Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NJM072D are selected strictly based on the following key parameters: amplifier type, number of circuits, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, supply voltage range, operating temperature range, mounting type, package/case format, and compliance (RoHS, REACH, ECCN, HTSUS). All alternative models meet or closely align with these criteria while offering compatible packaging and certification. Substitute parts must maintain functional and dimensional compatibility in existing designs adhering to the provided electrical and regulatory parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts—OP270GPZ, OP275GPZ, and TL3472IP—are active and maintain compliance with RoHS, REACH, and ECCN/HTSUS requirements as specified. Their through-hole 8-DIP (0.300", 7.62mm) packaging matches the original NJM072D mechanical format. The operating temperature ranges, supply voltages, and other regulatory certifications align with the original IC’s standards.

Frequently Asked Questions (FAQ)

Q1: What are the criteria for substituting the NJM072D in existing designs?
A1: Substitute components are chosen based on alignment with amplifier type, circuit count, slew rate, gain bandwidth, input bias current, supply voltage range, operating temperature, compliance certifications, mounting type, and package dimensions.

Q2: Are substitute parts mechanically compatible with NJM072D?
A2: All listed substitutes use the 8-DIP (0.300", 7.62mm) through-hole package, ensuring compatibility for board-level replacement.

Q3: Do substitute parts have certified environmental and export compliance?
A3: Substitute amplifiers are RoHS Compliant (ROHS3) and REACH Unaffected, with the same ECCN (EAR99) and HTSUS code (8542.33.0001) as the original NJM072D.

Q4: Are operating temperature ranges maintained with substitutes?
A4: All substitutes provide an operating temperature range of at least -40°C ~ 85°C or better per the supplied specifications.

Q5: Which electrical parameters should be verified for form-fit substitution?
A5: Engineering consideration is strictly limited to amplifier type, number of circuits, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, voltage supply span, and package type—per the table above.
