CSR1206FT22L0 Equivalent & Substitute Parts

Part Overview

The CSR1206FT22L0 is a 22 mOhms ±1% 0.5W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This current sense resistor is designed for precision low-resistance applications requiring tight tolerance and stable performance across industrial temperature ranges. The part is active in production and widely used in power management and current monitoring circuits. Substitute parts may be required due to inventory constraints, supply chain considerations, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FT22L0 is determined by the following critical parameters:

• Resistance Value: Must be 22 mOhms
• Tolerance: Must be ±1%
• Power Rating: Must be 0.5W (1/2W)
• Package Type: Must be 1206 (3216 Metric)
• Composition: Must be Thick Film
• Operating Temperature Range: Must support -55°C to 155°C
• RoHS Compliance: Must be ROHS3 Compliant

The UCR18EVHFSR022 from Rohm Semiconductor meets all these core electrical and mechanical requirements. Both parts share identical resistance, tolerance, power rating, package dimensions, and environmental compliance specifications. The substitute part maintains functional equivalence for standard current sense applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR1206FT22L0 and UCR18EVHFSR022 are active production parts with ROHS3 compliance and identical core electrical specifications. The primary differentiation is the UCR18EVHFSR022 carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. The temperature coefficient specification differs between the two parts (±100ppm/°C versus 0/+200ppm/°C), which may be relevant for applications requiring superior temperature stability. Both parts maintain the same package footprint and thermal characteristics, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the UCR18EVHFSR022 be used as a direct replacement for the CSR1206FT22L0?

A: Yes. Both parts share identical resistance (22 mOhms), tolerance (±1%), power rating (0.5W), package (1206), and operating temperature range (-55°C to 155°C). The physical dimensions and electrical performance are equivalent for standard current sense applications.

Q: What is the difference in temperature coefficient between these parts?

A: The CSR1206FT22L0 has a temperature coefficient of ±100ppm/°C, while the UCR18EVHFSR022 has 0/+200ppm/°C. Applications requiring tighter temperature stability may prefer the Stackpole part, though both remain within acceptable ranges for most industrial applications.

Q: Does the AEC-Q200 qualification on the Rohm part affect compatibility?

A: No. AEC-Q200 is an additional qualification that indicates automotive-grade reliability. It does not restrict use in non-automotive applications. The Rohm part can be used in any application where the Stackpole part is specified.

Q: Are the physical dimensions identical?

A: Both parts use the 1206 (3216 Metric) package. The Stackpole part measures 0.120" L x 0.061" W (3.05mm x 1.55mm), while the Rohm part measures 0.126" L x 0.063" W (3.20mm x 1.60mm). Both have a maximum seated height of 0.026" (0.65mm). These minor dimensional variations are within standard 1206 package tolerances and do not affect PCB compatibility.

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

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
