Prolific Technology MPN encoding patterns, variant identification, and handler guidance. Use when working with USB interface ICs or ProlificHandler.
Prolific MPNs follow this general structure:
PL[SERIES][VARIANT][PACKAGE][-REEL]
| | | | |
| | | | └── Optional: REEL, TUBE, TRAY, TR for packaging
| | | └── Package code (implicitly determined by variant for PL2303)
| | └── Variant letters (HX, HXA, HXD, TA, GT, GC, GL, RA, SA, etc.)
| └── 4-digit series number (23xx, 25xx, 27xx, 38xx)
└── PL = Prolific prefix
PL2303HXA-SSOP
│ │ │ │
│ │ │ └── SSOP package
│ │ └── HXA = Enhanced HX variant
│ └── 2303 = USB to serial converter
└── PL = Prolific prefix
PL2303GT
│ │ │
│ │ └── GT = QFN package variant
│ └── 2303 = USB to serial converter
└── PL = Prolific prefix
