X9315WM Digital Potentiometer 10k Ohm Equivalent & Substitute Parts

Part Overview

The X9315WM is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a Data Acquisition component. This 10k Ohm, 32-tap device features a linear taper configuration with Up/Down (U/D, INC, CS) interface control and non-volatile memory. The X9315WM operates at 5V supply voltage with surface mount packaging in 8-MSOP format.

The X9315WM is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production, maintenance, and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the X9315WM are identified based on strict parametric equivalence across the following critical parameters:

• Resistance value: 10k Ohm
• Number of taps: 32
• Interface type: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage: 5V
• Taper configuration: Linear
• Package format: 8-MSOP
• Operating temperature range: 0°C ~ 70°C

The X9315WMZ and X9313WMZ meet these core functional requirements. Both parts are manufactured by Renesas Electronics Corporation within the XDCP™ series and maintain identical electrical specifications for resistance, tap count, interface protocol, and operating conditions. Differences in wiper resistance and compliance status are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

X9315WMZ is the primary substitute for the X9315WM. Both parts share identical wiper resistance (200 Ohms typical) and are functionally equivalent across all core electrical parameters. The X9315WMZ is currently in active production status and carries ROHS3 compliance certification, addressing regulatory requirements for new designs and production environments where RoHS compliance is mandated.

X9313WMZ is a secondary substitute option. While it maintains all critical functional parameters (10k resistance, 32 taps, Up/Down interface, non-volatile memory, 5V operation), it differs in wiper resistance specification (40 Ohms typical versus 200 Ohms). This difference may affect circuit performance in applications where wiper impedance is a design constraint. X9313WMZ is also active production status with ROHS3 compliance.

Selection between X9315WMZ and X9313WMZ depends on wiper resistance requirements specific to the application circuit. Both parts are available in tube packaging with improved moisture sensitivity ratings (MSL 2) compared to the obsolete X9315WM.

Frequently Asked Questions (FAQ)

Q: Can X9315WMZ directly replace X9315WM in existing designs?

A: Yes. The X9315WMZ maintains identical electrical specifications including 10k resistance, 32-tap configuration, Up/Down interface protocol, non-volatile memory, 5V supply voltage, and 8-MSOP package format. Pin-to-pin compatibility is
