Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74F1016DW is determined by strict equivalence across the following critical parameters:

• Base Product Number: Must be 74F1016 to ensure identical die and functional characteristics
• Logic Type: Must be Schottky Barrier Diode Bus-Termination Array
• Number of Bits: Must be 16
• Package / Case: Must be 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must be 0°C ~ 70°C
• RoHS and REACH Compliance: Must maintain ROHS3 Compliant and REACH Unaffected status

The primary distinction between the main part and its substitute lies in packaging format: the SN74F1016DW is supplied in Tube packaging, while the SN74F1016DWR is supplied in Tape & Reel (TR) format. Both parts share identical electrical and mechanical specifications, making them functionally interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

The SN74F1016DWR is a direct functional equivalent to the SN74F1016DW. Selection between these parts should be based on supply chain and procurement requirements rather than technical performance criteria.

The SN74F1016DW (Tube packaging) carries Last Time Buy status, indicating limited future availability. The SN74F1016DWR (Tape & Reel packaging) maintains Active product status with significantly higher inventory availability, making it the preferred choice for new designs and ongoing production requirements.

Both parts maintain identical ROHS3 compliance and REACH Unaffected certifications, ensuring regulatory alignment across substitution scenarios. The packaging format difference (Tube versus Tape & Reel) affects only the procurement and assembly process, not the electrical or mechanical performance of the component itself.

Frequently Asked Questions (FAQ)

Q: Are SN74F1016DW and SN74F1016DWR electrically identical?

A: Yes. Both parts share the same base product number (74F1016), logic type, bit count, package specification, and operating temperature range. They are functionally equivalent at the component level.

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

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-quantity applications. Tape & Reel packaging supplies components on continuous tape wound on reels, optimized for automated assembly processes and high-volume production. The component itself is identical; only the delivery format differs.

Q: Can I use SN74F1016DWR as a direct replacement for SN74F1016DW in existing designs?

A: Yes. The SN74F1016DWR is a direct substitute. No design modifications are required. The 20-SOIC package dimensions and pinout are identical, and all electrical specifications match.

Q: Why is the SN74F1016DW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The SN74F1016DWR (Tape & Reel format) remains in active production and is the recommended alternative for future procurement.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance and REACH Unaffected status. Regulatory requirements are satisfied by either part.

Q: What inventory considerations should I account for?

A: The SN74F1016DW has 713 pieces available in Tube format. The SN74F1016DWR has 3916 pieces available in Tape & Reel format. For designs requiring high-volume production or long-term supply assurance, the SN74F1016DWR is the more reliable choice due to its Active status and higher available inventory.
