Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7354D-28FS4-7 are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Fixed output voltage of 2.8V
• Output current rating of 150mA
• Maximum input voltage of 5.25V or higher
• Voltage dropout specification of 0.4V @ 150mA
• Surface mount package in 4-XDFN or equivalent form factor
• Enable control and over-current protection features
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and MSL 1 rating

All identified substitutes maintain these core electrical and mechanical specifications, ensuring direct compatibility in circuit applications designed for the AP7354D-28FS4-7.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full ROHS3 compliance with MSL 1 rating, confirming their suitability for production applications. The AP7354D-28FS4-7, AP7351D-28FS4-7B, and AP7354-28FS4-7 are all Diodes Incorporated products with identical electrical specifications and package form factors. The RP110L281D-TR from Nisshinbo Micro Devices Inc. provides an alternative from a different manufacturer while maintaining all critical electrical parameters and compliance certifications.

Selection between these parts should be based on availability, supply chain considerations, and any manufacturer-specific design requirements. The AP7354-28FS4-7 variant offers the highest inventory availability at 3599 pieces. The RP110L281D-TR provides the largest stock position at 10098 pieces, making it suitable for high-volume applications where supply continuity is critical.

Frequently Asked Questions (FAQ)

Q: Can AP7351D-28FS4-7B be used as a direct replacement for AP7354D-28FS4-7?

A: Yes. Both devices share identical output voltage (2.8V), output current (150mA), voltage dropout (0.4V @ 150mA), package type (4-XDFN Exposed Pad), and operating temperature range (-40°C to 85°C). The primary difference is quiescent current (1 µA vs. 0.6 µA) and PSRR specification (60dB at 1kHz vs. not specified). These differences do not affect functional compatibility in standard linear regulator applications.

Q: What is the key difference between the Diodes Incorporated and Nisshinbo Micro Devices variants?

A: The RP110L281D-TR from Nisshinbo Micro Devices Inc. maintains all critical electrical specifications but has a maximum input voltage of 5.25V compared to 5.5V for Diodes parts, and a higher quiescent current of 2 µA. The package form factor and all protection features remain identical. Selection depends on input voltage requirements and power consumption constraints.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed parts use the 4-XDFN Exposed Pad surface mount package with identical mechanical dimensions and pin configurations, ensuring direct PCB compatibility without layout modifications.

Q: Do all substitute parts have the same compliance certifications?

A: Yes. All parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, confirming equivalent environmental and regulatory compliance for production use.

Q: Which substitute part should be selected for lowest power consumption?

A: The AP7354D-28FS4-7 and AP7354-28FS4-7 both feature 0.6 µA quiescent current, which is lower than AP7351D-28FS4-7B (1 µA) and RP110L281D-TR (2 µA). For applications prioritizing minimal standby current draw, these variants are preferred.
