RE46C Overview

What changes between part numbers, and what to check before you lock the BOM — Sensors.

Key Features

Footprint / package: 16-SOIC (0.154", 3.90mm Width)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.
19 distinct suffix patternsExamples: 100E8F, 100S8F, 104S14F, 108S8F, 108S8TF (+14 more). Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Sensors — 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 RE46C Sensors

📦

Match the footprint first

Packages here: 16-SOIC (0.154", 3.90mm Width). Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For RE46C, 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 "RE46C" — include the full suffix (e.g. 100E8F, 100S8F, 104S14F). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the RE46C product family.

Is RE46C a single part I can order, or a family prefix?

RE46C is a base / family code from Microchip Technology. You order a full MPN such as RE46C100E8F, RE46C100S8F, RE46C104S14F. The variant table lists 19 orderable lines with different suffixes.

What do the suffix letters on RE46C part numbers mean?

Listed suffix fragments include: 100E8F, 100S8F, 104S14F, 108S8F, 108S8TF, 114E8F. Typically they encode package (16-SOIC (0.154", 3.90mm Width)), temperature grade, and tape/reel option. Always decode on the Microchip Technology datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of RE46C 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 RE46C?

Full manufacturer MPN (not just RE46C), 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.

Where is the RE46C datasheet?

Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
