NE5534PSRG4 Equivalent & Substitute Parts

Part Overview

The NE5534PSRG4 is a general purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SO surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The NE5534PSRG4 serves as a single-circuit general purpose amplifier suitable for audio and instrumentation applications requiring moderate bandwidth and low input offset voltage. Due to its obsolete status, identifying compatible substitute components is essential for design continuity, procurement reliability, and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NE5534PSRG4 is determined by compatibility across the following critical parameters:

Functional Compatibility: The substitute must be a general purpose operational amplifier with a single circuit configuration, capable of operating within the supply voltage range of 10 V to 30 V minimum and maximum specifications.

Electrical Performance: Substitute parts must maintain input offset voltage at or below 500 µV to preserve circuit accuracy. Input bias current, slew rate, and gain bandwidth product may exceed the original specifications without causing functional degradation, as higher performance characteristics are backward compatible in general purpose amplifier applications.

Package Compatibility: The original NE5534PSRG4 uses an 8-SOIC package with 0.209" (5.30mm) width. Substitute parts must use equivalent 8-SOIC surface mount packages to ensure PCB layout compatibility and automated assembly feasibility.

Compliance & Status: Substitute parts must maintain ROHS3 compliance and active or current product status to ensure long-term availability and regulatory alignment.

The identified substitutes—AD847ARZ and AD847ARZ-REEL—meet all substitution criteria through superior electrical performance, active product status, and compatible packaging.

Parameter Comparison

Engineering Selection Recommendations

AD847ARZ and AD847ARZ-REEL Selection Basis:

Both AD847ARZ and AD847ARZ-REEL are active products manufactured by Analog Devices Inc., providing superior long-term availability compared to the obsolete NE5534PSRG4. Both substitutes maintain ROHS3 compliance and achieve lower moisture sensitivity levels (MSL 1 vs. MSL 2), reducing handling and storage risk.

The AD847ARZ and AD847ARZ-REEL are electrically compatible with the NE5534PSRG4 across all critical parameters. Input offset voltage remains at 500 µV, matching the original specification. Supply voltage ranges expand from 9 V to 36 V, encompassing the original 10 V to 30 V range. Operating temperature range extends to -40°C to 85°C, providing broader environmental coverage.

Packaging Consideration:

The substitute parts use 8-SOIC packages with reduced width (0.154", 3.90mm) compared to the original (0.209", 5.30mm). This dimensional difference requires PCB layout verification to confirm pad spacing compatibility. Pin count and functional pinout remain identical across all three parts.

Differentiation Between AD847ARZ and AD847ARZ-REEL:

AD847ARZ is supplied in tube packaging, while AD847ARZ-REEL is supplied on tape and reel. Both parts are electrically and functionally identical. Selection between these variants depends on procurement volume and assembly automation requirements.

Frequently Asked Questions (FAQ)

Q: Can AD847ARZ directly replace NE5534PSRG4 without circuit modification?

A: The AD847ARZ maintains functional compatibility through identical input offset voltage (500 µV), matching pin configuration, and compatible supply voltage range. However, the reduced package width (0.154" vs. 0.209") requires PCB layout verification to confirm pad spacing compatibility. No circuit modification is required if PCB layout accommodates the smaller package footprint.

Q: What is the difference between AD847ARZ and AD847ARZ-REEL?

A: Both parts are electrically and functionally identical. AD847ARZ is supplied in tube packaging for manual or semi-automated assembly. AD847ARZ-REEL is supplied on tape and reel for high-speed automated pick-and-place assembly. Selection depends on production volume and assembly equipment capabilities.

Q: Does the higher slew rate (300 V/µs vs. 13 V/µs) of the AD847ARZ affect circuit compatibility?

A: Higher slew rate is a performance enhancement that does not degrade compatibility. The AD847ARZ can switch faster than the original NE5534PSRG4, which is beneficial for transient response and signal fidelity. Existing circuit designs will function correctly with this improved characteristic.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: Both the NE5534PSRG4 and AD847ARZ/AD847ARZ-REEL are ROHS3 compliant and REACH unaffected. The substitute parts feature improved moisture sensitivity levels (MSL 1 with unlimited shelf life vs. MSL 2 with 1-year shelf life), reducing handling and storage requirements.

Q: Why is the NE5534PSRG4 classified as obsolete?

A: The NE5534PSRG4 has been discontinued by Texas Instruments. Obsolete status indicates that new production has ceased and existing inventory is limited. The AD847ARZ and AD847ARZ-REEL are active products with ongoing manufacturing support, ensuring long-term availability for new designs and production continuity.

Q: What is the impact of the expanded operating temperature range (-40°C to 85°C vs. 0°C to 70°C)?

A: The AD847ARZ operates across a broader temperature range, providing enhanced environmental coverage. Existing designs operating within the original 0°C to 70°C range will function identically. The expanded range enables use in more demanding thermal environments without performance degradation.
