Substitute Part Grouping Explanation

Substitution of the TL080CPG4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: J-FET input architecture
• Number of Circuits: Single operational amplifier per package
• Slew Rate: 13V/µs minimum
• Gain Bandwidth Product: 3 MHz minimum
• Current - Input Bias: 30 pA maximum
• Voltage - Supply Span: 7V to 36V operating range
• Operating Temperature: 0°C to 70°C minimum coverage

Mechanical Equivalence Criteria:

• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Supplier Device Package: 8-PDIP

The TL081BCP meets all electrical and mechanical equivalence requirements and maintains full pin-for-pin compatibility with the TL080CPG4. The primary distinction is the product status transition from obsolete to active, enabling continued procurement and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The TL081BCP is the direct substitute for the TL080CPG4 based on the following engineering criteria:

Product Status Alignment: The TL081BCP maintains active product status with Texas Instruments, ensuring long-term availability, supply chain continuity, and manufacturer technical support. The TL080CPG4 is classified as obsolete, creating procurement risk and limiting access to new inventory.

Electrical Performance: All critical electrical parameters are identical between the two devices. The TL081BCP exhibits a marginally improved input offset voltage specification (2 mV versus 3 mV), which represents a performance enhancement rather than a limitation.

Compliance Certification: Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Mechanical Compatibility: Pin-for-pin compatibility is confirmed through identical 8-DIP package geometry, through-hole mounting configuration, and supplier device package designation (8-PDIP).

Supply Chain Availability: Current inventory of TL081BCP (2100 pieces) exceeds that of TL080CPG4 (1096 pieces), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Is the TL081BCP a direct pin-for-pin replacement for the TL080CPG4?

A: Yes. Both devices utilize the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout configuration. No circuit board modifications are required for substitution.

Q: What is the primary reason for substituting the TL080CPG4?

A: The TL080CPG4 is classified as obsolete. The TL081BCP is an active product offering equivalent electrical performance with assured long-term availability and manufacturer support.

Q: Are there any electrical performance differences between these devices?

A: All core electrical parameters are identical. The TL081BCP specifies a lower input offset voltage (2 mV versus 3 mV), representing improved performance characteristics.

Q: Do both devices meet the same regulatory compliance standards?

A: Yes. Both the TL080CPG4 and TL081BCP are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements.

Q: Can the TL081BCP be used in existing circuit designs without modification?

A: Yes. Electrical equivalence across all specified parameters and mechanical pin-for-pin compatibility enable direct substitution without circuit redesign or board layout changes.

Q: What is the operating temperature range for both devices?

A: Both devices operate across the 0°C to 70°C temperature range, supporting equivalent thermal performance in industrial and commercial environments.

Q: Are there packaging differences between the two parts?

A: Both devices are supplied in 8-DIP through-hole packages. The TL081BCP is packaged in tubes, while the TL080CPG4 packaging specification is not provided. This does not affect electrical or mechanical compatibility.
