LMH6732MF Equivalent & Substitute Parts

Part Overview

The LMH6732MF is a current feedback amplifier integrated circuit manufactured by Texas Instruments, housed in a SOT-23-6 surface mount package. This device is classified as a linear amplifier with a single circuit configuration and is currently marked as obsolete in the product lifecycle. The LMH6732MF delivers high-speed amplification with a slew rate of 2700V/µs and a -3dB bandwidth of 540 MHz, making it suitable for applications requiring fast signal processing and wide bandwidth performance. Due to its obsolete status, identifying equivalent substitute parts is essential for design continuity, procurement planning, and long-term product support.

Substitute Part Grouping Explanation

Substitution of the LMH6732MF is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier Type: Current Feedback architecture
• Slew Rate: 2700V/µs
• -3dB Bandwidth: 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: 9V to 12V
• Operating Temperature Range: -40°C to 85°C

Physical & Packaging Criteria:

• Package Type: SOT-23-6
• Mounting Type: Surface Mount
• Number of Circuits: 1

The substitute part LMH6732MF/NOPB meets all electrical and physical specifications of the main part. The primary distinction is packaging format (Bulk versus Tape & Reel) and product status (Active versus Obsolete). Both parts share identical electrical characteristics and pinout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LMH6732MF/NOPB

The LMH6732MF/NOPB is a direct electrical and mechanical equivalent to the LMH6732MF. All critical performance parameters—slew rate, bandwidth, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature—are identical. Both devices utilize the SOT-23-6 surface mount package with identical pinout configuration.

The LMH6732MF/NOPB carries an Active product status, ensuring ongoing availability and manufacturer support, whereas the main part is classified as Obsolete. This status difference makes the LMH6732MF/NOPB the preferred choice for new designs and long-term procurement strategies.

The packaging difference (Bulk versus Tape & Reel) does not affect electrical performance or functional compatibility. Selection between packaging formats depends on procurement volume and assembly line requirements.

Both parts comply with identical regulatory classifications: ECCN EAR99 and HTSUS 8542.33.0001. RoHS compliance status and REACH applicability should be verified against current regulatory requirements at the time of procurement.

Frequently Asked Questions (FAQ)

Q: Can the LMH6732MF/NOPB be used as a direct replacement for the LMH6732MF?

A: Yes. The LMH6732MF/NOPB is electrically and mechanically equivalent. All electrical specifications, including slew rate (2700V/µs), bandwidth (540 MHz), input bias current (2 µA), input offset voltage (3 mV), supply current (9 mA), output current (115 mA), and supply voltage range (9V to 12V) are identical. The SOT-23-6 package and pinout are the same, enabling direct substitution in existing circuit designs.

Q: What is the difference between the LMH6732MF and LMH6732MF/NOPB?

A: The primary differences are manufacturer designation (Texas Instruments versus National Semiconductor), product status (Obsolete versus Active), and packaging format (Tape & Reel versus Bulk). All electrical and mechanical specifications are identical. The "/NOPB" suffix indicates lead-free (no lead) packaging compliance.

Q: Why is the LMH6732MF marked as Obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, technology evolution, and production lifecycle decisions. The LMH6732MF/NOPB, carrying Active status, represents the current production equivalent and is recommended for ongoing applications.

Q: Are there any compatibility concerns when switching from Tape & Reel to Bulk packaging?

A: No electrical or functional compatibility concerns exist. The difference is purely logistical. Tape & Reel packaging is optimized for automated assembly lines, while Bulk packaging is suitable for manual assembly or lower-volume applications. The component itself is identical.

Q: What is the operating temperature range for both parts?

A: Both the LMH6732MF and LMH6732MF/NOPB operate across the temperature range of -40°C to 85°C, making them suitable for industrial and commercial applications.

Q: Are there any regulatory or compliance differences between the two parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. RoHS compliance status and REACH applicability should be confirmed with the supplier at the time of procurement, as regulatory requirements may change.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating minimal moisture sensitivity and simplified handling and storage requirements compared to higher MSL ratings.
