ROHM MCR03ERTJ
MCR03ERTJ variants from ROHM
MCR03ERTJ 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.
- 3 distinct suffix patternsExamples: 184, 241, 475. 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 Variants
Compare 3 MCR03ERTJ part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| MCR03ERTJ184 | RES SMD 180K OHM 5% 1/10W 0603 | ROHM | Active | Compliant | In Stock | |
| MCR03ERTJ241 | RES SMD 240 OHM 5% 1/10W 0603 | ROHM | Active | Compliant | In Stock | |
| MCR03ERTJ475 | RES SMD 4.7M OHM 5% 1/10W 0603 | ROHM | Active | Compliant | In Stock |

How to Choose the Right MCR03ERTJ 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 MCR03ERTJ, 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 "MCR03ERTJ" — include the full suffix (e.g. 184, 241, 475). RFQ with reel/tube preference and required date code.
