Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the X9315WS are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters for Substitution:

• Resistance value: 10k Ohm
• Number of taps: 32
• Interface type: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage: 5V
• Package type: 8-SOIC
• Mounting type: Surface Mount

Substitute Classification:

Direct Manufacturer Substitute: X9315WSZ matches all critical electrical parameters and package specifications. The only difference is packaging format (Tube vs. unspecified for main part) and active product status, making it a direct functional replacement.

Parametric Equivalent: X9313WSZ shares all critical electrical parameters and package specifications with one exception: the wiper resistance is 40 Ohms (typical) compared to 200 Ohms for the X9315WS. This difference in wiper resistance does not affect the core potentiometer function but may impact circuit performance in applications sensitive to wiper impedance characteristics.

Engineering Selection Recommendations

X9315WSZ (Direct Substitute): This part is the primary recommended substitute for the obsolete X9315WS. It maintains identical electrical specifications, package configuration, and compliance certifications. The X9315WSZ carries Active product status, ensuring long-term availability and supply chain support. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

X9313WSZ (Parametric Equivalent): This part provides functional equivalence with all critical parameters matching the X9315WS except for wiper resistance (40 Ohms vs. 200 Ohms). The X9313WSZ is also Active status with identical compliance certifications. Selection of this part requires circuit-level analysis to confirm that the lower wiper resistance does not impact system performance or signal integrity.

Both substitute parts are manufactured by Renesas Electronics Corporation and maintain the same XDCP™ series designation, ensuring design compatibility and consistent performance characteristics within the specified operating temperature range of 0°C to 70°C.

Frequently Asked Questions (FAQ)

Q: Can X9315WSZ be used as a direct replacement for X9315WS?

A: Yes. The X9315WSZ is a direct functional equivalent with identical electrical parameters, interface specifications, package type, and compliance certifications. The only difference is packaging format (Tube) and active product status.

Q: What is the difference between X9315WSZ and X9313WSZ?

A: Both parts share the same 10k Ohm resistance, 32-tap configuration, Up/Down interface, and 8-SOIC package. The primary difference is wiper resistance: X9315WSZ has 200 Ohms typical wiper resistance, while X9313WSZ has 40 Ohms typical wiper resistance. This affects circuit impedance characteristics but does not change the core potentiometer function.

Q: Is the X9313WSZ suitable for my application if I need the X9315WS?

A: The X9313WSZ is electric
