Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC5947DAPG4 is determined by strict equivalence across the following critical parameters:

• Number of Outputs: 24 channels (non-negotiable for pin-compatible replacement)
• Voltage Supply Range: 3V to 5.5V (must support full operating range)
• Current per Channel: 30mA (output current capability)
• Topology: Shift Register with internal switching
• Package: 32-PowerTSSOP form factor (mechanical and thermal compatibility)
• Frequency: 4MHz (signal processing capability)
• Operating Temperature Range: -40°C to 85°C (environmental compatibility)
• Compliance: ROHS3 and REACH status (regulatory requirements)

The TLC5947DAP qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The TLC5947DAP is a direct electrical and mechanical equivalent to the TLC5947DAPG4. Both devices share identical core specifications across all critical parameters: 24-output configuration, 3V to 5.5V supply range, 30mA per-channel output, 4MHz frequency, and 32-PowerTSSOP packaging.

The primary advantage of selecting TLC5947DAP is its active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current applications.

The packaging difference (tube format for TLC5947DAP versus unspecified for TLC5947DAPG4) does not affect electrical performance or PCB integration. Inventory availability for TLC5947DAP (16,536 units) significantly exceeds that of the discontinued TLC5947DAPG4 (924 units), supporting production scalability.

Frequently Asked Questions (FAQ)

Q: Can TLC5947DAP directly replace TLC5947DAPG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Pin configuration, electrical characteristics, and package dimensions are equivalent. No circuit modifications are required.

Q: Are there differences in supply voltage requirements?

A: No. Both the TLC5947DAPG4 and TLC5947DAP operate across the identical supply voltage range of 3V to 5.5V, with no derating or adjustment needed.

Q: Does the packaging format (tube) affect PCB assembly?

A: No. Tube packaging is a supply format only and does not impact electrical performance, thermal characteristics, or PCB integration. Standard surface-mount assembly processes apply to both parts.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both TLC5947DAPG4 and TLC5947DAP are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is TLC5947DAPG4 discontinued while TLC5947DAP remains active?

A: Product discontinuation decisions are manufacturer-driven and may reflect supply chain optimization or product line consolidation. The TLC5947DAP remains the active equivalent in the Texas Instruments product portfolio.

Q: What is the current availability status for each part?

A: TLC5947DAPG4 is discontinued at DiGi Electronics with 924 units in remaining stock. TLC5947DAP is active with 16,536 units in stock, providing superior supply chain security for new designs and production continuity.
