X9241AMPIZ Digital Potentiometer Equivalent & Substitute Parts

Part Overview

The X9241AMPIZ is a 4-circuit digital potentiometer manufactured by Renesas Electronics Corporation, featuring selectable resistance values of 2kΩ, 10kΩ, 10kΩ, and 50kΩ with 64 taps and I2C interface control. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The part operates on 5V supply with non-volatile memory and through-hole mounting in a 20-DIP package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the X9241AMPIZ is determined by strict equivalence across the following critical parameters:

• Functional Parameters: Number of circuits (4), resistance values (2kΩ, 10kΩ, 10kΩ, 50kΩ), number of taps (64), and I2C interface protocol
• Electrical Specifications: 5V supply voltage, ±20% tolerance, ±300ppm/°C temperature coefficient, and 40Ω typical wiper resistance
• Memory Characteristics: Non-volatile memory type with selectable address features
• Environmental Compliance: ROHS3 compliance and REACH unaffected status
• Operating Conditions: -40°C to 85°C temperature range

The X9241AMSIZ qualifies as a direct functional equivalent, maintaining identical electrical and functional specifications while differing only in mounting technology and package form factor.

Parameter Comparison

Engineering Selection Recommendations

The X9241AMSIZ is the active equivalent for the obsolete X9241AMPIZ. Both parts maintain identical electrical specifications, functional parameters, and regulatory compliance status. The primary distinction is packaging technology: the X9241AMPIZ uses through-hole 20-DIP mounting, while the X9241AMSIZ employs surface-mount 20-SOIC technology.

Selection between these parts depends on PCB assembly requirements. Through-hole mounting (X9241AMPIZ) is suitable for manual assembly and breadboard prototyping but is obsolete. Surface-mount technology (X9241AMSIZ) is the current production standard and is recommended for new designs. The X9241AMSIZ carries active product status from Renesas Electronics Corporation, ensuring ongoing availability and support.

Both parts maintain ROHS3 compliance and REACH unaffected status. The moisture sensitivity level difference (MSL 1 versus MSL 3) reflects standard packaging variations and does not affect functional equivalence for typical operating environments.

Frequently Asked Questions (FAQ)

Q: Can the X9241AMSIZ directly replace the X9241AMPIZ in existing designs?

A: Electrical and functional replacement is direct. PCB layout modification is required due to package format change from 20-DIP through-hole to 20-SOIC surface-mount. Pin assignments and electrical characteristics remain identical.

Q: What are the key parameters that define substitution eligibility?

A: Substitution requires matching: number of circuits (4), resistance values (2kΩ, 10kΩ, 10kΩ, 50kΩ), number of taps (64), I2C interface, 5V supply voltage, non-volatile memory, ±20% tolerance, ±300ppm/°C temperature coefficient, and -40°C to 85°C operating range.

Q: Why is the X9241AMPIZ classified as obsolete?

A: The X9241AMPIZ is obsolete due to industry transition from through-hole to surface-mount packaging technology. The X9241AMSIZ represents the current production equivalent in surface-mount form factor.

Q: Are there differences in moisture sensitivity between these parts?

A: The X9241AMPIZ has MSL 1 (unlimited moisture sensitivity level), while the X9241AMSIZ has MSL 3 (168 hours). This reflects standard packaging differences and does not affect functional performance in typical operating environments.

Q: Do both parts support I2C communication identically?

A: Yes. Both parts implement identical I2C interface protocols with selectable address features and non-volatile memory for configuration storage.

Q: What is the inventory status for these parts?

A: X9241AMPIZ: 1090 pieces in stock (obsolete status). X9241AMSIZ: 1235 pieces in stock (active status).
