Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC147MT is determined by strict equivalence across the following parameters:

• Base product number (74HC147 series)
• Circuit configuration (1 x 10:4 priority encoder)
• Package type (16-SOIC surface mount)
• Electrical specifications (voltage supply, output current, operating temperature)
• Compliance certifications (RoHS3, REACH status)
• Moisture sensitivity classification

The CD74HC147M96 qualifies as a parametric equivalent substitute based on identical values across all these criteria. The primary distinction is packaging format (Cut Tape vs. Tape & Reel) and product status (discontinued vs. active).

Parameter Comparison

Engineering Selection Recommendations

The CD74HC147M96 is a direct parametric equivalent to the CD74HC147MT. Both components share identical electrical characteristics, package specifications, and compliance certifications. Selection between these parts should be based on:

• Product availability: CD74HC147M96 is active with 15,380 pcs in stock, compared to 1,297 pcs for the discontinued CD74HC147MT
• Packaging requirements: CD74HC147M96 is supplied in Tape & Reel format, while CD74HC147MT is available in Cut Tape format
• Supply chain continuity: For new designs or long-term production, CD74HC147M96 is the appropriate selection due to active product status

Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can CD74HC147M96 be used as a direct replacement for CD74HC147MT?

A: Yes. Both parts are identical in electrical performance, circuit configuration, package type, and compliance certifications. The only differences are product status and packaging format (Cut Tape vs. Tape & Reel).

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual component strips cut to specified lengths, suitable for smaller quantities and manual assembly. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for automated pick-and-place assembly and higher volume production.

Q: Are there any electrical differences between CD74HC147MT and CD74HC147M96?

A: No. Both parts have identical voltage supply range (2V ~ 6V), output current specifications (5.2mA high/low), and operating temperature range (-55°C ~ 125°C).

Q: Why is CD74HC147MT discontinued?

A: The CD74HC147MT is discontinued at DiGi Electronics. The active equivalent CD74HC147M96 provides the same functionality and specifications with improved supply availability.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both components use the 16-SOIC surface mount package with identical pinout and electrical characteristics, allowing direct substitution in existing PCB layouts without design modifications.

Q: What compliance certifications apply to both parts?

A: Both CD74HC147MT and CD74HC147M96 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronics manufacturing and distribution.
