Supply voltage range: 4.5V to 12V minimum overlap
Operating temperature range compatibility
Surface mount packaging in SOT-23-5 or equivalent footprint

Substitution Categories:

Category 1: Direct Equivalent (Identical Electrical Specifications) LMH6723MF/NOPB maintains identical electrical performance with the main part. This substitute differs only in packaging format (Tape & Reel) and product status (Active vs. Obsolete), making it a direct functional replacement.

Category 2: Enhanced Performance Substitutes (Higher Bandwidth/Slew Rate) AD8014ARTZ-R2 and AD8014ARTZ-REEL7 provide superior electrical performance with 4600V/µs slew rate and 480 MHz bandwidth, exceeding the LMH6723MF specifications. These parts maintain compatible supply voltage ranges and operating temperatures but feature different output current and supply current characteristics.

Category 3: Partial Specification Substitutes (Reduced Operating Temperature Range) LT1395CS5#TRMPBF and LT1395CS5#TRPBF offer comparable performance with 800V/µs slew rate and 400 MHz bandwidth. These parts operate within 0°C to 70°C temperature range, which is narrower than the LMH6723MF specification of -40°C to 85°C. Package format is TSOT-23-5 (thin variant).

Engineering Selection Recommendations

For Direct Replacement (Identical Performance): LMH6723MF/NOPB is the primary substitute when maintaining exact electrical specifications is required. This part is manufactured by Texas Instruments with identical performance characteristics to the obsolete LMH6723MF. The part is active and ROHS3 compliant, addressing regulatory requirements. Packaging format is Tape & Reel (TR), suitable for automated assembly processes.

For Enhanced Performance Applications: AD8014ARTZ-REEL7 is selected when higher slew rate (4600V/µs) and bandwidth (480 MHz) are beneficial to the application. This Analog Devices part is active and ROHS3 compliant. The higher performance characteristics do not compromise compatibility with the 4.5V to 12V supply range and -40°C to 85°C operating temperature. Note that output current per channel is reduced to 50 mA compared to the original 110 mA specification.

For Temperature-Constrained Applications: LT1395CS5#TRMPBF and LT1395CS5#TRPBF are suitable only when operating temperature requirements do not exceed 0°C to 70°C. These parts offer improved slew rate (800V/µs) and bandwidth (400 MHz) relative to the original specification. Both parts are active and ROHS3 compliant. Package format is TSOT-23-5 (thin variant), which maintains SOT-23-5 footprint compatibility.

Compliance Considerations: The original LMH6723MF is RoHS non-compliant. All recommended substitutes (LMH6723MF/NOPB, AD8014ARTZ-REEL7, LT1395CS5#TRMPBF, LT1395CS5#TRPBF) are ROHS3 compliant, supporting modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can LMH6723MF/NOPB be used as a direct replacement for LMH6723MF?

A: Yes. LMH6723MF/NOPB is electrically identical to LMH6723MF, with identical slew rate (600V/µs), bandwidth (370 MHz), and all electrical specifications. The difference is packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete). Both use SOT-23-5 packaging.

Q: What are the key differences between LMH6723MF and AD8014ARTZ-REEL7?

A: AD8014ARTZ-REEL7 provides superior performance with 4600V/µs slew rate and 480 MHz bandwidth compared to LMH6723MF's 600V/µs and 370 MHz. However, output current is reduced from 110 mA to 50 mA. Supply voltage range (4.5V to 12V) and operating temperature (-40°C to 85°C) are compatible. Both use SOT-23-5 packaging.

Q: Are LT1395CS5#TRMPBF and LT1395CS5#TRPBF suitable for all LMH6723MF applications?

A: LT1395CS5#TRMPBF and LT1395CS5#TRPBF are suitable only for applications operating within 0°C to 70°C temperature range. The original LMH6723MF operates from -40°C to 85°C. If your application requires the full temperature range, these parts are not appropriate. Package format is TSOT-23-5 (thin variant), which is footprint-compatible with SOT-23-5.

Q: What is the difference between LT1395CS5#TRMPBF and LT1395CS5#TRPBF?

A: Both parts are electrically identical with 800V/µs slew rate and 400 MHz bandwidth. The difference is in packaging designation (TRMPBF vs. TRPBF), which reflects different tape and reel specifications. Electrical performance and pin configuration are identical.

Q: Is the TSOT-23-5 package of LT1395 parts compatible with SOT-23-5 footprints?

A: TSOT-23-5 (thin variant) maintains the same pin configuration and footprint as standard SOT-23-5. The primary difference is reduced package height. TSOT-23-5 parts are physically compatible with SOT-23-5 PCB layouts.

Q: Why is LMH6723MF classified as obsolete?

A: The LMH6723MF is listed as obsolete by Texas Instruments. LMH6723MF/NOPB is the active equivalent part from the same manufacturer, providing identical electrical specifications with current production status and RoHS compliance.

Q: Which substitute part has the highest inventory availability?

A: LT1395CS5#TRMPBF has the highest inventory with 4903 pieces in stock, followed by AD8014ARTZ-REEL7 with 3410 pieces. LMH6723MF/NOPB has 1450 pieces available.

Q: Are all substitute parts RoHS compliant?

A: LMH6723MF/NOPB, AD8014ARTZ-REEL7, LT1395CS5#TRMPBF, and LT1395CS5#TRPBF are all ROHS3 compliant. The original LMH6723MF is RoHS non-compliant. AD8014ARTZ-R2 RoHS status is not specified in the provided data.
