Substitute Part Grouping Explanation

Substitution analysis for the OP97FS is structured into two distinct categories based on electrical and mechanical compatibility:

Direct Equivalent (Packaging Variant): The OP97FSZ represents a direct functional equivalent with identical electrical specifications. This substitution is based on matching amplifier type (general purpose), circuit count (1), package form factor (8-SOIC), and all critical electrical parameters including slew rate, bandwidth, bias current, offset voltage, supply current, and supply voltage range. The primary distinction is packaging format (tube versus unspecified original packaging) and product status transition from obsolete to active.

Similar Substitutes (Amplifier Type Variation): The LT1167 series components (LT1167CS8-1#PBF, LT1167CS8-1#TRPBF, LT1167IS8#TR, LT1167IS8-1#PBF, LT1167IS8-1#TRPBF) share the 8-SOIC package footprint and surface mount mounting type. However, these devices are instrumentation amplifiers rather than general-purpose amplifiers. Substitution with LT1167 variants is permissible only when circuit design accommodates the following parameter differences: higher slew rate (1.2 V/µs versus 0.2 V/µs), gain bandwidth product specification (1 MHz) instead of -3dB bandwidth, higher input bias current (80 pA versus 30 pA), lower input offset voltage (20 µV versus 30 µV), increased supply current (900 µA versus 380 µA), and restricted supply voltage minimum (4.6 V versus 4 V). Operating temperature range varies by specific LT1167 variant.

Engineering Selection Recommendations

OP97FSZ Selection: The OP97FSZ is the primary substitute for OP97FS applications. This component maintains identical electrical specifications and package footprint while offering active product status and full RoHS3 compliance with REACH unaffected certification. Selection of OP97FSZ eliminates obsolescence risk and ensures regulatory compliance for new production and long-term supply availability.

LT1167 Series Selection: The LT1167 instrumentation amplifier variants are suitable substitutes only when circuit topology and application requirements accommodate instrumentation amplifier characteristics. All LT1167 variants maintain 8-SOIC package compatibility and surface mount mounting. Selection among LT1167 variants depends on packaging requirements (tube, tape & reel) and operating temperature specifications. LT1167IS8-1#PBF and LT1167IS8-1#TRPBF support the full -40°C to 85°C temperature range matching the original OP97FS specification. LT1167CS8-1#PBF and LT1167CS8-1#TRPBF operate within 0°C to 70°C range and are suitable for commercial temperature applications only. All LT1167 variants provide active product status and full RoHS3 compliance with REACH unaffected certification.

Compliance Considerations: The OP97FS obsolete status necessitates transition to active components. Both OP97FSZ and LT1167 series options provide ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can OP97FSZ be used as a direct replacement for OP97FS in existing designs?

A: Yes. The OP97FSZ provides identical electrical specifications, package form factor (8-SOIC), and mounting type (surface mount). No circuit modifications are required for direct substitution. The primary difference is packaging format and active product status.

Q: What are the key differences between OP97FS and LT1167 series components?

A: The OP97FS is a general-purpose operational amplifier, while LT1167 devices are instrumentation amplifiers. Functional differences include: LT1167 has higher slew rate (1.2 V/µs versus 0.2 V/µs), higher input bias current (80 pA versus 30 pA), lower input offset voltage (20 µV versus 30 µV), and higher supply current (900 µA versus 380 µA). LT1167 also has restricted maximum supply voltage (36 V versus 40 V) and minimum supply voltage (4.6 V versus 4 V). These differences require circuit design evaluation before substitution.

Q: Which LT1167 variant should be selected for industrial temperature applications?

A: LT1167IS8-1#PBF (tube packaging) or LT1167IS8-1#TRPBF (tape & reel packaging) support the full -40°C to 85°C operating temperature range, matching the original OP97FS specification. LT1167CS8-1#PBF and LT1167CS8-1#TRPBF are restricted to 0°C to 70°C and are suitable for commercial temperature applications only.

Q: What packaging options are available for substitute components?

A: OP97FSZ is supplied in tube packaging. LT1167 variants are available in tube packaging (LT1167CS8-1#PBF, LT1167IS8-1#PBF) or tape & reel packaging (LT1167CS8-1#TRPBF, LT1167IS8-1#TRPBF). Selection depends on production assembly requirements and inventory management practices.

Q: Are all substitute components RoHS3 compliant?

A: Yes. OP97FSZ and all LT1167 variants are ROHS3 compliant with REACH unaffected status, supporting current regulatory requirements for electronic component manufacturing and distribution.

Q: Can LT1167 components be used in applications requiring the exact electrical specifications of OP97FS?

A: LT1167 substitution requires circuit design evaluation. Applications with strict requirements for slew rate (0.2 V/µs), input bias current (30 pA maximum), or supply voltage range (4 V to 40 V) may not be compatible with LT1167 specifications. General-purpose amplifier applications with flexible performance tolerances can accommodate LT1167 substitution.

Q: What is the inventory status of substitute components?

A: OP97FSZ has 30,036 units in stock. LT1167 variants have varying inventory levels: LT1167CS8-1#PBF (3,100 units), LT1167CS8-1#TRPBF (2,028 units), LT1167IS8-1#PBF (2,300 units), and LT1167IS8-1#TRPBF (1,121 units). All components are new original stock from Analog Devices Inc.
