• Identical temperature coefficient (±200ppm/°C)
• Identical operating temperature range (-55°C ~ 155°C)
• Same composition (Thick Film) and current sense feature
• Same RoHS and MSL compliance

Upgrade Substitute (Enhanced Power Rating with Automotive Qualification):

• Identical resistance value (20 mOhms)
• Identical tolerance (±1%)
• Identical package (0805 / 2012 Metric)
• Higher power rating (0.5W vs. 0.25W)
• Temperature coefficient within acceptable range (0/+200ppm/°C)
• Identical operating temperature range (-55°C ~ 155°C)
• Same composition (Thick Film) and current sense feature
• Additional automotive qualification (AEC-Q200)
• Same RoHS and MSL compliance

Parameter Comparison

Engineering Selection Recommendations

CSR0805FK20L0 serves as a direct equivalent to CSR0805FT20L0. Both parts share identical electrical specifications, package dimensions, and compliance certifications. Selection between these two Stackpole parts depends on inventory availability and procurement lead times. Both maintain Active product status and ROHS3 compliance.

ERJ-6BWFR020V (Panasonic) functions as an upgrade substitute when higher power dissipation capability is required. The 0.5W rating provides additional thermal margin compared to the 0.25W rating of the primary part, while maintaining identical resistance, tolerance, and package form factor. The inclusion of AEC-Q200 automotive qualification makes this part suitable for automotive and high-reliability applications. The temperature coefficient specification (0/+200ppm/°C) remains within acceptable operating parameters. This part is appropriate for designs requiring enhanced power handling or automotive-grade components within the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can CSR0805FK20L0 be used as a direct replacement for CSR0805FT20L0?

A: Yes. CSR0805FK20L0 is a direct equivalent with identical electrical and mechanical specifications, including resistance value, tolerance, power rating, package dimensions, and operating temperature range. Both parts are manufactured by Stackpole Electronics Inc and carry identical compliance certifications.

Q: What is the primary difference between CSR0805FT20L0 and ERJ-6BWFR020V?

A: The primary difference is power rating. ERJ-6BWFR020V is rated for 0.5W (1/2W) compared to 0.25W (1/4W) for CSR0805FT20L0. Additionally, ERJ-6BWFR020V carries AEC-Q200 automotive qualification. All other electrical parameters, including resistance, tolerance, and operating temperature range, remain identical. Both use the same 0805 (2012 Metric) package.

Q: Is ERJ-6BWFR020V suitable for non-automotive applications?

A: Yes. ERJ-6BWFR020V meets all electrical and mechanical requirements for general industrial and commercial applications. The automotive qualification is an additional certification that does not restrict use in other application categories. The higher power rating may provide design benefits in applications with elevated thermal requirements.

Q: Are there any dimensional differences between these parts?

A: All three parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Maximum seated height differs slightly: CSR0805FT20L0 and CSR0805FK20L0 are 0.026" (0.65mm), while ERJ-6BWFR020V is 0.030" (0.75mm). This minor height difference is typically accommodated within standard PCB assembly tolerances.

Q: What packaging formats are available for these parts?

A: CSR0805FT20L0 and CSR0805FK20L0 are supplied in Tape & Reel (TR) format. ERJ-6BWFR020V is available in Cut Tape (CT) and Digi-Reel® formats. Packaging selection should align with assembly equipment and procurement requirements.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. CSR0805FT20L0, CSR0805FK20L0, and ERJ-6BWFR020V are all ROHS3 compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control measures are required during storage or handling.
