AP1086D50G-13 Equivalent & Substitute Parts

Part Overview

The AP1086D50G-13 is a linear voltage regulator IC from Diodes Incorporated, delivering a fixed 5V output at 1.5A in a TO-252-3 (DPAK) surface mount package. This device is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The regulator provides over-current and over-temperature protection suitable for general-purpose power management applications requiring positive fixed voltage regulation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP1086D50G-13 are selected based on the following critical parameters:

• Output Voltage: Fixed 5V output (non-negotiable)
• Package Type: TO-252-3 (DPAK) surface mount configuration
• Output Current Capability: Minimum 1.5A (equal or higher acceptable)
• Input Voltage Range: Maximum 12V or higher
• Protection Features: Over-current and over-temperature protection required
• Mounting Type: Surface mount only
• Compliance: ROHS3 compliant, REACH unaffected

Substitutes are grouped into two categories: parametric equivalents from the same manufacturer (AP1086 series variants) and manufacturer-recommended alternatives from other suppliers (AZ1084 and LD1086 series).

Parameter Comparison

Engineering Selection Recommendations

AP1086D50L-13 (Diodes Incorporated): This parametric equivalent maintains identical electrical specifications to the AP1086D50G-13 with the same 1.5A output current and 5V fixed output. However, this part is discontinued at DiGi Electronics with limited inventory (3,499 pcs). MSL rating of 3 requires controlled storage conditions. Suitable only for immediate replacement needs with existing stock availability.

AZ1084CD-5.0TRG1 (Diodes Incorporated): This manufacturer-recommended substitute offers higher output current capability (5A) while maintaining the same 5V output and TO-252-3 package. Input voltage rating remains at 12V maximum. PSRR performance improves to 72dB. Product status is active with strong inventory (10,200 pcs). MSL rating of 1 provides unlimited shelf life. Recommended for new designs requiring higher current headroom or when AP1086D50G-13 inventory is unavailable.

LD1086DT50TR (STMicroelectronics): This manufacturer-recommended substitute provides identical 1.5A output current and 5V fixed output in the same TO-252-3 package. Extended input voltage rating (30V maximum) and wider operating temperature range (-40°C to 125°C) offer greater design flexibility. PSRR performance is superior at 75dB. Product status is active with substantial inventory (15,650 pcs). MSL rating of 1 ensures unlimited shelf life. Recommended as the primary long-term substitute for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the AZ1084CD-5.0TRG1 replace the AP1086D50G-13 in existing designs?

A: Yes. Both devices deliver 5V fixed output in the TO-252-3 package with identical quiescent current and protection features. The AZ1084CD-5.0TRG1 provides higher output current (5A vs. 1.5A), making it a direct functional replacement. Pin-to-pin compatibility is maintained in the TO-252-3 package.

Q: What is the advantage of the LD1086DT50TR over the AP1086D50G-13?

A: The LD1086DT50TR maintains the same 1.5A output current and 5V output but extends the maximum input voltage to 30V (vs. 12V) and operating temperature range to -40°C to 125°C (vs. 0°C to 125°C). PSRR performance improves to 75dB. These enhancements provide greater design margin and environmental tolerance without changing the core electrical output specifications.

Q: Are all substitute parts in the same package?

A: Yes. All listed substitutes use the TO-252-3 (DPAK) surface mount package with identical pinout and footprint compatibility. No PCB layout modifications are required.

Q: Which substitute has the best long-term availability?

A: The LD1086DT50TR from STMicroelectronics is recommended for long-term production. It carries active product status with the highest inventory level (15,650 pcs) and MSL rating of 1 (unlimited shelf life). The AZ1084CD-5.0TRG1 is also active with strong inventory (10,200 pcs).

Q: Do all substitutes meet RoHS and REACH compliance?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the AP1086D50G-13.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) indicates storage and handling requirements. MSL 1 (unlimited) requires no special moisture control. MSL 3 (168 hours) requires controlled storage below 30°C and 60% relative humidity. The AP1086D50L-13 has MSL 3, requiring careful inventory management. The AZ1084CD-5.0TRG1 and LD1086DT50TR both have MSL 1, simplifying procurement and storage.
