Key Parameters

Substitute Part Grouping Explanation

Substitution of the UMZC6.8NFHT106 is determined by alignment of the following critical parameters:

• Voltage - Reverse Standoff and Voltage - Breakdown characteristics within specified tolerances
• Package compatibility: SC-70 or SOT-323 surface mount packages
• Zener diode type classification
• Automotive-grade qualification (AEC-Q100 or AEC-Q101)
• RoHS3 compliance and MSL rating
• Surface mount mounting type

The substitute part BZB784-C6V8,115 meets these criteria as a Zener diode array with a nominal Zener voltage of 6.8V, packaged in SOT-323, and qualified to AEC-Q100 automotive standards.

Parameter Comparison

Engineering Selection Recommendations

The BZB784-C6V8,115 serves as a functional equivalent to the UMZC6.8NFHT106 based on the following criteria:

Both components are automotive-grade Zener diodes in SOT-323 surface mount packages with RoHS3 compliance and MSL 1 ratings. The substitute part carries AEC-Q100 qualification, meeting automotive reliability standards. The nominal Zener voltage of 6.8V on the substitute aligns with the 6.47V minimum breakdown voltage of the main part, providing compatible voltage regulation characteristics. Both components are available in tape and reel packaging for production environments.

Selection between these parts should be based on design requirements for specific voltage regulation performance, manufacturer preference, and supply chain availability.
