X9C103PIZ

Overview

The X9C103PIZ is a single-channel digital potentiometer from the X9C10 series, manufactured by Renesas Electronics. It features a 10 kΩ resistance value with 100 tap positions and linear taper. The device utilizes non-volatile memory to retain wiper settings upon power loss. It operates on a 5 V supply voltage with a maximum current consumption of 750 µA. The component supports a 3-wire serial interface for control and is housed in an 8-pin PDIP package. It functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Non-volatile EEPROM storage retains wiper position after power cycle
• 100-tap resolution with linear resistance taper
• Simple 3-wire serial interface (INC, U/D, CS)
• Low power consumption of 750 µA at 5 V

Applications

• Voltage divider circuits requiring programmable ratios
• Gain control in audio or signal processing chains
• Calibration adjustments in test equipment
• System configuration via microcontroller interfaces

Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status via official datasheets. Check for End-of-Life (EOL) notices or Production Change Notices (PCN) affecting availability. Ensure packaging type matches design requirements, as tube quantities vary. Validate lead times due to potential supply chain constraints for legacy components.

Selection Notes

Select this model for applications requiring persistent resistance settings without battery backup. Compare against X9C103SZT1 if surface mount SOIC packaging is preferred over through-hole PDIP. Ensure the 20% tolerance and 300 ppm/°C temperature coefficient meet circuit accuracy requirements. Verify that the 1 mA max current limit is sufficient for the intended load, as high currents may damage the internal MOSFET switches.

Part Context

This part belongs to the X9C10 family of CMOS digital potentiometers, which includes variants like X9C102, X9C104, and X9C503. These devices share similar control logic but differ in resistance values and memory types. The PIZ suffix specifically denotes the PDIP-8 package variant, distinguishing it from SMD options like SZ or SIZ.

Replacement Considerations

Direct pin-compatible replacements include X9C103SZT1 (SOIC-8 package) and X9C103SIZ (SOIC-8 package). Verify that the alternative package fits the PCB footprint. Ensure the replacement maintains the same 10 kΩ resistance, 100 taps, and non-volatile memory characteristics.
