Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Closest Electrical Match):

MAX16839ASA+ and STCS05DR represent the closest functional equivalents to the AL5811MP-13. Both devices feature linear PWM dimming topology with internal switches, single outputs, and surface mount packages. MAX16839ASA+ operates within a 5V to 40V supply range with 100mA output current, matching the AL5811MP-13 current specification. STCS05DR extends output current capability to 500mA across a 4.5V to 40V supply range. Both parts maintain -40°C to 125°C operating temperature specifications and carry RoHS3 compliance with MSL-1 ratings, ensuring compatibility with existing supply chain and manufacturing processes.

Higher Current Capability Alternatives:

MIC4802YME and MAX16803ATE+ provide increased output current capacity (800mA and 350mA respectively) for applications requiring higher LED drive currents. MIC4802YME operates in a constrained 3V to 5.5V supply window, suitable for low-voltage systems. MAX16803ATE+ supports 6.5V to 40V operation and includes automotive-grade qualification. Both maintain PWM dimming and internal switch functionality.

Extended Temperature and Reliability Options:

TLD1125ELXUMA1 and TLE4241GMXUMA1 from Infineon provide extended operating temperature to 150°C (TJ) and automotive-grade qualification. TLD1125ELXUMA1 delivers 360mA output current across 5.5V to 40V supply range in a 14-LSSOP package. TLE4241GMXUMA1 provides 60mA output current across 4V to 45V supply range in an 8-SOIC package. Both carry MSL-3 ratings requiring controlled moisture exposure during storage and handling.

Package Consideration:

CL6N5-G operates as a through-hole TO-220-3 package alternative, suitable for applications requiring manual assembly or higher thermal dissipation through direct PCB mounting. This part extends supply voltage capability to 90V maximum and output current to 100mA, with operating temperature to 119°C (TJ).

All substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the AL5811MP-13 baseline.

Frequently Asked Questions (FAQ)

Q: Can MAX16839ASA+ directly replace AL5811MP-13 in existing PCB designs?

A: MAX16839ASA+ shares functional equivalence as a linear PWM LED driver with internal switch and single output. However, package differences exist: MAX16839ASA+ uses 8-SOIC-EP versus AL5811MP-13's 8-MSOP-EP. Pin-to-pin compatibility requires schematic verification. Both operate within overlapping supply ranges (5V to 40V for MAX16839ASA+ versus 4.6V to 60V for AL5811MP-13) and maintain identical -40°C to 125°C temperature specifications and MSL-1 ratings.

Q: What is the primary difference between STCS05DR and AL5811MP-13?

A: STCS05DR provides 500mA output current versus AL5811MP-13's 75mA, representing a 6.7x increase in drive capability. Both devices use linear PWM topology with internal switches and operate across overlapping supply ranges (4.5V to 40V for STCS05DR). STCS05DR extends maximum operating temperature to 150°C (TJ) compared to AL5811MP-13's 125°C (TA). Package differs: STCS05DR uses 8-SOIC without exposed pad, while AL5811MP-13 uses 8-MSOP-EP.

Q: Is MIC4802YME suitable for high-voltage applications?

A: No. MIC4802YME operates within a restricted 3V to 5.5V supply range, limiting use to low-voltage systems. This part is not suitable for applications requiring the AL5811MP-13's extended 4.6V to 60V supply capability. MIC4802YME is optimized for high-current, low-voltage LED driving at 800mA output.

Q: What does MSL-3 rating mean for TLD1125ELXUMA1 and TLE4241GMXUMA1?

A: MSL-3 (Moisture Sensitivity Level 3) indicates these parts require controlled moisture exposure during storage and handling, with a maximum floor life of 168 hours after bag opening at 30°C and 60% relative humidity. This contrasts with AL5811MP-13's MSL-1 rating (unlimited floor life). MSL-3 parts require baking before reflow soldering if floor life is exceeded, adding manufacturing process complexity.

Q: Can CL6N5-G replace AL5811MP-13 in surface mount applications?

A: No. CL6N5-G uses through-hole TO-220-3 packaging, incompatible with surface mount PCB designs. AL5811MP-13 is surface mount (8-MSOP-EP). CL6N5-G is suitable only for through-hole assembly designs or applications requiring manual component insertion and higher thermal dissipation through direct PCB contact.

Q: Which substitute part best matches AL5811MP-13 for automotive applications?

A: MAX16803ATE+ and TLD1125ELXUMA1 both carry automotive-grade qualification. MAX16803ATE+ provides 350mA output current in a 16-TQFN package across 6.5V to 40V supply range. TLD1125ELXUMA1 delivers 360mA output current in a 14-LSSOP package across 5.5V to 40V supply range. Both extend operating temperature to 125°C or 150°C (TJ) and maintain RoHS3 compliance. Selection depends on specific current and package requirements.

Q: What is the supply voltage overlap between AL5811MP-13 and its substitutes?

A: AL5811MP-13 operates 4.6V to 60V. Substitutes with overlapping ranges include: STCS05DR (4.5V to 40V), MAX16839ASA+ (5V to 40V), MAX16803ATE+ (6.5V to 40V), TLD1125ELXUMA1 (5.5V to 40V), TLE4241GMXUMA1 (4V to 45V), and CL6N5-G (6.5V to 90V). MIC4802YME (3V to 5.5V) covers only the low-voltage portion. No substitute matches the full 4.6V to 60V range; application voltage requirements determine suitable alternatives.
