TL3414AIP Equivalent & Substitute Parts

Part Overview

The TL3414AIP is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-pin DIP package. This component is classified as obsolete, indicating discontinued production and limited availability in the market. The TL3414AIP operates across a wide supply voltage range (3V to 15V) and is suitable for general-purpose analog signal processing applications requiring moderate bandwidth and low input bias current characteristics.

Due to its obsolete status, identifying functionally equivalent substitute parts with active production status is essential for design continuity and long-term component sourcing reliability.

Substitute Part Grouping Explanation

Substitution of the TL3414AIP is determined by strict equivalence across all electrical performance parameters and functional specifications. The following criteria establish valid substitution:

Electrical Parameter Equivalence:

• Amplifier type: General Purpose (identical function)
• Number of circuits: 2 (dual-channel configuration)
• Slew rate: 1.3 V/µs (identical)
• Gain bandwidth product: 2 MHz (identical)
• Input bias current: 300 nA (identical)
• Input offset voltage: 2 mV (identical)
• Supply current: 4 mA (identical)
• Output current per channel: 70 mA (identical)
• Supply voltage range: 3V to 15V (identical)
• Operating temperature: -40°C to 85°C (identical)

Functional Basis: The TL3414AIP and its substitute share the same base product number (TL3414), confirming identical die and electrical performance. Substitution is valid when all electrical parameters match exactly and the part maintains compliance with applicable standards (RoHS3, REACH).

Package Consideration: While the TL3414AIP uses through-hole mounting (8-DIP), substitute parts may employ surface-mount technology (8-SOIC). Package selection depends on circuit board design and assembly capabilities, not electrical performance.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The TL3414AIP is classified as obsolete with limited inventory availability (1225 pieces). The TL3414AIDR is the manufacturer-recommended substitute, maintaining active production status with significantly higher inventory (18617 pieces). Both parts are manufactured by Texas Instruments and share identical electrical specifications.

Compliance and Certification: Both the TL3414AIP and TL3414AIDR maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications. No compliance barriers exist for substitution.

Package Selection Criteria: The primary difference between these parts is packaging technology. Selection between through-hole (8-DIP) and surface-mount (8-SOIC) configurations depends on circuit board design, assembly equipment, and manufacturing process. Electrical performance is independent of package type.

Supply Chain Considerations: The TL3414AIDR is the active production part and represents the long-term sourcing solution. For new designs or redesigns, the TL3414AIDR is the appropriate selection. For existing through-hole designs requiring immediate replacement, evaluate board-level modifications to accommodate surface-mount technology or confirm alternative through-hole options through the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the TL3414AIDR directly replace the TL3414AIP in an existing circuit?

A: Electrical substitution is complete; all performance parameters are identical. However, package compatibility must be evaluated. The TL3414AIP uses through-hole mounting (8-DIP), while the TL3414AIDR uses surface-mount technology (8-SOIC). Direct socket replacement is not possible without board redesign or adapter solutions.

Q: Why is the TL3414AIP classified as obsolete?

A: Obsolete status indicates Texas Instruments has discontinued production of this part number. The TL3414AIDR represents the active production equivalent, ensuring continued availability and manufacturing support.

Q: Are there electrical performance differences between the TL3414AIP and TL3414AIDR?

A: No. Both parts share the same base product number (TL3414) and maintain identical electrical specifications across all measured parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range.

Q: What is the inventory status of these parts?

A: The TL3414AIP has 1225 pieces in stock (obsolete status). The TL3414AIDR has 18617 pieces in stock (active production). For long-term sourcing, the TL3414AIDR is the recommended selection.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the TL3414AIP and TL3414AIDR are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What factors should determine package selection between 8-DIP and 8-SOIC?

A: Package selection is determined by circuit board design and manufacturing capabilities. Through-hole (8-DIP) is suitable for breadboarding, prototyping, and designs with existing through-hole infrastructure. Surface-mount (8-SOIC) is appropriate for high-density PCB layouts and automated assembly processes. Electrical performance is independent of package choice.
