Product details

The SN74S03D is a TTL NAND gate from the S series, supplied in bulk packaging.

RoHS status — what it means for your line

This part is RoHS non-compliant. If your assembly line runs lead-free solder profiles, the SN74S03D will not pass a RoHS material declaration. It belongs on a legacy BOM where tin-lead solder is still accepted, or on a controlled exemption. Verify your end-product RoHS exemption before committing the line.

Lifecycle and sourcing

The SN74S03D is listed as Active in production. There is no NRND or last-time-buy notice. For volume requirements, the part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.

Package and rework note

The bulk package designation typically means the part ships in tubes or loose quantities, not tape-and-reel. The leads are tin-lead plated.

Frequently asked questions

What are the differences between SN74S03D and common alternatives like 74LS03?

The SN74S03D is from the S series (Schottky TTL), which typically offers higher speed than the LS (Low-Power Schottky) series. The 74LS03 is a lower-power, slower alternative. Both are quad 2-input NAND gates with open-collector outputs, but the S series has tighter propagation delay at the cost of higher power consumption.

Can SN74S03D be used as a direct replacement for SN74S03N?

The SN74S03D and SN74S03N share the same S-series TTL NAND gate function. The suffix indicates package type: D typically denotes a SOIC surface-mount package, while N denotes a plastic DIP. They are not pin-compatible for the same footprint — verify your board's package before substituting.
