DAC7624P Equivalent & Substitute Parts

Part Overview

The DAC7624P is a 12-bit digital-to-analog converter (DAC) with four independent output channels, manufactured by Texas Instruments in a 28-pin DIP package. This component features voltage-buffered outputs, external reference capability, and parallel data interface architecture. The DAC7624P is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part maintains ROHS3 compliance and operates across the industrial temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC7624P is determined by electrical and functional equivalence across the following critical parameters: 12-bit resolution, four independent D/A converter channels, voltage-buffered output configuration, parallel data interface, external reference architecture, 10µs settling time, R-2R topology, ±5V analog supply, 5V digital supply, and operating temperature range of -40°C to 85°C.

The DAC7624U qualifies as a direct functional substitute based on identical electrical specifications and performance characteristics. The primary distinction between these parts is packaging format: the DAC7624P uses through-hole 28-DIP mounting, while the DAC7624U employs surface-mount 28-SOIC technology. Both parts maintain ROHS3 compliance and are manufactured by Texas Instruments under the same base product number (DAC7624).

Parameter Comparison

Engineering Selection Recommendations

The DAC7624U is the manufacturer-recommended substitute for the obsolete DAC7624P. Both parts maintain identical electrical performance and ROHS3 compliance certification. The DAC7624U carries active product status, ensuring continued availability and manufacturing support from Texas Instruments.

Selection between these parts depends on circuit board design requirements. The DAC7624P through-hole 28-DIP package suits legacy designs and breadboard prototyping applications. The DAC7624U surface-mount 28-SOIC package is appropriate for modern PCB designs requiring compact form factors and automated assembly processes. Pin-to-pin functional compatibility exists between both packages, provided the circuit layout accommodates the different mounting technologies and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the DAC7624U directly replace the DAC7624P in existing designs?

A: Electrical substitution is complete. The DAC7624U provides identical functional performance and electrical specifications. Physical board layout modification is required due to different package formats: 28-DIP (through-hole) versus 28-SOIC (surface-mount). Pin assignments remain functionally equivalent.

Q: What is the primary reason for substituting the DAC7624P?

A: The DAC7624P is classified as obsolete. The DAC7624U maintains active product status and ensures long-term component availability from Texas Instruments.

Q: Are there compliance differences between DAC7624P and DAC7624U?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity levels differ: DAC7624P is MSL 1 (unlimited), while DAC7624U is MSL 3 (168 hours). This affects storage and handling requirements for the surface-mount variant.

Q: What are the package dimension differences?

A: The DAC7624P 28-DIP package measures 0.600 inches (15.24mm) in width. The DAC7624U 28-SOIC package measures 0.295 inches (7.50mm) in width, providing significant space reduction for surface-mount applications.

Q: Do supply voltage requirements differ between these parts?

A: No. Both the DAC7624P and DAC7624U require identical analog supply (±5V) and digital supply (5V) voltages.
