TL071IPG4 Equivalent & Substitute Parts

Part Overview

The TL071IPG4 is a J-FET input operational amplifier manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This device is classified as obsolete, though 701 units remain available in new original stock. The TL071IPG4 serves applications requiring low input bias current and stable gain-bandwidth characteristics across industrial and commercial temperature ranges. Due to its obsolete status, identifying equivalent active production alternatives is essential for design continuity and long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the TL071IPG4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: J-FET input architecture
• Number of Circuits: Single circuit configuration
• Slew Rate: 13 V/µs
• Gain Bandwidth Product: 5.25 MHz
• Input Bias Current: 65 pA
• Input Offset Voltage: 3 mV
• Supply Current: 1.4 mA
• Supply Voltage Range: 10 V to 30 V
• Operating Temperature: -40°C to 85°C

Mechanical Equivalence Criteria:

• Package Type: 8-DIP through-hole
• Pin Configuration: 8-PDIP standard

The TL071IP qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status: TL071IPG4 is obsolete, while TL071IP maintains active production status with significantly higher inventory availability (1148 units versus 701 units).

Engineering Selection Recommendations

Primary Substitute: TL071IP

The TL071IP is the direct equivalent for the TL071IPG4 across all electrical and mechanical parameters. Selection of TL071IP is justified on the following grounds:

1. Product Status: TL071IP maintains active production status, ensuring long-term availability and supply chain continuity. The TL071IPG4 is classified as obsolete.

2. Regulatory Compliance: Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.

3. Electrical Equivalence: All critical parameters—slew rate, gain-bandwidth product, input bias current, input offset voltage, supply current, and operating temperature range—are identical.

4. Mechanical Compatibility: Both devices utilize the 8-DIP through-hole package with identical pin spacing (0.300", 7.62mm), enabling direct board-level substitution without layout modification.

5. Inventory Availability: TL071IP stock (1148 units) exceeds TL071IPG4 availability (701 units), supporting procurement reliability.

For applications currently specified with TL071IPG4, direct substitution with TL071IP requires no circuit redesign or performance trade-offs.
