Substitute Part Grouping Explanation

Substitute parts for the AP1084D25G-13 are identified based on strict electrical and mechanical parameter matching within the AP1084 regulator family. The following criteria determine substitution eligibility:

Fixed output voltage of 2.5V
Maximum output current of 5A
Maximum input voltage of 12V
TO-252-3 package configuration
Operating temperature range of 0°C to 125°C
Over Current and Over Temperature protection
ROHS3 compliance and RoHS Unaffected REACH status

Two substitute parts meet these criteria with variations in product status and packaging configuration.

Engineering Selection Recommendations

AP1084D25L-13 is the primary substitute for the obsolete AP1084D25G-13. Both parts share identical electrical specifications, including dropout voltage performance at 5A output current and quiescent current characteristics. The AP1084D25L-13 maintains active product status with ROHS3 compliance and REACH Unaffected certification. This part is available in Cut Tape (CT) packaging format with 19,481 units in stock.

AZ1084CD-2.5TRG1 serves as an alternative substitute with active product status and Tape & Reel (TR) packaging. This part exhibits a marginally higher dropout voltage specification (1.5V @ 4.5A versus 1.4V @ 5A), which may impact thermal performance in applications operating at maximum current. The AZ1084CD-2.5TRG1 includes PSRR specification of 72dB at 120Hz, providing additional performance data not available for the original part. This variant is suitable for high-volume production environments requiring automated tape-and-reel handling.

Both substitutes maintain full compliance with RoHS and REACH regulatory requirements applicable to the original part.

Frequently Asked Questions (FAQ)

Q: Can AP1084D25L-13 be used as a direct replacement for AP1084D25G-13?

A: Yes. Both parts deliver identical electrical performance with 2.5V fixed output at 5A maximum current, 1.4V dropout voltage at 5A, and matching operating temperature range. The primary difference is product status: AP1084D25L-13 is active while AP1084D25G-13 is obsolete. Packaging format differs (Cut Tape versus bulk), but the TO-252-3 package configuration is identical.

Q: What is the difference between AZ1084CD-2.5TRG1 and AP1084D25L-13?

A: Both are active products with identical output voltage, current rating, and package type. The AZ1084CD-2.5TRG1 specifies dropout voltage of 1.5V at 4.5A output, compared to 1.4V at 5A for AP1084D25L-13. The AZ1084CD-2.5TRG1 is supplied in Tape & Reel format for automated assembly, while AP1084D25L-13 is supplied in Cut Tape format. The AZ1084CD-2.5TRG1 includes published PSRR specification (72dB @ 120Hz).

Q: Are there any thermal or performance considerations when substituting these parts?

A: Dropout voltage specifications should be evaluated for your specific application current profile. The AP1084D25L-13 maintains 1.4V dropout at full 5A output. The AZ1084CD-2.5TRG1 specifies 1.5V dropout at 4.5A, which may result in slightly higher junction temperature at maximum current. All three parts include Over Current and Over Temperature protection.

Q: Do packaging format differences affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are handling and delivery methods only. The TO-252-3 package configuration, thermal characteristics, and electrical performance remain identical across all three parts.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. AP1084D25L-13 and AZ1084CD-2.5TRG1 both maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory compliance of the original AP1084D25G-13.
