Product details

The 100131DC is a D flip-flop from the 100K ECL logic series, designed for high-speed clocked storage in emitter-coupled logic systems. A single flip-flop per package with complementary Q and Q-bar outputs.

No NRND or last-time-buy notice applies. The RoHS compliance status is marked non-compliant, which means the device uses tin-lead (SnPb) solder finish — verify your assembly line's exemption or waiver before ordering.

— loose units, not on tape, reel, or tray. For automated pick-and-place, you will need to load the parts into tube feeders or trays manually. The Bulk designation also means the parts may ship in anti-static bags or tubes; confirm the exact packaging format with the supplier at quote time.

Frequently asked questions

Is 100131DC RoHS compliant?

No, 100131DC is marked RoHS non-compliant, meaning it uses tin-lead (SnPb) solder finish. Verify your assembly process can accept SnPb before ordering.

What is the equivalent part for 100131DC?

Functional equivalents in the same logic class include SN74276N and SN74175N, though these are TTL-series parts — not drop-in replacements. For a 100K ECL pin-compatible alternative, JM38510/30105BCA is a JAN-qualified D flip-flop that may match the footprint; verify the pinout and supply voltage before substituting.

Is 100131DC compatible with 100K series logic?

Yes, 100131DC is a member of the 100K ECL series, so it is electrically compatible with other 100K-series logic on the same -4.5 V or -5.2 V supply rail.
