LM8261M5 Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments LM8261M5 is a general-purpose operational amplifier in the Linear, Amplifiers category. It features a single rail-to-rail output amplifier circuit within a SOT-23-5 package. The device is specified with a slew rate of 12V/µs, a gain bandwidth product of 24 MHz, and operates across a supply span of 2.5 V to 30 V. The LM8261M5 is currently listed as obsolete, making it necessary to identify equivalent or substitute operational amplifiers that meet its published electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based exclusively on the matching of the following explicit parameters: amplifier type, number of amplifier circuits, output type, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, supply voltage span, operating temperature range, mounting type, package/case, supplier device package, RoHS status, and MSL. Only parts with congruent or directly comparable values for these parameters are listed as substitutes. These criteria ensure compatibility in performance and footprint for direct replacement in applications originally designed for the LM8261M5.

Parameter Comparison

Engineering Selection Recommendations

The LM8261M5 is listed as obsolete. All substitute parts are active and are RoHS3 compliant, in contrast to the main part's RoHS non-compliant status. Substitute parts ADA4084-1ARJZ-R2, ADA4084-1ARJZ-R7, ADA4084-1ARJZ-RL, and LM8261M5X/NOPB provide enhanced environmental compliance. Moisture Sensitivity Level (MSL) is consistent across all evaluated parts at 1 (Unlimited). All listed substitutes feature an identical package and mounting type, as well as matched or comparable electrical parameters within the allowed substitution range as detailed above.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting a substitute for the LM8261M5?
A1: Substitute selection is based strictly on amplifier type, number of circuits, output type, slew rate, gain bandwidth product, supply current, input bias current, input offset voltage, supply voltage range, operating temperature range, mounting type, package/case, supplier device package, RoHS status, and MSL.

Q2: Are package and footprint considerations maintained among substitutes?
A2: Yes. All substitutes listed use the SC-74A, SOT-753 package and SOT-23-5 supplier device package, ensuring consistent mechanical compatibility.

Q3: Are there differences in environmental compliance among the listed substitutes?
A3: The original LM8261M5 is RoHS non-compliant and REACH affected. All substitute amplifiers listed are RoHS3 compliant and REACH unaffected.

Q4: Are there differences in performance parameters among the substitutes?
A4: While key functions such as amplifier type, circuit count, and package are matched, certain electrical parameters such as slew rate and gain bandwidth product may differ between the main part and certain substitutes. These differences are shown in the parameter comparison table.

Q5: Do all listed substitutes have the same operating temperature range?
A5: The substitute parts have an extended operating temperature range up to 125°C compared to the LM8261M5's maximum of 85°C. This ensures suitability for a broader range of applications within the specified parameters.

Q6: Can the LM8261M5X/NOPB be used as a direct replacement?
A6: The LM8261M5X/NOPB matches all primary parameters, including electrical performance, mechanical package, and is RoHS3 compliant. Product status is active.
