LMH6720MF Equivalent & Substitute Parts

Part Overview

The LMH6720MF is a current feedback video amplifier integrated circuit manufactured by Texas Instruments, housed in a SOT-23-6 surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability through standard distribution channels. The LMH6720MF operates as a single-channel linear amplifier with -3dB bandwidth of 400 MHz and slew rate of 1800V/µs, designed for current feedback applications requiring high-speed signal processing.

Due to its obsolete status, sourcing original LMH6720MF units presents supply chain challenges. Direct manufacturer equivalents with active production status are available to ensure design continuity and long-term component availability.

Engineering Selection Recommendations

The LMH6720MF/NOPB is the direct equivalent substitute for the obsolete LMH6720MF. Selection of the LMH6720MF/NOPB is based on the following engineering factors:

Product Status: The LMH6720MF/NOPB maintains active production status with Texas Instruments, ensuring long-term availability and supply chain reliability compared to the obsolete LMH6720MF.

Electrical Equivalence: All electrical parameters are identical between the main part and substitute, including bandwidth, slew rate, supply current, output current, and supply voltage ranges. Direct functional substitution is supported without circuit modification.

Mechanical Compatibility: Both parts utilize identical SOT-23-6 surface mount packaging and mounting type, enabling direct PCB layout compatibility without redesign.

Compliance Enhancement: The LMH6720MF/NOPB achieves ROHS3 compliance, whereas the LMH6720MF is RoHS non-compliant. This improvement aligns with current regulatory requirements for electronic components in regulated markets.

Packaging Format: The LMH6720MF/NOPB is supplied in Tape & Reel (TR) format, standard for automated assembly operations, compared to bulk packaging of the original part. This format is compatible with standard pick-and-place equipment used in manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the LMH6720MF/NOPB be used as a direct replacement for the LMH6720MF?

A: Yes. The LMH6720MF/NOPB is a direct equivalent substitute. All electrical parameters, including -3dB bandwidth (400 MHz), slew rate (1800V/µs), supply current (5.6 mA), output current (70 mA), and supply voltage ranges (8V ~ 12.5V, ±4V ~ 6.25V) are identical. The mechanical package (SOT-23-6) and mounting type (Surface Mount) are also identical, enabling direct substitution without circuit modification or PCB redesign.

Q: What is the difference between LMH6720MF and LMH6720MF/NOPB?

A: The primary differences are product status, RoHS compliance, and packaging format. The LMH6720MF is obsolete with RoHS non-compliant status and bulk packaging. The LMH6720MF/NOPB is actively produced, ROHS3 compliant, and supplied in Tape & Reel format. All electrical and mechanical specifications are identical.

Q: Why is the LMH6720MF marked as obsolete?

A: The LMH6720MF has been discontinued by Texas Instruments. The LMH6720MF/NOPB represents the active production equivalent, ensuring continued availability for new designs and component replenishment.

Q: Is the Tape & Reel packaging of the LMH6720MF/NOPB compatible with automated assembly?

A: Yes. Tape & Reel (TR) packaging is the standard format for automated pick-and-place assembly equipment used in manufacturing environments. This format is compatible with standard component feeders and placement machines.

Q: Are there any circuit design changes required when substituting LMH6720MF with LMH6720MF/NOPB?

A: No. Since all electrical parameters and the mechanical package are identical, no circuit design changes are required. The substitute part functions identically in the same application circuit.

Q: What is the significance of ROHS3 compliance on the LMH6720MF/NOPB?

A: ROHS3 compliance indicates the part meets current Restriction of Hazardous Substances regulations, restricting the use of specific hazardous materials in electrical and electronic equipment. This compliance is required for products sold in regulated markets and demonstrates adherence to environmental and safety standards.

Q: Can the LMH6720MF/NOPB be used in existing designs originally specified for LMH6720MF?

A: Yes. The LMH6720MF/NOPB is functionally and mechanically equivalent to the LMH6720MF. Existing designs require no modification for component substitution. PCB layouts, schematic connections, and circuit operation remain unchanged.
