AP130-28WG-7 Equivalent & Substitute Parts

Part Overview

The AP130-28WG-7 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed 2.8V output at 300mA with integrated protection features including over-current, over-temperature, and short-circuit protection. The part is currently in active production status with 9,100 units available in stock.

Substitute parts become necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when alternative packaging options are required for specific manufacturing processes or design requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the AP130-28WG-7 is determined by strict parametric matching across the following criteria:

Critical Parameters for Substitution:

Output voltage: 2.8V (fixed)
Output current capability: 300mA
Input voltage maximum: 5.5V
Voltage dropout: 0.5V @ 300mA
Quiescent current: 100 µA
PSRR: 58dB (100Hz)
Protection features: Over Current, Over Temperature, Short Circuit
Operating temperature range: -40°C ~ 85°C

Engineering Selection Recommendations

Primary Selection (Active Status): AP130-28WG-7, AP130-28RG-7, and AP130-28SAG-7 are all active production parts with identical electrical specifications. Selection between these three parts is determined solely by packaging requirements:

AP130-28WG-7: SC-59-3 package designation
AP130-28RG-7: SC-59R package designation (highest inventory availability at 15,100 units)
AP130-28SAG-7: SOT-23-3 package designation (lowest inventory at 1,070 units)

All three active parts maintain ROHS3 compliance and are suitable for new designs.

Secondary Selection (Obsolete Status): AP130-28WL-7 carries obsolete product status and should be selected only when existing legacy designs or inventory constraints require its use. This part maintains identical electrical specifications and ROHS3 compliance but is no longer in active production.

Frequently Asked Questions (FAQ)

Q: Can AP130-28RG-7 replace AP130-28WG-7 in existing designs? A: Yes. Both parts are electrically identical with matching output voltage (2.8V), output current (300mA), dropout voltage (0.5V @ 300mA), and all protection features. The difference is the supplier device package designation (SC-59R versus SC-59-3). PCB layout compatibility depends on physical package footprint compatibility between SC-59R and SC-59-3 designations.

Q: What is the difference between SC-59-3 and SOT-23-3 packages? A: Both designations refer to surface-mount packages with three leads. The physical dimensions and lead spacing may differ. AP130-28SAG-7 uses SOT-23-3 designation while AP130-28WG-7 uses SC-59-3. Verify PCB footprint compatibility before substitution.

Q: Why is AP130-28WL-7 marked as obsolete? A: AP130-28WL-7 has reached end-of-life status. While electrically equivalent and currently in stock (9,200 units), it is no longer in active production. Use active alternatives (AP130-28WG-7, AP130-28RG-7, or AP130-28SAG-7) for new designs.

Q: Are all substitute parts ROHS3 compliant? A: Yes. AP130-28WG-7, AP130-28RG-7, AP130-28SAG-7, and AP130-28WL-7 are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Which substitute part has the best inventory availability? A: AP130-28RG-7 has the highest inventory at 15,100 units, followed by AP130-28WL-7 at 9,200 units and AP130-28WG-7 at 9,100 units. AP130-28SAG-7 has the lowest availability at 1,070 units.
