Substitute Part Grouping Explanation

Substitution of the LMH6626MM is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the LMH6626MM/NOPB, which maintains identical electrical specifications including slew rate, gain bandwidth product, bandwidth, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature range. Both parts feature the same dual-circuit voltage feedback amplifier architecture in the 8-VSSOP package with identical mechanical dimensions.

The substitution logic is based on the following critical parameters:

• Amplifier Type: Voltage Feedback (identical)
• Number of Circuits: 2 (identical)
• Slew Rate: 400 V/µs (identical)
• Gain Bandwidth Product: 1.5 GHz (identical)
• -3dB Bandwidth: 95 MHz (identical)
• Current - Input Bias: 13 µA (identical)
• Voltage - Input Offset: 100 µV (identical)
• Current - Supply: 12 mA per channel (identical)
• Current - Output / Channel: 80 mA (identical)
• Supply Voltage Range: 5 V to 12 V (identical)
• Operating Temperature: -40°C to 125°C (identical)
• Package / Case: 8-TSSOP, 8-MSOP, 8-VSSOP (identical)

The LMH6626MM/NOPB differs only in product status (Active versus Obsolete) and packaging format (Tape & Reel versus standard), with improved RoHS compliance status.

Engineering Selection Recommendations

The LMH6626MM/NOPB is the direct parametric equivalent for the obsolete LMH6626MM. Selection of the LMH6626MM/NOPB is supported by the following engineering factors:

Product Status: The LMH6626MM/NOPB maintains Active product status, ensuring ongoing manufacturer support, availability, and technical documentation. The original LMH6626MM is classified as Obsolete, which restricts future procurement and support options.

Regulatory Compliance: The LMH6626MM/NOPB achieves ROHS3 compliance, meeting current environmental and regulatory requirements for electronic components in regulated markets. The original LMH6626MM is RoHS non-compliant, which may present compliance barriers in new designs or applications subject to RoHS directives.

Electrical Equivalence: All electrical parameters are identical between the two parts, including slew rate, bandwidth, gain-bandwidth product, bias current, offset voltage, supply current, output current, and supply voltage specifications. This ensures direct functional substitution without circuit redesign.

Mechanical Compatibility: Both parts utilize identical 8-VSSOP packaging with matching pin configurations and mechanical dimensions (0.118", 3.00mm Width). PCB layout and footprint compatibility is maintained.

Packaging Availability: The LMH6626MM/NOPB is available in Tape & Reel format, supporting automated assembly processes and high-volume production requirements.
