Engineering Selection Recommendations
Primary Recommendation: ISL55002IBZ-T7 or ISL55002IBZ-T13
The ISL55002IBZ-T7 and ISL55002IBZ-T13 are direct electrical and mechanical equivalents of the ISL55002IB-T7. Both parts maintain identical performance specifications across all measured parameters. The primary distinction is product status: both are classified as Active, whereas the original ISL55002IB-T7 is Obsolete. Additionally, both direct equivalents are ROHS3 Compliant, addressing regulatory requirements that the original part does not satisfy.
The ISL55002IBZ-T7 and ISL55002IBZ-T13 differ only in packaging format (Tape & Reel). Selection between these two variants depends on procurement and assembly requirements. Both are suitable for direct substitution without circuit modification.
Secondary Recommendation: THS4032ID (Texas Instruments)
The THS4032ID is a voltage feedback amplifier from Texas Instruments suitable for applications where the ISL55002IB-T7 direct equivalents are unavailable. This device maintains the same dual-channel configuration, 8-SOIC package geometry, and operating temperature range (-40°C to 85°C) as the original part. The THS4032ID is classified as Last Time Buy, indicating continued availability with defined end-of-life support.
The THS4032ID exhibits higher input bias current (3 µA versus 600 nA) and lower slew rate (100 V/µs versus 300 V/µs) compared to the ISL55002IB-T7. These differences require circuit evaluation to confirm compatibility with the intended application. The minimum supply voltage requirement is higher (9 V versus 4.5 V), which may restrict use in low-voltage applications.
Tertiary Recommendation: THS4022ID (Texas Instruments)
The THS4022ID is a voltage feedback amplifier with enhanced performance specifications suitable for applications requiring higher bandwidth. This device provides a slew rate of 470 V/µs and gain bandwidth product of 350 MHz, compared to 300 V/µs and 70 MHz for the ISL55002IB-T7. The THS4022ID maintains the same dual-channel configuration and 8-SOIC package footprint.
The THS4022ID is classified as Last Time Buy and operates across the temperature range -40°C to 85°C. The minimum supply voltage is 9 V, which may restrict use in applications designed for the 4.5 V minimum of the original part. Circuit redesign may be required to accommodate the higher input bias current (3 µA versus 600 nA).
Not Recommended: Rohm Semiconductor General Purpose Amplifiers
The BA4558RFJ-GE2, BA4560FJ-GE2, and BA4560RFJ-GE2 are general purpose operational amplifiers with significantly reduced bandwidth and slew rate specifications. These devices are not suitable substitutes for the ISL55002IB-T7 in applications requiring the specified voltage feedback performance characteristics. Selection of these parts is appropriate only for applications with substantially lower bandwidth requirements than those supported by the original device.
Frequently Asked Questions (FAQ)
Q: Can the ISL55002IBZ-T7 be used as a direct replacement for the ISL55002IB-T7?
A: Yes. The ISL55002IBZ-T7 is electrically and mechanically identical to the ISL55002IB-T7. Both devices share identical specifications for slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range. The primary difference is product status (Active versus Obsolete) and RoHS compliance (ROHS3 Compliant versus non-compliant). No circuit modifications are required for substitution.
Q: What is the difference between ISL55002IBZ-T7 and ISL55002IBZ-T13?
A: The ISL55002IBZ-T7 and ISL55002IBZ-T13 are electrically identical. The designation suffix (-T7 versus -T13) indicates different packaging formats or tape specifications for automated assembly. Both parts are Active status and ROHS3 Compliant. Selection between these variants depends on procurement format requirements and assembly equipment compatibility.
Q: Why does the THS4032ID have higher input bias current than the ISL55002IB-T7?
A: The THS4032ID and ISL55002IB-T7 employ different input stage architectures. The THS4032ID specifies 3 µA input bias current, while the ISL55002IB-T7 specifies 600 nA. This 5-fold difference reflects design trade-offs between bandwidth, noise, and power consumption. Applications sensitive to input bias current effects require circuit evaluation before substitution.
Q: Can the BA4560RFJ-GE2 replace the ISL55002IB-T7?
A: The BA4560RFJ-GE2 is not a suitable substitute for the ISL55002IB-T7 in applications requiring the specified performance. The BA4560RFJ-GE2 is a general purpose amplifier with a gain bandwidth product of 4 MHz and slew rate of 4 V/µs, compared to 70 MHz and 300 V/µs for the ISL55002IB-T7. This represents an 17.5-fold reduction in bandwidth and 75-fold reduction in slew rate. Substitution is appropriate only for applications with substantially reduced bandwidth requirements.
Q: What is the minimum supply voltage for the THS4022ID?
A: The THS4022ID requires a minimum supply voltage of 9 V, compared to 4.5 V for the ISL55002IB-T7. Applications designed to operate at supply voltages below 9 V cannot use the THS4022ID without circuit redesign. Verify supply voltage availability in the target application before selecting this substitute.
Q: Are all substitute parts RoHS compliant?
A: All substitute parts listed are ROHS3 Compliant. The original ISL55002IB-T7 is RoHS non-compliant. If RoHS compliance is a requirement, the ISL55002IBZ-T7 or ISL55002IBZ-T13 are the appropriate selections, as these are direct equivalents with ROHS3 Compliant status.
Q: What is the package compatibility between the ISL55002IB-T7 and substitute parts?
A: All substitute parts are housed in 8-SOIC packages with identical physical dimensions (0.154" width, 3.90mm width). Pin-to-pin compatibility is maintained across all listed substitutes. PCB footprints designed for the ISL55002IB-T7 accommodate all substitute parts without modification.
Q: Which substitute part has the closest electrical match to the ISL55002IB-T7?
A: The ISL55002IBZ-T7 and ISL55002IBZ-T13 are exact electrical matches to the ISL55002IB-T7. All measured parameters are identical, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current. These parts are the only true equivalents and are recommended for direct substitution.
