USBQ50415CE3/TR7 Equivalent & Substitute Parts

Part Overview

The USBQ50415CE3/TR7 is a Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for Ethernet applications requiring transient overvoltage protection. This bidirectional Zener-type TVS diode operates with a 15V reverse standoff voltage and provides 32V clamping at peak pulse current, delivering 500W peak pulse power dissipation in a surface-mount 4-VDFN package. The component is classified as Active product status and maintains full compliance with RoHS3 and REACH regulations. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain considerations necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

USBQNM50415CE3/TR7 is a direct functional and regulatory equivalent to USBQ50415CE3/TR7. Both components are manufactured by Microchip Technology and maintain identical electrical performance specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation.

Both parts are classified as Active product status, ensuring continued manufacturer support and availability. Both maintain full ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial Ethernet protection applications. The MSL rating of 1 (Unlimited) for both parts indicates no moisture sensitivity constraints during storage or handling.

Component selection should prioritize inventory availability and lead time requirements. The USBQNM50415CE3/TR7 variant currently maintains higher inventory levels (2133 pcs) compared to the USBQ50415CE3/TR7 (901 pcs), which may influence procurement decisions for high-volume or time-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can USBQNM50415CE3/TR7 be used as a direct replacement for USBQ50415CE3/TR7 in Ethernet protection circuits?

A: Yes. Both parts are electrically and mechanically identical, with matching 15V reverse standoff voltage, 32V clamping voltage, 5A peak pulse current, and 4-VDFN surface-mount packaging. No circuit modifications or re-qualification are required.

Q: Are there any differences in compliance or regulatory status between these two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited). Both maintain Active product status with Microchip Technology.

Q: What determines whether a part can substitute for USBQ50415CE3/TR7?

A: Substitution requires exact equivalence across all electrical parameters (voltage ratings, current ratings, power dissipation, capacitance), mechanical specifications (package type, mounting method, channel configuration), and regulatory certifications (RoHS, REACH, MSL). Any deviation disqualifies a part from direct substitution.

Q: Are there any temperature or environmental limitations affecting substitution?

A: Both parts operate across the identical temperature range of -55°C to 125°C (junction temperature). The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints. Environmental performance is equivalent.

Q: How should I select between USBQ50415CE3/TR7 and USBQNM50415CE3/TR7 for procurement?

A: Selection is based on inventory availability and lead time. The USBQNM50415CE3/TR7 currently maintains higher stock levels. For applications with no inventory constraints, either part is technically equivalent. Verify current availability with your supplier before finalizing procurement decisions.
