Not Recommended for New Designs:

AOT410L (Alpha & Omega Semiconductor Inc.): Product status "Not For New Designs" disqualifies this part despite meeting electrical specifications.
AOB286L (Alpha & Omega Semiconductor Inc.): Vdss rating of 80V is below the 100V requirement; surface-mount TO-263 package incompatible with through-hole TO-220AB requirement.

Compliance Verification:

All recommended substitutes maintain RoHS3 compliance, REACH unaffected status, and EAR99 export classification consistent with the original PSMN5R6-100PS,127. Operating temperature range of -55°C to 175°C is supported across all recommended parts.

Frequently Asked Questions (FAQ)

Q1: Can I use a substitute part with lower continuous drain current rating than 100A?

A: Substitution with lower current ratings (75A, 80A, 120A) is application-dependent. If your circuit design requires exactly 100A continuous operation, only CSD19531KCS and AOT410L meet this specification. For applications with actual current draw below 75A, lower-rated parts such as FDP090N10, FDP100N10, FDP120N10, or FDP150N10 are functionally compatible. Verify actual circuit current requirements before selecting a lower-rated substitute.

Q2: What is the difference between Tc and Ta current ratings?

A: Tc (case temperature) represents continuous drain current at the device case temperature, typically 25°C under specified thermal conditions. Ta (ambient temperature) represents current at ambient temperature. Tc ratings are more conservative and represent actual device capability under thermal load. All substitutes listed use Tc ratings for consistency with the original PSMN5R6-100PS,127 specification.

Q3: Why is the TO-220AB package important for substitution?

A: The TO-220AB is a through-hole package with specific pin spacing (2.54mm), lead diameter, and thermal tab dimensions. Substitutes must use compatible through-hole TO-220 family packages (TO-220-3, TO-220AB) to ensure mechanical fit in existing PCB layouts and thermal interface compatibility with heatsinks. Surface-mount packages such as TO-263 (D2PAK) are not mechanically compatible and require PCB redesign.

Q4: Can I substitute the PSMN5R6-100PS,127 with AOB286L?

A: No. AOB286L has a maximum Vdss rating of 80V, which is below the 100V requirement of the original part. Additionally, AOB286L uses a surface-mount TO-263 (D2PAK) package, which is mechanically incompatible with the through-hole TO-220AB requirement. This part is not suitable for direct substitution.

Q5: What does "Not For New Designs" status mean for AOT410L?

A: "Not For New Designs" indicates that the manufacturer (Alpha & Omega Semiconductor Inc.) has designated this part for legacy support only and does not recommend its use in new product development. While AOT410L meets the electrical specifications (100V, 150A), its product status makes it unsuitable for new designs. CSD19531KCS or FDP047N10 are preferred alternatives with active product status.

Q6: How do I select between CSD19531KCS and FDP047N10?

A: Both parts are active and meet or exceed the 100V/100A specification. CSD19531KCS provides exact 100A rating with lower gate charge (38nC) and input capacitance (3870pF), resulting in faster switching and reduced gate drive power. FDP047N10 provides 120A rating with superior on-state resistance (4.7mOhm) and higher power dissipation capability (375W), offering greater thermal margin. Select CSD19531KCS for gate-drive-limited applications; select FDP047N10 for thermally demanding applications or when current margin is required.

Q7: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts listed carry RoHS3 compliance certification, consistent with the original PSMN5R6-100PS,127. Compliance status is verified in the provided specifications.

Q8: What is the significance of on-state resistance (Rds On) differences?

A: On-state resistance directly affects power dissipation and thermal performance. Lower Rds On values reduce I²R losses during conduction. The original part specifies 5.6mOhm @ 25A, 10V. Substitutes range from 4.7mOhm (FDP047N10) to 18mOhm (FDP3651U). Lower Rds On values reduce heat generation and improve efficiency; higher values increase thermal load. Select based on thermal budget and efficiency requirements of your application.

Q9: Can I use FDP150N10 if my application only requires 50A?

A: Yes. FDP150N10 is rated for 57A continuous drain current at Tc. If your actual circuit current requirement is 50A, this part is functionally compatible and provides adequate current margin. However, verify that the 15mOhm on-state resistance and 110W power dissipation are acceptable for your thermal design.

Q10: What package considerations apply when substituting from PSMN5R6-100PS,127?

A: The original part uses TO-220AB, a through-hole package. All recommended substitutes use TO-220-3 or TO-220AB packages, which are mechanically and thermally compatible. Pin spacing, lead diameter, and thermal tab dimensions are standardized across TO-220 family packages. No PCB layout modifications are required for through-hole TO-220 substitutions. Surface-mount alternatives (such as AOB286L in TO-263) require complete PCB redesign and are not direct substitutes.
