Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP7354-12FS4-7 is determined by strict equivalence across the following critical parameters:

• Output voltage specification (1.2V fixed)
• Output current rating (150mA)
• Maximum input voltage (5.5V)
• Voltage dropout characteristic (0.9V @ 150mA)
• Package type (4-XDFN Exposed Pad)
• Mounting configuration (Surface Mount)
• Operating temperature range (-40°C ~ 85°C)
• Control and protection features (Enable, Over Current)
• Compliance certifications (RoHS3, REACH Unaffected)
• Product status (Active)

The identified substitute parts maintain these core electrical and mechanical specifications, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AP7354-12FS4-7, AP7354D-12FS4-7, and AP7351D-12FS4-7B—maintain Active product status with full RoHS3 compliance and REACH Unaffected certification. Selection between these parts is based on the following considerations:

AP7354-12FS4-7 and AP7354D-12FS4-7 are functionally equivalent with identical quiescent current specifications (0.6 µA). The primary distinction is packaging designation (Type B for the D variant).

AP7351D-12FS4-7B differs in quiescent current (1 µA versus 0.6 µA) and includes specified PSRR performance (60dB at 1kHz), whereas the AP7354 variants do not specify PSRR. This makes AP7351D-12FS4-7B suitable for applications where power supply rejection ratio is a design requirement.

All parts are certified for unlimited moisture sensitivity (MSL 1) and operate across the identical temperature range. Selection should be based on specific application requirements regarding quiescent current performance and PSRR specifications.

Frequently Asked Questions (FAQ)

Q: Can AP7354D-12FS4-7 directly replace AP7354-12FS4-7?

A: Yes. Both parts share identical electrical specifications including output voltage (1.2V), output current (150mA), voltage dropout (0.9V @ 150mA), quiescent current (0.6 µA), and package configuration (4-XDFN Exposed Pad). The D designation indicates a packaging variant (Type B) but maintains full functional equivalence.

Q: What is the key difference between AP7351D-12FS4-7B and the AP7354 variants?

A: AP7351D-12FS4-7B has a higher quiescent current specification (1 µA compared to 0.6 µA) and includes documented PSRR performance (60dB at 1kHz). The AP7354 variants do not specify PSRR. Applications requiring low quiescent current should use AP7354 variants; applications requiring specified power supply rejection should use AP7351D-12FS4-7B.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 4-XDFN Exposed Pad package with Surface Mount configuration, ensuring identical PCB footprint compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are RoHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All operate across -40°C to 85°C temperature range.

Q: Which part should be selected for new designs?

A: All three parts carry Active product status. Selection depends on application-specific requirements: use AP7354 variants for standard applications with low quiescent current requirements; use AP7351D-12FS4-7B when PSRR specification is a design criterion.
