Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSRN2010JTR250 are qualified based on the following criteria:

Resistance value must be identical: 250 mOhms Power rating must be equal or greater: 1W minimum Package / Case must be identical: 2010 (5025 Metric) Composition must be identical: Thick Film Features must be identical: Current Sense Temperature coefficient must be identical or better: ±250ppm/°C or lower Operating temperature range must equal or exceed: -55°C ~ 155°C minimum RoHS and environmental compliance must be maintained or improved

The CSRN2010FKR250 qualifies as a direct substitute with improved tolerance specification (±1% versus ±5%), maintaining all other critical parameters.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FKR250 be used as a direct replacement for CSRN2010JTR250?

A: Yes. Both parts share identical resistance value (250 mOhms), power rating (1W), package (2010), composition (Thick Film), and operating temperature range (-55°C ~ 155°C). The substitute part features improved tolerance (±1% versus ±5%), making it suitable for applications requiring higher accuracy.

Q: Are there any mechanical compatibility concerns when substituting CSRN2010FKR250 for CSRN2010JTR250?

A: No. Both parts have identical dimensions (0.197" L x 0.097" W / 5.00mm x 2.45mm) and maximum seated height (0.030" / 0.75mm), ensuring direct PCB footprint compatibility.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both CSRN2010JTR250 and CSRN2010FKR250 are ROHS3 compliant, REACH unaffected, and have identical Moisture Sensitivity Level (MSL 1 - Unlimited), meeting equivalent environmental and regulatory requirements.

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

A: The primary difference is tolerance specification. CSRN2010JTR250 has ±5% tolerance, while CSRN2010FKR250 has ±1% tolerance. All other electrical and mechanical parameters remain identical.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.
