Key Parameters

Substitute Part Grouping Explanation

Substitution of the AON7410L is determined by strict equivalence across the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain to Source Voltage (Vdss): Must equal or exceed 30V
• Package Type: Must be 8-DFN-EP (3x3) surface mount configuration
• On-Resistance (Rds On): Must not exceed 20mOhm @ 8A, 10V
• Gate Threshold Voltage (Vgs(th)): Must equal 2.5V @ 250µA
• Operating Temperature Range: Must support -55°C to 150°C
• Gate Voltage Rating (Vgs): Must support ±20V

Secondary Performance Parameters:

• Continuous Drain Current: Substitute devices may exceed the 8A (Ta) / 20A (Tc) ratings
• Power Dissipation: Substitute devices may exceed the 1.7W (Ta) / 20W (Tc) ratings
• Gate Charge and Input Capacitance: Must remain within specified limits

The AON7410 qualifies as a direct substitute based on identical voltage ratings, package configuration, on-resistance specification, and thermal operating range. Enhanced drain current ratings (9.5A Ta / 24A Tc) and power dissipation (3.1W Ta / 20W Tc) in the substitute provide improved performance margins without compromising circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

AON7410 as Primary Substitute:

The AON7410 is the direct equivalent for the obsolete AON7410L. Both devices share identical electrical specifications for voltage ratings, on-resistance, gate threshold voltage, and thermal operating range. The AON7410 provides enhanced continuous drain current ratings and power dissipation capability, delivering improved performance headroom in existing circuit designs without requiring layout or schematic modifications.

The AON7410 carries a product status of "Not For New Designs," indicating limited long-term availability. For new product development, evaluation of alternative N-Channel 30V MOSFETs in the 8-DFN-EP package with equivalent electrical parameters is recommended to ensure sustained component supply.

Compliance and Certifications:

Both the AON7410L and AON7410 maintain identical regulatory compliance profiles: REACH Unaffected status, EAR99 export classification, and MSL 1 moisture sensitivity rating. The AON7410 includes RoHS3 compliance certification, providing additional environmental regulatory alignment for applications subject to RoHS requirements.

Inventory and Availability:

The AON7410 maintains significantly higher inventory levels (250,100 pieces) compared to the obsolete AON7410L (18,199 pieces), supporting immediate procurement for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the AON7410 directly replace the AON7410L in existing circuit designs?

A: Yes. The AON7410 maintains identical electrical specifications for all critical parameters: 30V Vdss, 20mOhm Rds On @ 8A/10V, 2.5V Vgs(th), ±20V gate voltage rating, and -55°C to 150°C operating temperature range. The identical 8-DFN-EP (3x3) package permits direct substitution without PCB layout modifications. Enhanced drain current and power dissipation ratings in the AON7410 provide additional performance margin.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Drain to Source Voltage rating of 30V or higher, (2) On-Resistance not exceeding 20mOhm @ 8A, 10V, (3) Gate Threshold Voltage of 2.5V @ 250µA, (4) Gate voltage rating of ±20V, and (5) Operating temperature range supporting -55°C to 150°C. Package type must be 8-DFN-EP (3x3) surface mount.

Q: Are there differences in packaging or moisture sensitivity between the AON7410L and AON7410?

A: Both devices use identical 8-DFN-EP (3x3) surface mount packaging and carry MSL 1 (Unlimited) moisture sensitivity ratings. The AON7410 is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility in procurement quantities.

Q: What is the significance of the "Not For New Designs" status of the AON7410?

A: This status indicates the AON7410 has limited long-term availability and is not recommended for new product development. While suitable for replacement in existing designs, new designs should evaluate alternative N-Channel 30V MOSFETs in compatible packages to ensure sustained component supply throughout the product lifecycle.

Q: How do the power dissipation ratings differ between these devices?

A: The AON7410L is rated for 1.7W (Ta) and 20W (Tc) power dissipation. The AON7410 provides enhanced ratings of 3.1W (Ta) and 20W (Tc). The increased Ta rating provides additional thermal margin in ambient temperature-limited applications. Both devices maintain identical Tc ratings, indicating equivalent thermal performance under case temperature conditions.

Q: Are regulatory compliance certifications identical between the two devices?

A: Both devices maintain REACH Unaffected status and EAR99 export classification. The AON7410 includes RoHS3 compliance certification, which the AON7410L does not specify. For applications requiring RoHS compliance, the AON7410 provides explicit regulatory alignment.
