Replacement verdict
Compatible functional replacement candidate
The AD8041ARZ and AD8041AR-REEL7 are the same AD8041 operational amplifier die offered in identical 8-lead SOIC packages, differing only in packaging format (tube vs. tape-and-reel). Both share the same electrical specifications, pinout, and temperature range, making them functionally interchangeable for design and qualification purposes; the choice between them is driven by assembly and inventory handling requirements rather than performance.

Key electrical and mechanical differences between the two devices
| Parameter | AD8041ARZ | AD8041AR-REEL7 | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback | Voltage Feedback | Both are voltage-feedback op amps, so the feedback topology and gain-setting behavior are interchangeable. |
| Number of Circuits | 1 | 1 | Single-channel configuration must match for direct board-level substitution. |
| -3dB Bandwidth | 160 MHz | 160 MHz | Bandwidth determines the maximum signal frequency the amplifier can handle with acceptable gain roll-off. |
| Slew Rate | 160 V/µs | 160 V/µs | Slew rate limits large-signal response and distortion at high frequencies; matching values ensure equivalent dynamic performance. |
| Input Offset Voltage | 1 mV | 1 mV | Offset voltage affects DC accuracy; identical values mean no recalibration is needed when swapping parts. |
| Supply Voltage Range | 3 V to 12 V | 3 V to 12 V | The operating supply window must match to ensure the part works in the same rail configuration. |
| Supply Current | 6.8 mA | 6.8 mA | Quiescent current impacts power budget and thermal design; matching values preserve the same power profile. |
| Package / Case | 8-SOIC | 8-SOIC | Identical package and footprint allow drop-in replacement on the same PCB land pattern. |
| Packaging | Tube | Tape & Reel | Packaging differs for automated assembly versus manual handling, but the electrical part is the same. |

Frequently asked questions
What are the key differences between AD8041ARZ and AD8041AR-REEL7?
Both parts are the same AD8041 operational amplifier die in an 8-lead SOIC package. The AD8041ARZ is supplied in tube/tray packaging and carries the RoHS-compliant "Z" suffix, while AD8041AR-REEL7 is the same device supplied on a 7-inch tape-and-reel for automated assembly and does not carry the RoHS "Z" designation.
Are AD8041ARZ and AD8041AR-REEL7 electrically and functionally identical?
Yes. Both are the AD8041 rail-to-rail output, 160 MHz, low-power voltage feedback operational amplifier with the same specified AC and DC performance. The only differences are packaging format and RoHS compliance marking, not the silicon or electrical specifications.
Can AD8041AR-REEL7 be used as a drop-in replacement for AD8041ARZ?
Electrically and functionally yes, since both are the same AD8041 device in an 8-lead SOIC package with identical pinout. However, the AD8041AR-REEL7 is a non-RoHS variant, so it should not be substituted where RoHS compliance is a requirement; verify the assembly's compliance obligations before substituting.
What package and pinout do AD8041ARZ and AD8041AR-REEL7 use?
Both devices are offered in an 8-lead SOIC (Small Outline Integrated Circuit) package with the standard AD8041 pinout: 1 = NC, 2 = -IN, 3 = +IN, 4 = -VS, 5 = NC, 6 = OUT, 7 = +VS, 8 = NC. The package and pin assignment are identical between the two orderable part numbers.
Why would a design choose AD8041AR-REEL7 instead of AD8041ARZ?
AD8041AR-REEL7 is supplied on 7-inch tape-and-reel, which suits high-volume automated pick-and-place assembly lines. AD8041ARZ in tube/tray form is typically chosen for prototyping, low-volume runs, or where RoHS compliance is mandatory.
Do AD8041ARZ and AD8041AR-REEL7 differ in RoHS status?
Yes. The "Z" suffix in AD8041ARZ denotes the RoHS-compliant version of the AD8041 in the 8-lead SOIC package. AD8041AR-REEL7 is the non-RoHS tape-and-reel orderable variant. Designers with RoHS obligations should select the Z-suffixed part.
What are the key specifications shared by AD8041ARZ and AD8041AR-REEL7?
Both are single AD8041 voltage feedback op amps with 160 MHz -3 dB bandwidth, 160 V/µs slew rate, rail-to-rail output, and operation on ±5 V or single 5 V supplies. They are specified for the industrial temperature range and are intended for video, ADC driving, and general-purpose signal conditioning applications.
How should inventory and BOM records distinguish AD8041ARZ from AD8041AR-REEL7?
Treat them as separate orderable part numbers because packaging (tube vs 7-inch reel) and RoHS status differ. Maintain distinct BOM line items and inventory records so that automated assembly lines receive the reeled variant and RoHS-controlled builds receive the Z-suffixed variant.
