AP130-28RG-7 Equivalent & Substitute Parts

Part Overview

The AP130-28RG-7 is a linear voltage regulator IC manufactured by Diodes Incorporated, classified as a Power Management (PMIC) component. This device provides a fixed positive output of 2.8V at 300mA with integrated protection features including over-current, over-temperature, and short-circuit protection. The part is supplied in SC-59R (Tape & Reel) packaging and is currently in active product status with 15,100 units in stock.

Substitute parts are necessary when the SC-59R tape and reel packaging is unavailable, when alternative package configurations are required for specific PCB layouts, or when inventory constraints necessitate alternative sourcing from the same manufacturer's product line. All substitute parts maintain identical electrical performance specifications while offering different packaging or supplier device package options.

Substitute Part Grouping Explanation

Substitution logic for the AP130-28RG-7 is based on strict electrical and mechanical parameter equivalence within the AP130 product family. All substitute parts share identical electrical specifications: 2.8V fixed output, 300mA output current, 5.5V maximum input voltage, 0.5V maximum dropout voltage, 100 µA quiescent current, and identical protection features.

The primary differentiation among substitute parts is the supplier device package configuration:

SC-59R (Tape & Reel): AP130-28RG-7 - Primary part number with tape and reel packaging for automated assembly processes.

SOT-23-3 (Tape & Reel): AP130-28SAG-7 - Equivalent electrical performance with alternative surface mount package configuration.

SC-59-3 (Bulk): AP130-28WL-7 - Equivalent electrical performance with alternative supplier device package; product status is obsolete.

All parts are manufactured by Diodes Incorporated, operate across the identical temperature range (-40°C to 85°C), maintain ROHS3 compliance, and feature unlimited moisture sensitivity level (MSL 1). Substitution is valid when the mechanical package footprint and assembly method are compatible with the target application.

Engineering Selection Recommendations

AP130-28RG-7 (Primary Selection): This part is the recommended choice for new designs and production applications. It maintains active product status, offers the highest current inventory (15,100 units), and is supplied in SC-59R tape and reel packaging suitable for high-volume automated assembly processes. ROHS3 compliance and unlimited moisture sensitivity level ensure compatibility with modern manufacturing and environmental standards.

AP130-28SAG-7 (Active Alternative): This substitute is suitable when SOT-23-3 package configuration is required for PCB layout constraints or when SC-59R packaging is unavailable. The part maintains active product status with 1,070 units in inventory. Electrical performance is identical to the primary part. This option is appropriate for designs where the smaller SOT-23-3 footprint provides layout advantages.

AP130-28WL-7 (Obsolete - Not Recommended for New Designs): This part has reached obsolete product status and is not recommended for new design implementations. Although 9,200 units remain in inventory, the obsolete classification indicates discontinued manufacturer support and potential future unavailability. This part may only be considered for legacy system maintenance or repair applications where the SC-59-3 package is specifically required and no alternative exists.

All three parts maintain identical electrical specifications and ROHS3 compliance. Selection should be based on package compatibility with the target PCB design and current product status requirements.

Frequently Asked Questions (FAQ)

Q: Can AP130-28SAG-7 be used as a direct replacement for AP130-28RG-7?

A: AP130-28SAG-7 is electrically equivalent to AP130-28RG-7 with identical output voltage (2.8V), output current (300mA), dropout voltage (0.5V @ 300mA), and protection features. The primary difference is the supplier device package: SOT-23-3 versus SC-59R. Direct substitution is valid only if the PCB footprint and assembly process accommodate the SOT-23-3 package configuration.

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

A: SC-59R is the tape and reel packaging format of the SC-59 (also designated TO-236-3) package, optimized for automated pick-and-place assembly. SOT-23-3 is an alternative surface mount package with a different physical footprint and pin layout. Both are three-pin configurations suitable for surface mount assembly, but they are not mechanically interchangeable without PCB redesign.

Q: Why is AP130-28WL-7 marked as obsolete?

A: AP130-28WL-7 has reached end-of-life status with the manufacturer. Obsolete designation indicates that Diodes Incorporated no longer actively produces or supports this part variant. Although inventory remains available, future availability cannot be guaranteed, and manufacturer technical support may be limited.

Q: Are all three parts ROHS3 compliant?

A: Yes. AP130-28RG-7, AP130-28SAG-7, and AP130-28WL-7 are all ROHS3 compliant and feature unlimited moisture sensitivity level (MSL 1), meeting current environmental and manufacturing standards.

Q: What are the key electrical parameters that remain constant across all substitute parts?

A: All substitute parts maintain identical electrical specifications: 2.8V fixed output voltage, 300mA output current, 5.5V maximum input voltage, 0.5V maximum dropout voltage at 300mA, 100 µA quiescent current, 58dB PSRR at 100Hz, and integrated over-current, over-temperature, and short-circuit protection. Operating temperature range is -40°C to 85°C across all variants.

Q: Can I use AP130-28WL-7 in a new production design?

A: AP130-28WL-7 is not recommended for new design implementations due to its obsolete product status. New designs should utilize AP130-28RG-7 (primary recommendation) or AP130-28SAG-7 (if SOT-23-3 package is required). Obsolete parts present supply chain risk and may lack manufacturer support.

Q: What inventory levels are available for each part?

A: AP130-28RG-7 has 15,100 units in stock, AP130-28SAG-7 has 1,070 units in stock, and AP130-28WL-7 has 9,200 units in stock. Inventory levels should be verified at time of procurement.
