Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206JTR560 is determined by the following critical parameters:

• Resistance Value: Must be 560 mOhms
• Package Type: Must be 1206 (3216 Metric)
• Power Rating: Must be 0.5W minimum
• Composition: Thick film construction
• Operating Temperature Range: Must cover -55°C to 155°C
• Compliance: ROHS3 compliance required

The RCWE1206R560FKEA qualifies as a direct substitute. While it features improved tolerance (±1% versus ±5%), identical resistance, package, power rating, and operating temperature range, it maintains all mandatory electrical and mechanical compatibility parameters. The substitute introduces automotive AEC-Q200 qualification and moisture resistance as additional features without compromising the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

The RCWE1206R560FKEA serves as a qualified substitute for the CSR1206JTR560 in applications where component availability or enhanced specifications are required. Both parts maintain identical electrical performance in the 560 mOhms resistance class and are rated for equivalent power dissipation and temperature operation.

The substitute part offers tighter tolerance (±1% versus ±5%), which may improve circuit accuracy in precision current sensing applications. The automotive AEC-Q200 qualification of the RCWE1206R560FKEA extends applicability to automotive environments, though this does not restrict its use in non-automotive applications.

Physical dimensions differ slightly within acceptable PCB layout tolerances. The substitute measures 0.122" x 0.063" with 0.028" maximum seated height compared to the main part's 0.120" x 0.061" with 0.026" maximum seated height. Both maintain 1206 package classification and are compatible with standard surface mount assembly processes.

Both parts carry ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring equivalent environmental and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can the RCWE1206R560FKEA replace the CSR1206JTR560 in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package type, and operating temperature range. The substitute's improved tolerance and automotive qualification do not create incompatibility with non-automotive applications.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance defines the acceptable resistance variation from the nominal 560 mOhms value. The ±1% tolerance of the substitute provides tighter control, resulting in more consistent current sensing measurements. Applications requiring high measurement accuracy benefit from this specification.

Q: Are the physical dimension differences between these parts critical?

A: The dimensional variations (0.120" versus 0.122" length, 0.061" versus 0.063" width, 0.026" versus 0.028" height) fall within standard 1206 package tolerances and do not affect PCB footprint compatibility or assembly processes.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard for discrete semiconductors. This qualification indicates the substitute part meets automotive reliability and performance requirements. Non-automotive applications are not restricted by this certification.

Q: Are both parts suitable for current sensing applications?

A: Yes. Both the CSR1206JTR560 and RCWE1206R560FKEA are specified as current sense resistors and perform this function identically within their respective tolerance specifications.

Q: Do packaging and moisture sensitivity differ between these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent handling and storage requirements.
