Substitute Part Grouping Explanation

Substitution of the LMH6720MA is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the LMH6720MA/NOPB, which maintains identical electrical specifications including bandwidth, slew rate, supply current, output current, and supply voltage ranges. Both devices utilize the same 8-SOIC package footprint and surface mount configuration, ensuring mechanical compatibility at the board level.

The substitution logic is based on the following critical parameters:

• Identical -3dB bandwidth (400 MHz)
• Identical slew rate (1800V/µs)
• Identical supply current (5.6 mA)
• Identical output current per channel (70 mA)
• Identical supply voltage specifications (8V ~ 12.5V, ±4V ~ 6.25V)
• Identical package and case dimensions (8-SOIC, 0.154" width, 3.90mm)
• Identical mounting type (Surface Mount)
• Identical number of circuits (1)
• Same manufacturer (Texas Instruments)
• Same series designation (VIP10™)

Engineering Selection Recommendations

The LMH6720MA/NOPB is the direct substitute for the obsolete LMH6720MA. Both devices are electrically and mechanically identical across all specified parameters. The primary distinction between these parts is product status and regulatory compliance.

The LMH6720MA carries Obsolete status, indicating discontinued manufacturing and limited availability. The LMH6720MA/NOPB maintains Active product status, ensuring ongoing availability and supply chain support from Texas Instruments.

The LMH6720MA/NOPB achieves ROHS3 compliance, whereas the original LMH6720MA is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the LMH6720MA/NOPB is the appropriate selection. Both devices maintain REACH Unaffected status and EAR99 export classification.

The LMH6720MA/NOPB is supplied in Tube packaging, compared to the unspecified packaging of the original part. This packaging designation indicates standard tube format suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the LMH6720MA/NOPB be used as a direct replacement for the LMH6720MA?

A: Yes. The LMH6720MA/NOPB is a direct electrical and mechanical equivalent. All performance parameters, including bandwidth, slew rate, supply current, output current, and supply voltage specifications are identical. The 8-SOIC package footprint and pin configuration are unchanged, permitting direct substitution without circuit modification.

Q: What is the significance of the "/NOPB" suffix in the LMH6720MA/NOPB part number?

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) construction, reflecting RoHS3 compliance. This designation specifies the absence of lead in the solder and component materials, distinguishing it from the non-compliant original LMH6720MA.

Q: Are there packaging differences between the LMH6720MA and LMH6720MA/NOPB?

A: The LMH6720MA/NOPB is supplied in Tube packaging format. The original LMH6720MA packaging specification is not provided in the technical data. Both devices utilize the identical 8-SOIC physical package. Tube packaging is standard for surface mount components and is compatible with automated pick-and-place assembly equipment.

Q: Why is the LMH6720MA listed as Obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing of the LMH6720MA. The LMH6720MA/NOPB represents the current production equivalent, maintaining all electrical and mechanical specifications while incorporating modern RoHS3 compliance standards.

Q: Are there any supply voltage or current limitations that would prevent substitution?

A: No. Both devices operate across identical supply voltage ranges (8V ~ 12.5V single supply, ±4V ~ 6.25V dual supply) and draw identical supply current (5.6 mA). Output current capability per channel is identical at 70 mA. No circuit redesign is required for voltage or current compatibility.

Q: What is the moisture sensitivity level for these devices?

A: Both the LMH6720MA and LMH6720MA/NOPB carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. Standard handling and storage practices are sufficient for both devices.

Q: Are there any regulatory or compliance considerations for selecting between these parts?

A: The LMH6720MA/NOPB is ROHS3 compliant, whereas the LMH6720MA is RoHS non-compliant. For applications subject to RoHS directives or customer specifications requiring lead-free components, the LMH6720MA/NOPB is the required selection. Both devices maintain REACH Unaffected status and EAR99 export classification.
