CSR0805FT36L0 Equivalent & Substitute Parts

Part Overview

The CSR0805FT36L0 is a 36 mOhm ±1% thick film chip resistor in 0805 (2012 Metric) package rated for 0.25W (1/4W) power dissipation. Designed for current sensing applications, this component operates across -55°C to 155°C with a temperature coefficient of ±200ppm/°C. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to inventory constraints, application-specific certifications, or enhanced power rating requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR0805FT36L0 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 36 mOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Features: Current Sense capability
• Operating Temperature Range: -55°C ~ 155°C
• RoHS3 Compliance

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 0.25W
• Temperature Coefficient: Within ±200ppm/°C specification
• Physical dimensions: Within 0805 package constraints
• Certifications: May include additional automotive or industrial ratings

The ERJ-6BWFR036V qualifies as a direct substitute based on identical resistance, tolerance, package, composition, and operating temperature range. The substitute provides enhanced power rating (0.5W vs. 0.25W) and includes AEC-Q200 automotive qualification, making it suitable for applications requiring higher power dissipation or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-6BWFR036V serves as a qualified substitute for the CSR0805FT36L0 in applications where component availability or enhanced specifications are required. Both parts maintain Active product status and full RoHS3 compliance. The substitute provides doubled power dissipation capacity (0.5W vs. 0.25W) while preserving all critical electrical parameters including resistance value, tolerance, and operating temperature range.

The ERJ-6BWFR036V includes AEC-Q200 automotive qualification, making it suitable for automotive and industrial applications requiring enhanced reliability standards. The maximum seated height difference (0.030" vs. 0.026") remains within typical PCB assembly tolerances for 0805 packages and does not preclude direct substitution in standard surface-mount designs.

Selection between these parts should be based on application power requirements, supply chain availability, and any specific automotive or industrial certification mandates. Both components are suitable for current sensing circuits operating within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6BWFR036V replace CSR0805FT36L0 in all applications?

A: Yes, provided the application does not have specific manufacturer or series requirements. The substitute maintains identical electrical specifications (36 mOhms ±1%) and package dimensions (0805 / 2012 Metric). The higher power rating (0.5W vs. 0.25W) is compatible with all designs using the original part.

Q: What is the significance of the power rating difference?

A: The ERJ-6BWFR036V is rated for 0.5W (1/2W) compared to the CSR0805FT36L0 at 0.25W (1/4W). This allows the substitute to dissipate twice the power without thermal degradation. In current sensing applications, this provides additional thermal margin and reliability. If the original design operates below 0.25W dissipation, the substitute performs identically.

Q: Are there physical compatibility concerns?

A: Both parts use the 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). The seated height difference (0.030" vs. 0.026") is 0.004" (0.10mm) and falls within standard PCB assembly tolerances. No design modifications are required for direct substitution.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard for passive components. The ERJ-6BWFR036V meets enhanced reliability and testing requirements for automotive applications. This certification is not required for general industrial use but provides additional assurance for automotive or mission-critical designs.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CSR0805FT36L0 and ERJ-6BWFR036V are RoHS3 compliant with unlimited moisture sensitivity (MSL 1), meeting current environmental and regulatory requirements.

Q: What is the temperature coefficient specification?

A: The CSR0805FT36L0 specifies ±200ppm/°C. The ERJ-6BWFR036V specifies 0 / +200ppm/°C, indicating a tighter lower bound. Both remain within acceptable tolerance drift across the -55°C to 155°C operating range for current sensing applications.
