Key Parameters

Substitute Part Grouping Explanation

Substitution of the BD3572FP-E2 is determined by the following critical parameters:

• Package Compatibility: Both devices must use TO-252-5 (DPAK with 4 Leads + Tab) to ensure direct PCB footprint compatibility
• Output Configuration & Type: Positive adjustable output is required for functional equivalence
• Voltage Range: Input maximum of 36V or higher, output adjustable range covering 2.8V to 12V minimum
• Current Rating: Output current of 400mA or higher to meet or exceed the 500mA requirement
• Control Features: Enable function must be present
• Protection Features: Over Current and Over Temperature protection are baseline requirements
• Operating Temperature: Range must encompass -40°C to 125°C minimum
• Compliance: RoHS3 compliance and MSL 1 rating required

The TLE42764DVATMA1 from Infineon Technologies meets these substitution criteria within the allowed electrical and mechanical parameters for this product category.

Engineering Selection Recommendations

The TLE42764DVATMA1 is a direct substitute for the BD3572FP-E2 based on the following factors:

• Package Compatibility: Both devices use identical TO-252-5 DPAK packaging, enabling direct PCB replacement without layout modifications
• Functional Equivalence: Both are positive adjustable linear regulators with single output and Enable control feature
• Compliance Status: Both devices are RoHS3 compliant with MSL 1 rating and REACH unaffected status, meeting regulatory requirements
• Product Status Consideration: The BD3572FP-E2 is marked as not for new designs, while the TLE42764DVATMA1 is active, making it suitable for ongoing production and new applications
• Automotive Qualification: The TLE42764DVATMA1 carries AEC-Q100 qualification and automotive grade designation, providing additional reliability assurance for demanding applications
• Enhanced Protection: The substitute includes reverse polarity and short circuit protection in addition to the baseline over current and over temperature protection

Frequently Asked Questions (FAQ)

Q: Can the TLE42764DVATMA1 directly replace the BD3572FP-E2 on existing PCBs?

A: Yes. Both devices use the TO-252-5 DPAK package with identical pinout and lead configuration, allowing direct PCB replacement without layout changes.

Q: What is the impact of the 400mA output current on the TLE42764DVATMA1 versus the 500mA of the BD3572FP-E2?

A: The substitute provides 400mA maximum output current compared to 500mA on the original. Applications requiring output current above 400mA cannot use this substitute and require alternative solutions.

Q: Are there differences in voltage output range between these devices?

A: The TLE42764DVATMA1 offers a wider adjustable output range (2.5V to 20V) compared to the BD3572FP-E2 (2.8V to 12V). Both ranges overlap sufficiently for most adjustable regulator applications within the original device's specified limits.

Q: Does the higher operating temperature range of the TLE42764DVATMA1 affect compatibility?

A: The TLE42764DVATMA1 operates to 150°C versus 125°C for the BD3572FP-E2. This extended range does not create compatibility issues and provides additional thermal margin for demanding applications.

Q: What additional protection features does the substitute provide?

A: The TLE42764DVATMA1 includes reverse polarity and short circuit protection beyond the over current and over temperature protection present in both devices. These additional protections enhance system robustness without affecting pin compatibility.

Q: Are there supply chain considerations when switching to the TLE42764DVATMA1?

A: The TLE42764DVATMA1 is marked as active product status with significantly higher inventory availability (17,500 pcs) compared to the BD3572FP-E2 (865 pcs), indicating better long-term supply continuity.

Q: What is the packaging difference between Tape & Reel and Cut Tape & Digi-Reel?

A: Both are surface mount delivery formats suitable for automated assembly. Tape & Reel and Cut Tape & Digi-Reel differ in reel configuration and handling but do not affect the component's electrical or mechanical performance when installed on PCBs.
