Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP1086DG-13 are identified based on strict electrical and mechanical compatibility criteria. The following parameters define valid substitution:

Critical Matching Parameters:

• Output Configuration: Positive
• Output Type: Adjustable
• Package / Case: TO-252-3 (identical physical footprint and pin configuration)
• Voltage - Input (Max): 12V (minimum requirement)
• Voltage - Output (Min/Fixed): 1.25V (minimum output voltage capability)
• Voltage - Output (Max): ≥5V (must support original output range)
• Current - Output: ≥1.5A (must meet or exceed original current rating)
• Voltage Dropout (Max): ≤1.4V @ rated current (thermal and efficiency considerations)
• Protection Features: Over Current, Over Temperature (safety requirements)
• Operating Temperature: 0°C ~ 125°C (thermal operating range)
• Mounting Type: Surface Mount (assembly compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

Two substitute parts meet these criteria with varying performance characteristics and product status classifications.

Parameter Comparison

Engineering Selection Recommendations

AP1086DL-13 (Parametric Equivalent): This part provides direct parametric equivalence to the AP1086DG-13 with identical electrical specifications and identical MSL rating. The primary distinction is product status: AP1086DL-13 is active and currently in production. This part is suitable for direct replacement in applications requiring 1.5A output current with 5V maximum output voltage. Both parts maintain ROHS3 compliance and identical thermal operating ranges.

AZ1084CD-ADJTRG1 (MFR Recommended): This part is designated as the manufacturer-recommended substitute. It provides enhanced performance characteristics including higher output current capability (5A versus 1.5A), extended maximum output voltage (10.5V versus 5V), and improved PSRR (72dB versus 60dB). The AZ1084CD-ADJTRG1 is active and maintains identical package, mounting type, and regulatory compliance. The higher MSL rating (3 versus 1) reflects different moisture sensitivity specifications. This part is suitable for applications requiring higher current capacity or extended output voltage range while maintaining the same physical footprint and pin configuration.

Both substitute parts maintain ROHS3 compliance, identical input voltage specifications, and identical protection features. Selection between them depends on application current requirements and output voltage range specifications.

Frequently Asked Questions (FAQ)

Q: Can AP1086DL-13 be used as a direct replacement for AP1086DG-13?

A: Yes. The AP1086DL-13 provides identical electrical specifications including output current (1.5A), output voltage range (1.25V to 5V), dropout voltage (1.4V @ 1.5A), and quiescent current (10 mA). Both parts use the TO-252-3 package with identical pin configuration. The primary difference is product status: AP1086DL-13 is active while AP1086DG-13 is obsolete.

Q: What are the key differences between AP1086DL-13 and AZ1084CD-ADJTRG1?

A: Both parts share identical package, mounting type, and regulatory compliance. The AZ1084CD-ADJTRG1 provides higher output current (5A versus 1.5A), extended maximum output voltage (10.5V versus 5V), and improved PSRR (72dB versus 60dB). The AZ1084CD-ADJTRG1 has MSL rating of 3 (168 Hours) compared to MSL 1 (Unlimited) for AP1086DL-13.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the TO-252-3 package (DPAK with 2 Leads + Tab, SC-63) with identical pin configuration, enabling direct PCB footprint compatibility.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For applications requiring 1.5A output current and 5V maximum output voltage, AP1086DL-13 provides direct equivalence. For applications requiring higher current capacity (up to 5A) or extended output voltage range (up to 10.5V), AZ1084CD-ADJTRG1 is suitable. Both parts are active and ROHS3 compliant.

Q: Do all parts maintain the same thermal operating range?

A: Yes. All three parts operate across 0°C to 125°C junction temperature range with identical over-current and over-temperature protection features.

Q: What is the significance of the MSL rating difference?

A: MSL (Moisture Sensitivity Level) indicates moisture sensitivity during storage and handling. AP1086DL-13 has MSL 1 (Unlimited storage without baking), while AZ1084CD-ADJTRG1 has MSL 3 (requires baking after 168 hours of exposure). This affects component handling and storage procedures but does not impact electrical performance or functionality.
