LMH6624MA Equivalent & Substitute Parts

Part Overview

The LMH6624MA is a voltage feedback amplifier integrated circuit manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as a Last Time Buy product, indicating discontinued production with limited inventory availability. The LMH6624MA delivers high-speed amplification with a 1.5 GHz gain bandwidth product and 400V/µs slew rate, suitable for applications requiring wideband signal conditioning and high-frequency amplification.

Due to Last Time Buy status and finite stock levels (6365 pcs), identifying equivalent substitute parts ensures design continuity and supply chain reliability for new production runs and long-term product support.

Engineering Selection Recommendations

LMH6624MAX/NOPB is the primary recommended substitute for the LMH6624MA. This part is manufactured by Texas Instruments (original manufacturer), maintains Active product status, and carries ROHS3 compliance certification. The LMH6624MAX/NOPB is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume production environments. All electrical and mechanical parameters are identical to the LMH6624MA. The primary distinction is packaging format: Tube versus Tape & Reel. This substitute is suitable for direct replacement in new production designs and ongoing manufacturing.

LMH6624MA/NOPB is a secondary parametric equivalent manufactured by National Semiconductor. This part maintains identical electrical specifications and mechanical compatibility. The product status is Active, ensuring continued availability. Packaging format and RoHS/MSL certifications are not specified in available documentation. This substitute is electrically equivalent but requires verification of packaging compatibility and compliance requirements for specific applications.

Selection between LMH6624MAX/NOPB and LMH6624MA/NOPB depends on packaging requirements and supply chain preferences. For applications requiring Tape & Reel format and confirmed ROHS3 compliance, LMH6624MAX/NOPB is the preferred choice. Both substitutes provide identical electrical performance and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can LMH6624MAX/NOPB be used as a direct replacement for LMH6624MA in existing designs?

A: Yes. The LMH6624MAX/NOPB is electrically and mechanically equivalent to the LMH6624MA. All performance parameters, including slew rate, gain bandwidth product, input bias current, and supply voltage range, are identical. The primary difference is packaging format (Tape & Reel versus Tube). PCB layout and schematic connections remain unchanged.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for lower-volume applications and manual assembly processes. Tape & Reel (TR) packaging is standard for automated pick-and-place assembly in high-volume production. Both formats contain the same die and provide identical electrical performance. Selection depends on manufacturing process requirements and assembly equipment compatibility.

Q: Is LMH6624MA/NOPB from National Semiconductor fully compatible with the Texas Instruments LMH6624MA?

A: LMH6624MA/NOPB maintains identical electrical specifications and mechanical package dimensions. However, RoHS compliance status and Moisture Sensitivity Level are not specified in available documentation. Verification of compliance certifications is required before use in applications with specific regulatory or environmental requirements.

Q: Why is the LMH6624MA classified as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. Existing inventory is available for a limited time. Customers requiring this device for ongoing production should transition to active substitute parts such as LMH6624MAX/NOPB to ensure long-term supply continuity.

Q: Are there any thermal or frequency response differences between the substitute parts?

A: No. All substitute parts maintain identical operating temperature range (-40°C to 125°C), gain bandwidth product (1.5 GHz), and -3dB bandwidth (95 MHz). Thermal performance and frequency response characteristics are equivalent across all listed parts.

Q: Can these parts be used interchangeably in high-frequency applications above 95 MHz?

A: The -3dB bandwidth specification is 95 MHz for all listed parts. Applications requiring operation above this frequency must be evaluated against specific gain and phase margin requirements. The 1.5 GHz gain bandwidth product indicates the device can operate at higher frequencies with reduced closed-loop gain. Circuit design and stability analysis determine maximum usable frequency for specific applications.
