Substitute Part Grouping Explanation

Substitution of the SN74HC240N-P2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Logic type must be Buffer, Inverting
• Element count must equal 2
• Bits per element must equal 4
• Output configuration must be 3-State
• Output current specifications must match: 7.8mA (High), 7.8mA (Low)
• Supply voltage range must be 2V ~ 6V
• Operating temperature range must be -40°C ~ 85°C

Mechanical Equivalence Criteria:

• Package type must be 20-DIP (0.300", 7.62mm)
• Mounting type must be Through Hole
• Base product number must be 74HC240

Compliance Criteria:

• RoHS3 compliance required
• Active product status required

The SN74HC240N qualifies as a parametric equivalent substitute based on identical electrical specifications, mechanical dimensions, and compliance certifications. The primary distinction between the main part and substitute relates to packaging format (Tube versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both the SN74HC240N-P2 and SN74HC240N are active-status components manufactured by Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Inventory Availability: The SN74HC240N maintains higher inventory levels (2572 Pcs) compared to the SN74HC240N-P2 (1133 Pcs), making it suitable for applications requiring immediate procurement or larger volume requirements.

Packaging Format: The SN74HC240N is supplied in Tube packaging, while the SN74HC240N-P2 uses standard packaging. Tube packaging is appropriate for automated assembly processes and high-volume production environments.

Compliance Status: Both parts maintain ROHS3 compliance and active product status, ensuring long-term availability and regulatory adherence for industrial and commercial applications.

Functional Interchangeability: Complete electrical and mechanical equivalence permits direct substitution in circuit designs without modification to PCB layouts, schematic designs, or firmware implementations.
