Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC4050DB,112 is determined by strict adherence to the following electrical and mechanical parameters:

• Base Product Number: All substitutes must share the 74HC4050 base designation, ensuring identical logic function and pin configuration
• Logic Type & Elements: Non-inverting buffer with 6 elements and 1 bit per element configuration must be maintained
• Output Characteristics: Push-pull output type and 5.2mA output current specifications must match
• Supply Voltage: 2V to 6V operating range is required for compatibility
• Mounting Type: Surface mount technology is mandatory
• Package Compatibility: Substitutes may use either 16-SSOP or 16-TSSOP packaging, as both are surface-mount variants with identical pin assignments
• Compliance: ROHS3 compliance and MSL Level 1 rating must be maintained

Substitutes are grouped by packaging type and product status. Operating temperature range may vary between -40°C and -55°C minimum specifications; both are acceptable for applications within the -40°C to 125°C envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 74HC4050PW,118 (Nexperia USA Inc., Active Status)

This substitute maintains identical electrical specifications and operating temperature range as the main part. Active product status ensures long-term availability and supply chain stability. The 16-TSSOP package is a direct functional equivalent with identical pin assignments, though with reduced package width (4.40mm vs 5.30mm). This part is suitable for new designs and production continuity.

Secondary Recommendation: CD74HC4050PWR (Texas Instruments, Active Status)

This Texas Instruments equivalent provides active product status with extended operating temperature range (-55°C to 125°C), offering enhanced performance margin for temperature-sensitive applications. The 16-TSSOP package matches the 74HC4050PW,118 specification. Cut Tape and Digi-Reel packaging supports both prototype and production volumes.

Alternative for Existing Inventory: CD74HC4050PWT (Texas Instruments, Last Time Buy)

This part maintains full electrical compatibility but carries Last Time Buy status, indicating limited future availability. Selection is appropriate only when existing inventory must be consumed or when design validation has been completed with this specific part number.

Not Recommended for New Designs: CD74HC4050PW (Texas Instruments, Obsolete Status)

Although electrically compatible, obsolete product status limits supply availability and future support. This part should be avoided for new production unless existing qualified inventory is available.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 74HC4050DB,112 with the 74HC4050PW,118 in my existing design?

A: Yes. Both parts share identical electrical specifications, output current ratings, supply voltage range, and operating temperature envelope. The primary difference is package geometry: 16-SSOP (5.30mm width) versus 16-TSSOP (4.40mm width). Pin assignments are identical, so PCB layout modifications are not required. Verify that your PCB footprint accommodates the 16-TSSOP package dimensions.

Q: What is the difference between 16-SSOP and 16-TSSOP packaging?

A: Both are surface-mount packages with identical pin counts and assignments. The 16-TSSOP package is narrower (4.40mm vs 5.30mm) and represents a more compact form factor. Electrical performance is identical. PCB footprint compatibility must be confirmed before substitution.

Q: Why are there multiple manufacturers for the same base part number?

A: The 74HC4050 is a standardized logic IC design. Both Nexperia USA Inc. and Texas Instruments manufacture versions that comply with the same functional and electrical specifications. All listed substitutes meet ROHS3 compliance and identical electrical parameters, ensuring interchangeability at the functional level.

Q: Does the extended operating temperature range of the Texas Instruments parts (-55°C to 125°C) provide any advantage?

A: The extended lower temperature limit (-55°C vs -40°C) provides additional margin for applications operating in extreme cold environments. For applications within the -40°C to 125°C range, both temperature specifications are functionally equivalent. Selection should be based on actual application requirements and product availability.

Q: Can I use CD74HC4050PW (Obsolete) in production?

A: Obsolete product status indicates that the manufacturer has discontinued production and support. While existing inventory may be available, long-term supply cannot be guaranteed. Use only when existing qualified inventory is confirmed and no alternative active parts are available.

Q: What does "Last Time Buy" status mean for the CD74HC4050PWT?

A: Last Time Buy indicates that the manufacturer has announced a final production run with a specified cutoff date. After this date, the part will no longer be available. This status is appropriate for consuming existing inventory but not for new long-term production commitments.
