Q2010N4RP TRIAC Equivalent & Substitute Parts

Part Overview

The Q2010N4RP is a standard TRIAC manufactured by Littelfuse, rated for 200V off-state voltage and 10A on-state current in a Surface Mount TO-263 (D2PAK) package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. Substitute parts must maintain compatible electrical ratings and identical mechanical packaging to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Q2010N4RP is determined by the following critical parameters:

• Voltage Rating (Off State): The substitute must equal or exceed 200V to maintain voltage margin in the application circuit.
• Current Rating (On State): The substitute must equal or exceed 10A RMS to handle the specified load current.
• Gate Trigger Parameters: Vgt and Igt must remain within compatible ranges to ensure reliable gate drive circuit operation.
• Package Compatibility: The substitute must use TO-263-3 (D2PAK) packaging with identical lead configuration for PCB compatibility.
• Mounting Type: Surface Mount configuration is required for direct replacement.

The BT138B-600F,118 meets these substitution criteria with higher voltage and current ratings, providing design margin while maintaining the same package footprint and gate trigger characteristics.

Engineering Selection Recommendations

The BT138B-600F,118 is the qualified substitute for the Q2010N4RP based on the following factors:

• Product Status: The substitute is Active, ensuring continued availability and manufacturing support, whereas the main part is Obsolete.
• Compliance: Both parts maintain RoHS compliance, satisfying regulatory requirements for new designs and procurement.
• Electrical Compatibility: The substitute exceeds the main part specifications in voltage (600V vs. 200V) and current (12A vs. 10A) ratings, providing design margin without requiring circuit modification.
• Package Equivalence: Identical TO-263-3 (D2PAK) packaging ensures mechanical and electrical compatibility on existing PCBs.
• Gate Drive Compatibility: Gate trigger parameters remain within acceptable ranges for existing gate drive circuits.

Frequently Asked Questions (FAQ)

Q: Can the BT138B-600F,118 be used as a direct replacement for the Q2010N4RP?

A: Yes. Both components use identical TO-263-3 (D2PAK) packaging with the same lead configuration, allowing direct PCB substitution. The higher voltage and current ratings of the substitute provide additional design margin.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (600V vs. 200V), current rating (12A vs. 10A), and product status (Active vs. Obsolete). The substitute offers higher electrical ratings while maintaining compatible gate trigger characteristics and operating temperature range.

Q: Are there any circuit modifications required when switching to the BT138B-600F,118?

A: No circuit modifications are required. The substitute meets or exceeds all critical electrical parameters of the main part. Gate drive circuits designed for the Q2010N4RP will operate correctly with the BT138B-600F,118.

Q: Does the substitute maintain the same thermal characteristics?

A: Both parts operate across the same temperature range (-40°C to 125°C TJ). Thermal performance depends on application-specific factors such as heat dissipation design and load conditions.

Q: What is the moisture sensitivity level for the substitute?

A: The BT138B-600F,118 has a Moisture Sensitivity Level (MSL) of 1 (Unlimited), matching the main part specification.
