Parameter Comparison

Engineering Selection Recommendations

The BVT-I-R005-1.0 from Isabellenhuette USA is a direct functional equivalent for the discontinued CSS2H-2512K-5L00F. Both components satisfy identical electrical specifications (5 mOhms, ±1%, 2.5W) and mechanical requirements (2512 package, identical footprint dimensions). Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are maintained.

The BVT-I-R005-1.0 offers an extended lower operating temperature limit (-65°C versus -55°C) and improved temperature coefficient performance (±50ppm/°C versus ±75ppm/°C), providing enhanced performance margins in thermal environments. The seated height of the Isabellenhuette part is 0.005" (0.13mm) lower, which may provide marginal benefits in space-constrained PCB layouts but does not affect electrical performance or mechanical compatibility.

The substitute part is currently in active production status with confirmed inventory availability, ensuring supply chain continuity for new procurement and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the BVT-I-R005-1.0 be used as a direct replacement for the CSS2H-2512K-5L00F in existing designs?

A: Yes. Both components share identical resistance (5 mOhms), tolerance (±1%), power rating (2.5W), package type (2512), and physical footprint dimensions (0.250" L x 0.120" W). Both carry AEC-Q200 automotive qualification and are ROHS3 compliant. The parts are electrically and mechanically interchangeable.

Q: Are there any PCB layout considerations when substituting these parts?

A: The BVT-I-R005-1.0 has a maximum seated height of 0.029" (0.74mm) compared to 0.034" (0.87mm) for the CSS2H-2512K-5L00F. This 0.005" difference is negligible for standard PCB designs. Both components use identical 2512 package footprints and two-terminal configurations, requiring no layout modifications.

Q: What is the difference in temperature coefficient between these parts?

A: The CSS2H-2512K-5L00F has a temperature coefficient of ±75ppm/°C, while the BVT-I-R005-1.0 has ±50ppm/°C. The Isabellenhuette part exhibits superior temperature stability with a 25ppm/°C improvement. For current sense applications, this provides tighter resistance tolerance across the operating temperature range.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the CSS2H-2512K-5L00F and BVT-I-R005-1.0 carry AEC-Q200 qualification, meeting automotive industry reliability and quality standards. Both are ROHS3 compliant and have Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the operating temperature range for each part?

A: The CSS2H-2512K-5L00F operates from -55°C to 170°C. The BVT-I-R005-1.0 operates from -65°C to 170°C, providing a 10°C lower temperature limit. Both parts support the full 170°C upper temperature specification.

Q: Are there packaging differences between these parts?

A: The CSS2H-2512K-5L00F is supplied in Cut Tape (CT) packaging, while the BVT-I-R005-1.0 is supplied in Tape & Reel (TR) packaging. Both packaging formats are standard for surface-mount components. Selection depends on procurement volume and assembly process requirements.

Q: Can these parts be used in high-current sensing applications?

A: Yes. Both components are specifically designed for current sense applications with metal element composition. The 5 mOhms resistance and 2.5W power rating support current sensing in automotive and industrial systems. The ±1% tolerance ensures accurate current measurement across the operating range.
