Engineering Selection Recommendations

Direct Replacement (Recommended for Obsolete Part Mitigation):

OP492GSZ-REEL is the direct equivalent of OP492GS-REEL. This part maintains identical electrical specifications and mechanical packaging while offering active product status. The primary distinction is packaging format (Tape & Reel vs. standard reel configuration) and RoHS3 compliance certification. This part is the preferred choice for direct substitution in existing designs.

General Purpose Amplifier Alternatives:

MC33074ADR2G, MC33074DR2G, MC33179DR2G, and MC34074ADR2G (onsemi) are general purpose four-circuit amplifiers in 14-SOIC packages with active product status and RoHS3 compliance. These parts operate within the OP492GS-REEL supply voltage range and maintain the same circuit count and package footprint. MC33074 variants offer higher slew rates (13 V/µs) and improved gain bandwidth product (4.5 MHz) compared to the original part. MC33179DR2G provides enhanced output current capability (100 mA per channel) and lower input offset voltage (150 µV). Operating temperature ranges vary; MC33074ADR2G and MC33179DR2G support -40°C to 85°C, while MC34074ADR2G is rated 0°C to 70°C.

BA2902YF-CE2 (Rohm Semiconductor) is a general purpose four-circuit amplifier with automotive qualification (AEC-Q100) and active product status. This part operates within an extended supply voltage range (3 V to 36 V) and features push-pull output configuration. However, it exhibits significantly lower slew rate (0.2 V/µs) and reduced gain bandwidth product (500 kHz) relative to the OP492GS-REEL.

J-FET Amplifier Alternatives:

LF247DT, LF347D, and LF347DT (STMicroelectronics) and OPA4131NA (Texas Instruments) are J-FET input amplifiers with four circuits in 14-SOIC packages and active product status. These parts feature extremely low input bias current (20 pA for STMicroelectronics; 5 pA for Texas Instruments) and higher slew rates (10-16 V/µs) compared to the OP492GS-REEL. However, they require higher minimum supply voltages (9 V for OPA4131NA; 44 V for LF247DT and LF347 variants). Operating temperature ranges are more restricted: LF347D and LF347DT are rated 0°C to 70°C; LF247DT is rated -40°C to 105°C; OPA4131NA is rated -40°C to 85°C. All J-FET alternatives carry RoHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can OP492GSZ-REEL be used as a direct replacement for OP492GS-REEL?

A: Yes. OP492GSZ-REEL is electrically and mechanically identical to OP492GS-REEL. Both parts contain four general purpose amplifier circuits with identical slew rate (4 V/µs), gain bandwidth product (4 MHz), input bias current (375 nA), and supply voltage range (4.5 V to 33 V). The primary difference is product status: OP492GSZ-REEL is active with RoHS3 compliance, while OP492GS-REEL is obsolete. Packaging format differs (Tape & Reel vs. standard reel), but pinout and electrical performance are equivalent.

Q: What are the key differences between general purpose and J-FET amplifier alternatives?

A: General purpose amplifiers (MC33074, MC33179, BA2902) use bipolar input stages and are optimized for standard applications with moderate input impedance requirements. J-FET amplifiers (LF247, LF347, OPA4131) feature J-FET input stages providing extremely low input bias current (5-20 pA vs. 100-375 nA) and higher input impedance, making them suitable for high-impedance signal sources. J-FET alternatives exhibit higher slew rates (10-16 V/µs) but require higher minimum supply voltages (9-44 V) compared to the OP492GS-REEL (4.5 V minimum).

Q: Are all substitute parts available in 14-SOIC packaging?

A: All substitute parts listed are available in 14-SOIC or equivalent 14-pin surface mount packages (14-SOP, 14-SO). Package dimensions are consistent at 0.154" to 0.173" width, ensuring PCB footprint compatibility. BA2902YF-CE2 uses 14-SOP packaging with slightly larger width (4.40mm vs. 3.90mm), which may require PCB layout verification for tight spacing applications.

Q: Which substitute parts support the full -40°C to 125°C operating temperature range of the OP492GS-REEL?

A: Only BA2902YF-CE2 (Rohm Semiconductor) supports the complete -40°C to 125°C temperature range among the listed alternatives. OP492GSZ-REEL maintains this range as the direct equivalent. Other alternatives have more restricted temperature ranges: MC33074 and MC33179 variants support -40°C to 85°C; LF347D and LF347DT support 0°C to 70°C; OPA4131NA supports -40°C to 85°C.

Q: What is the supply voltage compatibility of substitute parts?

A: The OP492GS-REEL operates from 4.5 V to 33 V. OP492GSZ-REEL maintains this range. MC33074, MC33179, and MC34074 variants operate from 3 V to 44 V, providing broader compatibility. BA2902YF-CE2 operates from 3 V to 36 V. J-FET alternatives (LF247, LF347, OPA4131) require higher minimum voltages: LF247 and LF347 require 44 V fixed supply; OPA4131NA requires 9 V minimum to 36 V maximum. Design verification is required if the original circuit operates below 9 V.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification. OP492GSZ-REEL, BA2902YF-CE2, LF247DT, LF347D, LF347DT, MC33074ADR2G, MC33074DR2G, MC33179DR2G, MC34074ADR2G, and OPA4131NA all meet RoHS3 requirements. REACH status is unaffected for all alternatives.

Q: Which substitute offers the highest output current capability?

A: MC33179DR2G provides the highest output current per channel at 100 mA, compared to 10.5 mA for the OP492GS-REEL. This makes MC33179DR2G suitable for applications requiring higher load driving capability. Other alternatives provide intermediate output current: LF247DT and LF347 variants offer 40 mA; MC33074 variants offer 30 mA; OPA4131NA offers 25 mA.

Q: What is the moisture sensitivity level (MSL) of substitute parts?

A: OP492GSZ-REEL, BA2902YF-CE2, LF247DT, LF347D, LF347DT, MC33074ADR2G, MC33074DR2G, MC33179DR2G, and MC34074ADR2G all carry MSL 1 (Unlimited), matching the OP492GS-REEL. OPA4131NA carries MSL 3 (168 Hours), indicating more stringent moisture handling requirements during storage and assembly.
