MPN Structure

Abracon MPNs follow this general structure:

[PREFIX][SIZE][VARIANT]-[FREQUENCY]-[OPTIONS]
   |      |       |          |          |
   |      |       |          |          +-- Stability, tolerance, temp grade
   |      |       |          +-- Frequency in MHz (oscillators) or kHz (crystals)
   |      |       +-- Variant letter/number
   |      +-- Size code (02, 03, 07, 08, 10, etc.)
   +-- Product family (ABM, ABL, ASE, etc.)

Supported ComponentTypes

The AbraconHandler supports these component types:

Note: Some types are declared in getSupportedTypes() but may not have corresponding patterns registered in initializePatterns().

Handler Implementation Details

Package Code Extraction

// Crystals: Extract size code at positions 3-4 after prefix
// ABM03-... -> "03" -> "3.2 x 2.5mm"
String sizeCode = upperMpn.substring(3, 5);

// Oscillators: Package code comes after dash
// ASCO-12.000MHZ-E-T -> "E" -> "5.0 x 3.2mm"
int dashIndex = upperMpn.indexOf('-');
String pkgCode = upperMpn.substring(dashIndex + 1, dashIndex + 3);

// Inductors: Size code at positions 4-5
// AIAL02-... -> "02" -> "0201"
String sizeCode = upperMpn.substring(4, 6);

Series Extraction

The handler returns human-readable series names:

Replacement Compatibility

The isOfficialReplacement() method checks:

1. Same series (e.g., both "Standard Crystal")
2. Same package size
3. Same frequency
4. Compatible stability grade (lower PPM can replace higher PPM)

// Stability compatibility: lower PPM (tighter tolerance) can replace higher
// Example: 10PPM crystal can replace 20PPM crystal
int ppm1 = Integer.parseInt(stability1.replace("PPM", ""));
int ppm2 = Integer.parseInt(stability2.replace("PPM", ""));
return ppm1 <= ppm2;  // Lower is better, can replace higher

Learnings & Quirks

Handler Issues (Known)

1. HashSet in getSupportedTypes(): Uses mutable HashSet instead of Set.of(). Should be modernized.

2. Type/Pattern Mismatch: getSupportedTypes() declares these types that have NO patterns registered:

   • OSCILLATOR_OCXO_ABRACON - no OCXO patterns
   • CLOCK_ABRACON - no clock patterns
   • ANTENNA_ABRACON - no antenna patterns (but ABA* registered as IC)
   • RF_FILTER_ABRACON - no filter patterns (but ABF* registered as IC)

3. RF Products Registered as IC: Antennas (ABA), filters (ABF), baluns (ABB), and diplexers (ABUN) are registered under ComponentType.IC instead of their specific types.

4. VCXO Pattern Mismatch: The pattern for OSCILLATOR_VCXO_ABRACON uses ^ASXV[0-9].* but the base OSCILLATOR type uses ^ASV[0-9].* (note ASXV vs ASV).

MPN Pattern Notes

• All Abracon crystal/oscillator MPNs start with "AB" or "AS"
• Frequency is typically after the first dash
• Size code position varies by product family:
  • Crystals (ABM/ABL): positions 3-4
  • Inductors (AIAL/AIML): positions 4-5
  • Oscillators: after dash in options section

Replacement Part Guidance

• Crystals with tighter tolerance (lower PPM) can replace looser tolerance parts
• Must match: frequency, package size, load capacitance
• Consider: temperature grade (automotive needs AEC-Q200)

Testing Notes

• No existing test file for AbraconHandler (listed in "Handlers Without Tests")
• When creating tests, use package no.cantara.electronic.component.lib.handlers (NOT manufacturers)
• Test frequency extraction, package code mapping, and series identification
