AP130-28WL-7 Equivalent & Substitute Parts

Part Overview

The AP130-28WL-7 is a linear voltage regulator IC from Diodes Incorporated designed for positive fixed output applications. This Surface Mount device delivers 300mA output current at a fixed 2.8V output voltage with a maximum dropout voltage of 0.5V at rated current. The part is classified as Obsolete, making identification of active equivalent alternatives essential for ongoing production and design continuity.

Substitute Part Grouping Explanation

Substitution of the AP130-28WL-7 is determined by strict equivalence across the following critical parameters: output voltage (2.8V fixed), maximum output current (300mA), maximum input voltage (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), and mounting type (Surface Mount). All substitute parts maintain identical electrical specifications and regulatory compliance (ROHS3, REACH Unaffected, EAR99).

Substitute parts differ only in packaging designation and product status. The AP130-28WG-7 and AP130-28RG-7 are Active products supplied in Tape & Reel packaging. The AP130-28SAG-7 is an Active product with SOT-23-3 package designation. All three alternatives provide direct functional equivalence to the obsolete AP130-28WL-7.

Engineering Selection Recommendations

All three substitute parts—AP130-28WG-7, AP130-28RG-7, and AP130-28SAG-7—are Active products with full ROHS3 compliance and REACH Unaffected status, providing superior product lifecycle support compared to the Obsolete AP130-28WL-7. Selection among substitutes depends on packaging requirements and supply chain considerations.

The AP130-28WG-7 and AP130-28RG-7 maintain SC-59 package variants (SC-59-3 and SC-59R respectively) in Tape & Reel format, suitable for automated assembly processes. The AP130-28SAG-7 offers SOT-23-3 package designation, also in Tape & Reel format. All three parts carry identical electrical specifications, regulatory certifications (ROHS3 Compliant, REACH Unaffected, EAR99), and moisture sensitivity ratings (MSL 1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can AP130-28WG-7, AP130-28RG-7, or AP130-28SAG-7 directly replace AP130-28WL-7 in existing designs?

A: Yes. All three substitute parts maintain identical electrical performance across output voltage (2.8V), output current (300mA), input voltage rating (5.5V maximum), dropout voltage (0.5V @ 300mA), quiescent current (100 µA), PSRR (58dB @ 100Hz), protection features, and operating temperature range (-40°C ~ 85°C). Functional compatibility is complete.

Q: What is the difference between AP130-28WG-7, AP130-28RG-7, and AP130-28SAG-7?

A: The primary differences are packaging designation and supplier device package format. AP130-28WG-7 uses SC-59-3 package, AP130-28RG-7 uses SC-59R package, and AP130-28SAG-7 uses SOT-23-3 package. All are supplied in Tape & Reel format for production environments. Electrical specifications remain identical across all three variants.

Q: Why is AP130-28WL-7 classified as Obsolete?

A: The AP130-28WL-7 has reached end-of-life status. Active alternatives with identical electrical specifications are available to support ongoing production requirements.

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All parts maintain identical regulatory status: ROHS3 Compliant, REACH Unaffected, EAR99 classification, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should be selected for new designs?

A: Any of the three Active substitutes (AP130-28WG-7, AP130-28RG-7, AP130-28SAG-7) are suitable for new designs. Selection should be based on packaging compatibility with existing PCB layouts and assembly equipment capabilities.
