Substitute Part Grouping Explanation

Substitution for the SN74F02NG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: NOR Gate (4 channels, 2 inputs per channel)
• Electrical Specifications: 4.5V ~ 5.5V supply voltage, 1mA/20mA output current, 5.5ns propagation delay
• Package Configuration: 14-DIP through-hole mounting
• Input/Output Logic Levels: 0.8V low threshold, 2V high threshold
• Operating Temperature Range: 0°C ~ 70°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The SN74F02N meets all these criteria and serves as a direct functional equivalent. Substitution is valid when all electrical and mechanical parameters align with these specifications.

Parameter Comparison

Engineering Selection Recommendations

The SN74F02N is the appropriate substitute for the SN74F02NG4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The SN74F02N maintains active product status, ensuring availability for current and future production requirements. Both parts comply with ROHS3 standards and REACH regulations, meeting environmental and regulatory compliance requirements. The primary distinction is product availability: the SN74F02NG4 is discontinued, while the SN74F02N remains in active production with documented inventory.

Frequently Asked Questions (FAQ)

Q: Can the SN74F02N directly replace the SN74F02NG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The SN74F02N operates within the same voltage range (4.5V ~ 5.5V), maintains identical propagation delay (5.5ns @ 5V, 50pF), and uses the same 14-DIP through-hole package. Pin-for-pin compatibility is confirmed.

Q: What is the difference between SN74F02NG4 and SN74F02N?

A: The primary difference is product status and packaging designation. The SN74F02NG4 is discontinued, while the SN74F02N is active. Both share identical electrical specifications, logic configuration (4-channel NOR gate, 2 inputs per channel), and 14-DIP packaging.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected. Regulatory and environmental compliance requirements are equivalent.

Q: What parameters must match for a valid substitution?

A: Critical parameters include logic type (NOR Gate), circuit count (4 channels), input count (2 per channel), supply voltage range (4.5V ~ 5.5V), output current specifications (1mA/20mA), propagation delay (5.5ns), operating temperature range (0°C ~ 70°C), and package type (14-DIP through-hole).

Q: Is the SN74F02N available in the same packaging options?

A: The SN74F02N is supplied in Tube packaging, while the SN74F02NG4 packaging designation differs. Both use the 14-DIP (0.300", 7.62mm) physical package configuration suitable for through-hole mounting.
