Engineering Selection Recommendations
Direct Replacement: LP5522TM/NOPB is the parametric equivalent and serves as the primary substitute when identical electrical and mechanical specifications are required. Both parts maintain Active product status, ROHS3 compliance, and unlimited MSL rating.
Automotive Applications: BCR320UE6327HTSA1, NCR402UH, and NCR405UX carry AEC-Q101 automotive qualification. AL5809-100QP1-7 carries AEC-Q100 automotive qualification. These parts are suitable for automotive lighting and signage applications where qualification is mandated.
Extended Temperature Range: NCR402UH and NCR405UX support -55°C to 150°C operating temperature, exceeding the LP5522TMX/NOPB's -30°C to 85°C range. TLD1124ELXUMA1 supports -40°C to 150°C (TJ).
Higher Current Capacity: When LED load requirements exceed 20mA, NCR405UX (50mA), AL5809-100QP1-7 (100mA), APS13568ELJATR (150mA), BCR320UE6327HTSA1 (250mA), and TLD1124ELXUMA1 (360mA) provide proportionally increased output current while maintaining linear driver topology and internal switching.
Extended Supply Voltage: AL5809-100QP1-7 supports 2.5V to 60V supply with 60V output capability, accommodating high-voltage LED string applications. TLD1124ELXUMA1, NCR402UH, and NCR405UX support up to 40V supply voltage.
Moisture Sensitivity: APS13568ELJATR and TLD1124ELXUMA1 carry MSL-3 (168 Hours) rating, requiring controlled storage conditions. All other substitutes maintain MSL-1 (Unlimited) rating matching the original part.
Frequently Asked Questions (FAQ)
Q: Can NCR402UH directly replace LP5522TMX/NOPB in a 20mA LED application?
A: Yes. NCR402UH provides 20mA output current matching the original specification, operates across a compatible supply voltage range (up to 40V), and maintains linear driver topology with internal switching. The primary design consideration is package change from 6-DSBGA to 6-TSOP, requiring PCB layout modification. NCR402UH carries AEC-Q101 automotive qualification, providing additional reliability margin for non-automotive applications.
Q: What is the key difference between LP5522TMX/NOPB and AL5809-100QP1-7?
A: AL5809-100QP1-7 provides 100mA output current versus 20mA, supports extended supply voltage to 60V with 60V output capability, and carries AEC-Q100 automotive qualification. The package changes from 6-DSBGA to PowerDI™ 123. AL5809-100QP1-7 is suitable when higher current capacity or extended voltage range is required. Operating temperature extends to 125°C.
Q: Are APS13568ELJATR and TLD1124ELXUMA1 suitable for high-reliability applications?
A: Both parts are Active products with ROHS3 compliance. However, both carry MSL-3 (168 Hours) moisture sensitivity rating, requiring controlled storage and handling procedures. TLD1124ELXUMA1 provides higher current capacity (360mA) and extended operating temperature (-40°C to 150°C TJ). Neither part carries automotive qualification. For high-reliability applications requiring unlimited moisture sensitivity, select LP5522TM/NOPB, BCR320UE6327HTSA1, NCR402UH, or NCR405UX.
Q: What packaging considerations apply when substituting the LP5522TMX/NOPB?
A: The original part uses 6-DSBGA (6-pin ball grid array). Substitutes employ alternative surface mount packages: LP5522TM/NOPB (6-DSBGA), AL5809-100QP1-7 (PowerDI™ 123), APS13568ELJATR (8-SOIC-EP), BCR320UE6327HTSA1 (SC-74/SOT-457), NCR402UH (6-TSOP), NCR405UX (6-TSOP), and TLD1124ELXUMA1 (14-LSSOP-EP). Each package change requires PCB redesign, including trace routing, via placement, and thermal management considerations.
Q: Which substitute provides the closest electrical match to LP5522TMX/NOPB?
A: LP5522TM/NOPB is the parametric equivalent, matching all electrical specifications and differing only in packaging format. For applications requiring identical electrical performance with minimal design modification, LP5522TM/NOPB is the preferred substitute.
Q: Can NCR405UX replace LP5522TMX/NOPB in a 20mA application?
A: Yes. NCR405UX provides 50mA output current, exceeding the 20mA requirement. It operates across a compatible supply voltage range (up to 40V with 38V output), maintains linear driver topology with internal switching, and carries AEC-Q101 automotive qualification. The package changes from 6-DSBGA to 6-TSOP. The higher current capacity provides design margin for future load increases.
Q: What is the significance of the LITIX™ series designation for TLD1124ELXUMA1?
A: LITIX™ is Infineon's product series designation for LED driver ICs. TLD1124ELXUMA1 belongs to this series and provides 360mA output current with 14-LSSOP-EP packaging. The series designation indicates product family alignment but does not affect substitution eligibility, which is determined by electrical parameters and compliance certifications.
