TLC071CP Equivalent & Substitute Parts

Part Overview

The TLC071CP is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This device is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory (1157 pcs). The TLC071CP serves applications requiring low-power, general-purpose amplification with moderate bandwidth and slew rate characteristics. Identifying equivalent substitute parts is necessary due to the product's end-of-life status and potential future availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC071CP is determined by electrical parameter equivalence and package compatibility. The primary substitute identified is the TLC071CDR, which maintains identical electrical specifications across all critical parameters: slew rate (19 V/µs), gain bandwidth product (10 MHz), input bias current (1.5 pA), input offset voltage (390 µV), supply current (2.1 mA), output current per channel (57 mA), and supply voltage range (4.5 V to 16 V). Both devices share the same base product number (TLC071) and manufacturer (Texas Instruments).

The key differentiator between these parts is the package format: the TLC071CP uses through-hole 8-DIP packaging, while the TLC071CDR uses surface-mount 8-SOIC packaging. This distinction affects board-level integration and assembly methodology but does not alter electrical performance or functional compatibility in circuit design.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The TLC071CDR carries Active product status with significantly higher inventory availability (7967 pcs), contrasting with the Last Time Buy status of the TLC071CP.

Parameter Comparison

Engineering Selection Recommendations

The TLC071CDR is the direct electrical equivalent to the TLC071CP and is suitable for substitution in applications where circuit topology and electrical performance are the primary selection criteria. All analog specifications, supply voltage requirements, and operating temperature ranges are identical between the two devices.

Selection between these parts depends on assembly methodology and board design constraints:

TLC071CP (Through-Hole 8-DIP): Appropriate for through-hole assembly processes, breadboard prototyping, and legacy board designs. Product status is Last Time Buy, indicating limited future availability.

TLC071CDR (Surface-Mount 8-SOIC): Appropriate for surface-mount assembly processes and modern PCB designs. Product status is Active with substantially higher inventory availability (7967 pcs versus 1157 pcs), supporting long-term supply chain continuity.

Both parts maintain identical regulatory compliance (ROHS3 Compliant, REACH Unaffected), ensuring no additional qualification requirements for substitution. The choice between these parts should be driven by existing assembly infrastructure and long-term production volume requirements rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Are the TLC071CP and TLC071CDR electrically interchangeable?

A: Yes. Both devices share identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. They are derived from the same base product (TLC071) and manufactured by Texas Instruments.

Q: What is the primary difference between these two parts?

A: The primary difference is packaging format. The TLC071CP uses through-hole 8-DIP packaging (0.300" width), while the TLC071CDR uses surface-mount 8-SOIC packaging (0.154" width). This affects PCB assembly methodology but not circuit functionality.

Q: Can I use the TLC071CDR as a direct replacement for the TLC071CP on an existing board?

A: Direct board-level replacement is not possible without PCB redesign. The TLC071CP requires through-hole footprints, while the TLC071CDR requires surface-mount footprints. However, both devices can be used in new designs with appropriate footprint selection.

Q: Why is the TLC071CP marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part. Existing inventory is limited (1157 pcs), and no future production is planned. The TLC071CDR, with Active status and higher inventory (7967 pcs), is recommended for new designs requiring long-term availability.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the TLC071CP and TLC071CDR are ROHS3 Compliant and REACH Unaffected, meeting identical environmental and regulatory standards.

Q: What is the moisture sensitivity level difference between these parts?

A: The TLC071CP has Not Applicable moisture sensitivity level (through-hole package). The TLC071CDR has MSL 1 (Unlimited) moisture sensitivity level (surface-mount package). This affects storage and handling procedures for the surface-mount variant but does not impact electrical performance.
