Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA5534N is determined by electrical and mechanical compatibility across the following critical parameters: package type (8-DIP through-hole), number of circuits (1), mounting configuration, supply voltage range, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current capability. Substitute parts must maintain functional equivalence within the operational temperature range and support the same signal processing characteristics.

The substitute parts are grouped into two categories based on amplifier type and electrical performance:

Category 1: General Purpose Amplifiers (Electrical Equivalents) Parts SA5534AP, SA5534P, and NE5534P maintain identical electrical specifications to the SA5534N, including slew rate (13 V/µs), gain bandwidth product (10 MHz), input bias current (500 nA), and input offset voltage (500 µV). These parts differ in manufacturer, product status, and supply voltage range constraints.

Category 2: J-FET Amplifier (Enhanced Performance) Part AD845KNZ is a J-FET amplifier offering superior electrical performance with higher slew rate (100 V/µs), higher gain bandwidth product (16 MHz), and lower input bias current (500 pA). This part operates within a narrower supply voltage range (9.5 V to 36 V) and restricted operating temperature range (0°C to 70°C).

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalence: SA5534AP and SA5534P are direct electrical equivalents to the SA5534N, maintaining identical slew rate, gain bandwidth product, input bias current, and input offset voltage specifications. Both parts are manufactured by Texas Instruments and carry ROHS3 compliance status. SA5534AP supports the full operating temperature range (-40°C to 85°C) matching the SA5534N, while SA5534P also supports this range. Both parts are classified as Last Time Buy, indicating limited future availability.

NE5534P, also manufactured by Texas Instruments, provides electrical equivalence with identical performance parameters. This part operates within a narrower temperature range (0°C to 70°C) and is classified as Last Time Buy.

For Enhanced Performance with Compliance: AD845KNZ is an active product manufactured by Analog Devices Inc. with ROHS3 compliance. This J-FET amplifier offers superior electrical performance including higher slew rate (100 V/µs), higher gain bandwidth product (16 MHz), lower input bias current (500 pA), and lower input offset voltage (100 µV). The AD845KNZ operates within a narrower supply voltage range (9.5 V to 36 V) and restricted temperature range (0°C to 70°C), requiring circuit design verification for compatibility.

Compliance Considerations: All substitute parts except SA5534N are ROHS3 compliant. For applications requiring RoHS compliance, SA5534AP, SA5534P, NE5534P, or AD845KNZ are suitable selections. The SA5534N remains available for legacy system support where RoHS non-compliance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can SA5534AP directly replace SA5534N in existing designs? A: SA5534AP provides direct electrical equivalence with identical slew rate (13 V/µs), gain bandwidth product (10 MHz), input bias current (500 nA), and input offset voltage (500 µV). Both parts use the same 8-DIP package and through-hole mounting. SA5534AP supports the full operating temperature range (-40°C to 85°C). Direct substitution is supported from an electrical and mechanical standpoint.

Q: What are the key differences between SA5534P and NE5534P? A: SA5534P and NE5534P are electrically identical, both providing 13 V/µs slew rate and 10 MHz gain bandwidth product. Both are manufactured by Texas Instruments and use the 8-DIP package. The primary difference is manufacturer designation and product status classification. Both are Last Time Buy products with limited availability.

Q: Is AD845KNZ a suitable replacement for SA5534N? A: AD845KNZ is mechanically compatible (8-DIP package, through-hole mounting) but differs in amplifier type (J-FET versus general purpose) and electrical performance. AD845KNZ offers higher slew rate (100 V/µs versus 13 V/µs), higher gain bandwidth product (16 MHz versus 10 MHz), and lower input bias current (500 pA versus 500 nA). The supply voltage range is narrower (9.5 V to 36 V versus 6 V to 40 V) and operating temperature is restricted (0°C to 70°C versus -40°C to 85°C). Substitution requires circuit design verification to confirm compatibility with the enhanced performance characteristics.

Q: What is the supply voltage compatibility between SA5534N and substitute parts? A: SA5534N operates from 6 V to 40 V. SA5534AP and SA5534P operate from 10 V to 30 V, requiring minimum supply voltage of 10 V. NE5534P operates from 10 V to 30 V. AD845KNZ operates from 9.5 V to 36 V. For applications using supply voltages below 10 V or above 36 V, SA5534N remains the only option among these parts.

Q: Are all substitute parts available in the same packaging? A: All substitute parts use the 8-DIP (0.300", 7.62mm) package with through-hole mounting, matching the SA5534N package configuration. Packaging differences exist only in supplier delivery format (tube versus other formats), which does not affect circuit board compatibility.

Q: What is the product status significance for long-term availability? A: SA5534N is classified as Obsolete, indicating no further production. SA5534AP, SA5534P, and NE5534P are classified as Last Time Buy, indicating limited production windows before discontinuation. AD845KNZ is classified as Active, indicating ongoing production and long-term availability. For new designs requiring extended component availability, AD845KNZ is the recommended selection.

Q: How do input bias current specifications affect circuit design? A: SA5534N, SA5534AP, SA5534P, and NE5534P all specify 500 nA input bias current. AD845KNZ specifies 500 pA input bias current, which is 1000 times lower. Lower input bias current reduces input offset current errors and is beneficial for high-impedance input circuits. Circuits designed for 500 nA bias current operate correctly with 500 pA bias current, but the reverse is not guaranteed.

Q: What compliance certifications apply to substitute parts? A: SA5534N is RoHS non-compliant. SA5534AP, SA5534P, NE5534P, and AD845KNZ are all ROHS3 compliant. All parts are REACH unaffected and classified under ECCN EAR99. For applications requiring RoHS compliance, any substitute part except SA5534N is suitable.
