Engineering Selection Recommendations

FMY1AT148 (Rohm Semiconductor): The FMY1AT148 provides direct electrical and mechanical compatibility with the DME201010R. This part maintains identical voltage rating (50V), package footprint (SC-74A/SOT-753), and power dissipation (300mW) while offering enhanced current capability (150mA versus 100mA) and transition frequency (180MHz versus 150MHz). The FMY1AT148 is ROHS3 Compliant with MSL Level 1 and carries Active product status with 61,800 units in stock. This substitute is suitable for direct replacement in applications requiring equivalent or improved performance specifications.

UMZ1NFHATR (Rohm Semiconductor): The UMZ1NFHATR meets the electrical requirements of the DME201010R with 50V voltage rating, 150mA collector current, and 180MHz transition frequency. This part is qualified to AEC-Q101 automotive standards and carries Automotive grade designation. However, the UMZ1NFHATR operates at reduced power dissipation (150mW versus 300mW) and utilizes a different package footprint (6-TSSOP/SC-88/SOT-363 versus SC-74A/SOT-753). The UMZ1NFHATR is ROHS3 Compliant with MSL Level 1 and carries Active product status with 22,069 units in stock. This substitute is applicable only when the reduced power rating and alternative package footprint are compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can the FMY1AT148 be used as a direct replacement for the DME201010R?

A: Yes. The FMY1AT148 maintains identical voltage rating (50V), package footprint (SC-74A/SOT-753), and power dissipation (300mW). The enhanced current capability (150mA) and transition frequency (180MHz) provide equivalent or improved performance for applications designed around the DME201010R specifications.

Q: What are the key differences between the FMY1AT148 and UMZ1NFHATR?

A: The FMY1AT148 maintains the original package footprint (SC-74A/SOT-753) and full power rating (300mW). The UMZ1NFHATR uses an alternative package (6-TSSOP/SC-88/SOT-363) and operates at reduced power dissipation (150mW). The UMZ1NFHATR includes automotive qualification (AEC-Q101).

Q: Is the UMZ1NFHATR suitable for all DME201010R applications?

A: The UMZ1NFHATR is suitable only when the application can accommodate the reduced power dissipation (150mW versus 300mW) and the alternative package footprint (6-TSSOP/SC-88/SOT-363). PCB layout modifications are required for package compatibility.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the FMY1AT148 and UMZ1NFHATR are ROHS3 Compliant with MSL Level 1 (Unlimited), meeting current environmental and reliability standards.

Q: What is the availability status of the substitute parts?

A: Both substitute parts carry Active product status. The FMY1AT148 has 61,800 units in stock, and the UMZ1NFHATR has 22,069 units in stock, ensuring supply chain continuity.

Q: Do the substitute parts maintain the same transistor configuration?

A: The FMY1AT148 maintains the identical NPN, PNP (Emitter Coupled) configuration. The UMZ1NFHATR uses a 1 NPN, 1 PNP configuration, which may differ in internal circuit topology and pin assignment.

Q: What operating temperature range is supported by the substitute parts?

A: Both substitute parts support the same maximum junction temperature (TJ) of 150°C as the original DME201010R.
