Engineering Selection Recommendations

OP484ESZ-REEL is the primary direct substitute for OP484ES-REEL. Both parts share identical electrical specifications, package configuration (14-SOIC), and thermal operating range (-40°C to 125°C). OP484ESZ-REEL maintains active product status with ROHS3 compliance and significantly higher inventory availability (27,269 units versus 688 units). This part provides drop-in compatibility with no design modifications required.

ADA4084-4ARUZ-RL serves as a performance-enhanced alternative with improved specifications including higher slew rate (4.6 V/µs), superior gain bandwidth product (15.9 MHz), lower input offset voltage (60 µV), and increased output current capability (30 mA per channel). The package differs as 14-TSSOP, requiring PCB layout modification. Supply voltage maximum is reduced to 30 V. This part is suitable for applications requiring higher bandwidth and output drive capability.

LT1496HS#PBF and LT1496IS#PBF represent low-power alternatives with significantly reduced slew rate (0.001 V/µs) and gain bandwidth product (2.7 kHz). These parts feature extremely low input bias current (250 pA) and supply current (1 µA per channel). LT1496HS#PBF supports full temperature range (-40°C to 125°C), while LT1496IS#PBF operates to 85°C maximum. These substitutes are applicable only to applications where bandwidth and slew rate requirements are substantially lower than the original specification.

OPA4171AQDRQ1 is a Texas Instruments alternative with automotive-grade qualification (AEC-Q100) and active product status. This part features exceptionally low input bias current (8 pA), moderate slew rate (1.5 V/µs), and higher output current capability (35 mA per channel). Minimum supply voltage is 4.5 V, restricting use in 3 V supply applications. This part is suitable for automotive and industrial applications requiring AEC-Q100 qualification.

Frequently Asked Questions (FAQ)

Q: Can OP484ESZ-REEL directly replace OP484ES-REEL without design changes?

A: Yes. OP484ESZ-REEL is a direct substitute with identical electrical specifications, package configuration, and thermal operating range. No PCB modifications or design changes are required.

Q: What is the primary difference between OP484ES-REEL and ADA4084-4ARUZ-RL?

A: The primary differences are package type (14-SOIC versus 14-TSSOP), slew rate (4 V/µs versus 4.6 V/µs), gain bandwidth product (4.25 MHz versus 15.9 MHz), and maximum supply voltage (36 V versus 30 V). ADA4084-4ARUZ-RL requires PCB layout modification due to different package footprint.

Q: Are LT1496 series parts suitable replacements for OP484ES-REEL?

A: LT1496 series parts are functionally compatible only in applications where significantly lower bandwidth is acceptable. These parts have slew rate of 0.001 V/µs and gain bandwidth product of 2.7 kHz, compared to 4 V/µs and 4.25 MHz for OP484ES-REEL. They are not suitable for applications requiring the original bandwidth performance.

Q: What is the advantage of OPA4171AQDRQ1 over OP484ES-REEL?

A: OPA4171AQDRQ1 offers automotive-grade qualification (AEC-Q100), exceptionally low input bias current (8 pA), and higher output current capability (35 mA per channel). The minimum supply voltage requirement is 4.5 V, which restricts use in 3 V supply applications.

Q: Can I use a 14-TSSOP package part in place of a 14-SOIC package part?

A: No. While 14-TSSOP and 14-SOIC packages have different physical dimensions and pin spacing, they are not mechanically interchangeable. PCB layout and footprint modifications are required when substituting between these package types.

Q: Which substitute part has the best availability?

A: OPA4171AQDRQ1 has the highest inventory availability at 27,800 units. OP484ESZ-REEL has 27,269 units in stock. Both parts are readily available compared to the original OP484ES-REEL with 688 units.

Q: Is OP484ESZ-REEL still in active production?

A: Yes. OP484ESZ-REEL maintains active product status, whereas OP484ES-REEL is classified as obsolete. OP484ESZ-REEL is the recommended replacement for long-term design continuity.

Q: What are the compliance differences between substitute parts?

A: OP484ESZ-REEL, ADA4084-4ARUZ-RL, LT1496 series, and OPA4171AQDRQ1 all maintain ROHS3 compliance and REACH unaffected status. OPA4171AQDRQ1 additionally carries AEC-Q100 automotive qualification. All parts have moisture sensitivity level 1 or 3 as specified.

Q: Can I use OPA4171AQDRQ1 in a 3 V supply application?

A: No. OPA4171AQDRQ1 requires a minimum supply voltage of 4.5 V. Applications requiring 3 V operation must use OP484ESZ-REEL, ADA4084-4ARUZ-RL, or LT1496 series parts.

Q: What is the temperature range limitation of LT1496IS#PBF?

A: LT1496IS#PBF operates from -40°C to 85°C maximum, compared to -40°C to 125°C for OP484ES-REEL. Applications requiring operation above 85°C must use LT1496HS#PBF, OP484ESZ-REEL, ADA4084-4ARUZ-RL, or OPA4171AQDRQ1.
