Substitute Part Grouping Explanation

Substitution of the SN7432NG4 is determined by strict equivalence across the following critical parameters:

  • Logic type and function: 4-channel OR gate with 2 inputs per channel
  • Electrical specifications: Supply voltage 4.75V ~ 5.25V, output current 800µA/16mA, propagation delay 22ns @ 5V/15pF
  • Input logic levels: Low 0.8V, High 2V
  • Operating temperature range: 0°C ~ 70°C
  • Package type: 14-DIP through-hole mounting
  • Series classification: 7400 logic family
  • Compliance standards: ROHS3 compliant, REACH unaffected

The SN7432N qualifies as a direct substitute based on identical electrical characteristics, logic configuration, and package specifications. The primary distinction is product status and packaging format.

The SN7432N carries active product status, ensuring continued availability and supply chain reliability. Both parts meet ROHS3 compliance and REACH unaffected standards, supporting regulatory requirements for modern electronics manufacturing. Selection of the SN7432N eliminates obsolescence risk while preserving full functional and electrical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the SN7432N directly replace the SN7432NG4 in existing circuit designs?

A: Yes. The SN7432N provides identical electrical specifications, logic configuration, and 14-DIP package dimensions. No circuit modifications are required for direct substitution.

Q: What is the primary reason for substitution?

A: The SN7432NG4 is discontinued at DiGi Electronics. The SN7432N maintains active product status and is the manufacturer-recommended equivalent.

Q: Are there differences in packaging or handling?

A: The SN7432NG4 uses standard packaging, while the SN7432N is supplied in tube packaging. Both use identical 14-DIP through-hole package specifications. Moisture sensitivity levels differ (SN7432NG4: MSL 1 Unlimited; SN7432N: Not Applicable), but both are suitable for standard handling and storage conditions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SN7432NG4 and SN7432N are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Are the electrical performance characteristics identical?

A: Yes. Supply voltage, output current, input logic levels, propagation delay, and operating temperature range are identical across both parts.
