MC78L Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
MC78L is a onsemi order-code family — not a single orderable MPN. This page lists 32 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.
Package: TO-226-3, TO-92-3 Long Body (Formed Leads) | Mounting Type: Through Hole | Operating Temperature: 0°C ~ 125°C | Output Type: Fixed | Voltage Input Max: 35V | Supplier Device Package: TO-92 (TO-226) Other listed variants describe: 5V LDO Regulator, 100mA, 30V In, SOIC-8, Tape & Reel; Linear Voltage Regulator, 100 mA, 5 to 24 V, Positive Vout: 5.0 V; TJ = -40°C to +125°C, TO-92 (TO-226) 5.33mm Body Height, 2000-FNFLD.
Across listed variants, watch these parameters: packages: TO-226-3, TO-92-3 Long Body (Formed Leads).
Suffix examples in this family: 12ACPRMG, 18ACPRMG, 05ABDR2G, 05ABPRMG, 05ACDR2G, 05ACHT1G, 05ACPG, 05ACPRPG. 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: MC78L12ACPRMG, MC78L18ACPRMG, MC78L05ABDR2G, MC78L05ABPRMG, MC78L05ACDR2G, MC78L05ACHT1G.
Key Features
- Footprint / package: TO-226-3, TO-92-3 Long Body (Formed Leads)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.
- 32 distinct suffix patternsExamples: 12ACPRMG, 18ACPRMG, 05ABDR2G, 05ABPRMG, 05ACDR2G (+27 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Integrated Circuits (ICs) — 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 MC78L map to package, grade, and reel options.
MC78L 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: 12ACPRMG, 18ACPRMG, 05ABDR2G, 05ABPRMG, 05ACDR2G, 05ACHT1G, 05ACPG, 05ACPRPG, 08ABDR2G, 08ABPG (+22 more).
Full MPN examples: MC78L12ACPRMG, MC78L18ACPRMG, MC78L05ABDR2G, MC78L05ABPRMG, MC78L05ACDR2G.
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 MC78L Integrated Circuits (ICs)
Match the footprint first
Packages here: TO-226-3, TO-92-3 Long Body (Formed Leads). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For MC78L, 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 "MC78L" — include the full suffix (e.g. 12ACPRMG, 18ACPRMG, 05ABDR2G). RFQ with reel/tube preference and required date code.
