TLV2461IP Equivalent & Substitute Parts

Part Overview

The TLV2461IP is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This device features rail-to-rail output capability and is designed for low-power applications requiring single-circuit amplification. The TLV2461IP is currently in Last Time Buy status, indicating discontinued production. Identification of equivalent and substitute parts is necessary to ensure design continuity and procurement availability for new production runs and long-term system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV2461IP is determined by the following criteria:

Primary Compatibility Requirements:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Secondary Compatibility Parameters:

• Voltage - Supply Span (Min): ≥ 2.7 V
• Voltage - Supply Span (Max): ≥ 6 V
• Operating Temperature Range: Must encompass or exceed -40°C to 125°C for extended-temperature applications

Acceptable Variation Parameters:

• Slew Rate: Higher values acceptable (improved performance)
• Gain Bandwidth Product: Higher values acceptable (improved performance)
• Current - Input Bias: Lower values acceptable (improved performance)
• Voltage - Input Offset: Lower values acceptable (improved performance)
• Current - Supply: Lower values acceptable (improved efficiency)
• Current - Output / Channel: Lower values acceptable if application requirements are met

The substitute parts TLV2461CP, MCP6281-E/P, and MCP6283-E/P satisfy all primary compatibility requirements and maintain functional equivalence within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

TLV2461CP (Texas Instruments)

The TLV2461CP is the direct Texas Instruments equivalent to the TLV2461IP, maintaining identical electrical specifications and package configuration. This part is currently in Active product status, ensuring long-term availability and supply chain stability. The TLV2461CP is suitable for applications where the operating temperature range does not exceed 0°C to 70°C. Both parts are ROHS3 compliant and REACH unaffected. Selection of TLV2461CP is recommended for designs requiring continuity with the original TLV2461IP specification while maintaining manufacturer consistency.

MCP6281-E/P and MCP6283-E/P (Microchip Technology)

The MCP6281-E/P and MCP6283-E/P are functionally equivalent alternatives manufactured by Microchip Technology. Both devices maintain the same package configuration (8-DIP through-hole) and rail-to-rail output capability. These parts offer improved performance characteristics: higher slew rate (2.5 V/µs versus 1.6 V/µs), lower input bias current (1 pA versus 1.3 nA), and lower supply current (450 µA versus 550 µA). Both MCP6281-E/P and MCP6283-E/P support the full extended temperature range (-40°C to 125°C), matching the original TLV2461IP specification. Both parts are ROHS3 compliant and REACH unaffected. These devices are suitable for applications requiring extended temperature operation and improved electrical performance. The MCP6281-E/P and MCP6283-E/P are currently in Active product status.

Temperature Range Consideration

Applications requiring operation across the full -40°C to 125°C temperature range must use either the TLV2461IP, MCP6281-E/P, or MCP6283-E/P. The TLV2461CP is limited to 0°C to 70°C operation and is not suitable for extended-temperature applications.

Output Current Consideration

Applications requiring output current exceeding 25 mA per channel must use the TLV2461IP or TLV2461CP, which provide 80 mA output capability. The MCP6281-E/P and MCP6283-E/P are limited to 25 mA output per channel.

Frequently Asked Questions (FAQ)

Q: Can the TLV2461CP directly replace the TLV2461IP in all applications?

A: The TLV2461CP is electrically equivalent to the TLV2461IP and uses the same 8-DIP package. However, the TLV2461CP operating temperature range is limited to 0°C to 70°C, compared to the TLV2461IP range of -40°C to 125°C. Direct substitution is valid only for applications operating within the 0°C to 70°C temperature window.

Q: What are the key differences between the TLV2461IP and the Microchip MCP6281-E/P?

A: Both devices are functionally equivalent in package and basic operation. The MCP6281-E/P offers improved performance: slew rate of 2.5 V/µs (versus 1.6 V/µs), input bias current of 1 pA (versus 1.3 nA), and supply current of 450 µA (versus 550 µA). The MCP6281-E/P supports the full -40°C to 125°C temperature range. The primary limitation is reduced output current capability: 25 mA per channel versus 80 mA for the TLV2461IP.

Q: Are MCP6281-E/P and MCP6283-E/P interchangeable?

A: The MCP6281-E/P and MCP6283-E/P share identical electrical specifications and package configuration. Both devices are functionally interchangeable from an engineering perspective. Selection between these two parts should be based on supplier availability and inventory status.

Q: What is the significance of the Last Time Buy status for the TLV2461IP?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLV2461IP. Existing inventory will be depleted, and no new production runs are planned. For new designs or long-term production requirements, selection of an active substitute part (TLV2461CP, MCP6281-E/P, or MCP6283-E/P) is necessary to ensure supply chain continuity.

Q: Can I use MCP6281-E/P or MCP6283-E/P in a high-current output application requiring 80 mA?

A: No. The MCP6281-E/P and MCP6283-E/P are limited to 25 mA output per channel. Applications requiring 80 mA output capability must use the TLV2461IP or TLV2461CP.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TLV2461IP, TLV2461CP, MCP6281-E/P, and MCP6283-E/P are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part should I select for a new design?

A: For new designs, select from the Active product status parts: TLV2461CP (if operating temperature ≤ 70°C and output current ≤ 80 mA), or MCP6281-E/P / MCP6283-E/P (if extended temperature operation or improved performance is required, with output current ≤ 25 mA). Avoid the TLV2461IP due to Last Time Buy status.
