X9C102SIZ Digital Potentiometer Equivalent & Substitute Parts

Part Overview

The X9C102SIZ is a digital potentiometer manufactured by Renesas Electronics Corporation, designed for data acquisition applications requiring programmable resistance adjustment. This 1kΩ device features 100 taps with up/down control interface and non-volatile memory, enabling persistent resistance settings across power cycles. The part is currently in active production status with robust inventory availability (3092 pcs in stock). Substitute parts become necessary when addressing supply chain constraints, packaging preferences, or specific application requirements that align with equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9C102SIZ is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1kΩ
• Number of taps: 100
• Number of circuits: 1
• Interface protocol: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Package type: 8-SOIC
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 85°C minimum
• Taper characteristic: Linear

Allowable Variation Parameters:

• Voltage supply range (must encompass 5V operation)
• Temperature coefficient (within application tolerance)
• Wiper resistance (within functional limits)
• Packaging format (Tube vs. Cut Tape)
• Product status (Active or Obsolete, subject to availability)

The CAT5113VI-01-GT3 from onsemi meets all mandatory matching criteria while providing a wider supply voltage range (2.5V ~ 6V) and improved temperature coefficient performance (300ppm/°C vs. ±600ppm/°C).

Engineering Selection Recommendations

X9C102SIZ (Primary Selection): Select this part for new designs and applications requiring long-term supply assurance. Active product status ensures continued manufacturing support, availability, and potential design improvements. Renesas Electronics Corporation maintains robust distribution channels and production capacity. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) support standard manufacturing and storage protocols.

CAT5113VI-01-GT3 (Substitute Selection): This part functions as an electrical and mechanical equivalent for existing designs or applications where supply of the primary part is constrained. The wider supply voltage range (2.5V ~ 6V) provides operational flexibility beyond the X9C102SIZ's 5V specification. The improved temperature coefficient (300ppm/°C) delivers superior stability in temperature-sensitive applications. Note that obsolete product status indicates onsemi has discontinued active production; substitute selection should account for finite inventory availability (5087 pcs reported in stock). Cut Tape packaging differs from Tube format; verify compatibility with assembly processes.

Both parts maintain identical functional parameters across resistance value, tap count, interface protocol, memory type, package footprint, and operating temperature range, ensuring direct functional interchangeability within these specified boundaries.

Frequently Asked Questions (FAQ)

Q: Can the CAT5113VI-01-GT3 directly replace the X9C102SIZ in existing PCB designs?

A: Yes, direct replacement is possible. Both parts share identical 8-SOIC package dimensions (0.154", 3.90mm width), pinout configuration, and interface protocol (Up/Down with U/D, INC, CS control lines). No PCB layout modifications are required. Verify that your application's supply voltage remains within the CAT5113VI-01-GT3 operating range of 2.5V ~ 6V.

Q: What is the significance of the different wiper resistance specifications?

A: The X9C102SIZ specifies typical wiper resistance of 40Ω, while the CAT5113VI-01-GT3 specifies maximum wiper resistance of 1000Ω. Wiper resistance affects signal integrity in high-impedance measurement circuits and loading characteristics. Applications sensitive to wiper resistance should prioritize the X9C102SIZ specification. For general potentiometer applications, both values remain within acceptable operational limits.

Q: Why does the CAT5113VI-01-GT3 show obsolete status despite available inventory?

A: Obsolete status indicates onsemi has discontinued active production and design support for this part. Existing inventory (5087 pcs reported) represents remaining stock from final production runs. While currently available, long-term supply cannot be assured. For applications requiring extended production lifecycles, the active-status X9C102SIZ is the recommended primary selection.

Q: Are there packaging format differences between these parts?

A: Yes. The X9C102SIZ is supplied in Tube packaging, while the CAT5113VI-01-GT3 is supplied in Cut Tape (CT) format. Tube packaging is typical for manual assembly and lower-volume applications. Cut Tape format is standard for automated pick-and-place assembly. Verify compatibility with your manufacturing process before substitution.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8542.39.0001. Both maintain MSL 1 (Unlimited) moisture sensitivity level, supporting standard storage and handling protocols without special environmental controls.

Q: What is the temperature coefficient difference, and does it matter for my application?

A: The X9C102SIZ specifies ±600ppm/°C temperature coefficient, while the CAT5113VI-01-GT3 specifies 300ppm/°C. Lower temperature coefficient indicates better resistance stability across temperature variations. For precision applications operating across the full -40°C ~ 85°C range, the CAT5113VI-01-GT3 provides superior performance. For general-purpose applications, both coefficients are acceptable.
