR -> 3.3V output
// The handler allows dots in MPN patterns: [A-Z0-9./-]*

Product Type Detection

public boolean isLDOPart(String mpn) {
    return mpn.matches("^SGM2[0-9]{3}[A-Z0-9./-]*$");
}

public boolean isDCDCPart(String mpn) {
    return mpn.matches("^SGM6[0-9]{3}[A-Z0-9./-]*$");
}

public boolean isOpAmpPart(String mpn) {
    return mpn.matches("^SGM8[0-5][0-9]{2}[A-Z0-9./-]*$");
}

public boolean isComparatorPart(String mpn) {
    return mpn.matches("^SGM8[7-9][0-9]{2}[A-Z0-9./-]*$");
}

Learnings & Edge Cases

• Voltage in MPN: LDO parts often include output voltage in the MPN (e.g., SGM2019-3.3)
• Dot character in MPN: Pattern must allow dots for voltage codes (3.3V, 1.8V, etc.)
• Package code prefix: Y = SOT/SOIC, X = SC70/MSOP, U = WLCSP
• G suffix: Indicates RoHS/Green compliance, not part of package code
• Op-amp numbering: SGM8051 = single, SGM8262 = dual (similar to industry standard)
• SGM8xxx split: 80-85xx are op-amps, 87-89xx are comparators
• ADC series: SGM58xxx has 5 digits (unlike other 4-digit series)
• Trailing /TR: Common tape and reel suffix, strip before package extraction
• No slash in patterns: Despite /TR suffix, base patterns use [A-Z0-9./-] to handle it
