Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-MP3KF47MU is determined by the following critical parameters:

• Resistance value: 47 mOhms
• Tolerance: ±1%
• Package: 2010 (5025 Metric)
• Termination count: 2
• Composition compatibility: Metal Element or Metal Film
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Substitute parts must maintain identical resistance, tolerance, and package specifications. Power rating may exceed the original specification while maintaining the same package footprint and thermal characteristics. Temperature coefficient and operating temperature range variations are acceptable within the constraints of the application environment.

Parameter Comparison

Engineering Selection Recommendations

CSNL2010FT47L0 (Stackpole Electronics Inc) qualifies as a direct substitute. This part maintains identical resistance, tolerance, and package specifications while offering increased power rating (1.5W vs 0.5W). The part is active in production, ROHS3 compliant, and carries MSL rating 1. The temperature coefficient improvement (±50ppm/°C vs ±75ppm/°C) provides enhanced stability. The operating temperature minimum of -55°C is acceptable for most applications requiring the original -65°C specification.

PE2010FKM070R047L (YAGEO) functions as a compatible alternative with equivalent electrical performance. This part maintains the original 0.5W power rating, ±75ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The metal film composition differs from the original metal element construction but provides equivalent current sense functionality. The part is active in production and ROHS3 compliant with MSL rating 1.

Frequently Asked Questions (FAQ)

Q: Can CSNL2010FT47L0 replace ERJ-MP3KF47MU in all applications?

A: Yes, within the operating temperature range of -55°C to 170°C. The increased power rating (1.5W) and improved temperature coefficient (±50ppm/°C) make this part suitable for the original application envelope. Verify that your circuit does not require operation below -55°C.

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

A: Both compositions provide equivalent resistance and tolerance specifications for current sense applications. Metal film (PE2010FKM070R047L) offers improved temperature coefficient stability. Metal element (CSNL2010FT47L0) maintains the original construction type. Selection depends on application-specific thermal stability requirements.

Q: Are all substitute parts automotive qualified?

A: PE2010FKM070R047L carries AEC-Q200 qualification matching the original part. CSNL2010FT47L0 does not list AEC-Q200 qualification. For automotive applications requiring AEC-Q200 compliance, PE2010FKM070R047L is the appropriate selection.

Q: Do the substitute parts have identical package dimensions?

A: All parts use the 2010 (5025 Metric) package with compatible footprints. Dimensional variations are within standard tolerance: length 5.00-5.08mm, width 2.50-2.54mm, height 0.89-0.90mm. PCB layout compatibility is maintained across all three parts.

Q: What is the significance of MSL rating 1?

A: MSL rating 1 indicates unlimited shelf life without moisture bake requirements. All three parts carry this rating, ensuring equivalent moisture sensitivity handling and storage procedures.
