Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9241AWS is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ
• Circuit count: 4 independent potentiometer circuits
• Tap resolution: 64 taps
• Interface protocol: I2C
• Memory architecture: Non-volatile storage
• Supply voltage: 5V operation
• Package format: 20-SOIC surface mount
• Electrical characteristics: Linear taper, ±20% tolerance, ±300ppm/°C temperature coefficient, 40Ω typical wiper resistance

The X9241AWSZ meets all substitution criteria as a direct equivalent, differing only in packaging format (tube vs. unspecified for the main part) and product lifecycle status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

The X9241AWSZ is the direct functional equivalent to the X9241AWS. Selection between these parts should be based on the following criteria:

X9241AWS is suitable only for legacy system maintenance where existing inventory is available or where RoHS non-compliance is acceptable for the application.

X9241AWSZ is the recommended selection for new designs and ongoing production. This part maintains identical electrical and functional specifications while offering active product status from the manufacturer. The X9241AWSZ provides ROHS3 compliance, meeting modern regulatory requirements for electronic components in most markets. The increased moisture sensitivity level (MSL 3 vs. MSL 1) requires standard handling procedures during storage and assembly but does not affect operational performance.

Frequently Asked Questions (FAQ)

Q: Can X9241AWSZ directly replace X9241AWS in existing designs?

A: Yes. The X9241AWSZ is electrically and functionally identical to the X9241AWS. All electrical parameters, interface specifications, and package dimensions are equivalent. The parts are pin-compatible and require no circuit modifications.

Q: What is the difference between X9241AWS and X9241AWSZ?

A: The primary differences are product lifecycle status and regulatory compliance. X9241AWSZ is an active product with ROHS3 compliance, while X9241AWS is obsolete and RoHS non-compliant. Packaging format differs (tube for X9241AWSZ). Moisture sensitivity levels differ (MSL 3 vs. MSL 1), requiring standard moisture control during handling for the X9241AWSZ.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical performance across all electrical and functional parameters, including resistance value, tap resolution, I2C interface operation, temperature coefficient, and wiper resistance.

Q: What does MSL 3 (168 Hours) mean for the X9241AWSZ?

A: MSL 3 indicates the component can be exposed to ambient conditions of 30°C and 85% relative humidity for a maximum of 168 hours before soldering. Standard moisture control procedures during storage and assembly are required. This does not affect the component's operational performance after assembly.

Q: Is the 20-SOIC package identical for both parts?

A: Yes. Both parts use the 20-SOIC package with identical dimensions (0.295", 7.50mm width). PCB footprints and assembly processes are interchangeable.

Q: Which part should be specified for new designs?

A: X9241AWSZ should be specified for new designs. It provides active manufacturer support, ROHS3 compliance, and ensures long-term component availability.
