Substitute Part Grouping Explanation
Substitution for the MCR03EZPFX42R2 is determined by strict equivalence across the following parameters:
- Resistance value: 42.2 Ohms
- 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 categorized into two groups:
Direct Substitutes (Automotive AEC-Q200 Rated): MCR03ERTF42R2, CRCW060342R2FKEA, ERJ-3EKF42R2V, and RMCF0603FT42R2 maintain full automotive qualification and are functionally equivalent across all electrical and mechanical parameters.
Similar Substitutes (Moisture Resistant, Non-Automotive): CR0603-FX-42R2ELF and RC0603FR-0742R2L meet all electrical specifications and package requirements but feature moisture-resistant composition instead of automotive AEC-Q200 certification. These are suitable for applications where automotive qualification is not required.

Engineering Selection Recommendations
For automotive applications requiring AEC-Q200 certification, select from the direct substitute group: CRCW060342R2FKEA (Vishay Dale, active status), ERJ-3EKF42R2V (Panasonic, active status with highest inventory), or RMCF0603FT42R2 (Stackpole, active status). All three maintain full compliance with automotive qualification standards.
For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-42R2ELF (Bourns) and RC0603FR-0742R2L (YAGEO) are suitable alternatives. RC0603FR-0742R2L offers the highest inventory availability at 811,485 pieces.
All substitute parts are ROHS3 compliant with MSL rating 1 (Unlimited) and identical operating temperature ranges, ensuring direct functional equivalence within their respective qualification categories.
Frequently Asked Questions (FAQ)
Q: Can MCR03ERTF42R2 replace MCR03EZPFX42R2 in automotive applications?
A: MCR03ERTF42R2 is from the same manufacturer (Rohm Semiconductor) and shares identical electrical specifications. However, MCR03ERTF42R2 does not carry AEC-Q200 automotive certification, while the original MCR03EZPFX42R2 does. For applications requiring automotive qualification, use CRCW060342R2FKEA, ERJ-3EKF42R2V, or RMCF0603FT42R2 instead.
Q: Are there dimensional differences between substitute parts?
A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist: CRCW060342R2FKEA measures 0.061" L x 0.033" W with 0.020" max height, while MCR03EZPFX42R2, ERJ-3EKF42R2V, and others measure 0.063" L x 0.031" W with 0.022" max height. These variations remain within standard 0603 package tolerances and do not affect PCB layout compatibility.
Q: What is the difference between direct and similar substitutes?
A: Direct substitutes (MCR03ERTF42R2, CRCW060342R2FKEA, ERJ-3EKF42R2V, RMCF0603FT42R2) maintain automotive AEC-Q200 certification. Similar substitutes (CR0603-FX-42R2ELF, RC0603FR-0742R2L) feature moisture-resistant composition without automotive qualification. Selection depends on application requirements.
Q: Which substitute offers the best availability?
A: RC0603FR-0742R2L (YAGEO) has the highest inventory at 811,485 pieces. For automotive-qualified alternatives, ERJ-3EKF42R2V (Panasonic) offers 59,985 pieces in stock.
Q: Are all substitutes RoHS3 compliant?
A: Yes. All listed substitutes are ROHS3 compliant with MSL rating 1 (Unlimited), matching the original MCR03EZPFX42R2 specifications.
