MCR03EZPFX33R0 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX33R0 is a 33 Ohm ±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 MCR03EZPFX33R0 is determined by strict equivalence across the following parameters: resistance value (33 Ohms), 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 grouped into two categories:

Direct Substitutes (Automotive AEC-Q200 Rated): CRCW060333R0FKEA, CRCW060333R0FKEB, and ERJ-3EKF33R0V meet all electrical and mechanical specifications with automotive qualification. RMCF0603FT33R0 also qualifies as a direct substitute with identical electrical parameters and AEC-Q200 rating.

Similar Substitutes (Moisture Resistant, Non-Automotive Rated): CR0603-FX-33R0ELF and RC0603FR-0733RL match all electrical specifications and physical dimensions but feature moisture-resistant construction instead of automotive AEC-Q200 qualification. These are suitable for applications where automotive qualification is not required.

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 qualification, select from active-status direct substitutes: ERJ-3EKF33R0V (Panasonic) or RMCF0603FT33R0 (Stackpole). Both maintain full compliance with automotive standards and are currently in active production with substantial inventory availability.

CRCW060333R0FKEA (Vishay Dale) is an active-status alternative with automotive AEC-Q200 rating and the highest inventory level (163,300 pcs), suitable for high-volume applications.

For non-automotive applications where AEC-Q200 qualification is not required, CR0603-FX-33R0ELF (Bourns) and RC0603FR-0733RL (YAGEO) provide equivalent electrical performance with moisture-resistant construction and active product status.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 classification consistent with the original MCR03EZPFX33R0.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-33R0ELF or RC0603FR-0733RL as direct replacements for MCR03EZPFX33R0 in automotive applications?

A: No. CR0603-FX-33R0ELF and RC0603FR-0733RL lack AEC-Q200 automotive qualification. Use these only in non-automotive applications. For automotive use, select ERJ-3EKF33R0V, RMCF0603FT33R0, or CRCW060333R0FKEA.

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

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical electrical termination count (2 terminations). Physical dimensions vary slightly within tolerance (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but all are compatible with standard 0603 PCB footprints.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Both are tape-and-reel formats suitable for automated assembly. Cut Tape & Digi-Reel® offers flexibility for smaller quantities, while Tape & Reel (TR) is optimized for high-volume production runs. Electrical and mechanical specifications are identical.

Q: Why is CRCW060333R0FKEB listed as discontinued if CRCW060333R0FKEA is active?

A: CRCW060333R0FKEB and CRCW060333R0FKEA are the same part with different packaging formats (TR vs. CT & Digi-Reel®). The TR variant is discontinued at DiGi Electronics, but the CT & Digi-Reel® variant remains in active production.

Q: Do all substitutes meet the same compliance requirements?

A: All listed parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99. Automotive-rated substitutes (ERJ-3EKF33R0V, RMCF0603FT33R0, CRCW060333R0FKEA, CRCW060333R0FKEB) carry AEC-Q200 qualification. Moisture-resistant substitutes (CR0603-FX-33R0ELF, RC0603FR-0733RL) do not have automotive qualification.
