IR2238Q Equivalent & Substitute Parts

Part Overview

The IR2238Q is a motor driver integrated circuit manufactured by Infineon Technologies, designed for AC and synchronous motor control applications. It functions as a commutation and direction management controller with pre-driver capability for half-bridge IGBT configurations. The device operates within a 12.5V to 20V supply voltage range and is housed in a 64-MQFP surface mount package.

The IR2238Q holds an obsolete product status, making it necessary to identify equivalent substitute components for new designs and ongoing production requirements. Locating compatible alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the IR2238Q are identified based on strict electrical and mechanical parameter alignment. The primary substitute, IR2238QPBF, maintains functional equivalence through identical specifications across all critical parameters: motor control function, voltage supply range, operating temperature range, output configuration, interface type, and package form factor.

The substitution logic is based on the following key parameters:

• Motor Type Support (AC, Synchronous)
• Commutation and Direction Management Function
• Pre-Driver Half Bridge (3) Output Configuration
• Parallel Interface Architecture
• 12.5V ~ 20V Supply Voltage Range
• -20°C ~ 115°C Operating Temperature Range
• 64-BQFP Package / 64-MQFP (20x14) Physical Form Factor
• Surface Mount Mounting Type

Parameter Comparison

Engineering Selection Recommendations

The IR2238QPBF serves as the direct substitute for the IR2238Q. Both components are manufactured by Infineon Technologies and maintain identical electrical and mechanical specifications. The primary distinction lies in product lifecycle status: the IR2238Q is obsolete, while the IR2238QPBF carries a Last Time Buy designation, indicating limited future availability.

For new designs and production continuity, IR2238QPBF is the appropriate selection. Both components comply with REACH regulations and carry EAR99 export classification. The packaging difference (tray for IR2238QPBF versus unspecified for IR2238Q) does not affect functional compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can IR2238QPBF directly replace IR2238Q in existing designs?

A: Yes. Both components share identical electrical specifications, output configuration, interface type, voltage supply range, operating temperature range, and package form factor. Direct substitution is functionally compatible.

Q: What is the significance of the product status difference?

A: The IR2238Q is obsolete and no longer manufactured. The IR2238QPBF is in Last Time Buy status, meaning Infineon will produce limited quantities before discontinuation. For ongoing production, IR2238QPBF should be selected while availability permits.

Q: Are there packaging considerations for substitution?

A: Both components use the 64-MQFP (20x14) physical package and 64-BQFP case designation. The IR2238QPBF is supplied in tray packaging. No PCB layout or footprint modifications are required for substitution.

Q: Do compliance certifications differ between the two parts?

A: No. Both components are REACH Unaffected and carry EAR99 export classification. Regulatory compliance is equivalent.

Q: What is the moisture sensitivity level difference?

A: The IR2238Q has MSL 1 (Unlimited), while IR2238QPBF has MSL 3 (168 Hours). This affects storage and handling procedures. IR2238QPBF requires more stringent moisture control during storage and assembly processes.
