Substitute Part Grouping Explanation

Substitution for the SN74HC32NG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: OR Gate (4-channel, 2-input configuration)
• Voltage Supply Range: 2V ~ 6V
• Current Specifications: Quiescent current 2 µA maximum; output current 5.2mA for both high and low states
• Propagation Delay: 17ns maximum at 6V with 50pF load
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 14-DIP through-hole mounting
• Compliance: ROHS3 compliant, REACH unaffected

The SN74HC32N qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary distinction is product status and packaging format, not electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC32N is the direct equivalent for the discontinued SN74HC32NG4. Both parts maintain identical electrical specifications, functional performance, and compliance certifications. The SN74HC32N is currently active in production and available in higher inventory quantities, making it the appropriate selection for new designs and replacement procurement.

Both parts satisfy ROHS3 compliance requirements and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications. The through-hole 14-DIP package format is consistent across both parts, eliminating any PCB layout or assembly modifications.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC32N directly replace the SN74HC32NG4 without circuit modifications?

A: Yes. The SN74HC32N is electrically and functionally identical to the SN74HC32NG4. All electrical parameters, including supply voltage range, propagation delay, output current, and operating temperature, are equivalent. The 14-DIP package footprint is identical, requiring no PCB layout changes.

Q: What is the primary difference between these two part numbers?

A: The SN74HC32NG4 is discontinued at DiGi Electronics, while the SN74HC32N maintains active production status. The packaging format differs (NG4 versus N designation), but electrical specifications remain unchanged.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory and environmental compliance is equivalent across both parts.

Q: What inventory considerations apply to this substitution?

A: The SN74HC32NG4 has 1,013 pieces available as new original stock. The SN74HC32N has 20,400 pieces available, providing greater supply availability for ongoing procurement needs.

Q: Is the 14-DIP package suitable for my application?

A: The 14-DIP package is a through-hole component with 0.300-inch (7.62mm) pin spacing. Confirm your PCB design accommodates through-hole mounting before component selection. Both substitute parts use identical package specifications.
