Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP130-28RL-7 is determined by strict equivalence across all electrical parameters and compliance certifications. The following criteria define valid substitutes:

Electrical Equivalence Requirements:

• Output voltage: 2.8V fixed
• Output current: 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: -40°C ~ 85°C (TA)

Compliance & Certification Requirements:

• RoHS3 Compliant
• MSL Rating: 1 (Unlimited)
• REACH Unaffected
• ECCN: EAR99

Package Compatibility: Substitutes may utilize different supplier device packages (SC-59R, SOT-23-3, SC-59-3) while maintaining the same mechanical footprint classification (TO-236-3, SC-59, SOT-23-3). Package selection depends on PCB layout and assembly process requirements.

All substitute parts are manufactured by Diodes Incorporated under the AP130 base product number, ensuring design continuity and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: AP130-28RG-7

The AP130-28RG-7 is the direct functional equivalent of the AP130-28RL-7, maintaining identical electrical specifications and supplier device package (SC-59R). This part carries Active product status, ensuring long-term availability and supply chain stability. Packaging is provided in Tape & Reel format, supporting automated assembly processes. Inventory availability (15100 units) provides immediate procurement capability.

Secondary Recommendation: AP130-28WG-7

The AP130-28WG-7 offers equivalent electrical performance with an alternative supplier device package (SC-59-3). This part is Active and available in Tape & Reel packaging. Selection of this variant requires PCB layout verification to confirm mechanical compatibility with the SC-59-3 package footprint. Inventory availability (9100 units) supports production requirements.

Package-Specific Alternative: AP130-28SAG-7

The AP130-28SAG-7 provides electrical equivalence with a SOT-23-3 supplier device package. This variant is suitable for designs requiring the smaller SOT-23-3 footprint. Active product status and Tape & Reel packaging support manufacturing continuity. Limited inventory (1070 units) may require lead time consideration for high-volume applications.

Obsolete Alternative: AP130-28WL-7

The AP130-28WL-7 maintains full electrical equivalence but carries Obsolete product status. This part should be considered only when existing inventory must be consumed or when design constraints mandate the SC-59-3 package variant. Long-term procurement of this part is not recommended.

All recommended substitutes maintain ROHS3 compliance, MSL Rating 1, and identical protection features (Over Current, Over Temperature, Short Circuit).

Frequently Asked Questions (FAQ)

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

A: Yes. The AP130-28RG-7 is electrically and mechanically equivalent to the AP130-28RL-7. Both utilize the SC-59R supplier device package and maintain identical electrical specifications. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. unspecified). No circuit modifications are required.

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

A: These are different supplier device package designations for the same TO-236-3 mechanical footprint classification. SC-59R and SC-59-3 are variations of the SC-59 package, while SOT-23-3 is a distinct package variant. PCB layout and assembly equipment compatibility must be verified before selecting a package variant. Consult the device datasheet for specific pin configuration and thermal characteristics.

Q: Why is AP130-28RL-7 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. Active equivalent alternatives (AP130-28RG-7, AP130-28WG-7, AP130-28SAG-7) are available to support design continuity and new production requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, MSL Rating 1 (Unlimited), and REACH Unaffected status, matching the compliance profile of the AP130-28RL-7.

Q: Which substitute part should I select for new designs?

A: AP130-28RG-7 is recommended for new designs. It provides direct electrical and package equivalence with Active product status and strong inventory availability. Selection of alternative packages (AP130-28WG-7 or AP130-28SAG-7) should be based on specific PCB layout requirements and assembly process constraints.

Q: What is the impact of different packaging formats (Tape & Reel vs. unspecified)?

A: Tape & Reel packaging is optimized for automated assembly processes and high-volume production. Unspecified packaging may indicate alternative formats (bulk, tube, or custom packaging). For production environments utilizing pick-and-place equipment, Tape & Reel format is standard. Verify packaging compatibility with your assembly process before procurement.

Q: Can I mix different AP130-28 variants in the same production run?

A: All listed variants maintain identical electrical specifications and protection features. Mixing variants is permissible from an electrical standpoint. However, verify mechanical compatibility with your PCB layout and assembly equipment to ensure consistent manufacturing quality and yield.
