Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete LMV321IST5 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must maintain identical specifications for amplifier type, circuit count, output configuration, frequency response, bias characteristics, supply current, output drive capability, supply voltage range, and operating temperature envelope. Package compatibility requires surface mount TSOT-23-5 form factor with matching pin configuration and moisture sensitivity classification. The LMV321SN3T1G from onsemi satisfies all these criteria while maintaining active product status and full compliance with applicable regulatory standards.
