Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DME501010R are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Electrical Parameters (Required Match or Exceed):

• Voltage - Collector Emitter Breakdown: 50V minimum
• Power dissipation: 150mW minimum
• Operating temperature range: 150°C (TJ) minimum
• Mounting type: Surface Mount
• Transistor configuration: NPN/PNP emitter-coupled array

Mechanical Parameters:

• Surface mount package compatibility
• Lead configuration suitable for PCB assembly

Compliance Requirements:

• RoHS compliance status
• Moisture Sensitivity Level 1 (Unlimited)

The identified substitutes (UMY1NTR and UMZ1NFHATR) meet or exceed all specified electrical parameters. Both parts feature higher maximum collector current ratings (150mA versus 100mA) and equal or superior transition frequency specifications, providing enhanced performance margins. Both maintain identical voltage ratings, power dissipation, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

UMY1NTR (Rohm Semiconductor) is suitable for direct substitution in applications where the original DME501010R package footprint (SMini5-F3-B, 6-SMD) can be adapted to the UMT5 package (5-TSSOP, SC-70-5, SOT-353). This part is currently in active production status with 47,400 units in stock. The UMY1NTR provides enhanced electrical performance with 150mA maximum collector current and transition frequencies of 180MHz and 140MHz, exceeding the original specification of 150MHz. ROHS3 compliance and unlimited moisture sensitivity rating align with the original part's environmental specifications.

UMZ1NFHATR (Rohm Semiconductor) is suitable for applications requiring automotive-grade qualification and AEC-Q101 certification. This part features a 6-TSSOP package (SC-88, SOT-363) that more closely matches the original 6-lead configuration. The UMZ1NFHATR is currently in active production with 22,069 units in stock. Electrical specifications match UMY1NTR with 150mA maximum collector current and dual transition frequency ratings. ROHS3 compliance and unlimited moisture sensitivity rating are maintained.

Both substitute parts exceed the original electrical specifications while maintaining voltage, power dissipation, and temperature ratings. Package selection between UMY1NTR and UMZ1NFHATR depends on PCB layout requirements and lead count compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can UMY1NTR and UMZ1NFHATR be used interchangeably with DME501010R?

A: Both parts meet the electrical parameter requirements for substitution. However, they differ in package configuration. UMY1NTR uses a 5-lead UMT5 package, while UMZ1NFHATR uses a 6-lead UMT6 package. The original DME501010R uses a 6-lead SMini5-F3-B package. PCB layout and footprint compatibility must be verified before selection.

Q: What are the key electrical advantages of the substitute parts?

A: Both UMY1NTR and UMZ1NFHATR provide higher maximum collector current (150mA versus 100mA) and equal or superior transition frequency performance (180MHz/140MHz versus 150MHz). Voltage ratings, power dissipation, and operating temperature specifications remain identical to the original part.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both UMY1NTR and UMZ1NFHATR are ROHS3 compliant, meeting current environmental regulations. The original DME501010R was RoHS compliant, and both substitutes maintain or exceed this compliance level.

Q: What is the difference between UMY1NTR and UMZ1NFHATR?

A: The primary differences are package configuration and automotive qualification. UMY1NTR uses a 5-lead UMT5 package, while UMZ1NFHATR uses a 6-lead UMT6 package with AEC-Q101 automotive qualification. Electrical specifications are equivalent between the two parts.

Q: Are moisture sensitivity levels equivalent across all three parts?

A: Yes. The DME501010R, UMY1NTR, and UMZ1NFHATR all feature Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the current availability status of these parts?

A: The original DME501010R is discontinued at DiGi Electronics. UMY1NTR has 47,400 units in stock and is in active production. UMZ1NFHATR has 22,069 units in stock and is in active production. Both substitutes are readily available for procurement.
