LPV321M5 Equivalent & Substitute Parts Engineering Reference

Part Overview

The Texas Instruments LPV321M5 is a general purpose, rail-to-rail output, single-channel operational amplifier housed in a SOT-23-5 (SC-74A, SOT-753) package for surface mount applications. Key characteristics include low current consumption, a wide supply voltage span, low input bias, and a moderate gain bandwidth, making it suitable for low-power general signal amplification applications. The LPV321M5 has an Obsolete status. Due to this status, sourcing original parts is increasingly difficult, requiring the identification of functionally and mechanically compatible substitute models according to manufacturer-specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching all critical electrical and mechanical parameters provided. The allowed criteria for substitutions include amplifier type (general purpose), circuit count (1), output type (rail-to-rail), slew rate, gain bandwidth, input bias current, input offset voltage, supply current, maximum output current per channel, supply voltage range, operating temperature range, surface mount compatibility, package type (SC-74A, SOT-753, SOT-23-5), RoHS and REACH status, and MSL.

The following substitute parts meet these specified criteria according to the data provided.

Parameter Comparison

Engineering Selection Recommendations

The LPV321M5 is classified as Obsolete, while the substitute parts LPV321M5/NOPB, MCP6231RT-E/OT, MCP6231T-E/OT, and MCP6231UT-E/OT are listed as Active. All substitutes have RoHS3 compliance, which is an advancement over the RoHS non-compliant status of LPV321M5. All substitute models have an unlimited Moisture Sensitivity Level (MSL 1) and are REACH Unaffected. Substitutes should be considered on the basis of regulatory compliance, active product status, and equivalent mechanical compatibility within the constraints of the provided parameters.

Frequently Asked Questions (FAQ)

Q: What determines if a substitute operational amplifier is compatible with the LPV321M5?
A: Compatibility is determined by strict matching of amplifier type, number of circuits, output type, supply voltage range, slew rate, gain bandwidth, package (SC-74A, SOT-753, SOT-23-5), input bias current, input offset voltage, supply current, output current, operating temperature range, mounting type, and supplier device package.

Q: Do all listed substitutes fit directly into the same PCB footprint as the LPV321M5?
A: All listed substitutes use SC-74A, SOT-753 packages with SOT-23-5 footprints and are suitable for direct surface mount replacement.

Q: What is the difference in environmental compliance between LPV321M5 and its substitutes?
A: LPV321M5 is RoHS non-compliant. All substitutes (LPV321M5/NOPB, MCP6231RT-E/OT, MCP6231T-E/OT, MCP6231UT-E/OT) are RoHS3 compliant and REACH Unaffected.

Q: Why is it necessary to find substitutes for the LPV321M5?
A: The LPV321M5 is Obsolete, which may restrict supply continuity. Using active, compliant substitutes ensures ongoing procurement and consistent compliance with regulatory requirements.

Q: Are there differences in the maximum supply voltage or operating temperature between these substitute op amps?
A: Substitute parts have an extended supply voltage span (down to 1.8V, up to 6V) and broader operating temperature range (to 125°C) compared to the LPV321M5’s 2.7V–5V and -40°C~85°C.

Q: Do the substitutes meet the same mechanical and handling specifications?
A: All listed substitutes have a Moisture Sensitivity Level of 1 (Unlimited), matching the LPV321M5, and are suitable for surface mount installation within the same footprint.
