TCA6507PW LED Driver IC Equivalent & Substitute Parts

Part Overview

The TCA6507PW is a 7-output linear LED driver IC with I2C/SMBus dimming control, manufactured by Texas Instruments. This device is classified as a Power Management (PMIC) component and is currently in Last Time Buy status, indicating end-of-life production. The TCA6507PW is packaged in 14-TSSOP surface mount configuration with supply voltage range of 1.65V to 3.6V and 40mA per-channel output current capability. Due to its Last Time Buy status, identifying equivalent substitute parts with active production status is essential for long-term design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TCA6507PW is determined by strict equivalence across the following critical parameters:

• Output Configuration: 7 independent LED driver outputs
• Supply Voltage Range: 1.65V to 3.6V input tolerance
• Output Current Specification: 40mA per channel maximum
• Control Interface: I2C and SMBus protocol support
• Operating Frequency: 100kHz and 400kHz compatibility
• Package Footprint: 14-TSSOP surface mount form factor
• Temperature Rating: -40°C to 125°C operational range
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The TCA6507PWR is the direct manufacturer-recommended substitute, maintaining identical electrical specifications and package configuration while offering active production status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The TCA6507PWR is the direct equivalent substitute for the TCA6507PW. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product lifecycle status: the TCA6507PW is designated Last Time Buy, while the TCA6507PWR maintains Active production status.

For new designs or ongoing production requiring long-term component availability, the TCA6507PWR is the appropriate selection. Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The packaging difference between Tube (TCA6507PW) and Cut Tape/Digi-Reel (TCA6507PWR) does not affect electrical performance or PCB assembly compatibility, as both utilize the identical 14-TSSOP footprint.

Frequently Asked Questions (FAQ)

Q: Can the TCA6507PWR be used as a direct replacement for the TCA6507PW in existing designs?

A: Yes. The TCA6507PWR is electrically and mechanically identical to the TCA6507PW. All electrical parameters, package footprint, and pin configuration are equivalent. No design modifications are required for substitution.

Q: What is the difference between Tube and Cut Tape/Digi-Reel packaging?

A: Tube and Cut Tape/Digi-Reel are packaging and delivery formats only. They do not affect the component's electrical performance or PCB assembly compatibility. The choice between formats depends on production volume and handling requirements.

Q: Why is the TCA6507PW designated Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued standard production of this part number. Existing inventory may be available, but future availability is not guaranteed. The TCA6507PWR provides continuity for ongoing production requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the TCA6507PW and TCA6507PWR maintain identical ROHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and ECCN/HTSUS classifications.

Q: What is the minimum supply voltage requirement for these LED driver ICs?

A: The minimum supply voltage is 1.65V. The maximum supply voltage is 3.6V. Operation outside this range may result in device malfunction or damage.

Q: Can these parts support both I2C and SMBus protocols simultaneously?

A: Yes. The TCA6507PW and TCA6507PWR support both I2C and SMBus dimming control protocols. The specific protocol used depends on system design and firmware implementation.
