AP130-20YL-13 Equivalent & Substitute Parts

Part Overview

The AP130-20YL-13 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed 2V positive output at 300mA with integrated protection features including over-current, over-temperature, and short-circuit protection. The part is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Active alternatives with identical or superior electrical characteristics are available from the same manufacturer.

Substitute Part Grouping Explanation

Substitution of the AP130-20YL-13 is determined by strict equivalence across the following critical parameters:

Fixed output voltage of 2V
Output current capability of 300mA
Maximum input voltage of 5.5V
Voltage dropout specification
Package compatibility (SOT-89-3 or SOT-89R-3)
Identical protection feature set
Compliance certifications (ROHS3, REACH Unaffected)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in product status (obsolete vs. active) and packaging format (bulk vs. tape & reel) do not affect functional equivalence. The AP130-20YRL-13 exhibits a lower maximum dropout voltage (0.4V vs. 0.5V), representing an improved performance characteristic while maintaining full compatibility.

Engineering Selection Recommendations

For designs currently using the obsolete AP130-20YL-13, the AP130-20YG-13 provides direct functional replacement with active product status and identical electrical specifications. This part is available in tape & reel packaging with substantial inventory (15,100 pcs), ensuring supply chain continuity.

The AP130-20YRL-13 and AP130-20YRG-13 represent enhanced alternatives, both featuring active product status and improved voltage dropout performance (0.4V vs. 0.5V at 300mA). These variants utilize the SOT-89R-3 package variant while maintaining mechanical compatibility with the original TO-243AA footprint. The AP130-20YRL-13 offers the highest inventory availability (5,939 pcs) among active alternatives.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production transitions. Package selection between SOT-89-3 and SOT-89R-3 variants should be verified against PCB layout specifications, though both maintain identical electrical performance and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can AP130-20YG-13 be used as a direct replacement for AP130-20YL-13?

A: Yes. The AP130-20YG-13 maintains identical electrical specifications including 2V fixed output, 300mA current capability, 5.5V maximum input voltage, and 0.5V maximum dropout voltage. The primary difference is product status (active vs. obsolete) and packaging format (tape & reel vs. bulk). Functional compatibility is complete.

Q: What is the difference between SOT-89-3 and SOT-89R-3 packages?

A: Both packages are mechanically compatible with the TO-243AA footprint. The SOT-89R-3 designation indicates a tape & reel packaging format variant. Electrical performance and pin configuration remain identical. PCB layout compatibility should be verified with your design documentation.

Q: Why does AP130-20YRL-13 show lower dropout voltage?

A: The AP130-20YRL-13 specifies 0.4V maximum dropout at 300mA compared to 0.5V for other variants. This represents improved performance characteristics while maintaining full electrical and mechanical compatibility. This part is suitable for applications requiring lower dropout specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (AP130-20YG-13, AP130-20YRG-13, AP130-20YRL-13) maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for component selection.

Q: Which substitute part has the best inventory availability?

A: The AP130-20YRL-13 offers the highest inventory among active alternatives with 5,939 pcs in stock, followed by AP130-20YG-13 with 15,100 pcs. Both ensure supply continuity for production requirements.
