Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2010JTR400 and CSRN2010FKR400 are active production parts from Stackpole Electronics Inc with identical ROHS3 compliance and REACH unaffected status. Selection between these parts depends on tolerance requirements for the application. The CSRN2010JTR400 with ±5% tolerance is suitable for general current sensing applications where standard precision is acceptable. The CSRN2010FKR400 with ±1% tolerance provides enhanced precision for applications requiring tighter resistance value control. Both parts share identical thermal characteristics, package dimensions, and environmental ratings, ensuring direct functional interchangeability within the specified tolerance parameters.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FKR400 be used as a direct replacement for CSRN2010JTR400?

A: Yes. The CSRN2010FKR400 is a direct substitute with identical electrical and mechanical specifications. The only difference is the tolerance rating (±1% versus ±5%). This substitution is valid for any application where the tighter tolerance of the substitute part is acceptable or beneficial.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. CSRN2010JTR400 has ±5% tolerance, while CSRN2010FKR400 has ±1% tolerance. All other parameters including resistance value, power rating, package, temperature range, and physical dimensions are identical.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.097" W (5.00mm x 2.45mm) and maximum seated height of 0.030" (0.75mm). They are mechanically interchangeable on PCBs designed for this package.

Q: Do both parts have the same environmental compliance ratings?

A: Yes. Both CSRN2010JTR400 and CSRN2010FKR400 are ROHS3 compliant, REACH unaffected, and have Moisture Sensitivity Level 1 (Unlimited). They meet identical regulatory and environmental standards.

Q: What is the temperature operating range for these resistors?

A: Both parts operate across -55°C to 155°C with a temperature coefficient of ±250ppm/°C, providing stable performance across industrial and extended temperature applications.
