Replacement verdict
Compatible functional replacement candidate
The AD75019JPZ and AD75019JP are functionally equivalent crosspoint switch devices sharing the same core architecture, channel count, and package footprint, with the JPZ suffix denoting a lead-free/RoHS-compliant package variant of the same silicon. The primary distinction lies in package material compliance and environmental qualification rather than electrical function, making the JPZ a viable functional replacement for the JP in most designs, subject to confirming RoHS requirements and solder profile compatibility.

Key electrical and mechanical differences between the two devices
| Parameter | AD75019JPZ | AD75019JP | Why it matters |
|---|---|---|---|
| Switch Configuration | 16 x 16 crosspoint array | 16 x 16 crosspoint array | Defines the matrix size and signal routing capability; identical configuration means the same switching topology is available. |
| Number of Switches | 256 | 256 | Determines how many independent crosspoint connections can be made; matching counts ensure equivalent routing capacity. |
| On-Resistance (typ) | 50 Ohm | 50 Ohm | Affects signal attenuation and insertion loss; identical on-resistance supports equivalent analog signal integrity. |
| Supply Voltage (dual) | ±10 V to ±15 V | ±10 V to ±15 V | Sets the analog signal range and compatibility with system power rails; matching ranges allow drop-in substitution. |
| Package / Mounting | 28-Pin PLCC (Surface Mount) | 28-Pin PLCC (Surface Mount) | Determines PCB footprint and assembly process; identical package allows physical interchangeability. |
| RoHS Compliance | RoHS Compliant (Pb-free) | Non-RoHS (contains lead) | Affects regulatory compliance and solder process; the Z suffix denotes lead-free, which matters for environmental and manufacturing requirements. |
| Operating Temperature Range | 0°C to +70°C | 0°C to +70°C | Defines the environmental envelope for reliable operation; matching ranges ensure equivalent thermal performance. |
| Control Interface | Serial (SPI-compatible) | Serial (SPI-compatible) | Determines how the host configures the switch matrix; identical interface allows reuse of existing firmware and drivers. |

Frequently asked questions
What is the difference between AD75019JPZ and AD75019JP?
The AD75019JPZ and AD75019JP are functionally identical 16 x 16 crosspoint switch arrays. The primary difference is the package and lead finish: the AD75019JPZ is the RoHS-compliant version supplied in a 44-lead PLCC package with a lead-free (matte tin) finish, while the AD75019JP is the non-RoHS version of the same device in the same 44-lead PLCC package with a tin-lead finish.
Are AD75019JPZ and AD75019JP electrically interchangeable?
Yes. Both devices share the same electrical specifications, including the 16 x 16 crosspoint switch matrix, on-resistance, supply voltage range, and serial control interface. The only difference is the package finish (RoHS-compliant vs. non-RoHS), so they are electrically interchangeable in the same circuit.
Can AD75019JPZ be used as a drop-in replacement for AD75019JP?
Yes, in most cases. Both parts use the same 44-lead PLCC package with identical pinout and footprint, so the AD75019JPZ can be used as a drop-in replacement for the AD75019JP. The substitution is appropriate when RoHS compliance is required or acceptable; verify the assembly process is compatible with the lead-free finish.
What is the function of the AD75019 crosspoint switch?
The AD75019 is a 16 x 16 crosspoint switch array that allows any of 16 inputs to be connected to any of 16 outputs. It is controlled through a serial interface and is used for signal routing in applications such as test equipment, instrumentation, and communication systems.
What package do AD75019JPZ and AD75019JP use?
Both devices are supplied in a 44-lead PLCC (Plastic Leaded Chip Carrier) package. The package dimensions, pin count, and pinout are identical between the two versions.
Does the RoHS status of AD75019JPZ affect its performance?
No. The RoHS-compliant lead-free finish of the AD75019JPZ does not change the device's electrical performance or functional specifications compared with the non-RoHS AD75019JP. The difference is limited to the package finish and environmental compliance.
Which version should be selected for a new design?
For new designs, the AD75019JPZ is generally preferred because it is RoHS-compliant and supports lead-free assembly processes. The AD75019JP may still be used where non-RoHS tin-lead assembly is required or where existing inventory is being consumed.
