Replacement verdict
Compatible functional replacement candidate
The AD9754ARUZRL7 and AD9754ARU are functionally equivalent 14-bit high-speed DACs from the same AD9754 family, sharing identical core specifications including resolution, update rate, and supply requirements. The primary distinction lies in packaging and delivery format, with the ARUZRL7 supplied in tape-and-reel packaging with RoHS-compliant construction, while the ARU is provided in tube packaging. Both parts are suitable for drop-in substitution in most designs, provided the assembly process accommodates the respective packaging format and the design does not require the specific RoHS compliance status of the ARUZRL7 variant.

Key electrical and mechanical differences between the two devices
| Parameter | AD9754ARUZRL7 | AD9754ARU | Why it matters |
|---|---|---|---|
| Resolution | 14 bit | 14 bit | Determines the quantization precision of the DAC output; identical resolution means equivalent signal fidelity. |
| Number of DAC Channels | 1 | 1 | Single-channel architecture must match for direct functional substitution in a circuit. |
| Sampling Rate | 125 Msps | 125 Msps | Maximum update rate defines the bandwidth the DAC can support; identical rates ensure equivalent dynamic performance. |
| Output Type | Current - Unbuffered | Current - Unbuffered | Output configuration must match to interface correctly with downstream analog stages. |
| Supply Voltage | 5 V (Analog and Digital) | 5 V (Analog and Digital) | Supply requirements must be compatible with the existing power rail design. |
| Package / Case | 28-TSSOP | 28-TSSOP | Footprint and pinout must match for drop-in board replacement. |
| Mounting Type | Surface Mount | Surface Mount | Assembly method must be compatible with the PCB manufacturing process. |
| Operating Temperature Range | -40°C to 85°C | -40°C to 85°C | Thermal range must cover the application environment for reliable operation. |
| Packaging | Tape & Reel (RL7) | Tube | Packaging form affects handling and assembly line feed method, though the device itself is functionally identical. |

Frequently asked questions
What are the key differences between AD9754ARUZRL7 and AD9754ARU?
Both parts are the same AD9754 14-bit, 125 MSPS TxDAC+ digital-to-analog converter from Analog Devices. The AD9754ARU is supplied in a 28-lead TSSOP tube packaging, while the AD9754ARUZRL7 is the RoHS-compliant (Z) version supplied in 7-inch tape-and-reel packaging (RL7). The core die, performance specifications, and functional pinout are identical.
Are AD9754ARUZRL7 and AD9754ARU electrically and functionally interchangeable?
Yes. Both variants share the same 14-bit resolution, 125 MSPS update rate, on-chip 1.20 V reference, and 5 V or 3.3 V supply operation. The only differences are the RoHS compliance designation (Z suffix) and the packaging format (tape-and-reel vs tube), so they are functionally interchangeable in the same PCB footprint.
What is the package and pin count for these devices?
Both AD9754ARUZRL7 and AD9754ARU are offered in a 28-lead TSSOP (Thin Shrink Small Outline Package). The pinout is identical between the two variants, allowing the same PCB land pattern to be used.
Does the AD9754ARUZRL7 meet RoHS requirements while the AD9754ARU does not?
The "Z" in AD9754ARUZRL7 denotes RoHS compliance per Analog Devices' part numbering convention. The AD9754ARU (without Z) is the non-RoHS version. Designers requiring RoHS compliance for export or regulatory reasons should select the AD9754ARUZRL7.
What is the difference in packaging quantity between the two variants?
The AD9754ARUZRL7 is supplied in a 7-inch tape-and-reel format intended for automated pick-and-place assembly, typically in reels of 1,000 or 1,500 units depending on the reel size. The AD9754ARU is supplied in tubes for manual or low-volume assembly. Reel quantity should be confirmed against the current Analog Devices datasheet or distributor listing.
Can AD9754ARU be used as a drop-in replacement for AD9754ARUZRL7 in an existing design?
Yes, from an electrical and footprint standpoint the two are drop-in compatible because they share the same die, pinout, and 28-lead TSSOP package. The only consideration is RoHS compliance: if the design mandates lead-free/RoHS-compliant components, the AD9754ARUZRL7 should be used instead of the non-Z AD9754ARU.
What are the supply voltage and resolution specifications common to both parts?
Both AD9754ARUZRL7 and AD9754ARU are 14-bit DACs with a maximum update rate of 125 MSPS, operating from a single 5 V or 3.3 V supply with a separate digital supply of 2.7 V to 5.5 V. They include an on-chip 1.20 V bandgap reference and provide a differential current output of 2 mA to 20 mA.
