CR0603 Overview
What changes between part numbers, and what to check before you lock the BOM — Passive Components.
CR0603 is a Bourns order-code family — not a single orderable MPN. This page lists 56 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. Other listed variants describe: RES SMD 10M OHM 1% 1/10W 0603; RES SMD 100 OHM 1% 1/10W 0603.
Suffix examples in this family: FX-1403ELF, FX-2000ELF, FW-1005ELF, FX-1000ELF, FX-1001ELF, FX-1002ELF, FX-10R0ELF, FX-1130ELF. 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: CR0603-FX-1403ELF, CR0603-FX-2000ELF, CR0603-FW-1005ELF, CR0603-FX-1000ELF, CR0603-FX-1001ELF, CR0603-FX-1002ELF.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 56 distinct suffix patternsExamples: FX-1403ELF, FX-2000ELF, FW-1005ELF, FX-1000ELF, FX-1001ELF (+51 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 CR0603 map to package, grade, and reel options.
CR0603 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: FX-1403ELF, FX-2000ELF, FW-1005ELF, FX-1000ELF, FX-1001ELF, FX-1002ELF, FX-10R0ELF, FX-1130ELF, FX-1201ELF, FX-1211ELF (+46 more).
Full MPN examples: CR0603-FX-1403ELF, CR0603-FX-2000ELF, CR0603-FW-1005ELF, CR0603-FX-1000ELF, CR0603-FX-1001ELF.
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 CR0603 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 CR0603, 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 "CR0603" — include the full suffix (e.g. FX-1403ELF, FX-2000ELF, FW-1005ELF). RFQ with reel/tube preference and required date code.
