Engineering Selection Recommendations

The UMG3NTR is a direct functional equivalent to the UMG3N-TP and is suitable for substitution in new designs and production applications. The following factors support this selection:

Product Status: The UMG3NTR maintains active product status with Rohm Semiconductor, ensuring continued availability and supply chain stability. The UMG3N-TP is obsolete, making the UMG3NTR the appropriate choice for ongoing component procurement.

Compliance & Certifications: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings (MSL 1 - Unlimited), confirming environmental and regulatory compatibility.

Electrical Performance: All critical electrical parameters match or exceed the UMG3N-TP specifications. The UMG3NTR exhibits improved saturation voltage performance (150mV versus 300mV), which represents a performance advantage in switching applications.

Package Compatibility: Both components utilize identical 5-TSSOP / SC-70-5 / SOT-353 surface mount packaging, enabling direct PCB layout compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the UMG3NTR replace the UMG3N-TP in existing designs?

A: Yes. The UMG3NTR meets all electrical and physical specifications of the UMG3N-TP. Identical package geometry and pin configuration enable direct substitution without PCB redesign.

Q: What is the primary reason for substitution?

A: The UMG3N-TP is classified as obsolete. The UMG3NTR is an active product with equivalent specifications and superior saturation voltage characteristics, making it the appropriate replacement for new production and design continuity.

Q: Are there differences in the DC current gain specifications?

A: The UMG3N-TP specifies hFE minimum of 100 at 100mA and 5V. The UMG3NTR specifies hFE minimum of 100 at 1mA and 5V. Both parts meet the minimum gain requirement; the UMG3NTR specification is measured at a lower collector current, which is standard practice for pre-biased transistor characterization.

Q: Does the UMG3NTR have better saturation voltage performance?

A: Yes. The UMG3NTR exhibits a maximum saturation voltage of 150mV compared to 300mV for the UMG3N-TP, both measured at identical bias conditions (250µA base current, 5mA collector current). This represents improved switching efficiency.

Q: Are packaging and moisture sensitivity identical?

A: Yes. Both parts use 5-TSSOP / SC-70-5 / SOT-353 surface mount packaging and maintain MSL 1 (Unlimited) moisture sensitivity ratings, confirming identical handling and storage requirements.

Q: What is the availability difference between these parts?

A: The UMG3N-TP has 879 pieces in stock but is obsolete. The UMG3NTR has 185,100 pieces in stock and maintains active product status, ensuring long-term supply availability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the UMG3N-TP and UMG3NTR are ROHS3 compliant, confirming environmental and regulatory compatibility for applications requiring RoHS certification.
