Engineering Selection Recommendations

The DSC8001CI1 serves as the direct substitute for the obsolete DSC8002CC1. Both components share identical electrical and mechanical specifications across all critical substitution parameters. The DSC8001CI1 carries Active product status, ensuring continued availability and manufacturer support.

The DSC8001CI1 provides extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and includes AEC-Q100 automotive qualification, offering enhanced reliability for demanding applications. Maximum supply current increases from 10mA to 12.2mA, and standby current increases from 1 µA to 15 µA. These differences do not affect functional compatibility in applications designed for the DSC8002CC1.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, supporting standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the DSC8001CI1 directly replace the DSC8002CC1 in existing designs?

A: Yes. The DSC8001CI1 matches all critical electrical and mechanical parameters of the DSC8002CC1, including frequency range, supply voltage, output type, package configuration, and physical dimensions. No circuit modifications are required.

Q: What are the differences between these parts?

A: The DSC8001CI1 extends the operating temperature range to -40°C to 85°C and includes AEC-Q100 automotive qualification. Maximum supply current is 12.2mA compared to 10mA, and standby current is 15 µA compared to 1 µA. The DSC8001CI1 is Active status while the DSC8002CC1 is Obsolete.

Q: Are there any thermal or power consumption concerns when substituting?

A: The increased maximum supply current (12.2mA versus 10mA) and standby current (15 µA versus 1 µA) should be evaluated within the context of system power budgets. Applications with strict power constraints should confirm compatibility with these specifications.
