Key Parameters

Substitute Part Grouping Explanation

The 74221-101LF qualifies as a parametric equivalent to the 74221-A01 based on strict alignment of electrical and mechanical specifications. Both parts share identical connector architecture, position count, pitch, row configuration, mounting methodology, contact material, finish thickness, and board height. The substitution relationship is determined solely by these matching parameters. The primary distinction between the two parts is packaging format: the 74221-A01 is supplied in Tape & Reel (TR) configuration, while the 74221-101LF is supplied in Cut Tape (CT) configuration. Both parts maintain the same base product number (74221) and series designation, confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the 74221-A01 and 74221-101LF are active products with full RoHS compliance and MSL 1 rating. Selection between these parts should be based on packaging requirements and supply chain constraints. The Tape & Reel (TR) packaging of the 74221-A01 is suitable for high-volume automated assembly operations. The Cut Tape (CT) packaging of the 74221-101LF accommodates lower-volume applications or situations where reel-based handling is not feasible. Both parts maintain identical electrical performance and mechanical compatibility with mating components. Inventory availability may also influence selection, as the 74221-101LF currently shows higher stock levels (1598 pcs) compared to the 74221-A01 (1043 pcs).

Frequently Asked Questions (FAQ)

Q: Are the 74221-A01 and 74221-101LF electrically identical? A: Yes. Both parts feature 400 positions, 0.050" pitch, 10-row configuration, gold contact finish at 30.0µin thickness, and identical board height specifications. Electrical performance is equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual handling or lower-volume assembly processes.

Q: Can I substitute the 74221-101LF for the 74221-A01 in my design? A: Yes, provided your assembly process can accommodate Cut Tape packaging. All electrical and mechanical specifications are identical, ensuring functional compatibility.

Q: Are both parts RoHS compliant? A: Yes. Both the 74221-A01 and 74221-101LF are RoHS compliant with MSL 1 rating.

Q: What does MSL 1 mean for moisture sensitivity? A: MSL 1 indicates unlimited moisture sensitivity level, meaning the component has no moisture sensitivity restrictions and does not require special storage or handling conditions.
