MCR03EZPFX3483 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3483 is a 348 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX3483 is determined by strict equivalence across the following parameters: resistance value (348 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.

Substitute parts are grouped into two categories:

Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW0603348KFKEA (Vishay Dale), ERJ-3EKF3483V (Panasonic Electronic Components), and RMCF0603FT348K (Stackpole Electronics Inc).

Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 rating: CR0603-FX-3483ELF (Bourns Inc.) and RC0603FR-07348KL (YAGEO).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring strict automotive AEC-Q200 compliance, select from the direct substitute group: CRCW0603348KFKEA, ERJ-3EKF3483V, or RMCF0603FT348K. All three maintain full automotive qualification and are currently in active production status with substantial inventory availability.

CRCW0603348KFKEA (Vishay Dale) offers the highest inventory level at 53,220 pieces and is available in Cut Tape and Digi-Reel packaging options.

ERJ-3EKF3483V (Panasonic Electronic Components) provides 64,956 pieces in inventory with Tape & Reel packaging.

RMCF0603FT348K (Stackpole Electronics Inc) maintains 16,178 pieces in inventory with Tape & Reel packaging.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-3483ELF (Bourns Inc.) and RC0603FR-07348KL (YAGEO) are suitable alternatives. RC0603FR-07348KL offers the largest inventory at 181,476 pieces.

All substitute parts maintain identical electrical specifications, package dimensions, and environmental compliance ratings as the original MCR03EZPFX3483.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-3483ELF or RC0603FR-07348KL as direct replacements for MCR03EZPFX3483 in automotive applications?

A: CR0603-FX-3483ELF and RC0603FR-07348KL are moisture-resistant thick film resistors without AEC-Q200 automotive certification. They are electrically and mechanically equivalent but lack the automotive qualification. Use these only in non-automotive applications or where automotive certification is not a design requirement.

Q: Are all substitute parts physically compatible with the original PCB layout?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical termination count (2 terminations) and compatible physical dimensions. Maximum seated heights range from 0.020" to 0.022", which is within standard PCB assembly tolerances.

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

A: Cut Tape (CT) packaging is suitable for small-volume manual assembly or prototyping. Tape & Reel (TR) packaging is designed for high-volume automated assembly processes. Both packaging formats contain the same component; the choice depends on production volume and assembly equipment.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance of the original MCR03EZPFX3483.

Q: Which substitute offers the best availability?

A: RC0603FR-07348KL (YAGEO) has the highest inventory at 181,476 pieces. For automotive-qualified alternatives, ERJ-3EKF3483V (Panasonic) offers 64,956 pieces in stock.
