Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74HCT241D,652 are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 6mA, 6mA
• Voltage - Supply: 4.5V ~ 5.5V
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional equivalence within the 74HCT logic family. Variations in operating temperature range, product status, and compliance certifications are noted but do not affect core substitutability.

Parameter Comparison

Engineering Selection Recommendations

MC74HCT241ADWR2G (onsemi) is the primary direct substitute. This part maintains all critical electrical and mechanical parameters while offering active product status and ROHS3 compliance. The extended operating temperature range (-55°C to 125°C) provides additional thermal margin compared to the original part. Packaging is supplied as Tape & Reel (TR), suitable for automated assembly processes.

CD74HCT241M96 (Texas Instruments) serves as an alternative substitute with active product status and ROHS3 compliance. This part also extends the operating temperature range to -55°C to 125°C. Packaging is supplied as Cut Tape (CT) & Digi-Reel®, accommodating both manual and automated assembly workflows.

CD74HCT241M (Harris Corporation) is functionally equivalent but carries obsolete product status and RoHS non-compliance. This part should be considered only when active alternatives are unavailable and legacy system requirements permit non-compliant components. The extended operating temperature range (-55°C to 125°C) is maintained.

For new designs and production continuity, MC74HCT241ADWR2G or CD74HCT241M96 are the recommended selections based on active product status and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can MC74HCT241ADWR2G directly replace 74HCT241D,652 in existing designs?

A: Yes. Both parts share identical logic type, element count, bit configuration, output type, current ratings, and supply voltage specifications. The 20-SOIC package dimensions are equivalent, enabling direct PCB footprint compatibility. The extended operating temperature range of MC74HCT241ADWR2G (-55°C to 125°C versus -40°C to 125°C) provides additional thermal margin without affecting substitutability.

Q: What is the difference between the packaging options offered by substitute parts?

A: MC74HCT241ADWR2G is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly. CD74HCT241M96 is supplied in Cut Tape (CT) & Digi-Reel® format, accommodating both manual and automated processes. Both packaging formats contain identical die and electrical performance; the difference is in handling and dispensing methodology.

Q: Why is CD74HCT241M listed as a substitute if it is RoHS non-compliant?

A: CD74HCT241M maintains all critical electrical and mechanical specifications required for functional substitution. However, its RoHS non-compliance status restricts its use to applications where legacy component requirements or specific regulatory exemptions apply. For new designs and production environments subject to RoHS regulations, MC74HCT241ADWR2G or CD74HCT241M96 are the appropriate selections.

Q: Are there any differences in 3-state output behavior between the main part and substitutes?

A: No. All parts in this comparison maintain identical 3-state output specifications with 6mA output current capability for both high and low states. Logic timing, output impedance characteristics, and state control mechanisms are functionally equivalent across all listed parts within the 74HCT logic family.

Q: Can substitutes be mixed in the same production batch?

A: Yes. All substitute parts meet identical electrical specifications and package dimensions. However, component traceability and supply chain documentation should reflect the specific manufacturer part number used in each assembly to maintain accurate bill-of-materials records and support future service or rework operations.
