Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMH6732MA is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier topology (Current Feedback architecture)
• Slew rate (2700 V/µs)
• Bandwidth (-3dB at 540 MHz)
• Input bias current (2 µA)
• Input offset voltage (3 mV)
• Supply current (9 mA)
• Output current per channel (115 mA)
• Supply voltage range (9 V to 12 V)
• Operating temperature range (-40°C to 85°C)

Mechanical & Package Criteria:

• Package type (8-SOIC)
• Physical dimensions (0.154" width, 3.90mm)
• Mounting technology (Surface Mount)

Only parts matching all electrical and mechanical parameters are classified as direct substitutes. Variations in packaging format (such as tube versus alternative packaging) do not affect functional equivalence when the core package type remains identical.

Engineering Selection Recommendations

LMH6732MA/NOPB is the direct functional equivalent and substitute for the obsolete LMH6732MA. Both parts are manufactured by Texas Instruments and maintain identical electrical performance specifications across all measured parameters.

The primary distinction between these parts is product status and regulatory compliance:

The LMH6732MA carries obsolete status, indicating discontinued manufacturing and limited availability. The LMH6732MA/NOPB maintains active product status with current manufacturing support from Texas Instruments.

The LMH6732MA/NOPB achieves ROHS3 compliance, whereas the original LMH6732MA is RoHS non-compliant. This distinction is significant for applications subject to regulatory requirements mandating RoHS compliance in electronic components.

Both parts share identical moisture sensitivity classification (MSL 1 - Unlimited) and REACH status (REACH Unaffected), indicating equivalent handling and environmental compliance characteristics.

For new designs or ongoing production requiring this amplifier topology, the LMH6732MA/NOPB is the appropriate selection, offering continued manufacturer support and regulatory compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can the LMH6732MA/NOPB directly replace the LMH6732MA in existing designs?

A: Yes. The LMH6732MA/NOPB is electrically and mechanically identical to the LMH6732MA. All electrical parameters, package dimensions, and mounting specifications are equivalent. No circuit modifications are required for substitution.

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

A: The "/NOPB" designation indicates "No Plumbum" (lead-free) packaging format. This reflects the RoHS3 compliance status of the part. The electrical performance and functionality remain unchanged compared to the base part number.

Q: Why is the LMH6732MA listed as obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing of this specific part number variant. The LMH6732MA/NOPB represents the current production equivalent, incorporating modern compliance standards.

Q: Are there any differences in the 8-SOIC package between these parts?

A: No. Both parts utilize the identical 8-SOIC package with 0.154" width and 3.90mm physical dimensions. Surface mount assembly processes and PCB footprints are directly compatible.

Q: What is the inventory status for these parts?

A: The LMH6732MA shows 1552 pieces in stock as new original inventory. The LMH6732MA/NOPB shows 2074 pieces in stock as new original inventory. Availability may vary based on current supply conditions.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical amplifier characteristics and specifications.

Q: Can these parts be used interchangeably in production?

A: Yes. The LMH6732MA/NOPB is the direct production substitute for the LMH6732MA. For ongoing manufacturing, the LMH6732MA/NOPB is the recommended selection due to active product status and regulatory compliance.
