MCR03EZPFX1822 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1822 is an 18.2 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 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 MCR03EZPFX1822 is determined by strict equivalence across the following parameters:

Resistance value: 18.2 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 ~ 155°C
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1

Substitute parts are classified into two categories:

Direct Substitutes maintain full automotive AEC-Q200 certification and identical electrical specifications.

Similar Substitutes maintain all core electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 rating. These are suitable for applications where automotive qualification is not mandatory.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 certification, select from the direct substitutes: CRCW060318K2FKEA (Vishay Dale), ERJ-3EKF1822V (Panasonic Electronic Components), RMCF0603FG18K2, or RMCF0603FT18K2 (both Stackpole Electronics Inc). All four parts are in active production status with substantial inventory availability.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-1822ELF (Bourns Inc.) and RC0603FR-0718K2L (YAGEO) provide equivalent electrical performance with moisture-resistant construction and active product status.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications to the original MCR03EZPFX1822.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part in an automotive application originally designed for MCR03EZPFX1822?

A: Direct substitutes (CRCW060318K2FKEA, ERJ-3EKF1822V, RMCF0603FG18K2, RMCF0603FT18K2) maintain AEC-Q200 automotive certification and are suitable for automotive applications. Similar substitutes (CR0603-FX-1822ELF, RC0603FR-0718K2L) are not automotive-rated and should only be used in non-automotive applications.

Q: Are there physical dimension differences between the main part and substitutes?

A: Minor dimensional variations exist within acceptable tolerances. The MCR03EZPFX1822, ERJ-3EKF1822V, CR0603-FX-1822ELF, and RC0603FR-0718K2L measure 0.063" L x 0.031" W (1.60mm x 0.80mm). The CRCW060318K2FKEA, RMCF0603FG18K2, and RMCF0603FT18K2 measure 0.061" L x 0.031" W (1.55mm x 0.80mm). All are within 0603 package specification and suitable for standard PCB footprints.

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

A: Cut Tape packaging is supplied on individual tape segments suitable for smaller production runs and manual assembly. Tape & Reel packaging is supplied on continuous reels for automated pick-and-place assembly. Both formats contain identical components; selection depends on assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance identical to the original MCR03EZPFX1822.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, making it suitable for standard warehouse and assembly environments.
