X9317TS8 Digital Potentiometer - Equivalent & Substitute Parts

Part Overview

The X9317TS8 is a digital potentiometer manufactured by Renesas Electronics Corporation, featuring 100k Ohm resistance with 100 taps and Up/Down (U/D, INC, CS) interface control. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates on 5V supply with linear taper configuration and non-volatile memory, suitable for precision analog signal adjustment applications in data acquisition systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the X9317TS8 is determined by the following critical parameters that must align for functional compatibility:

Primary Matching Criteria:

• Resistance value: 100k Ohm
• Number of taps: 100
• Interface type: Up/Down (U/D, INC, CS)
• Number of circuits: 1
• Memory type: Non-Volatile
• Package: 8-SOIC
• Taper: Linear

Secondary Compatibility Factors:

• Supply voltage range (must accommodate 5V operation)
• Tolerance specification (±20%)
• Mounting type (Surface Mount)
• Temperature coefficient performance

Substitute parts are grouped into two categories: parametric equivalents (matching all primary criteria) and similar alternatives (matching core functional parameters with noted deviations).

Engineering Selection Recommendations

X9C104SZ (Parametric Equivalent - Recommended Primary Substitute)

The X9C104SZ is a parametric equivalent manufactured by Renesas Electronics Corporation with identical electrical specifications to the X9317TS8. This part matches all primary functional criteria: 100k Ohm resistance, 100 taps, U/D/INC/CS interface, and 8-SOIC package. The X9C104SZ holds active product status and is ROHS3 compliant, providing superior compliance posture compared to the obsolete, RoHS non-compliant X9317TS8. Inventory availability is substantial at 2100 pieces. The primary difference is wiper resistance (40 Ohms typical versus 200 Ohms), which does not affect functional substitution for standard applications.

DS1804Z-100+ and DS1804Z-100+T&R (Active Alternatives)

Both DS1804Z variants from Analog Devices Inc./Maxim Integrated provide 100k Ohm resistance with 100 taps and identical interface configuration. These parts support extended supply voltage range (2.7V ~ 5.5V) and expanded operating temperature (-40°C ~ 85°C), offering broader application flexibility. Both variants are ROHS3 compliant and actively produced. The DS1804Z-100+T&R includes Cut Tape and Digi-Reel packaging, providing supply chain flexibility. Temperature coefficient is 750ppm/°C, higher than the X9317TS8 specification of ±300ppm/°C. Inventory levels are robust at 2260 and 3400 pieces respectively.

CAT5113VI-01-GT3 (Limited Compatibility)

The CAT5113VI-01-GT3 from onsemi provides identical interface and tap configuration but differs in resistance value (1k Ohm versus 100k Ohm). This part is suitable only for applications where 1k Ohm resistance is functionally acceptable. The part is obsolete and ROHS3 compliant. This substitute is not recommended for direct replacement in circuits designed for 100k Ohm operation.

Frequently Asked Questions (FAQ)

Q: Can X9C104SZ directly replace X9317TS8 in existing designs?

A: Yes. The X9C104SZ is a parametric equivalent with matching resistance (100k Ohm), tap count (100), interface (U/D, INC, CS), and package (8-SOIC). Both parts operate on 5V supply with non-volatile memory and linear taper. The wiper resistance difference (40 Ohms versus 200 Ohms) does not affect functional compatibility in standard applications.

Q: What is the primary advantage of DS1804Z-100+ over X9317TS8?

A: The DS1804Z-100+ offers extended supply voltage range (2.7V ~ 5.5V versus 5V fixed), expanded operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), and active product status with ROHS3 compliance. These characteristics provide superior design flexibility and regulatory compliance for new designs.

Q: Why is CAT5113VI-01-GT3 listed as a substitute if the resistance differs?

A: CAT5113VI-01-GT3 is listed as a similar alternative based on matching interface, tap configuration, and package. However, the 1k Ohm resistance value differs significantly from the 100k Ohm specification. This part is suitable only for applications where 1k Ohm operation is functionally equivalent or where circuit design permits resistance value adjustment.

Q: Are all substitute parts available in 8-SOIC package?

A: Yes. All listed substitute parts are packaged in 8-SOIC (0.154", 3.90mm Width), ensuring mechanical and electrical compatibility with existing PCB layouts designed for X9317TS8.

Q: What compliance considerations apply to substitute selection?

A: The X9317TS8 is RoHS non-compliant. All active substitute parts (X9C104SZ, DS1804Z-100+, DS1804Z-100+T&R) are ROHS3 compliant, meeting current regulatory requirements. CAT5113VI-01-GT3 is also ROHS3 compliant but is obsolete. For new designs, ROHS3 compliant alternatives are recommended.

Q: How do temperature coefficients affect substitute selection?

A: The X9317TS8 specifies ±300ppm/°C temperature coefficient. X9C104SZ matches this specification exactly. DS1804Z variants specify 750ppm/°C, indicating greater temperature sensitivity. For applications requiring tight temperature stability, X9C104SZ is the preferred substitute. For applications with relaxed temperature requirements, DS1804Z variants are acceptable.

Q: What packaging options are available for substitute parts?

A: X9C104SZ is supplied in Tube packaging. DS1804Z-100+ is supplied in Tube packaging. DS1804Z-100+T&R is supplied in Cut Tape and Digi-Reel packaging, providing flexibility for automated assembly processes. CAT5113VI-01-GT3 is supplied in Cut Tape packaging.
