Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRF2512FT25L0 is determined by the following critical parameters:

Electrical specifications must match exactly: 25 mOhms resistance value, ±1% tolerance, and 2W power rating. Temperature coefficient of ±50ppm/°C and operating temperature range of -55°C to 170°C must be maintained. The package designation must be 2512 (6432 Metric) to ensure mechanical and thermal compatibility with existing PCB layouts and thermal management designs.

Automotive compliance is mandatory: AEC-Q200 qualification is required for applications where the main part is specified. Environmental and regulatory compliance must be equivalent: ROHS3 compliance and MSL 1 rating must be present in substitute parts.

The PE2512FKE7W0R025L from YAGEO meets all substitution criteria. While the composition differs (metal film versus metal foil), the electrical performance parameters, package dimensions, automotive ratings, and compliance certifications are equivalent and functionally interchangeable for current sense applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRF2512FT25L0 and PE2512FKE7W0R025L are active production parts with equivalent electrical and mechanical specifications for 25 mOhms current sense applications. Selection between these parts should be based on availability, lead time, and supply chain requirements rather than technical performance differences.

The CSRF2512FT25L0 (Stackpole) features metal foil composition with 1003 units in stock. The PE2512FKE7W0R025L (YAGEO) features metal film composition with 13447 units in stock. Both parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. Dimensional variations are within standard manufacturing tolerances for the 2512 package class.

Frequently Asked Questions (FAQ)

Q: Can PE2512FKE7W0R025L replace CSRF2512FT25L0 in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification standards and maintain identical electrical specifications (25 mOhms ±1%, 2W, ±50ppm/°C). The 2512 package designation ensures mechanical compatibility with existing PCB layouts.

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

A: Composition differences are provided in the part specifications. Both compositions deliver the specified electrical performance parameters for this application. Selection should be based on availability and supply chain factors.

Q: Are the dimensional differences between these parts significant?

A: Dimensional variations (0.254" vs 0.250" length, 0.128" vs 0.125" width, 0.037" vs 0.035" height) are within standard manufacturing tolerances for 2512 package resistors. Both parts are mechanically compatible with standard 2512 PCB footprints.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both CSRF2512FT25L0 and PE2512FKE7W0R025L carry MSL 1 (Unlimited) moisture sensitivity level rating, indicating equivalent environmental performance.

Q: Are both parts ROHS3 compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
