HA3-2525-5Z Equivalent & Substitute Parts

Part Overview

The HA3-2525-5Z is a general purpose operational amplifier manufactured by Renesas Electronics Corporation, housed in an 8-DIP through-hole package. This linear amplifier integrated circuit contains a single amplification circuit and is classified as an active product with full RoHS3 compliance. The device operates across a supply voltage range of 8V to 36V and is suitable for general purpose amplification applications requiring moderate bandwidth and slew rate performance.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from multiple qualified manufacturers. The HA3-2525-5Z has been identified with one direct substitute that maintains functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA3-2525-5Z is determined by strict alignment across the following critical parameters:

Package and Mounting Compatibility: Both the main part and substitute must utilize the 8-DIP through-hole package format with identical physical dimensions (0.300", 7.62mm) to ensure direct printed circuit board compatibility without layout modifications.

Functional Classification: The substitute must be classified as a general purpose operational amplifier with a single amplification circuit to maintain functional equivalence within the application context.

Electrical Performance Envelope: The substitute must operate within the established supply voltage range (minimum 8V, maximum 36V) and maintain compatibility with the input and output current specifications of the primary device.

Regulatory and Compliance Status: Both parts must maintain active product status and RoHS3 compliance to satisfy current procurement and environmental standards.

The LM318P from Texas Instruments meets these substitution criteria across all mandatory parameters while operating within the defined electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The HA3-2525-5Z remains the preferred selection when available, as it is an active product with full RoHS3 compliance and REACH unaffected status. Current inventory of 1590 pieces supports immediate procurement.

Substitute Part Selection: The LM318P is qualified as a direct substitute when the HA3-2525-5Z is unavailable. The LM318P is an active product with equivalent RoHS3 compliance and REACH unaffected status. Inventory availability of 14329 pieces provides extended supply security.

Compliance Verification: Both parts carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, confirming regulatory equivalence for export and tariff purposes.

Thermal Operating Range Consideration: The HA3-2525-5Z supports operation to 75°C, while the LM318P operates to 70°C maximum. Applications requiring operation above 70°C must retain the HA3-2525-5Z.

Supply Voltage Range Consideration: The HA3-2525-5Z operates from 8V minimum, while the LM318P requires 10V minimum. Applications operating below 10V supply voltage must retain the HA3-2525-5Z.

Frequently Asked Questions (FAQ)

Q: Can the LM318P be used as a direct replacement for the HA3-2525-5Z without circuit modifications?

A: The LM318P is mechanically and functionally compatible with the HA3-2525-5Z in the 8-DIP package format. However, the LM318P has a higher minimum supply voltage requirement (10V versus 8V) and a lower maximum operating temperature (70°C versus 75°C). Circuit modifications are not required if the application operates within the LM318P's specified envelope.

Q: What are the key electrical differences between these two parts?

A: The HA3-2525-5Z provides superior slew rate performance (120V/µs versus 70V/µs) and higher gain bandwidth product (20MHz versus 15MHz). The LM318P exhibits lower input offset voltage (4mV versus 5mV) and slightly lower input bias current (150nA versus 125nA). These differences are within typical general purpose amplifier performance variation.

Q: Are both parts suitable for high-temperature applications?

A: The HA3-2525-5Z supports continuous operation to 75°C. The LM318P is rated to 70°C maximum. For applications requiring operation above 70°C, the HA3-2525-5Z is the appropriate selection.

Q: Do both parts require identical printed circuit board footprints?

A: Yes. Both the HA3-2525-5Z and LM318P utilize the 8-DIP package with 0.300" (7.62mm) spacing, requiring identical through-hole footprints. No PCB layout modifications are necessary for substitution.

Q: What is the minimum supply voltage for each part?

A: The HA3-2525-5Z operates from 8V minimum supply voltage. The LM318P requires 10V minimum. Applications using supply voltages between 8V and 10V must use the HA3-2525-5Z.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the HA3-2525-5Z and LM318P carry full RoHS3 compliance certification and are REACH unaffected, meeting current environmental and regulatory requirements.
