AP130-33WG-7 Equivalent & Substitute Parts

Part Overview

The AP130-33WG-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 3.3V with a maximum dropout voltage of 0.5V at rated current. The device is actively produced and widely used in applications requiring stable 3.3V power supply rails with integrated protection against overcurrent, overtemperature, and short circuit conditions. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the allowed parameter range for this product category.

Substitute Part Grouping Explanation

Substitute parts for the AP130-33WG-7 are qualified based on strict electrical and mechanical parameter equivalence. All substitute candidates maintain identical output voltage (3.3V fixed), output current (300mA), input voltage maximum (5.5V), dropout voltage specification (0.5V @ 300mA), quiescent current (100 µA), PSRR (58dB at 100Hz), protection features (Over Current, Over Temperature, Short Circuit), operating temperature range (-40°C ~ 85°C), and RoHS3 compliance status.

The primary differentiator among qualified substitutes is the supplier device package designation, which reflects different tape and reel configurations or package variants within the allowed TO-236-3, SC-59, and SOT-23-3 family. All substitutes are manufactured by Diodes Incorporated and maintain Active product status.

Engineering Selection Recommendations

All three parts—AP130-33WG-7, AP130-33RG-7, and AP130-33SAG-7—are electrically equivalent and interchangeable from a functional standpoint. Selection among these parts should be based on:

Product Availability and Lead Time: Inventory levels vary across the three variants. AP130-33WG-7 has 9300 units in stock, AP130-33RG-7 has 1229 units, and AP130-33SAG-7 has 4200 units. Choose based on procurement requirements and supply chain constraints.

Moisture Sensitivity Considerations: AP130-33SAG-7 features MSL 1 (Unlimited), providing superior moisture tolerance compared to AP130-33WG-7 and AP130-33RG-7, both rated MSL 3 (168 Hours). For applications with extended storage or high-humidity environments, AP130-33SAG-7 is the preferred choice.

Package Configuration: The supplier device package designation (SC-59-3, SC-59R, or SOT-23-3) reflects tape and reel configuration differences. Verify compatibility with your pick-and-place equipment and PCB layout requirements before final selection.

Compliance Status: All three parts maintain ROHS3 compliance, REACH Unaffected status, and Active product status, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Are AP130-33WG-7, AP130-33RG-7, and AP130-33SAG-7 electrically interchangeable?

A: Yes. All three parts deliver identical electrical performance: 3.3V fixed output at 300mA, 0.5V maximum dropout voltage, 100 µA quiescent current, and 58dB PSRR at 100Hz. They share identical protection features and operating temperature range.

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

A: These designations indicate different tape and reel configurations within the TO-236-3 / SC-59 / SOT-23-3 package family. The physical component dimensions and pinout remain compatible, but the supplier packaging format differs. Verify compatibility with your assembly equipment specifications.

Q: Why does AP130-33SAG-7 have a lower Moisture Sensitivity Level (MSL 1) compared to the others (MSL 3)?

A: MSL 1 (Unlimited) indicates superior moisture resistance and longer shelf life without baking requirements. This makes AP130-33SAG-7 preferable for applications with extended storage periods or high-humidity storage conditions.

Q: Can I substitute AP130-33WG-7 with AP130-33RG-7 or AP130-33SAG-7 on an existing PCB design?

A: Yes, provided your PCB layout and pick-and-place equipment accommodate the specific supplier device package. Verify footprint compatibility and tape reel specifications with your assembly partner before implementation.

Q: Are all three parts RoHS3 compliant?

A: Yes. AP130-33WG-7, AP130-33RG-7, and AP130-33SAG-7 are all ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.
