Engineering Selection Recommendations

Primary Selection: 0ZTK0010FF2G

The 0ZTK0010FF2G remains the primary component choice when available. This part carries Active product status, full AEC-Q200 automotive qualification, and documented inventory availability of 3713 pieces. The component is RoHS3 compliant and carries approvals from cURus, TUV, and UL agencies.

Substitute Selection: PICOASMDCH010F-2

The PICOASMDCH010F-2 from Littelfuse Inc. is a qualified substitute when the primary part is unavailable. This component meets all critical electrical specifications including 16V maximum voltage, 100 mA hold current, and 600 mA trip current. The part maintains AEC-Q200 automotive qualification and RoHS3 compliance. Physical dimensions are within compatible tolerances for 0805 (2012 Metric) surface mount applications. The post-trip resistance (R1) maximum of 10 Ohms is superior to the primary part specification of 12 Ohms, providing enhanced performance characteristics. Documented inventory of 1434 pieces supports supply chain continuity.

Both parts are classified as Active products with equivalent operating temperature ranges of -40°C to 125°C and identical moisture sensitivity levels of 2A (4 Weeks).

Frequently Asked Questions (FAQ)

Q: Can PICOASMDCH010F-2 be used as a direct replacement for 0ZTK0010FF2G in production?

A: Yes. The PICOASMDCH010F-2 meets all specified electrical parameters, package dimensions, and regulatory requirements. Both components are AEC-Q200 qualified, RoHS3 compliant, and rated for identical voltage, current, and temperature specifications. Physical dimensions are compatible within 0805 (2012 Metric) surface mount assembly tolerances.

Q: What is the difference in post-trip resistance between these parts?

A: The 0ZTK0010FF2G specifies a maximum post-trip resistance (R1) of 12 Ohms, while the PICOASMDCH010F-2 specifies 10 Ohms maximum. The lower resistance value of the substitute part provides equivalent or improved performance in circuit applications.
