Replacement verdict
Compatible functional replacement candidate
The AD8564ARZ-REEL7 and AD8564AR are functionally equivalent quad comparators sharing the same core die, pinout, and electrical specifications; the only meaningful distinction is packaging format, with the REEL7 variant supplied in tape-and-reel for automated assembly while the AD8564AR is provided in tube form. Designers can treat them as interchangeable in circuit design, with the choice driven by manufacturing and inventory considerations rather than performance.

Key electrical and mechanical differences between the two devices
| Parameter | AD8564ARZ-REEL7 | AD8564AR | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures consistent design, documentation, and quality standards. |
| Amplifier Type | Comparator | Comparator | Both are comparators, so they serve the same core signal-comparison function. |
| Number of Channels | 4 | 4 | Channel count must match for pin-compatible and functional substitution in multi-channel designs. |
| Package / Case | 14-SOIC (0.154", 3.90mm Width) | 14-SOIC (0.154", 3.90mm Width) | Identical package footprint allows drop-in replacement on the same PCB layout. |
| Mounting Type | Surface Mount | Surface Mount | Same mounting style ensures compatibility with the existing assembly process. |
| Supply Voltage Range | ±4.5V to ±16.5V (or 9V to 33V single supply) | ±4.5V to ±16.5V (or 9V to 33V single supply) | Matching supply range confirms the part works in the same power environment. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Identical temperature ratings ensure equivalent reliability across the application's thermal envelope. |
| Packaging / Ordering Format | Tape & Reel (REEL7) | Tube / Bulk | Different packaging affects automated assembly handling and minimum order quantities, though the die is the same. |
| Lead-Free / RoHS Status | RoHS Compliant, lead-free (Z suffix) | Non-RoHS / contains lead (no Z suffix) | RoHS compliance is critical for regulatory and environmental requirements in many markets. |

Frequently asked questions
What is the difference between AD8564ARZ-REEL7 and AD8564AR?
Both are quad 16 ns single-supply comparators from Analog Devices in an 16-lead SOIC package. The AD8564ARZ-REEL7 is the RoHS-compliant (Z) version supplied on a 7-inch tape-and-reel for automated assembly, while the AD8564AR is the non-RoHS tube/rail version. The electrical specifications are the same; the differences are packaging, RoHS status, and ordering format.
Are the AD8564ARZ-REEL7 and AD8564AR electrically identical?
Yes. Both devices share the same datasheet specifications: quad comparators, 16 ns propagation delay, single-supply operation from 2.7 V to 5.5 V, and the same pinout in the 16-lead SOIC package. The "Z" suffix denotes RoHS compliance and the "REEL7" suffix denotes tape-and-reel packaging; neither affects the electrical performance.
Can AD8564AR be used as a drop-in replacement for AD8564ARZ-REEL7?
Functionally and pinout-wise, yes, since both are the same die in the same 16-lead SOIC package. However, AD8564AR is not RoHS-compliant, so it cannot be substituted in designs or production lines that require RoHS compliance. Verify the RoHS requirement of your assembly before substituting.
What is the difference between the "REEL7" and non-reel ordering options?
REEL7 indicates the device is supplied on a 7-inch tape-and-reel carrier, typically 750 or 1,000 pieces per reel depending on the manufacturer's standard, suitable for automated pick-and-place assembly. The non-reel AD8564AR is supplied in tube/rail packaging intended for manual handling or low-volume prototyping.
What are the key specifications of the AD8564?
The AD8564 is a quad comparator with 16 ns propagation delay, single-supply operation from 2.7 V to 5.5 V, low power consumption, and rail-to-rail output swing. It is offered in a 16-lead SOIC package and is specified over the industrial temperature range. Consult the Analog Devices datasheet for complete guaranteed limits.
Does the "Z" suffix affect the operating temperature range or performance?
No. The "Z" suffix in AD8564ARZ designates RoHS compliance (lead-free, halogen-free molding compound) and does not change the specified operating temperature range or electrical performance relative to the non-Z version.
Which version should be selected for a new RoHS-compliant design?
For new designs requiring RoHS compliance, select AD8564ARZ-REEL7, which is the RoHS-compliant tape-and-reel option. The non-RoHS AD8564AR should be reserved for legacy or non-RoHS-restricted applications.
