Equivalent & Substitute Parts for ERJ-MP4QF4M0U

Part Overview

The ERJ-MP4QF4M0U is a 4 mOhms ±1% 3W 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 substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-MP4QF4M0U is determined by strict equivalence across the following critical parameters:

• Resistance value: 4 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Package: 2512 (6432 Metric)
• Composition: Metal Element
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

Two substitute parts meet these criteria and are suitable for direct replacement in applications requiring the ERJ-MP4QF4M0U specifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with full RoHS3 compliance and MSL 1 rating, making them suitable replacements for the obsolete ERJ-MP4QF4M0U.

ERJ-MS4SF4M0U (Panasonic): This part maintains identical electrical specifications and temperature coefficient to the main part. It is the preferred substitute when maintaining Panasonic component standardization is required. The increased seated height of 0.053" (1.35mm) versus 0.035" (0.89mm) must be verified against PCB layout constraints.

CSM2512FT4L00 (Stackpole): This part provides equivalent electrical performance with a lower temperature coefficient of ±50ppm/°C and maintains the original seated height of 0.035" (0.90mm). The operating temperature range extends to -55°C minimum, which is acceptable for applications not requiring the -65°C lower limit of the original part.

Frequently Asked Questions (FAQ)

Q: Can ERJ-MS4SF4M0U be used as a direct replacement for ERJ-MP4QF4M0U?

A: Yes. Both parts share identical resistance, tolerance, power rating, package, and compliance specifications. The primary consideration is the increased seated height (0.053" vs 0.035"), which must be verified against PCB clearance requirements.

Q: What is the difference between ERJ-MS4SF4M0U and CSM2512FT4L00?

A: Both are electrically equivalent at 4 mOhms ±1% 3W. The ERJ-MS4SF4M0U maintains the ±75ppm/°C temperature coefficient and -65°C lower operating limit of the original part. The CSM2512FT4L00 has a ±50ppm/°C temperature coefficient and -55°C lower operating limit, with seated height matching the original specification.

Q: Are all substitute parts available in the same packaging format?

A: Both substitutes are supplied in Tape & Reel (TR) format. The original ERJ-MP4QF4M0U packaging format is not specified in the provided data.

Q: Do the substitute parts meet automotive qualification requirements?

A: The ERJ-MS4SF4M0U carries AEC-Q200 automotive qualification identical to the original part. The CSM2512FT4L00 does not list AEC-Q200 qualification in the provided specifications. For automotive applications requiring AEC-Q200 certification, ERJ-MS4SF4M0U is the appropriate substitute.

Q: What is the impact of the temperature coefficient difference?

A: The CSM2512FT4L00 has a ±50ppm/°C coefficient versus ±75ppm/°C for both the original and ERJ-MS4SF4M0U. This results in lower resistance drift across temperature extremes, which may be beneficial for precision current sensing applications.
