OPA552PA Equivalent & Substitute Parts

Part Overview

The OPA552PA is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This device is classified as obsolete, indicating that it is no longer in active production. The OPA552PA delivers a slew rate of 24V/µs with a gain bandwidth product of 12 MHz, making it suitable for general-purpose amplification applications requiring moderate bandwidth and slew rate performance. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity, system maintenance, and component procurement in legacy and new applications requiring compatible performance characteristics.

Substitute Part Grouping Explanation

Substitution of the OPA552PA is determined by electrical and mechanical parameter equivalence within the OPA552 base product family. The substitute part OPA552FA/500 maintains identical electrical specifications across all critical performance parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range. Both devices operate across the same temperature range (-40°C to 125°C) and share the same base product number (OPA552), confirming functional equivalence.

The primary distinction between the OPA552PA and OPA552FA/500 lies in packaging and mounting technology. The OPA552PA utilizes through-hole mounting in an 8-DIP package, while the OPA552FA/500 employs surface-mount technology in a TO-263 (DDPAK-7) package. This packaging difference necessitates circuit board redesign and assembly process modification but does not affect electrical performance or functional compatibility.

Key Parameters Determining Substitution:

• Slew Rate: 24 V/µs (identical)
• Gain Bandwidth Product: 12 MHz (identical)
• Current - Input Bias: 20 pA (identical)
• Voltage - Input Offset: 1 mV (identical)
• Current - Supply: 7 mA (identical)
• Current - Output / Channel: 200 mA (identical)
• Voltage - Supply Span: 8 V to 60 V (identical)
• Operating Temperature: -40°C to 125°C (identical)

Parameter Comparison

Engineering Selection Recommendations

The OPA552FA/500 is the manufacturer-recommended substitute for the obsolete OPA552PA. Both devices are manufactured by Texas Instruments and share identical electrical performance specifications, ensuring functional compatibility in circuit applications. The OPA552FA/500 maintains active product status, providing assured long-term availability and supply chain continuity compared to the obsolete OPA552PA.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements. The ECCN classification (EAR99) and HTSUS code (8542.33.0001) are identical, confirming equivalent export and tariff treatment.

Selection between these parts depends on circuit board design constraints and manufacturing capabilities. The OPA552PA through-hole package suits legacy through-hole assembly processes and breadboard prototyping. The OPA552FA/500 surface-mount package accommodates modern surface-mount technology (SMT) manufacturing and enables higher-density circuit board layouts. The OPA552FA/500 exhibits a higher moisture sensitivity level (MSL 2, 1 Year) compared to the OPA552PA (MSL 1, Unlimited), requiring appropriate storage and handling protocols during manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the OPA552FA/500 directly replace the OPA552PA in existing circuit designs?

A: Electrical substitution is complete; the OPA552FA/500 delivers identical performance across all specified electrical parameters. However, direct physical replacement requires circuit board redesign due to package differences. The OPA552PA uses an 8-DIP through-hole package, while the OPA552FA/500 uses a TO-263 surface-mount package. Pin configurations differ, necessitating layout modifications and assembly process changes.

Q: What are the key electrical parameters that confirm substitution compatibility?

A: The OPA552PA and OPA552FA/500 share identical specifications for slew rate (24 V/µs), gain bandwidth product (12 MHz), input bias current (20 pA), input offset voltage (1 mV), supply current (7 mA), output current per channel (200 mA), and supply voltage range (8 V to 60 V). Operating temperature range (-40°C to 125°C) is also identical. These parameters define the functional equivalence between the two devices.

Q: Why is the OPA552PA classified as obsolete?

A: The OPA552PA is no longer manufactured by Texas Instruments. The OPA552FA/500 represents the active product continuation within the OPA552 family, offering equivalent electrical performance in a modern surface-mount package format.

Q: What is the significance of the different moisture sensitivity levels?

A: The OPA552PA carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The OPA552FA/500 carries MSL 2 (1 Year), requiring controlled storage conditions and limiting shelf life to one year from the date of manufacture. Manufacturing facilities must implement appropriate moisture control protocols when handling the OPA552FA/500 to prevent moisture absorption that could compromise device reliability.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, EAR99 export classification, and HTSUS code 8542.33.0001. No regulatory or compliance barriers exist to substitution.

Q: What packaging options are available for the OPA552 family?

A: The OPA552PA is available in 8-DIP through-hole packaging. The OPA552FA/500 is available in TO-263 (DDPAK-7) surface-mount packaging. Both represent the complete OPA552 family offerings for these specific package types.
