Key Parameters

Substitute Part Grouping Explanation

The PE2010FKM7W0R022L from YAGEO qualifies as a direct substitute based on the following critical parameters:

• Resistance Value: Both parts specify 22 mOhms with ±1% tolerance, ensuring electrical equivalence in current sensing circuits
• Package Geometry: Both use the 2010 (5025 Metric) package with identical termination count (2), enabling direct PCB footprint compatibility
• Automotive Compliance: Both parts carry AEC-Q200 qualification, meeting automotive reliability and qualification requirements
• Temperature Coefficient: Both specify ±75ppm/°C, ensuring thermal stability characteristics remain consistent
• Moisture Sensitivity: Both are rated MSL 1 (Unlimited), indicating equivalent moisture handling during storage and assembly
• RoHS Compliance: Both are ROHS3 compliant, satisfying environmental regulatory requirements

The primary difference is power rating: the substitute part is rated at 1W versus the original 0.5W. This represents an upgrade in thermal capability and does not restrict substitution in applications designed for the original 0.5W specification.

Parameter Comparison

Engineering Selection Recommendations

The PE2010FKM7W0R022L is suitable for direct substitution in applications currently specified for the ERJ-MP3KF22MU. Both parts maintain AEC-Q200 automotive qualification and ROHS3 compliance. The substitute part is in active production status, ensuring long-term availability and supply chain continuity.

The operating temperature range of the substitute part (-55°C ~ 170°C) is narrower at the lower bound compared to the original (-65°C ~ 170°C). Applications requiring operation below -55°C must be evaluated against actual circuit requirements. The higher power rating (1W versus 0.5W) of the substitute part provides additional thermal margin and does not introduce compatibility issues in circuits designed for the lower rating.

Frequently Asked Questions (FAQ)

Q: Can the PE2010FKM7W0R022L replace the ERJ-MP3KF22MU in current sensing applications?

A: Yes. Both parts specify identical resistance (22 mOhms ±1%), temperature coefficient (±75ppm/°C), and AEC-Q200 automotive qualification. The substitute part's higher power rating (1W) is compatible with circuits designed for 0.5W operation.

Q: Are the physical dimensions identical?

A: Both parts use the 2010 (5025 Metric) package with the same height (0.035" maximum seated height). Dimensional variations are within standard manufacturing tolerances for this package class and do not affect PCB footprint compatibility.

Q: What is the difference between Metal Element and Metal Film composition?

A: The original part uses Metal Element construction while the substitute uses Metal Film. Both achieve the specified ±1% tolerance and ±75ppm/°C temperature coefficient. Metal Film composition in the substitute part contributes to the higher power rating capability.

Q: Does the lower minimum operating temperature of the substitute part affect compatibility?

A: The substitute part operates from -55°C minimum versus -65°C for the original. Applications requiring operation below -55°C must confirm that actual circuit operating conditions remain within the substitute part's specified range.

Q: Are both parts compliant with current automotive and environmental standards?

A: Yes. Both parts are AEC-Q200 qualified and ROHS3 compliant. Both carry MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent handling requirements during storage and assembly.
