Substitute Part Grouping Explanation
Substitution of the CD74HC4049M96 is determined by strict equivalence across the following critical parameters:
- Base product number (74HC4049)
- Logic type and functional configuration (Buffer, Inverting)
- Number of elements (6) and bits per element (1)
- Output type (Push-Pull)
- Output current specifications (5.2mA, 5.2mA)
- Supply voltage range (2V ~ 6V)
- Package type (16-SOIC)
- Compliance certifications (ROHS3, REACH Unaffected)
Substitute parts must maintain identical electrical performance characteristics and physical package compatibility. Variations in product status or operating temperature range do not preclude substitution when all other parameters align.

Engineering Selection Recommendations
The CD74HC4049M96 and its substitutes are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and deployment.
CD74HC4049MT is a parametric equivalent manufactured by Texas Instruments with identical electrical specifications. This part carries Last Time Buy status, indicating limited future availability. Selection of this substitute should account for long-term supply planning.
74HC4049D,653 is the manufacturer-recommended substitute produced by Nexperia USA Inc. and maintains Active product status. This part exhibits a narrower operating temperature range (-40°C to 125°C) compared to the main part (-55°C to 125°C). Selection of this substitute is appropriate for applications operating within the -40°C to 125°C temperature window. All three parts share identical electrical performance, output current ratings, supply voltage specifications, and package dimensions.
Frequently Asked Questions (FAQ)
Q: Can CD74HC4049MT be used as a direct replacement for CD74HC4049M96?
A: Yes. Both parts are manufactured by Texas Instruments and share identical electrical specifications, output current ratings, supply voltage range, operating temperature range, and 16-SOIC package configuration. The primary distinction is product status; CD74HC4049MT is Last Time Buy, indicating reduced future availability.
Q: Is 74HC4049D,653 compatible with CD74HC4049M96 in all applications?
A: Electrical and package compatibility are confirmed. The 74HC4049D,653 operates across -40°C to 125°C, while the CD74HC4049M96 operates across -55°C to 125°C. Applications requiring operation below -40°C must use the CD74HC4049M96 or CD74HC4049MT.
Q: Are all substitute parts housed in the same package?
A: Yes. All three parts use the 16-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical and footprint compatibility on printed circuit boards.
Q: What compliance certifications apply to these parts?
A: All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
Q: How do output current specifications affect substitution?
A: All three parts deliver identical output current: 5.2mA for both high and low states. Output current capacity is equivalent across all substitutes.
