LMH6624MAX Equivalent & Substitute Parts

Part Overview

The LMH6624MAX is a voltage feedback amplifier integrated circuit manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as a linear amplifier with a single circuit configuration, designed for high-speed signal processing applications requiring 1.5 GHz gain bandwidth product and 400V/µs slew rate performance.

The LMH6624MAX carries an obsolete product status. Locating equivalent substitute parts is necessary for ongoing system support, design updates, and procurement continuity when original inventory becomes unavailable or when design requirements mandate compliance with current manufacturing standards.

Substitute Part Grouping Explanation

Substitution eligibility for the LMH6624MAX is determined by strict parametric equivalence across all electrical and mechanical specifications. The following criteria establish valid substitute relationships:

Electrical Performance Parameters:

• Amplifier type must be voltage feedback
• Single circuit configuration required
• Slew rate: 400V/µs (exact match)
• Gain bandwidth product: 1.5 GHz (exact match)
• -3dB bandwidth: 95 MHz (exact match)
• Input bias current: 13 µA (exact match)
• Input offset voltage: 100 µV (exact match)
• Supply current: 12 mA (exact match)
• Output current per channel: 100 mA (exact match)
• Supply voltage range: 5V to 12V (exact match)
• Operating temperature: -40°C to 125°C (exact match)

Mechanical & Packaging Parameters:

• Mounting type: Surface mount (required)
• Package type: 8-SOIC with 0.154" (3.90mm) width (exact match)

Compliance & Status:

• RoHS compliance status may differ between original and substitute
• Product status may transition from obsolete to active
• All other regulatory certifications (REACH, ECCN, HTSUS) must remain unchanged

Parameter Comparison

Engineering Selection Recommendations

The LMH6624MAX/NOPB is a direct parametric equivalent to the LMH6624MAX. All electrical performance specifications, operating characteristics, and mechanical package dimensions are identical.

Product Status Consideration: The LMH6624MAX carries obsolete status, while the LMH6624MAX/NOPB is classified as active. For new designs, ongoing production, or long-term system support, the active-status LMH6624MAX/NOPB is the appropriate selection to ensure continued component availability and manufacturing support from Texas Instruments.

Compliance Consideration: The LMH6624MAX is RoHS non-compliant. The LMH6624MAX/NOPB achieves ROHS3 compliance. Systems subject to RoHS regulatory requirements must use the LMH6624MAX/NOPB variant.

Packaging Consideration: The LMH6624MAX is supplied in bulk packaging. The LMH6624MAX/NOPB is supplied in tape and reel (TR) format, standard for automated assembly processes. Packaging selection depends on procurement volume and assembly methodology.

Electrical Performance: Both parts deliver identical electrical performance across all specified parameters. Pin-for-pin compatibility and functional equivalence are confirmed. Direct substitution in existing circuit designs is supported without modification.

Frequently Asked Questions (FAQ)

Q: Can LMH6624MAX/NOPB replace LMH6624MAX in existing designs?

A: Yes. The LMH6624MAX/NOPB is electrically and mechanically equivalent to the LMH6624MAX. All electrical parameters, operating ranges, and package dimensions are identical. Pin-for-pin compatibility is confirmed. Direct substitution is supported without circuit modification.

Q: What is the difference between LMH6624MAX and LMH6624MAX/NOPB?

A: The primary differences are product status, RoHS compliance, and packaging format. The LMH6624MAX is obsolete and RoHS non-compliant, supplied in bulk. The LMH6624MAX/NOPB is active, ROHS3 compliant, and supplied in tape and reel format. Electrical specifications are identical.

Q: Why should I use LMH6624MAX/NOPB instead of LMH6624MAX?

A: The LMH6624MAX/NOPB is recommended for new designs and ongoing production because it carries active product status, ensuring continued availability and manufacturing support. It also meets ROHS3 compliance requirements for regulated applications. The obsolete status of LMH6624MAX indicates limited future availability.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance. Slew rate, gain bandwidth product, bandwidth, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature specifications are identical across both variants.

Q: What packaging formats are available?

A: The LMH6624MAX is supplied in bulk packaging. The LMH6624MAX/NOPB is supplied in tape and reel (TR) format. Tape and reel packaging is standard for automated surface mount assembly. Bulk packaging is suitable for manual assembly or lower-volume applications.

Q: Is the 8-SOIC package identical between both parts?

A: Yes. Both parts use the 8-SOIC package with 0.154" (3.90mm) width. Package dimensions, pin pitch, and mechanical specifications are identical. PCB footprints and assembly processes are interchangeable.

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

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) packaging, which is associated with RoHS compliance. This designation confirms the part meets ROHS3 lead-free requirements.

Q: Can I use LMH6624MAX in applications requiring RoHS compliance?

A: No. The LMH6624MAX is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the LMH6624MAX/NOPB variant, which is ROHS3 compliant.
