Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT241SCX is determined by strict parametric matching across the following criteria:

Logic Type: Buffer, Non-Inverting
Number of Elements: 2
Number of Bits per Element: 4
Output Type: 3-State
Current - Output High, Low: 24mA, 24mA
Voltage - Supply: 4.5V ~ 5.5V
Operating Temperature: -40°C ~ 85°C (TA)
Package / Case: 20-SOIC (0.295", 7.50mm Width)
Mounting Type: Surface Mount

Parts are classified as parametric equivalents when all electrical and mechanical parameters match exactly. Parts are classified as similar when they share the same base functionality and package but may differ in product status, packaging format, or manufacturer.

Frequently Asked Questions (FAQ)

Q: Can I use SN74ACT241NSR as a direct replacement for 74ACT241SCX? A: SN74ACT241NSR is electrically equivalent but uses a 20-SO package (0.209" width) versus the 20-SOIC package (0.295" width) of the 74ACT241SCX. Physical board layout compatibility must be verified before substitution.

Q: What is the difference between 74ACT244SCX and 74ACT241SCX? A: Both parts share identical electrical parameters and package specifications. The primary difference is the base product number designation (74ACT244 vs. 74ACT241). Functional compatibility is maintained across all specified parameters.

Q: Are there RoHS compliance differences among the substitutes? A: Most active substitutes are ROHS3 compliant. CD74ACT241M96 is RoHS non-compliant and obsolete. Verify RoHS requirements for your application before selection.

Q: Which substitute has the highest inventory availability? A: MC74ACT244DWR2G (onsemi) has the highest inventory with 35,100 units in stock and active product status.

Q: Can I use parts with different packaging formats interchangeably? A: Packaging format differences (Tube, Tape & Reel, Cut Tape, Bulk) affect handling, storage, and assembly processes but do not affect electrical compatibility. Verify your assembly process requirements before substitution.

Q: Is NLV74ACT244DWR2G suitable for automotive applications? A: Yes, NLV74ACT244DWR2G carries AEC-Q100 qualification, making it suitable for automotive-grade applications. However, it is classified as obsolete.

Q: What moisture sensitivity level should I consider? A: The original 74ACT241SCX has MSL 1 (Unlimited). Most active substitutes have MSL 3 (168 Hours). Verify storage and handling requirements for your manufacturing environment.
