MCR03EZPFX3833 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3833 is a 383 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, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX3833 is determined by strict equivalence across the following parameters: resistance value (383 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 compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are classified into two categories:

Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW0603383KFKEA (Vishay Dale), ERJ-3EKF3833V (Panasonic Electronic Components), and RMCF0603FT383K (Stackpole Electronics Inc).

Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant composition instead of automotive AEC-Q200 rating: RC0603FR-07383KL (YAGEO) and RC1608F3833CS (Samsung Electro-Mechanics).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 compliance, select from the direct substitutes: CRCW0603383KFKEA, ERJ-3EKF3833V, or RMCF0603FT383K. All three maintain active product status and full compliance with ROHS3, REACH, and EAR99 regulations.

CRCW0603383KFKEA (Vishay Dale) offers the highest inventory availability at 22,496 pieces and is supplied in Tape & Reel packaging suitable for automated assembly.

ERJ-3EKF3833V (Panasonic Electronic Components) provides the largest inventory stock at 64,901 pieces, also in Tape & Reel format.

RMCF0603FT383K (Stackpole Electronics Inc) maintains 30,424 pieces in inventory with Tape & Reel packaging.

For non-automotive applications where AEC-Q200 qualification is not required, RC0603FR-07383KL (YAGEO) and RC1608F3833CS (Samsung Electro-Mechanics) are viable alternatives. RC0603FR-07383KL offers significantly higher inventory (272,175 pieces) and is available in Tape & Reel format. RC1608F3833CS is available in Cut Tape packaging with limited inventory (789 pieces).

Frequently Asked Questions (FAQ)

Q: Can I use a non-AEC-Q200 rated substitute in an automotive application?

A: No. If your application requires automotive qualification, use only CRCW0603383KFKEA, ERJ-3EKF3833V, or RMCF0603FT383K, which maintain AEC-Q200 certification. RC0603FR-07383KL and RC1608F3833CS lack this certification.

Q: Are all substitutes mechanically compatible with the original MCR03EZPFX3833?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical electrical specifications (383 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C). Physical dimensions vary slightly but remain within 0603 package tolerances.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is optimized for automated pick-and-place assembly and is the standard for high-volume production. Cut Tape is suitable for manual assembly or low-volume applications. RC1608F3833CS is the only substitute available in Cut Tape format.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, matching the original part's environmental compliance status.

Q: Why do some substitutes list "Moisture Resistant" instead of "Automotive AEC-Q200"?

A: Moisture resistance is a material property that protects against humidity exposure. AEC-Q200 is an automotive qualification standard that includes additional reliability testing. These are distinct certifications; moisture resistance does not replace automotive qualification.
