CSR1206FT47L0 Equivalent & Substitute Parts

Part Overview

The CSR1206FT47L0 is a 47 milliohm, ±1% tolerance, 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 high accuracy and thermal stability. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when original inventory is unavailable or when design requirements necessitate alternative qualified sources meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FT47L0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 47 mOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C to +155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The substitute part UCR18EVHFSR047 meets all mandatory electrical and mechanical requirements. Additional qualifications such as automotive AEC-Q200 certification represent enhanced capability and do not disqualify the part from substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR1206FT47L0 and UCR18EVHFSR047 are active production parts with ROHS3 compliance and identical moisture sensitivity ratings. The Stackpole CSR1206FT47L0 is suitable for general industrial and commercial current sense applications. The Rohm UCR18EVHFSR047 carries AEC-Q200 automotive qualification, making it appropriate for automotive and high-reliability applications where enhanced qualification documentation is required. Selection between these parts should be based on application requirements and supply chain availability. Physical dimensions show minor variations within standard PCB layout tolerances; verification of board-level fit is recommended for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can UCR18EVHFSR047 be used as a direct replacement for CSR1206FT47L0?

A: Yes. Both parts share identical electrical specifications (47 mOhms, ±1%, 0.5W), package type (1206), composition (thick film), and operating temperature range (-55°C to +155°C). Physical dimensions differ slightly but remain within standard PCB layout tolerances for 1206 packages.

Q: What is the significance of the AEC-Q200 rating on the Rohm part?

A: AEC-Q200 is an automotive qualification standard indicating enhanced reliability testing and documentation. This certification is required for automotive applications but does not affect electrical performance in non-automotive use cases.

Q: Are there differences in temperature coefficient between these parts?

A: The Stackpole CSR1206FT47L0 specifies ±100ppm/°C, while the Rohm UCR18EVHFSR047 specifies 0/+150ppm/°C. Both remain within acceptable ranges for current sense applications across the -55°C to +155°C operating window. Application-specific thermal performance requirements should guide selection.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No regulatory barriers exist to substitution between these parts.
