Key Parameters

Substitute Part Grouping Explanation

The AS7805ADTR-G1 qualifies as a direct substitute for the LSP7805AACA based on the following substitution criteria:

Functional Equivalence: Both components are linear voltage regulators manufactured by Diodes Incorporated, sharing the same base product number (LSP7805 / AS7805 family). Both deliver fixed positive 5V output regulation at 1A output current capacity.

Regulatory Compliance: The substitute part maintains ROHS3 compliance and REACH Unaffected status, matching the environmental and regulatory requirements of the original component.

Supply Availability: The AS7805ADTR-G1 is in Active product status with substantial inventory availability (52,900 pcs), providing reliable sourcing compared to the Obsolete status of the LSP7805AACA.

Key Electrical Parameters: Output voltage (5V fixed), output current (1A), input voltage maximum (25V), and dropout voltage (2V @ 1A typical) are consistent across both components, ensuring functional compatibility in existing circuit designs.

Engineering Selection Recommendations

The AS7805ADTR-G1 is the qualified substitute for the obsolete LSP7805AACA. Selection of this substitute part is supported by the following engineering factors:

Product Status Transition: The LSP7805AACA is classified as Obsolete, making continued sourcing from original inventory unsustainable for long-term production or support. The AS7805ADTR-G1 maintains Active product status, ensuring ongoing availability and manufacturer support.

Regulatory Compliance Continuity: Both components maintain identical RoHS3 compliance and REACH Unaffected status, ensuring no regulatory barriers to substitution in applications subject to environmental directives.

Functional Compatibility: The electrical specifications provided for the AS7805ADTR-G1 (5V fixed output, 1A output current, 25V maximum input, 2V typical dropout) are consistent with the linear voltage regulator function of the LSP7805AACA, supporting direct functional replacement in circuit designs.

Packaging Consideration: The AS7805ADTR-G1 is supplied in TO-252-3 (DPAK) surface mount packaging with Tape & Reel (TR) format. Design verification is required to confirm packaging compatibility with the original LSP7805AACA application, as the original part packaging specification was not provided in the available data.

Frequently Asked Questions (FAQ)

Q: Can the AS7805ADTR-G1 directly replace the LSP7805AACA in existing designs?

A: The AS7805ADTR-G1 provides functional equivalence as a linear voltage regulator with matching 5V fixed output and 1A output current specifications. Packaging compatibility must be verified, as the AS7805ADTR-G1 uses TO-252-3 surface mount packaging. If the original LSP7805AACA design uses a different package type, physical board modifications may be required.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: output voltage (5V fixed), output current capacity (1A), input voltage rating (25V maximum), and dropout voltage characteristics (2V @ 1A typical). The AS7805ADTR-G1 meets all these parameters.

Q: Is the AS7805ADTR-G1 compliant with the same environmental standards as the LSP7805AACA?

A: Yes. Both components are ROHS3 Compliant and REACH Unaffected, maintaining identical regulatory compliance status.

Q: What is the supply status difference between these parts?

A: The LSP7805AACA is Obsolete and no longer manufactured. The AS7805ADTR-G1 is Active with 52,900 pieces in current inventory, providing reliable long-term sourcing.

Q: Are there any protection features included in the substitute part?

A: The AS7805ADTR-G1 includes Over Temperature and Short Circuit protection features. These integrated protections enhance circuit reliability compared to designs relying solely on external protection mechanisms.

Q: What is the operating temperature range for the substitute part?

A: The AS7805ADTR-G1 operates across -40°C to 125°C, supporting applications requiring extended temperature performance.
