74HC4050N,652 Equivalent & Substitute Parts

Part Overview

The 74HC4050N,652 is a non-inverting buffer logic integrated circuit manufactured by NXP USA Inc. in a 16-DIP through-hole package. This device functions as a 6-element buffer with push-pull output capability, designed for logic signal conditioning and distribution applications. The part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain functional equivalence across electrical specifications and mechanical compatibility within the 74HC4050 base product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the 74HC4050 family is determined by the following critical parameters:

• Logic Function: All substitutes must maintain non-inverting buffer operation with 6 elements, 1 bit per element
• Output Characteristics: Push-pull output type with specified current ratings
• Supply Voltage Range: 2V ~ 6V compatibility required
• Package Compatibility: Mechanical and electrical pin compatibility within DIP or surface-mount variants
• Electrical Performance: Output current ratings and operating temperature ranges must meet or exceed application requirements

Substitutes are grouped by mounting type: through-hole DIP packages maintain direct pin compatibility, while surface-mount variants (SOIC) require PCB redesign but offer equivalent electrical function.

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (Through-Hole DIP):

TC74HC4050AP(F) from Toshiba Semiconductor and Storage is the preferred active substitute. This part maintains 16-DIP package compatibility with the original 74HC4050N,652, offers higher output current capability (7.8mA vs. 5.2mA), and carries active product status with RoHS compliance. Operating temperature range is -40°C ~ 85°C, which covers standard industrial applications. This substitute is suitable for designs requiring through-hole mounting without PCB redesign.

For Surface-Mount Migration:

74HC4050D,653 from Nexperia USA Inc. provides an active, ROHS3-compliant alternative in 16-SOIC surface-mount packaging. This part maintains identical electrical specifications to the original (5.2mA output current, -40°C ~ 125°C operating range) and is recommended for new PCB designs or redesigns targeting surface-mount assembly. Higher inventory availability (10,053 pcs) supports production continuity.

For Compatibility with Extended Temperature Range:

CD74HC4050E from Harris Corporation extends the operating temperature range to -55°C ~ 125°C, suitable for applications requiring enhanced low-temperature performance. However, this part carries obsolete status and RoHS non-compliance, limiting its use to legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can TC74HC4050AP(F) directly replace 74HC4050N,652 without circuit modification?

A: Yes. Both parts are 16-DIP through-hole packages with identical pin configurations. The higher output current rating (7.8mA vs. 5.2mA) provides improved drive capability without requiring circuit changes. Operating temperature range (-40°C ~ 85°C) covers standard industrial specifications.

Q: What is the primary difference between through-hole and surface-mount substitutes?

A: Through-hole substitutes (TC74HC4050AP(F), CD74HC4050E) maintain direct PCB compatibility with the original 74HC4050N,652 and require no layout changes. Surface-mount substitute (74HC4050D,653) requires PCB redesign but offers advantages in automated assembly and board density. Electrical function remains identical across all variants.

Q: Why is 74HC4050D,653 recommended for new designs despite different packaging?

A: The 74HC4050D,653 carries active product status, ensuring long-term availability and supply chain stability. It maintains full electrical equivalence (5.2mA output current, 2V ~ 6V supply, -40°C ~ 125°C operation) while offering ROHS3 compliance and higher inventory levels. Surface-mount packaging is standard in modern PCB design practices.

Q: Are there output current differences between substitutes?

A: Yes. TC74HC4050AP(F) provides 7.8mA output current compared to 5.2mA in the original and other substitutes. This higher current capability is beneficial for driving heavier loads but does not affect compatibility with standard logic-level inputs. Applications with marginal current budgets should account for increased power dissipation.

Q: Which substitute is suitable for extended temperature applications below -40°C?

A: CD74HC4050E operates from -55°C ~ 125°C, extending the low-temperature range by 15°C. However, this part is obsolete and RoHS non-compliant, limiting its use to legacy system maintenance. For new designs requiring extended low-temperature performance, consult alternative logic families or contact the manufacturer for specialized variants.

Q: Is RoHS compliance a factor in substitute selection?

A: RoHS compliance status depends on application requirements and regional regulations. TC74HC4050AP(F) and 74HC4050D,653 are RoHS-compliant, meeting EU and similar regulatory frameworks. CD74HC4050E is RoHS non-compliant and should be avoided in regulated applications. The original 74HC4050N,652 is ROHS3 compliant.
