Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP284FS-REEL is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Dual-circuit configuration (2 circuits per package)
• Rail-to-rail output capability
• 8-SOIC surface mount package (0.154", 3.90mm width)
• Operating temperature range: -40°C to 125°C
• Supply voltage compatibility: minimum 3V to maximum 36V

Secondary Compatibility Parameters:

• Slew rate performance (4V/µs baseline)
• Gain bandwidth product (4.25 MHz baseline)
• Input bias current (80 nA baseline)
• Input offset voltage (175 µV baseline)
• Output current per channel (10 mA baseline)

Substitute parts are classified into two categories: direct equivalents (identical electrical specifications) and similar alternatives (compatible but with enhanced or modified performance characteristics). All substitute parts maintain the same package footprint and mounting type, ensuring mechanical compatibility in existing PCB designs.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitution:

The OP284FSZ-REEL represents the direct equivalent to the OP284FS-REEL, maintaining identical electrical specifications across all measured parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, and output current per channel. The OP284FSZ-REEL is currently in active production status with ROHS3 compliance and REACH unaffected certification. This part is the primary recommendation for direct replacement in existing designs where the OP284FS-REEL is specified.

Enhanced Performance Alternatives:

The ADA4084-2ARZ-RL offers improved performance characteristics with higher slew rate (4.6V/µs), significantly higher gain bandwidth product (15.9 MHz), lower input offset voltage (30 µV), and increased output current per channel (30 mA). However, the maximum supply voltage is limited to 30V compared to the 36V maximum of the OP284FS-REEL. This part is suitable for applications requiring higher bandwidth and lower offset voltage within the 3V to 30V supply range.

The OPA2172ID and OPA2172IDR (identical electrical specifications, differing only in packaging format) provide the highest output current per channel (75 mA) and slew rate (10V/µs) among all alternatives. These parts require a minimum supply voltage of 4.5V, restricting use in applications requiring operation below this threshold. Both are ROHS3 compliant with active product status.

Automotive-Grade Alternative:

The OPA2171AQDRQ1 is qualified to AEC-Q100 automotive standards with automotive-grade designation. This part features the lowest input bias current (8 pA) and operates at the lowest minimum supply voltage (2.7V). However, it exhibits the lowest gain bandwidth product (3 MHz) and slew rate (1.5V/µs) among all alternatives. Moisture sensitivity level is MSL 3, requiring controlled storage conditions. This part is appropriate for automotive applications where AEC-Q100 qualification is mandatory.

Compliance and Certification:

All active substitute parts maintain ROHS3 compliance and REACH unaffected status. The OP284FSZ-REEL and ADA4084-2ARZ-RL maintain MSL 1 (unlimited moisture sensitivity), while OPA2172 variants carry MSL 2 (1 year) and OPA2171AQDRQ1 carries MSL 3 (168 hours), requiring appropriate handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the OP284FSZ-REEL be used as a direct replacement for the OP284FS-REEL?

A: Yes. The OP284FSZ-REEL is electrically and mechanically identical to the OP284FS-REEL, with the primary difference being active product status and ROHS3 compliance certification. Both parts share identical electrical specifications and 8-SOIC package footprint.

Q: What is the key difference between the OP284FS-REEL and the ADA4084-2ARZ-RL?

A: The ADA4084-2ARZ-RL provides enhanced performance with higher slew rate (4.6V/µs vs. 4V/µs), higher gain bandwidth product (15.9 MHz vs. 4.25 MHz), lower input offset voltage (30 µV vs. 175 µV), and higher output current per channel (30 mA vs. 10 mA). The maximum supply voltage is reduced to 30V. Both maintain the same 8-SOIC package and dual-circuit configuration.

Q: Are the OPA2172ID and OPA2172IDR electrically equivalent?

A: Yes. The OPA2172ID and OPA2172IDR are electrically identical, differing only in packaging format. The OPA2172ID is supplied in tube packaging, while the OPA2172IDR is supplied in cut tape and Digi-Reel format. Both feature 10V/µs slew rate and 10 MHz gain bandwidth product.

Q: What is the minimum supply voltage requirement for each substitute part?

A: OP284FS-REEL, OP284FSZ-REEL, and ADA4084-2ARZ-RL require 3V minimum. OPA2171AQDRQ1 requires 2.7V minimum. OPA2172ID and OPA2172IDR require 4.5V minimum. Applications operating below 4.5V cannot use the OPA2172 variants.

Q: Which substitute part is suitable for automotive applications?

A: The OPA2171AQDRQ1 is qualified to AEC-Q100 automotive standards and carries automotive-grade designation. This part is appropriate for automotive applications where AEC-Q100 qualification is mandatory.

Q: What are the moisture sensitivity level differences among substitute parts?

A: OP284FS-REEL and OP284FSZ-REEL carry MSL 1 (unlimited moisture sensitivity). ADA4084-2ARZ-RL carries MSL 1. OPA2172ID and OPA2172IDR carry MSL 2 (1 year shelf life). OPA2171AQDRQ1 carries MSL 3 (168 hours shelf life), requiring controlled storage conditions.

Q: Can the OPA2172 series be used in applications requiring operation below 4.5V?

A: No. The OPA2172ID and OPA2172IDR require a minimum supply voltage of 4.5V. Applications requiring operation at 3V supply voltage must use OP284FSZ-REEL, ADA4084-2ARZ-RL, or OPA2171AQDRQ1.

Q: What is the maximum supply voltage limitation for the ADA4084-2ARZ-RL?

A: The ADA4084-2ARZ-RL has a maximum supply voltage of 30V, compared to 36V for the OP284FS-REEL. Applications requiring operation above 30V cannot use the ADA4084-2ARZ-RL.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All substitute parts listed are housed in 8-SOIC (0.154", 3.90mm width) surface mount packages, ensuring mechanical compatibility with existing PCB designs.

Q: Which substitute part offers the highest output current per channel?

A: The OPA2172ID and OPA2172IDR offer the highest output current per channel at 75 mA, compared to 10 mA for the OP284FS-REEL and 30 mA for the ADA4084-2ARZ-RL.
