Replacement verdict
Compatible functional replacement candidate
The AD8113JSTZ is a lead-free, RoHS-compliant version of the AD8113JST and is functionally interchangeable in the same 100-lead LQFP package with identical pinout and electrical specifications. The only meaningful distinction is package finish and environmental compliance, so the JSTZ can serve as a direct replacement for the JST in new and existing designs where lead-free assembly is acceptable.

Key electrical and mechanical differences between the two devices
| Parameter | AD8113JSTZ | AD8113JST | Why it matters |
|---|---|---|---|
| Function | Audio/Video Crosspoint Switch (16 x 16) | Audio/Video Crosspoint Switch (16 x 16) | Both parts perform the same core switching function, so they are functionally interchangeable in the same socket. |
| Number of Channels | 16 x 16 matrix | 16 x 16 matrix | Matching matrix size ensures the same number of inputs and outputs can be routed without redesign. |
| Package / Case | 80-LQFP (ST-80) | 80-LQFP (ST-80) | Identical package and footprint allow drop-in replacement on an existing PCB. |
| Mounting Type | Surface Mount | Surface Mount | Same mounting style confirms physical compatibility with the board assembly process. |
| Operating Temperature Range | 0°C to +70°C | 0°C to +70°C | Matching temperature ratings ensure equivalent environmental performance in the application. |
| Supply Voltage (Dual) | ±5 V (typical) | ±5 V (typical) | Same supply requirement means the existing power design can be reused without modification. |
| RoHS / Lead-Free Status | RoHS compliant, lead-free | Non-RoHS, contains lead | The Z suffix denotes the lead-free/RoHS version; this affects regulatory compliance and solder process compatibility. |
| Part Number Suffix Meaning | Z = RoHS-compliant package | No Z = standard (leaded) package | The suffix difference is the primary distinction between the two parts and determines compliance and assembly requirements. |

Frequently asked questions
What is the difference between AD8113JSTZ and AD8113JST?
The AD8113JSTZ is the RoHS-compliant, lead-free (Pb-free) version of the AD8113JST. Both are functionally identical 16 × 16 audio/video crosspoint switches in a 100-lead LQFP package; the "Z" suffix denotes the lead-free/RoHS-compliant package variant per Analog Devices part numbering conventions.
Are AD8113JSTZ and AD8113JST electrically and functionally interchangeable?
Yes. Both devices share the same die, pinout, and specified performance for the 16 × 16 crosspoint switch function, including the same supply requirements and control interface. The only documented difference is the package finish (lead-free/RoHS-compliant for the Z version), so they are functionally interchangeable in designs that accept either finish.
What is the package and pin count for these devices?
Both AD8113JSTZ and AD8113JST are supplied in a 100-lead LQFP (low-profile quad flat package). The "JST" code in the part number designates the 100-lead LQFP package and the commercial temperature grade.
What are the key specifications of the AD8113 crosspoint switch?
The AD8113 is a 16 × 16 analog crosspoint switch with a −3 dB bandwidth of approximately 60 MHz, low crosstalk, and differential gain/phase suitable for composite video and audio routing. It operates from ±5 V or single +5 V supplies and is controlled via a serial (SPI-compatible) interface. Designers should confirm exact limits against the official Analog Devices datasheet for the specific grade.
Does the "Z" suffix affect RoHS compliance and soldering?
Yes. The AD8113JSTZ is the RoHS-compliant, lead-free variant, while the AD8113JST is the older leaded (non-RoHS) version. The Z version is intended for lead-free reflow soldering processes and RoHS-restricted markets; the non-Z version may not meet current RoHS requirements.
Can I substitute AD8113JSTZ for AD8113JST in an existing design?
In most cases yes, because the devices are functionally and pin-compatible. However, the substitution should be validated against the target design's soldering process, RoHS requirements, and the manufacturer's datasheet, since the package finish differs. Confirm availability and lifecycle status with Analog Devices or an authorized distributor before qualifying the change.
Which version should be selected for a new RoHS-compliant design?
The AD8113JSTZ should be selected for new designs requiring RoHS compliance and lead-free assembly. The AD8113JST (non-Z) is the legacy leaded variant and is generally not appropriate for new RoHS-restricted products.
