Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS75003QRHLREP is determined by strict equivalence across the following parameters:

• Base Product Number: Both parts must share the TPS75003 base designation, ensuring identical die and functional architecture
• Package / Case: Both parts must use the 20-VFQFN Exposed Pad package with identical physical dimensions (4.6x4.5mm)
• Electrical Specifications: Supply voltage range (2.2V ~ 6.5V) and quiescent current (75µA) must remain constant
• Mounting Type: Surface mount compatibility must be maintained
• Compliance Standards: RoHS3 compliance and MSL rating must be equivalent or superior

The TPS75003RHLT qualifies as a direct manufacturer-recommended substitute based on these criteria. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications within their respective operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

The TPS75003RHLT is the manufacturer-recommended substitute for the obsolete TPS75003QRHLREP. Both components maintain identical electrical specifications and physical packaging, ensuring direct functional compatibility in circuit designs.

The primary distinction between these parts is product status and operating temperature range. The TPS75003QRHLREP supports an extended temperature range of -55°C to 125°C, while the TPS75003RHLT operates within -40°C to 85°C. Design applications requiring operation below -40°C or above 85°C must account for this temperature specification difference.

Both parts carry ROHS3 compliance and MSL rating of 1 (Unlimited), confirming equivalent environmental and regulatory standing. The TPS75003RHLT benefits from Active product status, ensuring ongoing availability and supply chain support from Texas Instruments.

Frequently Asked Questions (FAQ)

Q: Can the TPS75003RHLT directly replace the TPS75003QRHLREP in existing designs?

A: Yes, the TPS75003RHLT is a direct functional substitute. Both parts share identical electrical specifications, package dimensions, and pinout. Designs operating within the -40°C to 85°C temperature range require no circuit modifications.

Q: What is the primary reason for substitution?

A: The TPS75003QRHLREP is classified as Obsolete. The TPS75003RHLT is the active equivalent, ensuring continued component availability and supply chain reliability.

Q: Are there temperature range limitations when substituting?

A: The TPS75003QRHLREP supports -55°C to 125°C operation, while the TPS75003RHLT operates from -40°C to 85°C. Applications requiring operation outside the -40°C to 85°C window must retain the original part number or identify alternative solutions.

Q: Do both parts require identical PCB layout and thermal management?

A: Yes. Both components use the 20-VQFN (4.6x4.5mm) package with exposed pad. PCB layout, thermal design, and assembly processes remain unchanged between the two parts.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), confirming equivalent environmental and regulatory compliance.

Q: What packaging options are available for the substitute part?

A: The TPS75003RHLT is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production procurement volumes.
