SRN5040 Overview

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

SRN5040 is a Bourns order-code family — not a single orderable MPN. This page lists 9 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.

Source Manufacturer: Bourns Inc. | Source: Winsource Other listed variants describe: FIXED IND 10UH 2.1A 68 MOHM SMD; FIXED IND 15UH 1.8A 96 MOHM SMD.

Suffix examples in this family: 2R2Y, 100M, 150M, 1R5Y, 3R3M, 470M, 4R7M, 6R8M. 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.

Example MPNs: SRN5040-2R2Y, SRN5040-100M, SRN5040-150M, SRN5040-1R5Y, SRN5040-3R3M, SRN5040-470M.

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
9 distinct suffix patternsExamples: 2R2Y, 100M, 150M, 1R5Y, 3R3M (+4 more). Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Passive Components — 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 Code Differences

How suffixes on SRN5040 map to package, grade, and reel options.

SRN5040 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: 2R2Y, 100M, 150M, 1R5Y, 3R3M, 470M, 4R7M, 6R8M, 8R2M.

Full MPN examples: SRN5040-2R2Y, SRN5040-100M, SRN5040-150M, SRN5040-1R5Y, SRN5040-3R3M.

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 SRN5040 Passive Components

📦

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 SRN5040, 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 "SRN5040" — include the full suffix (e.g. 2R2Y, 100M, 150M). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the SRN5040 product family.

Is SRN5040 a single part I can order, or a family prefix?

SRN5040 is a base / family code from Bourns. You order a full MPN such as SRN5040-2R2Y, SRN5040-100M, SRN5040-150M. The variant table lists 9 orderable lines with different suffixes.

What do the suffix letters on SRN5040 part numbers mean?

Listed suffix fragments include: 2R2Y, 100M, 150M, 1R5Y, 3R3M, 470M. 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 SRN5040 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 SRN5040?

Full manufacturer MPN (not just SRN5040), 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.
