Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9313WS-3T2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ
• Number of taps: 32
• Number of circuits: 1
• Interface protocol: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage range: 3V ~ 5.5V
• Package type: 8-SOIC
• Taper characteristic: Linear

The X9313WSZ-3T1 meets all these criteria and is therefore classified as a direct equivalent substitute. Differences in packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete) do not affect functional or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The X9313WSZ-3T1 is the direct functional equivalent of the X9313WS-3T2. Selection between these parts should be based on the following factors:

Product Status: The X9313WS-3T2 is obsolete, while the X9313WSZ-3T1 is active. For new designs or long-term production requirements, the X9313WSZ-3T1 is the appropriate choice to ensure ongoing availability and supply chain stability.

Compliance: The X9313WSZ-3T1 is ROHS3 compliant, whereas the X9313WS-3T2 is RoHS non-compliant. Applications subject to RoHS regulations require the X9313WSZ-3T1.

Packaging: The X9313WSZ-3T1 is supplied in Tape & Reel format, suitable for automated assembly processes. The X9313WS-3T2 was supplied in bulk packaging. Packaging selection depends on production volume and assembly methodology.

All electrical and functional parameters are identical between the two parts, ensuring direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the X9313WSZ-3T1 be used as a direct replacement for the X9313WS-3T2 in existing designs?

A: Yes. The X9313WSZ-3T1 is electrically and functionally identical to the X9313WS-3T2. All critical parameters—resistance value, tap count, interface protocol, supply voltage, and package dimensions—are equivalent. No circuit modifications are required.

Q: What is the difference between the X9313WS-3T2 and X9313WSZ-3T1?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (bulk vs. Tape & Reel). Electrical performance and pinout are identical.

Q: Why is the X9313WS-3T2 listed as obsolete?

A: Obsolescence is a manufacturer designation indicating that the part is no longer in active production. The X9313WSZ-3T1 is the active equivalent and should be used for new designs and ongoing production.

Q: Are there any compatibility concerns when switching from X9313WS-3T2 to X9313WSZ-3T1?

A: No compatibility concerns exist. Both parts share the same 8-SOIC package footprint, pinout, and electrical specifications. PCB layout and firmware remain unchanged.

Q: Does the Tape & Reel packaging of the X9313WSZ-3T1 affect performance?

A: No. Packaging format does not affect electrical performance or functionality. Tape & Reel packaging is optimized for automated assembly processes and does not alter component behavior.

Q: Is the X9313WSZ-3T1 suitable for applications requiring RoHS compliance?

A: Yes. The X9313WSZ-3T1 is ROHS3 compliant. The X9313WS-3T2 is not RoHS compliant and cannot be used in applications with RoHS requirements.
