Substitute Part Grouping Explanation

Substitution eligibility for the BTS452TT is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Infineon Technologies miniPROFET® series
• Electrical Specifications: 1.8A maximum output current, 150mOhm typical on-resistance, 6V to 52V load voltage range
• Output Configuration: High-side N-Channel switch with 1:1 input-to-output ratio
• Package: TO-252-5 (DPAK with 4 leads plus tab)
• Thermal and Environmental: -40°C to 150°C operating range, automotive grade with AEC-Q100 qualification
• Protection Features: Current limiting, over-temperature, and over-voltage protection with auto-restart capability

The BTS452TATMA1 meets all these criteria and is classified as the manufacturer-recommended substitute. This part maintains identical electrical performance and mechanical compatibility while offering improved product status and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The BTS452TATMA1 is the direct equivalent substitute for the BTS452TT. Both components share identical electrical specifications, thermal ratings, package configuration, and protective features. The primary distinction lies in product lifecycle status and regulatory compliance.

The BTS452TT is classified as Obsolete, indicating discontinued manufacturing and limited availability. The BTS452TATMA1 maintains Active product status with current manufacturing support and significantly higher inventory availability (6950 pieces versus 888 pieces).

From a compliance perspective, the BTS452TATMA1 achieves ROHS3 compliance, whereas the BTS452TT is RoHS non-compliant. Both parts maintain REACH Unaffected status and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

For new designs or ongoing production requiring this power switch topology, the BTS452TATMA1 is the appropriate selection. For legacy systems currently using BTS452TT, direct substitution with BTS452TATMA1 is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Are BTS452TT and BTS452TATMA1 pin-compatible?

A: Yes. Both components use the TO-252-5 package (DPAK with 4 leads plus tab). Pin configuration and lead spacing are identical, enabling direct board-level substitution without layout modification.

Q: What is the difference between BTS452TT and BTS452TATMA1?

A: The components are electrically and functionally equivalent. The primary differences are product status (Obsolete versus Active), RoHS compliance (non-compliant versus ROHS3 compliant), and inventory availability. The BTS452TATMA1 is the current production equivalent.

Q: Can BTS452TATMA1 replace BTS452TT in existing applications?

A: Yes. The BTS452TATMA1 maintains identical electrical specifications, current ratings, voltage ranges, thermal characteristics, and protective features. Direct substitution is valid for all applications currently using BTS452TT.

Q: What packaging options are available for BTS452TATMA1?

A: The BTS452TATMA1 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Both formats contain the same component in the TO-252-5 package configuration.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both components operate across the identical temperature range (-40°C to 150°C junction temperature) and carry automotive-grade qualification with AEC-Q100 certification.

Q: What protection features are included in both parts?

A: Both BTS452TT and BTS452TATMA1 include current limiting (fixed threshold), over-temperature protection, and over-voltage protection. Both feature auto-restart capability following fault conditions.
