Key Parameters

Substitute Part Grouping Explanation

Substitution of the A6282EESTR-T is determined by the following critical parameters:

• 16 output channels with shift register topology
• Linear driver type with internal switching capability
• Supply voltage range: 3V to 5.5V
• Per-channel output current capability (50mA nominal)
• Surface mount packaging compatibility
• Operating temperature range: -40°C to 85°C
• ROHS3 compliance and EAR99 classification

Substitute parts are grouped based on matching or exceeding these core electrical specifications while maintaining functional equivalence in shift register LED driver applications. Package form factor variations are acceptable where pin-compatible alternatives exist.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status with ROHS3 compliance and EAR99 classification, ensuring regulatory continuity with the obsolete A6282EESTR-T.

Direct Current-Matched Substitutes: TLC5929PWP provides the closest electrical match with 50mA per-channel output current, matching the A6282EESTR-T specification exactly. This part is available in 24-HTSSOP packaging and maintains the same operating temperature range.

Higher Current Capability Substitutes: CAT4016HV6-GT2, MAX6969AUG+T, MAX6969AWG+, TLC5927IDWR, TLC5927IPWPR, TLC5927QPWPRQ1, and TLC5945PWPR offer increased per-channel current ratings (55mA to 120mA), providing design margin for applications requiring higher LED drive capability. These parts are suitable where output current headroom is beneficial.

Lower Current Substitutes: TLC59281RGET provides 35mA per-channel output, suitable for applications where the A6282EESTR-T's 50mA capability exceeds requirements.

Marginal Current Substitutes: TLC59482DBQR operates at 45mA per-channel, providing near-equivalent performance with minimal current reduction.

Automotive-Grade Option: TLC5927QPWPRQ1 includes AEC-Q100 qualification and automotive-grade certification, appropriate for automotive lighting applications requiring enhanced reliability standards.

Extended Temperature Range: MAX6969AUG+T and MAX6969AWG+ support -40°C to 125°C operating range, exceeding the A6282EESTR-T specification by 40°C, suitable for high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the A6282EESTR-T with any of these substitute parts?

A: Direct replacement depends on package compatibility and current requirements. TLC5929PWP offers the closest electrical match in a different package form. Verify PCB layout compatibility with the target package before implementation.

Q: What is the primary reason for substitution?

A: The A6282EESTR-T is classified as obsolete. All listed substitutes are active products with current manufacturing availability and long-term supply assurance.

Q: Which substitute provides the best current compatibility?

A: TLC5929PWP matches the A6282EESTR-T at 50mA per-channel output current. For applications requiring higher current capability, CAT4016HV6-GT2 and TLC5945PWPR provide 80mA per-channel with maintained frequency specifications.

Q: Are there package differences between the main part and substitutes?

A: Yes. The A6282EESTR-T uses 24-WFQFN packaging. Substitutes employ various packages including 24-TQFN, 24-TSSOP, 24-SOIC, 24-HTSSOP, 24-VQFN, and 28-HTSSOP. Verify pin compatibility and PCB footprint requirements for your application.

Q: Do all substitutes meet the same compliance standards?

A: All listed substitutes are ROHS3 compliant and EAR99 classified, matching the A6282EESTR-T regulatory profile. MAX6969AUG+T and MAX6969AWG+ provide extended operating temperature range to 125°C. TLC5927QPWPRQ1 includes automotive-grade AEC-Q100 qualification.

Q: What frequency considerations apply to substitution?

A: The A6282EESTR-T operates at 30MHz. Most substitutes maintain this specification. CAT4016HV6-GT2 operates at 25MHz, and TLC5929PWP at 20MHz. These variations are acceptable for typical LED driver applications where frequency is not a critical design constraint.

Q: Which substitute offers the best supply availability?

A: CAT4016HV6-GT2 shows the highest inventory level at 289,100 pieces. MAX6969AWG+ provides 215,447 pieces. Both ensure long-term supply continuity for production requirements.
