AP130-35SAG-7 Equivalent & Substitute Parts

Part Overview

The AP130-35SAG-7 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This positive fixed output regulator delivers 300mA at 4.6V with a maximum dropout voltage of 0.5V at rated current. The device is actively produced and widely used in applications requiring stable low-voltage power supply regulation with integrated protection features. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or specific packaging preferences.

Substitute Part Grouping Explanation

Substitute parts for the AP130-35SAG-7 are qualified based on strict electrical and mechanical parameter equivalence. All substitute candidates must meet the following criteria:

Identical output voltage: 4.6V fixed
Identical maximum output current: 300mA
Identical maximum input voltage: 5.5V
Identical maximum dropout voltage: 0.5V @ 300mA
Identical quiescent current: 100 µA
Identical PSRR: 58dB (100Hz)
Identical protection features: Over Current, Over Temperature, Short Circuit
Identical operating temperature range: -40°C ~ 85°C
Identical manufacturer: Diodes Incorporated
Identical base product number: AP130
Identical compliance status: ROHS3 Compliant, REACH Unaffected

Substitution is permitted across different supplier device packages (SOT-23-3, SC-59R, SC-59-3) as these represent alternative packaging formats for the same functional die, all classified as Surface Mount with identical mechanical compatibility within the TO-236-3 / SC-59 family.

Engineering Selection Recommendations

All three parts—AP130-35SAG-7, AP130-35RG-7, and AP130-35WG-7—are electrically and functionally equivalent linear voltage regulators from Diodes Incorporated. Selection between these parts is determined by packaging requirements and inventory availability rather than electrical performance differences.

AP130-35RG-7 offers the highest inventory availability at 9400 units and uses the SC-59R package format. AP130-35SAG-7 provides 6200 units in SOT-23-3 package format. AP130-35WG-7 is available in limited quantity (815 units) with SC-59-3 package format.

All three parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL Level 1 (Unlimited). All are actively produced by the manufacturer. Selection should be based on PCB layout requirements, available footprint space, and current supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can AP130-35RG-7 and AP130-35WG-7 be used interchangeably with AP130-35SAG-7?

A: Yes. All three parts deliver identical electrical performance: 4.6V fixed output at 300mA maximum current with 0.5V maximum dropout voltage. The differences are limited to supplier device package format (SOT-23-3 versus SC-59R versus SC-59-3), which represent alternative physical packaging of the same functional regulator die.

Q: What is the difference between SOT-23-3, SC-59R, and SC-59-3 packages?

A: These are three packaging variants within the TO-236-3 / SC-59 family. All are Surface Mount packages with identical electrical pin configurations and mechanical compatibility within the same package family. Package selection depends on PCB design requirements and manufacturing equipment capabilities.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). All are actively produced by Diodes Incorporated.

Q: Which part should I select based on availability?

A: AP130-35RG-7 has the highest current inventory (9400 units). AP130-35SAG-7 has 6200 units available. AP130-35WG-7 has limited availability (815 units). Selection should align with supply chain requirements and PCB packaging constraints.

Q: Do these parts require different PCB footprints?

A: PCB footprints differ based on the specific package variant (SOT-23-3, SC-59R, or SC-59-3). Verify footprint compatibility with your PCB design before component selection. All three packages are Surface Mount devices within the TO-236-3 / SC-59 family.
