ERJ-MP2MF15MU Equivalent & Substitute Parts

Part Overview

The ERJ-MP2MF15MU is a 15 mOhms ±1% 1W chip resistor in 1206 (3216 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 requiring this specific resistance value and power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-MP2MF15MU is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 15 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 1206 (3216 Metric)
• Composition: Metal Element
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Two substitute parts meet these criteria: CSNL1206FT15L0 (Stackpole Electronics Inc) and WSLP1206R0150FEA (Vishay Dale). Both maintain identical electrical specifications and package dimensions, ensuring direct functional compatibility in current sense applications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, WSLP1206R0150FEA (Vishay Dale) is the direct equivalent, maintaining identical temperature coefficient (±75ppm/°C), operating temperature range (-65°C ~ 170°C), and automotive certification. This part also includes anti-sulfur and pulse-withstanding features.

For non-automotive applications or where AEC-Q200 is not mandated, CSNL1206FT15L0 (Stackpole Electronics Inc) provides functional equivalence with improved temperature coefficient performance (±50ppm/°C), though with a slightly reduced lower operating temperature limit (-55°C vs. -65°C). Both substitute parts are in active production status, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can CSNL1206FT15L0 replace ERJ-MP2MF15MU in automotive applications?

A: CSNL1206FT15L0 meets all electrical and mechanical substitution criteria (15 mOhms ±1%, 1W, 1206 package). However, it lacks AEC-Q200 automotive certification. Use only in non-automotive circuits or where automotive qualification is not required.

Q: What is the difference between the two substitute parts?

A: Both CSNL1206FT15L0 and WSLP1206R0150FEA are electrically and mechanically equivalent. WSLP1206R0150FEA includes AEC-Q200 automotive rating, anti-sulfur coating, and pulse-withstanding capability. CSNL1206FT15L0 offers a superior temperature coefficient (±50ppm/°C vs. ±75ppm/°C).

Q: Are there packaging differences between the main part and substitutes?

A: All three parts use 1206 (3216 Metric) packaging. Dimensional variations are minimal: the original ERJ-MP2MF15MU measures 0.125" L x 0.063" W, while substitutes measure 0.126" L x 0.063" W. Height specifications are equivalent (0.035" maximum). These differences are within standard PCB design tolerances.

Q: Which substitute should I choose for new designs?

A: For automotive applications, select WSLP1206R0150FEA to maintain AEC-Q200 compliance. For general-purpose current sensing, either substitute is acceptable based on availability and cost considerations.

Q: Are all three parts RoHS compliant?

A: Yes. ERJ-MP2MF15MU, CSNL1206FT15L0, and WSLP1206R0150FEA are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
