Replacement verdict
Compatible functional replacement candidate
The AD9142ABCPZ and AD9142BCPZRL are functionally equivalent dual 16-bit 1.6 GSPS DACs sharing identical die, package, and pinout; the only distinction is the delivery format, with the BCPZRL supplied as tape-and-reel product. Both parts are interchangeable for design and production use, and the reel variant is a valid drop-in substitute for the tray variant.

Key electrical and mechanical differences between the two devices
| Parameter | AD9142ABCPZ | AD9142BCPZRL | 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 enables I/Q signal generation; matching channel count ensures functional interchangeability. |
| Maximum Update Rate | 1600 MSPS | 1600 MSPS | Sets the maximum sample rate for wideband signal synthesis; identical rates mean the same bandwidth capability. |
| Output Interface | JESD204B | JESD204B | Defines the digital input protocol; matching serial interface ensures compatibility with the same FPGA/ASIC host. |
| Supply Voltage | 1.8 V / 3.3 V | 1.8 V / 3.3 V | Determines power rail requirements; identical rails allow drop-in replacement without board redesign. |
| Package / Case | 72-Lead LFCSP (10x10 mm) | 72-Lead LFCSP (10x10 mm) | Footprint and thermal characteristics must match for physical substitutability on the PCB. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Ensures the device meets the environmental requirements of the target application; identical ranges confirm equivalent ruggedness. |
| Packaging / Ordering Format | Tray | Tape & Reel | Affects manufacturing handling and assembly line compatibility; the reel version suits high-volume automated placement while the tray suits prototyping. |

Frequently asked questions
What are the key differences between AD9142ABCPZ and AD9142BCPZRL?
Both parts are the same AD9142A dual 16-bit 1.6 GSPS DAC in a 72-lead LFCSP package. The AD9142ABCPZ is the standard tray packaging option, while AD9142BCPZRL is the tape-and-reel packaging variant. The "RL" suffix denotes reel packaging; the "A" in AD9142ABCPZ refers to the device revision grade. Electrical performance and die are identical; only the packaging and ordering format differ.
Are AD9142ABCPZ and AD9142BCPZRL electrically and functionally interchangeable?
Yes. Both are the AD9142A dual-channel 16-bit DAC with the same die, pinout, and specified performance. They differ only in packaging format (tray vs. tape-and-reel), so they are functionally interchangeable in a design, provided the board assembly process accommodates the respective packaging.
What is the difference between the "A" in AD9142ABCPZ and the base AD9142BCPZRL part number?
The "A" designates the AD9142A revision of the device, which is the current production grade. The AD9142BCPZRL is also an AD9142A device; the "RL" suffix indicates tape-and-reel packaging. Both share the same datasheet specifications for the AD9142A.
What package do AD9142ABCPZ and AD9142BCPZRL use?
Both devices are supplied in a 72-lead LFCSP (lead frame chip scale package). The package body and pinout are identical between the two ordering options.
Which part should be selected for high-volume automated assembly?
AD9142BCPZRL is the tape-and-reel option, which is generally preferred for high-volume automated pick-and-place assembly lines. AD9142ABCPZ in tray format is typically used for prototyping, low-volume runs, or manual assembly.
Do AD9142ABCPZ and AD9142BCPZRL have the same resolution and sample rate?
Yes. Both are dual 16-bit DACs with a maximum update rate of 1.6 GSPS, as specified in the AD9142A datasheet. Resolution and sample rate are identical across both ordering variants.
Can AD9142ABCPZ and AD9142BCPZRL be used in the same PCB footprint?
Yes. Because both are the same 72-lead LFCSP device with identical pinout, they share the same PCB land pattern. No layout change is required when switching between the tray and tape-and-reel ordering options.
