HA5023IPZ Equivalent & Substitute Parts

Part Overview

The HA5023IPZ is a dual-channel current feedback video amplifier manufactured by Renesas Electronics Corporation in a through-hole 8-DIP package. This linear amplifier is designed for video amplification applications requiring current feedback topology. The part is classified as obsolete, necessitating identification of equivalent substitute components for new designs or production continuity. Active alternatives with compatible electrical specifications and functional equivalence are available from both Renesas and third-party manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HA5023IPZ is determined by functional equivalence in the following critical parameters: dual-channel current feedback amplifier topology, number of circuits (2), -3dB bandwidth (125 MHz minimum), slew rate (350 V/µs minimum), supply current (7.5 mA nominal), output current per channel (20 mA minimum), and supply voltage range compatibility (±4.75V ~ 18V).

Two substitute parts meet these criteria:

HA5023IBZ (Renesas Electronics Corporation): Identical electrical specifications to the HA5023IPZ with the same base product number. Differs only in packaging format (8-SOIC surface mount versus 8-DIP through hole) and product status (active versus obsolete). Suitable for designs where surface-mount technology is acceptable.

LT1253CN8#PBF (Analog Devices Inc.): Functionally equivalent dual-channel current feedback amplifier in 8-DIP through-hole package. Exceeds minimum performance requirements with higher -3dB bandwidth (270 MHz), higher output current per channel (55 mA), and extended supply voltage range (4V ~ 28V, ±2V ~ 14V). Maintains through-hole mounting compatibility with the original HA5023IPZ.

Parameter Comparison

Engineering Selection Recommendations

For Direct Package Replacement (Through-Hole 8-DIP):

The LT1253CN8#PBF is the appropriate substitute when board layout and through-hole mounting compatibility are required. This part maintains identical package geometry (8-DIP, 0.300" pitch) and pinout compatibility with the HA5023IPZ. The LT1253CN8#PBF is an active product with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and environmental compliance. Performance specifications exceed the original part across bandwidth (270 MHz versus 125 MHz) and output current capability (55 mA versus 20 mA per channel), providing design margin for demanding video amplification applications.

For Surface-Mount Conversion:

The HA5023IBZ provides an alternative when transitioning to surface-mount technology is feasible. This part is manufactured by the same supplier as the original HA5023IPZ, ensuring identical electrical performance and functional behavior. The HA5023IBZ is an active product with full ROHS3 compliance and unlimited moisture sensitivity rating. The 8-SOIC package (0.154" width) requires PCB redesign but offers reduced board space and improved thermal characteristics compared to through-hole DIP packages.

Both substitute parts carry ROHS3 compliance and MSL 1 ratings, meeting environmental and reliability standards equivalent to the original HA5023IPZ.

Frequently Asked Questions (FAQ)

Q: Can the HA5023IBZ be used as a direct replacement for the HA5023IPZ on existing PCBs?

A: No. The HA5023IBZ uses an 8-SOIC surface-mount package, while the HA5023IPZ uses an 8-DIP through-hole package. These packages have different pinout footprints and require different PCB layouts. The HA5023IBZ is suitable only for new designs or PCBs redesigned for surface-mount components.

Q: Is the LT1253CN8#PBF a pin-for-pin replacement for the HA5023IPZ?

A: Yes. Both parts use the 8-DIP through-hole package with 0.300" (7.62mm) pitch. The LT1253CN8#PBF maintains pinout compatibility with the HA5023IPZ and can be substituted on existing PCBs without layout modifications.

Q: What are the key electrical differences between the HA5023IPZ and LT1253CN8#PBF?

A: The LT1253CN8#PBF provides higher -3dB bandwidth (270 MHz versus 125 MHz), higher output current per channel (55 mA versus 20 mA), and extended supply voltage range (4V ~ 28V single supply, ±2V ~ 14V dual supply versus ±4.75V ~ 18V). The LT1253CN8#PBF has slightly lower slew rate (250 V/µs versus 350 V/µs) and lower supply current (6 mA versus 7.5 mA).

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the HA5023IBZ and LT1253CN8#PBF are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings, matching the environmental compliance of the original HA5023IPZ.

Q: Which substitute part should be selected for new designs?

A: For new through-hole designs, the LT1253CN8#PBF is recommended due to its active product status, superior performance specifications, and extended supply voltage range. For new surface-mount designs, the HA5023IBZ is appropriate. Both parts ensure long-term availability and environmental compliance.

Q: What is the functional difference between current feedback and other amplifier topologies?

A: Current feedback amplifiers use transimpedance configuration, where feedback is applied to the inverting input through a transimpedance element. This topology provides advantages in bandwidth and slew rate performance compared to voltage feedback amplifiers, making it suitable for high-speed video amplification applications.

Q: Can the HA5023IPZ be sourced as a new component?

A: No. The HA5023IPZ is classified as obsolete. The HA5023IBZ (active status) or LT1253CN8#PBF (active status) must be used for new production or design continuity.
