X9C103PZ

Overview

The X9C103PZ is a single-channel digital potentiometer IC from the X9C10 series, manufactured by Renesas Electronics. It features a 10 kOhm resistance value with a linear taper and 100 tap positions for precise adjustment. The device utilizes non-volatile memory to retain wiper settings without power. It operates on a single 5 V supply with a maximum current consumption of 750 uA. The component supports a 3-wire serial interface and is housed in an 8-pin PDIP package designed for through-hole PCB mounting.

Feature Summary

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

Applications

• Volume control in audio equipment
• Gain adjustment in instrumentation circuits
• Voltage reference trimming
• System calibration requiring manual or remote adjustment

Procurement Notes

Verify component status as the X9C103PZ is listed as obsolete or end-of-life by the manufacturer. Check for available stock from authorized distributors or secondary market suppliers. Confirm RoHS compliance details via the official datasheet before procurement planning.

Selection Notes

Select this part for through-hole designs requiring non-volatile digital potentiometry. Ensure the circuit accommodates the 20% resistance tolerance and 300 PPM/C temperature coefficient. Verify that the 4.5 V to 5.5 V supply range matches the system voltage. Consider surface-mount alternatives like X9C103SZ if board space is constrained.

Part Context

This component belongs to the X9C10 family of CMOS EEPOT devices. It serves as a solid-state replacement for mechanical potentiometers in applications where size, reliability, and non-volatility are critical. The 'PZ' suffix indicates the PDIP-8 package variant.

Replacement Considerations

Direct pin-compatible replacements include other X9C103 variants such as X9C103SZ (SOIC-8) or X9C103SIZ (Industrial Temp SOIC-8). Verify package type compatibility when substituting.
