Engineering Selection Recommendations

SN7417N (Texas Instruments) is the direct manufacturer equivalent, offering identical electrical specifications and package configuration. This part is actively manufactured and ROHS3 compliant, providing the most straightforward replacement path for the obsolete DM7417N.

SN7407N (Texas Instruments) is a parametric equivalent within the standard 7400 series. It maintains all critical electrical and mechanical parameters while offering active product status and ROHS3 compliance. This part provides an alternative source with higher current inventory availability.

SN74LS07N (Texas Instruments) is a parametric equivalent from the 74LS logic family, which operates at reduced power consumption compared to standard 7400 series devices. All electrical specifications for this application remain identical. This part is actively manufactured, ROHS3 compliant, and offers the highest inventory availability among the listed substitutes.

All three substitute parts are suitable for direct replacement in applications originally designed for the DM7417N, with selection based on procurement availability, cost considerations, and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74LS07N replace DM7417N in my circuit? A: Yes. The SN74LS07N meets all electrical and mechanical specifications required for DM7417N applications. The 74LS series operates at lower power consumption than standard 7400 series, but maintains identical voltage supply range, output current rating, and package configuration.

Q: What is the difference between SN7417N and SN7407N? A: Both parts are functionally equivalent for this application, meeting identical electrical specifications. SN7407N offers higher inventory availability. Selection between these parts should be based on procurement lead time and cost.

Q: Are all substitute parts in 14-DIP packaging? A: Yes. All listed substitute parts use 14-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical compatibility with PCB layouts designed for the DM7417N.

Q: Why is the DM7417N listed as obsolete? A: The DM7417N is no longer manufactured by onsemi. Active equivalents from Texas Instruments (SN7417N, SN7407N, SN74LS07N) provide continued design support and procurement options.

Q: Are the substitute parts RoHS compliant? A: Yes. SN7417N, SN7407N, and SN74LS07N are all ROHS3 compliant, whereas the original DM7417N is RoHS non-compliant.

Q: What is the maximum output current for these buffers? A: All parts in this comparison, including DM7417N and its substitutes, are rated for 40mA output low current.
