Key Parameters

Substitute Part Grouping Explanation

The X9241AUSIZ qualifies as a direct substitute for the X9241AUSZ based on the following critical parameters:

• Identical resistance value: 50kΩ
• Matching circuit configuration: 4 circuits with 64 taps
• Same interface protocol: I2C with selectable address feature
• Identical non-volatile memory type
• Matching supply voltage: 5V
• Same package specification: 20-SOIC (0.295", 7.50mm Width)
• Identical mounting type: Surface Mount
• Linear taper configuration
• Equivalent wiper resistance: 40Ω typical

The X9241AUSIZ differs only in product status (Active vs. Obsolete), operating temperature range, and packaging format (Tube vs. unspecified), with no impact on core electrical functionality or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The X9241AUSIZ is the appropriate substitute for the obsolete X9241AUSZ. Both components maintain identical electrical specifications, mechanical compatibility, and regulatory compliance (ROHS3 Compliant, REACH Unaffected). The substitute offers the advantage of active product status, ensuring continued availability and manufacturing support. The extended operating temperature range of the X9241AUSIZ (-40°C ~ 85°C versus 0°C ~ 70°C) provides additional thermal margin for applications requiring broader environmental operation. Pin-for-pin compatibility and identical package dimensions ensure direct replacement without circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can the X9241AUSIZ be used as a direct replacement for the X9241AUSZ?
