Substitute Part Grouping Explanation

Substitution of the IRF6623 MOSFET is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Must Match):

• FET Type: N-Channel
• Drain to Source Voltage (Vdss): 20V
• Continuous Drain Current (Id): 16A (Ta), 55A (Tc)
• On-State Resistance (Rds On): 5.7 mOhm @ 15A, 10V
• Gate Threshold Voltage (Vgs(th)): 2.2V @ 250µA
• Gate Charge (Qg): 17 nC @ 4.5V
• Input Capacitance (Ciss): 1360 pF @ 10V
• Power Dissipation: 1.4W (Ta), 42W (Tc)
• Operating Temperature Range: -40°C to 150°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: DirectFET™ Isometric ST
• Series: HEXFET®

The IRF6623TRPBF is identified as a parametric equivalent based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between the main part and this substitute is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Engineering Selection Recommendations

IRF6623TRPBF as Primary Substitute:

The IRF6623TRPBF is a direct parametric equivalent to the IRF6623. All electrical characteristics, thermal ratings, and mechanical specifications are identical. This substitute is recommended for new designs and ongoing production support due to the following factors:

1. Product Status: The IRF6623TRPBF maintains Active product status, ensuring long-term availability and continued manufacturer support, whereas the IRF6623 is Obsolete.

2. Regulatory Compliance: The IRF6623TRPBF is ROHS3 Compliant, meeting current environmental and regulatory requirements. The original IRF6623 is RoHS non-compliant.

3. Moisture Sensitivity: The IRF6623TRPBF carries MSL 1 (Unlimited), providing superior moisture tolerance compared to the IRF6623 MSL 3 (168 Hours). This reduces handling and storage constraints.

4. Packaging Format: The IRF6623TRPBF is supplied in Tape & Reel format, which is standard for automated assembly processes and high-volume production environments.

5. Electrical Equivalence: Complete parameter alignment ensures drop-in compatibility without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the IRF6623TRPBF be used as a direct replacement for the IRF6623 in existing designs?

A: Yes. The IRF6623TRPBF is electrically and mechanically identical to the IRF6623. All drain current ratings, on-state resistance, gate charge, capacitance, and thermal specifications match exactly. The component can be substituted without circuit modification.

Q: What is the primary difference between the IRF6623 and IRF6623TRPBF?

A: The primary differences are packaging format (Tape & Reel versus bulk), product status (Active versus Obsolete), RoHS compliance (ROHS3 Compliant versus non-compliant), and moisture sensitivity level (MSL 1 versus MSL 3). Electrical performance is identical.

Q: Why is the IRF6623 listed as Obsolete?

A: The IRF6623 has reached end-of-life status with Infineon Technologies. The IRF6623TRPBF, which shares identical electrical specifications, remains in active production and is the recommended long-term solution.

Q: Are there any thermal performance differences between these parts?

A: No. Both parts have identical power dissipation ratings of 1.4W (Ta) and 42W (Tc), and both operate across the same temperature range of -40°C to 150°C (TJ).

Q: Does the Tape & Reel packaging of the IRF6623TRPBF affect electrical performance?

A: No. Packaging format does not affect electrical characteristics. Tape & Reel packaging is a delivery and handling format optimized for automated assembly processes and does not alter device performance.

Q: Is the IRF6623TRPBF suitable for high-volume production?

A: Yes. The Tape & Reel format, Active product status, and improved moisture sensitivity level (MSL 1) make the IRF6623TRPBF well-suited for high-volume manufacturing environments.

Q: What does ROHS3 Compliance mean for the IRF6623TRPBF?

A: ROHS3 Compliance indicates that the IRF6623TRPBF meets the Restriction of Hazardous Substances Directive 3, restricting the use of specific hazardous materials in electrical and electronic equipment. This is a regulatory requirement in many markets.

Q: Can I mix IRF6623 and IRF6623TRPBF components in the same production batch?

A: While electrically equivalent, mixing components with different RoHS compliance statuses and moisture sensitivity levels may create supply chain and documentation complications. Standardizing on the IRF6623TRPBF is recommended for consistency.
