TLC5615IDRG4 Equivalent & Substitute Parts

Part Overview

The TLC5615IDRG4 is a 10-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring voltage output conversion. This device features a single DAC channel with SPI interface, external reference capability, and buffered voltage output in an 8-SOIC surface mount package.

The TLC5615IDRG4 is discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC5615IDRG4 is determined by strict equivalence across the following critical parameters:

• Resolution: 10-bit conversion capability
• Channel Count: Single DAC channel
• Output Configuration: Buffered voltage output
• Interface Protocol: SPI digital interface
• Reference Input: External reference requirement
• Supply Voltages: 5V analog and digital supplies
• Accuracy Specifications: INL/DNL performance (±1 Max, ±0.1)
• Settling Time: 12.5µs typical response
• Package Type: 8-SOIC surface mount form factor
• Temperature Range: -40°C to 85°C operation
• Compliance: ROHS3 and REACH requirements

The TLC5615IDR meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The TLC5615IDR is a direct parametric equivalent to the TLC5615IDRG4. Both devices are manufactured by Texas Instruments and share identical electrical specifications, package configuration, and compliance certifications.

The primary distinction is product status: the TLC5615IDRG4 is discontinued, while the TLC5615IDR maintains active status with current inventory availability (23,400 pcs). Both parts meet ROHS3 and REACH compliance requirements.

For applications currently specified with TLC5615IDRG4, the TLC5615IDR provides full functional and electrical compatibility without design modification. The packaging difference (Digi-Reel® vs. standard packaging) does not affect electrical performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can TLC5615IDR replace TLC5615IDRG4 in existing designs?

A: Yes. The TLC5615IDR is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required.

Q: What is the difference between TLC5615IDRG4 and TLC5615IDR?

A: The devices are electrically identical. The primary difference is packaging format (Digi-Reel® for TLC5615IDR) and product status (discontinued vs. active). The TLC5615IDRG4 suffix indicates a specific packaging configuration from DiGi Electronics.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance, REACH status, and moisture sensitivity ratings (MSL 1).

Q: What is the 8-SOIC package specification?

A: The 8-SOIC (Small Outline Integrated Circuit) package measures 0.154 inches (3.90mm) in width and is a standard surface mount form factor. Both substitute parts use this identical package.

Q: Can I use TLC5615IDR in high-temperature applications?

A: Both parts operate across the -40°C to 85°C temperature range. Applications requiring operation beyond 85°C require alternative device selection.

Q: What is the significance of the external reference requirement?

A: Both devices require an external voltage reference for DAC operation. The reference voltage determines the output range and must be supplied by the application circuit.
