Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZRC330F01TC is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for:

• Reference type (Shunt)
• Output voltage (3.3V fixed)
• Output current capability (5 mA)
• Voltage tolerance (±1%)
• Temperature coefficient (50ppm/°C)
• Noise performance (43µVrms across 10Hz to 10kHz band)
• Cathode current (20 µA)
• Operating temperature range (-40°C ~ 85°C)
• Package configuration (SOT-23-3)
• Compliance certifications (ROHS3, REACH Unaffected)

The ZRC330F01TA meets all these criteria and serves as a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ZRC330F01TA is the direct substitute for the obsolete ZRC330F01TC. Both parts are manufactured by Diodes Incorporated and share identical electrical and mechanical specifications. The primary distinction is product status: the ZRC330F01TC is obsolete while the ZRC330F01TA maintains active production status.

Selection of the ZRC330F01TA is supported by:

• Full parametric equivalence across all specified electrical characteristics
• Identical package configuration (SOT-23-3) ensuring mechanical compatibility
• Matching compliance certifications (ROHS3 Compliant, REACH Unaffected)
• Equivalent moisture sensitivity rating (MSL 1)
• Active product status ensuring continued availability and supply chain support

Frequently Asked Questions (FAQ)

Q: Can the ZRC330F01TA be used as a direct replacement for the ZRC330F01TC?
