X9116WM8Z Digital Potentiometer Equivalent & Substitute Parts

Part Overview

The X9116WM8Z is a digital potentiometer manufactured by Renesas Electronics Corporation, featuring 10kΩ resistance with 16 taps and a linear taper configuration. This component operates with an Up/Down (U/D, INC, CS) interface and includes non-volatile memory for persistent settings. The X9116WM8Z is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. Active alternatives with compatible electrical and mechanical specifications are available to maintain system functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9116WM8Z is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 10kΩ
• Interface type: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage: 5V
• Mounting type: Surface Mount
• Package type: 8-MSOP
• Taper: Linear
• Number of circuits: 1

Allowable Variation Parameters:

• Number of taps: May increase (provides finer resolution without functional incompatibility)
• Product status: Active substitutes preferred for obsolete parts
• Inventory availability: Secondary consideration

The X9315WMZ meets all mandatory matching parameters while providing enhanced tap resolution (32 taps versus 16 taps), offering improved granularity in potentiometer adjustment without compromising interface compatibility or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The X9315WMZ is a direct functional substitute for the X9116WM8Z based on electrical and mechanical parameter equivalence. Both components maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and identical MSL ratings. The X9315WMZ is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete X9116WM8Z.

The primary technical difference is the increased tap count (32 versus 16), which provides finer resolution in potentiometer adjustment. This enhancement does not introduce incompatibility with existing circuit designs, as the interface protocol, voltage requirements, and package footprint remain unchanged. The substitute component is suitable for direct replacement in applications requiring the X9116WM8Z.

Frequently Asked Questions (FAQ)

Q: Can the X9315WMZ directly replace the X9116WM8Z in existing designs?

A: Yes. The X9315WMZ maintains identical electrical specifications, interface protocol, supply voltage, package type, and mounting configuration. The increased tap count (32 versus 16) provides enhanced resolution without affecting circuit compatibility.

Q: What is the significance of the increased tap count in the X9315WMZ?

A: The 32-tap configuration provides finer granularity in resistance adjustment compared to the 16-tap X9116WM8Z. Both components span the same 10kΩ resistance range, but the X9315WMZ offers smaller step increments between tap positions.

Q: Are the compliance certifications identical between these components?

A: Yes. Both the X9116WM8Z and X9315WMZ carry ROHS3 compliance, REACH Unaffected status, and identical MSL ratings of 2 (1 Year).

Q: Why is the X9116WM8Z listed as obsolete?

A: The X9116WM8Z has been discontinued by Renesas Electronics Corporation. The X9315WMZ represents the active alternative within the XDCP™ series for equivalent 10kΩ digital potentiometer applications.

Q: Are there any package or footprint differences between these parts?

A: No. Both components use the 8-MSOP package with identical physical dimensions (0.118", 3.00mm Width), ensuring direct PCB compatibility without layout modifications.

Q: What is the operating temperature range for both components?

A: Both the X9116WM8Z and X9315WMZ operate across 0°C to 70°C, with identical temperature coefficients of ±300ppm/°C.
