AP130-28SAG-7 Equivalent & Substitute Parts

Part Overview

The AP130-28SAG-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 a maximum dropout voltage of 0.5V, housed in a SOT-23-3 surface mount package. The part is currently in Active product status with 1070 units available in stock. Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing flexibility, or when inventory constraints necessitate sourcing from alternative part variants within the same electrical specification family.

Substitute Part Grouping Explanation

Substitution eligibility for the AP130-28SAG-7 is determined by strict parametric equivalence across the following critical criteria:

Electrical Parameters (Must Match):

• Output voltage: 2.8V fixed
• Output current capability: 300mA
• Input voltage maximum: 5.5V
• Dropout voltage: 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

Mechanical & Compliance Parameters (Must Match):

• Manufacturer: Diodes Incorporated
• Base product number: AP130
• Mounting type: Surface Mount
• Package family: TO-236-3 / SC-59 / SOT-23-3 variants
• RoHS3 compliance
• MSL rating: 1

All identified substitute parts maintain identical electrical performance and regulatory compliance. Differences exist only in supplier device packaging designation, which reflects alternative package code formats from the same manufacturer for the same physical form factor.

Parameter Comparison

Engineering Selection Recommendations

AP130-28RG-7 (Primary Substitute): This part is electrically and mechanically equivalent to the AP130-28SAG-7 with Active product status and ROHS3 compliance. The SC-59R package designation represents an alternative supplier device package code for the same physical form factor. With 15100 units in stock, this part offers superior availability for high-volume procurement.

AP130-28WL-7 (Secondary Substitute): This part maintains full electrical equivalence and identical compliance certifications. However, its Obsolete product status indicates discontinued manufacturing. The SC-59-3 package designation is an alternative code variant. Selection of this part is appropriate only when existing inventory must be consumed or when legacy system requirements mandate this specific package code variant. Availability is limited to existing stock (9200 units).

All three parts are ROHS3 compliant, carry MSL rating 1, and are manufactured by Diodes Incorporated. Selection between active and obsolete variants depends on long-term supply chain requirements and manufacturing lifecycle planning.

Frequently Asked Questions (FAQ)

Q: Can AP130-28RG-7 be used as a direct replacement for AP130-28SAG-7? A: Yes. Both parts are parametrically equivalent with identical electrical specifications, output voltage, current rating, dropout voltage, and protection features. The difference in supplier device package designation (SOT-23-3 vs. SC-59R) reflects alternative package code formats for the same physical form factor and pin configuration.

Q: What is the difference between SOT-23-3, SC-59R, and SC-59-3 package codes? A: These are alternative supplier device package designations for the same physical package family (TO-236-3 / SC-59). All three variants represent identical mechanical dimensions, pin spacing, and mounting characteristics. The different codes reflect manufacturer documentation conventions and do not indicate functional or dimensional differences.

Q: Why is AP130-28WL-7 marked as Obsolete? A: Obsolete status indicates that Diodes Incorporated has discontinued active manufacturing of this part variant. While existing inventory remains available (9200 units), no new production is planned. This part should be selected only when legacy system requirements or existing stock consumption necessitate its use.

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

Q: Which substitute part should be selected for new designs? A: AP130-28RG-7 is recommended for new designs due to its Active product status and superior inventory availability (15100 units). This ensures long-term supply chain stability and manufacturing support from Diodes Incorporated.

Q: Can these parts be used interchangeably on the same PCB? A: Yes, provided the PCB layout accommodates the specific package code variant. All three parts share identical pin configurations and electrical characteristics. Verify PCB footprint compatibility with the selected supplier device package designation before assembly.
