ERJ-MP4MF47MU Equivalent & Substitute Parts

Part Overview

The ERJ-MP4MF47MU is a 47 milliohm, ±1% tolerance, 1W chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This metal element current sense resistor is designed for automotive applications with AEC-Q200 qualification and moisture resistance. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this specific resistance value and power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-MP4MF47MU is determined by strict equivalence across the following parameters: resistance value (47 mOhms), tolerance (±1%), power rating (1W), package type (2512/6432 Metric), temperature coefficient (±75 ppm/°C), and operating temperature range compatibility. All identified substitutes maintain these core electrical specifications and the same physical package footprint, ensuring mechanical and electrical interchangeability in circuit applications.

The two substitute parts are classified as follows:

Direct Substitute (TL3AR047F): TE Connectivity part with identical electrical specifications, same package, and equivalent current sense application focus. Composition differs (metal foil vs. metal element) but maintains equivalent performance characteristics.

Similar Substitute (PE2512FKM070R047L): YAGEO part with identical electrical specifications and package. Composition is metal film. Operating temperature minimum is -55°C (versus -65°C for main part). Product status is active, providing long-term availability. Automotive AEC-Q200 qualification is maintained.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification: PE2512FKM070R047L (YAGEO) is the preferred substitute. This part maintains full automotive compliance and is currently in active production, ensuring long-term availability and supply chain stability. The operating temperature minimum of -55°C is suitable for most automotive environments; applications requiring -65°C minimum operation should evaluate circuit-level thermal management.

For applications where AEC-Q200 is not required: TL3AR047F (TE Connectivity) provides direct electrical equivalence with identical temperature range. However, this part is also obsolete; inventory availability should be confirmed before design commitment.

For new designs or long-term production: PE2512FKM070R047L is the only active product among the three options and should be the primary selection to ensure sustained component availability.

All three parts are ROHS3 compliant and carry MSL 1 rating, meeting environmental and moisture sensitivity requirements for standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can TL3AR047F replace ERJ-MP4MF47MU directly in existing designs?

A: Yes. Both parts share identical electrical specifications (47 mOhms, ±1%, 1W, ±75 ppm/°C), the same 2512 package footprint, and equivalent operating temperature range (-65°C to 170°C). The difference in composition (metal foil vs. metal element) does not affect electrical performance for current sense applications. However, both parts are obsolete; inventory availability must be confirmed.

Q: What is the key difference between PE2512FKM070R047L and the original part?

A: PE2512FKM070R047L differs in two aspects: (1) composition is metal film instead of metal element, and (2) operating temperature minimum is -55°C instead of -65°C. All other electrical parameters are identical. The part is currently active in production, providing supply continuity. For applications operating below -55°C, the original specification must be maintained or circuit design must be re-evaluated.

Q: Are all three parts suitable for automotive applications?

A: ERJ-MP4MF47MU and PE2512FKM070R047L both carry AEC-Q200 qualification for automotive use. TL3AR047F does not have AEC-Q200 rating; its use in automotive applications requires design review and customer approval.

Q: What is the physical footprint compatibility?

A: All three parts use the 2512 (6432 Metric) package with identical land pattern dimensions (0.252" L × 0.126" W / 6.40mm × 3.20mm). Height differences are minimal (0.035" for ERJ-MP4MF47MU and PE2512FKM070R047L; 0.024" for TL3AR047F) and do not affect PCB assembly or clearance in standard designs.

Q: Which part should be selected for new production?

A: PE2512FKM070R047L (YAGEO) is the recommended choice for new designs. It is the only active product, maintains automotive AEC-Q200 compliance, and ensures long-term supply availability. The -55°C to 170°C operating range covers standard industrial and automotive temperature requirements.
