CSR2010FT10L0 Equivalent & Substitute Parts

Part Overview

The CSR2010FT10L0 is a 10 mOhms ±1% 1W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This current sense thick film resistor operates across -55°C to 155°C and is designed for precision current measurement applications. The part is Active status and ROHS3 compliant. Substitute parts may be required due to inventory constraints, supply chain optimization, or application-specific performance requirements such as automotive qualification or alternative composition technologies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following core parameters: resistance value (10 mOhms), tolerance (±1%), power rating (1W), package type (2010 / 5025 Metric), and operating temperature range (-55°C ~ 155°C). All substitute parts meet these electrical and mechanical requirements. Secondary parameters including composition type (thick film or metal element), temperature coefficient, and specific certifications (such as AEC-Q200 for automotive applications) define performance characteristics but do not prevent substitution when primary parameters align.

The CSR2010FT10L0 has two qualified substitutes:

1. CSRN2010FK10L0 (Stackpole Electronics Inc) — Direct manufacturer alternative with identical electrical specifications
2. PMR50HZPFU10L0 (Rohm Semiconductor) — Cross-manufacturer substitute with automotive AEC-Q200 qualification

Parameter Comparison

Engineering Selection Recommendations

All three parts are Active status and ROHS3 compliant, meeting baseline regulatory requirements. Selection between CSR2010FT10L0 and CSRN2010FK10L0 depends on inventory availability and tolerance to temperature coefficient variation (±100ppm/°C versus ±250ppm/°C). The PMR50HZPFU10L0 is suitable for applications requiring automotive AEC-Q200 qualification and offers metal element composition with tighter temperature coefficient (±100ppm/°C) and lower seated height (0.019" versus 0.026" and 0.030"). Physical dimension variations across all three parts remain within 2010 package specifications and are compatible with standard PCB layouts for this footprint.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FK10L0 directly replace CSR2010FT10L0?

A: Yes. Both parts share identical resistance (10 mOhms), tolerance (±1%), power rating (1W), package (2010), and operating temperature range (-55°C ~ 155°C). The primary difference is temperature coefficient (±250ppm/°C versus ±100ppm/°C). Applications with strict temperature stability requirements should evaluate this specification.

Q: Is PMR50HZPFU10L0 compatible with non-automotive applications?

A: Yes. PMR50HZPFU10L0 meets all electrical and mechanical requirements for the 2010 package current sense resistor category. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits. The metal element composition and lower temperature coefficient may provide performance benefits in precision applications.

Q: Are there physical footprint compatibility concerns?

A: All three parts conform to 2010 (5025 Metric) package specifications. Seated heights vary (0.026", 0.030", 0.019"), but these differences are within standard PCB assembly tolerances for this package class. Verify PCB clearance requirements for your specific application if height is a constraint.

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

A: Both compositions meet the specified electrical parameters. Metal element resistors (PMR50HZPFU10L0) typically offer superior temperature stability and lower temperature coefficient. Thick film resistors (CSR2010FT10L0, CSRN2010FK10L0) are established current sense solutions. Selection depends on application precision requirements.

Q: Can these parts be used interchangeably in production?

A: Yes, provided your design and qualification process accommodate the specified parameter ranges. Document composition type, temperature coefficient, and any automotive qualification requirements in your component specification to ensure consistency across production batches.
