X9317WS8I Digital Potentiometer 10kΩ Equivalent & Substitute Parts

Part Overview

The X9317WS8I is a digital potentiometer manufactured by Renesas Electronics Corporation, featuring 10kΩ resistance with 100 taps and Up/Down (U/D, INC, CS) interface control. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part operates across -40°C to 85°C with 5V supply voltage and non-volatile memory configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9317WS8I is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 10kΩ
• Number of taps: 100
• Interface type: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Package: 8-SOIC
• Operating temperature range: -40°C to 85°C

Direct Equivalents maintain all primary parameters with identical electrical and mechanical specifications. These parts differ only in packaging format or product status.

Parametric Equivalents maintain all primary substitution criteria but may differ in secondary parameters such as wiper resistance or temperature coefficient, which do not affect core functionality within the specified operating range.

Similar Parts share the same package, interface, and tap configuration but differ in resistance value or supply voltage range. These require circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Choice): X9317WS8IZ is the direct equivalent of X9317WS8I, maintaining identical electrical specifications with active product status and ROHS3 compliance. This part is available in tube packaging and represents the optimal replacement for obsolete X9317WS8I applications.

Parametric Equivalents (Secondary Choices): X9318WS8IZ and X9C103SIZ are parametric equivalents with active status and ROHS3 compliance. Both maintain 10kΩ resistance, 100 taps, and identical interface configuration. The primary difference is wiper resistance (40Ω typical versus 200Ω), which does not affect substitution eligibility for standard potentiometer applications. Both are available in tube packaging.

Alternative Manufacturer Options: DS1804Z-010+ and DS1804Z-010+T&R (Analog Devices Inc./Maxim Integrated) provide 10kΩ, 100-tap digital potentiometer functionality with active product status and ROHS3 compliance. These parts support extended supply voltage range (2.7V ~ 5.5V) and are suitable for applications requiring broader voltage compatibility. Temperature coefficient is 750ppm/°C compared to 300ppm/°C for Renesas parts. Available in tube or cut tape & Digi-Reel packaging.

Not Recommended: CAT5113VI-01-GT3 (onsemi) features 1kΩ resistance instead of 10kΩ and is obsolete. This part is suitable only for applications specifically requiring 1kΩ potentiometer function and is not a direct substitute for 10kΩ designs.

Frequently Asked Questions (FAQ)

Q: Can X9317WS8IZ directly replace X9317WS8I without circuit modifications? A: Yes. X9317WS8IZ is a direct equivalent with identical electrical and mechanical specifications. The only differences are active product status and ROHS3 compliance, which represent improvements over the obsolete original part.

Q: What is the difference between X9318WS8IZ and X9317WS8IZ? A: Both parts are parametric equivalents with 10kΩ resistance and 100 taps. The primary difference is wiper resistance: X9317WS8IZ has 200Ω typical wiper resistance, while X9318WS8IZ has 40Ω typical. This difference does not affect substitution eligibility for standard potentiometer applications.

Q: Can DS1804Z-010+ replace X9317WS8I? A: DS1804Z-010+ is functionally compatible with identical resistance, tap count, and interface. However, it differs in temperature coefficient (750ppm/°C versus 300ppm/°C) and supports extended supply voltage range (2.7V ~ 5.5V). Circuit-level evaluation is required for applications with strict temperature stability requirements.

Q: Why is CAT5113VI-01-GT3 listed if it cannot replace X9317WS8I? A: CAT5113VI-01-GT3 is included as a reference point for similar digital potentiometer architecture. With 1kΩ resistance instead of 10kΩ, it is not a substitute for X9317WS8I but may be relevant for alternative designs requiring different resistance values.

Q: What packaging options are available for substitute parts? A: X9317WS8IZ, X9318WS8IZ, and X9C103SIZ are available in tube packaging. DS1804Z-010+ is available in tube packaging, while DS1804Z-010+T&R is available in cut tape and Digi-Reel format. Packaging selection depends on procurement and assembly requirements.

Q: Are all recommended substitutes RoHS compliant? A: All active substitute parts (X9317WS8IZ, X9318WS8IZ, X9C103SIZ, DS1804Z-010+, DS1804Z-010+T&R) are ROHS3 compliant. The original X9317WS8I is RoHS non-compliant, making the transition to compliant substitutes necessary for regulatory adherence.
