MCR03EZPFX20R5 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX20R5 is a 20.5 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 eligibility for the MCR03EZPFX20R5 is determined by strict equivalence across the following critical parameters:

Resistance value: 20.5 Ohms
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
Termination count: 2
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Direct substitutes from Rohm Semiconductor (MCR03ERTF20R5) and cross-manufacturer alternatives (Vishay Dale CRCW060320R5FKEA, Panasonic ERJ-3EKF20R5V, Stackpole RMCF0603FT20R5) maintain full parameter equivalence. The YAGEO RC0603FR-0720R5L is classified as a similar substitute with identical electrical specifications but differs in specific feature designation (Moisture Resistant vs. Automotive AEC-Q200).

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from CRCW060320R5FKEA (Vishay Dale), ERJ-3EKF20R5V (Panasonic), or RMCF0603FT20R5 (Stackpole). All three maintain active product status with full automotive certification and ROHS3 compliance.

The MCR03ERTF20R5 (Rohm Semiconductor) provides direct manufacturer continuity but is discontinued. The RC0603FR-0720R5L (YAGEO) is actively available with identical electrical specifications and ROHS3 compliance but lacks AEC-Q200 certification, making it suitable only for non-automotive applications.

For new designs or production requiring long-term availability, ERJ-3EKF20R5V offers the highest inventory level (129,441 pieces) with active status and full automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF20R5 directly replace MCR03EZPFX20R5?

A: Yes. Both are Rohm Semiconductor 20.5 Ohm ±1% 0.1W 0603 thick film resistors with identical electrical specifications, temperature coefficient, and operating range. The primary difference is packaging format (MCR03ERTF20R5 is available in Cut Tape and Digi-Reel, while MCR03EZPFX20R5 was the original package variant). Both are now discontinued at DiGi Electronics.

Q: Which substitute is best for automotive applications?

A: CRCW060320R5FKEA, ERJ-3EKF20R5V, and RMCF0603FT20R5 all carry AEC-Q200 certification. ERJ-3EKF20R5V is recommended for new production due to active status and highest available inventory.

Q: Is RC0603FR-0720R5L suitable as a replacement?

A: RC0603FR-0720R5L matches all electrical parameters and is actively available. However, it lacks AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not required.

Q: Are there physical dimension differences between substitutes?

A: Minor variations exist. CRCW060320R5FKEA measures 0.061" L × 0.033" W with 0.020" max height. MCR03EZPFX20R5, ERJ-3EKF20R5V, and RC0603FR-0720R5L measure 0.063" L × 0.031" W with 0.022" max height. RMCF0603FT20R5 measures 0.061" L × 0.031" W with 0.022" max height. All fit standard 0603 footprints.

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes. All listed parts have MSL 1 (Unlimited) moisture sensitivity, indicating no special moisture handling requirements.

Q: What is the difference between "Direct" and "Similar" substitute classifications?

A: Direct substitutes maintain full electrical and mechanical equivalence including automotive certification where applicable. The RC0603FR-0720R5L is classified as similar because it lacks AEC-Q200 certification despite matching all electrical specifications.
