Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F02PC is determined by strict equivalence across the following parameters:

• Logic Function: Identical NOR gate configuration (4 channels, 2 inputs per channel)
• Electrical Characteristics: Matching voltage supply range (4.5V ~ 5.5V), output current ratings (1mA/20mA), input logic levels (0.8V low, 2V high), and propagation delay (5.5ns @ 5V, 50pF)
• Package Compatibility: 14-DIP through-hole mounting with 0.300" (7.62mm) pitch
• Series Designation: 74F logic family

The SN74F02N from Texas Instruments meets all substitution criteria. Both parts share identical functional specifications, electrical performance, and physical packaging, enabling direct pin-for-pin replacement.

Engineering Selection Recommendations

The SN74F02N is the direct functional equivalent for the obsolete 74F02PC. Selection is based on:

• Product Status: The SN74F02N maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 74F02PC.
• Regulatory Compliance: The SN74F02N is ROHS3 compliant, meeting current environmental and material restriction standards. Both parts maintain REACH Unaffected status.
• Electrical Equivalence: All functional and electrical parameters are identical, enabling direct substitution without circuit redesign.
• Physical Compatibility: Both parts use identical 14-DIP through-hole packaging, allowing direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74F02N replace the 74F02PC in existing designs?

A: Yes. The SN74F02N is a direct pin-for-pin equivalent with identical electrical specifications, logic function, and package dimensions. No circuit modifications are required.

Q: Are there differences in packaging between these parts?

A: Both parts use 14-DIP (0.300", 7.62mm) through-hole packaging. The primary difference is packaging format: the 74F02PC uses MDIP while the SN74F02N uses PDIP. Both are compatible with standard 14-DIP PCB footprints.

Q: What is the significance of the product status difference?

A: The 74F02PC is obsolete, indicating onsemi has discontinued production. The SN74F02N is active, meaning Texas Instruments continues manufacturing and supporting this part. For new designs or ongoing production, the active SN74F02N is the recommended choice.

Q: Do these parts have different compliance certifications?

A: The SN74F02N is ROHS3 compliant, meeting current environmental standards. Both parts are REACH Unaffected. For applications requiring RoHS compliance, the SN74F02N is the appropriate selection.

Q: Are the electrical characteristics identical?

A: Yes. Both parts share identical voltage supply range (4.5V ~ 5.5V), output current ratings (1mA/20mA), input logic levels (0.8V low, 2V high), and propagation delay (5.5ns @ 5V, 50pF).
