Substitute Part Grouping Explanation

Substitute parts for the AP7354D-30FS4-7 are identified based on strict parametric equivalence across the following critical criteria:

• Output Voltage: Fixed 3V output
• Output Current Capability: 150mA minimum
• Input Voltage Range: Maximum 5.5V
• Dropout Voltage: 0.35V @ 150mA or lower
• Package Type: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Operating Temperature Range: -40°C to 85°C
• Protection and Control Features: Over Current protection and Enable control
• Compliance: ROHS3 Compliant, MSL 1

Only parts matching all these parameters across electrical performance, thermal specifications, and physical packaging are classified as direct substitutes. The AP7354-30FS4-7 meets all substitution criteria and is listed as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The AP7354-30FS4-7 is a direct parametric equivalent to the AP7354D-30FS4-7. Both parts are manufactured by Diodes Incorporated, maintain identical electrical specifications, and are housed in the same 4-XDFN package. Both parts carry active product status and full ROHS3 compliance with MSL 1 rating, ensuring compatibility in production environments without moisture sensitivity constraints.

Selection between these parts should be based on availability and procurement lead times. The AP7354-30FS4-7 currently maintains higher inventory levels (9528 units) compared to the AP7354D-30FS4-7 (1330 units), making it a viable alternative for supply chain continuity. Both parts are suitable for direct substitution in applications requiring 3V, 150mA regulated output with low quiescent current and over-current protection.

Frequently Asked Questions (FAQ)

Q: Can the AP7354-30FS4-7 be used as a direct replacement for the AP7354D-30FS4-7?

A: Yes. Both parts are parametrically identical across all electrical specifications, output voltage, current rating, dropout voltage, package type, and operating temperature range. They are interchangeable in circuit design and PCB layout.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 4-XDFN Exposed Pad package (X2-DFN1010-4 Type B), ensuring identical PCB footprints and pinout compatibility.

Q: What are the key parameters that determine substitutability for this regulator?

A: Substitutability is determined by matching output voltage (3V), output current (150mA), input voltage rating (5.5V max), dropout voltage (0.35V @ 150mA), package type (4-XDFN), operating temperature range (-40°C to 85°C), and protection features (over-current). All these parameters must align for a part to be considered a direct substitute.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the AP7354D-30FS4-7 and AP7354-30FS4-7 are ROHS3 compliant with MSL 1 rating, REACH unaffected status, and EAR99 export classification.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and procurement lead times. The AP7354-30FS4-7 offers higher stock availability, while both parts maintain identical performance characteristics and long-term availability as active products.
