Key Parameters

Substitute Part Grouping Explanation

Substitution of the HA1-5320-5 is determined by electrical parameter equivalence and functional compatibility. The primary substitute identified is the HA9P5320-5Z, which 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 within the same temperature range (0°C to 75°C) and implement the same single-circuit sample and hold amplifier topology.

The key substitution criteria are:

• Amplifier Type: Sample and Hold (identical)
• Number of Circuits: 1 (identical)
• Slew Rate: 45 V/µs (identical)
• Gain Bandwidth Product: 2 MHz (identical)
• Current - Input Bias: 100 nA (identical)
• Voltage - Input Offset: 500 µV (identical)
• Current - Supply: 11 mA (identical)
• Current - Output / Channel: 10 mA (identical)
• Voltage - Supply Span: 27 V to 40 V (identical)
• Operating Temperature: 0°C to 75°C (identical)

The primary difference between the main part and substitute is the package configuration: the HA1-5320-5 uses a 14-CERDIP through-hole package, while the HA9P5320-5Z uses a 16-SOIC surface-mount package. This distinction requires evaluation of the target application's PCB layout and assembly capabilities.

Parameter Comparison

Engineering Selection Recommendations

The HA9P5320-5Z serves as the active production equivalent to the obsolete HA1-5320-5. All electrical performance parameters are identical, ensuring functional compatibility at the circuit level. The substitute part is currently in active production status with 2100 units available in inventory, compared to the obsolete main part with 1900 units remaining.

The HA9P5320-5Z carries ROHS3 compliance certification, whereas the HA1-5320-5 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements or customer specifications mandating RoHS-compliant components.

The primary consideration for substitution is the package transition from 14-CERDIP through-hole to 16-SOIC surface-mount. This change requires PCB redesign and assembly process modification. Applications utilizing through-hole assembly methods will require either PCB layout revision to accommodate surface-mount technology or identification of alternative through-hole packages if available.

The moisture sensitivity level increases from MSL 1 (unlimited) to MSL 3 (168 hours), requiring appropriate handling and storage protocols during manufacturing and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the HA9P5320-5Z directly replace the HA1-5320-5 in existing PCB designs?

A: Direct PCB replacement is not possible without layout modification. The HA1-5320-5 uses a 14-CERDIP through-hole package, while the HA9P5320-5Z uses a 16-SOIC surface-mount package. PCB redesign is required to accommodate the different package footprint and mounting technology.

Q: Are the electrical specifications identical between these two parts?

A: Yes. The HA9P5320-5Z maintains identical electrical performance across all specified parameters: slew rate (45 V/µs), gain bandwidth product (2 MHz), input bias current (100 nA), input offset voltage (500 µV), supply current (11 mA), output current (10 mA), and supply voltage range (27 V to 40 V). Operating temperature range is also identical (0°C to 75°C).

Q: What is the significance of the RoHS compliance difference?

A: The HA1-5320-5 is RoHS non-compliant, while the HA9P5320-5Z is ROHS3 compliant. Applications subject to RoHS regulations or customer specifications requiring RoHS-compliant components must use the HA9P5320-5Z. Non-regulated applications may use either part based on other selection criteria.

Q: How does the moisture sensitivity level difference affect component handling?

A: The HA1-5320-5 has MSL 1 (unlimited moisture sensitivity), allowing indefinite storage without moisture control. The HA9P5320-5Z has MSL 3 (168 hours), requiring controlled storage conditions and limiting the time the component can be exposed to ambient humidity before soldering. Manufacturing and assembly operations must implement appropriate moisture management protocols for the HA9P5320-5Z.

Q: What is the inventory status for each part?

A: The HA1-5320-5 (obsolete) has 1900 units available. The HA9P5320-5Z (active production) has 2100 units available. The active production status of the HA9P5320-5Z provides long-term availability assurance, whereas the obsolete HA1-5320-5 represents remaining stock only.

Q: Are there any pin configuration differences between the two packages?

A: The HA1-5320-5 is a 14-pin CERDIP package, while the HA9P5320-5Z is a 16-pin SOIC package. Pin count and configuration differ between the two packages. Detailed pinout documentation for each package must be consulted during PCB redesign to ensure correct signal routing and power distribution.
