IRGC14C40LD Equivalent & Substitute Parts

Part Overview

The IRGC14C40LD is an Infineon Technologies IGBT designed for ignition applications, rated at 430 V collector-emitter breakdown voltage and 14 A maximum collector current. This component is supplied as a surface mount die package. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility within the specified voltage and current ratings while accommodating different package configurations available in active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRGC14C40LD is determined by the following critical electrical parameters:

• Voltage Rating: Substitute parts must support minimum 430 V collector-emitter breakdown voltage
• Current Rating: Substitute parts must support minimum 14 A collector current capacity
• Input Type: Logic-level gate drive compatibility required
• Operating Temperature: Thermal range -40°C to 175°C (TJ) must be maintained
• Regulatory Compliance: REACH and ECCN classifications must align with original specifications

The ISL9V3040D3ST meets these criteria with a 430 V voltage rating and 21 A current capacity, exceeding the minimum requirements of the IRGC14C40LD. The substitute part is available in an active product status with TO-252AA packaging, providing improved availability compared to the obsolete die package original.

Parameter Comparison

Engineering Selection Recommendations

The ISL9V3040D3ST is the qualified substitute for the IRGC14C40LD based on the following engineering criteria:

Electrical Compatibility: Both devices operate at identical 430 V breakdown voltage and -40°C to 175°C temperature range. The substitute's 21 A current rating provides operational margin above the original 14 A specification, ensuring thermal and electrical headroom in equivalent circuit designs.

Regulatory Alignment: Both parts maintain REACH Unaffected and EAR99 ECCN classifications, ensuring compliance with the same export and environmental standards as the original component.

Product Availability: The ISL9V3040D3ST holds active product status with 37,700 units in stock, compared to the obsolete IRGC14C40LD with limited remaining inventory. This ensures long-term supply continuity for production and design updates.

Package Consideration: The substitute transitions from die package to TO-252AA (DPAK) surface mount configuration. This change requires PCB layout modification but provides improved thermal management through the integrated tab structure and simplified assembly handling compared to bare die processing.

Frequently Asked Questions (FAQ)

Q: Can the ISL9V3040D3ST directly replace the IRGC14C40LD in existing designs?

A: Electrical substitution is valid based on matched voltage, current, temperature, and logic-level input specifications. However, PCB layout redesign is required due to package transition from die to TO-252AA. Gate drive timing and thermal management characteristics must be verified for the specific application circuit.

Q: What is the primary reason for substitution?

A: The IRGC14C40LD is classified as obsolete with limited inventory. The ISL9V3040D3ST provides equivalent electrical performance with active manufacturing status and significantly higher stock availability.

Q: Are there thermal performance differences between the two parts?

A: The ISL9V3040D3ST includes a thermal tab in the TO-252AA package, improving heat dissipation compared to the die package configuration. The Vce(on) specification of 1.6 V at 4V, 6A indicates lower on-state voltage characteristics, potentially reducing thermal load in equivalent current conditions.

Q: Does the higher current rating of the substitute affect circuit design?

A: The 21 A rating of the ISL9V3040D3ST exceeds the 14 A requirement of the original design. This provides operational margin and does not require circuit modification, as the device will operate within its rated specifications at the lower current demand.

Q: Are compliance certifications maintained with the substitute?

A: Yes. Both the IRGC14C40LD and ISL9V3040D3ST maintain identical REACH Unaffected and EAR99 ECCN classifications, ensuring regulatory compliance equivalence.

Q: What packaging considerations apply to the ISL9V3040D3ST?

A: The ISL9V3040D3ST is supplied in TO-252AA (DPAK) surface mount package with Cut Tape and Digi-Reel options. This standard package format simplifies procurement and assembly compared to bare die handling requirements of the original component.
