Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM74HC4050N are qualified based on the following critical parameters:

• Logic type and function: Buffer, Non-Inverting
• Element count: 6 elements
• Bits per element: 1 bit
• Output configuration: Push-Pull
• Supply voltage range: 2V ~ 6V
• Package type: 16-DIP (0.300", 7.62mm)
• Mounting method: Through Hole

Parts are grouped into three categories based on their alignment with these parameters:

Parametric Equivalent (MM74HC4049N): Matches all critical functional and package parameters with identical supply voltage range and similar output current specifications.

Direct Manufacturer Equivalent (CD74HC4050E): Maintains identical base product number (74HC4050) with matching logic configuration, package, and electrical characteristics. Extended operating temperature range provided.

Similar Substitute (TC74HC4050AP(F)): Matches all functional and package parameters with active product status. Output current specification differs within acceptable tolerance for 74HC logic family applications.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4050E provides direct equivalence with identical output current specifications (5.2mA, 5.2mA) and extended operating temperature range (-55°C ~ 125°C). This part is suitable for applications requiring wider temperature performance. RoHS non-compliance status must be evaluated against procurement requirements.

TC74HC4050AP(F) offers the advantage of active product status, ensuring continued availability and manufacturing support. Output current is specified at 7.8mA for both high and low states, representing a 50% increase over the original specification. This part is RoHS compliant and carries MSL Level 1 rating. Selection is appropriate for new designs or applications where higher output drive capability is acceptable.

MM74HC4049N maintains parametric equivalence with matching supply voltage range. Complete electrical specifications for output current and operating temperature are not provided in available documentation.

Frequently Asked Questions (FAQ)

Q: Can TC74HC4050AP(F) be used as a direct replacement for MM74HC4050N?

A: Yes. Both parts share identical logic configuration, element count, package type, and supply voltage range. The TC74HC4050AP(F) specifies higher output current (7.8mA versus 5.2mA), which is compatible with 74HC logic family applications. Active product status makes this the preferred choice for new procurement.

Q: What is the difference between MM74HC4049N and CD74HC4050E?

A: MM74HC4049N is a parametric equivalent with matching supply voltage specifications. CD74HC4050E shares the identical base product number (74HC4050) and provides extended operating temperature range (-55°C ~ 125°C). CD74HC4050E output current matches the original specification at 5.2mA.

Q: Are all substitute parts available in the same 16-DIP package?

A: Yes. All listed substitute parts use the 16-DIP (0.300", 7.62mm) package with through-hole mounting, ensuring mechanical and electrical compatibility in existing PCB designs.

Q: Does RoHS compliance affect part selection?

A: RoHS compliance status depends on procurement and regulatory requirements. TC74HC4050AP(F) is RoHS compliant. MM74HC4049N is ROHS3 compliant. CD74HC4050E is RoHS non-compliant. Verify compliance requirements before final selection.

Q: Which substitute part has the longest operating temperature range?

A: CD74HC4050E specifies -55°C ~ 125°C (TA), providing the widest temperature range among available substitutes. This part is suitable for applications requiring extended temperature performance.
