Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-MP3PF5M0U is determined by the following critical parameters:

• Resistance Value & Tolerance: Exact match at 5 mOhms ±1%
• Package / Case: Identical 2010 (5025 Metric) footprint for PCB compatibility
• Composition: Metal element construction for current sense applications
• Termination Count: 2 terminations required
• Compliance: ROHS3 compliance and MSL 1 rating

The CSNL2010FT5L00 from Stackpole Electronics Inc meets these core substitution criteria. Differences in power rating (1.5W vs. 2W) and temperature coefficient (±50ppm/°C vs. ±75ppm/°C) represent design trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The CSNL2010FT5L00 is a functionally compatible substitute for the obsolete ERJ-MP3PF5M0U based on matching resistance, tolerance, package, and composition specifications. Both parts maintain ROHS3 compliance and MSL 1 ratings.

Key considerations for selection:

• Power Dissipation: The substitute part is rated at 1.5W versus the original 2W. Applications requiring the full 2W dissipation capacity must evaluate whether 1.5W is sufficient for the intended current sense function.
• Temperature Coefficient: The substitute exhibits ±50ppm/°C versus ±75ppm/°C. This represents improved temperature stability and is acceptable for most current sense applications.
• Operating Temperature Lower Limit: The substitute operates from -55°C versus -65°C. Applications requiring operation below -55°C require alternative solutions.
• Automotive Qualification: The original part carries AEC-Q200 certification. The substitute does not list this qualification; automotive applications must confirm acceptability through design review.
• Availability: The substitute is in active production with higher inventory levels, ensuring supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the CSNL2010FT5L00 be used as a direct replacement for the ERJ-MP3PF5M0U?

A: The CSNL2010FT5L00 is mechanically and electrically compatible for most applications. Both parts share identical resistance, tolerance, package, and composition. However, differences in power rating, temperature coefficient, and automotive qualification must be evaluated against specific application requirements before implementation.

Q: What is the impact of the 0.5W power rating difference?

A: The substitute part is rated at 1.5W compared to the original 2W. For current sense applications, the maximum allowable current is determined by the power rating and resistance value. Applications must calculate whether the 1.5W rating provides sufficient margin for the intended current range.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical termination count and similar physical dimensions. PCB layout compatibility is maintained.

Q: Does the substitute part meet automotive standards?

A: The CSNL2010FT5L00 does not list AEC-Q200 certification. Automotive applications must confirm acceptability through design review and qualification processes.

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

A: The substitute exhibits ±50ppm/°C versus ±75ppm/°C for the original. This represents improved temperature stability. For current sense applications, lower temperature coefficient generally improves measurement accuracy across the operating temperature range.

Q: Is the -55°C lower operating limit acceptable?

A: Applications requiring operation below -55°C cannot use the substitute part. The original part operates to -65°C. Alternative solutions must be identified for such applications.
