Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by matching electrical and mechanical parameters relevant to the current sense amplifier category. The following key parameters must align for equivalency: amplifier type, number of circuits, output type, slew rate, gain bandwidth product, current input bias, input offset voltage, supply current and voltage span, operating temperature range, package/case, mounting type, RoHS and REACH compliance, moisture sensitivity level, and certification markings. Only part numbers with identical values in these parameters qualify as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection is based on the part status and compliance certifications. INA190A4IDDFT is listed as "Last Time Buy" while INA190A4IDDFR is "Active." Both parts are ROHS3 compliant, REACH unaffected, and share identical ECCN and HTSUS values. Moisture sensitivity level is identical at 1 (Unlimited). For ongoing designs and volume production, substitute selection should prioritize the "Active" status part when all compliance and certification parameters match.

Frequently Asked Questions (FAQ)

Q1: What parameters are mandatory for substituting INA190A4IDDFT in amplifier applications?
A1: All substitute parts must match amplifier type, number of circuits, output type, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, voltage supply span, operating temperature, mounting type, package/case, RoHS/REACH status, moisture sensitivity, ECCN, and HTSUS.

Q2: Is there a difference in package size or footprint between INA190A4IDDFT and INA190A4IDDFR?
A2: No. Both parts use SOT-23-8 case and TSOT-23-8 supplier device package, ensuring identical mechanical mounting.

Q3: How does the product status affect engineering decision-making for substitution?
A3: "Last Time Buy" status suggests pending discontinuation, while "Active" signifies ongoing production. For longevity and supply chain assurance, using an "Active" part with matching compliance and parameters is appropriate.

Q4: Are regulatory and supply chain compliance statuses aligned between these two parts?
A4: Yes. Both parts are ROHS3 compliant, REACH unaffected, moisture sensitivity level 1 (Unlimited), with identical ECCN and HTSUS codes.

Q5: Can INA190A4IDDFR be substituted for INA190A4IDDFT without electrical or mechanical compromise?
A5: Yes. All provided electrical and mechanical parameters are identical.
