Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA3692IDRG4 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Criteria:

• Number of circuits: 3 (fixed requirement)
• -3dB bandwidth: 280 MHz (minimum threshold)
• Slew rate: ≥2000V/µs (minimum threshold)
• Supply current: 15.3 mA (nominal operating point)
• Output current per channel: 190 mA (load capability)
• Supply voltage range: 5V ~ 12V single supply or ±2.5V ~ 6V dual supply (operational envelope)

Mechanical & Environmental Compatibility Criteria:

• Package type: 16-SOIC (0.154", 3.90mm Width) (pin-for-pin requirement)
• Mounting type: Surface Mount (assembly compatibility)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)
• Moisture sensitivity: MSL 2 (1 Year) (handling and storage requirement)

The OPA3691ID qualifies as a manufacturer-recommended substitute based on full alignment with these parameters. Both devices share identical package geometry, supply voltage specifications, output current ratings, and environmental compliance certifications. The OPA3691ID maintains the 280 MHz bandwidth specification while exceeding the slew rate requirement at 2100V/µs, ensuring functional equivalence in buffer applications.

Engineering Selection Recommendations

The OPA3691ID is the appropriate substitute for the obsolete OPA3692IDRG4 based on the following engineering criteria:

Product Status Alignment: The OPA3691ID maintains active product status with Texas Instruments, ensuring long-term availability, technical support, and supply chain continuity. The OPA3692IDRG4 is classified as obsolete, creating procurement risk and limiting access to manufacturer documentation and support resources.

Regulatory & Compliance Equivalence: Both devices maintain ROHS3 compliance and identical MSL 2 (1 Year) moisture sensitivity ratings, ensuring compatibility with current manufacturing processes, storage protocols, and environmental regulations. REACH status is unaffected for both components.

Electrical Performance: The OPA3691ID meets or exceeds all critical electrical parameters of the OPA3692IDRG4. The 280 MHz bandwidth specification is maintained, while the slew rate is increased to 2100V/µs, providing enhanced performance margin. Supply current, output current per channel, and supply voltage ranges are identical, ensuring direct functional replacement without circuit redesign.

Package & Assembly Compatibility: Both devices utilize the 16-SOIC (0.154", 3.90mm Width) package with surface mount configuration, enabling direct PCB layout compatibility and eliminating assembly process modifications.
