Substitute Part Grouping Explanation
Substitution for the MCR03EZPFX5761 is determined by strict equivalence across the following parameters:
- Resistance value: 5.76 kOhms
- Tolerance: ±1%
- Power rating: 0.1W (1/10W)
- Package: 0603 (1608 Metric)
- Composition: Thick Film
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C ~ 155°C
- RoHS3 compliance
- MSL rating: 1 (Unlimited)
Substitute parts are classified into two categories:
Direct Substitutes maintain full automotive AEC-Q200 certification and identical electrical specifications.
Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 rating. These are suitable for applications where automotive qualification is not mandatory.

Engineering Selection Recommendations
For automotive applications requiring AEC-Q200 certification:
Select from the direct substitutes: CRCW06035K76FKEA (Vishay Dale), ERJ-3EKF5761V (Panasonic Electronic Components), or RMCF0603FT5K76 (Stackpole Electronics Inc). All three maintain active product status and full compliance with automotive qualification standards. CRCW06035K76FKEA offers the highest inventory availability at 38,015 pieces. ERJ-3EKF5761V provides the largest stock at 104,367 pieces. RMCF0603FT5K76 maintains 145,971 pieces in inventory.
For non-automotive applications:
CR0603-FX-5761ELF (Bourns Inc.) and RC0603FR-075K76L (YAGEO) are suitable alternatives. Both meet all electrical and mechanical specifications with moisture-resistant construction. RC0603FR-075K76L offers superior inventory availability at 280,519 pieces.
All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and identical electrical performance within the specified tolerance and temperature range.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-5761ELF or RC0603FR-075K76L in place of MCR03EZPFX5761 in automotive applications?
A: No. CR0603-FX-5761ELF and RC0603FR-075K76L lack AEC-Q200 automotive certification. Use only CRCW06035K76FKEA, ERJ-3EKF5761V, or RMCF0603FT5K76 for automotive applications requiring AEC-Q200 compliance.
Q: Are all substitute parts mechanically compatible with the original MCR03EZPFX5761?
A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions. Minor variations in length and height (within 0.002" to 0.004") do not affect PCB assembly or functionality.
Q: What is the difference between direct substitutes and similar substitutes?
A: Direct substitutes (CRCW06035K76FKEA, ERJ-3EKF5761V, RMCF0603FT5K76) maintain AEC-Q200 automotive certification. Similar substitutes (CR0603-FX-5761ELF, RC0603FR-075K76L) feature moisture-resistant construction but lack automotive qualification. Selection depends on application requirements.
Q: Do all substitute parts have the same temperature coefficient?
A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, ensuring equivalent thermal performance.
Q: Which substitute offers the best inventory availability?
A: RC0603FR-075K76L (YAGEO) provides the highest stock at 280,519 pieces. For automotive-qualified parts, RMCF0603FT5K76 (Stackpole Electronics Inc) offers 145,971 pieces.
