Bourns SRP6540
SRP6540 variants from Bourns
SRP6540 Overview
What changes between part numbers, and what to check before you lock the BOM — Passive Components.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 9 distinct suffix patternsExamples: 1R0M, 1R5M, 270M, 2R2M, 390M (+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

How to Choose the Right SRP6540 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 SRP6540, 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 "SRP6540" — include the full suffix (e.g. 1R0M, 1R5M, 270M). RFQ with reel/tube preference and required date code.
