Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMN5L06W-7 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Package: SOT-323 (SC-70) surface mount
• Drain to Source Voltage (Vdss): Equal to or greater than 50 V
• Continuous Drain Current (Id): Equal to or greater than 280 mA
• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute Parts Identified:

1. 2N7002PW,115 (Nexperia USA Inc.) — Vdss 60 V, Id 310 mA, SOT-323 package
2. BSS138WH6327XTSA1 (Infineon Technologies) — Vdss 60 V, Id 280 mA, SOT-323 package

Both substitute parts meet or exceed the electrical and mechanical requirements of the DMN5L06W-7 while maintaining identical package geometry and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The BSS138WH6327XTSA1 (Infineon Technologies) is the recommended substitute. This device carries Active product status, ensuring long-term availability and supply chain stability. The part is AEC-Q100 qualified and carries Automotive grade certification, providing enhanced reliability documentation. Power dissipation capability (500 mW) exceeds the original specification, offering design margin for thermal management.

For Existing Production: The 2N7002PW,115 (Nexperia USA Inc.) provides functional equivalence with higher drain current rating (310 mA vs. 280 mA). Although classified as Not For New Designs, this part maintains ROHS3 compliance and MSL 1 rating. Inventory availability (423,300 units) supports production continuity for legacy applications.

Compliance Verification: Both substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN/HTSUS classifications as the original DMN5L06W-7. Moisture sensitivity level remains at MSL 1 (Unlimited) for both alternatives, eliminating special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2N7002PW,115 directly replace the DMN5L06W-7 in existing PCB layouts?

A: Yes. Both devices use identical SOT-323 (SC-70) package geometry with matching pin configurations. No PCB layout modifications are required for mechanical or electrical interface compatibility.

Q: What is the significance of the higher Vdss rating (60 V) in the substitute parts?

A: The 60 V Vdss rating in both 2N7002PW,115 and BSS138WH6327XTSA1 exceeds the original 50 V specification. This provides additional voltage margin and does not create compatibility issues in circuits designed for 50 V operation. The device operates safely within the lower voltage envelope.

Q: Why does the BSS138WH6327XTSA1 have higher power dissipation (500 mW vs. 200 mW)?

A: The increased power dissipation rating reflects the thermal capability of the specific die and package implementation by Infineon. This does not indicate higher power consumption in the circuit; rather, it provides greater thermal headroom for the application. The actual power dissipation is determined by circuit operating conditions (Id, Vgs, switching frequency).

Q: Are there differences in gate threshold voltage (Vgs(th)) between the parts?

A: Yes. The DMN5L06W-7 specifies Vgs(th) of 1.2 V, while the 2N7002PW,115 specifies 2.4 V and the BSS138WH6327XTSA1 specifies 1.4 V. These variations are within normal MOSFET manufacturing tolerances. Circuit designs using gate drive voltages of 5 V or higher accommodate all three devices without modification.

Q: What is the product status implication for long-term supply?

A: The DMN5L06W-7 is Obsolete, indicating no further production. The 2N7002PW,115 is Not For New Designs, suggesting limited future availability. The BSS138WH6327XTSA1 carries Active status, ensuring continued manufacturing and supply chain support for new and ongoing production requirements.

Q: Do the substitute parts require different handling or storage procedures?

A: No. All three devices maintain MSL 1 (Unlimited) rating, eliminating moisture sensitivity concerns. Standard surface mount component handling procedures apply uniformly across all parts.

Q: How do the on-resistance (Rds On) specifications compare across the three devices?

A: Rds On values are specified at different test conditions. The DMN5L06W-7 specifies 3 Ohm @ 200 mA, 2.7 V; the 2N7002PW,115 specifies 1.6 Ohm @ 500 mA, 10 V; and the BSS138WH6327XTSA1 specifies 3.5 Ohm @ 200 mA, 10 V. Direct comparison requires normalization to identical test conditions. At equivalent gate drive voltages (10 V), the 2N7002PW,115 exhibits lower on-resistance, improving switching efficiency.
