ERJ-MP2MF9M0U Equivalent & Substitute Parts

Part Overview

The ERJ-MP2MF9M0U is a 9 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 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 eligibility for the ERJ-MP2MF9M0U is determined by strict equivalence across the following parameters: resistance value (9 mOhms), tolerance (±1%), power rating (1W), package type (1206), and RoHS3 compliance. Both substitute parts meet these core electrical and mechanical requirements.

The substitute parts are grouped as follows:

Direct Substitute: CSNL1206FT9L00 (Stackpole Electronics Inc) matches all critical parameters with identical resistance, tolerance, power rating, and package specification. This part maintains current production status and full RoHS3 compliance.

Similar Substitute: CSRF1206FT9L00 (Stackpole Electronics Inc) provides equivalent electrical performance with the same resistance, tolerance, power rating, and package. This part includes automotive AEC-Q200 qualification matching the original part's automotive rating, though it uses metal foil composition instead of metal element and has a higher temperature coefficient specification.

Parameter Comparison

Engineering Selection Recommendations

CSNL1206FT9L00 is the primary substitute for non-automotive applications. This part maintains active production status, identical electrical specifications, and full RoHS3 compliance. The lower temperature coefficient (±50ppm/°C) provides improved stability across the operating range compared to the original part.

CSRF1206FT9L00 is the appropriate substitute for automotive applications requiring AEC-Q200 qualification. This part preserves the automotive rating of the original ERJ-MP2MF9M0U while maintaining all critical electrical parameters. The metal foil composition and higher temperature coefficient (±100ppm/°C) represent the primary technical differences from the original specification.

Both substitutes are in active production with confirmed inventory availability, ensuring supply chain continuity for applications currently using the obsolete ERJ-MP2MF9M0U.

Frequently Asked Questions (FAQ)

Q: Can CSNL1206FT9L00 be used in automotive applications? A: CSNL1206FT9L00 lacks AEC-Q200 automotive qualification. For automotive applications, CSRF1206FT9L00 is the appropriate substitute as it maintains AEC-Q200 certification.

Q: What is the difference between metal element and metal foil composition? A: Both compositions are suitable for current sense applications. The primary difference is reflected in the temperature coefficient specification: metal element (±75ppm/°C original, ±50ppm/°C CSNL) versus metal foil (±100ppm/°C CSRF). Selection depends on temperature stability requirements for the specific application.

Q: Are the physical dimensions interchangeable? A: All three parts use the 1206 (3216 Metric) package. Minor dimensional variations exist within standard tolerances (length 3.10-3.20mm, width 1.55-1.60mm, height 0.85-0.90mm), but all parts are mechanically compatible for standard PCB footprints designed for 1206 packages.

Q: What is the operating temperature range difference? A: The original ERJ-MP2MF9M0U operates from -65°C to 170°C. Both substitutes operate from -55°C to 170°C. Applications requiring operation below -55°C cannot use these substitutes.

Q: Are both substitutes RoHS3 compliant? A: Yes, both CSNL1206FT9L00 and CSRF1206FT9L00 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's compliance status.
