CSRN2010FTR250 Equivalent & Substitute Parts

Part Overview

The CSRN2010FTR250 is a 250 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 are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRN2010FTR250 is determined by matching the following critical parameters:

• Resistance value: 250 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Features: Current Sense
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The substitute parts CSR2010FTR250 and CSR2010FKR250 meet all these criteria. Variations in temperature coefficient (±250ppm/°C vs ±100ppm/°C) and minor dimensional differences in width and height remain within acceptable mechanical tolerances for the 2010 package footprint and do not affect functional substitution in current sense applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CSRN2010FTR250, CSR2010FTR250, and CSR2010FKR250—are Active status components from Stackpole Electronics Inc with ROHS3 compliance and MSL 1 rating. They are electrically and mechanically interchangeable for current sense applications requiring 250 mOhms ±1% at 1W in the 2010 package.

CSR2010FKR250 offers superior temperature stability with ±100ppm/°C coefficient compared to CSRN2010FTR250's ±250ppm/°C, making it suitable for applications with tighter temperature compensation requirements. CSR2010FTR250 provides an intermediate option with the same improved temperature coefficient as CSR2010FKR250.

All parts maintain compliance with REACH and EAR99 export classifications. Selection should be based on application temperature stability requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CSR2010FTR250 directly replace CSRN2010FTR250?

A: Yes. Both parts share identical electrical specifications (250 mOhms ±1%, 1W, ±1% tolerance) and package footprint (2010/5025 Metric). Minor dimensional variations in width (0.097" vs 0.100") and height (0.030" vs 0.026") remain within 2010 package mechanical tolerances and do not affect PCB assembly or thermal performance.

Q: What is the difference between CSR2010FKR250 and CSR2010FTR250?

A: Both parts are electrically identical (250 mOhms ±1%, 1W) with identical package dimensions. The primary difference is series designation (CSR vs CSRN) and potential manufacturing process variations. Both offer ±100ppm/°C temperature coefficient, superior to CSRN2010FTR250's ±250ppm/°C.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts operate across -55°C to 155°C. For applications requiring minimal resistance drift over temperature, CSR2010FTR250 and CSR2010FKR250 with ±100ppm/°C coefficient are preferred over CSRN2010FTR250 with ±250ppm/°C.

Q: Do these parts require different PCB footprints?

A: No. All three parts use the 2010 (5025 Metric) package with identical footprint specifications. Dimensional variations are within package tolerance and do not require PCB redesign.

Q: Are all parts ROHS3 compliant?

A: Yes. CSRN2010FTR250, CSR2010FTR250, and CSR2010FKR250 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
