X9313WM-3 Equivalent & Substitute Parts

Part Overview

The X9313WM-3 is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a Data Acquisition component. This 10kΩ device features 32 taps with Up/Down (U/D, INC, CS) interface control, housed in an 8-MSOP surface mount package. The part is currently marked as obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations. The X9313WM-3 operates across a 3V to 5.5V supply range with non-volatile memory retention, suitable for applications requiring programmable resistance adjustment without external power maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9313WM-3 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ (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 range: 3V ~ 5.5V (exact match required)
• Taper characteristic: Linear (exact match required)
• Package type: 8-MSOP (exact match required)
• Mounting technology: Surface Mount (exact match required)

The X9313WMZ-3 satisfies all substitution criteria as a direct equivalent from the same manufacturer within the XDCP™ series, differing only in packaging format (Tube versus unspecified) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The X9313WMZ-3 is the direct functional equivalent to the X9313WM-3 across all electrical and mechanical specifications. The primary distinction lies in product lifecycle status: the X9313WM-3 is obsolete while the X9313WMZ-3 maintains active production status, ensuring continued availability and supply chain reliability.

For new designs and ongoing production requirements, the X9313WMZ-3 is the appropriate selection. This substitute provides identical electrical performance and pinout compatibility while offering improved compliance posture. The X9313WMZ-3 achieves ROHS3 compliance, whereas the X9313WM-3 is non-compliant. Both parts maintain REACH Unaffected status and share identical ECCN and HTSUS classifications.

Moisture sensitivity differs between the two variants: the X9313WM-3 carries MSL 1 (Unlimited), while the X9313WMZ-3 carries MSL 2 (1 Year). This distinction affects storage and handling protocols but does not impact functional equivalence in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the X9313WMZ-3 directly replace the X9313WM-3 in existing designs?

A: Yes. The X9313WMZ-3 is electrically and mechanically identical to the X9313WM-3. Pin configuration, resistance value, tap count, interface protocol, supply voltage range, and operating temperature specifications are equivalent. Direct PCB substitution is supported without circuit modification.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates manufacturing and supply availability. The X9313WM-3 is obsolete and no longer manufactured by Renesas Electronics Corporation. The X9313WMZ-3 remains in active production, ensuring component availability for procurement and reducing supply chain risk.

Q: How do the RoHS compliance differences affect substitution?

A: The X9313WMZ-3 meets ROHS3 compliance requirements, while the X9313WM-3 does not. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the X9313WMZ-3 is the required selection. Both parts are REACH Unaffected.

Q: What does the Moisture Sensitivity Level (MSL) difference mean?

A: MSL rating specifies maximum storage duration at specified humidity conditions before component degradation risk increases. The X9313WM-3 carries MSL 1 (Unlimited storage), while the X9313WMZ-3 carries MSL 2 (1 Year maximum storage at specified conditions). This affects inventory management and handling procedures but does not impact functional performance in deployed applications.

Q: Are the 8-MSOP and 8-TSSOP package designations interchangeable?

A: Both designations refer to the same 8-pin surface mount package with 0.118" width and 3.00mm body dimension. These are equivalent package specifications for the X9313WM-3 and X9313WMZ-3.
