MC79L Overview

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

Key Features

Footprint / package: TO-226-3, TO-92-3 (TO-226AA), TO-226-3, TO-92-3 (TO-226AA) Formed LeadsLand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
11 distinct suffix patternsExamples: 12ACLPE3, 15ACLPE3, 15ACLPR, 05ACDR, 05ACDR2G (+6 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

How to Choose the Right MC79L Integrated Circuits (ICs)

📦

Match the footprint first

Packages here: TO-226-3, TO-92-3 (TO-226AA), TO-226-3, TO-92-3 (TO-226AA) 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 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. 12ACLPE3, 15ACLPE3, 15ACLPR). 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 Texas Instruments. You order a full MPN such as MC79L12ACLPE3, MC79L15ACLPE3, MC79L15ACLPR. The variant table lists 11 orderable lines with different suffixes.

What do the suffix letters on MC79L part numbers mean?

Listed suffix fragments include: 12ACLPE3, 15ACLPE3, 15ACLPR, 05ACDR, 05ACDR2G, 05ACLPE3. Typically they encode package (TO-226-3, TO-92-3 (TO-226AA), TO-226-3, TO-92-3 (TO-226AA) Formed Leads), temperature grade, and tape/reel option. Always decode on the Texas Instruments 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 (TO-226AA), TO-226-3, TO-92-3 (TO-226AA) Formed Leads packages in the same MC79L family?

Only after footprint and thermal review. Packages listed here (TO-226-3, TO-92-3 (TO-226AA), TO-226-3, TO-92-3 (TO-226AA) Formed Leads) 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.
