Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC4050D,652 is determined by strict equivalence across the following critical parameters:

• Base product number (74HC4050) ensures identical logic function and pinout
• Logic type (Buffer, Non-Inverting) and element configuration (6 elements, 1 bit per element)
• Output type (Push-Pull) and current specifications (5.2mA, 5.2mA)
• Supply voltage range (2V ~ 6V)
• Package type and physical dimensions
• RoHS3 compliance and moisture sensitivity level (MSL 1)

Substitute parts are categorized into two groups:

Upgrade Substitutes (CD74HC4050M, CD74HC4050M96, CD74HC4050MT): Texas Instruments manufactured variants with identical electrical specifications and package dimensions. These parts maintain full functional compatibility while offering improved product status or extended temperature operating range (-55°C ~ 125°C).

Similar Substitute (CD74HC4050NSR): Texas Instruments variant with identical electrical specifications but different package width (0.209", 5.30mm versus 0.154", 3.90mm), classified as similar rather than direct upgrade due to physical dimension variance.

Parameter Comparison

Engineering Selection Recommendations

For applications currently utilizing the 74HC4050D,652, the following selection criteria apply based on product status and compliance:

Primary Recommendation: CD74HC4050M96 (Texas Instruments) is the preferred substitute. This part maintains active product status, ensuring long-term availability and supply chain stability. It provides identical electrical specifications and package dimensions to the original part, with extended operating temperature range (-55°C ~ 125°C). Packaging is supplied in Cut Tape and Digi-Reel format with 15,812 units currently in stock.

Secondary Recommendations: CD74HC4050M and CD74HC4050MT are functionally equivalent alternatives with identical package dimensions and electrical specifications. Both are classified as Last Time Buy status, indicating limited future availability. CD74HC4050M is supplied in Tube packaging, while CD74HC4050MT is supplied in Tape & Reel format.

Package Variant: CD74HC4050NSR is functionally equivalent but features a different package width (0.209", 5.30mm versus 0.154", 3.90mm). This variant is suitable only for applications where PCB layout accommodates the larger package footprint. Active product status ensures continued availability.

All substitute parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, consistent with the original part specifications.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4050M96 be used as a direct replacement for 74HC4050D,652?

A: Yes. CD74HC4050M96 is a direct functional replacement. Both parts share identical base product number (74HC4050), logic configuration (6-element non-inverting buffer), output specifications (5.2mA push-pull), supply voltage range (2V ~ 6V), and package dimensions (16-SOIC, 0.154", 3.90mm width). The substitute offers extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 125°C) and active product status.

Q: What is the difference between CD74HC4050M, CD74HC4050M96, and CD74HC4050MT?

A: These three parts are electrically and functionally identical. The differences are in packaging format and product status. CD74HC4050M is supplied in Tube packaging (Last Time Buy status). CD74HC4050M96 is supplied in Cut Tape and Digi-Reel format (Active status). CD74HC4050MT is supplied in Tape & Reel format (Last Time Buy status). For new designs, CD74HC4050M96 is recommended due to active product status.

Q: Can CD74HC4050NSR be used instead of CD74HC4050M96?

A: CD74HC4050NSR is functionally equivalent but has a different package width (0.209", 5.30mm versus 0.154", 3.90mm). Substitution is possible only if PCB layout and component placement accommodate the larger package footprint. Electrical specifications and pinout are identical.

Q: Why is the 74HC4050D,652 classified as obsolete?

A: The original Nexperia part is obsolete, meaning it is no longer manufactured. Texas Instruments continues to manufacture functionally equivalent variants (CD74HC4050 series) that provide identical logic function and electrical performance. Substitution to an active product ensures design continuity and supply chain reliability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (CD74HC4050M, CD74HC4050M96, CD74HC4050MT, and CD74HC4050NSR) are ROHS3 compliant with MSL 1 moisture sensitivity rating, matching the original 74HC4050D,652 specifications.

Q: What is the operating temperature difference between the original part and substitutes?

A: The 74HC4050D,652 operates from -40°C to 125°C. All Texas Instruments substitutes (CD74HC4050M, CD74HC4050M96, CD74HC4050MT, CD74HC4050NSR) operate from -55°C to 125°C, providing an extended lower temperature range. This extended range does not affect compatibility for applications within the original temperature specification.
