Engineering Selection Recommendations

TS27L4CDT Selection Criteria:

The TS27L4CDT is suitable for applications operating within the 0°C to 70°C temperature range. This substitute maintains identical slew rate performance and comparable gain bandwidth product specifications. The device is supplied in Cut Tape (CT) packaging and carries active product status with ROHS3 compliance. The minimum supply voltage requirement of 3 V represents a constraint for applications requiring operation below this threshold.

TS27L4IDT Selection Criteria:

The TS27L4IDT extends the operating temperature range to -40°C to 125°C, accommodating industrial and extended-temperature applications. This variant is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. The TS27L4IDT maintains identical electrical performance characteristics to the TS27L4CDT while providing broader environmental operating conditions. Active product status and ROHS3 compliance are maintained.

Substitution Compatibility:

Both substitute parts are electrically compatible with the TLC25L4ACD within the overlapping supply voltage range of 3 V to 16 V. The 14-SOIC package footprint is identical, permitting direct board-level substitution without layout modifications. All three devices maintain ROHS3 compliance and are classified under the same HTSUS and ECCN categories.

Frequently Asked Questions (FAQ)

Q: Can the TS27L4CDT or TS27L4IDT be used as direct replacements for the TLC25L4ACD?

A: Both TS27L4CDT and TS27L4IDT are electrically compatible substitutes within the overlapping supply voltage range of 3 V to 16 V. The identical 14-SOIC package permits direct board-level substitution. Applications requiring supply voltages below 3 V require design modification or alternative component selection.

Q: What is the primary difference between TS27L4CDT and TS27L4IDT?

A: The TS27L4IDT operates across an extended temperature range of -40°C to 125°C, compared to the TS27L4CDT range of 0°C to 70°C. Both devices maintain identical electrical performance specifications. Selection depends on application temperature requirements.

Q: Are there packaging differences between the substitute parts?

A: The TS27L4CDT is supplied in Cut Tape (CT) packaging. The TS27L4IDT is available in both Cut Tape (CT) and Digi-Reel® packaging formats. Both utilize the identical 14-SOIC case outline, ensuring footprint compatibility.

Q: What supply voltage considerations apply when substituting the TLC25L4ACD?

A: The TLC25L4ACD operates from 1.4 V minimum supply voltage, while both substitute parts require a minimum of 3 V. Applications designed for supply voltages between 1.4 V and 3 V cannot use the TS27L4CDT or TS27L4IDT without circuit redesign. The maximum supply voltage of 16 V is identical across all three devices.

Q: Do the substitute parts maintain RoHS compliance?

A: Both TS27L4CDT and TS27L4IDT are ROHS3 compliant, matching the compliance status of the TLC25L4ACD. All three devices are classified as REACH Unaffected.

Q: What is the inventory status of the substitute parts?

A: The TS27L4CDT has 30,200 pieces in stock, and the TS27L4IDT has 23,400 pieces in stock, both classified as new original inventory. The TLC25L4ACD, as an obsolete product, has limited availability at 700 pieces.
