IRF630NSTRLPBF N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRF630NSTRLPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 200V drain-to-source voltage with 9.3A continuous drain current at 25°C. This device is packaged in D2PAK (TO-263-3) surface mount configuration and belongs to the HEXFET® series. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, and thermal characteristics while accommodating available packaging and product status options.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

IRF630SPBF, IRF630STRLPBF, and IRF630STRRPBF are direct electrical equivalents manufactured by Vishay Siliconix. All three maintain the 200V/9A rating and D2PAK package configuration. These parts are classified as Active products, ensuring long-term availability and supply chain stability. The primary difference is packaging format: IRF630SPBF is supplied in Tube packaging, while IRF630STRLPBF and IRF630STRRPBF are supplied in Tape & Reel format. Selection between these three should be based on procurement requirements and assembly line compatibility. All three are ROHS3 compliant with MSL 1 rating.

Secondary Substitutes (Enhanced Performance):

STB19NF20 (STMicroelectronics) provides superior electrical performance with 15A continuous drain current and significantly lower on-resistance (160mOhm vs. 300mOhm). This part maintains 200V Vdss rating and D2PAK packaging. The enhanced current handling and reduced on-resistance result in lower power dissipation (90W Tc), making it suitable for applications requiring improved thermal performance. Operating temperature range is -55°C to 150°C, which is 25°C lower than the main part. This part is Active status and ROHS3 compliant.

RCJ120N20TL (Rohm Semiconductor) offers 12A continuous drain current with 325mOhm on-resistance. This part uses LPTS package format rather than standard D2PAK, requiring PCB layout verification for mechanical compatibility. Gate charge is significantly lower (15nC vs. 35nC), which may affect gate drive circuit design. Operating temperature maximum is 150°C. This part is Active status and ROHS3 compliant.

Selection Criteria:

For direct replacement with minimal design changes: Select IRF630SPBF, IRF630STRLPBF, or IRF630STRRPBF based on packaging format availability
For improved thermal performance and current margin: Select STB19NF20
For reduced gate charge and lower current applications: Select RCJ120N20TL with package compatibility verification

All substitute parts are ROHS3 compliant and carry MSL 1 moisture sensitivity rating, meeting standard industrial compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can IRF630SPBF directly replace IRF630NSTRLPBF without PCB modifications?

A: IRF630SPBF is electrically compatible and uses the same D2PAK package. The primary difference is packaging format (Tube vs. Cut Tape). No PCB modifications are required. Verify that your assembly process accommodates tube-packaged components.

Q: What is the difference between IRF630STRLPBF and IRF630STRRPBF?

A: Both parts are electrically identical with 200V/9A ratings and D2PAK packaging. The difference is in tape reel configuration: STRLPBF uses standard tape & reel, while STRRPBF uses alternative reel specifications. Selection depends on your pick-and-place equipment compatibility. Consult equipment documentation for reel format requirements.

Q: Why does STB19NF20 have lower on-resistance than the main part?

A: STB19NF20 is rated for 15A continuous drain current compared to 9.3A for IRF630NSTRLPBF. Higher current-rated MOSFETs typically feature lower on-resistance to manage power dissipation. This provides improved performance margins in applications operating near the 9.3A specification.

Q: Is RCJ120N20TL package compatible with IRF630NSTRLPBF PCB layouts?

A: RCJ120N20TL uses LPTS package format instead of standard D2PAK. While both are surface mount configurations, pin spacing and footprint dimensions differ. PCB layout verification is required before substitution. Contact the component supplier for detailed package dimensions.

Q: What is the operating temperature limitation when substituting with active parts?

A: IRF630NSTRLPBF operates to 175°C junction temperature. Substitute parts IRF630SPBF, IRF630STRLPBF, IRF630STRRPBF, RCJ120N20TL, and STB19NF20 all operate to 150°C maximum. Applications requiring operation above 150°C junction temperature cannot use these substitutes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. IRF630SPBF, IRF630STRLPBF, IRF630STRRPBF, RCJ120N20TL, and STB19NF20 are all ROHS3 compliant with MSL 1 moisture sensitivity rating, meeting standard industrial compliance requirements.

Q: Can I use STB19NF20 in a circuit designed for 9.3A operation?

A: Yes. STB19NF20 is rated for 15A continuous drain current, which exceeds the 9.3A requirement. The part maintains 200V Vdss and compatible gate threshold voltage. Lower on-resistance (160mOhm) reduces power dissipation, improving thermal performance. No circuit modifications are required for current-limited applications.

Q: What does "Active" product status mean for long-term availability?

A: Active status indicates the manufacturer continues production and supports the part through normal distribution channels. IRF630NSTRLPBF is classified as Obsolete, meaning Infineon no longer manufactures it. All recommended substitutes are Active status, ensuring availability for future procurement and design revisions.
