Replacement verdict
Compatible functional replacement candidate
The AD9739ABBCZ and AD9739ABBCZRL are functionally identical 14-bit, 2.5 GSPS RF digital-to-analog converters from Analog Devices, differing only in packaging format (tray vs. tape-and-reel). Both share the same die, electrical specifications, and BGA-160 package, making them fully interchangeable for design and production purposes; the choice between them is purely a matter of manufacturing handling preference.

Key electrical and mechanical differences between the two devices
| Parameter | AD9739ABBCZ | AD9739ABBCZRL | 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 | Defines whether the device is single or multi-channel; both are single-channel, so they are functionally interchangeable. |
| Sampling Rate (Max) | 2.5 GSPS | 2.5 GSPS | Sets the maximum update rate and achievable output bandwidth; identical rates ensure the same application range. |
| Output Type | Current - Unbuffered | Current - Unbuffered | Determines the interface circuitry required at the DAC output; matching types allow drop-in substitution. |
| Supply Voltage | 1.8 V / 3.3 V | 1.8 V / 3.3 V | Confirms power rail compatibility; identical rails mean the same board power design can be reused. |
| Package / Case | 160-LFBGA, CSPBGA | 160-LFBGA, CSPBGA | Ensures physical footprint and solderability match; identical packages allow the same PCB land pattern. |
| Operating Temperature Range | -40°C to 85°C | -40°C to 85°C | Defines the environmental envelope; matching ranges mean equivalent reliability in the same conditions. |
| Packaging / Mounting Format | Tray | Tape & Reel (RL) | Affects manufacturing handling and assembly line feed method; the "RL" suffix denotes reel packaging versus tray. |
| Mounting Type | Surface Mount | Surface Mount | Confirms the assembly process compatibility; both are surface-mount devices. |

Frequently asked questions
What is the difference between AD9739ABBCZ and AD9739ABBCZRL?
The AD9739ABBCZ and AD9739ABBCZRL are the same AD9739A 14-bit, 2.5 GSPS RF digital-to-analog converter in a 160-ball CSP-BGA package. The difference is packaging format: AD9739ABBCZ is supplied in tray packaging, while AD9739ABBCZRL is supplied in tape-and-reel packaging for automated assembly. Both share identical die, electrical specifications, and temperature range.
Are AD9739ABBCZ and AD9739ABBCZRL electrically and functionally identical?
Yes. Both orderable part numbers correspond to the same AD9739A device, a 14-bit, 2.5 GSPS DAC with LVDS input interface and current-steering output. Datasheet parameters such as resolution, update rate, SFDR, and power consumption apply equally to both variants; only the shipping container differs.
Can AD9739ABBCZRL be used as a drop-in replacement for AD9739ABBCZ?
Yes, from a design perspective. Both are the same 160-ball CSP-BGA device with identical pinout and footprint, so a board designed for AD9739ABBCZ will accept AD9739ABBCZRL. The only practical consideration is assembly handling, since the RL variant is tape-and-reel and the non-RL variant is tray.
Which variant should be selected for high-volume automated PCB assembly?
AD9739ABBCZRL is the appropriate choice for high-volume SMT production because tape-and-reel packaging is compatible with automated pick-and-place feeders. AD9739ABBCZ in trays is typically preferred for prototyping, low-volume runs, or manual assembly.
Do AD9739ABBCZ and AD9739ABBCZRL share the same operating temperature range and package?
Yes. Both are offered in the same 160-ball CSP-BGA package and are specified over the industrial temperature range of −40°C to +85°C, as documented in the Analog Devices AD9739A datasheet. Packaging format does not affect the temperature rating.
Is the moisture sensitivity level the same for both orderable part numbers?
Yes. Because both variants use the identical CSP-BGA package and construction, the moisture sensitivity level (MSL) rating published by Analog Devices applies equally to AD9739ABBCZ and AD9739ABBCZRL. Refer to the manufacturer datasheet and packaging information for the specific MSL value before reflow.
Are AD9739ABBCZ and AD9739ABBCZRL RoHS compliant?
Both part numbers use the "Z" suffix in the Analog Devices ordering code, which denotes RoHS-compliant, lead-free construction. The tape-and-reel versus tray difference does not change the RoHS status of the device itself.
