Substitute Part Grouping Explanation

Substitution eligibility for the AP7341D-36FS4-7 is determined by strict equivalence across the following critical parameters:

• Output voltage configuration: Fixed 3.6V positive output
• Output current capability: 300mA minimum
• Input voltage maximum rating: 5.25V
• Package type: 4-XDFN Exposed Pad (X2-DFN1010-4)
• Surface mount compatibility
• Operating temperature range: -40°C to 85°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The AP7343D-36FS4-7B meets all substitution criteria. Both parts share identical output voltage, current rating, input voltage specification, package geometry, and thermal operating range. Variations in dropout voltage and quiescent current remain within acceptable tolerance for this device class and do not preclude functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7341D-36FS4-7 and AP7343D-36FS4-7B are active production devices with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. The AP7343D-36FS4-7B is currently available in higher inventory (1084 pcs) compared to the primary part (973 pcs), providing supply chain flexibility. Selection between these parts depends on application-specific requirements regarding dropout voltage performance at rated current and quiescent current consumption. Both devices maintain identical electrical output specifications and package compatibility, ensuring direct substitution capability in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the AP7343D-36FS4-7B replace the AP7341D-36FS4-7 in existing designs?

A: Yes. Both parts deliver identical 3.6V fixed output at 300mA, operate across -40°C to 85°C, and use the same 4-XDFN Exposed Pad package. Electrical performance differences (dropout voltage and quiescent current) do not affect functional equivalence for standard linear regulator applications.

Q: What are the key differences between these two parts?

A: The AP7343D-36FS4-7B exhibits slightly higher dropout voltage (0.29V @ 300mA versus 0.27V @ 150mA) and marginally higher quiescent current (60 µA versus 50 µA). These variations remain within acceptable operating margins for this device category.

Q: Are both parts compatible with the same PCB layout?

A: Yes. Both parts use the X2-DFN1010-4 package with identical pin configuration and exposed pad geometry, enabling direct PCB substitution without layout modifications.

Q: Do both parts meet current compliance standards?

A: Yes. Both the AP7341D-36FS4-7 and AP7343D-36FS4-7B are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for commercial and industrial applications.

Q: Which part should be selected for new designs?

A: Selection is based on application requirements and supply availability. The AP7343D-36FS4-7B offers higher current inventory. Both parts are active production devices suitable for new designs requiring 3.6V fixed output linear regulation at 300mA.
