IRL630 Equivalent & Substitute Parts

Part Overview

The IRL630 is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 200V drain-to-source voltage with 9A continuous drain current in a Through Hole TO-220AB package. This device is classified as Obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement continuity. The IRL630 is suitable for switching applications requiring moderate voltage and current ratings with thermal dissipation up to 74W.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRL630 is determined by electrical and mechanical parameter equivalence within the N-Channel MOSFET category. The critical parameters governing substitution are:

• Drain to Source Voltage (Vdss): 200V minimum
• Continuous Drain Current (Id): 9A minimum at 25°C
• On-State Resistance (Rds On): 400 mOhm maximum at specified gate voltage
• Power Dissipation: 74W minimum thermal rating
• Package Type: TO-220-3 Through Hole configuration
• Operating Temperature Range: -55°C to 150°C minimum

Substitute parts must meet or exceed these electrical specifications and maintain identical mechanical packaging to ensure direct replacement capability in existing circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

IRL630PBF is the primary direct substitute for the IRL630. Both components are manufactured by Vishay Siliconix and share identical electrical specifications across all critical parameters including Vdss, Id, Rds On, gate charge, and input capacitance. The IRL630PBF is classified as Active product status, ensuring continued availability and supply chain support. The IRL630PBF achieves ROHS3 compliance, whereas the original IRL630 is RoHS non-compliant. Both devices are packaged in TO-220-3 configuration and support the same operating temperature range. The IRL630PBF is supplied in Tube packaging.

IRF630 is an alternative substitute manufactured by Harris Corporation. This device meets the core electrical requirements of 200V Vdss, 9A continuous drain current, and 74W power dissipation in TO-220-3 package. However, the IRF630 exhibits differences in gate threshold voltage (Vgs(th) of 4V versus 2V) and input capacitance (800 pF versus 1100 pF). The IRF630 is classified as Obsolete. These parameter variations may affect gate drive circuit design and switching characteristics in applications sensitive to threshold voltage or input capacitance values.

Selection between IRL630PBF and IRF630 should be based on product availability requirements, RoHS compliance mandates, and circuit sensitivity to threshold voltage and capacitance parameters.

Frequently Asked Questions (FAQ)

Q: Can IRL630PBF be used as a direct replacement for IRL630?

A: Yes. The IRL630PBF is a direct substitute. Both components share identical electrical specifications for Vdss (200V), Id (9A), Rds On (400 mOhm @ 5.4A, 5V), gate charge (40 nC @ 10V), and input capacitance (1100 pF @ 25V). Both are manufactured by Vishay Siliconix in TO-220-3 package. The primary difference is product status (IRL630PBF is Active) and RoHS compliance (IRL630PBF is ROHS3 compliant).

Q: What are the key differences between IRL630 and IRF630?

A: Both devices share the same Vdss (200V), Id (9A), and power dissipation (74W) ratings in TO-220-3 package. The IRF630 differs in gate threshold voltage (Vgs(th) of 4V @ 250µA versus 2V @ 250µA for IRL630) and input capacitance (800 pF @ 25V versus 1100 pF @ 25V). The IRF630 also requires 10V gate voltage for Rds On specification versus 5V for IRL630. These differences affect gate drive requirements and switching speed characteristics.

Q: Are there packaging differences between these substitutes?

A: All three devices (IRL630, IRL630PBF, and IRF630) use TO-220-3 Through Hole package configuration. The IRL630PBF is supplied in Tube packaging, while packaging information for IRL630 and IRF630 is not specified in the provided data. The mechanical footprint and pin configuration are identical across all three devices.

Q: Which substitute should be selected for new designs?

A: IRL630PBF is the recommended selection for new designs. It maintains full electrical equivalence to the IRL630 while offering Active product status and ROHS3 compliance. This ensures long-term availability and regulatory compliance for applications subject to RoHS requirements.

Q: Can IRF630 be used if IRL630PBF is unavailable?

A: IRF630 is functionally compatible for applications where the gate threshold voltage difference (4V versus 2V) and input capacitance difference (800 pF versus 1100 pF) do not impact circuit performance. Gate drive circuits designed for 5V operation may require adjustment for the IRF630's 4V threshold specification. Switching speed may differ due to the lower input capacitance of the IRF630.

Q: What is the operating temperature range for these devices?

A: All three devices operate across the temperature range of -55°C to 150°C (TJ), providing equivalent thermal performance specifications.

Q: Are there RoHS compliance considerations for substitute selection?

A: The original IRL630 is RoHS non-compliant. The IRL630PBF is ROHS3 compliant, making it suitable for applications subject to RoHS directives. The IRF630 is RoHS non-compliant. For applications requiring RoHS compliance, IRL630PBF is the appropriate selection.
