X9315WPI Digital Potentiometer Equivalent & Substitute Parts

Part Overview

The X9315WPI is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a Data Acquisition component. It features a 10kΩ resistance network with 32 taps, linear taper, and Up/Down (U/D, INC, CS) interface control. The device operates on a 5V supply with non-volatile memory and is housed in an 8-PDIP through-hole package.

The X9315WPI is currently listed as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this digital potentiometer.

Substitute Part Grouping Explanation

Substitute parts for the X9315WPI are identified based on strict equivalence of core electrical and functional parameters. The substitution criteria are:

• Resistance value: 10kΩ (exact match required)
• Number of taps: 32 (exact match required)
• Number of circuits: 1 (exact match required)
• Interface type: Up/Down (U/D, INC, CS) (exact match required)
• Taper characteristic: Linear (exact match required)
• Memory type: Non-Volatile (exact match required)
• Supply voltage: 5V (exact match required)
• Temperature coefficient: ±300ppm/°C (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Wiper resistance: 200Ω typical (exact match required)
• Base product number: X9315 (same family)

The X9315WSIZ meets all electrical and functional equivalence criteria. The primary difference is the package type: X9315WSIZ uses 8-SOIC surface-mount packaging instead of the through-hole 8-PDIP package of the X9315WPI.

Parameter Comparison

Engineering Selection Recommendations

The X9315WSIZ is the direct electrical equivalent to the X9315WPI and is the appropriate substitute when component availability is required. The X9315WSIZ is currently in active production status, whereas the X9315WPI is obsolete.

The X9315WSIZ carries ROHS3 compliance certification, meeting current environmental and regulatory standards. The X9315WPI is RoHS non-compliant.

The primary consideration for selection between these parts is the mounting technology requirement. The X9315WPI uses through-hole mounting (8-PDIP package), while the X9315WSIZ uses surface-mount technology (8-SOIC package). PCB layout and assembly process compatibility must be evaluated based on your manufacturing capabilities and design constraints.

Both parts share identical electrical specifications, functional parameters, and operating characteristics within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can X9315WSIZ directly replace X9315WPI in existing designs?

A: Electrical substitution is complete. The X9315WSIZ provides identical functionality, resistance value, tap configuration, interface protocol, and operating specifications. However, physical package differences require PCB redesign. The X9315WPI uses through-hole mounting (8-PDIP), while X9315WSIZ uses surface-mount technology (8-SOIC). Board layout and assembly process must be adapted accordingly.

Q: What are the key differences between these parts?

A: The parts are electrically and functionally identical. Differences are limited to: (1) Mounting type: through-hole versus surface-mount; (2) Package dimensions: 8-DIP (0.300", 7.62mm) versus 8-SOIC (0.154", 3.90mm Width); (3) Product status: obsolete versus active; (4) RoHS compliance: non-compliant versus ROHS3 compliant.

Q: Why is the X9315WPI listed as obsolete?

A: The X9315WPI is no longer in active production. The X9315WSIZ represents the current active equivalent in the XDCP™ series, utilizing modern surface-mount packaging and meeting current environmental compliance standards.

Q: Are there any compatibility concerns with the interface protocol?

A: No. Both parts implement identical Up/Down (U/D, INC, CS) interface control. Signal timing, pin configuration, and protocol behavior are equivalent.

Q: What is the impact of RoHS compliance differences?

A: The X9315WSIZ meets ROHS3 compliance standards, suitable for applications requiring environmental and regulatory adherence. The X9315WPI is RoHS non-compliant. Selection depends on your application's regulatory requirements and end-market standards.
