LT1677IS8 Equivalent & Substitute Parts

Part Overview

The LT1677IS8 is a general purpose operational amplifier manufactured by Analog Devices Inc., designed for rail-to-rail signal processing applications. This single-circuit amplifier operates across a wide supply voltage range of 3V to 36V and is housed in an 8-SOIC surface mount package. The device is currently in active production status and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging preferences, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution of the LT1677IS8 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part LT1677IS8#PBF maintains identical specifications across all performance characteristics including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range. Both parts share the same base product number (LT1677), amplifier classification, and 8-SOIC package geometry.

The primary distinction between the main part and its substitute is the packaging format: the LT1677IS8 is supplied in standard packaging, while the LT1677IS8#PBF variant is supplied in tube packaging. This packaging difference does not affect electrical performance, thermal characteristics, or mechanical compatibility in circuit board applications. Both parts are manufactured by Analog Devices Inc., maintain active product status, and carry identical compliance certifications including RoHS3 compliance and REACH unaffected status.

Substitution is valid when the following parameters are matched:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Slew Rate: 2.5 V/µs
• Gain Bandwidth Product: 7.2 MHz
• Supply Voltage Range: 3V to 36V
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Parameter Comparison

Engineering Selection Recommendations

The LT1677IS8#PBF is a direct electrical and mechanical equivalent to the LT1677IS8. Both parts are manufactured by Analog Devices Inc. and maintain active product status with identical performance specifications. Selection between these parts is based on packaging and inventory requirements rather than functional differences.

The LT1677IS8 is supplied in standard packaging format with 3,747 units currently in stock. The LT1677IS8#PBF is supplied in tube packaging format with 2,300 units currently in stock. Both variants carry identical RoHS3 compliance certification, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), making either part suitable for applications requiring environmental compliance.

For applications where tube packaging is preferred for automated assembly processes or where standard packaging inventory is unavailable, the LT1677IS8#PBF provides equivalent performance without modification to circuit design or board layout. The 8-SOIC package geometry remains constant across both variants, ensuring footprint compatibility on printed circuit boards.

Frequently Asked Questions (FAQ)

Q: Can the LT1677IS8#PBF be used as a direct replacement for the LT1677IS8?

A: Yes. The LT1677IS8#PBF is electrically and mechanically equivalent to the LT1677IS8. All performance parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range are identical. The only difference is the packaging format (tube versus standard).

Q: What is the difference between the LT1677IS8 and LT1677IS8#PBF?

A: The primary difference is packaging format. The LT1677IS8 is supplied in standard packaging, while the LT1677IS8#PBF is supplied in tube packaging. This distinction affects handling and storage but does not impact electrical performance or circuit board compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LT1677IS8 and LT1677IS8#PBF are RoHS3 compliant and carry REACH unaffected status, making them suitable for applications requiring environmental compliance.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under normal storage conditions without special moisture control requirements.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes, from an electrical and mechanical standpoint. However, the packaging format difference (standard versus tube) may affect handling in automated pick-and-place equipment. Tube packaging is typically preferred for high-volume automated assembly processes.

Q: What is the operating temperature range for the LT1677IS8?

A: Both the LT1677IS8 and LT1677IS8#PBF operate across a temperature range of -40°C to 85°C, suitable for industrial and commercial applications.

Q: What supply voltage range does the LT1677IS8 support?

A: The LT1677IS8 operates with a supply voltage span from 3V (minimum) to 36V (maximum), providing flexibility for single-supply and dual-supply configurations.

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

A: Yes. Both the LT1677IS8 and LT1677IS8#PBF use the 8-SOIC package with dimensions of 0.154 inches (3.90mm width), ensuring identical printed circuit board footprints and layout compatibility.
