Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRF1324LPBF is evaluated based on the following critical parameters:

Electrical Compatibility Criteria:

• FET Type: N-Channel topology must be maintained
• Drain to Source Voltage (Vdss): Substitute must equal or exceed 24V rating
• Current - Continuous Drain (Id): Substitute must support minimum 195A continuous current
• Power Dissipation: Substitute must support minimum 300W thermal capability
• On-State Resistance (Rds On): Substitute performance at specified gate voltage and current
• Operating Temperature Range: Substitute must cover -55°C to 175°C (TJ)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole configuration required
• Package / Case: TO-262-3 Long Leads, I2PAK, or TO-262AA package family

The AUIRF2804L qualifies as a direct substitute based on these parameters. While the AUIRF2804L features a higher Vdss rating (40V versus 24V), this represents an upward-compatible specification that does not compromise circuit functionality. Both devices maintain identical continuous drain current (195A), identical power dissipation capability (300W), identical package configuration (TO-262), and identical operating temperature range (-55°C to 175°C).

Parameter Comparison

Engineering Selection Recommendations

The AUIRF2804L is the qualified substitute for the obsolete IRF1324LPBF based on the following engineering factors:

Product Status Alignment: The IRF1324LPBF is classified as obsolete, creating supply chain risk for new designs and ongoing production. The AUIRF2804L maintains active product status with Infineon Technologies, ensuring continued availability and manufacturing support.

Electrical Parameter Compatibility: Both devices are manufactured by Infineon Technologies within the HEXFET® series. The AUIRF2804L maintains identical continuous drain current (195A), identical power dissipation capability (300W), and identical operating temperature range (-55°C to 175°C). The higher Vdss rating (40V versus 24V) on the AUIRF2804L provides enhanced voltage margin without degrading performance in 24V applications.

Compliance and Certification: The AUIRF2804L carries RoHS3 compliance certification, whereas the IRF1324LPBF compliance status is not specified. Both devices are REACH Unaffected and carry identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications.

Package and Mounting Compatibility: Both devices utilize identical TO-262-3 Long Leads, I2PAK, TO-262AA package configurations with through-hole mounting, ensuring direct mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the AUIRF2804L directly replace the IRF1324LPBF in existing designs?

A: Yes. Both devices share identical continuous drain current (195A), power dissipation (300W), gate charge (240 nC @ 10V), threshold voltage (4V @ 250µA), and operating temperature range (-55°C to 175°C). The TO-262 package configuration is identical, enabling direct PCB compatibility. The higher Vdss rating (40V) on the AUIRF2804L does not create functional incompatibility in 24V applications.

Q: What is the significance of the higher Vdss rating on the AUIRF2804L?

A: The AUIRF2804L features a 40V Vdss rating compared to the IRF1324LPBF's 24V rating. This represents an upward-compatible specification that provides additional voltage margin. In applications operating at 24V or below, the higher Vdss rating does not degrade performance and may provide enhanced reliability through increased voltage headroom.

Q: Are there differences in on-state resistance between these devices?

A: The IRF1324LPBF specifies Rds On (Max) of 1.65 mOhm @ 195A, 10V. The AUIRF2804L specifies Rds On (Max) of 2 mOhm @ 75A, 10V. These specifications are measured at different current levels. At the full 195A continuous current rating, both devices are designed to operate within their respective thermal and electrical specifications.

Q: What is the package compatibility between these devices?

A: Both the IRF1324LPBF and AUIRF2804L utilize the TO-262-3 Long Leads, I2PAK, TO-262AA package configuration. This ensures identical pin spacing, lead geometry, and through-hole mounting compatibility. No PCB layout modifications are required for substitution.

Q: Why is the IRF1324LPBF classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, technology evolution, and production decisions. The IRF1324LPBF has been superseded by newer designs such as the AUIRF2804L, which maintains equivalent electrical performance while offering active product status and continued manufacturing support.

Q: Are there compliance differences between the IRF1324LPBF and AUIRF2804L?

A: The AUIRF2804L carries explicit RoHS3 compliance certification. Both devices are REACH Unaffected and share identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications. For applications requiring RoHS compliance documentation, the AUIRF2804L provides certified compliance status.

Q: Can the AUIRF2804L be used in high-temperature applications?

A: Yes. The AUIRF2804L maintains the identical operating temperature range as the IRF1324LPBF: -55°C to 175°C (TJ). Both devices are rated for the full temperature spectrum without derating.
