         |  |  | ||
         |  |  | |+-- Variant 3
         |  |  | +-- C = Option code
         |  |  +-- D = Differential output
         |  +-- 1612 = 1.6x1.2mm
         +-- KC = Crystal oscillator series

Ceramic Capacitors (CT, CM)

CT[SIZE][VALUE][VOLTAGE][DIELECTRIC]
|   |      |       |         |
|   |      |       |         +-- Dielectric type (X7R, X5R, etc.)

Connectors (5600 series)

[SERIES]-[PINCOUNT]-[VARIANT]
   |         |          |
   |         |          +-- Mounting/option variant
   |         +-- Pin count or configuration
   +-- Series number (5600, 5800, etc.)

Example: 5600-050-141
         |    |   |
         |    |   +-- Variant code
         |    +-- 050 = 50 pins (if applicable)

Replacement Compatibility

Kyocera parts are compatible when:

1. Same series (CX vs CX, KC vs KC)
2. Same package dimensions (3.2x1.5mm matches 3.2x1.5mm)
3. Same frequency (for resonators/oscillators)

Upgrade Paths

• Higher stability resonator can replace standard
• AEC-Q200 qualified can replace non-automotive

Handler Implementation Notes

Pattern Matching

// Ceramic resonators - multiple series
Pattern CX_PATTERN = Pattern.compile("^CX[-]?[0-9]{2,4}[A-Z]*.*", Pattern.CASE_INSENSITIVE);
Pattern CSTS_PATTERN = Pattern.compile("^CSTS[A-Z]*[-]?[0-9]+.*", Pattern.CASE_INSENSITIVE);

// Crystal oscillators
Pattern KC_PATTERN = Pattern.compile("^KC[0-9]{4}[A-Z]*[-]?.*", Pattern.CASE_INSENSITIVE);

// Connectors
Pattern CONNECTOR_PATTERN = Pattern.compile("^5[6-9][0-9]{2}[-]?[0-9]+.*", Pattern.CASE_INSENSITIVE);

Package Code Extraction

// CX resonator: size code is positions 2-3 (or 2-4 after normalizing)
String extractResonatorPackage(String mpn) {
    String normalized = mpn.toUpperCase().replace("-", "");
    if (normalized.length() >= 4) {
        String sizeCode = normalized.substring(2, 4);
        return mapResonatorPackage(sizeCode);
    }
    return "";
}

// KC oscillator: size code is 4 digits after KC
String extractOscillatorPackage(String mpn) {
    String normalized = mpn.toUpperCase().replace("-", "");
    if (normalized.length() >= 6) {
        String sizeCode = normalized.substring(2, 6);
        return mapOscillatorPackage(sizeCode);
    }
    return "";
}

Frequency Extraction

// Frequency may be embedded in MPN or in separate suffix
String extractFrequency(String mpn) {
    String upperMpn = mpn.toUpperCase();
    int lastDash = upperMpn.lastIndexOf('-');
    if (lastDash >= 0 && lastDash < upperMpn.length() - 1) {
        String suffix = upperMpn.substring(lastDash + 1);
        if (suffix.matches(".*[0-9]+.*[MK].*") || suffix.matches(".*[0-9]+.*HZ.*")) {
            return suffix;
        }
    }
    return "";
}

AVX Acquisition Notes

Kyocera acquired AVX Corporation in 2019. Some AVX product lines are now branded under Kyocera AVX:

• Tantalum capacitors
• Ceramic capacitors
• Connectors
• Filters

For AVX-branded parts, use the separate AVX handler.

Learnings & Edge Cases

• Dual branding: Post-acquisition, some parts may be branded "Kyocera AVX" or "AVX (a Kyocera Company)"
• Size code normalization: Remove hyphens before extracting size codes
• Connector pin count: May be encoded in second segment of MPN (e.g., 5600-050-xxx where 050 = 50 pins)
• CSTS 3-terminal: Different pinout than standard 2-terminal resonators
• KC-D differential: Requires differential receiver, not compatible with CMOS inputs
