Key Parameters

Substitute Part Grouping Explanation

Substitution for LM7321MFE/NOPB is governed strictly by matching on critical electrical and mechanical parameters. Key parameters ensuring interchangeability include: manufacturer, amplifier type, number of circuits, output type, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, voltage supply range, operating temperature, mounting type, package/case, supplier device package, RoHS and REACH compliance, MSL, and export/HTSUS classification.

Parameter Comparison

Engineering Selection Recommendations

Selection is based on the product status and compliance certifications. LM7321MFE/NOPB is obsolete, while LM7321MFX/NOPB is active. Both are ROHS3 compliant, REACH unaffected, and have MSL 1 rating. Both parts share identical electrical, mechanical, and compliance parameters according to the provided data.

Frequently Asked Questions (FAQ)

Q1: What parameters determine a valid substitute for LM7321MFE/NOPB?
A1: A valid substitute must match on amplifier type, number of circuits, output type, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, voltage supply range, operating temperature range, mounting type, package/case, supplier device package, RoHS and REACH status, MSL, and export/HTSUS classification.

Q2: Is LM7321MFX/NOPB a direct substitute for LM7321MFE/NOPB?
A2: Yes. LM7321MFX/NOPB matches all specified electrical, mechanical, and compliance parameters of LM7321MFE/NOPB.

Q3: Does the packaging format affect substitute selection?
A3: Packaging format (Cut Tape, Digi-Reel®) relates to handling and supply chain preferences but does not affect electrical or mechanical substitution criteria as long as the package/case and supplier device package (e.g., SOT-23-5) are identical.

Q4: Are there differences in environmental or compliance certifications between the main and substitute parts?
A4: Both parts are ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited) status.

Q5: What is the primary factor for needing a substitute part?
A5: The primary factor is the obsolete status of LM7321MFE/NOPB, requiring sourcing of an active part with identical parameters such as LM7321MFX/NOPB.
