Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC4049N,652 is determined by the following critical parameters:

• Logic Type: Buffer, Inverting (6 elements, 1 bit per element)
• Output Configuration: Push-Pull
• Supply Voltage Range: 2V ~ 6V
• Output Current Capability: 5.2mA (high and low)
• Package Type: 16-DIP (0.300", 7.62mm)
• Series Compatibility: 74HC logic family
• Mounting Method: Through Hole

The CD74HC4049E qualifies as a direct functional substitute based on matching logic type, element count, output configuration, supply voltage range, package form factor, and through-hole mounting compatibility. Both parts operate within identical electrical parameters and physical constraints required for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4049E provides functional equivalence to the 74HC4049N,652 for applications requiring 6-element inverting buffer functionality in 16-DIP through-hole packages. Both parts share identical logic specifications, electrical operating parameters, and physical form factors.

Selection between these parts should account for regulatory compliance requirements. The 74HC4049N,652 maintains ROHS3 compliance, while the CD74HC4049E is RoHS non-compliant. For applications subject to RoHS directives or equivalent environmental regulations, the NXP part remains the preferred choice. For legacy systems or applications without RoHS requirements, the Harris part provides functional compatibility.

Both parts are classified as obsolete. Component availability should be verified through authorized distributors prior to procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4049E directly replace the 74HC4049N,652 on a PCB?

A: Yes. Both parts share identical 16-DIP package dimensions (0.300", 7.62mm), pin configurations, and electrical operating parameters. Direct board-level substitution is mechanically and electrically feasible.

Q: Are there differences in output current capability between these parts?

A: The parameter set provided specifies 5.2mA output current for the 74HC4049N,652. The CD74HC4049E maintains compatibility within the 74HC logic family specifications. Detailed output current specifications for the Harris part should be verified against the device datasheet.

Q: What is the primary difference between these substitute parts?

A: The primary distinction is RoHS compliance status. The 74HC4049N,652 is ROHS3 compliant, while the CD74HC4049E is RoHS non-compliant. Both parts are obsolete and provide identical functional performance.

Q: Should I consider supply voltage differences when substituting?

A: No. Both parts operate across the identical 2V to 6V supply voltage range and maintain the same operating temperature specification of -40°C to 125°C.

Q: Are there packaging or inventory considerations for selection?

A: The 74HC4049N,652 is available in standard packaging with 867 pieces in stock. The CD74HC4049E is supplied in tube packaging with 6829 pieces available. Packaging format and inventory levels may influence procurement decisions based on project requirements.
