Replacement verdict
Compatible functional replacement candidate
The AD8264ACPZ and AD8264ACPZ-RL are functionally identical, differing only in packaging format: the AD8264ACPZ is supplied in trays, while the AD8264ACPZ-RL is supplied in tape-and-reel for automated assembly. Both share the same die, package, pinout, and electrical specifications, making them interchangeable for design and qualification purposes; selection should be driven solely by the assembly and inventory handling requirements of the production line.

Frequently asked questions
What is the difference between AD8264ACPZ and AD8264ACPZ-RL?
The AD8264ACPZ and AD8264ACPZ-RL are the same AD8264 quad-channel, low-noise, high-speed operational amplifier with a fixed gain of 2, offered in a 32-lead LFCSP (CP-32-2) package. The suffix difference refers to packaging format: AD8264ACPZ is supplied in standard tray or tube quantities, while AD8264ACPZ-RL denotes tape-and-reel packaging for automated assembly. Electrical performance and die are identical.
Are AD8264ACPZ and AD8264ACPZ-RL electrically and functionally interchangeable?
Yes. Both order codes refer to the same silicon device, the AD8264, in the same 32-lead LFCSP package. They share identical specifications including gain of 2, bandwidth, noise, supply range, and pinout. The only difference is the shipping container (tray/tube versus tape-and-reel), so they are interchangeable in the application circuit.
What package and pin configuration do AD8264ACPZ and AD8264ACPZ-RL use?
Both parts use the 32-lead LFCSP (CP-32-2) package with an exposed pad. The pinout is identical between the two order codes, with four independent op-amp channels, gain-setting resistors, and power supply pins arranged per the AD8264 datasheet. The exposed pad should be soldered to the PCB ground plane for thermal and electrical performance.
What are the key specifications of the AD8264 that apply to both order codes?
The AD8264 is a quad, low-noise, high-speed amplifier with fixed gain of 2. Verified datasheet parameters include a -3 dB bandwidth of approximately 240 MHz (G = 2), slew rate of about 700 V/µs, input voltage noise of approximately 2.7 nV/√Hz, and operation on ±5 V or single 5 V supplies. It is specified for the industrial temperature range of -40°C to +85°C. These specifications apply equally to AD8264ACPZ and AD8264ACPZ-RL.
Why would a designer choose the tape-and-reel version AD8264ACPZ-RL over AD8264ACPZ?
AD8264ACPZ-RL is supplied in tape-and-reel format, which is compatible with automated pick-and-place assembly lines and is preferred for high-volume production. AD8264ACPZ in tray or tube format is typically used for prototyping, low-volume builds, or manual assembly. The choice is purely a manufacturing/logistics decision, not an electrical one.
Do AD8264ACPZ and AD8264ACPZ-RL have the same moisture sensitivity and handling requirements?
Yes. Because both order codes contain the identical 32-lead LFCSP package, they share the same moisture sensitivity level (MSL) and reflow profile as specified by Analog Devices for the AD8264 in the CP-32-2 package. Both require the same bake, storage, and reflow precautions per the manufacturer's datasheet and JEDEC standards.
Can AD8264ACPZ and AD8264ACPZ-RL be used in the same PCB footprint?
Yes. Since both are the same AD8264 die in the same 32-lead LFCSP (CP-32-2) package, the PCB land pattern, pinout, and exposed pad dimensions are identical. A board designed for one order code will accept the other without layout changes.
Where can verified ordering and packaging information for AD8264ACPZ and AD8264ACPZ-RL be found?
Authoritative ordering information, including package type, temperature range, and packaging format for each order code, is published in the Analog Devices AD8264 datasheet ordering guide and on distributor sites such as DigiKey and Mouser. Designers should confirm the current order code and packaging designation against the manufacturer's official documentation before production release.
