MPN Structure

Lelon MPNs follow this general structure:

[SERIES]-[CAP_CODE][TOLERANCE][VOLTAGE][TR][PACKAGE]
   |         |         |         |      |      |
   |         |         |         |      |      +-- Package code (0605=6.3x5mm)
   |         |         |         |      +-- TR=Tape and Reel
   |         |         |         +-- Voltage code (1C=16V, 1E=25V)
   |         |         +-- Tolerance (M=20%, K=10%, J=5%)
   |         +-- 3-digit capacitance code (101=100uF)
   +-- Series prefix (VE, VR, VZ, REA, REB, REC, OVZ, OVR)

Example Decoding

VE-101M1CTR-0605
|  |  | | |   |
|  |  | | |   +-- Package: 6.3x5mm
|  |  | | +-- TR = Tape and Reel
|  |  | +-- 1C = 16V
|  |  +-- M = +/-20% tolerance
|  +-- 101 = 100uF (10 x 10^1)
+-- VE = Low Impedance series

REA221M1CTR-0810
|  |  | | |   |
|  |  | | |   +-- Package: 8x10mm
|  |  | | +-- TR = Tape and Reel
|  |  | +-- 1C = 16V
|  |  +-- M = +/-20% tolerance
|  +-- 221 = 220uF (22 x 10^1)
+-- REA = Radial Lead series (no hyphen after prefix)

Series Reference

V-Series (with hyphen)

Series	Description	Application
VE	Low Impedance	Power supply filtering, high ripple current
VR	Standard	General purpose applications
VZ	High Temperature	Automotive, harsh environments

RE-Series (radial lead, no hyphen)

Series	Description	Application
REA	Radial Lead Type A	Through-hole general purpose
REB	Radial Lead Type B	Through-hole standard
REC	Radial Lead Type C	Through-hole compact

OV-Series (polymer, with hyphen)

Series	Description	Application
OVZ	Conductive Polymer Z	Long life, high reliability
OVR	Conductive Polymer R	High ripple current

---

Voltage Codes

Voltage codes appear after capacitance and tolerance codes.

Code	Voltage	Code	Voltage
0G	4V	1H	50V
0J	6.3V	1J	63V
1A	10V	2A	100V
1C	16V	2C	160V
1E	25V	2D	200V
1V	35V	2E	250V
		2G	400V
		2W	450V

---

Capacitance Codes

Uses 3-digit EIA code for electrolytic capacitors (value in uF):

Code	Value	Calculation
100	10uF	10 x 10^0
101	100uF	10 x 10^1
221	220uF	22 x 10^1
470	47uF	47 x 10^0
471	470uF	47 x 10^1
102	1000uF	10 x 10^2

---

Package Codes

Package codes are 4 digits indicating diameter x height in mm (DDLL format):

Code	Dimensions	Code	Dimensions
0405	4x5mm	1012	10x12mm
0505	5x5mm	1016	10x16mm
0605	6.3x5mm	1225	12.5x25mm
0607	6.3x7mm	1315	13x15mm
0810	8x10mm	1620	16x20mm
0811	8x11mm	1825	18x25mm

Handler Implementation Notes

Pattern Recognition

// V-series with hyphen: VE-, VR-, VZ-
"^VE-[0-9]+.*"  // Low impedance
"^VR-[0-9]+.*"  // Standard
"^VZ-[0-9]+.*"  // High temperature

// RE-series without hyphen: REA, REB, REC
"^REA[0-9]+.*"  // Radial lead A
"^REB[0-9]+.*"  // Radial lead B
"^REC[0-9]+.*"  // Radial lead C

// OV-series with hyphen: OVZ-, OVR-
"^OVZ-[0-9]+.*"  // Polymer Z
"^OVR-[0-9]+.*"  // Polymer R

Package Code Extraction

// Package code is the last 4 digits
// VE-101M1CTR-0605 -> 0605 -> 6.3x5mm

// Steps:
// 1. Check last 4 chars for numeric pattern
// 2. Map DDLL to diameter x height
String lastFour = mpn.substring(mpn.length() - 4);
if (lastFour.matches("[0-9]{4}")) {
    // Decode: 06 = 6.3mm diameter, 05 = 5mm height
}

Series Extraction

// Check prefix to determine series type
if (mpn.startsWith("VE-")) return "VE Low Impedance";
if (mpn.startsWith("VR-")) return "VR Standard";
if (mpn.startsWith("VZ-")) return "VZ High Temperature";
if (mpn.startsWith("REA")) return "REA Radial Lead";  // No hyphen
// etc.

Replacement Rules

The handler supports these replacement scenarios:

1. VE can replace VR: Low impedance can replace standard (better performance)
2. VZ can replace VR/VE: High temp can replace standard (wider temp range)
3. OVZ/OVR can replace VR: Polymer can replace standard (longer life)

Package dimensions must match for any replacement.

Learnings & Edge Cases

• Hyphen placement: V-series and OV-series use hyphen after prefix (VE-), but RE-series does not (REA)
• Package code position: Always the last 4 digits of the MPN
• Voltage code position: After capacitance (3 digits) and tolerance (1 letter)
• Tolerance codes: M=20% (most common), K=10%, J=5%
• TR suffix: Indicates tape and reel packaging
