Part Overview

The X9319WS8Z is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a data acquisition component. This 10kΩ, 100-tap device features a linear taper configuration with Up/Down (U/D, INC, CS) interface control and non-volatile memory. The part operates at 5V supply voltage with an operating temperature range of 0°C to 70°C in an 8-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9319WS8Z 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 type: 8-SOIC
• Mounting type: Surface Mount

Secondary Compatibility Factors:

• Supply voltage compatibility (5V nominal or wider range including 5V)
• Operating temperature range (must support minimum 0°C to 70°C)
• Tolerance specification (±20%)
• Wiper resistance characteristics

Substitute parts are categorized as follows:

Direct Manufacturer Equivalents: Parts with identical electrical specifications and the same base product line (X9C103 series), differing only in packaging or product status.

Parametric Equivalents: Parts from the same manufacturer (Renesas XDCP™ series) with identical core specifications but variations in wiper resistance or operating temperature range that remain within acceptable design parameters.

Similar Cross-Manufacturer Alternatives: Parts from alternative manufacturers (onsemi CAT5113, Analog Devices DS1804) that meet the primary substitution criteria but may have different supply voltage ranges, temperature coefficients, or wiper resistance values.

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitutes (Renesas XDCP™ Series):

X9C103SIZ and X9C103SZ are the preferred direct substitutes for the X9319WS8Z. Both parts are active products from Renesas with identical 10kΩ resistance, 100-tap configuration, and 40Ω wiper resistance. These parts maintain full compatibility with the original design while offering extended operating temperature range (-40°C to 85°C) and improved product availability. Both are ROHS3 compliant with MSL 1 rating.

X9318WS8Z is an alternative Renesas substitute with identical electrical specifications and matching 0°C to 70°C operating temperature range. This part provides direct thermal compatibility with the original design while maintaining active product status.

Secondary Substitutes (Renesas XDCP™ Series):

X9317WS8Z is a parametric equivalent with identical core specifications but features 200Ω wiper resistance compared to the original 40Ω. This part is suitable only when wiper resistance variation is acceptable within the application circuit design.

Cross-Manufacturer Alternatives:

DS1804Z-010+ and DS1804Z-010+T&R (Analog Devices Inc./Maxim Integrated) are functionally equivalent 10kΩ, 100-tap digital potentiometers with identical interface and package specifications. These parts support wider supply voltage range (2.7V to 5.5V) and extended operating temperature (-40°C to 85°C). The primary design consideration is the 400Ω wiper resistance versus the original 40Ω specification. Both are active products with ROHS3 compliance.

Not Recommended:

CAT5113VI-01-GT3 (onsemi) is not recommended as a substitute. Although it shares the same interface type and package, the 1kΩ resistance value differs fundamentally from the 10kΩ specification, making it unsuitable for direct replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can X9C103SIZ be used as a direct replacement for X9319WS8Z?

A: Yes. X9C103SIZ is a direct substitute with identical 10kΩ resistance, 100-tap configuration, U/D interface, and 40Ω wiper resistance. The extended operating temperature range (-40°C to 85°C) provides additional thermal margin beyond the original 0°C to 70°C specification. Both parts are packaged in 8-SOIC and are ROHS3 compliant.

Q: What is the difference between X9318WS8Z and X9317WS8Z?

A: Both are Renesas XDCP™ series 10kΩ, 100-tap digital potentiometers in 8-SOIC packages. The primary difference is wiper resistance: X9318WS8Z has 40Ω wiper resistance (matching the original X9319WS8Z), while X9317WS8Z has 200Ω wiper resistance. Select X9318WS8Z for direct electrical compatibility or X9317WS8Z only if the application circuit design accommodates higher wiper resistance.

Q: Can DS1804Z-010+ replace X9319WS8Z?

A: DS1804Z-010+ is functionally compatible with identical 10kΩ resistance, 100-tap configuration, and U/D interface in 8-SOIC package. However, the wiper resistance is 400Ω compared to the original 40Ω, and the temperature coefficient is 750ppm/°C versus ±300ppm/°C. Verify circuit design compatibility before substitution. The part is active and ROHS3 compliant.

Q: Why is CAT5113VI-01-GT3 listed but not recommended?

A: CAT5113VI-01-GT3 has a 1kΩ resistance value, which is fundamentally different from the 10kΩ specification of X9319WS8Z. Although it shares the same interface type and 8-SOIC package, the resistance mismatch makes it unsuitable for direct replacement without complete circuit redesign.

Q: What packaging options are available for substitutes?

A: Renesas substitutes (X9C103SIZ, X9C103SZ, X9318WS8Z) are supplied in Tube packaging. Analog Devices DS1804Z-010+ is available in Tube packaging, while DS1804Z-010+T&R is supplied in Cut Tape (CT) & Digi-Reel® format. Select packaging based on assembly process requirements and order quantity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (X9C103SIZ, X9C103SZ, X9318WS8Z, X9317WS8Z, DS1804Z-010+, DS1804Z-010+T&R) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original X9319WS8Z compliance status.

Q: What is the supply voltage consideration for cross-manufacturer substitutes?

A: The original X9319WS8Z operates at 5V nominal supply. Renesas substitutes maintain 5V specification. Analog Devices DS1804Z series supports 2.7V to 5.5V supply range, providing wider voltage compatibility. Verify power supply specifications in the application circuit before substitution.
