SRF0905 Overview

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

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
5 distinct suffix patternsExamples: 100Y, 102Y, 202Y, 471Y, 501Y. Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Microcontrollers — 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 SRF0905 Microcontrollers

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For SRF0905, 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 "SRF0905" — include the full suffix (e.g. 100Y, 102Y, 202Y). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the SRF0905 product family.

Is SRF0905 a single part I can order, or a family prefix?

SRF0905 is a base / family code from Bourns. You order a full MPN such as SRF0905-100Y, SRF0905-102Y, SRF0905-202Y. The variant table lists 5 orderable lines with different suffixes.

What do the suffix letters on SRF0905 part numbers mean?

Listed suffix fragments include: 100Y, 102Y, 202Y, 471Y, 501Y. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Bourns datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of SRF0905 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 SRF0905?

Full manufacturer MPN (not just SRF0905), 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.
