X9313WM Digital Potentiometer 10k Ohm Equivalent & Substitute Parts

Part Overview

The X9313WM is a digital potentiometer manufactured by Renesas Electronics Corporation, featuring 10k Ohm resistance with 32 taps and Up/Down (U/D, INC, CS) interface control. This component belongs to the XDCP™ series and is classified as data acquisition integrated circuitry in 8-MSOP surface mount packaging.

The X9313WM is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9313WM is determined by strict alignment with the following critical parameters:

• Resistance value: 10k Ohm (exact match required)
• Number of taps: 32 (exact match required)
• Interface protocol: Up/Down (U/D, INC, CS) (exact match required)
• Memory type: Non-Volatile (exact match required)
• Supply voltage: 5V (exact match required)
• Package type: 8-MSOP (exact match required)
• Number of circuits: 1 (exact match required)

Substitute parts are grouped into two categories:

Direct Manufacturer Substitute: X9313WMZ — identical part number base with packaging variant (Tube packaging vs. unspecified original packaging).

Parametric Equivalent: X9315WMZ — shares all critical electrical and mechanical parameters with one exception: wiper resistance is 200 Ohms (typical) versus 40 Ohms (typical) in the X9313WM. This difference does not affect substitution eligibility when wiper resistance variation is acceptable in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

X9313WMZ (Direct Manufacturer Substitute): This part is the primary recommended substitute. It maintains identical electrical and mechanical specifications to the X9313WM while offering active product status and ROHS3 compliance. The packaging format differs (Tube vs. unspecified), but functional compatibility is complete. Inventory availability is 680 units.

X9315WMZ (Parametric Equivalent): This part qualifies as a parametric equivalent due to matching all critical parameters except typical wiper resistance (200 Ohms vs. 40 Ohms). Selection of this part is appropriate only when circuit design accommodates the higher wiper resistance specification. The X9315WMZ offers active product status, ROHS3 compliance, and higher inventory availability (1131 units).

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, addressing regulatory requirements that the obsolete X9313WM does not meet.

Frequently Asked Questions (FAQ)

Q: Can X9313WMZ be used as a direct replacement for X9313WM?

A: Yes. The X9313WMZ is a direct manufacturer substitute with identical electrical specifications, interface protocol, resistance value, tap count, and package type. The only difference is packaging format (Tube). Functional compatibility is complete.

Q: What is the difference between X9313WMZ and X9315WMZ?

A: Both parts share the same resistance value (10k Ohm), tap count (32), interface type, supply voltage, and package. The primary difference is typical wiper resistance: X9313WMZ has 40 Ohms while X9315WMZ has 200 Ohms. This affects circuit behavior in applications sensitive to wiper impedance.

Q: Is X9315WMZ compatible with designs using X9313WM?

A: X9315WMZ is parametrically equivalent and compatible when the application circuit can tolerate the higher wiper resistance (200 Ohms vs. 40 Ohms). Circuit simulation or testing is necessary to confirm performance in applications with tight wiper impedance requirements.

Q: What are the compliance differences between the main part and substitutes?

A: The X9313WM is RoHS non-compliant with MSL 1 (Unlimited). Both X9313WMZ and X9315WMZ are ROHS3 compliant with MSL 2 (1 Year), meeting current regulatory standards.

Q: Which substitute should be selected for new designs?

A: X9313WMZ is recommended for designs requiring exact electrical equivalence to the X9313WM. X9315WMZ is suitable when wiper resistance variation is acceptable and higher inventory availability is beneficial.

Q: Are all three parts in the same package?

A: Yes. All three parts use 8-MSOP surface mount packaging with identical physical dimensions (0.118", 3.00mm Width).
