TLC5923DAPRG4 Equivalent & Substitute Parts

Part Overview

The TLC5923DAPRG4 is a 16-output linear LED driver IC manufactured by Texas Instruments, designed for backlight applications requiring precise current control at 80mA per channel. This device integrates a shift register topology with internal switching capability, operating across a 3V to 5.5V supply range with a maximum output voltage of 17V.

The TLC5923DAPRG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. The substitute part maintains identical electrical and mechanical specifications while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC5923DAPRG4 is determined by strict equivalence across the following critical parameters:

• 16 output channels with 80mA per-channel current rating
• 3V to 5.5V supply voltage range
• 17V maximum output voltage
• 30MHz frequency specification
• Linear shift register topology with internal switching
• 32-PowerTSSOP package configuration
• Operating temperature range of -40°C to 85°C

The TLC5923DAPR meets all substitution criteria, providing identical electrical performance and mechanical compatibility while maintaining the same base product number (TLC5923) and package designation (32-HTSSOP).

Parameter Comparison

Engineering Selection Recommendations

The TLC5923DAPR is the direct substitute for the discontinued TLC5923DAPRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package configuration, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The primary distinction is product status: the TLC5923DAPRG4 is discontinued, while the TLC5923DAPR maintains active status with significantly higher inventory availability (19,300 units versus 3,900 units). For new designs and ongoing production requirements, the TLC5923DAPR is the recommended selection to ensure long-term supply continuity and component availability.

Both parts are supplied in 32-HTSSOP packaging and are suitable for direct PCB substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the TLC5923DAPR be used as a direct replacement for the TLC5923DAPRG4?

A: Yes. Both parts are electrically and mechanically identical, sharing the same 16-output configuration, 80mA per-channel current rating, 3V to 5.5V supply range, and 32-PowerTSSOP package. No circuit redesign is required.

Q: What is the difference between TLC5923DAPRG4 and TLC5923DAPR?

A: The parts are functionally equivalent. The primary difference is product lifecycle status: TLC5923DAPRG4 is discontinued, while TLC5923DAPR is active with higher inventory availability.

Q: Are there any package or pinout differences?

A: No. Both parts use the 32-PowerTSSOP (0.240", 6.10mm Width) package with identical pinout and mechanical dimensions. PCB footprints are interchangeable.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the TLC5923DAPRG4 and TLC5923DAPR are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 3, with a floor life of 168 hours. Standard moisture control procedures apply during storage and handling.
