Substitute Part Grouping Explanation

Substitute parts for the AL5814QMP-13 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical or near-identical electrical specifications and package form factors. These parts are direct functional replacements with no design modifications required:

• Same supply voltage range (4.5V to 60V)
• Same output current (15mA)
• Same PWM dimming capability
• Same 8-MSOP package configuration
• Same operating temperature range (-40°C to 105°C)

Manufacturer Recommended Alternatives offer functional LED driver capability with variations in electrical parameters. These parts require design consideration due to differences in:

• Supply voltage range
• Output current capacity
• Package type
• Operating temperature specifications
• Internal switch configuration
• Product status (active vs. obsolete)

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (AL5814MP-13, AL5817MP-13)

AL5814MP-13 and AL5817MP-13 are parametric equivalents of the AL5814QMP-13, maintaining identical electrical specifications and package configuration. Both parts are manufactured by Diodes Incorporated and are currently active. These parts provide interchangeable functionality with no circuit modifications required. AL5814MP-13 offers 2700 units in stock, while AL5817MP-13 provides 7600 units, supporting high-volume production requirements.

Manufacturer Recommended Alternatives with Higher Output Current

APS13568ELJATR (Allegro MicroSystems) and IS31LT3172-GRLS4-TR (Lumissil Microsystems) offer increased output current capacity (150mA and 200mA respectively) compared to the 15mA specification of the AL5814QMP-13. These parts feature internal switches and are suitable for applications requiring higher LED drive current. However, APS13568ELJATR operates within a reduced supply voltage range (7V to 24V) and lower maximum operating temperature (85°C), while IS31LT3172-GRLS4-TR is currently obsolete.

Manufacturer Recommended Alternatives with Reduced Supply Voltage Range

BCR420UE6433HTMA1 (Infineon Technologies) is an automotive-grade device (AEC-Q101) with 65mA output current and maximum supply voltage of 40V. This part is suitable for automotive lighting applications but operates within a narrower voltage range than the AL5814QMP-13. TSCR421CX6 RFG (Taiwan Semiconductor Corporation) is an automotive-grade alternative with 11mA output current and maximum supply voltage of 4.5V, making it unsuitable for the full voltage range of the primary part. TSCR421CX6 RFG is currently obsolete.

Compliance and Certification Considerations

The AL5814QMP-13 carries AEC-Q100 automotive qualification. Among substitutes, only BCR420UE6433HTMA1 carries equivalent automotive qualification (AEC-Q101). For non-automotive applications, all active parts maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity levels vary; AL5814QMP-13, AL5814MP-13, AL5817MP-13, BCR420UE6433HTMA1, and TSCR421CX6 RFG maintain MSL-1 (unlimited) ratings, while APS13568ELJATR and IS31LT3172-GRLS4-TR carry MSL-3 (168 hours) ratings.

Frequently Asked Questions (FAQ)

Q: Can AL5814MP-13 and AL5817MP-13 be used as direct replacements for AL5814QMP-13?

A: Yes. Both parts maintain identical electrical specifications (4.5V to 60V supply, 15mA output, PWM dimming) and the same 8-MSOP package configuration. No circuit modifications are required for substitution.

Q: What are the key differences between the AL5814QMP-13 and higher-current alternatives like APS13568ELJATR?

A: APS13568ELJATR provides 150mA output current versus 15mA for the AL5814QMP-13, but operates within a reduced supply voltage range (7V to 24V maximum versus 60V maximum). The APS13568ELJATR also features an internal switch, whereas the AL5814QMP-13 does not. These differences require circuit design evaluation before substitution.

Q: Is BCR420UE6433HTMA1 suitable for automotive applications?

A: Yes. BCR420UE6433HTMA1 carries AEC-Q101 automotive qualification and is rated for automotive-grade operation. However, it operates within a maximum supply voltage of 40V compared to 60V for the AL5814QMP-13, and provides 65mA output current versus 15mA.

Q: Why are IS31LT3172-GRLS4-TR and TSCR421CX6 RFG marked as obsolete?

A: Both parts are listed with obsolete product status, indicating they are no longer in active production. While inventory may be available, long-term supply cannot be guaranteed. Active alternatives should be prioritized for new designs.

Q: What is the significance of MSL (Moisture Sensitivity Level) ratings in substitute selection?

A: MSL-1 (unlimited) rated parts like AL5814QMP-13 have no moisture exposure time restrictions during storage and handling. MSL-3 (168 hours) rated parts like APS13568ELJATR and IS31LT3172-GRLS4-TR require controlled moisture exposure and must be baked before reflow soldering if storage time exceeds 168 hours. This affects supply chain handling and manufacturing processes.

Q: Can TSCR421CX6 RFG replace AL5814QMP-13 in high-voltage applications?

A: No. TSCR421CX6 RFG has a maximum supply voltage of 4.5V, making it incompatible with the AL5814QMP-13 specification range of 4.5V to 60V. This part is suitable only for low-voltage applications below 4.5V.

Q: What package considerations apply when selecting substitutes?

A: The AL5814QMP-13 uses an 8-MSOP package. Direct equivalents AL5814MP-13 and AL5817MP-13 maintain this package. Alternative parts use different packages: APS13568ELJATR and IS31LT3172-GRLS4-TR use 8-SOIC, BCR420UE6433HTMA1 uses SC-74/SOT-457, and TSCR421CX6 RFG uses SOT-23-6. Package differences require PCB layout modifications and may affect thermal performance.
