Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FTR250 is determined by the following critical parameters:

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

Substitute parts must maintain identical electrical specifications (resistance, tolerance, power) and mechanical compatibility (package, dimensions, terminations). Temperature coefficient variations and minor dimensional differences within the 2010 package class are permissible when all primary electrical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

CSR2010FKR250 is a direct equivalent to CSR2010FTR250. Both parts share identical electrical specifications, temperature coefficient, and mechanical dimensions. Both maintain Active product status and ROHS3 compliance. Selection between these two parts is based on inventory availability and supplier preference.

CSRN2010FKR250 is a functional substitute with the following considerations: it maintains identical resistance, tolerance, power rating, and package class. The temperature coefficient is ±250ppm/°C compared to ±100ppm/°C in the primary part, resulting in reduced temperature stability. Physical dimensions vary slightly (width 2.45mm vs 2.54mm, height 0.75mm vs 0.65mm). This part remains ROHS3 compliant and Active status. Use CSRN2010FKR250 only when the higher temperature coefficient and dimensional variance are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can CSR2010FKR250 be used as a direct replacement for CSR2010FTR250?

A: Yes. CSR2010FKR250 is electrically and mechanically equivalent. Both parts have identical resistance (250 mOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), and package dimensions (2010 / 5025 Metric). No design changes are required.

Q: What are the differences between CSR2010FTR250 and CSRN2010FKR250?

A: The primary differences are temperature coefficient (±100ppm/°C vs ±250ppm/°C) and physical dimensions. CSRN2010FKR250 has a width of 2.45mm versus 2.54mm and a maximum seated height of 0.75mm versus 0.65mm. All electrical specifications remain identical. Verify PCB layout compatibility before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CSR2010FKR250 and CSRN2010FKR250 are both ROHS3 compliant, matching the compliance status of CSR2010FTR250.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can CSRN2010FKR250 be used in high-precision temperature-dependent applications?

A: CSRN2010FKR250 has a temperature coefficient of ±250ppm/°C, which is 2.5 times higher than CSR2010FTR250 (±100ppm/°C). Applications requiring tight temperature stability should use CSR2010FTR250 or CSR2010FKR250.
