IR6220STRL Equivalent & Substitute Parts

Part Overview

The IR6220STRL is a Power Management IC (PMIC) classified as a power switch/driver with 1:1 N-Channel configuration, rated for 10A output current in a D2PAK (TO-263-5) surface mount package. This component is designed for high-side switching applications with load voltages ranging from 5V to 35V and features integrated current limiting and over-temperature protection.

The IR6220STRL has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IR6220STRL are identified based on the following critical parameters that determine functional compatibility:

• Output Configuration: High Side, N-Channel, 1:1 ratio
• Package / Case: TO-263-5 (D2PAK) mechanical compatibility
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Interface Type: On/Off control with Non-Inverting input
• Fault Protection: Current Limiting and Over Temperature capability

The BTS441RGATMA1 and BTS441TGATMA1 satisfy these core substitution criteria. Both parts maintain identical output configuration, package form factor, and operating temperature specifications. The primary differences between these substitutes and the original part relate to enhanced electrical performance (higher current rating and lower on-resistance) and improved fault protection features, which provide superior capability within the same mechanical and thermal envelope.

Parameter Comparison

Engineering Selection Recommendations

Both BTS441RGATMA1 and BTS441TGATMA1 are active, production-qualified alternatives to the obsolete IR6220STRL. The selection between these two substitute parts depends on packaging and supply chain requirements:

• BTS441RGATMA1: Supplied in Cut Tape (CT) & Digi-Reel® packaging format
• BTS441TGATMA1: Supplied in Tape & Reel (TR) packaging format

Both substitutes are ROHS3 compliant, addressing regulatory requirements that the original IR6220STRL does not meet. The electrical performance of both substitutes exceeds the original part specification, with higher current capacity (17A vs. 10A) and significantly lower on-resistance (15mOhm vs. 80mOhm), while maintaining full mechanical and thermal compatibility through identical TO-263-5 packaging and -40°C to 150°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can BTS441RGATMA1 and BTS441TGATMA1 be used interchangeably with IR6220STRL?

A: Yes. Both substitute parts maintain identical output configuration (High Side N-Channel 1:1), package form factor (TO-263-5 D2PAK), and operating temperature range (-40°C ~ 150°C TJ). The substitutes provide enhanced electrical performance and are pin-compatible for direct replacement.

Q: What is the difference between BTS441RGATMA1 and BTS441TGATMA1?

A: The functional electrical specifications are identical. The difference is packaging format: BTS441RGATMA1 is supplied in Cut Tape (CT) & Digi-Reel® format, while BTS441TGATMA1 is supplied in Tape & Reel (TR) format. Selection depends on assembly line requirements and inventory management practices.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both BTS441RGATMA1 and BTS441TGATMA1 are ROHS3 compliant, whereas the original IR6220STRL is RoHS non-compliant. This compliance improvement may be required for new designs or updated manufacturing standards.

Q: What are the key electrical improvements in the substitute parts?

A: The substitute parts offer higher maximum output current (17A vs. 10A) and significantly lower on-resistance (15mOhm vs. 80mOhm). The load voltage range is also extended (4.75V ~ 43V vs. 5V ~ 35V). These improvements provide better thermal performance and lower power dissipation in the same package.

Q: Are there any compatibility concerns with PCB layouts designed for IR6220STRL?

A: No. Both substitute parts use the identical TO-263-5 (D2PAK) package with the same pin configuration and mechanical footprint. Existing PCB layouts require no modification.
