IRF630STRL Equivalent & Substitute Parts

Part Overview

The IRF630STRL is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 200V drain-to-source voltage with 9A continuous drain current in a surface mount TO-263 (D2PAK) package. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement.

The IRF630STRL serves in switching and amplification applications requiring moderate voltage and current handling in compact surface mount form factors. Due to its obsolete status, equivalent parts with active product status or improved electrical characteristics are available as direct replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRF630STRL is determined by the following critical parameters:

Voltage Rating: All substitute parts maintain the 200V Vdss specification, ensuring compatibility in circuits designed for this voltage class.

Package Type: All substitutes use the TO-263 (D2PAK) surface mount package, maintaining mechanical and thermal interface compatibility.

Current Handling: Substitute parts range from 9A to 15A continuous drain current. Parts rated at or above 9A are electrically compatible for the IRF630STRL application.

On-State Resistance (Rds On): Substitute parts with equal or lower Rds On values provide equivalent or improved performance. The IRF630STRL specifies 400 mOhm; substitutes with 300 mOhm or lower represent performance improvements.

Gate Charge (Qg): Lower gate charge values indicate faster switching characteristics. Substitutes with reduced Qg improve switching speed and reduce drive circuit losses.

RoHS Compliance: The IRF630STRL is RoHS non-compliant. Active substitute parts are ROHS3 compliant, meeting current environmental regulations.

Product Status: Active status substitutes ensure long-term availability and supply chain continuity compared to the obsolete IRF630STRL.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Vishay Siliconix):

IRF630STRLPBF and IRF630STRRPBF are parametric equivalents of the IRF630STRL with identical electrical specifications. Both are manufactured by Vishay Siliconix and maintain the same 200V/9A rating and 400 mOhm on-state resistance. The primary distinction is packaging format: IRF630STRLPBF is supplied in Tape & Reel (TR) format, while IRF630STRRPBF is also supplied in Tape & Reel (TR) format. Both parts carry ROHS3 compliance and active product status, providing superior supply chain continuity compared to the obsolete IRF630STRL.

Performance-Enhanced Substitutes:

IRF630NSTRLPBF (Infineon Technologies) provides improved electrical characteristics with 9.3A current rating, reduced on-state resistance of 300 mOhm, and lower gate charge of 35 nC. This part extends the operating temperature range to 175°C. Despite obsolete status, it represents a performance upgrade path.

RCJ120N20TL (Rohm Semiconductor) offers the highest current rating at 12A with 325 mOhm on-state resistance and significantly reduced gate charge of 15 nC. This part is active and ROHS3 compliant, making it suitable for applications requiring improved switching performance and higher current capacity.

STB19NF20 (STMicroelectronics) provides the highest current rating at 15A with the lowest on-state resistance of 160 mOhm and gate charge of 24 nC. This part is active, ROHS3 compliant, and offers the best thermal performance characteristics for power dissipation-critical applications.

Compliance Consideration:

All substitute parts except IRF630NSTRLPBF are ROHS3 compliant and carry active product status. For new designs and long-term production, IRF630STRLPBF, RCJ120N20TL, or STB19NF20 are recommended based on current and thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can IRF630STRLPBF directly replace IRF630STRL in existing designs?

A: Yes. IRF630STRLPBF is a parametric equivalent with identical electrical specifications (200V, 9A, 400 mOhm Rds On). The primary difference is ROHS3 compliance and active product status. Mechanical compatibility is maintained through identical TO-263 (D2PAK) packaging.

Q: What is the difference between IRF630STRLPBF and IRF630STRRPBF?

A: Both parts are parametric equivalents with identical electrical specifications. The difference lies in packaging format: IRF630STRLPBF is supplied in Tape & Reel (TR) format, and IRF630STRRPBF is also supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly requirements.

Q: Can I use RCJ120N20TL as a substitute for IRF630STRL?

A: Yes, with design verification. RCJ120N20TL maintains the 200V voltage rating and TO-263 package compatibility. It provides higher current capacity (12A vs. 9A) and improved switching characteristics (15 nC gate charge vs. 43 nC). The LPTS package variant maintains mechanical compatibility with D2PAK footprints. Verify gate threshold voltage (5.25V vs. 4V) compatibility with drive circuits.

Q: What are the advantages of STB19NF20 over IRF630STRL?

A: STB19NF20 offers superior performance across multiple parameters: 15A current rating (vs. 9A), 160 mOhm on-state resistance (vs. 400 mOhm), and 24 nC gate charge (vs. 43 nC). These improvements reduce conduction losses and switching losses. STB19NF20 is active and ROHS3 compliant, ensuring long-term availability. The D2PAK package maintains mechanical compatibility.

Q: Is the operating temperature range difference between IRF630STRL and IRF630NSTRLPBF significant?

A: IRF630NSTRLPBF extends the maximum junction temperature to 175°C compared to 150°C for IRF630STRL. This provides additional thermal margin in high-temperature applications. However, IRF630NSTRLPBF carries obsolete status, limiting its suitability for new designs despite superior thermal specifications.

Q: How does gate charge affect circuit performance?

A: Gate charge (Qg) determines the energy required to switch the MOSFET on and off. Lower gate charge reduces drive circuit losses and enables faster switching. RCJ120N20TL (15 nC) and STB19NF20 (24 nC) provide significantly faster switching compared to IRF630STRL (43 nC), reducing electromagnetic interference and improving efficiency in switching applications.

Q: Are all substitute parts RoHS compliant?

A: IRF630STRLPBF, IRF630STRRPBF, RCJ120N20TL, and STB19NF20 are ROHS3 compliant. IRF630NSTRLPBF is also ROHS3 compliant. The original IRF630STRL is RoHS non-compliant. For applications requiring environmental compliance, select from the ROHS3 compliant alternatives.

Q: Can I use a higher-rated part like STB19NF20 (15A) in place of IRF630STRL (9A)?

A: Yes. Higher current-rated parts are electrically compatible for applications designed for lower current. STB19NF20 provides improved performance margins and thermal characteristics. Verify that the lower on-state resistance (160 mOhm vs. 400 mOhm) does not introduce unintended circuit behavior changes, particularly in current-limiting or sensing circuits.

Q: What packaging considerations apply to these substitutes?

A: All substitutes use TO-263 (D2PAK) or compatible surface mount packages. RCJ120N20TL uses LPTS packaging, which maintains mechanical and thermal interface compatibility with D2PAK footprints. Verify PCB layout and thermal management provisions accommodate the selected part's power dissipation characteristics.
