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:

Prefix	Returned Series
ABM	"Standard Crystal"
ABL	"Low Profile Crystal"
ABT	"Tuning Fork Crystal"
ABS	"Automotive Crystal"
ASCO	"Standard Oscillator"
ASFL	"Low Power Oscillator"
ASE	"EMI Reduced Oscillator"
ASTX	"TCXO"
ASVTX	"VCTCXO"
ASV	"VCXO"
ABA	"RF Antenna"
ABF	"RF Filter"
ABB	"RF Balun"
ABUN	"RF Diplexer"
AIAL	"Air Core Inductor"
AIML	"Multilayer Inductor"
AIRP	"Power Inductor"

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
