Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9241AUSIT2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 50kΩ
• Number of circuits: 4
• Number of taps: 64
• Interface protocol: I2C
• Memory type: Non-Volatile
• Supply voltage: 5V
• Package type: 20-SOIC
• Operating temperature range: -40°C to 85°C
• Taper characteristic: Linear

The X9241AUSIZT1 meets all substitution criteria as a direct equivalent. The primary distinction between these parts is packaging format (tape & reel versus bulk) and product status (active versus obsolete), with the substitute offering improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The X9241AUSIZT1 is the direct functional equivalent to the X9241AUSIT2 and is suitable for substitution in all applications requiring a 50kΩ digital potentiometer with I2C control and non-volatile memory in 20-SOIC packaging.

The X9241AUSIZT1 offers the following advantages:

• Active product status ensures continued manufacturer support and availability
• ROHS3 compliance versus non-compliant status of the original part
• Tape & reel packaging format suitable for automated assembly processes

Both parts share identical electrical specifications, operating parameters, and physical package dimensions, ensuring direct pin-for-pin and functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the X9241AUSIZT1 replace the X9241AUSIT2 in existing designs?

A: Yes. The X9241AUSIZT1 is electrically and functionally identical to the X9241AUSIT2 across all critical parameters including resistance value, circuit count, tap resolution, I2C interface, supply voltage, and operating temperature range. Pin configuration and package dimensions are identical.

Q: What is the difference between the two part numbers?

A: The primary differences are packaging format (tape & reel for X9241AUSIZT1 versus bulk for X9241AUSIT2), product status (active versus obsolete), and compliance certifications (ROHS3 compliant versus non-compliant). Electrical and functional specifications are identical.

Q: Are there any compatibility concerns when switching from X9241AUSIT2 to X9241AUSIZT1?

A: No compatibility concerns exist. Both parts are housed in the same 20-SOIC package with identical pinout, supply voltage requirements (5V), and I2C communication protocol. No circuit modifications or firmware changes are required.

Q: What is the moisture sensitivity difference between these parts?

A: The X9241AUSIT2 has MSL 1 (unlimited moisture exposure tolerance), while the X9241AUSIZT1 has MSL 3 (168 hours maximum exposure before reflow). This affects storage and handling procedures but does not impact electrical performance or long-term reliability after assembly.

Q: Is the X9241AUSIZT1 available in the same packaging format as the X9241AUSIT2?

A: The X9241AUSIZT1 is supplied in tape & reel format, which is standard for high-volume manufacturing. If bulk packaging is required, contact the manufacturer directly regarding alternative packaging options for this active product.
