X9314WS Digital Potentiometer Equivalent & Substitute Parts

Part Overview

The X9314WS is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a data acquisition component. This 10kΩ, 32-tap device features a logarithmic taper and operates via Up/Down (U/D, INC, CS) interface with non-volatile memory. The part is currently listed as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. The X9314WS is packaged in 8-SOIC surface mount configuration and operates across a 0°C to 70°C temperature range with 5V supply voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the X9314WS 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: 5V (exact match required)
• Taper characteristic: Logarithmic (exact match required)
• Package type: 8-SOIC (exact match required)
• Temperature coefficient: ±600ppm/°C (exact match required)

The X9314WSZ qualifies as a direct substitute based on identical electrical specifications, functional interface, and mechanical packaging. The primary distinction between these parts is product status and packaging format, not electrical or functional performance.

Parameter Comparison

Engineering Selection Recommendations

The X9314WSZ is the direct functional equivalent of the X9314WS. Both parts share identical electrical characteristics, interface specifications, and mechanical packaging. Selection between these parts should be based on the following criteria:

X9314WS: Use only when legacy stock is available and RoHS non-compliance is acceptable for the application. Product status is obsolete; new procurement is not recommended.

X9314WSZ: Recommended for all new designs and ongoing production. This part maintains active product status with Renesas Electronics Corporation and meets ROHS3 compliance requirements. Packaging is supplied in tube format. Electrical and functional performance is identical to the X9314WS, ensuring direct substitution without circuit redesign or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the X9314WSZ replace the X9314WS in existing designs?

A: Yes. The X9314WSZ is electrically and functionally identical to the X9314WS. All electrical parameters, interface protocols, and mechanical dimensions match exactly. Direct substitution is possible without circuit modification.

Q: What is the difference between X9314WS and X9314WSZ?

A: The primary differences are product status and packaging format. The X9314WS is obsolete and supplied in unspecified packaging. The X9314WSZ is active and supplied in tube packaging. The X9314WSZ also meets ROHS3 compliance, whereas the X9314WS is RoHS non-compliant. Electrical specifications are identical.

Q: Why is the X9314WS listed as obsolete?

A: Obsolescence is a manufacturer designation indicating the part is no longer in active production. The X9314WSZ serves as the active replacement within the same product family.

Q: Are there any compatibility concerns when switching from X9314WS to X9314WSZ?

A: No compatibility concerns exist. Both parts use identical 8-SOIC packaging, pinout, electrical interface, and functional specifications. PCB layout and firmware remain unchanged.

Q: Does the X9314WSZ meet current regulatory requirements?

A: Yes. The X9314WSZ is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What is the difference in packaging between these parts?

A: The X9314WS packaging format is not specified in available documentation. The X9314WSZ is supplied in tube packaging. Both use the same 8-SOIC physical form factor.
