Engineering Selection Recommendations

For applications currently using the AP130-18RL-7, the following selection criteria apply:

Diodes Incorporated Parametric Equivalents (AP130-18RG-7, AP130-18SAG-7, AP130-18WG-7, AP130-18WL-7): These parts maintain full electrical and functional equivalence to the AP130-18RL-7. Selection among these variants depends on packaging format requirements. AP130-18RG-7 and AP130-18SAG-7 are active products with current inventory availability. AP130-18WL-7 shares obsolete status with the original part. Package selection (SC-59 versus SOT-23-3) should align with PCB layout and assembly capabilities.

Richtek RT9198-18GV (Manufacturer-Recommended Substitute): This part satisfies all core electrical requirements with active product status and extended operating temperature range (-40°C to 125°C). The RT9198-18GV features improved voltage dropout performance (0.33V versus 0.5V) and includes an enable control feature not present in the AP130 series. This substitute is suitable for applications requiring enhanced thermal performance or control functionality.

All substitute parts maintain RoHS3 compliance and equivalent protection features. Selection should prioritize active product status parts (AP130-18RG-7, AP130-18SAG-7, AP130-18WG-7, RT9198-18GV) for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can AP130-18RG-7 directly replace AP130-18RL-7 in existing designs?

A: Yes. The AP130-18RG-7 is a parametric equivalent with identical electrical specifications. The primary difference is packaging format (Tape & Reel versus bulk). PCB layout and assembly processes remain unchanged.

Q: What is the difference between AP130-18SAG-7 and AP130-18RG-7?

A: Both parts deliver identical electrical performance. The distinction is the package type: AP130-18SAG-7 uses SOT-23-3, while AP130-18RG-7 uses SC-59R. Package selection depends on PCB footprint design and assembly equipment compatibility.

Q: Why is RT9198-18GV listed as a manufacturer-recommended substitute?

A: The RT9198-18GV meets all core electrical requirements (1.8V output, 300mA current, 5.5V maximum input) and maintains active product status. It offers improved voltage dropout (0.33V) and extended operating temperature range (-40°C to 125°C), making it suitable for applications with higher thermal demands.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the original AP130-18RL-7.

Q: Can I use RT9198-18GV in place of AP130-18RL-7 without circuit modifications?

A: The RT9198-18GV is electrically compatible for the core regulator function. However, it includes an enable control feature not present in the AP130-18RL-7. If this feature is not used in your circuit, it can be tied to the appropriate logic level. Consult the RT9198-18GV datasheet for enable pin configuration.

Q: What is the inventory status of these substitute parts?

A: AP130-18RG-7 (9,300 pcs), AP130-18SAG-7 (4,400 pcs), AP130-18WG-7 (9,400 pcs), and AP130-18WL-7 (10,547 pcs) are available from current stock. RT9198-18GV has 1,900 pcs in inventory.
