Key Parameters

Substitute Part Grouping Explanation

Substitution for the HA5023IB is determined by strict alignment of electrical and mechanical parameters within the current feedback amplifier category. The primary substitution criteria are:

Critical Matching Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Number of Circuits: 2
• Amplifier Type: Current Feedback
• Voltage Supply Range: Compatibility with ±4.75V ~ 18V operation
• -3dB Bandwidth: Minimum 125 MHz
• Slew Rate: Minimum 350 V/µs
• Current Output / Channel: Minimum 20 mA

Direct Equivalent: The HA5023IBZ is the active production equivalent of the HA5023IB, sharing identical electrical specifications and package configuration while offering RoHS3 compliance and active product status.

Similar Substitutes: Parts from Analog Devices (AD8008 series), National Semiconductor (LMH6724 series), and Texas Instruments (THS3092D, THS3202D) meet the core package and topology requirements. These parts exceed the minimum bandwidth and slew rate specifications of the HA5023IB, providing enhanced performance headroom. Substitution feasibility depends on application-specific requirements for supply voltage range, output current capability, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Recommended for Obsolete Part Mitigation):

The HA5023IBZ is the primary recommended substitute for the HA5023IB. Both parts share identical electrical specifications, package configuration, and pin compatibility. The HA5023IBZ offers active product status and RoHS3 compliance, addressing the obsolescence and regulatory compliance limitations of the original HA5023IB. No circuit redesign is required for this substitution.

Performance-Enhanced Alternatives:

For applications where enhanced performance is acceptable, the following active parts provide superior specifications while maintaining 8-SOIC package compatibility:

• AD8008ARZ and AD8008ARZ-REEL7 (Analog Devices): Offer 500 MHz bandwidth and 1000 V/µs slew rate, exceeding HA5023IB specifications by 4× and 2.9× respectively. Supply voltage range is limited to 5V–12V, requiring circuit evaluation for compatibility with ±4.75V–18V applications.

• LMH6724MA/NOPB and LMH6724MAX/NOPB (National Semiconductor): Provide 370 MHz bandwidth and 600 V/µs slew rate with reduced supply current (1 mA per channel). Supply voltage range of 4.5V–12V is compatible with most HA5023IB applications.

• THS3092D (Texas Instruments): Delivers 160 MHz bandwidth and 5700 V/µs slew rate with extended supply voltage range (10V–30V). Suitable for high-voltage applications exceeding HA5023IB maximum ratings.

Parts Not Recommended for New Designs:

THS3202D carries "Not For New Designs" status and should not be selected for ongoing production or new applications despite superior performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the HA5023IBZ be used as a direct replacement for the HA5023IB?

A: Yes. The HA5023IBZ is electrically and mechanically identical to the HA5023IB. Both parts feature 125 MHz bandwidth, 350 V/µs slew rate, 8-SOIC packaging, and identical pin configuration. The HA5023IBZ is the active production equivalent and is recommended for all new procurement.

Q: What is the primary reason to substitute the HA5023IB?

A: The HA5023IB is classified as obsolete. The HA5023IBZ provides continuity with active product status and RoHS3 compliance. For new designs or applications requiring enhanced performance, the AD8008, LMH6724, or THS3092D series offer superior bandwidth and slew rate specifications.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All substitute parts listed are available in 8-SOIC (0.154", 3.90mm Width) surface mount packaging, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What are the key electrical differences between the HA5023IB and the AD8008ARZ?

A: The AD8008ARZ provides 500 MHz bandwidth (versus 125 MHz) and 1000 V/µs slew rate (versus 350 V/µs), representing 4× and 2.9× performance improvements respectively. However, the AD8008ARZ supply voltage range is limited to 5V–12V, compared to the HA5023IB range of ±4.75V–18V. Circuit evaluation is required for applications operating outside the 5V–12V window.

Q: Can the LMH6724 series be used in place of the HA5023IB?

A: The LMH6724MA/NOPB and LMH6724MAX/NOPB are functionally compatible substitutes. Both provide 370 MHz bandwidth and 600 V/µs slew rate in 8-SOIC packaging. The supply voltage range of 4.5V–12V is compatible with most HA5023IB applications. Supply current is significantly lower (1 mA per channel versus 7.5 mA), which may reduce thermal dissipation in power-sensitive designs.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: The HA5023IB is RoHS non-compliant. Most substitute parts, including HA5023IBZ, AD8008ARZ, and THS3092D, are RoHS3 compliant. RoHS compliance is mandatory for products sold in the European Union and increasingly required by global OEMs. Selection of RoHS-compliant substitutes ensures regulatory compliance and supply chain continuity.

Q: Is the THS3202D suitable for new designs?

A: No. The THS3202D carries "Not For New Designs" status. While it offers exceptional performance (2 GHz bandwidth, 9000 V/µs slew rate), it should not be selected for ongoing production or new applications. The THS3092D is the recommended Texas Instruments alternative for new designs.

Q: How do I determine which substitute is appropriate for my application?

A: Evaluate your application requirements against the following parameters: required bandwidth, slew rate, supply voltage range, output current capability, and compliance certifications. The HA5023IBZ is the direct replacement. For enhanced performance, compare your bandwidth and slew rate requirements against the AD8008, LMH6724, and THS3092D specifications. Verify that the substitute's supply voltage range accommodates your circuit design.

Q: Are there packaging format differences among the substitute parts?

A: Yes. Packaging formats vary: HA5023IBZ is supplied in Tube; AD8008ARZ in Tube; AD8008ARZ-REEL7 in Tape & Reel; LMH6724MA/NOPB and LMH6724MAX/NOPB in Bulk; THS3092D and THS3202D in Tube. All use identical 8-SOIC case dimensions. Packaging selection affects procurement, handling, and assembly processes but does not impact electrical performance or PCB compatibility.
