IXD3221A095MR Equivalent & Substitute Parts

Part Overview

The IXD3221A095MR is a buck regulator positive output step-down DC-DC controller IC manufactured by Zilog in SOT-25 packaging. This device functions as a transistor driver for step-down topology applications with a single output phase and 500kHz switching frequency. The part is active and in production with 1009 units currently in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers offer equivalent electrical and mechanical specifications, or when design flexibility requires selection from multiple qualified sources. All substitute parts listed maintain identical electrical parameters and package compatibility with the original IXD3221A095MR.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IXD3221A095MR are qualified based on the following critical parameters that must remain constant:

• Topology: Buck (step-down)
• Output Configuration: Positive
• Output Type: Transistor Driver
• Number of Outputs: 1
• Output Phases: 1
• Voltage Supply Range: 2.8V ~ 16V
• Duty Cycle (Max): 100%
• Synchronous Rectifier: No
• Clock Sync: No
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: SC-74A, SOT-753
• RoHS Status: ROHS3 Compliant

• XC9220B095MR-G (500kHz switching frequency)
• XC9220C095MR-G (500kHz switching frequency)
• XC9220C09AMR-G (1MHz switching frequency)
• XC9220D093MR-G (300kHz switching frequency)
• XC9220D095MR-G (500kHz switching frequency)
• XC9221A093MR-G (300kHz switching frequency)
• XC9221A095MR-G (500kHz switching frequency)
• XC9221A09AMR-G (1MHz switching frequency)

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and REACH unaffected status, matching the regulatory and environmental requirements of the IXD3221A095MR. Selection among substitute parts should be based on:

1. Switching frequency requirements: Parts are available at 300kHz, 500kHz, and 1MHz. The IXD3221A095MR operates at 500kHz; XC9220B095MR-G, XC9220C095MR-G, XC9220D095MR-G, and XC9221A095MR-G provide identical switching frequency.

2. Inventory availability: XC9221A095MR-G offers the highest stock level at 19049 units, providing supply chain flexibility.

3. Manufacturer qualification: All substitute parts are from Torex Semiconductor Ltd and maintain identical electrical specifications, package configuration, and thermal operating range.

4. Control feature consistency: All parts include Enable and Soft Start control features as specified in the original design.

Frequently Asked Questions (FAQ)

Q: Can XC9220 series parts substitute for the IXD3221A095MR?

A: Yes. XC9220A093MR-G, XC9220A09AMR-G, XC9220B095MR-G, XC9220C095MR-G, XC9220C09AMR-G, XC9220D093MR-G, and XC9220D095MR-G are all qualified substitutes. They maintain identical topology, output configuration, voltage supply range, duty cycle, operating temperature, and package specifications.

Q: Can XC9221 series parts substitute for the IXD3221A095MR?

A: Yes. XC9221A093MR-G, XC9221A095MR-G, and XC9221A09AMR-G are all qualified substitutes with identical electrical and mechanical parameters.

Q: What is the difference between 300kHz, 500kHz, and 1MHz variants?

A: The switching frequency differs among substitute parts. The IXD3221A095MR operates at 500kHz. Substitute parts at 500kHz (XC9220B095MR-G, XC9220C095MR-G, XC9220D095MR-G, XC9221A095MR-G) provide direct frequency matching. Parts at 300kHz or 1MHz maintain all other electrical specifications but operate at different switching frequencies.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use SC-74A, SOT-753 package configuration with SOT-25-5 supplier device package, ensuring mechanical compatibility with the IXD3221A095MR.
