PIC16LC Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
PIC16LC is a Microchip Technology order-code family — not a single orderable MPN. This page lists 10 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
IC MCU 8BIT 3.5KB OTP 18SOIC Other listed variants describe: Package: 44-LCC (J-Lead) | Mounting Type: Surface Mount | Operating Temperature: 0°C ~ 70°C (TA) | Supplier Device Package: 44-PLCC (16.59x16.59) | Peripherals: Brown-out Detect/Reset, POR, PWM, WDT | Number of I O: 33; IC MCU 8BIT 7KB OTP 44PLCC.
Across listed variants, watch these parameters: packages: 44-LCC (J-Lead).
Suffix examples in this family: 558-04/SO, 64A-04/L, 65B-04/L, 65B-04I/P, 67-04I/PQ, 71-04I/SO, 73A-04/SP, 74B-04I/PQ. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: PIC16LC558-04/SO, PIC16LC64A-04/L, PIC16LC65B-04/L, PIC16LC65B-04I/P, PIC16LC67-04I/PQ, PIC16LC71-04I/SO.
Key Features
- Footprint / package: 44-LCC (J-Lead)Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 10 distinct suffix patternsExamples: 558-04/SO, 64A-04/L, 65B-04/L, 65B-04I/P, 67-04I/PQ (+5 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

Ordering Code Differences
How suffixes on PIC16LC map to package, grade, and reel options.
PIC16LC uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 558-04/SO, 64A-04/L, 65B-04/L, 65B-04I/P, 67-04I/PQ, 71-04I/SO, 73A-04/SP, 74B-04I/PQ, 923-04/L, 923-04I/L.
Full MPN examples: PIC16LC558-04/SO, PIC16LC64A-04/L, PIC16LC65B-04/L, PIC16LC65B-04I/P, PIC16LC67-04I/PQ.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right PIC16LC Microcontrollers
Match the footprint first
Packages here: 44-LCC (J-Lead). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For PIC16LC, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "PIC16LC" — include the full suffix (e.g. 558-04/SO, 64A-04/L, 65B-04/L). RFQ with reel/tube preference and required date code.
