Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC5940PWPRG4 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Manufacturer: Texas Instruments
• Number of Outputs: 16
• Current - Output / Channel: 120mA
• Voltage - Supply Range: 3V to 5.5V
• Voltage - Output: 17V
• Frequency: 30MHz
• Package / Case: 28-PowerTSSOP
• Operating Temperature: -40°C ~ 85°C (TA)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)

All identified substitute parts match these parameters exactly. Variations in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) and product status do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TLC59401PWPR and TLC5940PWPR are direct electrical and mechanical equivalents to the discontinued TLC5940PWPRG4. Selection between these substitutes should be based on the following factors:

TLC59401PWPR is supplied in Tape & Reel (TR) packaging format and maintains Active product status. This variant is suitable for high-volume production environments where reel-based component handling is standard.

TLC5940PWPR is supplied in Cut Tape (CT) & Digi-Reel® packaging format and maintains Active product status. This variant accommodates both cut tape and reel-based procurement workflows, providing flexibility for varying order quantities.

Both parts carry identical electrical specifications, thermal ratings, compliance certifications (ROHS3, REACH Unaffected), and moisture sensitivity classifications. The choice between them depends solely on procurement requirements and assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Are TLC59401PWPR and TLC5940PWPR electrically identical to TLC5940PWPRG4?

A: Yes. Both substitute parts match all critical electrical parameters: 16 outputs, 120mA per-channel current, 3V to 5.5V supply voltage range, 17V output voltage, 30MHz frequency, and -40°C to 85°C operating temperature range.

Q: What is the difference between the packaging formats?

A: TLC59401PWPR is supplied in Tape & Reel (TR) format, optimized for automated assembly lines. TLC5940PWPR is supplied in Cut Tape (CT) & Digi-Reel® format, supporting both manual and automated handling. Electrical performance is identical.

Q: Can I use these substitutes in existing PCB designs without modification?

A: Yes. All three parts use the identical 28-PowerTSSOP package with matching pin configurations and thermal characteristics. No PCB layout changes are required.

Q: Are compliance certifications maintained across all variants?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level (MSL) ratings of 2 (1 Year).

Q: Why is the original TLC5940PWPRG4 discontinued?

A: Product discontinuation decisions are manufacturer-driven. Active equivalents TLC59401PWPR and TLC5940PWPR provide identical functionality and are recommended for new designs and component replacement.
