Substitute Part Grouping Explanation

Substitute parts for the LT1395CS8#TRPBF are qualified based on the following substitution criteria:

Topology Match: Both substitute parts employ current feedback amplifier architecture, maintaining identical circuit topology and functional behavior.

Circuit Count: Single-circuit configuration preserved across all qualified substitutes.

Package Compatibility: All parts utilize 8-SOIC surface mount packaging with identical 0.154" (3.90mm) width, ensuring direct PCB footprint compatibility.

Electrical Performance Envelope: Substitute parts operate within the defined supply voltage range (4.5 V to 12 V minimum and maximum), support the required input offset voltage specification (1 mV), and deliver output current capability (110 mA) that meets or exceeds the original part requirement (80 mA).

Compliance Status: All substitute parts maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring equivalent environmental and manufacturing compatibility.

The Texas Instruments LMH6723MA/NOPB and LMH6723MAX/NOPB represent functionally equivalent alternatives with extended operating temperature range and reduced supply current consumption compared to the primary part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The LT1395CS8#TRPBF remains the specified component when the original design parameters require 800 V/µs slew rate and 400 MHz bandwidth performance. This part is active and in production with established supply availability.

Substitute Selection - LMH6723MA/NOPB: This Texas Instruments equivalent is suitable for applications where the operating temperature range can extend to -40°C to 85°C and where reduced supply current consumption (1 mA versus 4.6 mA) provides system-level power efficiency benefits. The 600 V/µs slew rate and 370 MHz bandwidth remain adequate for applications not requiring the maximum performance envelope of the primary part. Tube packaging is specified for this variant.

Substitute Selection - LMH6723MAX/NOPB: This variant offers identical electrical specifications to the LMH6723MA/NOPB with tape and reel (TR) packaging, matching the original part's packaging format. Selection of this variant is appropriate when tape and reel format is required for automated assembly processes and when the extended temperature range and reduced supply current are compatible with system requirements.

Compliance Assurance: All three parts maintain RoHS3 compliance and unlimited moisture sensitivity rating, confirming equivalent environmental qualification and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LMH6723MA/NOPB or LMH6723MAX/NOPB be used as direct replacements for the LT1395CS8#TRPBF?

A: Both Texas Instruments parts are functionally equivalent substitutes based on matching current feedback amplifier topology, single-circuit configuration, and 8-SOIC package form factor. The electrical performance envelope (slew rate, bandwidth, output current, supply voltage range) of the substitute parts meets the requirements of applications designed for the LT1395CS8#TRPBF. However, the substitute parts deliver lower slew rate (600 V/µs versus 800 V/µs) and reduced bandwidth (370 MHz versus 400 MHz), which must be verified as acceptable for the specific circuit application.

Q: What is the difference between LMH6723MA/NOPB and LMH6723MAX/NOPB?

A: Both parts are identical in electrical specifications and performance characteristics. The primary difference is packaging format: LMH6723MA/NOPB is supplied in tube packaging, while LMH6723MAX/NOPB is supplied in tape and reel (TR) format. Selection between these variants depends on assembly process requirements and inventory handling procedures.

Q: Are there any temperature range limitations when substituting the LT1395CS8#TRPBF?

A: The LT1395CS8#TRPBF operates from 0°C to 70°C. The substitute parts (LMH6723MA/NOPB and LMH6723MAX/NOPB) operate from -40°C to 85°C, providing an extended temperature range. If the application requires operation only within the 0°C to 70°C range, the substitute parts are fully compatible. Applications requiring operation below 0°C or above 70°C must use the substitute parts.

Q: Do the substitute parts require different PCB layout or footprint modifications?

A: No. All three parts utilize identical 8-SOIC (0.154", 3.90mm width) surface mount packaging. The PCB footprint, land pattern, and layout requirements are identical across all parts, enabling direct substitution without PCB redesign.

Q: What are the supply current differences between the primary part and substitutes?

A: The LT1395CS8#TRPBF draws 4.6 mA supply current, while both LMH6723MA/NOPB and LMH6723MAX/NOPB draw 1 mA. This 4.6× reduction in supply current consumption in the substitute parts can provide significant system-level power efficiency benefits in battery-powered or thermally constrained applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. The LT1395CS8#TRPBF, LMH6723MA/NOPB, and LMH6723MAX/NOPB are all RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1), confirming equivalent environmental qualification and manufacturing process compatibility.
