Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZRC500F02TC is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Voltage: 5V fixed
• Output Current: 5 mA
• Tolerance: ±2%
• Temperature Coefficient: 90ppm/°C
• Noise Performance: 105µVrms (10Hz to 10kHz)
• Cathode Current: 25 µA
• Operating Temperature Range: -40°C ~ 85°C
• Package: SOT-23-3 (TO-236-3, SC-59)
• Mounting: Surface Mount

The ZRC500F02TA meets all these electrical and mechanical parameters, making it a direct parametric equivalent. The primary distinction between these parts is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The ZRC500F02TA is the direct substitute for the ZRC500F02TC. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications and package geometry.

The ZRC500F02TA is recommended for new designs and ongoing production due to its Active product status, ensuring long-term availability and supply chain stability. The ZRC500F02TC, classified as Obsolete, presents procurement risk and should be replaced in active bill-of-materials documentation.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting equivalent environmental and regulatory requirements. The packaging format difference (Tube versus Tape & Reel) reflects standard industry practices for active versus obsolete product lines and does not affect electrical performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can ZRC500F02TA be used as a direct replacement for ZRC500F02TC in existing designs?

A: Yes. The ZRC500F02TA is electrically and mechanically identical to the ZRC500F02TC. Both parts feature the same 5V fixed output, ±2% tolerance, 90ppm/°C temperature coefficient, and SOT-23-3 package. No circuit modifications are required.

Q: What is the difference between ZRC500F02TC and ZRC500F02TA?

A: The primary differences are product status and packaging format. The ZRC500F02TC is Obsolete and supplied in Tube packaging, while the ZRC500F02TA is Active and supplied in Tape & Reel format. All electrical parameters and package dimensions are identical.

Q: Why is the ZRC500F02TC listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part number. The ZRC500F02TA represents the current active equivalent from Diodes Incorporated.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Will the Tape & Reel packaging of ZRC500F02TA affect assembly compatibility?

A: No. Tape & Reel packaging is standard for active production parts and is fully compatible with automated pick-and-place assembly equipment. The component itself and its SOT-23-3 footprint remain unchanged.

Q: Can these parts be used interchangeably in high-precision applications?

A: Yes. Both parts meet the same noise specification (105µVrms, 10Hz to 10kHz) and temperature coefficient (90ppm/°C), making them suitable for equivalent precision applications within the specified operating temperature range of -40°C to 85°C.
