Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRF2512FT50L0 is determined by the following critical parameters:

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

The PE2512FKE7W0R05L from YAGEO meets all electrical and mechanical requirements for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, temperature specifications, and automotive certifications. The primary composition difference (metal foil versus metal film) does not affect functional compatibility within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRF2512FT50L0 and PE2512FKE7W0R05L are active production parts with ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts is based on availability and supply chain requirements rather than electrical performance differences. The PE2512FKE7W0R05L offers higher inventory availability (4016 units) compared to the CSRF2512FT50L0 (1766 units). Both parts meet identical electrical specifications and are suitable for current sense applications in automotive environments. The minor dimensional variations fall within standard PCB layout tolerances for the 2512 package footprint.

Frequently Asked Questions (FAQ)

Q: Can PE2512FKE7W0R05L replace CSRF2512FT50L0 in automotive applications?

A: Yes. Both parts meet AEC-Q200 qualification, share identical electrical specifications (50 mOhms ±1%, 2W, ±50ppm/°C), and are rated for -55°C to 170°C operation. The metal film composition of the YAGEO part does not affect functional compatibility within these parameters.

Q: Are there PCB layout considerations when substituting these parts?

A: The parts have minor dimensional differences within the 2512 package standard. CSRF2512FT50L0 measures 6.45mm x 3.25mm with 0.95mm maximum height, while PE2512FKE7W0R05L measures 6.35mm x 3.18mm with 0.89mm maximum height. These variations are within typical PCB design tolerances for this package class.

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

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

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

A: Both compositions meet the specified electrical parameters for this application. The choice between them is determined by manufacturer design and does not affect substitution eligibility when all other specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both CSRF2512FT50L0 and PE2512FKE7W0R05L are ROHS3 compliant and REACH unaffected.
