Active product status and ROHS3 compliance ensure supply continuity.

UCR10EVHFSR068 (Rohm Semiconductor)

This substitute offers the tightest tolerance specification (±1%) with enhanced power rating (0.333W) and Automotive AEC-Q200 qualification. The UCR10EVHFSR068 delivers superior temperature coefficient performance and extended operating temperature range. Active product status and ROHS3 compliance support regulatory and supply requirements. This option provides the highest performance margin for current sense applications.

Frequently Asked Questions (FAQ)

Q: Can CSR0805JT68L0 be used as a direct replacement for 1-1622821-7?

A: Yes. The CSR0805JT68L0 maintains identical resistance (68 mOhms), tolerance (±5%), power rating (0.25W), and package configuration (0805). Both components are thick film current sense resistors with MSL 1 moisture sensitivity rating. The substitute offers improved temperature coefficient and extended operating temperature range.

Q: What is the difference between the two Rohm Semiconductor options?

A: UCR10EVHJSR068 and UCR10EVHFSR068 differ in tolerance specification. The UCR10EVHJSR068 maintains ±5% tolerance matching the original part, while UCR10EVHFSR068 provides tighter ±1% tolerance. Both share identical power rating (0.333W), AEC-Q200 qualification, and operating temperature range (-55°C ~ 155°C).

Q: Are the substitute parts physically compatible with the original PCB layout?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height variations are minimal (0.020" to 0.026" seated maximum), within standard PCB assembly tolerances.

Q: Do the substitute parts support automotive applications?

A: The Rohm Semiconductor options (UCR10EVHJSR068 and UCR10EVHFSR068) carry AEC-Q200 automotive qualification. The Stackpole Electronics CSR0805JT68L0 does not specify automotive qualification. Selection depends on application requirements.

Q: What is the impact of tolerance differences on circuit performance?

A: The original 1-1622821-7 and CSR0805JT68L0 both specify ±5% tolerance. The UCR10EVHFSR068 provides ±1% tolerance, reducing resistance variation from ±3.4 mOhms to ±0.68 mOhms. This tighter tolerance improves current measurement accuracy in sensing circuits.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CSR0805JT68L0, UCR10EVHJSR068, and UCR10EVHFSR068 are all ROHS3 compliant. The original 1-1622821-7 does not specify RoHS status.

Q: What is the significance of temperature coefficient differences?

A: The original part specifies ±350ppm/°C temperature coefficient. Substitute parts offer improved performance: CSR0805JT68L0 at ±200ppm/°C, and both Rohm options at 0/+150ppm/°C. Lower temperature coefficients reduce resistance drift across the operating temperature range, improving circuit stability.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the constraints of the specified parameters. All substitute parts maintain the 68 mOhm resistance, 0805 package, and current sense thick film composition. Designs requiring specific tolerance, power rating, or automotive qualification should select accordingly.
