Substitute Part Grouping Explanation
Substitution compatibility for the TLE42402MHTSA1 is determined by the following critical parameters:
- Linear topology with internal switching capability
- Single output configuration
- Supply voltage range compatibility (minimum 3V, maximum 45V)
- Output current capability (58mA nominal)
- Surface mount packaging with compatible pinout
- Operating temperature range (-40°C to 150°C)
The substitute parts listed below meet these core functional requirements. However, substitution feasibility depends on specific application constraints including package footprint compatibility, exact pinout matching, and thermal performance requirements. Parts are grouped by their alignment with the original specifications.

Engineering Selection Recommendations
AL5809-50S1-7 (Diodes Incorporated): Active product status with 50mA output current closely matching the original 58mA specification. Supply voltage range extends to 60V maximum. ROHS3 compliant. MSL-3 rating requires controlled storage conditions. SOD-123 package differs from original footprint.
AL8400SE-7 (Diodes Incorporated): Active product with no internal switch, limiting direct functional equivalence. Supply voltage maximum of 18V falls below the original 45V specification. MSL-1 rating provides unlimited storage. SOT-353 package incompatible with original footprint.
BD8374HFP-MTR (Rohm Semiconductor): Active product with 500mA output current exceeding original specification. Supply voltage range of 4.5V to 42V overlaps original range. Automotive-grade with AEC-Q100 qualification. Operating temperature limited to -40°C to 125°C. HRP-7 package incompatible with original footprint.
LP5522TMX/NOPB (Texas Instruments): Active product with 20mA output current significantly below original 58mA specification. Supply voltage maximum of 5.5V restricts high-voltage applications. Operating temperature range of -30°C to 85°C narrower than original. 6-DSBGA package incompatible with original footprint.

Frequently Asked Questions (FAQ)
Q: Can AL5809-50S1-7 directly replace TLE42402MHTSA1?
A: Functional compatibility exists for linear LED driver applications requiring 50mA output current within 2.5V to 60V supply range. Package footprint differs (SOD-123 vs. 6-SMD Gull Wing), requiring PCB redesign. MSL-3 moisture sensitivity requires controlled storage versus MSL-1 unlimited storage of original.
Q: Why does BD8374HFP-MTR have higher current rating than the original?
A: BD8374HFP-MTR is rated for 500mA output current, significantly exceeding the original 58mA specification. This part suits applications requiring higher LED drive current. Package incompatibility and automotive qualification may introduce design constraints.
Q: Which substitute maintains the widest supply voltage range?
A: AL5809-50S1-7 supports 2.5V to 60V, extending beyond the original 3V to 45V range. This provides greater flexibility for applications with variable supply voltages.
Q: Are there active product alternatives to the obsolete TLE42402MHTSA1?
A: Five active product alternatives exist: AL5809-50S1-7, AL8400SE-7, BD8374HFP-MTR, LP5522TMX/NOPB, and NCR402UH. All require evaluation against specific application requirements including output current, supply voltage, operating temperature, and package compatibility.
Q: What is the significance of MSL rating differences?
A: MSL-1 (unlimited storage) parts like AL8400SE-7, BD8374HFP-MTR, LP5522TMX/NOPB, NCR402UH, and TSCR402CX6 RFG require no moisture control during storage. AL5809-50S1-7 with MSL-3 requires controlled storage at specified humidity and temperature for 168 hours maximum before reflow soldering.
Q: Which substitute offers automotive qualification?
A: BD8374HFP-MTR carries AEC-Q100 qualification. NCR402UH and TSCR402CX6 RFG carry AEC-Q101 qualification. These certifications suit automotive and high-reliability applications.
Q: How do operating temperature ranges compare?
A: Original part operates -40°C to 150°C (TJ). NCR402UH and TSCR402CX6 RFG extend to -55°C minimum. LP5522TMX/NOPB is limited to -30°C to 85°C, the narrowest range among alternatives.
