Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA5232N/01,112 are selected based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Dual-circuit configuration (2 circuits per package)
• 8-DIP through-hole package format (0.300", 7.62mm)
• Rail-to-rail output capability
• Supply voltage range overlap (minimum 2V to 5.5V operation)
• General purpose amplifier classification

Substitution Logic: The MCP6242-E/P and OPA2337PA both satisfy the core package and functional requirements. Both devices feature dual op-amp circuits in 8-DIP packages with rail-to-rail outputs. However, they differ in electrical performance characteristics including slew rate, input bias current, supply current consumption, and temperature operating range. These differences determine suitability for specific application requirements while maintaining pin-compatible replacement capability.

Parameter Comparison

Engineering Selection Recommendations

MCP6242-E/P Selection Criteria: The MCP6242-E/P is an active product from Microchip Technology with ROHS3 compliance. This substitute provides extended temperature operation (-40°C to 125°C) compared to the SA5232N/01,112. The MCP6242-E/P features significantly lower supply current consumption (50 µA versus 1.4 mA), making it suitable for battery-powered and low-power applications. Higher output current capability (23 mA per channel) supports applications requiring greater load drive. The lower slew rate (0.3 V/µs) and reduced input bias current (1 pA) indicate improved precision characteristics. Pin-compatible 8-DIP package enables direct board-level replacement.

OPA2337PA Selection Criteria: The OPA2337PA is an active CMOS amplifier from Burr Brown, classified within the MicroAmplifier™ series. This substitute maintains the same operating temperature range as the original (-40°C to 85°C). The OPA2337PA offers the highest slew rate (1.2 V/µs) among the three options, supporting faster signal processing applications. Input bias current is extremely low (0.2 pA), providing superior precision for high-impedance input circuits. Supply current consumption (525 µA) falls between the SA5232N/01,112 and MCP6242-E/P. Pin-compatible 8-DIP package enables direct replacement. Output current per channel (9 mA) is lower than both alternatives.

Compliance Considerations: Both substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original device. Selection between MCP6242-E/P and OPA2337PA depends on specific application requirements regarding power consumption, slew rate, and temperature operating range rather than regulatory or compliance factors.

Frequently Asked Questions (FAQ)

Q: Are MCP6242-E/P and OPA2337PA pin-compatible replacements for SA5232N/01,112?

A: Both devices are pin-compatible replacements in 8-DIP through-hole packages. The dual op-amp configuration and pin assignments support direct board-level substitution without PCB modifications.

Q: What is the primary reason for substituting the SA5232N/01,112?

A: The SA5232N/01,112 is classified as obsolete. MCP6242-E/P and OPA2337PA are active products with ongoing manufacturing and supply availability, ensuring production continuity and long-term component sourcing.

Q: How do supply current requirements differ between these devices?

A: The SA5232N/01,112 draws 1.4 mA across both channels. The MCP6242-E/P consumes significantly less at 50 µA, suitable for ultra-low-power applications. The OPA2337PA draws 525 µA, representing a middle ground between the two.

Q: Which substitute offers the best high-frequency performance?

A: The OPA2337PA provides the highest slew rate at 1.2 V/µs, compared to 0.8 V/µs for the original and 0.3 V/µs for the MCP6242-E/P. Slew rate determines the maximum rate of output voltage change, affecting performance in high-frequency signal processing applications.

Q: What are the input bias current differences, and why do they matter?

A: The SA5232N/01,112 has 25 nA input bias current. The MCP6242-E/P reduces this to 1 pA, and the OPA2337PA to 0.2 pA. Lower input bias current is critical for high-impedance input circuits, precision instrumentation, and applications where input loading must be minimized.

Q: Can OPA2337PA replace SA5232N/01,112 in all temperature ranges?

A: The OPA2337PA operates from -40°C to 85°C, matching the original device's temperature range. The MCP6242-E/P extends operation to 125°C, providing additional thermal margin for high-temperature environments.

Q: What output current capability should I consider for my application?

A: The SA5232N/01,112 provides 12 mA per channel. The MCP6242-E/P offers 23 mA per channel for higher load drive capability. The OPA2337PA provides 9 mA per channel. Select based on your specific load impedance and current requirements.

Q: Are there any supply voltage range limitations when substituting?

A: The SA5232N/01,112 operates from 2V to 5.5V. The MCP6242-E/P extends the minimum to 1.8V, enabling operation in lower-voltage systems. The OPA2337PA requires a minimum of 2.7V, which may limit use in 2V-only applications. Verify your supply voltage compatibility before selection.
