Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7341D-285FS4-7 are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Output Voltage (Fixed): 2.85V
• Output Current Rating: 300mA
• Input Voltage (Max): 5.25V
• Package Type: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Control Features: Enable function
• Protection Features: Over-current protection
• Operating Temperature Range: -40°C to 85°C
• Compliance Standards: ROHS3, REACH Unaffected

The AP7343-285FS4-7B qualifies as a parametric equivalent because it maintains identical output voltage, current rating, input voltage maximum, package configuration, control and protection features, temperature range, and compliance certifications. Variations in dropout voltage and quiescent current specifications remain within acceptable tolerance for this product category and do not affect primary circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7341D-285FS4-7 and AP7343-285FS4-7B are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use. The AP7343-285FS4-7B offers higher inventory availability at 1041 units compared to 647 units for the AP7341D-285FS4-7, providing supply chain flexibility. Both devices maintain identical electrical performance in the primary functional parameters: fixed 2.85V output, 300mA current delivery, 5.25V maximum input, and identical package footprint. Selection between these parts should be based on inventory requirements, lead time considerations, and specific application tolerance for the minor variations in dropout voltage and quiescent current specifications.

Frequently Asked Questions (FAQ)

Q: Can the AP7343-285FS4-7B be used as a direct replacement for the AP7341D-285FS4-7 in existing designs?

A: Yes. Both parts share identical output voltage (2.85V), output current (300mA), input voltage maximum (5.25V), package configuration (4-XDFN Exposed Pad), control features (Enable), protection features (Over-current), and operating temperature range (-40°C to 85°C). The parts are pin-compatible and functionally equivalent for circuit applications.

Q: What are the differences between these two parts?

A: The AP7343-285FS4-7B has a maximum dropout voltage of 0.3V at 300mA compared to 0.27V at 150mA for the AP7341D-285FS4-7, and a quiescent current of 60 µA versus 50 µA. These differences are minor and do not affect primary regulator functionality in standard applications.

Q: Are both parts available in the same package?

A: Yes. Both the AP7341D-285FS4-7 and AP7343-285FS4-7B use the 4-XDFN Exposed Pad package (X2-DFN1010-4) with identical footprint and pinout for surface mount assembly.

Q: Do these parts meet current compliance requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component use in regulated markets.

Q: Which part should I select for new designs?

A: Selection should be based on inventory availability and supply chain requirements. The AP7343-285FS4-7B has higher stock levels (1041 units) compared to the AP7341D-285FS4-7 (647 units). Both parts are active production items suitable for new design implementation.
