Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZRC330F03TC is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Voltage: 3.3V (fixed)
• Output Current: 5 mA
• Voltage Tolerance: ±3%
• Temperature Coefficient: 50ppm/°C
• Noise Performance: 43µVrms (10Hz to 10kHz)
• Operating Temperature Range: -40°C ~ 85°C
• Package: SOT-23-3 (TO-236-3, SC-59)
• Mounting: Surface Mount

The ZRC330F03TA meets all these criteria and qualifies as a parametric equivalent. Both parts share identical electrical specifications and mechanical compatibility, with the primary distinction being packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The ZRC330F03TA is the direct substitute for the ZRC330F03TC. Both parts are manufactured by Diodes Incorporated and maintain identical electrical and mechanical specifications across all critical parameters.

The ZRC330F03TA carries Active product status, ensuring continued availability and manufacturing support. This part is supplied in Tape & Reel (TR) packaging format, which is standard for production environments and automated assembly processes.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

For new designs or production continuity, the ZRC330F03TA is the appropriate selection due to its active lifecycle status and standard production packaging.

Frequently Asked Questions (FAQ)

Q: Can the ZRC330F03TA directly replace the ZRC330F03TC in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. PCB layouts, schematic designs, and assembly processes require no modification. The primary difference is product lifecycle status and packaging format.

Q: What is the difference between the ZRC330F03TC and ZRC330F03TA?

A: The ZRC330F03TC is Obsolete, while the ZRC330F03TA is Active. The ZRC330F03TC is supplied in bulk packaging, while the ZRC330F03TA is supplied in Tape & Reel (TR) format. All electrical specifications and the SOT-23-3 package remain identical.

Q: Is the SOT-23-3 package compatible with both parts?

A: Yes. Both the ZRC330F03TC and ZRC330F03TA use the SOT-23-3 package (also designated TO-236-3 or SC-59). Pin configuration, footprint, and mechanical dimensions are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) rating. Regulatory and environmental certifications are equivalent.

Q: Why should I use the ZRC330F03TA instead of the ZRC330F03TC?

A: The ZRC330F03TA carries Active product status, ensuring ongoing manufacturing support and availability through distribution channels. The ZRC330F03TC is Obsolete and subject to discontinuation. For production continuity and supply chain reliability, the ZRC330F03TA is the recommended choice.

Q: What is the output voltage tolerance for these parts?

A: Both parts maintain ±3% tolerance on the 3.3V fixed output voltage, ensuring consistent performance across the specified operating temperature range of -40°C to 85°C.
