Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSRF2512FK3L00 is determined by strict equivalence across the following parameters:

• Resistance value: 3 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package type: 2512 (6432 Metric)
• Composition: Metal Foil
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 170°C
• Automotive qualification: AEC-Q200
• Compliance standards: ROHS3, REACH Unaffected

The CSRF2512FT3L00 meets all these parameters and is manufactured by the same supplier, Stackpole Electronics Inc. The primary difference is packaging format and product status.
