Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC5400YWM are selected based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Number of Outputs: 16 channels (all substitutes maintain this specification)
• Device Type: Linear LED Driver with internal switching capability
• RoHS3 Compliance: All substitutes meet this regulatory requirement
• Surface Mount Technology: All alternatives use surface mount packaging

Secondary Compatibility Factors:

• Supply Voltage Overlap: Substitutes must operate within or encompass the 4.75V to 5.5V range
• Current Output Capability: Per-channel current ratings determine application suitability
• Operating Temperature Range: Minimum -40°C lower bound maintained across all options
• Package Compatibility: Physical dimensions and pin counts affect PCB integration

The four substitute parts listed (MAX7304ETG+T, TLC5928DBQR, TLC59401RHBR, TLC5944PWPR) represent active production alternatives from Analog Devices Inc./Maxim Integrated and Texas Instruments that maintain the 16-output architecture while offering variations in current capacity, voltage range, and package form factors.

Parameter Comparison

Engineering Selection Recommendations

MAX7304ETG+T (Analog Devices Inc./Maxim Integrated)

This substitute is suitable for applications where the MIC5400YWM supply voltage range of 4.75V to 5.5V can be adapted to the MAX7304ETG+T operating range of 1.62V to 3.6V. The lower per-channel current rating of 20mA versus the original 30mA requires verification that LED load requirements are satisfied. The 24-WFQFN package represents a smaller footprint than the original 28-SOIC. This device maintains active production status and carries superior moisture sensitivity rating (MSL 1, Unlimited versus MSL 2, 1 Year). All RoHS3 and REACH compliance requirements are met.

TLC5928DBQR (Texas Instruments)

This substitute maintains full supply voltage compatibility (3V to 5.5V encompasses the original 4.75V to 5.5V range) and provides 35mA per-channel output, exceeding the original 30mA specification. The shift register topology differs from the standard linear architecture of the MIC5400YWM. The 24-SSOP package is smaller than the original 28-SOIC. Active production status and full RoHS3 compliance are confirmed. Operating temperature maximum is reduced to 85°C from the original 125°C.

TLC59401RHBR (Texas Instruments)

This substitute offers the highest per-channel current capability at 120mA, suitable for high-brightness LED applications. Supply voltage range (3V to 5.5V) encompasses the original specification. The shift register topology and 32-VFQFN package represent significant architectural and physical changes from the MIC5400YWM. Active production status and RoHS3 compliance are confirmed. Operating temperature maximum is 85°C. This device is specified for backlight and signage applications.

TLC5944PWPR (Texas Instruments)

This substitute provides 60mA per-channel output with full supply voltage compatibility (3V to 5.5V). The shift register topology and 28-PowerTSSOP package maintain similar pin count to the original 28-SOIC. Active production status and RoHS3 compliance are confirmed. Operating temperature maximum is 85°C. This device is specified for signage applications and provides output voltage range of 3V to 15V.

Frequently Asked Questions (FAQ)

Q: Why is the MIC5400YWM classified as obsolete?

A: The MIC5400YWM has reached end-of-life status with Microchip Technology. While inventory remains available (3894 pcs), no new production is scheduled. Substitute parts ensure long-term design support and production continuity.

Q: Can the MAX7304ETG+T directly replace the MIC5400YWM in existing designs?

A: Direct replacement requires circuit redesign. The MAX7304ETG+T operates at 1.62V to 3.6V supply voltage, which does not overlap with the MIC5400YWM 4.75V to 5.5V range. Additionally, the 20mA per-channel output is lower than the original 30mA specification. Package change from 28-SOIC to 24-WFQFN requires PCB layout modification.

Q: What is the primary difference between the MIC5400YWM and TLC5928DBQR?

A: The MIC5400YWM uses standard linear topology, while the TLC5928DBQR employs shift register architecture. The TLC5928DBQR provides higher per-channel current (35mA versus 30mA) and operates across a compatible voltage range (3V to 5.5V). Package changes from 28-SOIC to 24-SSOP. Both maintain 16 output channels and RoHS3 compliance.

Q: Which substitute offers the highest current output per channel?

A: The TLC59401RHBR provides 120mA per-channel output, the highest among all listed substitutes. This device is suitable for high-brightness LED applications and is specified for backlight and signage use. The 32-VFQFN package is larger than the original 28-SOIC.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts (MAX7304ETG+T, TLC5928DBQR, TLC59401RHBR, TLC5944PWPR) carry ROHS3 Compliant certification. All are also REACH Unaffected and classified under ECCN EAR99.

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

A: MSL ratings indicate moisture sensitivity during storage and handling. The MIC5400YWM carries MSL 2 (1 Year), requiring controlled storage conditions. The MAX7304ETG+T offers superior MSL 1 (Unlimited), allowing indefinite storage without special moisture control. Other substitutes maintain MSL 2 (1 Year) rating.

Q: Can the TLC5944PWPR operate at the original MIC5400YWM supply voltage?

A: Yes. The TLC5944PWPR supply voltage range of 3V to 5.5V fully encompasses the MIC5400YWM specification of 4.75V to 5.5V. The device provides 60mA per-channel output and maintains the 28-pin package count, though the package type changes from 28-SOIC to 28-PowerTSSOP.

Q: What is the operating temperature difference between the MIC5400YWM and substitute parts?

A: The MIC5400YWM operates to 125°C (TJ), while all four substitute parts operate to maximum 85°C (TA). This 40°C reduction in maximum operating temperature must be evaluated for high-temperature applications. All substitutes maintain the -40°C minimum temperature specification.

Q: Do all substitutes maintain the 16-output channel configuration?

A: Yes. All four substitute parts maintain exactly 16 output channels, matching the MIC5400YWM architecture. This parameter is consistent across all alternatives and represents a primary selection criterion for functional equivalence.
