Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC274IDRCT are grouped strictly by identical or matching key electrical and mechanical parameters. The allowed substitution is determined by:

• Amplifier Type
• Number of Circuits
• Gain Bandwidth Product
• Supply Current and Output Current per Channel
• Voltage Supply Range
• Operating Temperature Range
• Package / Case and Mounting Type
• RoHS and REACH compliance
• Moisture Sensitivity Level

Only parts that match or exceed all the above parameters are included in the substitute list.

Parameter Comparison

Engineering Selection Recommendations

Substitution of the TLC274IDRCT with TLC274IDR is supported based on provided parameters, RoHS3 compliance, REACH unaffected status, and identical form factor and packaging standards. TLC274IDR is designated as "Active," facilitating continuity of supply. Moisture Sensitivity Level remains at level 1 (unlimited), matching the requirements for standard surface mount manufacturing.

Frequently Asked Questions (FAQ)

Q1: What are the most important criteria when substituting TLC274IDRCT?
A1: Key criteria include matching amplifier type, number of circuits, slew rate, gain bandwidth product, supply current, output current, voltage supply range, operating temperature, package/case, and compliance statuses.

Q2: Is TLC274IDR a direct replacement for TLC274IDRCT in terms of footprint and pinout?
A2: Both parts share the 14-SOIC package (0.154", 3.90mm width), surface-mount type, and supplier device package, supporting direct mechanical interchange.

Q3: Are there any packaging or compliance differences to consider?
A3: Both parts are ROHS3 compliant and REACH unaffected, with Moisture Sensitivity Level 1 (unlimited). Packaging form naming may vary (Tape & Reel versus standard), but device compatibility is maintained.

Q4: Is the electrical performance of TLC274IDR within the limits specified for TLC274IDRCT?
A4: Based on provided parameters, TLC274IDR aligns closely with TLC274IDRCT in all critical electrical characteristics except for a slightly lower slew rate and higher supply current.

Q5: Does the "Last Time Buy" status of TLC274IDRCT impact ongoing product development?
A5: "Last Time Buy" status indicates future availability constraints for TLC274IDRCT, making immediate identification and adoption of substitute parts essential for uninterrupted supply.
