MPN Structure

Nippon Chemi-Con MPNs follow this general structure:

[PREFIX][SERIES][VOLTAGE][SUFFIX][CAP_CODE][CASE_SIZE]
   |       |        |       |        |         |
   |       |        |       |        |         +-- Case code (MJC5S, MHD, etc.)
   |       |        |       |        +-- 3-digit capacitance code (101=100uF)
   |       |        |       +-- Internal code (ELL, etc.)
   |       |        +-- 3-digit voltage (500=50V) or digit+letter (1C=16V)
   |       +-- Series code (YE, ZE, XG, etc.)
   +-- EK/E/M prefix (aluminum electrolytic prefix)

3-Digit Format (Primary)

Nippon Chemi-Con primarily uses 3-digit voltage codes where value = code / 10:

EIA Letter Format (Alternate)

Some series use EIA voltage codes (digit + letter):

Capacitance Codes

Uses standard EIA 3-digit code (value in uF):

Case Size Codes

SMD Case Codes

Radial Lead Case Codes

Pattern Recognition

// KY series - Low impedance

"^EKYE[0-9]{3}.*"      // Alternate
"^EKY[0-9][A-Z].*"     // EIA voltage format

// KZE series - Polymer hybrid
"^EKZ[A-Z][0-9]{3}.*"  // EKZE250...
"^EKZE[0-9]{3}.*"      // Alternate

// Generic patterns
"^EK[A-Z]{2}[0-9]{3}.*"    // Any EK + 2 letters + 3-digit voltage
"^M[A-Z]{2}[0-9]{3}.*"     // Any M + 2 letters + 3-digit voltage

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:

1. Same series required: Different series are not interchangeable
2. Package must match: Case size must be identical
3. 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
