MPN Structure Coilcraft MPNs follow this general structure: ``` [SERIES][SIZE][-][VALUE][TOLERANCE][PACKAGING] | | | | | | | | | | | +-- E=Embossed tape, B=Bulk | | | | +-- M=+/-20%, L=+/-15%, K=+/-10% | | | +-- 3-digit inductance code (or Rxx for sub-uH) | | +-- Optional hyphen separator | +-- 4-digit size code (e.g., 4020 = 4.0mm x 2.0mm) +-- Series prefix (XAL, XEL, XFL, SER, LPS, MSS, DO, MSD, SLC, SLR) ``` ### Example Decoding ``` XAL4020-222ME | | | || | | | |+-- E = Embossed tape packaging | | | +-- M = +/-20% tolerance | | +-- 222 = 2.2uH (see value code section) | +-- 4020 = 4.0mm x 2.0mm footprint +-- XAL = Shielded power inductor series LPS3015-103MLB | | | ||| | | | ||+-- B = Bulk packaging | | | |+-- L = +/-15% tolerance | | | +-- M = +/-20% (sometimes double suffix for different specs) | | +-- 103 = 10uH | +-- 3015 = 3.0mm x 1.5mm footprint +-- LPS = Low Profile Shielded series ``` --- ##

Supported Component Types The CoilcraftHandler supports: - `ComponentType.INDUCTOR` - Base inductor type - `ComponentType.INDUCTOR_CHIP_COILCRAFT` - Coilcraft-specific inductor type --- ## Example MPNs with Full Decoding ### XAL4020-222ME ``` Series: XAL (Shielded Power Inductor) Size: 4020 (4.0mm x 4.0mm x 2.0mm) Inductance: 222 = 22 x 10^2 nH = 2.2 uH Tolerance: M = +/- 20% Packaging: E = Embossed tape Full Series: XAL4020 Package: Shielded Power ``` ### XEL4030-102MRB ``` Series: XEL (Shielded Low DCR) Size: 4030 (4.0mm x 4.0mm x 3.0mm) Inductance: 102 = 10 x 10^2 nH = 1.0 uH Tolerance: M = +/- 20% Options: R = Tape, B = (possibly bulk variant) Full Series: XEL4030 Package: Shielded Low DCR ``` ### LPS3015-103MLB ``` Series: LPS (Low Profile Shielded) Size: 3015 (3.0mm x 3.0mm x 1.5mm) Inductance: 103 = 10 x 10^3 nH = 10 uH Tolerance: L = +/- 15% Packaging: B = Bulk Full Series: LPS3015 Package: Low Profile Shielded ``` ### 0402HP-R47KB ``` Series: 0402HP (0402 High Performance) Inductance: R47 = 0.47 uH Tolerance: K = +/- 10% Packaging: B = Bulk Full Series: 0402HP Package: 0402 High Performance ``` ### DO3316P-472MLB ``` Series: DO (Drum Core) Size: 3316 (3.3mm x 3.3mm x 1.6mm) Variant: P = Power variant Inductance: 472 = 47 x 10^2 nH = 4.7 uH Tolerance: L = +/- 15% Packaging: B = Bulk Full Series: DO3316P Package: Drum Core ``` --- ## Handler Implementation Notes ### Pattern Matching ```java // Coilcraft patterns have consistent structure: // - 2-3 letter series prefix // - 4-digit size code // - Optional hyphen // - 3-digit value code (or Rxx) // - Optional tolerance + packaging suffix // Example pattern for XAL/XEL series: "^(XA[LT]|XEL)(\\d{4})[-]?(\\d{3}|R\\d{2})([A-Z]*)$" // | | | | | // | | | | +-- Suffix group (tolerance+pkg) // | | | +-- Value group (222 or R47) // | | +-- Optional hyphen // | +-- Size code group (4 digits) // +-- Series group ``` ### Inductance Value Extraction The handler includes `extractInductanceValue()` method that: 1. Matches the MPN against series patterns 2. Extracts the 3-digit value code 3. Parses using standard EIA notation or R-notation 4. Returns formatted string (e.g., "2.2uH", "470nH") ### Official Replacement Check Two Coilcraft parts are considered official replacements if: 1. Same series (including size) - e.g., both XAL4020 2. Same inductance value - e.g., both 2.2uH Different tolerance or packaging options are compatible replacements. --- ## Related Files - Handler: `manufacturers/CoilcraftHandler.java` - Component types: `INDUCTOR`, `INDUCTOR_CHIP_COILCRAFT` - Tests: Check for `CoilcraftHandlerTest.java` in handlers package --- ## Learnings & Edge Cases - **Hyphen is optional**: MPNs may appear as `XAL4020-222ME` or `XAL4020222ME` - **Suffix variations**: Tolerance + packaging may appear in various orders (ME, MEB, MRB) - **DO series variant suffix**: The C/P/T letter after the size code indicates design variant, not tolerance - **HP series different structure**: 0402HP and 0603HP don't have a separate size code - the size IS the series prefix - **R-notation case sensitivity**: While the handler is case-insensitive, R-notation typically appears uppercase - **Value code group extraction**: For DO pattern, the value code is in group 4 (not group 3) due to the extra variant suffix group - **Series includes size for uniqueness**: `extractSeries()` returns "XAL4020" not just "XAL" because different sizes have different current ratings ### Pattern Group Numbering Different series have different regex group structures: ``` XAL/XEL/XFL/SER/LPS/MSS/MSD/SLC/SLR patterns: Group 1: Series prefix (XAL) Group 2: Size code (4020) Group 3: Value code (222) Group 4: Suffix (ME) DO pattern (has extra variant group): Group 1: Series prefix (DO) Group 2: Size code (3316) Group 3: Variant suffix (P) Group 4: Value code (472) Group 5: Suffix (MLB) HP pattern (no separate size): Group 1: Series+size (0402HP) Group 2: Value code (R47) Group 3: Suffix (KB) ```
