The THS4061IDR meets all substitution criteria and is identified as the manufacturer-recommended equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The THS4061IDR is the direct substitute for the discontinued THS4061IDRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications and mechanical package dimensions.

Selection Basis:

The THS4061IDR maintains active product status with Texas Instruments, ensuring long-term availability and supply chain reliability. Both parts comply with ROHS3 standards and carry identical moisture sensitivity ratings, confirming environmental and regulatory compatibility.

The primary difference between the two parts is packaging format: the THS4061IDRG4 is supplied in tube packaging, while the THS4061IDR is supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical performance or mechanical compatibility in PCB assembly applications. The Tape & Reel format of the substitute part is standard for automated surface mount assembly processes.

For applications currently using the THS4061IDRG4, direct substitution with the THS4061IDR is electrically and mechanically valid without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)
