Substitute Part Grouping Explanation

Substitution of the CD74AC623M96 is determined by strict equivalence across the following critical parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 1.5V ~ 5.5V
• Operating Temperature: -55°C ~ 125°C (TA)
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Substitute parts must maintain identical electrical characteristics and physical packaging to ensure direct functional replacement without circuit redesign. Packaging format (Tape & Reel or Tube) does not affect electrical compatibility but may influence procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both CD74AC245M96 and CD74AC623M are valid substitutes for the obsolete CD74AC623M96, as they maintain complete electrical and mechanical equivalence across all critical parameters. The primary distinction between these alternatives is product status and packaging format.

CD74AC245M96 is recommended for new designs and high-volume production due to its active product status, ensuring long-term availability and supply chain stability. This part is supplied in Tape & Reel format, which is standard for automated assembly processes.

CD74AC623M is suitable for maintenance, repair, and low-volume applications. Although active, this variant is packaged in Tube format, which may require manual handling during assembly. Both parts carry identical ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CD74AC245M96 and CD74AC623M be used interchangeably with CD74AC623M96?

A: Yes. Both substitute parts maintain identical electrical characteristics, output drive capability (24mA), supply voltage range (1.5V ~ 5.5V), operating temperature range (-55°C ~ 125°C), and 20-SOIC package dimensions. Direct substitution requires no circuit modifications.

Q: What is the difference between CD74AC245M96 and CD74AC623M?

A: The electrical and functional specifications are identical. The differences are: (1) CD74AC245M96 has active product status versus CD74AC623M which is also active; (2) CD74AC245M96 is supplied in Tape & Reel packaging suitable for automated assembly, while CD74AC623M is supplied in Tube packaging. Selection depends on production volume and assembly process requirements.

Q: Why is the original CD74AC623M96 obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and product lifecycle decisions. Active alternatives with identical specifications are available to ensure design continuity.

Q: Are there any compliance or certification differences between the substitute parts?

A: No. All three parts (CD74AC623M96, CD74AC245M96, and CD74AC623M) carry identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Which substitute should be selected for new production?

A: CD74AC245M96 is the recommended choice for new production due to active product status and Tape & Reel packaging format, which aligns with modern automated assembly workflows and ensures sustained supply availability.
