HA5023IP Equivalent & Substitute Parts

Part Overview

The HA5023IP is a dual-channel current feedback amplifier manufactured by Renesas Electronics Corporation, designed for video amplification applications. This device operates with a -3dB bandwidth of 125 MHz and a slew rate of 350V/µs, packaged in an 8-DIP through-hole configuration. The HA5023IP is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HA5023IP is determined by compatibility across the following critical parameters:

Package and Pinout Compatibility: Both the main part and substitute must utilize the 8-DIP (0.300", 7.62mm) through-hole package to ensure mechanical and electrical compatibility with existing PCB layouts.

Functional Architecture: The substitute must provide dual-channel current feedback amplification topology, maintaining the same number of circuits (2) as the original device.

Electrical Operating Range: The substitute must support the voltage supply range required by the application. The HA5023IP operates at ±4.75V ~ 18V, and the substitute must accommodate this range or provide a compatible superset.

Performance Characteristics: While the substitute may exceed the original specifications in bandwidth and slew rate, it must not fall below the minimum performance requirements of the application. The substitute must deliver current feedback amplification suitable for video signal processing.

Compliance and Availability: Given the obsolete status of the HA5023IP, active product alternatives with modern compliance certifications (RoHS3, REACH) are prioritized to support long-term system reliability and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The LT1253CN8#PBF from Analog Devices Inc. is a direct functional substitute for the HA5023IP. Both devices share identical package geometry (8-DIP), circuit count (2 channels), and application classification (current feedback amplifiers for video processing).

Compatibility Assessment: The LT1253CN8#PBF operates within a broader voltage supply range (4V ~ 28V single supply, ±2V ~ 14V dual supply) that encompasses the HA5023IP operating range of ±4.75V ~ 18V. The substitute provides enhanced bandwidth performance (270 MHz versus 125 MHz) and increased output current capability (55 mA per channel versus 20 mA), while maintaining lower supply current consumption (6 mA versus 7.5 mA).

Product Status Advantage: The LT1253CN8#PBF is classified as active, ensuring continued availability and manufacturing support. This contrasts with the obsolete status of the HA5023IP, which presents long-term supply chain risk.

Regulatory Compliance: The LT1253CN8#PBF meets ROHS3 compliance requirements, whereas the HA5023IP is RoHS non-compliant. For applications subject to modern regulatory frameworks, the LT1253CN8#PBF provides compliance alignment.

Performance Trade-offs: The LT1253CN8#PBF exhibits a lower slew rate (250V/µs versus 350V/µs). Applications requiring the maximum slew rate specification of the HA5023IP must evaluate whether the 250V/µs performance of the substitute meets system requirements.

Frequently Asked Questions (FAQ)

Q: Can the LT1253CN8#PBF directly replace the HA5023IP in existing designs?

A: The LT1253CN8#PBF shares the same 8-DIP package footprint and pinout as the HA5023IP, enabling direct mechanical and electrical substitution. Both devices provide dual-channel current feedback amplification. However, the slew rate specification differs (250V/µs versus 350V/µs), requiring verification that the application does not depend on the higher slew rate of the original device.

Q: What are the key differences in electrical performance?

A: The LT1253CN8#PBF provides superior bandwidth (270 MHz versus 125 MHz) and higher output current per channel (55 mA versus 20 mA). The substitute operates at lower supply current (6 mA versus 7.5 mA) and supports a wider voltage supply range. The primary performance trade-off is reduced slew rate (250V/µs versus 350V/µs).

Q: Are there packaging differences between these devices?

A: Both the HA5023IP and LT1253CN8#PBF utilize identical 8-DIP (0.300", 7.62mm) through-hole packaging. No PCB layout modifications are required for substitution.

Q: What is the supply voltage compatibility?

A: The HA5023IP operates at ±4.75V ~ 18V. The LT1253CN8#PBF supports 4V ~ 28V single supply or ±2V ~ 14V dual supply operation. The substitute voltage range encompasses the original device specifications, ensuring compatibility across all standard operating conditions.

Q: Does the LT1253CN8#PBF meet modern compliance standards?

A: The LT1253CN8#PBF is ROHS3 compliant and REACH unaffected. The HA5023IP is RoHS non-compliant. For applications requiring regulatory compliance with modern environmental standards, the LT1253CN8#PBF is the appropriate selection.

Q: Why is the HA5023IP classified as obsolete?

A: The HA5023IP is no longer in active production by Renesas Electronics Corporation. The LT1253CN8#PBF from Analog Devices Inc. remains in active production, providing assured long-term availability for new designs and system support.

Q: What applications are these devices suitable for?

A: Both devices are designed for current feedback amplification in video signal processing applications, where high bandwidth and fast slew rate performance are required for accurate signal conditioning and amplification.
