FDS6692A N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The FDS6692A is an N-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with 9A continuous drain current at 25°C. This device is housed in an 8-SOIC surface mount package and belongs to the PowerTrench® series. The FDS6692A is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, production continuity, and component sourcing in applications where this MOSFET was previously specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FDS6692A are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Critical Matching Parameters:

• FET Type: N-Channel
• Drain to Source Voltage (Vdss): 30V minimum
• Continuous Drain Current (Id): Equal to or greater than 9A
• Package Type: 8-SOIC or equivalent 8-pin surface mount package
• Operating Temperature Range: -55°C to 150°C (TJ) minimum
• Technology: MOSFET (Metal Oxide)
• RoHS Compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Rds On (Max): Substitute parts may have equal or lower on-resistance values
• Gate Charge (Qg): Substitute parts may have equal or lower gate charge values
• Input Capacitance (Ciss): Substitute parts may have equal or lower input capacitance values
• Power Dissipation: Substitute parts may have equal or higher power dissipation ratings
• Moisture Sensitivity Level (MSL): Substitute parts may have equal or lower MSL ratings

The substitute parts listed below meet all critical matching parameters and fall within allowable variations for secondary electrical characteristics.

Engineering Selection Recommendations

BSO110N03MSGXUMA1 (Infineon Technologies OptiMOS™ Series)

The BSO110N03MSGXUMA1 is an active product with electrical specifications that exceed the FDS6692A requirements. It provides 10A continuous drain current versus 9A, with comparable on-resistance of 11 mOhm. Gate charge is reduced to 20 nC, and input capacitance is lower at 1500 pF, resulting in improved switching performance. The device is ROHS3 compliant and rated for the same operating temperature range. The primary consideration is the MSL rating of 3 (168 Hours) compared to the FDS6692A's MSL 1 (Unlimited), which may require adjusted moisture control procedures during storage and handling.

DMN3016LSS-13 (Diodes Incorporated)

The DMN3016LSS-13 is an active product offering 10.3A continuous drain current with 12 mOhm on-resistance. Gate charge is 25.1 nC and input capacitance is 1415 pF. This device maintains MSL 1 (Unlimited) rating, matching the FDS6692A's moisture sensitivity classification. Power dissipation is rated at 1.5W, and the device is ROHS3 compliant with identical operating temperature range. The 8-SO package is mechanically compatible with 8-SOIC footprints.

Both substitute parts are active products with current manufacturing support, ensuring long-term component availability and supply chain continuity compared to the obsolete FDS6692A.

Frequently Asked Questions (FAQ)

Q: Can the BSO110N03MSGXUMA1 be used as a direct replacement for the FDS6692A?

A: The BSO110N03MSGXUMA1 meets all critical electrical and mechanical substitution criteria. The primary difference is the MSL rating of 3 (168 Hours) versus the FDS6692A's MSL 1 (Unlimited). Applications requiring unlimited moisture exposure without baking cycles must account for this difference in handling procedures.

Q: What is the difference between the 8-SOIC, PG-DSO-8, and 8-SO packages?

A: All three packages are 8-pin surface mount configurations with 0.154" (3.90mm) width. The designations reflect different manufacturer naming conventions for functionally equivalent packages. PCB footprints designed for 8-SOIC are compatible with PG-DSO-8 and 8-SO devices.

Q: Are there performance differences between the substitute parts?

A: Both substitutes provide higher continuous drain current (10A and 10.3A respectively) compared to the FDS6692A's 9A rating. Gate charge and input capacitance are lower in both substitutes, resulting in faster switching characteristics. On-resistance values are comparable or slightly lower. These differences represent performance improvements rather than degradation.

Q: Which substitute part should be selected for new designs?

A: Both BSO110N03MSGXUMA1 and DMN3016LSS-13 are suitable for new designs. Selection depends on specific application requirements. The DMN3016LSS-13 maintains MSL 1 (Unlimited) rating, while the BSO110N03MSGXUMA1 offers slightly lower gate charge. Both are active products with established supply chains.

Q: Is PCB layout modification required when substituting these parts?

A: No PCB layout modification is required. All three devices use compatible 8-pin surface mount packages with identical pin spacing and footprint dimensions. Direct component substitution on existing PCBs is possible without layout changes.

Q: What is the significance of the "Active" product status for substitute parts?

A: Active product status indicates current manufacturing and ongoing supplier support. This ensures component availability for production runs, design revisions, and long-term field support. The FDS6692A's obsolete status makes active substitutes necessary for sustained product support.

Q: Are the substitute parts RoHS compliant?

A: Yes, both BSO110N03MSGXUMA1 and DMN3016LSS-13 are ROHS3 compliant, matching the FDS6692A's compliance status. Both are also REACH unaffected and classified as EAR99 for export control purposes.
