Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IR3312STRR is determined by the following critical parameters:

• Output Configuration: High side, N-channel, 1:1 topology
• Package Compatibility: TO-263-5 / D2PAK surface mount form factor
• Current Rating: Minimum 14A output current capability
• On-Resistance: Electrical performance at 15mOhm typical
• Voltage Range: Load voltage support within or exceeding 6V ~ 28V specification
• Operating Temperature: Support for -40°C ~ 150°C junction temperature range
• Interface Type: Non-inverting on/off control

The BTS441TGATMA1 meets these substitution criteria. It maintains identical output configuration, package form factor, and operating temperature range. The substitute part exceeds the original specification in maximum output current (17A vs. 14A), load voltage range (4.75V ~ 43V vs. 6V ~ 28V), and on-resistance performance (15mOhm typical). The BTS441TGATMA1 is an active product with enhanced fault protection features and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The BTS441TGATMA1 is the qualified substitute for the obsolete IR3312STRR. Both components are manufactured by Infineon Technologies and share identical functional topology, package form factor, and thermal operating range.

The BTS441TGATMA1 offers the following advantages:

• Active Product Status: Ensures long-term availability and supply chain continuity
• Enhanced Regulatory Compliance: ROHS3 compliant versus RoHS non-compliant status of the original part
• Expanded Electrical Specifications: Higher maximum output current (17A) and wider load voltage range (4.75V ~ 43V) provide design margin
• Improved Protection Features: Includes over-voltage fault protection in addition to current limiting and over-temperature protection
• Identical Package and Pinout: Direct mechanical and electrical compatibility with existing PCB layouts

Selection of the BTS441TGATMA1 eliminates obsolescence risk while maintaining full functional compatibility with applications designed for the IR3312STRR.

Frequently Asked Questions (FAQ)

Q: Can the BTS441TGATMA1 be used as a direct replacement for the IR3312STRR without PCB modifications?

A: Yes. Both components use the TO-263-5 / D2PAK package with identical pinout and footprint. No PCB layout changes are required for mechanical or electrical integration.

Q: What are the key differences between these two parts?

A: The primary differences are product status and electrical specifications. The IR3312STRR is obsolete; the BTS441TGATMA1 is active. The BTS441TGATMA1 provides higher maximum output current (17A vs. 14A), wider load voltage range (4.75V ~ 43V vs. 6V ~ 28V), and additional over-voltage protection. Both maintain identical on-resistance (15mOhm typical) and operating temperature range (-40°C ~ 150°C).

Q: Are there any compliance or certification differences?

A: Yes. The BTS441TGATMA1 is ROHS3 compliant, while the IR3312STRR is RoHS non-compliant. Both parts are REACH unaffected and classified under ECCN EAR99. The BTS441TGATMA1 is part of the PROFET® series, indicating enhanced protection and reliability features.

Q: Will the BTS441TGATMA1 work in applications with load voltages below 6V?

A: Yes. The BTS441TGATMA1 supports load voltages as low as 4.75V, extending compatibility to applications that may operate below the original IR3312STRR specification of 6V minimum.

Q: Is the on-resistance performance equivalent between these parts?

A: Yes. Both components specify 15mOhm typical on-resistance, ensuring equivalent thermal and power dissipation characteristics in switching applications.

Q: What is the difference in fault protection between these parts?

A: The IR3312STRR provides adjustable current limiting and over-temperature protection. The BTS441TGATMA1 provides fixed current limiting, over-temperature protection, and additional over-voltage protection, offering more comprehensive fault coverage.
