ERJ-MP3MF33MU Equivalent & Substitute Parts

Part Overview

The ERJ-MP3MF33MU is a 33 mOhms ±1% 1W chip resistor in 2010 (5025 Metric) package manufactured by Panasonic Electronic Components. This metal element current sense resistor is designed for automotive applications with AEC-Q200 qualification and moisture-resistant construction. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the ERJ-MP3MF33MU is determined by strict equivalence across the following parameters: resistance value (33 mOhms), tolerance (±1%), power rating (1W), package type (2010/5025 Metric), temperature coefficient (±75ppm/°C), AEC-Q200 automotive qualification, and RoHS3 compliance.

Two substitute parts meet these criteria:

PE2010FKM7W0R033L (YAGEO) — Direct equivalent with metal film composition. Maintains all electrical specifications and automotive certifications. Operating temperature range is -55°C ~ 170°C (narrower lower bound than original). Active product status.

WSL2010R0330FEA18 (Vishay Dale) — Direct equivalent with metal element composition matching the original. Maintains all electrical specifications, automotive certifications, and full operating temperature range (-65°C ~ 170°C). Includes additional pulse withstanding capability. Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified for direct replacement based on electrical parameter equivalence and AEC-Q200 automotive certification.

WSL2010R0330FEA18 (Vishay Dale) is the preferred substitute. It maintains metal element composition identical to the original, preserves the full operating temperature range (-65°C ~ 170°C), includes moisture-resistant construction, and adds pulse withstanding capability. Product is active with high inventory availability (5300 pcs).

PE2010FKM7W0R033L (YAGEO) is an acceptable alternative for applications where the lower operating temperature bound of -55°C is sufficient. Metal film composition differs from the original but meets all electrical and automotive requirements. Product is active with adequate inventory (778 pcs).

Frequently Asked Questions (FAQ)

Q: Can PE2010FKM7W0R033L replace ERJ-MP3MF33MU in all applications?

A: PE2010FKM7W0R033L is electrically equivalent and AEC-Q200 qualified. However, its operating temperature range begins at -55°C versus -65°C for the original. Applications requiring operation below -55°C require WSL2010R0330FEA18. Additionally, the original includes moisture-resistant construction; PE2010FKM7W0R033L does not specify this feature.

Q: What is the difference between metal element and metal film composition?

A: Both compositions meet the specified electrical parameters (33 mOhms ±1%, ±75ppm/°C). Metal element construction (original and WSL2010R0330FEA18) typically offers better pulse handling and moisture resistance. Metal film construction (PE2010FKM7W0R033L) provides stable performance across the specified range. Selection depends on application-specific pulse and environmental requirements.

Q: Are all substitutes in the same package?

A: Yes. All three parts use 2010 (5025 Metric) package with identical footprint dimensions and termination count. Physical board layout compatibility is maintained.

Q: What certifications apply to all substitute parts?

A: All parts are AEC-Q200 qualified for automotive use and ROHS3 compliant. All have MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Which substitute has the best availability?

A: WSL2010R0330FEA18 (Vishay Dale) has the highest inventory at 5300 pcs, followed by PE2010FKM7W0R033L (YAGEO) at 778 pcs.
