MCR03EZPFX3482 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX3482 is a 34.8 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.

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX3482 is determined by strict equivalence across the following parameters:

Resistance value: 34.8 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 to 155°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

Substitute parts are classified into two categories:

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

Similar Equivalents maintain all core electrical and mechanical parameters but differ in specific feature sets (such as moisture resistance designation rather than explicit AEC-Q200 rating). These parts are functionally equivalent for the specified parameters but may require design review for automotive-specific applications.

Engineering Selection Recommendations

For applications requiring strict AEC-Q200 automotive compliance, direct equivalents are recommended:

RMCF0603FT34K8 (Stackpole Electronics Inc): Highest inventory availability (671,931 Pcs) with active product status and full AEC-Q200 rating. Suitable for high-volume production requirements.
ERJ-3EKF3482V (Panasonic Electronic Components): Active product with substantial inventory (74,856 Pcs) and complete AEC-Q200 compliance. Established supply chain for automotive applications.
CRCW060334K8FKEA (Vishay Dale): Active product with AEC-Q200 rating and adequate inventory (26,652 Pcs). Suitable for standard automotive applications.

For applications where AEC-Q200 certification is not mandatory but moisture resistance and electrical equivalence are required:

RC0603FR-0734K8L (YAGEO): Highest inventory availability (248,393 Pcs) among similar equivalents with active product status and moisture-resistant thick film composition.
CR0603-FX-3482ELF (Bourns Inc.): Active product with moisture-resistant specification and adequate inventory (49,627 Pcs).

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and identical electrical parameters (resistance, tolerance, power rating, temperature coefficient, and operating temperature range).

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-0734K8L or CR0603-FX-3482ELF as direct replacements for MCR03EZPFX3482 in automotive applications?

A: These parts are electrically and mechanically equivalent and maintain the same operating temperature range and tolerance specifications. However, they do not carry explicit AEC-Q200 automotive certification. Use in automotive applications requires design review to confirm compliance with your specific quality and reliability requirements.

Q: What is the difference between direct equivalents and similar equivalents?

A: Direct equivalents (CRCW060334K8FKEA, ERJ-3EKF3482V, RMCF0603FT34K8) carry AEC-Q200 automotive rating identical to the original part. Similar equivalents (CR0603-FX-3482ELF, RC0603FR-0734K8L) maintain all electrical and mechanical parameters but are designated as moisture-resistant rather than explicitly AEC-Q200 rated.

Q: Are there any dimensional differences between these parts?

A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances and do not affect interchangeability.

Q: Which substitute part has the best availability?

A: RMCF0603FT34K8 (Stackpole Electronics Inc) offers the highest inventory with 671,931 Pcs in stock and maintains full AEC-Q200 compliance, making it the optimal choice for high-volume production.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes, all listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original MCR03EZPFX3482 specifications.
