X9241AMV Equivalent & Substitute Parts

Part Overview

The X9241AMV is a digital potentiometer manufactured by Renesas Electronics Corporation, featuring four independent circuits with 64 taps each, supporting resistance values of 2kΩ, 10kΩ, 10kΩ, and 50kΩ. The device operates via I2C interface with non-volatile memory and 5V supply voltage. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the X9241AMV is determined by the following critical parameters: number of circuits (4), number of taps (64), interface type (I2C), memory type (non-volatile), package format (20-TSSOP), and mounting type (surface mount).

Direct Equivalent: X9241AMVZ maintains identical electrical specifications and circuit configuration as the X9241AMV, differing only in packaging format (tube vs. unspecified) and product status (active vs. obsolete). This part is the primary direct substitute.

Similar Substitute: CAT5241YI-10-T2 (onsemi) provides a 4-circuit, 64-tap digital potentiometer in 20-TSSOP package with non-volatile memory. However, this part features a single 10kΩ resistance value rather than the multi-value configuration of the X9241AMV, and operates across a wider supply voltage range (2.5V to 6V) with extended operating temperature (-40°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

X9241AMVZ is the recommended direct substitute for the X9241AMV. Both parts share identical electrical specifications, circuit configuration, and operating parameters. X9241AMVZ holds active product status and maintains ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete X9241AMV.

CAT5241YI-10-T2 serves as an alternative only when circuit designs can accommodate a single 10kΩ resistance value across all four channels. This onsemi device provides extended operating temperature range and wider supply voltage tolerance, suitable for applications requiring enhanced environmental performance. However, the absence of 2kΩ and 50kΩ resistance options limits its applicability to designs utilizing only 10kΩ potentiometer circuits.

Frequently Asked Questions (FAQ)

Q: Can X9241AMVZ directly replace X9241AMV without circuit modification? A: Yes. X9241AMVZ provides identical electrical and functional specifications, including resistance values, tap count, I2C interface, and operating parameters. No circuit redesign is required.

Q: What are the limitations of using CAT5241YI-10-T2 as a substitute? A: CAT5241YI-10-T2 provides only 10kΩ resistance across all four circuits. Applications requiring 2kΩ or 50kΩ potentiometer values cannot use this part without circuit redesign. Additionally, the extended operating temperature range (-40°C to 85°C) may introduce different thermal characteristics compared to the X9241AMV specification (0°C to 70°C).

Q: Are all substitute parts available in the same 20-TSSOP package? A: Yes. X9241AMVZ and CAT5241YI-10-T2 are both supplied in 20-TSSOP (0.173", 4.40mm width) surface mount packages, ensuring mechanical compatibility with existing PCB layouts.

Q: What is the difference between X9241AMV and X9241AMVZ packaging? A: X9241AMV packaging format is unspecified, while X9241AMVZ is supplied in tube packaging. Both parts use identical 20-TSSOP surface mount packages.

Q: Are there compliance differences between the substitute parts? A: X9241AMV is RoHS non-compliant. X9241AMVZ and CAT5241YI-10-T2 are both ROHS3 compliant. For applications requiring RoHS compliance, X9241AMVZ is the appropriate selection.
