Engineering Selection Recommendations

The UMY1NTR manufactured by Rohm Semiconductor is a direct functional equivalent to the obsolete UMY1N-TP. Selection of the UMY1NTR is supported by the following factors:

Product Status: The UMY1NTR maintains active product status with substantial inventory availability (47,400 pieces), ensuring reliable long-term supply compared to the obsolete UMY1N-TP.

Electrical Equivalence: All critical electrical parameters are identical or superior. The UMY1NTR maintains the same maximum collector current (150mA), breakdown voltage (50V), power dissipation (150mW), and DC current gain specifications. The transition frequency of the UMY1NTR (180MHz, 140MHz) meets or exceeds the UMY1N-TP specification (140MHz).

Mechanical Compatibility: Both devices utilize identical 5-TSSOP (SOT-353) surface mount packaging, enabling direct PCB footprint compatibility without layout modifications.

Compliance and Environmental: The UMY1NTR maintains ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) identical to the main part. REACH status is unaffected, confirming regulatory alignment.

Saturation Voltage: The UMY1NTR offers improved saturation voltage performance (400mV @ 5mA, 50mA) in addition to the specified 500mV rating, providing enhanced switching efficiency.

Frequently Asked Questions (FAQ)

Q: Can the UMY1NTR be used as a direct replacement for the UMY1N-TP in existing designs?

A: Yes. The UMY1NTR is electrically and mechanically equivalent to the UMY1N-TP. Both devices share identical package geometry (5-TSSOP, SOT-353), electrical ratings (50V, 150mA, 150mW), and environmental specifications. No circuit modifications or PCB redesign are required.

Q: What are the key differences between the UMY1N-TP and UMY1NTR?

A: The primary differences are manufacturer (Micro Commercial Co versus Rohm Semiconductor) and product status (Obsolete versus Active). The UMY1NTR offers superior transition frequency performance (180MHz versus 140MHz) and improved saturation voltage characteristics. All other electrical and mechanical parameters are identical.

Q: Are there any package compatibility concerns when substituting the UMY1NTR for the UMY1N-TP?

A: No. Both parts are housed in the 5-TSSOP (SC-70-5, SOT-353) surface mount package. Pin configuration, lead spacing, and PCB footprint requirements are identical, enabling direct substitution without layout modifications.

Q: Does the UMY1NTR meet the same compliance standards as the UMY1N-TP?

A: Yes. The UMY1NTR is ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the environmental and regulatory specifications of the UMY1N-TP. REACH status is unaffected.

Q: Why is the UMY1N-TP classified as obsolete?

A: The UMY1N-TP is no longer in active production. The UMY1NTR serves as the active equivalent part from Rohm Semiconductor, ensuring continued availability and supply chain reliability for this transistor array configuration.

Q: What is the inventory status of the UMY1NTR?

A: The UMY1NTR is available in substantial quantity (47,400 pieces new original in stock), providing reliable component availability for production and field replacement applications.

Q: Are there any thermal or frequency limitations when using the UMY1NTR instead of the UMY1N-TP?

A: No. The UMY1NTR maintains the same maximum operating temperature (150°C TJ) and meets the 140MHz transition frequency requirement. The UMY1NTR additionally supports 180MHz operation, providing performance margin beyond the original specification.
