MCR03EZPFX1333 Equivalent & Substitute Parts
Part Overview
The MCR03EZPFX1333 is a 133 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain identical electrical and mechanical specifications for seamless integration into existing designs.

Substitute Part Grouping Explanation
Substitute parts for the MCR03EZPFX1333 are qualified based on strict equivalence across the following critical parameters:
- Resistance value: 133 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 to 155°C
- RoHS3 compliance
- MSL rating: 1 (Unlimited)
Substitute parts are categorized into two groups: Direct equivalents maintain full AEC-Q200 automotive qualification; similar substitutes meet all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 certification.

Engineering Selection Recommendations
For applications requiring strict automotive AEC-Q200 compliance, direct equivalent substitutes are CRCW0603133KFKEA (Vishay Dale), ERJ-3EKF1333V (Panasonic Electronic Components), and RMCF0603FT133K (Stackpole Electronics Inc). All three maintain active product status with full AEC-Q200 automotive qualification and ROHS3 compliance.
For non-automotive applications or designs where moisture-resistant construction is acceptable, similar substitutes CR0603-FX-1333ELF (Bourns Inc.), RC0603FR-07133KL (YAGEO), and RC1608F1333CS (Samsung Electro-Mechanics) provide equivalent electrical performance and mechanical compatibility with active product availability.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part rated for moisture resistance instead of AEC-Q200 in an automotive application?
A: No. AEC-Q200 certification and moisture-resistant construction are distinct qualifications. Automotive applications requiring AEC-Q200 compliance must use direct equivalents: CRCW0603133KFKEA, ERJ-3EKF1333V, or RMCF0603FT133K.
Q: Are all substitute parts physically compatible with the original MCR03EZPFX1333 footprint?
A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions within the specified range. PCB layout modifications are not required.
Q: What is the difference between the direct equivalents and similar substitutes?
A: Direct equivalents (CRCW0603133KFKEA, ERJ-3EKF1333V, RMCF0603FT133K) carry AEC-Q200 automotive certification. Similar substitutes (CR0603-FX-1333ELF, RC0603FR-07133KL, RC1608F1333CS) feature moisture-resistant construction but lack automotive qualification. Electrical specifications and package dimensions are identical across all substitutes.
Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?
A: No. Packaging format affects only handling and assembly logistics. RC1608F1333CS is supplied in Cut Tape format while other substitutes use Tape & Reel; electrical and mechanical performance remain identical.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed carry ROHS3 compliance and MSL rating of 1 (Unlimited), matching the original MCR03EZPFX1333 specifications.
