TLC5920DLRG4 Equivalent & Substitute Parts

Part Overview

The TLC5920DLRG4 is a 16-output linear LED driver IC manufactured by Texas Instruments, designed for shift register-based dimming applications. This device operates within a 4.5V to 5.5V supply range and delivers 30mA per output channel at a maximum frequency of 10MHz. The part is housed in a 48-BSSOP surface mount package.

The TLC5920DLRG4 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC5920DLRG4 is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Linear shift register topology with 16 outputs
• Electrical Specifications: 4.5V to 5.5V supply voltage range, 30mA per-channel output current, 10MHz maximum frequency
• Thermal Operating Range: -20°C to 85°C ambient temperature
• Physical Package: 48-BSSOP surface mount configuration with 0.295" (7.50mm) width
• Regulatory Compliance: ROHS3 compliance, REACH unaffected status, MSL 2 rating

The TLC5920DLR meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TLC5920DLR is the direct substitute for the discontinued TLC5920DLRG4. Both parts are manufactured by Texas Instruments and share identical electrical, thermal, and mechanical specifications. The TLC5920DLR maintains active product status and is available in higher inventory quantities, making it the appropriate selection for new designs and component replenishment.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The MSL 2 moisture sensitivity rating applies to both variants, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the TLC5920DLR be used as a direct replacement for the TLC5920DLRG4?

A: Yes. The TLC5920DLR is electrically and mechanically identical to the TLC5920DLRG4. All functional parameters, supply voltage range, output current specifications, frequency rating, operating temperature range, and package configuration are equivalent.

Q: Are there any differences in packaging or handling between these parts?

A: The TLC5920DLR is available in Cut Tape (CT) and Digi-Reel packaging options, whereas the TLC5920DLRG4 packaging format is not specified in the available data. Both parts use the 48-BSSOP package with identical physical dimensions. Both require MSL 2 moisture control (1 Year storage life).

Q: What is the significance of the product status difference?

A: The TLC5920DLRG4 is discontinued at DiGi Electronics, meaning it is no longer actively stocked or supported through that distribution channel. The TLC5920DLR maintains active status and is available in production quantities, making it the recommended selection for ongoing applications.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. No additional certifications or compliance considerations differentiate these parts.
