FQP7N10 Equivalent & Substitute Parts

Part Overview

The FQP7N10 is an N-Channel MOSFET manufactured by onsemi, rated for 100V drain-to-source voltage and 7.3A continuous drain current in a Through Hole TO-220-3 package. This device is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates across a temperature range of -55°C to 175°C and dissipates up to 40W, making it suitable for general-purpose switching and amplification applications in power electronics.

Substitute Part Grouping Explanation

Substitution of the FQP7N10 is determined by electrical and mechanical compatibility within the N-Channel MOSFET category. The primary substitution criteria are:

Electrical Compatibility:

• Drain-to-Source Voltage (Vdss) must equal or exceed 100V
• Continuous Drain Current (Id) must equal or exceed 7.3A
• Drive Voltage (Max Rds On) must be compatible at 10V
• Power Dissipation (Max) must support 40W operation
• Gate-Source Voltage (Vgs Max) must accommodate ±25V or greater

Mechanical Compatibility:

• Package must be Through Hole TO-220 variant (TO-220-3 or TO-220FM)
• Mounting configuration must support direct board-level installation

Compliance & Status:

• REACH compliance status must be equivalent or compliant
• Moisture Sensitivity Level (MSL) must be 1 (Unlimited) or equivalent

The RCX100N25 meets these criteria with enhanced electrical ratings and active product status.

Engineering Selection Recommendations

The RCX100N25 is a direct substitute for the FQP7N10 based on the following engineering criteria:

Electrical Sufficiency: The RCX100N25 exceeds the electrical requirements of the FQP7N10. With a Vdss rating of 250V (versus 100V), continuous drain current of 10A (versus 7.3A), and identical 40W power dissipation, the substitute part operates within all specified electrical parameters. The 10V drive voltage and ±30V gate-source voltage rating provide full compatibility with the original design specifications.

Mechanical Compatibility: Both devices utilize Through Hole mounting in TO-220 package variants (TO-220-3 and TO-220FM). These packages are mechanically and electrically interchangeable at the board level, requiring no PCB redesign or mechanical modification.

Compliance & Availability: The RCX100N25 holds Active product status from Rohm Semiconductor, ensuring long-term availability and supply chain continuity. Both parts maintain REACH Unaffected status and MSL 1 (Unlimited) classification, confirming equivalent environmental and handling compliance.

Obsolescence Mitigation: The FQP7N10 is classified as Obsolete. The RCX100N25 provides a viable path for design refresh and procurement continuity without requiring circuit redesign, as all critical electrical and mechanical parameters are met or exceeded.

Frequently Asked Questions (FAQ)

Q: Can the RCX100N25 be used as a direct replacement for the FQP7N10 without circuit modification?

A: Yes. The RCX100N25 meets or exceeds all electrical parameters of the FQP7N10, including Vdss, Id, drive voltage, and power dissipation. The TO-220 package variants are mechanically interchangeable. No circuit modification is required.

Q: What is the primary advantage of the RCX100N25 over the FQP7N10?

A: The RCX100N25 offers higher voltage rating (250V versus 100V) and higher current rating (10A versus 7.3A), providing design margin for applications requiring enhanced electrical performance. Additionally, the RCX100N25 maintains Active product status, ensuring long-term availability.

Q: Are the TO-220-3 and TO-220FM packages pin-compatible?

A: Yes. Both TO-220-3 and TO-220FM are Through Hole TO-220 package variants with identical pin configurations and board-level mounting requirements. They are mechanically and electrically interchangeable.

Q: What compliance certifications apply to both parts?

A: Both the FQP7N10 and RCX100N25 maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited), confirming equivalent environmental and handling compliance for industrial applications.

Q: Why is the FQP7N10 classified as Obsolete?

A: Obsolete status indicates that onsemi has discontinued active production and support for this part. The RCX100N25 provides a substitute path for ongoing design support and procurement continuity.

Q: Are there any thermal or operating temperature differences between the two parts?

A: The FQP7N10 operates across -55°C to 175°C. The RCX100N25 specifies 150°C maximum junction temperature. For applications requiring the full -55°C to 175°C range, thermal analysis is required to confirm the RCX100N25 operates within acceptable limits under worst-case conditions.
