CD74HC4050M Equivalent & Substitute Parts

Part Overview

The CD74HC4050M is a non-inverting buffer logic integrated circuit manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This device functions as a 6-element buffer with push-pull output capability, operating across a 2V to 6V supply voltage range. The part is classified as Last Time Buy status, indicating it is no longer in active production. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and support long-term product availability for applications requiring this buffer functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4050M is determined by strict equivalence across the following critical parameters: logic type (non-inverting buffer), number of elements (6), bits per element (1), output type (push-pull), output current capability (5.2mA high and low), supply voltage range (2V ~ 6V), package type (16-SOIC), and mounting method (surface mount). All substitute parts listed maintain identical functional and electrical specifications within these parameters. Packaging format variations (tube, cut tape, tape & reel) do not affect electrical compatibility and represent alternative distribution methods for the same base product number 74HC4050.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4050M96 is the manufacturer-recommended primary substitute, produced by Texas Instruments under active product status. This part maintains identical electrical and thermal specifications to the original CD74HC4050M, with the primary difference being packaging format (cut tape and Digi-Reel distribution versus tube). This substitute is suitable for applications requiring continuity with the original design without thermal or performance trade-offs.

74HC4050D,653 and 74HC4050D-Q100J are alternative substitutes manufactured by Nexperia USA Inc., both in active production status. These parts maintain functional equivalence across all critical electrical parameters. The operating temperature range for Nexperia variants is -40°C to 125°C, which is narrower than the original -55°C to 125°C specification. Selection of Nexperia substitutes is appropriate for applications operating within the -40°C to 125°C range.

74HC4050D-Q100J carries automotive-grade qualification (AEC-Q100), making it suitable for automotive and high-reliability applications requiring formal qualification documentation.

All substitute parts comply with ROHS3 and maintain MSL 1 classification, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4050M96 be used as a direct replacement for CD74HC4050M?

A: Yes. CD74HC4050M96 is electrically and functionally identical to CD74HC4050M. Both are manufactured by Texas Instruments with identical logic specifications, output current ratings, supply voltage range, and operating temperature range. The difference is packaging format: CD74HC4050M is supplied in tube packaging, while CD74HC4050M96 is supplied in cut tape and Digi-Reel format. Pin configuration and PCB footprint are identical.

Q: What is the temperature difference between Texas Instruments and Nexperia variants?

A: Texas Instruments CD74HC4050M and CD74HC4050M96 operate from -55°C to 125°C. Nexperia variants (74HC4050D,653 and 74HC4050D-Q100J) operate from -40°C to 125°C. For applications requiring operation below -40°C, Texas Instruments parts are required. For applications within -40°C to 125°C, both manufacturers' parts are suitable.

Q: Is 74HC4050D-Q100J suitable for automotive applications?

A: Yes. 74HC4050D-Q100J carries AEC-Q100 automotive qualification. This part is appropriate for automotive and high-reliability applications requiring formal qualification documentation and compliance with automotive standards.

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

A: Yes. All listed substitute parts use the 16-SOIC (0.154", 3.90mm width) surface mount package. PCB footprint and pin configuration are identical across all parts, enabling direct board-level substitution.

Q: What is the difference between tube, cut tape, and tape & reel packaging?

A: These are distribution and handling formats that do not affect the electrical or functional characteristics of the component. Tube packaging is used for smaller quantities and manual handling. Cut tape and Digi-Reel are used for higher-volume automated assembly processes. The base product and specifications remain identical regardless of packaging format.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed parts, including the original CD74HC4050M and all substitutes, are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) classification.
