Key Parameters

Substitute Part Grouping Explanation

Substitution for the AP7343-10W5-7 is determined by the following critical parameters:

• Output Voltage: Fixed 1V output is the primary functional requirement
• Output Current: 300mA minimum capacity required
• Input Voltage Range: Maximum 5.25V input compatibility
• Voltage Dropout: 0.7V @ 300mA or better
• Package Compatibility: SOT-25 or equivalent surface mount package
• Control & Protection: Enable control and over-current protection features
• Operating Temperature Range: -40°C to 85°C minimum

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalent (Same Manufacturer): AP7343D-10W5-7 maintains identical electrical specifications and differs only in packaging format (Tape & Reel vs. bulk).

Category 2 - Cross-Manufacturer Equivalent: RP200N101D-TR-FE from Nisshinbo Micro Devices Inc. meets all critical electrical parameters with identical output voltage, current capacity, input voltage range, dropout voltage, and operating temperature. Package designation differs (SOT-23-5 vs. SOT-25) but both are SC-74A, SOT-753 form factors suitable for the same PCB footprint.

Parameter Comparison

Engineering Selection Recommendations

AP7343D-10W5-7 is the primary substitute for the discontinued AP7343-10W5-7. Both parts are manufactured by Diodes Incorporated with identical electrical specifications. The AP7343D-10W5-7 is currently active in production with significantly higher inventory availability (52,980 pcs vs. 875 pcs). Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating. Selection of AP7343D-10W5-7 requires no design modifications and provides direct functional replacement.

RP200N101D-TR-FE from Nisshinbo Micro Devices Inc. is a valid cross-manufacturer substitute meeting all critical electrical parameters: 1V fixed output, 300mA current capacity, 5.25V maximum input, and 0.7V dropout voltage. This part offers superior quiescent current performance (4 µA vs. 60 µA), reducing standby power consumption. PSRR is 70dB at 1kHz compared to 75dB for the Diodes parts, representing a 5dB difference in power supply rejection. Both parts carry RoHS compliance and unlimited MSL rating. The RP200N101D-TR-FE uses SOT-23-5 packaging while maintaining the same SC-74A, SOT-753 form factor, ensuring PCB footprint compatibility. This part is suitable for applications where lower quiescent current provides design advantage.

Frequently Asked Questions (FAQ)

Q: Can AP7343D-10W5-7 be used as a direct replacement for AP7343-10W5-7?

A: Yes. Both parts are manufactured by Diodes Incorporated with identical electrical specifications including 1V output, 300mA current capacity, 0.7V dropout voltage, and -40°C to 85°C operating range. The only difference is packaging format (Tape & Reel vs. bulk). No design modifications are required.

Q: What is the key difference between AP7343D-10W5-7 and RP200N101D-TR-FE?

A: Both parts meet the critical electrical requirements for 1V, 300mA linear regulation. The RP200N101D-TR-FE offers lower quiescent current (4 µA vs. 60 µA) and is manufactured by Nisshinbo Micro Devices Inc. instead of Diodes Incorporated. PSRR is 70dB vs. 75dB. Both use compatible SOT-23-5/SOT-25 packaging in the same form factor.

Q: Are package differences between SOT-25 and SOT-23-5 significant for substitution?

A: Both parts use SC-74A, SOT-753 form factors with identical PCB footprints. The supplier device package designation (SOT-25 vs. SOT-23-5) reflects internal pin configuration but does not affect physical mounting or electrical compatibility for this application.

Q: Which substitute part should be selected for new designs?

A: AP7343D-10W5-7 is recommended for direct replacement of the discontinued AP7343-10W5-7 due to identical specifications and same manufacturer. RP200N101D-TR-FE is suitable when lower quiescent current provides design benefit, with the trade-off of slightly lower PSRR performance.

Q: Are all substitute parts RoHS compliant?

A: Yes. AP7343D-10W5-7 is ROHS3 compliant. RP200N101D-TR-FE is RoHS compliant. Both parts carry unlimited moisture sensitivity rating (MSL 1) and EAR99 export classification.

Q: What inventory status should influence part selection?

A: AP7343D-10W5-7 has significantly higher inventory availability (52,980 pcs) compared to the original AP7343-10W5-7 (875 pcs). RP200N101D-TR-FE has 1,112 pcs available. For production continuity, AP7343D-10W5-7 is the preferred choice due to superior stock levels and active product status.
