CSR2010FKR150 Equivalent & Substitute Parts

Part Overview

The CSR2010FKR150 is a 150 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 across the same package class and functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FKR150 is determined by the following critical parameters:

• Resistance value: 150 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Application feature: Current Sense
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Substitute parts must maintain identical values for resistance, tolerance, power rating, package designation, and composition. Temperature coefficient variations are permitted within the operating temperature range specification. Physical dimensions may vary within the 2010 package class tolerance. All substitutes must retain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CSR2010FKR150, CSR2010FTR150, and CSRN2010FKR150—are Active status products manufactured by Stackpole Electronics Inc and maintain ROHS3 compliance and REACH Unaffected status. Selection between these parts depends on application-specific requirements:

CSR2010FKR150 and CSR2010FTR150 are direct equivalents with identical electrical specifications and temperature coefficient performance (±100ppm/°C). These parts differ only in packaging designation (FKR vs FTR tape and reel configurations) and are interchangeable for circuit design purposes.

CSRN2010FKR150 operates with a higher temperature coefficient (±250ppm/°C) and exhibits slightly different physical dimensions (0.097" width vs 0.100", 0.030" height vs 0.026"). This part remains functionally equivalent for current sense applications but introduces greater temperature-dependent resistance variation. Physical dimension differences require verification against PCB layout constraints and assembly equipment specifications.

Frequently Asked Questions (FAQ)

Q: Can CSR2010FTR150 directly replace CSR2010FKR150 in production?

A: Yes. Both parts share identical electrical specifications (150 mOhms ±1%, 1W, ±100ppm/°C) and physical dimensions. The difference lies in tape and reel packaging configuration. Verify that your assembly equipment accepts both packaging formats.

Q: Is CSRN2010FKR150 suitable as a substitute for CSR2010FKR150?

A: CSRN2010FKR150 maintains the same resistance, tolerance, power rating, and package class. However, the temperature coefficient is ±250ppm/°C versus ±100ppm/°C for the original part. Applications requiring tight temperature stability should evaluate whether this increased coefficient affects circuit performance across the -55°C to 155°C operating range. Physical dimensions also differ slightly; confirm PCB layout compatibility.

Q: What are the key differences between these substitute parts?

A: CSR2010FKR150 and CSR2010FTR150 are electrically and mechanically identical. CSRN2010FKR150 differs in temperature coefficient (±250ppm/°C vs ±100ppm/°C) and physical dimensions (width 0.097" vs 0.100", height 0.030" vs 0.026"). All three maintain 150 mOhms ±1% resistance, 1W power rating, and 2010 package compatibility.

Q: Are all three parts ROHS3 compliant?

A: Yes. CSR2010FKR150, CSR2010FTR150, and CSRN2010FKR150 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: What should I verify before switching to a substitute part?

A: Confirm that the substitute part's temperature coefficient meets your circuit's thermal stability requirements. Verify physical dimensions against PCB layout and assembly equipment specifications. Confirm tape and reel packaging compatibility with your production line.
