X9313WS Digital Potentiometer Equivalent & Substitute Parts

Part Overview

The X9313WS is a 10kΩ digital potentiometer manufactured by Renesas Electronics Corporation, featuring 32 taps with Up/Down (U/D, INC, CS) interface control. This component is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and production continuity. The part operates on 5V supply with non-volatile memory and linear taper configuration, suitable for precision analog signal adjustment applications in data acquisition systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9313WS is determined by strict alignment with the following critical parameters:

• Resistance Value: 10kΩ (exact match required)
• Number of Taps: 32 (exact match required)
• Interface Protocol: Up/Down (U/D, INC, CS) (exact match required)
• Memory Type: Non-Volatile (exact match required)
• Supply Voltage: 5V (exact match required)
• Package: 8-SOIC form factor (exact match required)
• Taper Configuration: Linear (exact match required)

Two active substitutes meet these criteria. The X9313WSZ is a direct form, fit, and function replacement with identical electrical specifications and improved RoHS3 compliance. The X9315WSZ is a parametric equivalent that maintains all critical interface and functional parameters but differs in wiper resistance specification (200Ω versus 40Ω typical), which does not affect substitutability for standard potentiometer applications.

Parameter Comparison

Engineering Selection Recommendations

X9313WSZ is the primary recommended substitute for direct replacement applications. This part maintains identical electrical and mechanical specifications to the X9313WS while offering active product status and ROHS3 compliance certification. The transition from RoHS non-compliant to ROHS3 compliant status eliminates regulatory constraints for new designs and production environments subject to environmental compliance requirements.

X9315WSZ serves as a secondary parametric equivalent option. All functional interface parameters, control protocols, and mechanical form factors remain identical to the X9313WS. The difference in typical wiper resistance (200Ω versus 40Ω) does not affect circuit compatibility or substitutability in standard potentiometer applications where wiper resistance is not a critical design parameter. This part also carries active product status and ROHS3 compliance.

Selection between X9313WSZ and X9315WSZ should be based on design-specific requirements regarding wiper resistance characteristics and component availability.

Frequently Asked Questions (FAQ)

Q: Can X9313WSZ be used as a direct replacement for X9313WS in existing designs?

A: Yes. The X9313WSZ is electrically and mechanically identical to the X9313WS across all specified parameters. Pin configuration, interface protocol, resistance value, tap count, supply voltage, and package dimensions are equivalent. The primary difference is product status (active versus obsolete) and improved RoHS compliance.

Q: What is the difference between X9313WSZ and X9315WSZ?

A: Both parts are functionally equivalent for potentiometer applications. The primary difference is wiper resistance: X9313WSZ has 40Ω typical wiper resistance, while X9315WSZ has 200Ω typical wiper resistance. Both maintain identical 10kΩ end-to-end resistance, 32-tap configuration, Up/Down interface, and 8-SOIC packaging. Selection depends on whether wiper resistance is a critical design parameter.

Q: Are both substitute parts available in the same packaging format?

A: Yes. Both X9313WSZ and X9315WSZ are supplied in Tube packaging and use the 8-SOIC (0.154", 3.90mm Width) package format, identical to the original X9313WS specification.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS3 compliance indicates adherence to environmental and material composition standards. It does not alter electrical performance, interface behavior, or functional characteristics. The compliance upgrade reflects manufacturing process improvements and regulatory alignment.

Q: Can these substitutes be used interchangeably in the same PCB design?

A: Yes. Both X9313WSZ and X9315WSZ share identical pin assignments, package dimensions, and interface protocols. PCB layouts and circuit designs require no modification for either substitute part.
