X9313WST2 Digital Potentiometer Equivalent & Substitute Parts

Part Overview

The X9313WST2 is a 10kΩ digital potentiometer manufactured by Renesas Electronics Corporation, featuring a single circuit with 32 taps and an Up/Down (U/D, INC, CS) interface in an 8-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates at 5V supply voltage with non-volatile memory and linear taper characteristics suitable for data acquisition applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the X9313WST2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ
• Number of taps: 32
• Interface protocol: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage: 5V
• Package type: 8-SOIC
• Mounting configuration: Surface Mount

The X9313WSZT1 qualifies as a direct manufacturer substitute, maintaining identical electrical and mechanical specifications while offering improved product status (Active vs. Obsolete) and RoHS3 compliance. The X9315WSZT1 is a parametric equivalent that shares all core functional parameters with one exception: the wiper resistance is 200Ω instead of 40Ω. This difference may impact circuit performance in applications where wiper impedance is critical.

Parameter Comparison

Engineering Selection Recommendations

The X9313WSZT1 is the primary substitute for the obsolete X9313WST2. Both parts maintain identical electrical and mechanical specifications, with the X9313WSZT1 offering the advantage of Active product status and ROHS3 compliance. This part is suitable for direct replacement in existing designs without circuit modification.

The X9315WSZT1 serves as a parametric equivalent for applications where wiper resistance variation is acceptable. The 200Ω wiper resistance (versus 40Ω in the X9313WST2) represents a five-fold increase and may affect circuit performance in high-impedance signal paths or precision applications. Selection of the X9315WSZT1 requires circuit-level analysis to confirm compatibility with the higher wiper impedance.

Both substitute parts are manufactured by Renesas Electronics Corporation and maintain the same XDCP™ series designation, interface protocol, and package footprint as the original part.

Frequently Asked Questions (FAQ)

Q: Can the X9313WSZT1 be used as a direct replacement for the X9313WST2?

A: Yes. The X9313WSZT1 maintains identical electrical specifications, package configuration, and interface protocol. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit modifications are required.

Q: What is the significance of the wiper resistance difference between X9313WSZT1 and X9315WSZT1?

A: The X9313WSZT1 has a typical wiper resistance of 40Ω, while the X9315WSZT1 has 200Ω. This parameter affects the output impedance of the potentiometer and may impact circuit performance in applications sensitive to source impedance. Verify circuit compatibility before substituting the X9315WSZT1.

Q: Are the packaging options different between the substitute parts?

A: Yes. The X9313WSZT1 is available in Cut Tape (CT) and Digi-Reel® packaging, while the X9315WSZT1 is supplied in Tape & Reel (TR) format. Both use the same 8-SOIC package footprint. Confirm packaging requirements for your procurement and assembly process.

Q: Do both substitute parts meet current compliance standards?

A: Both the X9313WSZT1 and X9315WSZT1 are ROHS3 compliant and REACH unaffected. The original X9313WST2 is RoHS non-compliant, making the substitutes suitable for applications requiring modern regulatory compliance.

Q: What is the base product number relationship between these parts?

A: The X9313WST2 and X9313WSZT1 share the base product number X9313, indicating they are variants within the same product line. The X9315WSZT1 uses base product number X9315, representing a different product variant within the XDCP™ series.
