TLV2442AIPWR Equivalent & Substitute Parts

Part Overview

The TLV2442AIPWR is an active linear amplifier integrated circuit manufactured by Texas Instruments, classified as a CMOS dual-channel rail-to-rail operational amplifier in an 8-TSSOP surface mount package. This device is in active product status and is designed for general-purpose amplification applications requiring low power consumption and rail-to-rail output capability.

Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical constraints of the application. Substitution becomes necessary due to inventory availability, supply chain considerations, or design flexibility requirements while maintaining compatibility with existing PCB layouts and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2442AIPWR is determined by the following critical parameters that must be maintained or exceeded:

Mechanical Compatibility:

• Package type must be 8-TSSOP with identical pin configuration and 0.173" (4.40mm) width
• Surface mount mounting type required for PCB assembly compatibility

Electrical Compatibility:

• Dual-channel (2 circuits) configuration mandatory
• Rail-to-rail output capability required
• Operating temperature range must encompass -40°C to 85°C minimum
• Supply voltage range must support operation within 2.7V to 10V span

Regulatory & Environmental Compliance:

• ROHS3 compliance required
• MSL rating of 1 (Unlimited) acceptable
• Active product status preferred for long-term availability

The OP279GRUZ-REEL from Analog Devices Inc. satisfies these substitution criteria through identical package geometry, dual-channel configuration, rail-to-rail output specification, and matching compliance certifications. Functional differences in amplifier type (Buffer vs. CMOS) and electrical performance parameters do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (TLV2442AIPWR): The TLV2442AIPWR remains the primary component choice for applications requiring operation at supply voltages below 4.5V. This device supports a minimum supply voltage of 2.7V, enabling deployment in battery-powered and low-voltage systems. The part is in active product status with established supply chain presence (3900 units in stock). ROHS3 compliance and MSL-1 rating confirm suitability for standard manufacturing and storage conditions.

Substitute Selection (OP279GRUZ-REEL): The OP279GRUZ-REEL from Analog Devices Inc. is a qualified substitute for applications where supply voltage remains at or above 4.5V. This device maintains identical package geometry, dual-channel configuration, and rail-to-rail output capability. Active product status and matching compliance certifications (ROHS3, MSL-1) ensure equivalent reliability and manufacturability. The substitute is available in Cut Tape and Digi-Reel packaging formats (1645 units in stock).

Substitution Constraints: Substitution of TLV2442AIPWR with OP279GRUZ-REEL is restricted to designs where the minimum supply voltage requirement is 4.5V or higher. Applications requiring operation below 4.5V must retain the TLV2442AIPWR. Pin-to-pin compatibility and identical package dimensions permit direct PCB layout reuse without modification.

Frequently Asked Questions (FAQ)

Q: Can the OP279GRUZ-REEL replace the TLV2442AIPWR in all applications?

A: No. The OP279GRUZ-REEL has a minimum supply voltage requirement of 4.5V, compared to 2.7V for the TLV2442AIPWR. Substitution is valid only for designs operating at 4.5V or above. Applications requiring lower supply voltages must use the TLV2442AIPWR.

Q: Are the packages physically identical?

A: Yes. Both devices use the 8-TSSOP package with 0.173" (4.40mm) width. Pin configuration and PCB footprint are identical, permitting direct substitution without layout modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TLV2442AIPWR and OP279GRUZ-REEL are ROHS3 compliant with MSL-1 (Unlimited) moisture sensitivity rating. Both are in active product status, ensuring continued availability and support.

Q: What is the difference between CMOS and Buffer amplifier types?

A: The TLV2442AIPWR is classified as a CMOS amplifier, while the OP279GRUZ-REEL is classified as a Buffer amplifier. Both provide dual-channel rail-to-rail output capability. The functional difference does not preclude substitution when application requirements are met.

Q: Can I use the substitute part in a design originally specified for the TLV2442AIPWR?

A: Substitution is permitted only if the design supply voltage is 4.5V or higher. Verify that all other electrical parameters (output current, operating temperature, etc.) are compatible with your application requirements before implementing the substitute.

Q: What packaging formats are available for each part?

A: The TLV2442AIPWR is supplied in standard surface mount packaging. The OP279GRUZ-REEL is available in Cut Tape (CT) and Digi-Reel® formats, providing flexibility for different assembly and procurement workflows.
