DMN5L06T-7 Equivalent & Substitute Parts

Part Overview

The DMN5L06T-7 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 50V drain-to-source voltage with 280mA continuous drain current in a surface mount SOT-523 package. This device is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. The compact SOT-523 form factor and low-power characteristics make this component suitable for signal switching and low-current control applications in portable and space-constrained designs.

Substitute Part Grouping Explanation

Substitution of the DMN5L06T-7 is determined by electrical and mechanical compatibility within the following parameter constraints:

Electrical Compatibility Criteria:

• FET Type: N-Channel topology required
• Drain to Source Voltage (Vdss): Substitute must equal or exceed 50V rating
• Continuous Drain Current (Id): Substitute must support minimum 280mA at 25°C
• Gate-Source Voltage (Vgs): Operating range must accommodate ±20V maximum
• Operating Temperature: Must span -55°C to 150°C minimum
• Power Dissipation: Substitute must handle thermal requirements of target application

Mechanical Compatibility Criteria:

• Mounting Type: Surface mount only
• Package Form Factor: SOT-523 or compatible footprint alternatives
• RoHS and REACH Compliance: ROHS3 Compliant and REACH Unaffected status required

The substitute part 2N7002PW,115 meets these criteria with higher voltage rating (60V), increased current capability (310mA), and improved power dissipation (260mW), while maintaining N-Channel MOSFET topology and surface mount configuration.

Parameter Comparison

Engineering Selection Recommendations

The 2N7002PW,115 serves as a direct functional substitute for the obsolete DMN5L06T-7 based on the following engineering criteria:

Electrical Performance: The substitute exceeds the original part specifications across all critical parameters. The 60V Vdss rating provides 20% voltage margin above the 50V requirement, while the 310mA continuous drain current exceeds the 280mA specification by 10.7%. Power dissipation capability increases from 150mW to 260mW, providing additional thermal headroom for circuit operation.

Compliance Status: Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in production environments. The substitute carries AEC-Q100 automotive qualification, indicating enhanced reliability screening and process control.

Package Consideration: The substitute transitions from SOT-523 to SOT-323 (SC-70) packaging. While these are distinct physical packages, both are surface mount configurations with compatible lead spacing for standard PCB assembly processes. PCB layout modification is required to accommodate the different footprint geometry.

Product Lifecycle: The original part is classified as obsolete, while the substitute is designated "Not For New Designs." This status indicates the substitute remains available for legacy system support and maintenance applications, with extended inventory availability (423,300 pieces in stock versus 924 pieces for the original).

Frequently Asked Questions (FAQ)

Q: Can the 2N7002PW,115 directly replace the DMN5L06T-7 without circuit modification?

A: Electrical substitution is valid without circuit redesign. Both devices are N-Channel MOSFETs with compatible gate-source voltage ranges (±20V) and operating temperature spans (-55°C to 150°C). The substitute's higher voltage and current ratings provide performance margin. However, PCB layout modification is necessary due to package change from SOT-523 to SOT-323.

Q: What is the significance of the package change from SOT-523 to SOT-323?

A: SOT-523 and SOT-323 are distinct surface mount packages with different physical dimensions and lead configurations. SOT-323 (SC-70) is a more common industry standard with wider availability. PCB footprint redesign is required, but both packages are compatible with standard reflow soldering processes. Verify PCB layout space availability before implementation.

Q: Are there thermal considerations when substituting to the 2N7002PW,115?

A: The substitute provides 73% greater power dissipation capability (260mW versus 150mW). This represents improved thermal performance and allows operation in higher-power applications. Existing thermal management provisions designed for the original part remain adequate for the substitute.

Q: Does the higher Vgs(th) of the substitute affect gate drive requirements?

A: The substitute exhibits Vgs(th) of 2.4V compared to 1.2V for the original part. This indicates a higher threshold voltage for gate conduction. Verify that existing gate drive circuitry provides sufficient voltage margin above the 2.4V threshold to ensure reliable switching performance at the intended operating point.

Q: What inventory considerations apply to this substitution?

A: The original DMN5L06T-7 is obsolete with limited stock (924 pieces). The substitute 2N7002PW,115 is widely available (423,300 pieces in stock) through multiple distribution channels, ensuring long-term supply continuity for production and maintenance applications.
