AON6450L Equivalent & Substitute Parts

Part Overview

The AON6450L is an N-channel MOSFET manufactured by Alpha & Omega Semiconductor Inc., rated for 100V drain-to-source voltage with 52A continuous drain current at case temperature (Tc). This device is housed in a surface mount 8-DFN (5x6) package and is classified as Active product status. The AON6450L belongs to the SDMOS™ series and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory constraints, or when transitioning from legacy components to current production devices. The AON6450L has documented substitutes that maintain electrical and mechanical compatibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AON6450L is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Drain-to-Source Voltage (Vdss): 100V minimum
• Continuous Drain Current (Id) @ 25°C: 52A or greater at case temperature (Tc)
• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount
• Package compatibility: 8-DFN (5x6) or equivalent power package footprint

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The identified substitutes meet or exceed these parameters while maintaining functional equivalence in circuit applications. Substitution logic is based strictly on the ability to handle the same voltage and current specifications within the same or compatible package form factors.

Parameter Comparison

Engineering Selection Recommendations

AON6294 Substitution: The AON6294 is a direct electrical equivalent to the AON6450L, sharing identical 100V Vdss rating and 52A continuous drain current specification at case temperature. Both devices utilize the same 8-DFN (5x6) package footprint with 8-PowerSMD flat leads, enabling direct board-level substitution without layout modifications. Both parts are ROHS3 compliant with MSL 1 rating. However, the AON6294 carries a "Not For New Designs" product status, indicating it is a legacy component. This substitute is suitable for replacement applications, maintenance, or inventory supplementation where existing designs are already qualified to this part number.

PSMN012-100YS,115 Substitution: The PSMN012-100YS,115 manufactured by Nexperia USA Inc. meets the electrical requirements of the AON6450L with a 100V Vdss rating and 60A continuous drain current at case temperature, exceeding the 52A specification. This device is classified as Active product status, making it suitable for new designs. The PSMN012-100YS,115 is housed in an LFPAK56 (Power-SO8) package, which differs from the 8-DFN (5x6) footprint of the AON6450L. PCB layout modifications are required for this substitution. The part is ROHS3 compliant with MSL 1 rating and supports an extended operating temperature range of -55°C to 175°C compared to the AON6294's -55°C to 150°C range. This substitute is appropriate when package form factor changes are acceptable and higher current capability is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the AON6294 be used as a direct replacement for the AON6450L?

A: Yes, the AON6294 is electrically and mechanically compatible with the AON6450L. Both devices share identical 100V Vdss and 52A continuous drain current ratings, and both use the 8-DFN (5x6) package. Direct board-level substitution is possible without PCB layout changes. However, the AON6294 is designated "Not For New Designs," so it is suitable for replacement and maintenance applications only.

Q: What are the key differences between the AON6294 and PSMN012-100YS,115?

A: The primary differences are package form factor and product status. The AON6294 uses an 8-DFN (5x6) package identical to the AON6450L, while the PSMN012-100YS,115 uses an LFPAK56 (Power-SO8) package requiring PCB layout modifications. The PSMN012-100YS,115 offers higher continuous drain current (60A vs. 52A) and extended operating temperature range (-55°C to 175°C vs. -55°C to 150°C). The PSMN012-100YS,115 is Active product status, suitable for new designs.

Q: Does the PSMN012-100YS,115 require PCB layout changes?

A: Yes. The PSMN012-100YS,115 uses an LFPAK56 (Power-SO8) package, which has a different footprint than the AON6450L's 8-DFN (5x6) package. PCB layout modifications are necessary to accommodate this package change. The PSMN012-100YS,115 is not a pin-for-pin replacement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both the AON6294 and PSMN012-100YS,115 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the AON6450L's compliance profile.

Q: Which substitute should be selected for a new design?

A: The PSMN012-100YS,115 is the appropriate choice for new designs, as it carries Active product status. The AON6294, while electrically compatible, is designated "Not For New Designs" and should be reserved for replacement and maintenance applications.

Q: Can the PSMN012-100YS,115 handle higher current than the AON6450L?

A: Yes. The PSMN012-100YS,115 is rated for 60A continuous drain current at case temperature, compared to the AON6450L's 52A rating. This higher current capability makes it suitable for applications requiring increased current handling without exceeding the 100V voltage specification.
