Frequently Asked Questions (FAQ)

Q: Can the AOB262L be directly replaced with any of these substitute parts?

A: Direct replacement is possible only with parts that maintain identical electrical specifications and package compatibility. All listed substitutes share the same TO-263 (D2PAK) surface mount package and 60V Vdss rating (except NP100N055PUK-E1-AY at 55V). However, continuous drain current ratings vary. For applications requiring the full 140A rating, BUK963R3-60E,118 and FDB029N06 are the closest matches at 120A. For lower current applications, other substitutes are suitable.

Q: What is the significance of the Rds On parameter in selecting a substitute?

A: Rds On (on-state resistance) directly affects power dissipation and thermal performance. The AOB262L has Rds On of 2.8 mOhm at 20A, 10V. Substitutes with lower Rds On values (such as IPB026N06NATMA1 at 2.6 mOhm) provide improved efficiency and reduced heat generation. Substitutes with higher Rds On values increase power dissipation and may require thermal management adjustments.

Q: Why is the NP100N055PUK-E1-AY listed as a substitute if its Vdss is 55V instead of 60V?

A: The NP100N055PUK-E1-AY is included because it meets all other critical parameters and is electrically compatible for applications where the maximum voltage stress does not exceed 55V. For applications requiring the full 60V rating, this part is not suitable.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive qualification standard that certifies the component has undergone rigorous testing for reliability, performance, and quality in automotive applications. Parts with AEC-Q101 qualification (BUK963R3-60E,118, DMTH6004SCTBQ-13, and IPB90N06S404ATMA2) are suitable for automotive and high-reliability applications.

Q: Are all substitute parts ROHS3 compliant?

A: Most active-status substitutes are ROHS3 compliant, including BUK963R3-60E,118, DMTH6004SCTBQ-13, IPB026N06NATMA1, NP100N055PUK-E1-AY, PSMN004-60B,118, PSMN3R0-60BS,118, and IPB90N06S404ATMA2. FDB029N06 and FDB035AN06A0 do not list explicit ROHS3 compliance in the provided specifications.

Q: What is the difference between Ta (ambient temperature) and Tc (case temperature) ratings?

A: Ta (ambient temperature) ratings assume the component operates in a 25°C ambient environment without active cooling. Tc (case temperature) ratings assume the component's case is maintained at 25°C through thermal management (heatsinking). The AOB262L is rated for 20A at Ta and 140A at Tc. Substitute parts with higher Tc ratings can deliver greater current when properly cooled.

Q: Which substitute offers the best thermal performance?

A: BUK963R3-60E,118 provides 293W power dissipation at case temperature, and PSMN3R0-60BS,118 provides 306W, both approaching the AOB262L's 333W rating. FDB035AN06A0 provides 310W power dissipation. These parts are suitable for high-power applications requiring maximum thermal capacity.

Q: Can I use a substitute with lower continuous drain current rating?

A: Yes, if your application does not require the full 140A rating. For example, DMTH6004SCTBQ-13, IPB026N06NATMA1, NP100N055PUK-E1-AY, and PSMN004-60B,118 are rated for 100A, 100A, 100A, and 75A respectively. Verify that your circuit's maximum current demand does not exceed the substitute's rating.

Q: What is the difference between the various package designations (TO-263, D2PAK, PG-TO263-3)?

A: TO-263, D2PAK, and PG-TO263-3 are equivalent package designations for the same physical form factor: a surface mount package with two leads plus a tab for thermal management. All listed substitutes use this package family and are mechanically interchangeable on standard PCB layouts.

Q: Why is IPB90N06S404ATMA2 marked as obsolete if it is listed as a substitute?

A: IPB90N06S404ATMA2 is included for reference and for applications where existing inventory exists. However, it is not recommended for new designs due to its obsolete status. Active-status alternatives such as BUK963R3-60E,118 or FDB029N06 are preferred for new product development.

Q: How do I determine which substitute is best for my application?

A: Selection depends on three factors: (1) required continuous drain current, (2) thermal management capability, and (3) compliance requirements. For high-current applications (>100A) with active cooling, BUK963R3-60E,118 or FDB029N06 are recommended. For automotive applications, AEC-Q101 qualified parts (BUK963R3-60E,118, DMTH6004SCTBQ-13) are required. For general industrial applications, PSMN3R0-60BS,118 or IPB026N06NATMA1 provide good performance with active status and ROHS3 compliance.
