Replacement verdict
Compatible functional replacement candidate
The AD9826KRSZRL is a tape-and-reel packaged variant of the AD9826KRS and shares the same core analog front-end architecture, channel count, supply requirements, and temperature range. The two parts are functionally interchangeable in the same 28-lead SSOP footprint, with the primary distinction being packaging format and RoHS compliance status. Designers should confirm reel quantity and moisture sensitivity handling requirements before substituting in volume production.

Key electrical and mechanical differences between the two devices
| Parameter | AD9826KRSZRL | AD9826KRS | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures consistent design, documentation, and support for both parts. |
| Function / Type | Complete 16-bit imaging signal processor (analog front end) with 3-channel architecture | Complete 16-bit imaging signal processor (analog front end) with 3-channel architecture | Identical core function confirms the parts are functionally interchangeable in imaging/CCD signal-chain designs. |
| Resolution | 16-bit ADC | 16-bit ADC | Bit depth directly determines the dynamic range and precision of the digitized image signal. |
| Number of Channels | 3 channels (RGB / 3-channel CCD) | 3 channels (RGB / 3-channel CCD) | Channel count must match the sensor architecture for correct color or multi-channel acquisition. |
| Package / Case | 28-lead SSOP | 28-lead SSOP | Same package footprint allows drop-in board replacement without layout changes. |
| Mounting Type | Surface Mount | Surface Mount | Mounting style must match the assembly process and PCB design. |
| Supply Voltage | 3.3 V analog and digital supply (3.0 V to 3.6 V range) | 3.3 V analog and digital supply (3.0 V to 3.6 V range) | Supply voltage compatibility is essential for direct substitution without regulator changes. |
| Operating Temperature Range | 0°C to +70°C (commercial) | 0°C to +70°C (commercial) | Temperature rating must meet the application environment for reliable operation. |
| Packaging / Ordering Suffix | Tape and reel (RL suffix), RoHS-compliant (Z) | Tube / bulk, non-RoHS (no Z suffix) | Packaging form affects automated assembly handling, and the RoHS status affects regulatory compliance for the finished product. |
| RoHS Compliance | RoHS compliant (Pb-free) | Non-RoHS (contains lead) | RoHS status determines whether the part can be used in products sold into regulated markets requiring lead-free compliance. |

Frequently asked questions
What is the difference between AD9826KRSZRL and AD9826KRS?
Both are the same AD9826 complete analog front-end (AFE) for CCD/CIS imaging applications from Analog Devices. The AD9826KRS is supplied in a 28-lead SSOP package in tube form, while the AD9826KRSZRL is the RoHS-compliant version supplied in tape-and-reel packaging for automated assembly. The "Z" denotes RoHS compliance and "RL" denotes tape-and-reel.
Are AD9826KRSZRL and AD9826KRS electrically and functionally interchangeable?
Yes. Both parts share the same AD9826 die, the same 28-lead SSOP pinout, and the same electrical specifications (16-bit, 15 MSPS AFE with three 8-bit programmable gain amplifiers and a 16-bit ADC). The only differences are RoHS compliance and packaging format, so they are functionally interchangeable in the same PCB footprint.
Is the AD9826KRSZRL RoHS compliant while the AD9826KRS is not?
Yes. The "Z" suffix in AD9826KRSZRL indicates RoHS compliance per Analog Devices' part numbering convention, whereas the AD9826KRS is the non-RoHS version. Designs requiring RoHS compliance should use the AD9826KRSZRL.
What package do AD9826KRSZRL and AD9826KRS use?
Both devices are offered in a 28-lead SSOP (Shrink Small Outline Package). The package body and pin count are identical, so the PCB land pattern is the same for both variants.
What are the key performance specifications of the AD9826?
The AD9826 is a 16-bit, 15 MSPS analog front-end with three independent 8-bit programmable gain amplifiers (PGA), a 16-bit ADC, correlated double sampling (CDS), and an internal voltage reference. It operates from a single 5 V analog supply with a 3 V digital supply and is intended for CCD/CIS line-scan and area-scan imaging systems.
Why would a designer choose the AD9826KRSZRL over the AD9826KRS?
The AD9826KRSZRL is preferred for RoHS-compliant products and for high-volume automated SMT assembly, since tape-and-reel packaging supports pick-and-place equipment. The AD9826KRS in tubes is typically used for prototyping or low-volume runs where RoHS is not required.
Can AD9826KRSZRL and AD9826KRS be mixed on the same assembly?
Yes, from an electrical and footprint standpoint they are identical, so either variant can be placed on the same PCB. However, mixing RoHS and non-RoHS parts on one assembly may affect the overall RoHS status of the finished product, so the choice should be governed by the product's compliance requirements.
