HA3-2625-5 Equivalent & Substitute Parts

Part Overview

The HA3-2625-5 is a general-purpose operational amplifier manufactured by Renesas Electronics Corporation in an 8-DIP through-hole package. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The part operates across a 10V to 40V supply range with a slew rate of 35V/µs and gain bandwidth product of 100 MHz, suitable for general-purpose amplification applications requiring moderate to high-speed performance.

Due to its obsolete status, equivalent and substitute parts are necessary for ongoing system support, design continuity, and component procurement. Active alternatives with comparable electrical characteristics and identical packaging are available from both Renesas Electronics and Texas Instruments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA3-2625-5 is determined by the following criteria:

Mechanical Compatibility: All substitute parts must use identical 8-DIP through-hole packaging (0.300", 7.62mm) to ensure direct socket compatibility without PCB redesign.

Electrical Compatibility: Substitute parts must operate within the supply voltage range of 10V to 40V and maintain general-purpose amplifier functionality. Input bias current, input offset voltage, slew rate, and gain bandwidth product are secondary parameters that may vary within acceptable application tolerances.

Functional Equivalence: All candidates are single-circuit general-purpose operational amplifiers in 8-PDIP configuration, confirming functional equivalence at the circuit topology level.

The substitute parts are grouped into two categories:

1. Direct Renesas Equivalent (HA3-2525-5Z): Same manufacturer, identical package, active product status with RoHS3 compliance.

2. Cross-Manufacturer Alternatives (LM318N/NOPB, LM318P): Texas Instruments equivalents with identical packaging and active product status, offering broader supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

For Renesas-Based Supply Chains:

The HA3-2525-5Z is the primary substitute for the obsolete HA3-2625-5 within the Renesas product family. Both parts share identical packaging, mounting type, and operating temperature range (0°C to 75°C). The HA3-2525-5Z maintains active product status and RoHS3 compliance, supporting modern procurement and environmental regulations. The HA3-2525-5Z operates within the minimum supply voltage of 8V, providing broader supply flexibility than the HA3-2625-5 (10V minimum). This part is suitable for direct replacement in existing designs.

For Cross-Manufacturer Flexibility:

The LM318N/NOPB and LM318P from Texas Instruments provide alternative sources for the 8-DIP general-purpose amplifier function. Both parts are active products with RoHS3 compliance and support the full 10V to 40V supply range of the original HA3-2625-5. The LM318 series exhibits lower gain bandwidth product (15 MHz versus 100 MHz) and reduced slew rate (70V/µs versus 35V/µs), making these parts suitable for applications where the original performance specifications exceed system requirements. Operating temperature range is limited to 0°C to 70°C, which is acceptable for most industrial and commercial applications.

Compliance Considerations:

All active substitute parts (HA3-2525-5Z, LM318N/NOPB, LM318P) are RoHS3 compliant, addressing environmental and regulatory requirements that the obsolete HA3-2625-5 does not meet. REACH status is unaffected for all parts.

Frequently Asked Questions (FAQ)

Q: Can the HA3-2525-5Z directly replace the HA3-2625-5 in existing PCB designs?

A: Yes. Both parts use identical 8-DIP through-hole packaging (0.300", 7.62mm) and can be installed in the same socket without PCB modification. Pin configuration and functional operation are compatible.

Q: What are the key electrical differences between the HA3-2625-5 and HA3-2525-5Z?

A: The HA3-2525-5Z exhibits higher slew rate (120V/µs versus 35V/µs) and lower gain bandwidth product (20 MHz versus 100 MHz). Input bias current is higher (125 nA versus 5 nA), and input offset voltage is slightly higher (5 mV versus 3 mV). The HA3-2525-5Z operates at a lower minimum supply voltage (8V versus 10V). These differences are acceptable for general-purpose amplifier applications where the original specifications are not critical design constraints.

Q: Are the Texas Instruments LM318 parts suitable replacements?

A: The LM318N/NOPB and LM318P are suitable for applications where the lower gain bandwidth product (15 MHz) and slew rate (70V/µs) meet system requirements. Both parts support the 10V to 40V supply range and are available in identical 8-DIP packaging. Operating temperature range is limited to 0°C to 70°C, which is 5°C lower than the original part. These parts are appropriate for general-purpose amplification where high-speed performance is not required.

Q: What is the difference between LM318N/NOPB and LM318P?

A: Both parts are functionally equivalent with identical electrical specifications. The primary difference is packaging designation: LM318N/NOPB indicates a tube package format, while LM318P also uses tube packaging. Both are suitable for through-hole PCB assembly. Inventory availability differs, with LM318P showing higher stock levels (14,329 units versus 4,036 units).

Q: Does the HA3-2525-5Z meet modern environmental compliance requirements?

A: Yes. The HA3-2525-5Z is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The obsolete HA3-2625-5 is RoHS non-compliant and should be replaced in new designs to ensure regulatory compliance.

Q: What supply voltage range should I use for each substitute part?

A: The HA3-2625-5 and LM318 series (LM318N/NOPB, LM318P) operate across 10V to 40V. The HA3-2525-5Z operates across 8V to 36V. All parts are compatible with standard ±5V, ±12V, and ±15V dual-supply configurations within these ranges.

Q: Are there any temperature range limitations I should consider?

A: The HA3-2625-5 and HA3-2525-5Z both operate across 0°C to 75°C. The LM318N/NOPB and LM318P are limited to 0°C to 70°C. For applications requiring operation above 70°C, the HA3-2525-5Z is the appropriate choice.
