Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSR0805FT56L0 is determined by the following critical parameters:

• Resistance value: 56 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Power rating: Equal to or greater than 0.25W
• RoHS compliance: ROHS3 or equivalent

The ERJ-6BWFR056V from Panasonic Electronic Components meets all substitution criteria with identical resistance, tolerance, package, and composition specifications. The substitute part provides increased power rating (0.5W versus 0.25W), which is acceptable for direct substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with ROHS3 compliance and identical moisture sensitivity ratings. The CSR0805FT56L0 is suitable for applications with 0.25W power dissipation requirements. The ERJ-6BWFR056V provides equivalent electrical performance with increased power handling capability (0.5W) and includes automotive AEC-Q200 qualification, making it suitable for applications requiring higher thermal margin or automotive-grade reliability. Selection between these parts depends on application power dissipation requirements and whether automotive qualification is necessary.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6BWFR056V replace CSR0805FT56L0 in existing designs?

A: Yes. The ERJ-6BWFR056V maintains identical resistance value, tolerance, package dimensions, and operating temperature range. The increased power rating (0.5W versus 0.25W) does not affect electrical performance in circuits designed for the original 0.25W part.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Maximum seated height differs slightly: CSR0805FT56L0 is 0.026" while ERJ-6BWFR056V is 0.030". This difference is within standard PCB assembly tolerances and does not affect board-level compatibility.

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

A: AEC-Q200 is an automotive qualification standard. The ERJ-6BWFR056V meets automotive reliability requirements, making it suitable for automotive applications. This qualification is not required for industrial or consumer applications but provides additional assurance of product quality and reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both CSR0805FT56L0 and ERJ-6BWFR056V are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic components.

Q: What is the difference in temperature coefficient specifications?

A: CSR0805FT56L0 specifies ±200ppm/°C while ERJ-6BWFR056V specifies 0/+200ppm/°C. Both fall within acceptable ranges for current sense resistor applications across the -55°C to 155°C operating temperature range.
