REF3233AMDBVREP Equivalent & Substitute Parts

Part Overview

The REF3233AMDBVREP is a series voltage reference IC manufactured by Texas Instruments, designed to provide a fixed 3.3V output with ±0.2% tolerance. This Surface Mount device in SOT-23-6 package is classified as a Power Management (PMIC) component and is currently discontinued at DiGi Electronics. Due to its discontinued status, identifying equivalent substitute parts is essential for ongoing design support, production continuity, and component sourcing in applications requiring precision voltage reference functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the REF3233AMDBVREP are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:

• Output Voltage: Must be 3.3V fixed
• Output Current: Must be 10 mA minimum
• Package / Case: Must be SOT-23-6 (Surface Mount)
• Reference Type: Must be Series voltage reference
• Mounting Type: Must be Surface Mount

The substitute parts ADR3433ARJZ-R2 and ADR3433ARJZ-R7, both manufactured by Analog Devices Inc., meet all mechanical and primary electrical requirements. Both devices are active products with improved electrical performance characteristics compared to the discontinued REF3233AMDBVREP.

Parameter Comparison

Engineering Selection Recommendations

Both ADR3433ARJZ-R2 and ADR3433ARJZ-R7 are active products from Analog Devices Inc. and serve as direct functional replacements for the discontinued REF3233AMDBVREP. Both substitute parts are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements as the original component.

The ADR3433ARJZ-R2 and ADR3433ARJZ-R7 differ only in packaging configuration (Cut Tape vs. Digi-Reel) and inventory availability. Both devices provide superior electrical performance with improved tolerance (±0.1% vs. ±0.2%), lower temperature coefficient (8 ppm/°C vs. 40 ppm/°C), reduced noise characteristics, and lower supply current consumption (100 µA vs. 120 µA).

The ADR3433ARJZ-R7 offers significantly higher inventory availability (51,500 Pcs) compared to ADR3433ARJZ-R2 (3,276 Pcs), making it the preferred choice for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can ADR3433ARJZ-R2 and ADR3433ARJZ-R7 be used interchangeably with REF3233AMDBVREP?

A: Yes. Both substitute parts provide the same 3.3V fixed output, 10 mA output current, and SOT-23-6 package configuration. The electrical performance of the substitute parts exceeds the original specification.

Q: What is the difference between ADR3433ARJZ-R2 and ADR3433ARJZ-R7?

A: Both parts are electrically identical. The difference is in packaging format: ADR3433ARJZ-R2 is supplied in Cut Tape (CT) & Digi-Reel format with lower inventory, while ADR3433ARJZ-R7 is also supplied in Cut Tape (CT) & Digi-Reel format with significantly higher inventory availability.

Q: Are there any temperature range limitations when substituting?

A: The substitute parts operate from -40°C to 125°C, compared to the original part's -55°C to 125°C range. Applications requiring operation below -40°C require design review.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both ADR3433ARJZ-R2 and ADR3433ARJZ-R7 are ROHS3 compliant and REACH unaffected, matching the original REF3233AMDBVREP compliance status.

Q: What are the moisture sensitivity considerations?

A: The substitute parts have Moisture Sensitivity Level 1 (Unlimited shelf life), which is superior to the original part's MSL 2 (1 Year). This provides better long-term storage reliability.
