Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSRF2512FK150L is determined by strict equivalence in the following parameters:

• Resistance value: 150 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package: 2512 (6432 Metric)
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The CSR2512FKR150 qualifies as a manufacturer-recommended substitute. While composition differs (thick film versus metal foil), both parts meet the specified electrical parameters and package requirements for current sense applications. The substitute maintains the same resistance, tolerance, power rating, and package footprint.

Parameter Comparison

Engineering Selection Recommendations

The CSR2512FKR150 is the manufacturer-recommended substitute for the obsolete CSRF2512FK150L. Both parts are ROHS3 compliant and maintain identical resistance, tolerance, power rating, and package specifications. The substitute is currently in active production status, ensuring availability for new designs and replacement applications.

Selection of the CSR2512FKR150 is appropriate for current sense applications requiring 150 mOhms ±1% at 2W in the 2512 package. The substitute maintains full compatibility with existing PCB layouts and footprints. The difference in temperature coefficient (±200ppm/°C versus ±50ppm/°C) and maximum operating temperature (155°C versus 170°C) should be evaluated against specific circuit requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the CSR2512FKR150 be used as a direct replacement for the CSRF2512FK150L?

A: Yes. Both parts share identical resistance (150 mOhms), tolerance (±1%), power rating (2W), and package (2512). The CSR2512FKR150 is the manufacturer-recommended substitute and maintains full PCB footprint compatibility.

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

A: The CSRF2512FK150L uses metal foil construction, while the CSR2512FKR150 uses thick film construction. Both compositions achieve the specified ±1% tolerance and 2W power rating. The metal foil composition of the original part provides a lower temperature coefficient (±50ppm/°C versus ±200ppm/°C).

Q: Are there operating temperature limitations with the substitute?

A: The CSR2512FKR150 operates from -55°C to 155°C, compared to the original part's -55°C to 170°C range. Applications requiring operation above 155°C should not use the substitute without circuit re-evaluation.

Q: Is the CSR2512FKR150 available in the same packaging options?

A: The CSR2512FKR150 is supplied in Tape & Reel (TR) packaging. Both parts use the 2512 (6432 Metric) package with identical footprint dimensions for PCB placement.

Q: Do both parts meet automotive standards?

A: The CSRF2512FK150L carries AEC-Q200 automotive qualification. The CSR2512FKR150 is specified for current sense applications but does not list AEC-Q200 qualification in the provided data. Applications requiring automotive certification should confirm compliance requirements.
