74F30PC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74F30PC is a NAND Gate IC featuring 1 channel with 8 inputs, housed in a 14-MDIP package. Manufactured by onsemi, this component operates within the 74F logic series and is classified as obsolete. Due to its obsolete status and limited availability from the original manufacturer, identifying active equivalent parts is essential for system redesign, maintenance, and procurement continuity. The SN74F30N from Texas Instruments provides a direct functional and electrical equivalent with active product status.

Substitute Part Grouping Explanation

Substitution of the 74F30PC with the SN74F30N is based on strict equivalence across all critical electrical and mechanical parameters:

Matching Parameters:

• Logic type, circuit count, and input configuration (NAND Gate, 1 channel, 8 inputs)
• Supply voltage range (4.5V ~ 5.5V)
• Input logic thresholds (0.8V low, 2V high)
• Output current specifications (1mA high, 20mA low)
• Propagation delay performance (5ns @ 5V, 50pF)
• Operating temperature range (0°C ~ 70°C)
• Physical package dimensions (14-DIP, 0.300" pitch, 7.62mm)
• Through-hole mounting compatibility

The SN74F30N maintains identical functional and electrical characteristics while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74F30N is the appropriate substitute for the 74F30PC based on the following factors:

Product Status: The 74F30PC is classified as obsolete, whereas the SN74F30N maintains active product status with established supply chains and manufacturing continuity.

Regulatory Compliance: Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring equivalent compliance posture in regulated applications.

Electrical Equivalence: All functional parameters—logic operation, voltage specifications, timing characteristics, and output drive capabilities—are identical between the two parts.

Physical Compatibility: Both components utilize the same 14-DIP package with 0.300" pitch spacing, enabling direct socket substitution without PCB redesign.

Availability: The SN74F30N offers significantly higher inventory availability (6323 units) compared to the obsolete 74F30PC, supporting both new production and field replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the SN74F30N be used as a direct replacement for the 74F30PC without circuit modifications?

A: Yes. The SN74F30N is electrically and mechanically equivalent to the 74F30PC. All electrical parameters, including supply voltage, logic thresholds, propagation delay, and output drive, are identical. The 14-DIP package dimensions are the same, allowing direct socket substitution.

Q: What is the difference between the 74F30PC and SN74F30N?

A: The primary differences are manufacturer (onsemi vs. Texas Instruments) and product status (obsolete vs. active). The SN74F30N offers active production status, improved availability, and RoHS3 compliance. All functional and electrical specifications remain identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 14-DIP package with 0.300" (7.62mm) pitch. Pinout and physical dimensions are identical, ensuring compatibility in existing PCB designs.

Q: Why is the 74F30PC listed as obsolete?

A: The 74F30PC has reached end-of-life status with onsemi. The SN74F30N from Texas Instruments provides continued availability of the same logic function with active manufacturing support.

Q: What compliance certifications apply to both parts?

A: Both the 74F30PC and SN74F30N are REACH Unaffected and classified under ECCN EAR99. The SN74F30N additionally carries RoHS3 compliance certification.

Q: Can the SN74F30N be used in high-temperature applications?

A: Both parts operate within the 0°C to 70°C temperature range. For applications requiring extended temperature operation, alternative qualified parts with higher temperature ratings must be evaluated.
