MCR03EZPFX3573 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3573 is a 357 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 alternatives from active manufacturers that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (357 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and RoHS3 compliance. Parts are grouped into two categories based on feature alignment with the original specification.

Direct Equivalents maintain full AEC-Q200 automotive qualification and identical dimensional specifications. Similar Equivalents maintain all core electrical parameters and RoHS3 compliance but feature moisture-resistant construction instead of automotive AEC-Q200 rating, with minor dimensional variations within acceptable tolerances for 0603 package footprints.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (AEC-Q200 Qualified): CRCW0603357KFKEA (Vishay Dale), ERJ-3EKF3573V (Panasonic Electronic Components), and RMCF0603FT357K (Stackpole Electronics Inc) are recommended for applications requiring automotive AEC-Q200 compliance. All three parts are in active production status with substantial inventory availability and maintain identical electrical specifications and operating temperature ranges as the original MCR03EZPFX3573.

Similar Equivalents (Moisture-Resistant): CR0603-FX-3573ELF (Bourns Inc.) and RC0603FR-07357KL (YAGEO) are suitable for non-automotive applications where moisture-resistant thick film construction is acceptable. These parts maintain all core electrical parameters and RoHS3 compliance but do not carry AEC-Q200 automotive qualification. Selection between these options should be based on application requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-3573ELF or RC0603FR-07357KL as direct replacements for MCR03EZPFX3573 in automotive applications?

A: No. CR0603-FX-3573ELF and RC0603FR-07357KL lack AEC-Q200 automotive qualification. Use CRCW0603357KFKEA, ERJ-3EKF3573V, or RMCF0603FT357K for automotive applications requiring AEC-Q200 compliance.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 0603 (1608 Metric) package. Minor dimensional variations (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm) are within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: What is the difference between direct equivalents and similar equivalents?

A: Direct equivalents (CRCW0603357KFKEA, ERJ-3EKF3573V, RMCF0603FT357K) carry AEC-Q200 automotive qualification identical to the original part. Similar equivalents (CR0603-FX-3573ELF, RC0603FR-07357KL) feature moisture-resistant construction without automotive qualification and are suitable for non-automotive applications.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original MCR03EZPFX3573 specification.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-07357KL (YAGEO) has 130,966 pieces in stock. For AEC-Q200 qualified alternatives, ERJ-3EKF3573V (Panasonic) has 39,618 pieces and CRCW0603357KFKEA (Vishay Dale) has 25,638 pieces available.
