Overview
The X9C503SIZT1 is a single-channel digital potentiometer from the XDCP series, manufactured by Renesas Electronics. It features a total resistance of 50 kOhms with a linear taper and 100 tap points. The device operates on a 5 V supply voltage (4.5 V to 5.5 V range) with a typical current consumption of 1 mA. It utilizes a non-volatile memory type to retain wiper position data. The component supports a 3-wire serial interface for control and is housed in an 8-SOIC surface-mount package. It is rated for an industrial temperature range from -40°C to +85°C.
Feature Summary
- Non-volatile EEPROM storage retains wiper position after power loss
- 50 kOhms resistance value with 20% tolerance and 300 PPM/C temperature coefficient
- Single channel configuration with 100 discrete taps
- 3-Wire serial interface (CS, U/D, INC) for digital control
Applications
- Digitally controlled resistance trimming
- Signal processing parameter adjustment
- System calibration and gain control
Procurement Notes
Verify the specific suffix 'IZT1' against the manufacturer's datasheet to confirm the industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Ensure compatibility with standard SOIC-8 footprints during PCB layout. Cross-reference RoHS compliance status with the latest production notices.
Selection Notes
Select this model when a 50 kOhms digital potentiometer with non-volatile memory is required for industrial environments. Compare against the commercial grade X9C503SZ if the operating temperature range of 0°C to 70°C is sufficient. Verify that the 100-tap resolution meets the precision requirements of the application circuit.
Part Context
This part belongs to the X9C503 family of digitally controlled potentiometers. It shares functional similarities with the X9C103 but differs in resistance value (50k vs 10k). The 'I' suffix typically denotes the industrial temperature range, while 'Z' indicates lead-free/RoHS compliance, and 'T1' specifies the reel packaging quantity.
Replacement Considerations
Direct pin-compatible alternatives within the same family include the X9C503SZ for commercial temperature ranges. For different resistance values, consider the X9C103 or X9C104. Verify that any substitute maintains the 3-wire serial interface and non-volatile memory characteristics.
