Voltage Extraction
// Determine prefix length first
int startIdx;
if (mpn.startsWith("EKYE") || mpn.startsWith("EKZE") ||
mpn.startsWith("EKXG") || mpn.startsWith("EKXJ") ||
mpn.startsWith("EKMG") || mpn.startsWith("EKMH") ||
mpn.startsWith("ESMG") || mpn.startsWith("ESMH") ||
mpn.startsWith("EMVY") || mpn.startsWith("EMVZ")) {
startIdx = 4; // 4-letter prefix
} else if (mpn.startsWith("EKY") || mpn.startsWith("EKZ") ||
mpn.startsWith("MVY") || mpn.startsWith("MVZ") ||
mpn.startsWith("KMG") || mpn.startsWith("KMH") ||
mpn.startsWith("PSC") || mpn.startsWith("PSE") ||
mpn.startsWith("GXE")) {
startIdx = 3; // 3-letter prefix
}
// Extract 3-digit voltage code
String voltageCode = mpn.substring(startIdx, startIdx + 3);
int voltage = Integer.parseInt(voltageCode) / 10; // 500 -> 50V
Package Code Extraction
// Look for known case code patterns
if (mpn.contains("JC5")) return "5x5.3mm";
if (mpn.contains("JC6")) return "6.3x5.5mm";
if (mpn.contains("MHD")) return "5x11mm";
// etc.
// Or extract M-suffix from end
int lastDigitIdx = findLastDigit(mpn);
String suffix = mpn.substring(lastDigitIdx + 1);
if (suffix.startsWith("M")) return suffix; // MJC5S, MHD, etc.
Replacement Rules
The handler supports replacement scenarios based on:
- Same series required: Different series are not interchangeable
- Package must match: Case size must be identical
- Higher voltage can replace lower: Within same series, 50V can replace 25V
// Higher voltage rating can replace lower in same series
int v1 = parseVoltageCode(voltage1);
int v2 = parseVoltageCode(voltage2);
if (v1 >= v2) return true; // 50V can replace 25V

Learnings & Edge Cases
- Prefix variations: Same series has multiple prefixes (KMG vs EKMG, MVY vs EMVY)
- Voltage format duality: 3-digit (500=50V) and EIA (1V=35V) formats both used
- Case code in suffix: Package info is embedded at end, not separate field
- EK prefix meaning: EK = Nippon Chemi-Con's aluminum electrolytic identifier
- Series code extraction: Need to strip EK/E prefix to get actual series (EKYE -> KY)
- Voltage calculation: 3-digit code divided by 10 gives actual voltage
