DAC813KP Equivalent & Substitute Parts

Part Overview

The DAC813KP is a 12-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring voltage output conversion. This component features an R-2R architecture with external and internal reference capability, operating across a wide supply voltage range of ±11.4V to 16.5V. The DAC813KP is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations. The primary substitute maintains identical electrical specifications while offering improved product status and alternative packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC813KP is based on strict electrical and mechanical parameter matching within the DAC813 product family. The substitute part DAC813KU maintains identical core electrical specifications: 12-bit resolution, single converter configuration, 6µs settling time, buffered voltage output, parallel data interface, dual reference capability, and matching supply voltage ranges. Both parts share the same INL/DNL performance characteristics (±0.125, ±0.25 LSB), R-2R architecture, and operating temperature range (-40°C to 85°C).

The key differentiator between these parts is packaging format: the DAC813KP uses 28-DIP (0.300", 7.62mm) through-hole mounting, while the DAC813KU uses 28-SOIC (0.295", 7.50mm Width) surface-mount packaging. Both maintain ROHS3 compliance and identical electrical performance, making them functionally equivalent for applications where the mounting technology can be accommodated.

Parameter Comparison

Engineering Selection Recommendations

The DAC813KU is the designated manufacturer substitute for the obsolete DAC813KP. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The DAC813KU carries active product status, ensuring continued availability and manufacturer support, whereas the DAC813KP is obsolete.

Selection between these parts depends on circuit board design constraints. The DAC813KP requires through-hole mounting on DIP-compatible sockets or PCB pads. The DAC813KU requires surface-mount assembly capability on SOIC footprints. Both deliver identical electrical performance and precision specifications.

The DAC813KU has a higher moisture sensitivity level (MSL 3, 168 hours) compared to the DAC813KP (MSL 1, unlimited), which may affect storage and handling procedures in high-humidity environments. This difference does not impact electrical equivalence but requires appropriate moisture control during component storage and assembly.

Frequently Asked Questions (FAQ)

Q: Are the DAC813KP and DAC813KU electrically equivalent? A: Yes. Both components share identical electrical specifications including 12-bit resolution, 6µs settling time, buffered voltage output, parallel data interface, dual reference capability, and matching supply voltage ranges (±11.4V to 16.5V). INL/DNL performance is identical at ±0.125 and ±0.25 LSB.

Q: What is the primary difference between these parts? A: The DAC813KP uses 28-DIP through-hole packaging, while the DAC813KU uses 28-SOIC surface-mount packaging. The DAC813KU is the active product with current manufacturer support, whereas the DAC813KP is obsolete.

Q: Can I use the DAC813KU as a direct replacement for the DAC813KP? A: Electrical substitution is direct. However, physical board layout and assembly process must accommodate the different package types. DIP through-hole designs require redesign for SOIC surface-mount implementation.

Q: What are the moisture sensitivity differences? A: The DAC813KP has MSL 1 (unlimited moisture exposure tolerance), while the DAC813KU has MSL 3 (168-hour moisture exposure limit). The DAC813KU requires appropriate moisture control during storage and assembly in humid environments.

Q: Are both parts RoHS compliant? A: Yes. Both the DAC813KP and DAC813KU are ROHS3 compliant and REACH unaffected.

Q: Why is the DAC813KP listed as obsolete? A: The DAC813KP is obsolete due to product lifecycle management by Texas Instruments. The DAC813KU represents the current active product offering with equivalent electrical specifications.
