Engineering Selection Recommendations

For New Designs: Select from parts with Active product status: FDS6690A (onsemi), DMN3016LSS-13 (Diodes Incorporated), or RXH125N03TB1 (Rohm Semiconductor). These parts ensure long-term availability and manufacturer support. FDS6690A provides the closest electrical match to the IRF8707GPBF with identical 11A drain current rating and 2.5W power dissipation, combined with Active product status and ROHS3 compliance.

For Field Replacement or Legacy Support: Parts marked "Not For New Designs" (AO4468, STS10N3LH5) are acceptable for replacement applications where the original IRF8707GPBF is no longer available. These parts maintain electrical compatibility within specified parameter ranges.

Compliance Considerations: All substitute parts listed carry either ROHS3 Compliant or REACH Unaffected status, meeting current regulatory requirements. Selection should align with your manufacturing and supply chain compliance requirements.

Thermal Management: DMN3016LSS-13 offers the lowest power dissipation at 1.5W, suitable for thermally constrained applications. RXH125N03TB1 provides the highest drain current rating (12.5A) with 2W dissipation, offering thermal margin for high-current applications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace IRF8707GPBF with any of these substitute parts?

A: Yes, all listed substitute parts are electrically and mechanically compatible. They share identical 30V Vdss rating, 8-SOIC package configuration, and surface mount mounting type. Drain current ratings range from 10A to 12.5A, all within acceptable operating parameters for the IRF8707GPBF application envelope.

Q: What is the difference between 8-SO and 8-SOIC packaging?

A: The IRF8707GPBF is specified as 8-SO, while substitute parts use 8-SOIC designation. Both refer to the same 8-pin Small Outline Integrated Circuit package with 0.154" (3.90mm) width. These are mechanically and electrically interchangeable in PCB layouts designed for standard 8-SOIC footprints.

Q: Why is the IRF8707GPBF marked as Obsolete?

A: Obsolete status indicates the manufacturer (Infineon) has discontinued production and no longer provides technical support or warranty. Substitute parts from active manufacturers ensure continued availability and manufacturer backing for new production requirements.

Q: Which substitute part has the lowest on-state resistance?

A: DMN3016LSS-13 and RXH125N03TB1 both offer 12mOhm Rds On at 10V, compared to the original 11.9mOhm. FDS6690A provides 12.5mOhm. These differences are negligible for most applications and fall within normal manufacturing tolerances.

Q: Are there any gate charge differences I should consider?

A: Yes. The IRF8707GPBF has 9.3nC gate charge at 4.5V. Substitute parts range from 4.6nC (STS10N3LH5) to 26nC (FDS8878). Lower gate charge enables faster switching; higher gate charge may require stronger gate drive circuits. Select based on your gate driver capability and switching frequency requirements.

Q: What is the significance of Product Status "Not For New Designs"?

A: This status indicates the manufacturer continues production but recommends against using the part in new circuit designs. These parts remain suitable for field replacements and legacy system support where the original part is unavailable. For new production, select parts with Active status.

Q: Do all substitute parts support the full -55°C to 150°C operating range?

A: All listed parts support -55°C to 150°C junction temperature range except RXH125N03TB1, which specifies 150°C maximum without lower temperature specification in provided data. Verify RXH125N03TB1 lower temperature limit with Rohm Semiconductor if operation below 0°C is required.

Q: Which substitute offers the best thermal performance?

A: DMN3016LSS-13 provides the lowest power dissipation at 1.5W (Ta), reducing thermal load on the PCB and heat sink. This part is optimal for thermally constrained designs or high-frequency switching applications where heat generation must be minimized.
