Replacement verdict
Compatible functional replacement candidate
The AD9200ARSZRL is a lead-free, RoHS-compliant reel-packaged variant of the AD9200ARS and is functionally interchangeable in the same 28-lead SSOP footprint, with identical 10-bit resolution, 20 MSPS sampling rate, and 2.7 V to 5.5 V supply range. The only meaningful distinction is packaging and environmental compliance, so the ARSZRL version can serve as a direct drop-in substitute where RoHS compliance and tape-and-reel assembly are required.

Key electrical and mechanical differences between the two devices
| Parameter | AD9200ARSZRL | AD9200ARS | Why it matters |
|---|---|---|---|
| Package / Case | 28-SSOP (0.209", 5.30mm Width) | 28-SSOP (0.209", 5.30mm Width) | Both use the same SSOP-28 footprint, so board layout is interchangeable; the difference lies in packaging format (tape-and-reel vs tube). |
| Packaging | Tape & Reel (RL) | Tube | Packaging affects assembly line handling and minimum order quantities; tape-and-reel suits automated pick-and-place, tube suits low-volume or prototyping. |
| Resolution | 10 bits | 10 bits | Bit depth determines quantization accuracy and dynamic range; identical resolution means equivalent signal fidelity. |
| Sampling Rate | 20 MSPS | 20 MSPS | Maximum sample rate defines the input bandwidth the ADC can digitize; matching rates ensures identical throughput capability. |
| Supply Voltage | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Operating supply range determines compatibility with system power rails; identical ranges allow drop-in substitution. |
| Input Type | Differential / Single-ended | Differential / Single-ended | Input configuration affects analog front-end design; matching flexibility means the same driver circuit can be reused. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Temperature range defines environmental robustness; identical ratings mean equivalent reliability in the same application conditions. |
| RoHS / Lead-Free Status | RoHS Compliant (Z suffix) | Non-RoHS (leaded) | RoHS compliance affects regulatory acceptance and solder process compatibility; the Z-suffix part is lead-free while the non-Z part contains lead. |
| Power Consumption | ~100 mW (typical) | ~100 mW (typical) | Power draw impacts thermal design and battery life; identical consumption means no change to power budget. |

Frequently asked questions
What is the difference between AD9200ARSZRL and AD9200ARS?
Both are the same AD9200 10-bit, 20 MSPS analog-to-digital converter from Analog Devices in a 28-lead SSOP package. The AD9200ARSZRL is the RoHS-compliant tape-and-reel version (Z suffix denotes lead-free/RoHS compliance, RL denotes reel packaging), while the AD9200ARS is the non-RoHS tube-packaged version. The AD9200ARSZRL is the currently active ordering code; the AD9200ARS is the legacy non-RoHS variant.
Are AD9200ARSZRL and AD9200ARS electrically and functionally interchangeable?
Yes. Both parts share the same die, pinout, and specified performance for the AD9200 (10-bit resolution, 20 MSPS maximum sampling rate, 2.7 V to 5.5 V supply range, 28-lead SSOP). The only differences are RoHS compliance and packaging format, so they are functionally interchangeable in the same PCB footprint.
What are the key specifications of the AD9200?
The AD9200 is a 10-bit monolithic CMOS ADC with a 20 MSPS maximum conversion rate, on-chip sample-and-hold, and an internal voltage reference. It operates from a single 2.7 V to 5.5 V supply, offers a differential or single-ended analog input, and provides a power-down mode. It is specified for 10-bit accuracy with typical SNR around 59 dB and is housed in a 28-lead SSOP.
Does the AD9200ARSZRL meet RoHS requirements while the AD9200ARS does not?
Yes. The "Z" in AD9200ARSZRL designates the RoHS-compliant, lead-free (Pb-free) package finish per Analog Devices ordering conventions. The AD9200ARS is the older non-RoHS ordering code and should not be used in new designs requiring RoHS compliance.
What packaging format does each part use?
The AD9200ARSZRL is supplied in tape-and-reel format (the "RL" suffix), which is suited to automated high-volume SMT assembly. The AD9200ARS is supplied in standard tube/rail packaging. Both use the identical 28-lead SSOP body.
Can I substitute AD9200ARSZRL for AD9200ARS in an existing design?
Yes, provided the design does not have a restriction against RoHS-compliant lead-free finishes. The electrical specifications, pinout, and package footprint are identical, so the AD9200ARSZRL can directly replace the AD9200ARS. Verify solder profile compatibility with the Pb-free finish if the existing process was qualified only for the non-RoHS part.
Which part should be selected for a new design?
The AD9200ARSZRL should be selected for new designs because it is the RoHS-compliant, actively supported ordering code in tape-and-reel packaging. The AD9200ARS non-RoHS variant is a legacy code and is not recommended for new RoHS-required designs.
