Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR0805FT30L0 is determined by the following critical parameters: resistance value (30 mOhms), tolerance (±1%), package type (0805), composition (thick film), and operating temperature range (-55°C to 155°C). Parts meeting these core specifications are classified as direct substitutes. Parts with identical electrical characteristics but enhanced power ratings or automotive qualifications are classified as upgrades, suitable for applications requiring higher thermal performance or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

CSR0805FK30L0 serves as a direct substitute for CSR0805FT30L0, maintaining identical electrical specifications, power rating, and thermal characteristics. Both parts are manufactured by Stackpole Electronics Inc and carry active product status with full ROHS3 compliance.

ERJ-6BWFR030V is classified as an upgrade option. While maintaining the same resistance, tolerance, package, and operating temperature range, this Panasonic component provides doubled power dissipation capability (0.5W versus 0.25W) and includes AEC-Q200 automotive qualification. The temperature coefficient specification differs slightly (0/+200ppm/°C versus ±200ppm/°C). This part is suitable for applications requiring enhanced thermal margin or automotive-grade reliability assurance.

Frequently Asked Questions (FAQ)

Q: Can CSR0805FK30L0 be used as a direct replacement for CSR0805FT30L0?

A: Yes. Both parts share identical resistance (30 mOhms), tolerance (±1%), power rating (0.25W), package (0805), composition (thick film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 155°C). They are functionally equivalent.

Q: What is the primary difference between CSR0805FT30L0 and ERJ-6BWFR030V?

A: The ERJ-6BWFR030V provides double the power rating (0.5W versus 0.25W) and includes AEC-Q200 automotive qualification. Electrical parameters remain identical. This upgrade is suitable for designs requiring higher thermal performance or automotive compliance.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). PCB layout compatibility is maintained across all substitutes.

Q: What does ROHS3 compliance mean for these parts?

A: ROHS3 compliance indicates the parts meet Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. All three parts carry this certification.

Q: Can ERJ-6BWFR030V be used in applications originally designed for CSR0805FT30L0?

A: Yes. The ERJ-6BWFR030V meets or exceeds all electrical and thermal specifications of the original part. The higher power rating and automotive qualification provide additional design margin without compromising compatibility.
