ZRC330F02TC Equivalent & Substitute Parts

Part Overview

The ZRC330F02TC is a shunt voltage reference IC manufactured by Diodes Incorporated, designed to provide a fixed 3.3V output with ±2% tolerance. This Surface Mount device in SOT-23-3 packaging is classified as a Power Management (PMIC) component and is currently listed as Obsolete. Due to its obsolete status, identifying equivalent substitute parts is essential for ongoing design support, production continuity, and component sourcing in applications requiring stable voltage reference functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZRC330F02TC is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Type: Fixed
• Voltage - Output: 3.3V
• Current - Output: 5 mA
• Tolerance: ±2%
• Temperature Coefficient: 50ppm/°C
• Noise - 10Hz to 10kHz: 43µVrms
• Current - Cathode: 20 µA
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package / Case: SOT-23-3
• Mounting Type: Surface Mount

The ZRC330F02TA meets all these criteria and is therefore classified as a parametric equivalent. The primary distinction between the main part and its substitute is the packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The ZRC330F02TA is the direct parametric equivalent for the obsolete ZRC330F02TC. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications, thermal characteristics, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The ZRC330F02TA is currently in Active product status with substantial inventory availability (50,325 Pcs), making it the appropriate selection for new designs and production continuity. The ZRC330F02TC, being Obsolete with limited inventory (1,076 Pcs), should be phased out in favor of the ZRC330F02TA.

Both parts are supplied in SOT-23-3 packaging and are suitable for Surface Mount assembly. The primary difference is the packaging format: the ZRC330F02TC is supplied in bulk, while the ZRC330F02TA is supplied in Tape & Reel format, which is standard for automated manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the ZRC330F02TA directly replace the ZRC330F02TC in existing designs?

A: Yes. The ZRC330F02TA is a parametric equivalent with identical electrical specifications, tolerance, temperature coefficient, noise characteristics, and operating temperature range. Both parts use the same SOT-23-3 package and are Surface Mount devices. No circuit modifications are required.

Q: Why is the ZRC330F02TC listed as Obsolete?

A: The ZRC330F02TC has reached end-of-life status. The ZRC330F02TA, which is functionally identical, is the active replacement part and is recommended for all new designs and ongoing production.

Q: What is the difference between the packaging formats?

A: The ZRC330F02TC is supplied in bulk packaging, while the ZRC330F02TA is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated Surface Mount assembly processes and offers improved handling efficiency in production environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the ZRC330F02TC and ZRC330F02TA are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is based on matching Reference Type (Shunt), Output Type (Fixed), Output Voltage (3.3V), Output Current (5 mA), Tolerance (±2%), Temperature Coefficient (50ppm/°C), Noise specification (43µVrms at 10Hz to 10kHz), Cathode Current (20 µA), Operating Temperature Range (-40°C ~ 85°C), and Package Type (SOT-23-3).
