X9315WSIT1 Equivalent & Substitute Parts

Part Overview

The X9315WSIT1 is a digital potentiometer manufactured by Renesas Electronics Corporation, part of the XDCP™ series. This 10kΩ, 32-tap device features a non-volatile memory interface with Up/Down (U/D, INC, CS) control, housed in an 8-SOIC surface mount package. The component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the X9315WSIT1 is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ
• Number of taps: 32
• Interface protocol: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage: 5V
• Package type: 8-SOIC
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface Mount

Two substitute parts meet these criteria:

X9315WSIZT1 — Direct manufacturer equivalent with identical electrical and mechanical specifications. Differs only in packaging format (Tape & Reel) and product status (Active vs. Obsolete).

X9313WSIZT1 — Parametric equivalent sharing all core functional parameters. Differs in wiper resistance (40Ω vs. 200Ω) and base product number (X9313 vs. X9315), but maintains full compatibility with the specified interface and control protocol.

Parameter Comparison

Engineering Selection Recommendations

X9315WSIZT1 is the primary substitute for direct replacement. It maintains identical electrical specifications and package configuration while offering Active product status and ROHS3 compliance. The only distinction is packaging format (Tape & Reel vs. bulk), which does not affect electrical performance or PCB integration.

X9313WSIZT1 serves as a parametric equivalent when X9315WSIZT1 is unavailable. While wiper resistance differs (40Ω vs. 200Ω), this parameter does not affect the core potentiometer function or interface compatibility. The X9313WSIZT1 also provides Active status and ROHS3 compliance, with superior inventory availability (1732 units).

Both substitutes are manufactured by Renesas Electronics Corporation within the XDCP™ series and maintain full compatibility with the original X9315WSIT1 interface protocol and control methodology.

Frequently Asked Questions (FAQ)

Q: Can X9315WSIZT1 be used as a direct replacement for X9315WSIT1?

A: Yes. X9315WSIZT1 is electrically and mechanically identical to X9315WSIT1. The only difference is packaging format (Tape & Reel vs. standard packaging). Both devices share identical resistance, tap count, interface protocol, supply voltage, and package dimensions.

Q: What is the difference between X9315WSIZT1 and X9313WSIZT1?

A: Both are 10kΩ, 32-tap digital potentiometers with identical interface and control protocols. The primary difference is wiper resistance: X9315WSIZT1 has 200Ω typical wiper resistance, while X9313WSIZT1 has 40Ω. This parameter does not affect substitutability for the X9315WSIT1 application.

Q: Why is X9315WSIT1 marked as obsolete?

A: X9315WSIT1 is classified as obsolete by Renesas Electronics Corporation. X9315WSIZT1 and X9313WSIZT1 are active alternatives that provide continued design support and production availability.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both X9315WSIZT1 and X9313WSIZT1 are ROHS3 compliant. The original X9315WSIT1 is RoHS non-compliant.

Q: Do the substitute parts fit the same PCB footprint?

A: Yes. All three parts use the 8-SOIC package with identical dimensions (0.154", 3.90mm Width). PCB layout and footprint remain unchanged.

Q: What is the operating temperature range for these devices?

A: All three parts operate across -40°C to 85°C, maintaining full specification compliance throughout this range.
