Substitute Part Grouping Explanation

Substitute parts for the AP1086K18G-13 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

  • Fixed output voltage of 1.8V
  • Output current rating of 1.5A
  • Maximum input voltage of 12V
  • TO-263 surface mount package configuration
  • Over-current and over-temperature protection
  • Operating temperature range of 0°C to 125°C
  • RoHS3 compliance and MSL Level 1 rating

Two substitute parts meet these criteria: the AZ1086CS2-1.8TRE1 (manufacturer-recommended active alternative) and the AP1086K18L-13 (parametric equivalent with identical electrical specifications).

Engineering Selection Recommendations

For new designs and production continuity, the AZ1086CS2-1.8TRE1 is the primary substitute. This part maintains active product status with Diodes Incorporated, ensuring long-term availability and supply chain stability. It shares identical package configuration, output specifications, and regulatory compliance (ROHS3, MSL Level 1) with the original AP1086K18G-13.

The AP1086K18L-13 provides a parametric equivalent alternative with complete electrical specification alignment, including quiescent current, PSRR, and protection features. However, this part also carries obsolete status, limiting its suitability for new production applications requiring extended component lifecycle.

Both substitutes are manufactured by Diodes Incorporated and maintain compatibility with existing PCB layouts designed for the TO-263 package. Selection between these options depends on supply availability and production timeline requirements.

Frequently Asked Questions (FAQ)

Q: Can the AZ1086CS2-1.8TRE1 be used as a direct replacement for the AP1086K18G-13?

A: Yes. Both parts deliver 1.8V at 1.5A in the TO-263 package with identical mechanical and electrical interface requirements. The AZ1086CS2-1.8TRE1 is the manufacturer-recommended active substitute.

Q: What is the difference between the AP1086K18L-13 and AP1086K18G-13?

A: These parts are parametric equivalents with identical electrical specifications (1.8V output, 1.5A current, 10 mA quiescent current, 60dB PSRR). Both are obsolete. The primary difference is packaging format: AP1086K18L-13 is supplied in cut tape.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the TO-263-3 D2PAK package with identical pinout and lead configuration, enabling direct PCB substitution without layout modifications.

Q: Does the AZ1086CS2-1.8TRE1 meet the same compliance requirements?

A: Yes. The AZ1086CS2-1.8TRE1 is ROHS3 compliant with MSL Level 1 rating, matching the original part's regulatory status.

Q: Why is the AP1086K18G-13 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The AZ1086CS2-1.8TRE1 represents the active product line continuation for this functional specification.
