Fixed 5-tap delay line for 5 V timing alignment
The DS1004C-303: It provides one independent delay path with five taps, the first tap at 5 ns. The supply range is 4.75 V to 5.25 V, and the operating temperature range is 0°C to 70°C — commercial grade only, so keep it inside conditioned equipment or office gear. Because the delay profile is nonprogrammable, there is no external resistor or capacitor to set; the timing is fixed at manufacture. This part is active in the current lifecycle stage, so no immediate EOL concern for new designs.
RoHS non-compliant — plan your BOM accordingly
The DS1004C-303 is marked RoHS non-compliant. That means it contains lead or other restricted substances above the RoHS threshold. For EU-regulated equipment, medical devices, or any BOM that requires RoHS compliance, this part will not pass. It is still an active, current-production part (lifecycle stage: current), so it is available through independent distribution for non-RoHS projects, legacy support, or military/aerospace builds where leaded solder is acceptable.
Sourcing and supply posture
This part is active and available through independent distribution. No last-time-buy or EOL notice is in effect. For volume production or legacy board support, the non-RoHS status is the main gate — confirm your compliance requirements before ordering.
