X9317WM8Z Equivalent & Substitute Parts

Part Overview

The X9317WM8Z is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a data acquisition component. This 10kΩ device features 100 taps with Up/Down (U/D, INC, CS) interface control, housed in an 8-MSOP surface mount package. The part operates across 0°C to 70°C with 5V supply voltage and maintains non-volatile memory for stored settings.

The X9317WM8Z is currently in active production status. Equivalent and substitute parts become necessary when addressing supply chain constraints, inventory availability, or application-specific requirements that may benefit from alternative resistance values or expanded operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9317WM8Z is determined by the following critical parameters:

• Interface Compatibility: All substitute parts must support Up/Down (U/D, INC, CS) control interface
• Tap Configuration: 100 taps required for functional equivalence
• Package Format: 8-MSOP surface mount package mandatory
• Memory Type: Non-volatile memory required
• Taper Type: Linear taper required
• Tolerance: ±20% tolerance maintained across all substitutes
• Temperature Coefficient: ±300ppm/°C specification

The CAT5113ZI series from onsemi meets these core interface and package requirements. However, resistance value variations (1kΩ and 50kΩ options) and expanded operating temperature ranges (-40°C to 85°C) distinguish these parts as functional alternatives rather than direct pin-for-pin replacements. Supply voltage flexibility (2.5V to 6V) in CAT5113ZI variants provides broader application compatibility compared to the fixed 5V requirement of the X9317WM8Z.

Engineering Selection Recommendations

X9317WM8Z (Primary Selection)

The X9317WM8Z remains the preferred choice for new designs requiring active product status and ongoing manufacturer support. ROHS3 compliance and REACH unaffected status confirm environmental regulatory alignment. The fixed 5V supply specification suits applications with dedicated power rails. Active production status ensures long-term availability and supply chain stability.

CAT5113ZI-01-T3 (1kΩ Substitute)

Selection of the CAT5113ZI-01-T3 applies when circuit design requires lower resistance values and extended operating temperature range (-40°C to 85°C). The expanded supply voltage window (2.5V to 6V) accommodates variable power delivery systems. Obsolete product status requires confirmation of remaining inventory and end-of-life timelines before design commitment. ROHS3 compliance and REACH unaffected status maintain regulatory requirements.

CAT5113ZI-50-T3 (50kΩ Substitute)

The CAT5113ZI-50-T3 addresses applications requiring higher resistance values with identical tap resolution and interface protocol. Extended temperature range and flexible supply voltage provide operational advantages in demanding environments. Obsolete status necessitates supply chain verification. ROHS3 compliance and REACH unaffected status satisfy environmental standards.

Frequently Asked Questions (FAQ)

Q: Can CAT5113ZI parts directly replace the X9317WM8Z without circuit modification?

A: Direct replacement requires resistance value compatibility with circuit design. The CAT5113ZI-01-T3 (1kΩ) and CAT5113ZI-50-T3 (50kΩ) operate with identical interface protocols and package formats but differ in resistance specification. Circuit analysis must confirm whether the alternative resistance value maintains design function.

Q: What are the key differences between X9317WM8Z and CAT5113ZI series?

A: Primary differences include resistance value (10kΩ vs. 1kΩ or 50kΩ), operating temperature range (0°C–70°C vs. -40°C–85°C), supply voltage specification (fixed 5V vs. 2.5V–6V range), and product status (active vs. obsolete). Interface protocol, tap count, package format, and memory type remain identical.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use 8-MSOP surface mount packaging with identical 0.118" (3.00mm) width specification. PCB footprint compatibility is confirmed across X9317WM8Z, CAT5113ZI-01-T3, and CAT5113ZI-50-T3.

Q: What supply voltage considerations apply when substituting CAT5113ZI parts?

A: The X9317WM8Z requires fixed 5V supply. CAT5113ZI variants accept 2.5V to 6V range, providing flexibility in power delivery design. Circuits designed for 5V operation remain compatible with CAT5113ZI parts, but the expanded voltage window enables operation across broader power supply configurations.

Q: How does product status affect substitution decisions?

A: X9317WM8Z active status ensures ongoing manufacturer support, design documentation updates, and supply continuity. CAT5113ZI obsolete status indicates discontinued production. Substitution with obsolete parts requires inventory verification, end-of-life date confirmation, and assessment of long-term availability for production quantities.

Q: Are temperature coefficient specifications equivalent across all three parts?

A: Temperature coefficient values are equivalent: ±300ppm/°C for X9317WM8Z and 300ppm/°C for CAT5113ZI variants. Operating temperature ranges differ (0°C–70°C vs. -40°C–85°C), affecting application suitability in extreme thermal environments.
