Key Parameters

Substitute Part Grouping Explanation

Substitution for the AP1084D50G-13 is determined by the following critical parameters:

• Fixed output voltage of 5V
• Output current capability of 5A
• Maximum input voltage of 12V
• TO-252-3 package compatibility
• Surface mount mounting type
• Over-current and over-temperature protection
• Operating temperature range of 0°C to 125°C
• RoHS3 compliance

The AZ1084CD-5.0TRG1 meets all these substitution criteria. Both parts are manufactured by Diodes Incorporated, share identical electrical specifications for output voltage and current, operate within the same temperature range, and use the same package footprint. The primary distinction is product status: AP1084D50G-13 is obsolete, while AZ1084CD-5.0TRG1 is active.

Parameter Comparison

Engineering Selection Recommendations

The AZ1084CD-5.0TRG1 is the direct substitute for the obsolete AP1084D50G-13. Both parts are manufactured by Diodes Incorporated and maintain identical electrical and mechanical specifications across all critical parameters. The AZ1084CD-5.0TRG1 offers the advantage of active product status, ensuring ongoing availability and support.

Both parts comply with RoHS3 and REACH requirements, with EAR99 export classification and identical HTSUS coding. The dropout voltage specification for AZ1084CD-5.0TRG1 is measured at 4.5A rather than 5A, with a marginal increase of 0.1V, which remains within acceptable tolerance for most 5V regulation applications. The AZ1084CD-5.0TRG1 additionally provides PSRR specification of 72dB at 120Hz, offering improved noise rejection characteristics.

Frequently Asked Questions (FAQ)

Q: Can AZ1084CD-5.0TRG1 directly replace AP1084D50G-13 without PCB modifications?

A: Yes. Both parts use the TO-252-3 package with identical pinout and footprint. No PCB layout changes are required for direct substitution.

Q: What is the significance of the dropout voltage difference between the two parts?

A: AP1084D50G-13 specifies 1.4V dropout at 5A, while AZ1084CD-5.0TRG1 specifies 1.5V at 4.5A. This 0.1V difference is negligible for standard 5V regulation circuits and does not affect compatibility in typical applications.

Q: Why is AP1084D50G-13 listed as obsolete?

A: Product obsolescence is determined by the manufacturer. AZ1084CD-5.0TRG1 is the active replacement part from Diodes Incorporated.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3, REACH, and export classifications. Moisture sensitivity level is 1 (Unlimited) for both.

Q: What does the PSRR specification of 72dB indicate for AZ1084CD-5.0TRG1?

A: PSRR (Power Supply Rejection Ratio) of 72dB at 120Hz indicates the regulator's ability to reject AC noise on the input supply. This specification is provided for AZ1084CD-5.0TRG1 but not specified for AP1084D50G-13, representing an additional documented performance characteristic.
