Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FK1R00 is determined by the following critical parameters:

• Resistance value: 1 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• RoHS compliance: ROHS3 (minimum requirement)
• Moisture sensitivity: MSL 1 (minimum requirement)

The identified substitutes meet all critical electrical and mechanical parameters. Variations in temperature coefficient and physical dimensions within supplier tolerances do not affect functional equivalence for standard current sense applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and MSL 1 rating, making them functionally equivalent for standard current sense applications in the 2010 package format.

CSRN2010FT1R00 is a direct Stackpole Electronics substitute with identical electrical specifications. The temperature coefficient of ±250ppm/°C is higher than the primary part, and physical dimensions vary slightly within supplier tolerances. This part is suitable for applications where the higher temperature coefficient is acceptable.

CRCW20101R00FKEFHP is manufactured by Vishay Dale and includes AEC-Q200 automotive qualification and pulse withstanding capability. The temperature coefficient matches the primary part at ±100ppm/°C. This part is suitable for automotive applications or systems requiring enhanced pulse withstanding performance. Physical dimensions are within standard 2010 package tolerances.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FT1R00 be used as a direct replacement for CSR2010FK1R00?

A: Yes. Both parts share identical resistance, tolerance, power rating, package, and operating temperature specifications. The temperature coefficient difference (±250ppm/°C vs ±100ppm/°C) is within acceptable variation for current sense applications unless your circuit requires the tighter coefficient specification.

Q: What is the difference between CSR2010FK1R00 and CRCW20101R00FKEFHP?

A: Both parts have identical electrical specifications (1 Ohm, ±1%, 1W, ±100ppm/°C). The CRCW20101R00FKEFHP includes AEC-Q200 automotive qualification and pulse withstanding features. Select this part for automotive applications or systems requiring enhanced transient performance.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use the 2010 (5025 Metric) package with 2 terminations. Physical dimensions vary slightly (length 5.00mm, width 2.45-2.54mm, height 0.65-0.75mm), but these variations are within standard 2010 package tolerances and do not require PCB redesign.

Q: Which part should I select for new designs?

A: Selection depends on application requirements. For standard current sense circuits, any of the three parts is acceptable. For automotive applications, select CRCW20101R00FKEFHP. For cost optimization with relaxed temperature coefficient requirements, select CSRN2010FT1R00.

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.
