IRF7316PBF Equivalent & Substitute Parts

Part Overview

The IRF7316PBF is a dual P-channel MOSFET array manufactured by Infineon Technologies, designed for surface mount applications requiring 30V operation and 4.9A continuous drain current. This component is part of the HEXFET® series and features logic level gate operation suitable for low-voltage switching applications.

The IRF7316PBF is currently discontinued at DiGi Electronics. Equivalent and substitute parts are available from alternative manufacturers to maintain design continuity and ensure supply chain availability. Substitute selection must be based on matching electrical characteristics, package compatibility, and operational parameters within specified tolerances.

Substitute Part Grouping Explanation

Substitute parts for the IRF7316PBF are selected based on the following criteria:

Mandatory Matching Parameters:

• Drain to Source Voltage (Vdss): 30V
• Configuration: 2 P-Channel (Dual)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• FET Feature: Logic Level Gate
• Operating Temperature Range: -55°C to 150°C (TJ)
• Technology: MOSFET (Metal Oxide)
• Mounting Type: Surface Mount

Allowable Parameter Variations: Substitute parts may exceed the IRF7316PBF specifications in the following parameters without compromising compatibility:

• Current - Continuous Drain (Id): Substitute parts with higher ratings (6A or 4.4A) are acceptable
• Rds On (Max): Lower on-resistance values indicate improved performance
• Power - Max: Higher power dissipation ratings provide additional thermal margin
• Gate Charge (Qg): Lower values reduce switching losses
• Input Capacitance (Ciss): Variations within the specified range are acceptable

Compliance Requirements: All substitute parts must maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status to ensure regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

FDS6975 (onsemi): The FDS6975 is an active product with higher continuous drain current (6A) and lower on-resistance (32mOhm), providing improved performance margin over the IRF7316PBF. This part is suitable for applications where enhanced current handling and reduced power dissipation are beneficial. The FDS6975 maintains full ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. Higher inventory availability (28,657 pcs) ensures supply continuity.

DMP3098LSD-13 (Diodes Incorporated): The DMP3098LSD-13 is an active product with continuous drain current of 4.4A, closely matching the IRF7316PBF specification. This part provides the most direct electrical equivalence with minimal parameter deviation. The DMP3098LSD-13 maintains full ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. Adequate inventory availability (25,300 pcs) supports production requirements.

Both substitute parts are electrically compatible with the IRF7316PBF within the specified operating parameters and maintain identical package geometry, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the FDS6975 be used as a direct replacement for the IRF7316PBF?

A: Yes. The FDS6975 meets all mandatory matching parameters: 30V Vdss, dual P-channel configuration, 8-SOIC package, logic level gate operation, and identical operating temperature range. The higher current rating (6A vs. 4.9A) and lower on-resistance (32mOhm vs. 58mOhm) represent performance improvements rather than incompatibilities.

Q: Can the DMP3098LSD-13 be used as a direct replacement for the IRF7316PBF?

A: Yes. The DMP3098LSD-13 meets all mandatory matching parameters: 30V Vdss, dual P-channel configuration, 8-SOIC package, logic level gate operation, and identical operating temperature range. The 4.4A continuous drain current closely matches the original 4.9A specification.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (0.154", 3.90mm Width) package ensures mechanical and electrical compatibility with existing PCB layouts. All substitute parts use identical package geometry, enabling direct component substitution without PCB redesign or rerouting.

Q: Are there differences in gate charge between the substitute parts?

A: Yes. The IRF7316PBF specifies 34nC @ 10V, the FDS6975 specifies 20nC @ 5V, and the DMP3098LSD-13 specifies 7.8nC @ 10V. Lower gate charge values reduce switching losses and improve switching speed. These variations are acceptable within the substitution criteria.

Q: Do all parts maintain the same compliance certifications?

A: Yes. The IRF7316PBF, FDS6975, and DMP3098LSD-13 are all ROHS3 compliant, MSL Level 1 rated, and REACH unaffected. Regulatory and environmental compliance is maintained across all substitute options.

Q: What is the difference between the IRF7316PBF and its base product number IRF731?

A: The IRF7316PBF is a dual P-channel array variant of the IRF731 series. The base product number indicates the device family; the full part number specifies the exact configuration and packaging.

Q: Can the substitute parts handle the same power dissipation as the IRF7316PBF?

A: The IRF7316PBF is rated for 2W maximum power dissipation. The FDS6975 is rated for 0.9W and the DMP3098LSD-13 is rated for 1.8W. Application-specific thermal analysis is required to confirm adequate power dissipation capability for the intended circuit.
