Key Parameters

Substitute Part Grouping Explanation

Substitution of the FMM150-0075P is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 75V
• Configuration: Must maintain 2 N-Channel (Dual) topology
• Technology: Must be MOSFET (Metal Oxide) based
• Operating Temperature Range: Must support -55°C to 175°C (TJ)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole required
• Package Family: ISOPLUS i4-PAC™ or compatible pinout

Performance Parameters:

• Continuous Drain Current (Id): Rated capacity must support application requirements
• On-State Resistance (Rds On): Lower values indicate improved efficiency
• Gate Charge (Qg): Affects switching speed and driver requirements

The FMM150-0075X2F meets the core electrical and mechanical requirements for substitution, maintaining identical voltage rating, dual N-channel configuration, through-hole mounting, and compatible package family while offering active product status and current availability.

Engineering Selection Recommendations

FMM150-0075X2F as Primary Substitute:

The FMM150-0075X2F is the designated substitute for the obsolete FMM150-0075P. Both components share identical voltage ratings (75V Vdss), dual N-channel configuration, through-hole mounting, and compatible ISOPLUS package families. Both maintain the same operating temperature range (-55°C to 175°C TJ) and identical regulatory compliance status (REACH Unaffected, EAR99 classification, HTSUS 8541.29.0095).

The FMM150-0075X2F carries active product status, ensuring ongoing availability and manufacturing support. This component is currently in stock with 1,148 units available.

Key Differences:

The FMM150-0075X2F exhibits a reduced continuous drain current rating (120A versus 150A) and higher on-state resistance (5.8 mOhm versus 4.2 mOhm). These differences require evaluation against specific application current and thermal requirements. The substitute features lower gate charge (178nC versus 225nC), resulting in faster switching characteristics.

The FMM150-0075X2F is RoHS3 compliant, providing enhanced environmental compliance compared to the main part specification.

Regulatory and Compliance Alignment:

Both components maintain identical REACH and ECCN classifications, supporting seamless integration into existing supply chain and export compliance frameworks. Moisture sensitivity levels are equivalent (MSL 1, Unlimited), eliminating storage and handling requirement changes.

Frequently Asked Questions (FAQ)

Q: Can the FMM150-0075X2F directly replace the FMM150-0075P in existing designs?

A: The FMM150-0075X2F maintains electrical compatibility through identical voltage ratings, dual N-channel configuration, and operating temperature range. However, the reduced continuous drain current (120A versus 150A) and increased on-state resistance (5.8 mOhm versus 4.2 mOhm) require verification against application-specific current and thermal requirements. Mechanical compatibility is confirmed through compatible ISOPLUS through-hole packaging.

Q: What are the primary electrical differences between these components?

A: The FMM150-0075X2F provides lower gate charge (178nC versus 225nC), enabling faster switching response. The substitute exhibits higher on-state resistance and lower continuous drain current rating. Both maintain identical 75V voltage ratings and -55°C to 175°C operating temperature ranges.

Q: Are there packaging considerations for substitution?

A: Both components utilize through-hole mounting in ISOPLUS package families (i4-Pac™-5 and ISOPLUSi5-PAK™). Pin compatibility and board layout requirements must be verified against specific PCB designs, as package designations differ slightly.

Q: What is the inventory status of the substitute part?

A: The FMM150-0075X2F is actively manufactured and currently in stock with 1,148 units available. The original FMM150-0075P is obsolete with 924 units remaining in inventory.

Q: Are regulatory and compliance requirements identical?

A: Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8541.29.0095). The FMM150-0075X2F provides additional RoHS3 compliance certification. Moisture sensitivity levels are equivalent (MSL 1, Unlimited).

Q: How do gate charge differences affect circuit design?

A: The FMM150-0075X2F exhibits 21% lower gate charge (178nC versus 225nC). This reduces gate driver current requirements and enables faster switching transitions. Gate driver circuits designed for the original part will operate within acceptable parameters with the substitute, though switching speed will improve.
