MCR03EZPFX9092 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX9092 is a 90.9 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 MCR03EZPFX9092 is determined by strict equivalence across the following parameters:

Resistance value: 90.9 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 AEC-Q200 automotive qualification and identical electrical specifications.

Similar Substitutes meet all core electrical and mechanical parameters but feature alternative certifications (moisture resistant instead of automotive-rated) or packaging configurations.

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications:

CRCW060390K9FKEA (Vishay Dale) is the primary recommended substitute. This part maintains full AEC-Q200 automotive qualification, is currently active in production, and has the highest inventory availability (55200 Pcs). Dimensional specifications are within acceptable tolerance of the original part.

RMCF0603FT90K9 (Stackpole Electronics Inc) is an alternative direct substitute with AEC-Q200 rating, active production status, and the largest available inventory (322112 Pcs).

ERJ-3EKF9092V (Panasonic Electronic Components) provides AEC-Q200 compliance with active status, though with lower inventory levels (5300 Pcs).

For Non-Automotive Applications:

CR0603-FX-9092ELF (Bourns Inc.) and RC0603FR-0790K9L (YAGEO) are suitable alternatives where AEC-Q200 certification is not required. Both parts are active in production with adequate inventory and meet all core electrical and mechanical specifications. These parts feature moisture-resistant construction rather than automotive qualification.

Frequently Asked Questions (FAQ)

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

A: No. If your application requires AEC-Q200 compliance, only direct substitutes with AEC-Q200 rating (CRCW060390K9FKEA, CRCW060390K9FKEB, ERJ-3EKF9092V, or RMCF0603FT90K9) are acceptable. Non-automotive rated parts do not meet automotive qualification standards.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 0603 package specification. The MCR03EZPFX9092 and ERJ-3EKF9092V share identical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm). CRCW and RMCF series parts have slightly different length specifications (0.061" L, 1.55mm) but remain within 0603 package tolerance. Height specifications range from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB assembly tolerances.

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

A: Cut Tape (CT) & Digi-Reel packaging is suitable for manual assembly and small-volume production. Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly equipment and high-volume production. Both packaging formats contain identical components; the difference is in delivery and handling format.

Q: Why is the original MCR03EZPFX9092 discontinued?

A: The part is discontinued at DiGi Electronics. Equivalent substitutes from active manufacturers provide identical electrical performance and are recommended for new designs and ongoing production.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part specifications.
