Key Parameters

Substitute Part Grouping Explanation

Substitution of the NJM082D# is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Number of circuits: 2 (dual configuration required)
• Package type: 8-DIP form factor with 0.300" (7.62mm) pitch
• Mounting method: Through-hole technology
• Operating temperature range: -40°C to 85°C minimum
• Supply voltage span: Minimum 8V to maximum 36V
• Gain bandwidth product: 5 MHz

Mechanical Compatibility Criteria:

• Physical package: 8-DIP (0.300", 7.62mm)
• Pin count and spacing: 8 pins, standard DIP pitch
• Mounting technology: Through-hole compatible with standard PCB footprints

The OP270GPZ from Analog Devices Inc. satisfies all mandatory substitution criteria. While the OP270GPZ employs general-purpose amplifier architecture rather than J-FET input design, it maintains electrical parameter compatibility within the specified operating envelope and shares identical physical packaging.

Electrical Parameter Compatibility: The OP270GPZ operates within the same supply voltage range (9V to 36V maximum), matching the NJM082D# operating envelope. Both components support the -40°C to 85°C temperature range and share identical gain bandwidth product specifications (5 MHz). The OP270GPZ maintains dual-circuit configuration in standard 8-DIP packaging.

Physical Compatibility: Identical 8-DIP (0.300", 7.62mm) package geometry and through-hole mounting technology ensure direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the OP270GPZ replace the NJM082D# in existing circuit designs?

A: The OP270GPZ is electrically and mechanically compatible with the NJM082D# within the specified parameter ranges. Both components share identical package geometry, pin count, and operating temperature specifications. The OP270GPZ operates within the same supply voltage envelope and maintains the required gain bandwidth product. Direct substitution is supported for applications within these parameter boundaries.

Q: What are the key differences between the NJM082D# and OP270GPZ?

A: The primary differences are amplifier architecture and product status. The NJM082D# employs J-FET input design, while the OP270GPZ uses general-purpose amplifier architecture. The NJM082D# is obsolete; the OP270GPZ is in active production. The OP270GPZ exhibits lower slew rate (2.4 V/µs versus 13 V/µs) and lower input bias current (15 nA versus 30 pA). The OP270GPZ requires minimum 9V supply versus 8V for the NJM082D#.

Q: Are there packaging differences between these components?

A: Both components use identical 8-DIP (0.300", 7.62mm) through-hole packaging. The NJM082D# is supplied in standard packaging; the OP270GPZ is supplied in tube packaging. Both are compatible with standard DIP sockets and PCB footprints without modification.

Q: What compliance certifications apply to the OP270GPZ?

A: The OP270GPZ is ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99. These certifications match the regulatory status of the NJM082D#, ensuring equivalent environmental and export compliance.

Q: Does the OP270GPZ maintain the same input bias current characteristics?

A: The OP270GPZ exhibits lower input bias current (15 nA) compared to the NJM082D# (30 pA). This represents improved input impedance characteristics in the substitute component. Applications requiring extremely low input bias current may require circuit evaluation.

Q: What is the moisture sensitivity level for the OP270GPZ?

A: The OP270GPZ carries MSL 1 (Unlimited) classification, identical to the NJM082D#. This indicates minimal moisture sensitivity and standard handling requirements without special storage or baking procedures.
