TLC5948APWPR LED Driver IC Equivalent & Substitute Parts

Part Overview

The TLC5948APWPR is a 16-output linear LED driver IC manufactured by Texas Instruments, designed for signage applications requiring precise current control across multiple LED channels. This active product operates across a 3V to 5.5V supply range with 60mA per-channel output capability in a 24-HTSSOP surface mount package. Substitute parts are identified when design requirements necessitate alternative packaging formats, enhanced thermal performance, extended temperature ranges, or different output current specifications while maintaining core functional compatibility as a 16-output linear shift register LED driver.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC5948APWPR is determined by the following core parameters: 16-output configuration, linear shift register topology, internal switching capability, 3V to 5.5V supply voltage range, surface mount technology, and ROHS3 compliance. Substitute parts must maintain these functional and regulatory requirements. Variations in the following parameters are permitted based on application requirements: per-channel output current (45mA to 100mA range), output voltage capability (5.5V to 26V), operating temperature range (-40°C to 85°C or extended to 125°C), package format (24-HTSSOP, 24-TSSOP, 24-QSOP, or 24-LSSOP), and moisture sensitivity level. All identified substitutes meet the core functional and compliance criteria while offering trade-offs in thermal performance, packaging density, or current delivery specifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the TLC5948APWPR. Selection among substitutes depends on specific application constraints:

MAX6969AUG+ offers the closest per-channel current specification (55mA versus 60mA) with superior moisture sensitivity rating (MSL 1, Unlimited) and extended operating temperature range to 125°C, suitable for applications requiring enhanced reliability in humid environments or elevated temperature operation.

STP16CPS05TTR and STP16DP05PTR provide higher per-channel current capacity (100mA) with extended temperature range (125°C maximum) and 30MHz frequency specification. STP16CPS05TTR maintains the 24-TSSOP package footprint identical to the original, while STP16DP05PTR uses a more compact 24-QSOP package (0.154" width) at the cost of increased MSL rating (3, 168 Hours).

TB62747AFNG,C8EL delivers the highest output voltage capability (26V) with lower per-channel current (45mA) and operates within the original temperature range (-40°C to 85°C). The 24-LSSOP package (0.220" width) provides the largest footprint among substitutes, suitable for applications prioritizing thermal dissipation or requiring maximum output voltage headroom.

Frequently Asked Questions (FAQ)

Q: Can MAX6969AUG+ directly replace TLC5948APWPR in existing designs?

A: MAX6969AUG+ is functionally compatible as a 16-output linear shift register LED driver with identical supply voltage range and package width (4.40mm). The 55mA per-channel specification is within 92% of the original 60mA rating. Verify that application LED current requirements do not exceed 55mA per channel. The superior MSL rating (1 versus 2) and extended temperature range (125°C versus 85°C) provide additional design margin.

Q: What are the key differences between STP16CPS05TTR and STP16DP05PTR?

A: Both parts deliver 100mA per-channel output with 30MHz frequency and 125°C maximum temperature. STP16CPS05TTR uses 24-TSSOP packaging (0.173" width, MSL 1) matching the original footprint density. STP16DP05PTR uses 24-QSOP packaging (0.154" width, MSL 3), providing a more compact footprint but requiring stricter moisture control during assembly (168-hour MSL window versus unlimited for STP16CPS05TTR).

Q: When should TB62747AFNG,C8EL be selected over other substitutes?

A: TB62747AFNG,C8EL is specified for applications requiring maximum output voltage capability (26V versus 10V on the original part) with lower per-channel current demands (45mA). The 24-LSSOP package (0.220" width) provides increased thermal dissipation area. Operating temperature range matches the original (-40°C to 85°C). This part is suitable for high-voltage LED string applications or designs prioritizing thermal performance over packaging density.

Q: Are all substitute parts compatible with existing PCB layouts designed for TLC5948APWPR?

A: MAX6969AUG+ and STP16CPS05TTR maintain identical package width (4.40mm, 24-TSSOP format) and are pin-compatible for direct PCB substitution. STP16DP05PTR uses a narrower 24-QSOP package (0.154" width) requiring PCB layout modification. TB62747AFNG,C8EL uses a wider 24-LSSOP package (0.220" width) and cannot be directly substituted without PCB redesign. Verify pinout compatibility and package footprint requirements before implementation.

Q: What moisture sensitivity considerations apply to each substitute?

A: MAX6969AUG+ and STP16CPS05TTR carry MSL 1 rating (unlimited shelf life), providing maximum flexibility in storage and assembly scheduling. TLC5948APWPR carries MSL 2 (1-year limit), requiring controlled storage conditions. STP16DP05PTR and TB62747AFNG,C8EL carry MSL 3 rating (168-hour limit), requiring strict moisture control during assembly and limiting shelf life to 7 days after moisture barrier bag opening.
