IRG4PSC71UDPBF IGBT Equivalent & Substitute Parts

Part Overview

The IRG4PSC71UDPBF is a 600V, 85A IGBT manufactured by Infineon Technologies in the SUPER-247™ (TO-274AA) package. This component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRG4PSC71UDPBF is determined by the following critical electrical and mechanical parameters:

Voltage Rating: The substitute part must operate at or above 600V collector-emitter breakdown voltage to ensure safe operation in the original circuit topology.

Current Rating: The substitute part must support a minimum collector current (Ic) rating that meets or exceeds the 85A requirement of the main part.

Pulsed Current: The substitute part must accommodate the 200A pulsed collector current specification.

Package Compatibility: The substitute part must use a through-hole mounting configuration compatible with TO-247 series packages to ensure PCB footprint compatibility.

Thermal Performance: The substitute part must maintain an operating temperature range that encompasses the original specification range of -55°C to 150°C.

Compliance: Both parts must maintain ROHS3 compliance and REACH unaffected status for regulatory alignment.

The IKW50N65ES5XKSA1 meets these substitution criteria with a 650V rating, 80A collector current, 200A pulsed current capability, and TO-247-3 through-hole package configuration.

Parameter Comparison

Engineering Selection Recommendations

The IKW50N65ES5XKSA1 is designated as an active product with current manufacturing status, whereas the IRG4PSC71UDPBF is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production continuity.

The substitute part provides a 650V voltage rating, which exceeds the 600V requirement of the main part, offering improved voltage margin. The 80A collector current rating is within 94% of the original 85A specification. Pulsed current capability remains identical at 200A.

The TO-247-3 package of the substitute part is mechanically compatible with TO-274AA footprints in through-hole applications, though PCB layout verification is required to confirm exact pin alignment and thermal pad positioning.

The substitute part exhibits lower gate charge (120nC versus 340nC) and faster switching characteristics, which may alter circuit timing behavior in gate drive circuits. The operating temperature range of -40°C to 175°C encompasses the original -55°C to 150°C specification, with extended high-temperature capability.

Frequently Asked Questions (FAQ)

Q: Can the IKW50N65ES5XKSA1 directly replace the IRG4PSC71UDPBF in existing PCB designs?

A: The TO-247-3 package is mechanically compatible with TO-274AA through-hole mounting. However, thermal pad dimensions and pin spacing must be verified against the original PCB layout to ensure proper fit and thermal performance.

Q: What are the key electrical differences between these parts?

A: The substitute part provides 50V higher voltage rating (650V versus 600V), 5A lower collector current rating (80A versus 85A), significantly lower gate charge (120nC versus 340nC), and faster switching times. These differences may affect circuit performance in high-frequency applications and gate drive requirements.

Q: Are both parts compliant with current regulatory standards?

A: Both the IRG4PSC71UDPBF and IKW50N65ES5XKSA1 maintain ROHS3 compliance and REACH unaffected status. The substitute part's active product status ensures continued compliance with evolving regulatory requirements.

Q: What is the impact of the lower gate charge on circuit design?

A: Lower gate charge (120nC) reduces gate drive power requirements and switching losses compared to the main part (340nC). Gate drive circuits designed for the original part may require adjustment to optimize switching performance with the substitute part.

Q: How do the operating temperature ranges compare?

A: The substitute part extends the maximum junction temperature to 175°C compared to 150°C for the main part. The minimum operating temperature for the substitute is -40°C versus -55°C for the main part. Applications requiring operation below -40°C require design verification.

Q: Is the power dissipation rating sufficient for the original application?

A: The substitute part has a maximum power rating of 274W compared to 350W for the main part. Applications operating near the 350W limit require thermal analysis to confirm the substitute part can dissipate the required power within the specified operating temperature range.
