Engineering Selection Recommendations

B82462G4153M000 (EPCOS - TDK Electronics)

This part is the primary recommended substitute. It exceeds the original specification with 1.25 A current rating versus 1.2 A, and provides superior DC resistance at 97 mOhm maximum compared to 120 mOhm. The extended operating temperature range (-55°C to 150°C) provides additional thermal margin. The part carries AEC-Q200 automotive qualification, indicating enhanced reliability screening. Product status is Active, supporting long-term availability. The 6.30 mm × 6.30 mm footprint requires PCB layout verification for clearance compatibility.

SLF6028T-150M1R0-PF (TDK Corporation)

This substitute offers the highest current rating at 1.4 A and the lowest DC resistance at 89.4 mOhm maximum, delivering superior thermal performance and lower power dissipation. However, the product status is Not For New Designs, limiting its suitability for new development programs. The 3.00 mm maximum height exceeds the original 2.20 mm, requiring clearance verification in space-constrained applications. This part is appropriate for legacy system maintenance or where existing inventory supports continued use.

SLF6025T-150MR88-PF (TDK Corporation)

This substitute meets the minimum current requirement at 1.1 A with 102 mOhm maximum DC resistance. The product status is Not For New Designs, indicating this part is in end-of-life phase. The operating temperature range (-40°C to 105°C) is narrower than the original, providing reduced thermal margin at the upper temperature limit. This part is suitable only for replacement applications where design changes are not feasible.

Frequently Asked Questions (FAQ)

Q: Can B82462G4153M000 be used as a direct replacement for ASPI-0615FS-150M-T2?

A: B82462G4153M000 is electrically compatible and meets all substitution criteria. The 6.30 mm × 6.30 mm footprint is slightly larger than the original 6.00 mm × 6.00 mm, requiring PCB layout verification to confirm adequate clearance around the component location. Height increase from 2.20 mm to 3.00 mm must also be verified against board-level clearance constraints.

Q: Why are SLF6025T-150MR88-PF and SLF6028T-150M1R0-PF marked as Not For New Designs?

A: These TDK parts are in end-of-life status, indicating the manufacturer is discontinuing production. While electrically and mechanically compatible, they are not recommended for new product development due to uncertain long-term availability. These parts are appropriate only for sustaining production of existing designs or field replacements where design changes are impractical.

Q: What is the impact of lower DC resistance in substitute parts?

A: Lower DC resistance reduces power dissipation and heat generation during operation. B82462G4153M000 at 97 mOhm and SLF6028T-150M1R0-PF at 89.4 mOhm both provide improved thermal performance compared to the original 120 mOhm specification. This is beneficial in applications with continuous or high-duty-cycle current operation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts carry ROHS3 compliance certification, matching the original ASPI-0615FS-150M-T2. All parts are also REACH Unaffected and carry EAR99 export classification.

Q: What is the significance of the AEC-Q200 rating on B82462G4153M000?

A: AEC-Q200 is an automotive industry qualification standard indicating the part has undergone enhanced reliability testing and screening. This certification provides additional confidence in component quality and long-term performance stability, particularly valuable for mission-critical or automotive applications.

Q: Can height differences affect PCB assembly?

A: Yes. The original part has a maximum seated height of 2.20 mm. B82462G4153M000 and SLF6028T-150M1R0-PF both reach 3.00 mm maximum height, while SLF6025T-150MR88-PF reaches 2.70 mm. These differences must be verified against PCB clearance requirements, conformal coating processes, and enclosure constraints before implementation.
