SRP4020TA variants from Bourns
SRP4020TA Overview
What changes between part numbers, and what to check before you lock the BOM — Passive Components.
SRP4020TA is a Bourns order-code family — not a single orderable MPN. This page lists 15 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 1.8A 243 MOHM SMD; FIXED IND 15UH 1.5A 374 MOHM SMD.
Suffix examples in this family: R22Y, 100M, 150M, 1R0M, 1R5M, 220M, 2R2M, 3R3M. 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: SRP4020TA-R22Y, SRP4020TA-100M, SRP4020TA-150M, SRP4020TA-1R0M, SRP4020TA-1R5M, SRP4020TA-220M.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 15 distinct suffix patternsExamples: R22Y, 100M, 150M, 1R0M, 1R5M (+10 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 SRP4020TA map to package, grade, and reel options.
SRP4020TA 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: R22Y, 100M, 150M, 1R0M, 1R5M, 220M, 2R2M, 3R3M, 4R7M, 5R6M (+5 more).
Full MPN examples: SRP4020TA-R22Y, SRP4020TA-100M, SRP4020TA-150M, SRP4020TA-1R0M, SRP4020TA-1R5M.
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 SRP4020TA 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 SRP4020TA, 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 "SRP4020TA" — include the full suffix (e.g. R22Y, 100M, 150M). RFQ with reel/tube preference and required date code.
