Use when refactoring, cleaning up, or enhancing the lib-electronic-components codebase. Provides guidance on architecture patterns, known issues, duplication hotspots, and recommended improvements.
Base skill for working with electronic components in this library. Use when adding new component types, manufacturer handlers, or working with MPN (Manufacturer Part Number) operations, BOM entries, or component classification.
Use this skill BEFORE creating a PR to ensure all documentation, skills, and learnings are updated. Critical for preserving institutional knowledge and preventing documentation drift.
Use when working with component similarity calculations - comparing MPNs, finding equivalent parts, implementing new similarity calculators, or understanding how component matching works.
Use when working with capacitor similarity calculations - comparing ceramic/electrolytic/film capacitor MPNs, understanding value/voltage/dielectric matching, or capacitor-specific similarity logic.
Use when working with connector similarity calculations - comparing connector MPNs, understanding pin count/pitch/family matching, or connector-specific similarity logic.

Guidance for working with DiodeSimilarityCalculator in the lib-electronic-components library.
For metadata-driven similarity architecture, see /similarity-metadata:
The DiodeSimilarityCalculator compares diodes based on:
ComponentType.DIODE
// Any type starting with "DIODE_"
Returns false for null type.
HIGH_SIMILARITY = 0.9; // Equivalent parts
MEDIUM_SIMILARITY = 0.7; // Same family, compatible
LOW_SIMILARITY = 0.3; // Same type, different specs
| Group | Members | Notes |
|---|---|---|
| 1N4148/1N914 | 1N4148, 1N914 | Classic signal diodes, equivalent |
calculator.calculateSimilarity("1N4148", "1N914", registry);
// Returns 0.9 (equivalent signal diodes)
| Part | Voltage | Equivalent |
|---|---|---|
| 1N4001 | 50V | RL201 |
| 1N4002 | 100V | RL202 |
| 1N4003 | 200V | RL203 |
| 1N4004 | 400V | RL204 |
| 1N4005 | 600V | RL205 |
| 1N4006 | 800V | RL206 |
| 1N4007 | 1000V | RL207 |
// Same voltage equivalents
calculator.calculateSimilarity("1N4007", "RL207", registry);
// Returns 0.9 (both 1000V rectifiers)
// Same family, different voltage
calculator.calculateSimilarity("1N4001", "1N4007", registry);
// Returns 0.9 (same family, all rectifiers)
calculator.calculateSimilarity("1N4001", "1N4004", registry);
// Returns >= 0.7 (same family)
Zener diodes are compared by voltage rating:
| Part | Voltage |
|---|---|
| 1N4728 | 3.3V |
| 1N4733 | 5.1V |
| 1N4742 | 12V |
| 1N4744 | 15V |
// Same voltage zener
calculator.calculateSimilarity("1N4733", "1N4733", registry);
// Returns 0.9
// Different voltage zeners
calculator.calculateSimilarity("1N4733", "1N4742", registry);
// Returns 0.3 (5.1V vs 12V - not interchangeable)
| Group | Members |
|---|---|
| BAT54 | BAT54, BAT54S (series dual) |
calculator.calculateSimilarity("BAT54", "BAT54S", registry);
// Returns 0.9 (same Schottky, different configuration)
// Equivalent signal diodes
calculator.calculateSimilarity("1N4148", "1N914", registry);
// Returns 0.9
// Same rectifier diode
calculator.calculateSimilarity("1N4007", "1N4007", registry);
// Returns 0.9
// Cross-manufacturer rectifier
calculator.calculateSimilarity("1N4007", "RL207", registry);
// Returns 0.9
// Same zener voltage
calculator.calculateSimilarity("1N4733", "1N4733", registry);
// Returns 0.9
// Different zener voltage
calculator.calculateSimilarity("1N4733", "1N4742", registry);
// Returns 0.3
// Non-diode parts
calculator.calculateSimilarity("LM358", "LM324", registry);
// Returns 0.0
