Engineering Selection Recommendations

AZ1084CD-1.5TRG1 is the primary substitute for AP1084D15G-13. This part maintains identical electrical specifications and package configuration while offering active product status and current availability. The AZ1084CD-1.5TRG1 is supplied in Tape & Reel packaging, suitable for automated assembly processes.

AP1084D15L-13 serves as a secondary equivalent, matching all critical electrical parameters and package requirements. However, this part is discontinued at DiGi Electronics, limiting long-term procurement viability.

Both substitute parts are ROHS3 compliant and maintain the same operating temperature range and protection features as the original AP1084D15G-13.

Frequently Asked Questions (FAQ)

Q: Can AZ1084CD-1.5TRG1 directly replace AP1084D15G-13 in existing designs?

A: Yes. Both parts deliver 1.5V fixed output at 5A maximum current in identical TO-252-3 packages with matching electrical specifications and protection features. Pin configuration and functional behavior are equivalent.

Q: What is the difference between AP1084D15G-13 and AP1084D15L-13?

A: Both parts are parametrically equivalent with identical output voltage, current rating, package type, and operating temperature range. The primary difference is product status: AP1084D15G-13 is obsolete while AP1084D15L-13 is discontinued at DiGi Electronics. Neither affects functional performance in circuit applications.

Q: Why does AZ1084CD-1.5TRG1 show a different voltage dropout specification?

A: AZ1084CD-1.5TRG1 specifies 1.5V dropout at 4.5A, while AP1084D15G-13 specifies 1.4V at 5A. Both values fall within acceptable operating margins for 1.5V fixed output regulators. Circuit designs should account for the specified dropout voltage of the selected part during thermal and load analysis.

Q: Are all three parts RoHS compliant?

A: Yes. AP1084D15G-13, AZ1084CD-1.5TRG1, and AP1084D15L-13 are all ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).

Q: What packaging format is recommended for high-volume production?

A: AZ1084CD-1.5TRG1 is supplied in Tape & Reel format, optimized for automated pick-and-place assembly. AP1084D15G-13 and AP1084D15L-13 do not specify packaging format in available data.
