MIC49300WR Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
MIC49300WR is a Microchip Technology order-code family — not a single orderable MPN. This page lists 2 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: SPak-5 (5 leads + Tab) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C | Output Type: Adjustable | Voltage Input Max: 6.5V | Supplier Device Package: S-PAK-5 Other listed variants describe: IC REG LINEAR POS ADJ 3A SPAK-5.
Across listed variants, watch these parameters: packages: SPak-5 (5 leads + Tab).
Example MPNs: MIC49300WR-TR, MIC49300WR.
Key Features
- Footprint / package: SPak-5 (5 leads + Tab)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.
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 Variants
Compare 2 MIC49300WR part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

Ordering Code Differences
How suffixes on MIC49300WR map to package, grade, and reel options.
MIC49300WR 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: TR.
Full MPN examples: MIC49300WR-TR.
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 MIC49300WR Integrated Circuits (ICs)
Match the footprint first
Packages here: SPak-5 (5 leads + Tab). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For MIC49300WR, 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 "MIC49300WR" — include the full suffix (e.g. TR). RFQ with reel/tube preference and required date code.
