Engineering Selection Recommendations

Primary Recommendation: BSP77E6433HUMA1 or BTS3118NHUMA1

Both parts are manufactured by Infineon Technologies and represent direct functional upgrades to the 98-0293. They provide 2.17A output current (2.9x the original specification), 70mOhm Rds On (5.3x improvement), and enhanced fault protection including Over Voltage detection. Both are ROHS3 compliant and carry active product status with substantial inventory availability (3400 and 12870 units respectively). The BTS3118NHUMA1 is supplied in Tape & Reel packaging, while BSP77E6433HUMA1 is available in Cut Tape & Digi-Reel format.

Secondary Recommendation: BTS3110NHUMA1

This Infineon part provides 1.4A output current (1.87x the original) with 150mOhm Rds On and full Over Voltage protection. It is suitable for applications where the 750mA specification is marginal but higher current capability is not required. ROHS3 compliant with 2000 units in stock.

Alternative Recommendation: BSP75GTA

The Diodes Incorporated BSP75GTA offers the highest voltage rating (60V) and includes Auto Restart functionality. With 1.6A output current and 550mOhm Rds On, it provides moderate performance improvement over the original part. This option is suitable for applications requiring higher voltage headroom. ROHS3 compliant with 41700 units available.

All substitute parts maintain identical operating temperature range, SOT-223 packaging, and Low Side N-Channel 1:1 topology. Selection should be based on specific current and voltage requirements of the target application, with preference for active, ROHS3-compliant alternatives.

Frequently Asked Questions (FAQ)

Q: Can the BSP77E6433HUMA1 directly replace the 98-0293 without circuit modifications?

A: Yes. Both parts share identical output configuration (Low Side N-Channel 1:1), operating temperature range (-40°C ~ 150°C), SOT-223 package, and On/Off interface. The BSP77E6433HUMA1 exceeds all electrical specifications of the 98-0293, including voltage rating (42V vs. 35V) and current capacity (2.17A vs. 750mA). Pin-compatible replacement is possible without design changes.

Q: What is the primary advantage of BTS3118NHUMA1 over BSP77E6433HUMA1?

A: Both parts are electrically identical (2.17A, 70mOhm Rds On, 42V rating). The distinction is packaging format: BTS3118NHUMA1 is supplied in Tape & Reel (TR) format with higher inventory (12870 units), while BSP77E6433HUMA1 is available in Cut Tape (CT) & Digi-Reel format (3400 units). Selection depends on procurement and assembly requirements.

Q: Why does BSP75GTA have higher Rds On (550mOhm) than other substitutes?

A: The BSP75GTA is manufactured by Diodes Incorporated using the INTELLIFET series technology, which differs from Infineon's HITFET architecture. Despite higher Rds On, it provides the highest voltage rating (60V) and includes Auto Restart protection. It is suitable for applications prioritizing voltage headroom over conduction efficiency.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (BSP77E6433HUMA1, BTS3110NHUMA1, BTS3118NHUMA1, BSP75GTA) are ROHS3 compliant. The original 98-0293 is RoHS non-compliant, making substitution necessary for applications requiring modern environmental compliance.

Q: What is the minimum current rating required for a valid substitute?

A: A valid substitute must support at least 750mA output current to maintain functional equivalence with the 98-0293. All identified substitutes exceed this threshold: BTS3110NHUMA1 (1.4A minimum), BSP75GTA (1.6A), and BSP77E6433HUMA1/BTS3118NHUMA1 (2.17A).

Q: Can BTS3110NHUMA1 be used in applications originally designed for 98-0293?

A: Yes. The BTS3110NHUMA1 provides 1.4A output current, which exceeds the original 750mA specification by 87%. It maintains all other critical parameters: Low Side N-Channel 1:1 configuration, -40°C ~ 150°C operating range, SOT-223 package, and enhanced Over Voltage protection. It is suitable for direct substitution.

Q: What is the significance of the 42V vs. 60V voltage rating difference?

A: The 98-0293 supports 35V maximum load voltage. Substitutes with 42V rating (Infineon HITFET series) provide 20% voltage margin improvement. The BSP75GTA with 60V rating provides 71% additional voltage headroom, making it suitable for applications with higher voltage transients or design margin requirements.
