Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KA5532 are evaluated based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Dual-channel amplifier configuration (2 circuits)
• 8-DIP through-hole package format (0.300", 7.62mm)
• Gain bandwidth product of 10 MHz
• Input bias current of 200 nA
• Input offset voltage of 500 µV
• Output current per channel of 38 mA
• Operating temperature range of 0°C to 70°C

Substitution Logic:

Parts meeting all primary criteria are classified as direct functional equivalents. The NE5532P, NE5532AP, and SA5532P devices satisfy all key electrical and mechanical parameters, making them suitable direct replacements for the obsolete KA5532.

The LM258P operates within the same 8-DIP package but exhibits reduced performance specifications (slew rate of 0.3 V/µs versus 8 V/µs, gain bandwidth product of 700 kHz versus 10 MHz, and lower supply voltage span). This device functions as a lower-performance alternative suitable only for applications with relaxed bandwidth and slew rate requirements.

The TLE2082ACP provides a J-FET amplifier topology with enhanced slew rate (40 V/µs) and significantly lower input bias current (20 pA), representing a higher-performance alternative for applications requiring superior input impedance and transient response characteristics.

Engineering Selection Recommendations

Direct Functional Equivalents (Recommended Primary Substitutes):

The NE5532P and NE5532AP operational amplifiers are the preferred substitutes for the obsolete KA5532. Both devices are manufactured by Texas Instruments and maintain active product status with ROHS3 compliance. These parts satisfy all critical electrical parameters including 10 MHz gain bandwidth product, 9 V/µs slew rate, 200 nA input bias current, and 500 µV input offset voltage. The NE5532P is available in higher inventory (25,300 units) compared to NE5532AP (3,497 units), providing superior supply chain availability.

The SA5532P and SA5532AP devices provide equivalent electrical performance with extended operating temperature ranges (-40°C to 85°C), offering enhanced thermal capability for applications requiring operation beyond the standard 0°C to 70°C specification. Both variants maintain ROHS3 compliance and active product status.

Lower-Performance Alternative:

The LM258P operates as a reduced-specification substitute suitable only for applications where bandwidth and slew rate requirements are significantly relaxed. This device exhibits 700 kHz gain bandwidth product and 0.3 V/µs slew rate, representing approximately 14-fold reduction in bandwidth and 27-fold reduction in slew rate compared to the KA5532. The LM258P provides superior supply voltage flexibility (3 V to 32 V) and lower input bias current (20 nA), making it suitable for low-power and single-supply applications. ROHS3 compliance and active product status support long-term availability.

Higher-Performance Alternative:

The TLE2082ACP J-FET amplifier provides enhanced performance characteristics including 40 V/µs slew rate and 20 pA input bias current, suitable for applications requiring superior transient response and input impedance. This device maintains 10 MHz gain bandwidth product and ROHS3 compliance. The J-FET topology introduces different input offset voltage characteristics (700 µV) and requires evaluation for offset-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the LM258P directly replace the KA5532 in all applications?

A: The LM258P operates as a functional substitute only for applications with relaxed bandwidth and slew rate requirements. The LM258P provides 700 kHz gain bandwidth product and 0.3 V/µs slew rate compared to the KA5532 specification of 10 MHz and 8 V/µs. Applications requiring the full 10 MHz bandwidth and 8 V/µs slew rate performance must use NE5532P, NE5532AP, SA5532P, or SA5532AP devices.

Q: What is the primary difference between NE5532P and SA5532P?

A: Both devices provide identical electrical performance specifications. The SA5532P and SA5532AP variants extend the operating temperature range to -40°C to 85°C compared to the standard 0°C to 70°C range of NE5532P and NE5532AP. Selection between these families depends on application temperature requirements.

Q: Is the TLE2082ACP suitable as a direct replacement for the KA5532?

A: The TLE2082ACP provides equivalent package format and 10 MHz gain bandwidth product but operates as a J-FET amplifier topology rather than a general-purpose bipolar design. The TLE2082ACP exhibits significantly different input bias current (20 pA versus 200 nA) and slew rate (40 V/µs versus 8 V/µs). This device functions as a higher-performance alternative for applications requiring superior input impedance and transient response, but circuit redesign evaluation is necessary for offset-sensitive applications due to different input offset voltage characteristics.

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

A: All substitute parts listed operate in the 8-DIP (0.300", 7.62mm) through-hole package format, providing direct mechanical compatibility with KA5532 circuit board layouts. No PCB modifications are required for package accommodation.

Q: What compliance certifications apply to substitute parts?

A: All active substitute parts (NE5532P, NE5532AP, SA5532P, SA5532AP, LM258P, and TLE2082ACP) maintain ROHS3 compliance and REACH unaffected status. These certifications support integration into modern manufacturing environments and regulatory compliance requirements.

Q: Which substitute part offers the best supply chain availability?

A: The NE5532P maintains the highest inventory level at 25,300 units, followed by LM258P at 34,988 units. For applications requiring the full 10 MHz bandwidth and 8 V/µs slew rate performance of the KA5532, the NE5532P provides optimal supply chain continuity.
