Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSRF2512FT40L0 is determined by strict equivalence in the following parameters:

• Resistance value: 40 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package designation: 2512 (6432 Metric)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 170°C
• Automotive compliance: AEC-Q200
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The PE2512FKE7W0R04L from YAGEO meets all these electrical and mechanical requirements. While the main part uses metal foil composition and the substitute uses metal film composition, both maintain identical electrical performance specifications, dimensional compatibility within the 2512 package, and automotive qualification standards.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRF2512FT40L0 and PE2512FKE7W0R04L are active production parts with ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts is based on availability and supply chain requirements. The PE2512FKE7W0R04L offers higher inventory availability (6442 units) compared to the CSRF2512FT40L0 (867 units). Both parts maintain identical electrical specifications and operating parameters required for current sense applications in automotive environments. Dimensional variations are within standard manufacturing tolerances for the 2512 package class.

Frequently Asked Questions (FAQ)

Q: Can PE2512FKE7W0R04L replace CSRF2512FT40L0 in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, maintain identical resistance (40 mOhms ±1%), power rating (2W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 170°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between metal foil and metal film composition in these parts?

A: Composition differences are provided in the part specifications. Both compositions deliver the specified electrical performance for this resistance value and tolerance class.

Q: Are the dimensional differences between these parts significant?
