Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1672CS8#PBF is determined by the following critical parameters: single-circuit general purpose amplifier configuration, rail-to-rail output capability, 8-SOIC surface mount package format, supply voltage range compatibility (2.2 V to 36 V minimum), and operating temperature range (0°C to 70°C minimum). Parts meeting these core electrical and mechanical specifications are classified as functional equivalents.

The LT1494CS8#PBF represents a manufacturer-recommended equivalent from Analog Devices Inc., maintaining identical package geometry and supply specifications while operating in Active product status. The LM7301IM/NOPB and LM7301IMX/NOPB from Texas Instruments are classified as similar alternatives, offering the same package footprint and rail-to-rail output configuration but with extended operating temperature range and different electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

LT1494CS8#PBF is the primary equivalent for LT1672CS8#PBF replacement. Both devices are manufactured by Analog Devices Inc., share identical package geometry and supply voltage specifications, and maintain ROHS3 compliance with MSL 1 rating. The LT1494CS8#PBF is in Active product status with higher inventory availability (2431 pcs), providing superior long-term supply assurance compared to the Last Time Buy status of the LT1672CS8#PBF.

LM7301IMX/NOPB is the recommended Texas Instruments alternative for applications requiring extended operating temperature range (-40°C to 85°C). This device maintains Active product status and offers significantly higher inventory (9339 pcs). The LM7301IMX/NOPB is supplied in Tape & Reel packaging format, suitable for high-volume manufacturing environments. All three devices share identical 8-SOIC package footprint and ROHS3 compliance.

LM7301IM/NOPB is classified as Obsolete and should not be selected for new designs or long-term production applications despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can LT1494CS8#PBF directly replace LT1672CS8#PBF in existing designs?

A: Yes. Both devices share identical package geometry (8-SOIC), supply voltage range (2.2 V to 36 V), output current capability (1.5 mA), and operating temperature range (0°C to 70°C). Pin-to-pin compatibility is maintained. The LT1494CS8#PBF operates at lower slew rate (0.001 V/µs versus 0.005 V/µs) and lower gain bandwidth product (2.7 kHz versus 12 kHz), which may affect high-frequency performance in bandwidth-sensitive applications.

Q: What are the key differences between LT1672CS8#PBF and LM7301IMX/NOPB?

A: The LM7301IMX/NOPB offers extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), significantly higher slew rate (1.25 V/µs versus 0.005 V/µs), and higher gain bandwidth product (4 MHz versus 12 kHz). Supply voltage maximum is reduced to 32 V versus 36 V. Supply current consumption is substantially higher (720 µA versus 1.9 µA). Package footprint remains identical at 8-SOIC.

Q: Is packaging format interchangeable between tube and tape & reel options?

A: Packaging format (Tube versus Tape & Reel) affects component handling and assembly processes but does not alter electrical performance or pin compatibility. LT1672CS8#PBF is supplied in Tube format, while LM7301IMX/NOPB is supplied in Tape & Reel format. Selection depends on manufacturing process requirements and assembly equipment compatibility.

Q: Why is LM7301IM/NOPB listed as Obsolete?

A: LM7301IM/NOPB is classified as Obsolete by Texas Instruments, indicating discontinued production and no guaranteed future availability. This status makes it unsuitable for new designs or applications requiring long-term component supply. LM7301IMX/NOPB, the Tape & Reel variant, maintains Active status and should be selected instead.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. LT1672CS8#PBF, LT1494CS8#PBF, LM7301IM/NOPB, and LM7301IMX/NOPB are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What supply voltage considerations apply when substituting with LM7301IMX/NOPB?

A: LM7301IMX/NOPB maximum supply voltage is 32 V compared to 36 V for LT1672CS8#PBF. Applications operating at supply voltages between 32 V and 36 V require design modification or alternative component selection. Minimum supply voltage (1.8 V) is lower than LT1672CS8#PBF (2.2 V), providing expanded low-voltage operation capability.
