NJM072BD Equivalent & Substitute Parts Reference

Part Overview

The NJM072BD is a J-FET input operational amplifier IC, featuring two amplifier circuits in an 8-DIP (0.300", 7.62mm) through-hole package. Manufactured by Nisshinbo Micro Devices Inc., it is classified under Linear, Amplifiers. The part is currently obsolete. For continued manufacturing, repair, and sourcing purposes, it is necessary to identify alternative models that match the NJM072BD's key electrical, mechanical, and compliance parameters.

Key Parameters

Substitute Part Grouping Explanation

Selection of substitute parts for the NJM072BD is based strictly on matching 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, and package / case dimensions. Only parts matching these parameters for electrical, mechanical, and regulatory compliance are included as substitutes.

Key substitution parameters:

• Amplifier Type
• Number of Circuits
• Slew Rate
• Gain Bandwidth Product
• Current - Input Bias
• Voltage - Input Offset
• Current - Supply
• Voltage - Supply Span (Min and Max)
• Operating Temperature
• Mounting Type
• Package / Case
• RoHS and REACH Status

Parameter Comparison

Engineering Selection Recommendations

The NJM072BD is designated as obsolete. Substitute parts LF353P and OP270GPZ are classified as active and meet RoHS and REACH compliance criteria. The LF353P matches the amplifier type (J-FET) and shares most electrical and mechanical parameters with the NJM072BD. The OP270GPZ, while having a general-purpose amplifier type, maintains two amplifier circuits and compatible pinout and package. Selection should be based on current product status and regulatory compliance information provided.

Frequently Asked Questions (FAQ)

Q: What determines whether a substitute operational amplifier is suitable for replacing the NJM072BD?
A: Suitability is defined by matching key parameters: amplifier type, number of circuits, slew rate, gain bandwidth product, input bias current, voltage input offset, supply current, supply voltage range, operating temperature range, mounting type, package dimensions, and regulatory compliance.

Q: Are the pinouts and package of LF353P and OP270GPZ identical to those of NJM072BD?
A: Both LF353P and OP270GPZ use the 8-DIP (0.300", 7.62mm) through-hole package, matching the NJM072BD package and footprint.

Q: Can the operational temperature range affect drop-in compatibility?
A: Yes. NJM072BD and OP270GPZ both support -40°C ~ 85°C. The LF353P specifies 0°C ~ 70°C.

Q: How does RoHS or REACH compliance impact the selection process?
A: Only parts with clear RoHS and REACH accepted status are listed to meet regulatory and environmental requirements.

Q: Which parameter differences should be noted when substituting OP270GPZ for NJM072BD?
A: The OP270GPZ is classified as a general-purpose amplifier, offers a gain bandwidth product of 5 MHz, and a slew rate of 2.4V/µs, differing from the J-FET amplifier and 13V/µs slew rate of NJM072BD.
