ZXRE330AV-A Equivalent & Substitute Parts

Part Overview

The ZXRE330AV-A is a shunt voltage reference IC manufactured by Diodes Incorporated, designed to provide a fixed 3.3V output with ±0.5% tolerance. This component is classified as a Power Management (PMIC) device and is packaged in TO-92 through-hole configuration. The product status is obsolete, making identification of equivalent alternatives essential for ongoing design support and component procurement in legacy systems or production continuity scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ZXRE330AV-A is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt voltage reference topology
• Output Voltage: Fixed 3.3V output
• Tolerance: ±0.5% accuracy specification
• Temperature Coefficient: 150 ppm/°C thermal stability
• Output Current: 5 mA rated capacity
• Package: TO-92 through-hole form factor
• Operating Temperature: -40°C to 85°C range
• Compliance: ROHS3 and REACH requirements

Only components matching all these parameters across electrical performance and mechanical form factor qualify as direct substitutes. The ZXRE330AV-A itself represents the parametric equivalent within the available inventory.

Parameter Comparison

Engineering Selection Recommendations

The ZXRE330AV-A is classified as obsolete. For applications currently using this component, direct replacement with the parametric equivalent ZXRE330AV-A maintains full electrical and mechanical compatibility. Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new production or legacy system support.

When sourcing alternatives, verify that the substitute part maintains identical specifications across output voltage (3.3V), tolerance (±0.5%), temperature coefficient (150 ppm/°C), and TO-92 package configuration. The through-hole mounting type and MSL 1 rating support standard PCB assembly processes without additional handling requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ZXRE330AV-A with a different voltage reference? A: No. The ZXRE330AV-A is specified for fixed 3.3V output. Substitutes must maintain this exact output voltage. Different voltage ratings are not interchangeable without circuit redesign.

Q: What makes the TO-92 package critical for substitution? A: The TO-92 through-hole package determines PCB layout, lead spacing, and mounting method. Substitutes must use identical TO-92-3 configuration to ensure mechanical fit and electrical connectivity without board redesign.

Q: Is the ±0.5% tolerance specification mandatory for substitution? A: Yes. The tolerance specification directly impacts circuit accuracy and performance. Substitutes with different tolerance ratings (such as ±1% or ±2%) will not meet the original design requirements.

Q: Does the temperature coefficient affect substitution eligibility? A: Yes. The 150 ppm/°C temperature coefficient is a key performance parameter. Substitutes must match this specification to maintain output stability across the -40°C to 85°C operating range.

Q: Are there compliance considerations for substitute selection? A: Yes. Both the main part and any substitute must maintain ROHS3 compliance and REACH unaffected status. These certifications are mandatory for production use in regulated markets.

Q: Can I use a surface-mount equivalent instead of the through-hole TO-92? A: No. Surface-mount packages (such as SOT-23 or SOT-89) are not compatible substitutes. The through-hole TO-92 package is mechanically and electrically distinct and cannot be interchanged without PCB redesign.
