ERJ-MP4MF5M0U Equivalent & Substitute Parts

Part Overview

The ERJ-MP4MF5M0U is a 5 mOhms ±1% 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-resistant construction. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-MP4MF5M0U is determined by the following critical parameters:

• Resistance value: 5 mOhms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Temperature Coefficient: ±75ppm/°C
• Operating Temperature Range: -65°C ~ 170°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain these specifications. Power rating may vary based on application requirements. Composition (metal element vs. metal foil) and specific feature sets (automotive qualification, current sense capability) are secondary considerations that may differ between substitutes while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

ERJ-MS4HF5M0U (Upgrade Substitute): This Panasonic part is the preferred substitute. It maintains identical electrical specifications (5 mOhms, ±1%, ±75ppm/°C, -65°C ~ 170°C) and mechanical compatibility (2512 package, same footprint dimensions). The upgrade offers increased power rating (3W vs. 1W) and is currently in active production status. It carries ROHS3 compliance and unlimited moisture sensitivity rating. The increased seated height (0.053" vs. 0.035") must be verified for PCB clearance in space-constrained applications.

TL3AR005F (Direct Substitute): This TE Connectivity part provides electrical equivalence with identical resistance, tolerance, temperature coefficient, and operating range. It maintains the same 2512 package footprint and dimensions. The metal foil composition differs from the original metal element construction. This part is obsolete but available in inventory. The lower seated height (0.024") may offer advantages in compact designs. Automotive AEC-Q200 qualification is not specified for this part.

Frequently Asked Questions (FAQ)

Q: Can ERJ-MS4HF5M0U replace ERJ-MP4MF5M0U in all applications?

A: Yes, for electrical function. The ERJ-MS4HF5M0U maintains identical resistance (5 mOhms), tolerance (±1%), temperature coefficient (±75ppm/°C), and operating range (-65°C ~ 170°C). The 2512 package footprint is identical. The increased seated height (0.053" vs. 0.035") requires verification that PCB layout and component clearances accommodate the additional 0.018" height.

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

A: Both compositions are provided in the input data. Metal element construction (ERJ-MP4MF5M0U, ERJ-MS4HF5M0U) and metal foil construction (TL3AR005F) are distinct technologies. Selection between them depends on application-specific requirements not specified in the provided parameters.

Q: Is automotive AEC-Q200 qualification required for substitution?

A: The main part (ERJ-MP4MF5M0U) and upgrade substitute (ERJ-MS4HF5M0U) both carry AEC-Q200 qualification. The direct substitute (TL3AR005F) does not specify this qualification. For automotive applications requiring AEC-Q200 compliance, the ERJ-MS4HF5M0U is the appropriate choice.

Q: Why is product status (Active vs. Obsolete) relevant?

A: Product status indicates supply chain availability and manufacturer support. The ERJ-MS4HF5M0U is in active production, ensuring long-term availability. Both the original part (ERJ-MP4MF5M0U) and direct substitute (TL3AR005F) are obsolete, limiting future procurement options.

Q: Are there packaging differences between these parts?

A: The main part is specified as "-" packaging. The ERJ-MS4HF5M0U is supplied in Tape & Reel (TR). The TL3AR005F is supplied in Cut Tape (CT). Packaging format affects handling, storage, and assembly processes but does not impact electrical or mechanical compatibility.
