CSR1206FTR270 Equivalent & Substitute Parts

Part Overview

The CSR1206FTR270 is a 270 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 with 751 units currently in stock. Substitute parts are identified when original inventory becomes unavailable or when design requirements necessitate alternative qualified sources meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FTR270 is determined by strict equivalence across the following parameters:

• Resistance value: 270 mOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance
• MSL rating: 1 or better

The RCWE1206R270FKEA from Vishay Dale meets all electrical and mechanical requirements for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. The substitute part includes additional automotive AEC-Q200 qualification and moisture-resistant features, which do not conflict with the original specification and provide enhanced reliability margins.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR1206FTR270 and RCWE1206R270FKEA are active production parts with ROHS3 compliance and identical electrical specifications. The Stackpole CSR1206FTR270 is available in Tape & Reel packaging with 751 units in current inventory. The Vishay Dale RCWE1206R270FKEA is available in Cut Tape and Digi-Reel packaging with 47,456 units in stock and includes AEC-Q200 automotive qualification.

Selection between these parts depends on application requirements and supply chain considerations. For non-automotive applications requiring standard industrial specifications, either part is functionally equivalent. For automotive or high-reliability applications, the AEC-Q200 qualified RCWE1206R270FKEA provides additional qualification documentation. Dimensional tolerances show minor variations within acceptable PCB assembly limits for 1206 package placement.

Frequently Asked Questions (FAQ)

Q: Can RCWE1206R270FKEA replace CSR1206FTR270 in existing designs?

A: Yes. Both parts share identical electrical specifications (270 mOhms ±1%, 0.5W, ±100ppm/°C, -55°C to 155°C). Dimensional differences (0.002" length, 0.002" width, 0.002" height) are within standard PCB assembly tolerances for 1206 package placement and do not require design modification.

Q: What is the significance of AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry qualification standard. The RCWE1206R270FKEA carries this certification, indicating compliance with automotive reliability and environmental testing requirements. This qualification is not required for non-automotive applications but provides additional assurance of manufacturing consistency and reliability.

Q: Are packaging differences between Tape & Reel and Cut Tape significant?

A: Packaging format affects handling and assembly processes but does not impact electrical or mechanical performance. Tape & Reel is optimized for high-volume automated assembly. Cut Tape and Digi-Reel are suitable for lower-volume or mixed-component assembly. Selection depends on production volume and assembly equipment compatibility.

Q: Do the moisture-resistant features of the substitute part affect compatibility?

A: No. Moisture-resistant composition is a manufacturing enhancement that does not conflict with the original specification. MSL rating 1 (Unlimited) applies to both parts, indicating no moisture sensitivity concerns for either component.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No compliance barriers exist for substitution in either domestic or international applications.
