AP7354-28FS4-7 Equivalent & Substitute Parts

Part Overview

The AP7354-28FS4-7 is a linear voltage regulator IC manufactured by Diodes Incorporated, designed for positive fixed output applications. This Surface Mount device delivers 150mA output current at a fixed 2.8V output voltage with a maximum dropout voltage of 0.4V at rated current. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic applications requiring regulated power distribution in compact form factors.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent performance specifications across different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7354-28FS4-7 are qualified based on the following critical parameters that determine functional equivalence:

• Fixed output voltage of 2.8V
• Output current capability of 150mA
• Maximum input voltage of 5.25V or higher
• Dropout voltage of 0.4V @ 150mA
• Surface Mount packaging in 4-XDFN Exposed Pad configuration
• Enable control feature and Over Current protection
• Operating temperature range of -40°C ~ 85°C
• ROHS3 compliance and MSL 1 rating

The AP7351D-28FS4-7B (Diodes Incorporated) and RP110L281D-TR (Nisshinbo Micro Devices Inc.) meet these core electrical and mechanical specifications, enabling direct substitution in applications where the AP7354-28FS4-7 is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AP7354-28FS4-7, AP7351D-28FS4-7B, and RP110L281D-TR—are actively produced and ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and use. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Manufacturer preference or qualification requirements within your supply chain
• Quiescent current specifications for ultra-low-power applications (AP7354-28FS4-7 at 0.6 µA offers the lowest standby current)
• Input voltage ceiling constraints (RP110L281D-TR maximum of 5.25V versus 5.5V for Diodes Incorporated parts)
• Established relationships with component distributors and manufacturers

All parts carry identical electrical performance for the primary application parameters: 2.8V fixed output, 150mA current delivery, and 0.4V dropout voltage at rated load.

Frequently Asked Questions (FAQ)

Q: Can AP7351D-28FS4-7B directly replace AP7354-28FS4-7 in existing designs?

A: Yes. Both parts share identical output voltage (2.8V), output current (150mA), dropout voltage (0.4V @ 150mA), package configuration (4-XDFN Exposed Pad), and operating temperature range (-40°C ~ 85°C). The primary difference is quiescent current (1 µA versus 0.6 µA), which is negligible in most applications.

Q: What are the package compatibility considerations?

A: All three substitute parts use the 4-XDFN Exposed Pad Surface Mount package. PCB layout, thermal management, and component placement remain identical across all three parts. No design modifications are required for package substitution.

Q: How does the RP110L281D-TR differ from the Diodes Incorporated parts?

A: The RP110L281D-TR (Nisshinbo Micro Devices Inc.) maintains electrical equivalence for output voltage, current, and dropout specifications. The maximum input voltage is 5.25V compared to 5.5V for Diodes parts, and quiescent current is 2 µA. These differences are application-dependent and should be evaluated against your specific circuit requirements.

Q: Are all parts suitable for high-temperature applications?

A: Yes. All three parts operate across the -40°C ~ 85°C temperature range, meeting standard industrial and commercial application requirements.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying inventory management and reducing component preparation time before assembly.
