Substitute Part Grouping Explanation

Substitution of the OP467GS is determined by the following critical parameters: amplifier type classification, number of circuits, package form factor, mounting technology, and electrical performance specifications including slew rate, gain bandwidth product, input bias current, and supply voltage range.

The substitute parts are grouped into two categories:

Direct Packaging Equivalent: OP467GSZ represents the active production variant of the OP467 base product, maintaining identical electrical specifications and package dimensions while differing only in product status and packaging format (Tube versus unspecified for the original OP467GS).

Functional Alternatives: The LT1125MPSW and LT1359 series parts provide operational amplifier functionality in 4-circuit configurations with 16-SOIC packaging. These alternatives differ in amplifier type classification, electrical performance parameters, and operating temperature ranges, requiring engineering evaluation for specific application requirements.

Substitution eligibility is determined by:

Number of circuits: 4 (mandatory match)
Package / Case: 16-SOIC surface mount (mandatory match)
Mounting Type: Surface Mount (mandatory match)
Electrical performance: Slew rate, gain bandwidth product, supply voltage range, and input characteristics must be compatible with application requirements

Engineering Selection Recommendations

Primary Recommendation: OP467GSZ

The OP467GSZ is the direct active production equivalent of the OP467GS. This part maintains identical electrical specifications, package dimensions, and operating characteristics while offering the advantage of active product status. The OP467GSZ is ROHS3 compliant and available in higher inventory quantities, supporting long-term supply chain continuity. Selection of OP467GSZ is appropriate for applications where the original OP467GS specifications are required without modification.

Secondary Recommendations: LT1125MPSW Series

The LT1125MPSW#PBF and LT1125MPSW#TRPBF parts provide general-purpose amplifier functionality with reduced supply current (2.3 mA versus 8 mA per channel) and improved input bias current characteristics (8 nA versus 150 nA). These parts support extended operating temperature range (-55°C to 125°C) and higher maximum supply voltage (44 V versus 36 V). The LT1125 series is suitable for applications where lower power consumption and enhanced temperature performance are beneficial. Both packaging formats (Tube and Tape & Reel) are available with ROHS3 compliance.

Tertiary Recommendations: LT1359 Series

The LT1359 series comprises voltage feedback amplifiers with higher slew rate (600 V/µs versus 350 V/µs) and lower supply current (2 mA versus 8 mA per channel). Four variants are available: LT1359CS#PBF and LT1359CS#TRPBF (commercial temperature range, 0°C to 70°C) and LT1359IS#PBF and LT1359IS#TRPBF (industrial temperature range, -40°C to 85°C). The LT1359IS variants match the operating temperature range of the OP467GS. All LT1359 parts are ROHS3 compliant. Selection of LT1359 parts is appropriate for applications requiring higher slew rate performance and lower power consumption, with the understanding that amplifier type classification differs from the original part.

All substitute parts are manufactured by Analog Devices Inc., ensuring consistent quality and technical support standards.

Frequently Asked Questions (FAQ)

Q: Can OP467GSZ be used as a direct replacement for OP467GS?

A: Yes. The OP467GSZ maintains identical electrical specifications, package form factor, and operating characteristics as the OP467GS. The primary difference is product status: OP467GSZ is active production while OP467GS is obsolete. OP467GSZ is the recommended direct substitute.

Q: What are the key differences between OP467GS and LT1125MPSW parts?

A: Both are 4-circuit general-purpose amplifiers in 16-SOIC packages. The LT1125MPSW offers lower supply current (2.3 mA versus 8 mA per channel), lower input bias current (8 nA versus 150 nA), extended temperature range (-55°C to 125°C versus -40°C to 85°C), and higher maximum supply voltage (44 V versus 36 V). Slew rate is lower (4.5 V/µs versus 350 V/µs) and gain bandwidth product is lower (12.5 MHz versus 28 MHz).

Q: What are the key differences between OP467GS and LT1359 parts?

A: Both are 4-circuit amplifiers in 16-SOIC packages. The LT1359 is classified as a voltage feedback amplifier rather than general purpose. The LT1359 offers higher slew rate (600 V/µs versus 350 V/µs), lower supply current (2 mA versus 8 mA per channel), and lower input bias current (120 nA versus 150 nA). The LT1359 has lower maximum supply voltage (30 V versus 36 V). The LT1359IS variants support the same operating temperature range as OP467GS (-40°C to 85°C).

Q: Are there package dimension differences between substitute parts?

A: Yes. The OP467GS and OP467GSZ use 16-SOIC packages with 0.295" (7.50mm) width. The LT1359 series uses 16-SOIC packages with 0.154" (3.90mm) width, representing a narrower package form. The LT1125MPSW series uses 16-SOIC packages with 0.295" (7.50mm) width, matching the original part dimensions. PCB layout modifications may be required when substituting OP467GS with LT1359 parts due to package width differences.

Q: What packaging formats are available for substitute parts?

A: OP467GSZ is available in Tube packaging. LT1125MPSW parts are available in both Tube (LT1125MPSW#PBF) and Tape & Reel (LT1125MPSW#TRPBF) formats. LT1359 parts are available in both Tube and Tape & Reel formats: LT1359CS#PBF (Tube), LT1359CS#TRPBF (Tape & Reel), LT1359IS#PBF (Tube), and LT1359IS#TRPBF (Tape & Reel).

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original OP467GS does not specify RoHS status. All substitute parts are also REACH unaffected where specified.

Q: Which substitute part should be selected for applications requiring the lowest power consumption?

A: The LT1359 series offers the lowest supply current at 2 mA per channel (x4 channels), compared to 8 mA for OP467GS and 2.3 mA for LT1125MPSW. Selection between LT1359CS and LT1359IS variants depends on operating temperature requirements: LT1359CS for 0°C to 70°C applications and LT1359IS for -40°C to 85°C applications.

Q: Which substitute part should be selected for applications requiring the highest slew rate?

A: The LT1359 series offers the highest slew rate at 600 V/µs, compared to 350 V/µs for OP467GS and 4.5 V/µs for LT1125MPSW.

Q: Can LT1125MPSW be used in applications requiring the full -40°C to 85°C temperature range?

A: No. LT1125MPSW parts support -55°C to 125°C operating temperature range, which exceeds the -40°C to 85°C requirement. However, if the application requires operation only within the -40°C to 85°C range, LT1125MPSW parts are suitable. For applications requiring exactly -40°C to 85°C operation, LT1359IS variants are the appropriate choice among the LT1359 series.

Q: What is the inventory status of substitute parts?

A: OP467GSZ: 2025 pieces. LT1125MPSW#PBF: 1900 pieces. LT1125MPSW#TRPBF: 2030 pieces. LT1359CS#PBF: 2104 pieces. LT1359CS#TRPBF: 4358 pieces. LT1359IS#PBF: 1143 pieces. LT1359IS#TRPBF: 1102 pieces. All parts are listed as new original stock.
