Replacement verdict
Compatible functional replacement candidate
The AD9142ABCPZ and AD9142ABCPZRL are functionally identical dual 16-bit 1.6 GSPS DACs in the same 72-lead LFCSP package, differing only in packaging format (tray vs. tape-and-reel). The tape-and-reel variant is a drop-in replacement for automated SMT assembly lines, while the tray variant suits prototyping and low-volume runs. Both share identical electrical, thermal, and interface characteristics, making them fully interchangeable at the board level.

Key electrical and mechanical differences between the two devices
| Parameter | AD9142ABCPZ | AD9142ABCPZRL | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Determines the quantization accuracy of the DAC output; both parts share the same resolution so signal fidelity is identical. |
| Number of DAC Channels | 2 | 2 | Dual-channel architecture enables I/Q signal generation; identical channel count means the same system topology can be used. |
| Maximum Update Rate | 1600 MSPS | 1600 MSPS | Sets the maximum sample rate for wideband signal synthesis; matching rates ensure equivalent bandwidth capability. |
| Output Interface | JESD204B | JESD204B | Defines the digital input protocol and lane configuration; identical serial interface allows drop-in compatibility with the same FPGA/ASIC link. |
| Supply Voltage | 1.8 V / 3.3 V | 1.8 V / 3.3 V | Determines power rail requirements; identical rails mean the same power design can be reused. |
| Package / Case | 72-Lead LFCSP (10 x 10 mm) | 72-Lead LFCSP (10 x 10 mm) | Footprint and thermal characteristics must match for PCB compatibility; identical packages allow the same land pattern. |
| Packaging / Delivery Form | Tray | Tape & Reel | Affects manufacturing handling and assembly line feed method; the reel version suits automated high-volume SMT production while the tray suits low-volume or prototyping. |
| Ordering Quantity per Package | 1 (individual tray unit) | Reel quantity (multiple units per reel) | Impacts procurement lot sizing and inventory management; the reel variant is ordered in larger quantities for production runs. |

Frequently asked questions
What is the difference between AD9142ABCPZ and AD9142ABCPZRL?
Both are the same AD9142A dual 16-bit 1600 MSPS TxDAC+ device in a 72-lead LFCSP package. The difference is packaging format: AD9142ABCPZ is supplied in trays, while AD9142ABCPZRL is supplied in tape-and-reel for automated assembly. Electrical and functional specifications are identical.
Are AD9142ABCPZ and AD9142ABCPZRL electrically and functionally interchangeable?
Yes. Both order codes refer to the same silicon and package (72-lead LFCSP, 10 mm × 10 mm), so they share identical datasheet specifications, pinout, and performance. The only distinction is the shipping medium (tray vs. tape-and-reel).
What are the key performance specifications of the AD9142A?
The AD9142A is a dual 16-bit DAC with a maximum update rate of 1600 MSPS, an on-chip 32-bit digital datapath with interpolation, and a serial LVDS interface. It operates from 1.8 V and 3.3 V supplies and is specified for the industrial temperature range of −40°C to +85°C.
Which package and pin count do AD9142ABCPZ and AD9142ABCPZRL use?
Both parts use a 72-lead LFCSP (lead frame chip scale package) with exposed pad, measuring 10 mm × 10 mm. The package and pinout are identical between the two order codes.
Why would a design choose the tape-and-reel version AD9142ABCPZRL over the tray version AD9142ABCPZ?
Tape-and-reel packaging (AD9142ABCPZRL) is intended for high-volume automated pick-and-place assembly lines, while trays (AD9142ABCPZ) suit low-volume, prototyping, or manual assembly. The choice affects handling and assembly workflow, not device performance.
Do AD9142ABCPZ and AD9142ABCPZRL share the same moisture sensitivity level and handling requirements?
Yes. Because both order codes use the identical 72-lead LFCSP package, they carry the same moisture sensitivity level and reflow handling requirements as specified in the manufacturer's datasheet and packaging information.
Can AD9142ABCPZ and AD9142ABCPZRL be used in the same PCB footprint?
Yes. Since both are the same device in the same 72-lead LFCSP package with identical pinout, they share the same PCB land pattern and footprint. Either order code can be placed on a board designed for the AD9142A LFCSP package.
