DAC63204RTER Equivalent & Substitute Parts

Part Overview

The DAC63204RTER is a 12-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring buffered voltage or current output. This device integrates four independent D/A converters in a compact 16-WQFN surface-mount package with an exposed pad. The part is currently in active production status with 6400 units available in inventory.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and functional specifications align with the main part's operational requirements. Alternative models may be necessary due to inventory availability, supply chain considerations, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC63204RTER is determined by strict alignment across the following critical parameters:

Electrical Specifications:

• 12-bit resolution
• 4 independent D/A converter channels
• Buffered voltage or current output capability
• I2C and SPI digital interface support
• Analog supply voltage range: 1.71V ~ 5.5V
• Digital supply voltage range: 1.62V ~ 5.5V
• Settling time: 25µs (typical)
• INL/DNL: ±4LSB, ±1

Mechanical & Package Specifications:

• 16-WQFN (3x3) package with exposed pad
• Surface-mount technology
• Operating temperature: -40°C ~ 125°C

Compliance & Status:

• Active product status
• ROHS3 compliance
• Texas Instruments manufacturer

The DAC63004RTER meets all electrical and mechanical substitution criteria. Both parts belong to the DACx3204 series and share identical functional specifications, interface protocols, and package geometry. The primary distinction is the moisture sensitivity level classification.

Parameter Comparison

Engineering Selection Recommendations

Both the DAC63204RTER and DAC63004RTER are active, ROHS3-compliant products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Moisture Sensitivity Considerations: The DAC63204RTER carries an MSL rating of 2 with a 1-year shelf life, while the DAC63004RTER carries an MSL rating of 1 with unlimited shelf life. MSL classification affects storage conditions and handling procedures. Lower MSL ratings (MSL 1) indicate greater tolerance to moisture exposure and longer storage viability without desiccant packaging.

Inventory & Availability: The DAC63204RTER has 6400 units in stock, while the DAC63004RTER has 3400 units available. Selection may be influenced by immediate availability requirements.

Application Suitability: Both parts are suitable for identical applications requiring 12-bit, 4-channel D/A conversion with buffered output, I2C/SPI interface, and surface-mount integration. The choice between them does not affect functional performance in the circuit.

Compliance Status: Both parts meet ROHS3 compliance requirements and carry identical ECCN and HTSUS classifications, ensuring equivalent regulatory and trade compliance.

Frequently Asked Questions (FAQ)

Q: Can the DAC63004RTER be used as a direct replacement for the DAC63204RTER?

A: Yes. The DAC63004RTER is electrically and mechanically equivalent to the DAC63204RTER. All functional specifications, interface protocols, package geometry, and performance parameters are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between MSL 2 and MSL 1 ratings?

A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture during storage and handling. MSL 2 components require storage in desiccant packaging and have a 1-year shelf life from the date of manufacture. MSL 1 components have unlimited shelf life and greater tolerance to moisture exposure. The DAC63004RTER's MSL 1 rating provides more flexible storage and handling conditions.

Q: Are the pin configurations identical between these parts?

A: Yes. Both the DAC63204RTER and DAC63004RTER use the 16-WQFN (3x3) package with exposed pad. Pin assignments, signal routing, and PCB footprint requirements are identical.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. No design changes, PCB modifications, or firmware updates are required when substituting between these parts. They are pin-compatible and functionally equivalent.

Q: What supply voltage ranges do these parts support?

A: Both parts support analog supply voltages from 1.71V to 5.5V and digital supply voltages from 1.62V to 5.5V. This wide supply range accommodates both single-supply and dual-supply configurations.

Q: Do both parts support the same communication protocols?

A: Yes. Both the DAC63204RTER and DAC63004RTER support I2C and SPI digital interfaces, enabling identical communication configurations in host systems.

Q: What is the settling time specification for these converters?

A: Both parts have a typical settling time of 25µs, ensuring consistent transient response characteristics in data acquisition applications.

Q: Are there any temperature range limitations?

A: Both parts operate across the industrial temperature range of -40°C to 125°C, supporting applications in standard and extended-temperature environments.
