Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRF2512FT33L0 is determined by strict alignment of the following parameters:

• Resistance value: 33 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package designation: 2512 (6432 Metric)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 170°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The PE2512FKE7W0R033L from YAGEO meets all substitution criteria. While composition differs (metal film versus metal foil), both materials satisfy the specified electrical and thermal performance requirements within the defined parameter envelope.

Parameter Comparison

Engineering Selection Recommendations
