X9313WM-3T1 Equivalent & Substitute Parts

Part Overview

The X9313WM-3T1 is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a data acquisition component. This device features a 10kΩ resistance network with 32 taps, supporting up/down (U/D, INC, CS) interface control and non-volatile memory storage. The part operates across a 3V to 5.5V supply range with linear taper characteristics.

The X9313WM-3T1 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the X9313WM-3T1 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Resistance value: 10kΩ
• Number of taps: 32
• Number of circuits: 1
• Interface type: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage range: 3V ~ 5.5V
• Taper characteristic: Linear
• Package type: 8-MSOP
• Tolerance: ±20%
• Temperature coefficient: ±300ppm/°C
• Wiper resistance: 40Ω typical
• Operating temperature: 0°C ~ 70°C

The X9313WMZ-3T1 meets all critical electrical and mechanical parameters. The primary difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete), with improved RoHS3 compliance and updated moisture sensitivity specifications.

Parameter Comparison

Engineering Selection Recommendations

The X9313WMZ-3T1 is the direct substitute for the obsolete X9313WM-3T1. Both parts share identical electrical specifications, interface characteristics, and mechanical dimensions. Selection between these parts is determined by product availability and compliance requirements.

The X9313WMZ-3T1 offers the advantage of active product status, ensuring continued manufacturer support and availability. This part also provides ROHS3 compliance, meeting current environmental and regulatory standards. The updated moisture sensitivity level (MSL 2, 1 Year) reflects current industry packaging standards.

For applications requiring RoHS non-compliant components or unlimited moisture sensitivity handling, the X9313WM-3T1 remains functionally equivalent where inventory permits. However, the X9313WMZ-3T1 is the recommended selection for new designs and ongoing production due to its active status and improved compliance profile.

Frequently Asked Questions (FAQ)

Q: Are the X9313WM-3T1 and X9313WMZ-3T1 electrically identical?

A: Yes. Both parts feature identical resistance values (10kΩ), tap counts (32), interface protocols (U/D, INC, CS), supply voltage ranges (3V ~ 5.5V), temperature coefficients (±300ppm/°C), and operating temperature ranges (0°C ~ 70°C). Electrical performance is equivalent.

Q: What is the difference between these parts?

A: The primary differences are product status (Obsolete versus Active), packaging format (Bulk versus Tape & Reel), RoHS compliance (non-compliant versus ROHS3 Compliant), and moisture sensitivity level (MSL 1 versus MSL 2). Electrical and mechanical specifications are identical.

Q: Can I use X9313WMZ-3T1 as a direct replacement in existing designs?

A: Yes. The X9313WMZ-3T1 is a direct substitute. The 8-MSOP package dimensions, pin configuration, and electrical characteristics are identical. No circuit modifications are required.

Q: Why is the X9313WM-3T1 marked as obsolete?

A: The X9313WM-3T1 has reached end-of-life status. Renesas Electronics Corporation continues to support the X9313WMZ-3T1 variant as the active product line continuation.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) packaging and bulk packaging contain identical components. Packaging format affects only handling, storage, and automated assembly compatibility, not electrical or mechanical performance.

Q: Are there RoHS compliance implications for substitution?

A: The X9313WM-3T1 is RoHS non-compliant, while X9313WMZ-3T1 is ROHS3 Compliant. For applications subject to RoHS regulations, the X9313WMZ-3T1 is required. For legacy systems without RoHS requirements, both parts are functionally equivalent.

Q: What is the moisture sensitivity difference between MSL 1 and MSL 2?

A: MSL 1 (Unlimited) indicates no time-based moisture absorption restrictions. MSL 2 (1 Year) specifies a one-year shelf life limit under controlled humidity conditions. Storage and handling procedures differ accordingly.
