Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL90810UIU8Z is determined by the following critical parameters:

• Resistance value: 50kΩ (exact match required)
• Number of taps: 256 (exact match required)
• Interface protocol: I2C (exact match required)
• Number of circuits: 1 (exact match required)
• Supply voltage range: 2.7V ~ 5.5V (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Package type: 8-MSOP (exact match required)
• Mounting type: Surface Mount (exact match required)

The ISL95810UIU8Z meets all substitution criteria as an active equivalent part from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The ISL95810UIU8Z is the direct active equivalent for the obsolete ISL90810UIU8Z. Both parts maintain identical electrical specifications across all critical parameters including resistance value, tap count, interface protocol, supply voltage, operating temperature range, and package configuration. Both components satisfy ROHS3 compliance and REACH requirements.

The primary distinction between these parts is product status: ISL90810UIU8Z is obsolete while ISL95810UIU8Z is active. Additionally, ISL95810UIU8Z features non-volatile memory compared to the volatile memory of the main part, and exhibits a slightly higher temperature coefficient of ±45ppm/°C versus ±35ppm/°C. These differences do not affect functional substitution in applications where the electrical and mechanical interfaces are identical.

Frequently Asked Questions (FAQ)

Q: Can ISL95810UIU8Z directly replace ISL90810UIU8Z in existing designs?

A: Yes. Both parts share identical pin configurations, package dimensions, electrical operating ranges, and interface protocols. No circuit modifications are required for substitution.

Q: What is the significance of the memory type difference?

A: ISL90810UIU8Z uses volatile memory, while ISL95810UIU8Z uses non-volatile memory. This means ISL95810UIU8Z retains potentiometer settings after power loss, whereas ISL90810UIU8Z does not. Application requirements determine whether this difference is relevant.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in 8-MSOP surface mount packages with identical dimensions (0.118", 3.00mm width). Packaging is functionally equivalent.

Q: Why is ISL90810UIU8Z obsolete?

A: The ISL90810UIU8Z has been discontinued by Renesas Electronics Corporation. ISL95810UIU8Z is the active production equivalent.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both ISL90810UIU8Z and ISL95810UIU8Z are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the temperature coefficient difference impact?

A: ISL95810UIU8Z has a temperature coefficient of ±45ppm/°C compared to ±35ppm/°C for ISL90810UIU8Z. This represents a 10ppm/°C difference in resistance drift over temperature. Application precision requirements determine significance.
