MCR03EZPFX9310 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX9310 is a 931 Ohms ±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 MCR03EZPFX9310 is determined by strict equivalence across the following parameters:

Resistance value: 931 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
RoHS3 compliance
MSL rating: 1 (Unlimited)

Substitute parts are classified into two categories:

Direct Substitutes maintain full AEC-Q200 automotive qualification and identical electrical specifications. These parts are interchangeable without design modification.

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

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance:

Select from CRCW0603931RFKEA (Vishay Dale), ERJ-3EKF9310V (Panasonic Electronic Components), or RMCF0603FT931R (Stackpole Electronics Inc). All three parts maintain full automotive qualification and are currently in active production status with established supply availability.

For non-automotive applications:

CR0603-FX-9310ELF (Bourns Inc.), RC0603FR-07931RL (YAGEO), and RC1608F9310CS (Samsung Electro-Mechanics) provide equivalent electrical performance with moisture-resistant construction. These parts are suitable where automotive certification is not required.

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and identical electrical specifications to the original MCR03EZPFX9310.

Frequently Asked Questions (FAQ)

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

A: No. If your design requires AEC-Q200 automotive qualification, use only CRCW0603931RFKEA, ERJ-3EKF9310V, or RMCF0603FT931R. Non-automotive rated parts do not meet automotive reliability and qualification standards.

Q: Are all substitute parts pin-compatible with the MCR03EZPFX9310?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical footprint and two terminations, ensuring direct PCB compatibility without layout modification.

Q: What is the difference between AEC-Q200 rated and moisture-resistant parts?

A: AEC-Q200 rated parts undergo automotive-specific qualification testing including thermal cycling, mechanical shock, and reliability validation. Moisture-resistant parts are designed for general industrial use with enhanced moisture protection but without automotive qualification testing.

Q: Can I mix different substitute part manufacturers on the same PCB?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Mixed sourcing is acceptable from a functional standpoint, though single-source procurement is recommended for supply chain consistency.

Q: What packaging options are available?

A: Direct substitutes are available in Tape & Reel (TR) packaging. Similar substitutes offer Tape & Reel, Cut Tape (CT), and Digi-Reel options depending on manufacturer. Verify packaging availability with your supplier for production volume requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original MCR03EZPFX9310 environmental compliance profile.
