LM35 = Temperature sensor (letter A-D after "35") LM358 = Dual op-amp (digit 8 after "35")
LM35DZ → Temperature sensor (D = grade, Z = TO-92 package)
LM358N → Dual op-amp (8 = part of series, N = DIP package)
Handler Pattern:
// LM35 sensors: letter A-D immediately after "35"
"^LM35[A-D][A-Z0-9-]*$"
// LM358 op-amps: digit after "35"
"^LM358[A-Z0-9]*(?:N|D|P|DG|PW)?$"
78xx = Positive voltage regulator 79xx = Negative voltage regulator
LM7805CT → +5V regulator, TO-220
LM7905CT → -5V regulator, TO-220

// TI package codes come AFTER the base part number
// Example: LM358D → base="LM358", package="D"
// For voltage regulators, package often follows voltage
// Example: LM7805CT → base="LM7805", package="CT" (TO-220)
// CRITICAL: Check longer suffixes BEFORE shorter ones!
// "LM7805DT".endsWith("T") is TRUE, but DT=SOT-223, not TO-220
if (suffix.endsWith("CT")) return "TO-220"; // 2-char first
if (suffix.endsWith("DT")) return "SOT-223"; // 2-char first
if (suffix.endsWith("MP")) return "SOT-223"; // 2-char first
if (suffix.endsWith("KC")) return "TO-252"; // 2-char first
if (suffix.endsWith("T")) return "TO-220"; // 1-char LAST
// Same for SOIC vs MSOP vs TSSOP
if (suffix.startsWith("DGK")) return "MSOP"; // 3-char first
if (suffix.startsWith("PW")) return "TSSOP"; // 2-char
if (suffix.startsWith("D")) return "SOIC"; // 1-char LAST
Bug Example (Fixed in PR #78):
// WRONG - "DT" ends with "T" so this returns TO-220 incorrectly
if (upperMpn.endsWith("T")) return "TO-220"; // Matches first!
if (upperMpn.endsWith("DT")) return "SOT-223"; // Never reached
// CORRECT - Check longer suffixes first
if (upperMpn.endsWith("DT")) return "SOT-223"; // Matches correctly
if (upperMpn.endsWith("T")) return "TO-220"; // Only bare "T"
// Extract base series before package/temperature suffix
// LM358APWRQ1 → LM358 (ignore A=variant, PW=package, R=tape, Q1=automotive)
// Voltage regulators include voltage in series
// LM7805 → full series is "LM7805" not just "LM78"
manufacturers/TIHandler.javaOPAMP_TI, VOLTAGE_REGULATOR_LINEAR_TI, VOLTAGE_REGULATOR_SWITCHING_TI, TEMPERATURE_SENSOR_TI, LED_TIPackageCodeRegistry.java (standard codes)endsWith() for package detection, ALWAYS check longer suffixes first. "DT" ends with "T", so checking "T" first causes wrong results.handlers package, NOT manufacturers package (causes classpath shadowing)MPNUtils.getManufacturerHandler("LM358") in tests, not new TIHandler() (causes circular init)
