ISL95310WIU10Z Equivalent & Substitute Parts

Part Overview

The ISL95310WIU10Z is a digital potentiometer manufactured by Renesas Electronics Corporation, featuring 10kΩ resistance with 128 taps and Up/Down (U/D, INC, CS) interface control. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates across a 2.7V to 5.5V supply range and is housed in a 10-MSOP surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ISL95310WIU10Z is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 10kΩ (exact match required for circuit function)
• Number of taps: 128 (resolution requirement)
• Interface type: Up/Down (U/D, INC, CS) control signals
• Package type: 10-MSOP surface mount
• Supply voltage range: 2.7V ~ 5.5V (minimum overlap required)
• Memory type: Non-Volatile
• Operating temperature range: -40°C ~ 85°C (minimum overlap required)

Substitute Categories:

Category 1: Direct Equivalent (Same Resistance Value)

• ISL95310UIU10Z (Renesas, 50kΩ variant - resistance mismatch, not suitable as direct substitute)
• CAT5133ZI-10-GT3 (onsemi, 10kΩ - matches primary resistance requirement)

Category 2: Same Base Series, Different Resistance

• ISL95310UIU10Z (Renesas XDCP™ series, 50kΩ - different resistance value)

Parameter Comparison

Engineering Selection Recommendations

ISL95310UIU10Z (Renesas Electronics) This part shares the same manufacturer, series (XDCP™), package, and interface as the main part. However, the 50kΩ resistance value differs from the 10kΩ requirement of ISL95310WIU10Z. This part is not a direct substitute due to resistance mismatch. Selection is appropriate only if circuit design permits 50kΩ operation. Product status is Active, providing long-term availability and supply continuity.

CAT5133ZI-10-GT3 (onsemi) This part matches the critical resistance value (10kΩ), tap count (128), package (10-MSOP), and supply voltage range of the main part. The interface differs slightly (Up/Down with U/D and CS, without INC signal). Temperature coefficient is higher (±300ppm/°C versus ±45ppm/°C), and wiper resistance is higher (110Ω versus 70Ω). Moisture sensitivity is superior (MSL 1 versus MSL 2). Both parts are obsolete. This part is the closest functional equivalent for 10kΩ applications.

Frequently Asked Questions (FAQ)

Q: Can ISL95310UIU10Z replace ISL95310WIU10Z directly? A: No. While both are Renesas XDCP™ series digital potentiometers in 10-MSOP packages with identical interface and supply voltage specifications, the ISL95310UIU10Z has 50kΩ resistance versus the 10kΩ requirement of ISL95310WIU10Z. Direct substitution is not possible without circuit redesign.

Q: Is CAT5133ZI-10-GT3 a suitable replacement for ISL95310WIU10Z? A: CAT5133ZI-10-GT3 matches the 10kΩ resistance, 128-tap resolution, 10-MSOP package, and operating temperature range. The interface lacks the INC signal (includes only U/D and CS). Temperature coefficient and wiper resistance differ. Compatibility depends on whether the INC signal is required in the application and whether the higher temperature coefficient and wiper resistance are acceptable.

Q: What is the impact of different temperature coefficients? A: ISL95310WIU10Z has ±45ppm/°C while CAT5133ZI-10-GT3 has ±300ppm/°C. Higher temperature coefficient means greater resistance variation across the operating temperature range. For precision applications, this difference may be significant.

Q: Are all substitute parts RoHS3 compliant? A: Yes. ISL95310WIU10Z, ISL95310UIU10Z, and CAT5133ZI-10-GT3 are all ROHS3 compliant.

Q: What is the difference in moisture sensitivity between these parts? A: ISL95310WIU10Z and ISL95310UIU10Z have MSL 2 (1 Year), while CAT5133ZI-10-GT3 has MSL 1 (Unlimited). Lower MSL rating indicates better moisture resistance and longer shelf life without baking requirements.

Q: Can I use ISL95310UIU10Z if I add external resistors to adjust the resistance value? A: External resistor networks cannot modify the internal potentiometer resistance value. The 50kΩ internal resistance of ISL95310UIU10Z cannot be converted to 10kΩ through external components. A different part with 10kΩ internal resistance is required.
