Engineering Selection Recommendations
The DAC7616EB serves as the direct substitute for the DAC7616EB/1K. Both components are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The primary distinction is product status: the DAC7616EB/1K is classified as obsolete, while the DAC7616EB maintains active status with current manufacturing support.
Both variants maintain ROHS3 compliance and identical MSL 3 ratings, ensuring compatibility with standard PCB assembly processes. The DAC7616EB is available in tube packaging, providing a viable alternative for procurement and inventory management.
Frequently Asked Questions (FAQ)
Q: Can the DAC7616EB directly replace the DAC7616EB/1K in existing designs?
A: Yes. Both components are electrically and mechanically identical, with matching pin configurations, electrical specifications, and package dimensions. No circuit modifications are required.
Q: What is the difference between DAC7616EB/1K and DAC7616EB?
A: The primary difference is product status and packaging configuration. The DAC7616EB/1K is obsolete, while the DAC7616EB is active. The DAC7616EB is supplied in tube packaging versus the original packaging of the DAC7616EB/1K.
Q: Are there any compliance or environmental differences between these parts?
A: No. Both components maintain identical ROHS3 compliance status and MSL 3 moisture sensitivity ratings, ensuring equivalent performance in standard manufacturing and operational environments.
Q: What are the critical parameters for substitution compatibility?
A: Substitution compatibility is determined by: 12-bit resolution, 4-channel configuration, SPI interface, 10µs settling time, 3V ~ 3.6V supply voltage ranges, ±1 LSB linearity specifications, R-2R architecture, and 20-SSOP package format.
Q: Is the 20-SSOP package footprint identical between both parts?
A: Yes. Both components use the 20-SSOP package with 0.209" width (5.30mm), ensuring identical PCB footprint and mounting compatibility.
