Replacement verdict
Compatible functional replacement candidate
The AD9144BCPZ and AD9144BCPZRL are functionally identical dual 16-bit 2.8 GSPS DACs in the same 88-lead LFCSP package, differing only in packing format (tray vs. tape-and-reel). The AD9144BCPZRL is a valid drop-in replacement for the AD9144BCPZ, with no electrical, thermal, or footprint differences affecting substitutability.

Key electrical and mechanical differences between the two devices
| Parameter | AD9144BCPZ | AD9144BCPZRL | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Determines the quantization accuracy of the DAC output; identical resolution means equivalent signal fidelity. |
| Number of DAC Channels | 2 | 2 | Dual-channel architecture is required for I/Q signal generation; both parts provide the same channel count. |
| Maximum Update Rate | 2.8 GSPS | 2.8 GSPS | Sets the maximum sample rate for wideband signal synthesis; identical rates ensure the same bandwidth capability. |
| Output Interface | JESD204B | JESD204B | Defines the digital input protocol and lane configuration; matching interfaces allow drop-in compatibility with the same FPGA/ASIC link. |
| Supply Voltage | 1.8 V to 3.3 V | 1.8 V to 3.3 V | Determines power rail requirements and level compatibility; identical ranges mean the same board 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 physical board compatibility; identical packages allow the same PCB land pattern. |
| Packaging / Delivery Form | Tray | Tape & Reel | Affects manufacturing handling and assembly line feed method; the RL suffix denotes reel packaging for automated pick-and-place, while the base part is tray-delivered. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Defines the environmental envelope for reliable operation; identical ranges ensure the same thermal design margins apply. |

Frequently asked questions
What is the difference between AD9144BCPZ and AD9144BCPZRL?
Both are the same AD9144 quad 16-bit 2.8 GSPS DAC in a 88-lead LFCSP package. The suffix difference is packaging form: AD9144BCPZ is the standard tray packaging, while AD9144BCPZRL is the tape-and-reel packaging option. The silicon, specifications, and temperature range are identical.
Are AD9144BCPZ and AD9144BCPZRL electrically and functionally identical?
Yes. Both part numbers refer to the same AD9144 device. The only difference is the shipping packaging (tray vs. tape-and-reel). Electrical parameters, pinout, and functional behavior are the same per the Analog Devices datasheet.
Can AD9144BCPZ and AD9144BCPZRL be used interchangeably in a design?
Yes, from a design perspective they are interchangeable because they are the same die in the same 88-lead LFCSP package. The choice between them is driven by manufacturing/procurement preferences (tray for low-volume or prototyping, tape-and-reel for automated SMT assembly lines).
Which package do AD9144BCPZ and AD9144BCPZRL use?
Both use the 88-lead LFCSP (lead frame chip scale package) with exposed pad, designated CP-88-4 in Analog Devices documentation. The package outline, pin count, and thermal pad are identical for both ordering codes.
What is the resolution and sample rate of the AD9144?
The AD9144 is a quad 16-bit digital-to-analog converter with a maximum update rate of 2.8 GSPS per DAC. It supports JESD204B serial input and is intended for wideband multi-channel transmit applications.
Why would a manufacturer offer both tray and tape-and-reel options for the same device?
Tray packaging (AD9144BCPZ) suits low-volume production, prototyping, and manual handling. Tape-and-reel (AD9144BCPZRL) supports high-volume automated pick-and-place assembly and is the standard format for SMT production lines. Offering both lets customers choose based on their manufacturing flow.
Do AD9144BCPZ and AD9144BCPZRL differ in price or availability?
Pricing and stock levels can differ between the two ordering codes because they are distinct distributor line items, but the underlying device is the same. Buyers should verify current pricing and availability with authorized distributors such as DigiKey, Mouser, or Analog Devices directly, as these vary over time.
