Replacement verdict
Compatible functional replacement candidate
The AD5263BRUZ50 and AD5263BRU200 are functionally compatible digital potentiometers from the same AD5263 family, sharing identical package, interface, channel count, and operating temperature range. The primary distinction is end-to-end resistance, which directly affects the wiper resistance ratio and current handling in the target circuit. The AD5263BRU200 can substitute for the AD5263BRUZ50 only when the application tolerates the higher nominal resistance and the resulting changes in signal attenuation, gain setting, or bias current. Design validation is recommended before committing to a drop-in replacement.

Key electrical and mechanical differences between the two devices
| Parameter | AD5263BRUZ50 | AD5263BRU200 | Why it matters |
|---|---|---|---|
| End-to-End Resistance | 50 kΩ | 200 kΩ | Determines the nominal resistance range of the digital potentiometer and directly affects the current through and voltage across the device in a given circuit. |
| Number of Positions | 256 | 256 | Defines the wiper resolution; identical resolution means both parts offer the same number of adjustable steps for a given end-to-end resistance. |
| Number of Channels | 4 | 4 | Indicates how many independent potentiometer channels are integrated, which affects board space and channel count in multi-channel designs. |
| Interface Type | SPI | SPI | Determines the digital communication protocol required by the host controller for programming the wiper settings. |
| Supply Voltage Range | 4.5 V to 16.5 V (or ±2.25 V to ±8.25 V) | 4.5 V to 16.5 V (or ±2.25 V to ±8.25 V) | Defines the allowable operating voltage, which must match the system power rails for proper operation and signal swing. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Specifies the ambient temperature range over which the device is guaranteed to meet its electrical specifications. |
| Package / Mounting Type | 16-Lead TSSOP, Surface Mount | 16-Lead TSSOP, Surface Mount | Ensures physical and footprint compatibility for drop-in replacement on an existing PCB layout. |
| Wiper Resistance (Typical) | 60 Ω | 60 Ω | Affects the minimum achievable resistance and the accuracy of the potentiometer, especially at low resistance settings. |
| Resistance Tolerance | ±30 % | ±30 % | Indicates the part-to-part variation in end-to-end resistance, which impacts absolute accuracy in ratiometric and absolute resistance applications. |

Frequently asked questions
What is the main difference between the AD5263BRUZ50 and AD5263BRU200?
The primary difference is the end-to-end resistance value: the AD5263BRUZ50 has a 50 kΩ nominal resistance, while the AD5263BRU200 has a 200 kΩ nominal resistance. Both are quad-channel, 256-position digital potentiometers from Analog Devices in a 14-lead TSSOP package.
Are the AD5263BRUZ50 and AD5263BRU200 pin-compatible?
Yes. Both devices are offered in the same 14-lead TSSOP (RU-14) package and share the same pinout, so they are pin-compatible. The difference is the internal resistor array value, not the package or pin functions.
Can the AD5263BRUZ50 and AD5263BRU200 be used interchangeably in a design?
Not without verifying the circuit requirements. Because the end-to-end resistance differs by a factor of four, the wiper resistance, bandwidth, and loading effects on the surrounding circuit will differ. The replacement is only valid if the design tolerates the new resistance value and the resulting changes in gain, attenuation, or timing.
What is the resolution and number of positions for both the AD5263BRUZ50 and AD5263BRU200?
Both devices provide 256 positions (8-bit resolution) per channel and include four independent digital potentiometer channels in one package.
What supply voltage and interface do the AD5263BRUZ50 and AD5263BRU200 support?
Both parts operate from a single 2.7 V to 5.5 V supply or dual ±2.7 V supplies, and they use a 3-wire SPI-compatible serial interface for programming the wiper positions.
Do the AD5263BRUZ50 and AD5263BRU200 have the same temperature coefficient and tolerance?
No. The resistor tolerance and temperature coefficient are specified separately for each resistance value in the Analog Devices datasheet. The 50 kΩ and 200 kΩ versions have different ratiometric and end-to-end specifications, so the datasheet for the specific part number must be consulted.
Which applications typically favor the AD5263BRUZ50 versus the AD5263BRU200?
The AD5263BRUZ50 is often chosen when lower resistance and higher current handling are needed, while the AD5263BRU200 is used when higher resistance is required to reduce loading in high-impedance signal paths. The selection depends on the required gain, filter, or bias network values in the target circuit.
