Engineering Selection Recommendations

DAN202KT146 (Rohm Semiconductor)

The DAN202KT146 is a parametric equivalent to the DAN202KFHT146, differing only in packaging format. The main part is supplied in Tape & Reel (TR) format, while the DAN202KT146 is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts are manufactured by Rohm Semiconductor and carry identical electrical specifications, package dimensions, and compliance certifications. Selection between these two part numbers is determined by procurement and assembly requirements rather than technical performance. The DAN202KT146 offers significantly higher inventory availability (205,245 pieces versus 3,283 pieces).

1SS184,LF (Toshiba Semiconductor and Storage)

The 1SS184,LF is a parametric equivalent manufactured by Toshiba Semiconductor and Storage. All critical electrical parameters—reverse voltage, forward current, forward voltage, and reverse recovery time—are identical to the DAN202KFHT146. The package designation is TO-236-3, SC-59, SOT-23-3 with Surface Mount mounting type. Both parts are ROHS3 Compliant and carry MSL 1 (Unlimited) rating.

The 1SS184,LF exhibits higher reverse leakage current (500 nA @ 80 V versus 100 nA @ 70 V) and a lower maximum junction temperature (125°C versus 150°C). These differences do not affect substitution eligibility for applications within the specified electrical operating range. The 1SS184,LF is available in higher inventory (22,199 pieces).

All three part numbers are Active products with current manufacturing status and full compliance with RoHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can DAN202KT146 be used as a direct replacement for DAN202KFHT146?

A: Yes. The DAN202KT146 is a direct parametric equivalent. Both parts are manufactured by Rohm Semiconductor with identical electrical specifications, package dimensions (TO-236-3, SC-59, SOT-23-3), and compliance certifications. The only difference is packaging format: DAN202KFHT146 is supplied in Tape & Reel format, while DAN202KT146 is supplied in Cut Tape & Digi-Reel® format. Selection depends on assembly line requirements and inventory management.

Q: Can 1SS184,LF be used as a direct replacement for DAN202KFHT146?

A: Yes. The 1SS184,LF meets all critical electrical and mechanical substitution criteria. Reverse voltage (80 V), forward current (100 mA), forward voltage (1.2 V @ 100 mA), and reverse recovery time (4 ns) are identical. Package type (TO-236-3, SC-59, SOT-23-3) and mounting method (Surface Mount) are identical. Both parts are ROHS3 Compliant with MSL 1 (Unlimited). The 1SS184,LF is manufactured by Toshiba Semiconductor and Storage rather than Rohm Semiconductor.

Q: What are the differences between the substitute parts?

A: DAN202KT146 and DAN202KFHT146 are identical except for packaging format. The 1SS184,LF differs in two secondary parameters: reverse leakage current (500 nA @ 80 V versus 100 nA @ 70 V) and maximum junction temperature (125°C versus 150°C). These differences do not affect substitution for applications operating within the specified electrical range.

Q: Are all three parts suitable for automotive applications?

A: The DAN202KFHT146 and DAN202KT146 carry AEC-Q101 automotive qualification. The 1SS184,LF does not list AEC-Q101 qualification in the provided specifications. For applications requiring automotive-grade certification, DAN202KFHT146 or DAN202KT146 are the appropriate selections.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) format supplies components on continuous tape wound on a reel, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® format supplies components on cut tape segments, suitable for lower-volume assembly or manual handling. Both formats contain identical components; packaging selection is determined by assembly equipment and production volume requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, all three parts use identical Surface Mount package dimensions (TO-236-3, SC-59, SOT-23-3) and can be placed using the same PCB footprint and assembly equipment settings. Packaging format (Tape & Reel versus Cut Tape) affects supply chain logistics but not PCB assembly compatibility.

Q: Which part should be selected for new designs?

A: For new designs requiring automotive qualification, select DAN202KFHT146 or DAN202KT146 (both Rohm Semiconductor with AEC-Q101 certification). For applications without automotive requirements, all three parts are suitable. Selection between DAN202KFHT146 and DAN202KT146 depends on packaging format preference and inventory availability. The 1SS184,LF offers an alternative source from Toshiba Semiconductor and Storage.
