Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9314WS-3T2 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)
• Number of Circuits: 1 (exact match required)
• Taper Characteristic: Logarithmic (exact match required)
• Memory Type: Non-Volatile (exact match required)
• Package Configuration: 8-SOIC form factor (exact match required)
• Supply Voltage Range: 3V ~ 5.5V (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)

The X9314WSZ-3T1 meets all substitution criteria. The primary distinction between the main part and its substitute is packaging format (bulk versus Tape & Reel) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The X9314WSZ-3T1 is the direct functional substitute for the X9314WS-3T2. All electrical and mechanical parameters are identical. Selection between these parts should be based on the following factors:

Product Status: The X9314WS-3T2 is obsolete. The X9314WSZ-3T1 is active and represents the current production equivalent.

Compliance: The X9314WSZ-3T1 is ROHS3 compliant, whereas the X9314WS-3T2 is RoHS non-compliant. For applications subject to RoHS regulations, the X9314WSZ-3T1 is the required choice.

Moisture Sensitivity: The X9314WSZ-3T1 has MSL 1 (unlimited shelf life), compared to MSL 3 (168 hours) for the X9314WS-3T2. This provides superior handling and storage flexibility.

Packaging: The X9314WSZ-3T1 is supplied in Tape & Reel format, standard for production environments. The X9314WS-3T2 bulk packaging is no longer actively produced.

For new designs and ongoing production, the X9314WSZ-3T1 is the appropriate selection. For legacy system maintenance where the original part is unavailable, the X9314WSZ-3T1 provides full functional compatibility with improved compliance and reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the X9314WSZ-3T1 be used as a direct replacement for the X9314WS-3T2 in existing designs?

A: Yes. All electrical specifications, pin configurations, and functional parameters are identical. The X9314WSZ-3T1 is a direct substitute with no circuit modifications required.

Q: What is the difference between the X9314WS-3T2 and X9314WSZ-3T1?

A: The parts are electrically and mechanically identical. Differences are limited to product lifecycle status (obsolete versus active), packaging format (bulk versus Tape & Reel), RoHS compliance (non-compliant versus ROHS3 compliant), and moisture sensitivity rating (MSL 3 versus MSL 1).

Q: Why is the X9314WS-3T2 listed as obsolete?

A: The X9314WS-3T2 has been discontinued by Renesas Electronics Corporation. The X9314WSZ-3T1 is the active production equivalent.

Q: Are there any pin configuration differences between these parts?

A: No. Both parts use the 8-SOIC package with identical pin assignments and interface protocols.

Q: What does the packaging designation "Tape & Reel (TR)" mean?

A: Tape & Reel is the standard production packaging format for surface mount components. Components are wound on continuous tape for automated assembly equipment. This is the current standard for the X9314WSZ-3T1.

Q: Does the RoHS compliance difference affect functionality?

A: No. RoHS compliance is a regulatory and environmental requirement, not a functional specification. The X9314WSZ-3T1 meets RoHS3 standards, making it suitable for applications subject to RoHS regulations.

Q: What does MSL 1 versus MSL 3 mean for handling?

A: MSL (Moisture Sensitivity Level) indicates shelf life under controlled storage conditions. MSL 1 (unlimited) means the X9314WSZ-3T1 has no time-based storage restrictions. MSL 3 (168 hours) means the X9314WS-3T2 must be used within 168 hours of opening the original packaging under specified humidity conditions.
