MC79L Overview

What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).

MC79L is a onsemi order-code family — not a single orderable MPN. This page lists 17 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.

Across listed variants, watch these parameters: packages: TO-226-3, TO-92-3 Long Body (Formed Leads), TO-226-3, TO-92-3 Long Body.

Suffix examples in this family: 15ACPREG, 24ACPG, 05ABDR2G, 05ACDR2G, 05ACPG, 05ACPRPG, 12ABPG, 12ABPRAG. 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.

Columns that actually vary on this page: Package Type. If two rows match on MPN prefix but differ there, they are not interchangeable for production.

Example MPNs: MC79L15ACPREG, MC79L24ACPG, MC79L05ABDR2G, MC79L05ACDR2G, MC79L05ACPG, MC79L05ACPRPG.

Ordering Code Differences

How suffixes on MC79L map to package, grade, and reel options.

MC79L 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: 15ACPREG, 24ACPG, 05ABDR2G, 05ACDR2G, 05ACPG, 05ACPRPG, 12ABPG, 12ABPRAG, 12ACDR2G, 12ACLPE3 (+7 more).

What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.

Full MPN examples: MC79L15ACPREG, MC79L24ACPG, MC79L05ABDR2G, MC79L05ACDR2G, MC79L05ACPG.

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 MC79L Integrated Circuits (ICs)

📦

Match the footprint first

Packages here: TO-226-3, TO-92-3 Long Body (Formed Leads), TO-226-3, TO-92-3 Long Body. Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For MC79L, 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 "MC79L" — include the full suffix (e.g. 15ACPREG, 24ACPG, 05ABDR2G). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the MC79L product family.

Is MC79L a single part I can order, or a family prefix?

MC79L is a base / family code from onsemi. You order a full MPN such as MC79L15ACPREG, MC79L24ACPG, MC79L05ABDR2G. The variant table lists 17 orderable lines with different suffixes.

What do the suffix letters on MC79L part numbers mean?

Listed suffix fragments include: 15ACPREG, 24ACPG, 05ABDR2G, 05ACDR2G, 05ACPG, 05ACPRPG. Typically they encode package (TO-226-3, TO-92-3 Long Body (Formed Leads), TO-226-3, TO-92-3 Long Body), temperature grade, and tape/reel option. Always decode on the onsemi datasheet ordering guide — do not guess from pattern alone.

Which specs actually differ between MC79L variants here?

On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.

Can I swap between TO-226-3, TO-92-3 Long Body (Formed Leads), TO-226-3, TO-92-3 Long Body packages in the same MC79L family?

Only after footprint and thermal review. Packages listed here (TO-226-3, TO-92-3 Long Body (Formed Leads), TO-226-3, TO-92-3 Long Body) use different land patterns and often different thermal resistance. Layout swaps need a new paste stencil at minimum, not just a BOM edit.

What is the lifecycle status of MC79L variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on MC79L?

Full manufacturer MPN (not just MC79L), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
