Replacement verdict
Compatible functional replacement candidate
The 74HC4051D and 74HC4051D,652 are functionally equivalent 8-channel analog multiplexers/demultiplexers from the same manufacturer, sharing identical electrical characteristics, package type, and pin configuration. The only distinction is the ordering format, where the ,652 suffix denotes a tape-and-reel packaging option. Both parts are suitable for direct substitution in the same application without design changes.

Frequently asked questions
Are the 74HC4051D and 74HC4051D,652 the same device?
Yes. Both part numbers refer to the same Nexperia 74HC4051D 8-channel analog multiplexer/demultiplexer in a SO16 (SOT109-1) package. The suffix ",652" is a Nexperia ordering code that specifies tape-and-reel packing; the base type 74HC4051D is the same die and package.
What is the difference between 74HC4051D and 74HC4051D,652?
The electrical and functional characteristics are identical. The difference is the packing/ordering format: 74HC4051D,652 designates the tape-and-reel option (reel diameter and quantity per reel per Nexperia packing data), while 74HC4051D may be ordered in other packing forms such as bulk or tube depending on the distributor listing.
Can 74HC4051D and 74HC4051D,652 be used interchangeably in a design?
Yes, from a functional and footprint standpoint they are interchangeable because they share the same die, SO16 package, and pinout. The only practical consideration is the packing format required by the assembly line; the reeled version (74HC4051D,652) is intended for automated pick-and-place, while other packing options may suit manual or low-volume assembly.
What are the key specifications of the 74HC4051D?
The 74HC4051D is an 8-channel analog multiplexer/demultiplexer with a wide supply voltage range of 2.0 V to 10.0 V, low ON resistance, and TTL-compatible control inputs. It features break-before-make switching, a common enable input, and three digital select inputs (S0, S1, S2) to address one of eight channels. It operates over the -40 °C to +125 °C temperature range and is supplied in a SO16 package.
Is the 74HC4051D,652 RoHS compliant?
Yes. Nexperia lists the 74HC4051D,652 as RoHS compliant and halogen-free according to the manufacturer's material declaration. The base 74HC4051D shares the same package and material composition, so it is also RoHS compliant when sourced from Nexperia.
What is the function of the 74HC4051D in a circuit?
The 74HC4051D is an 8-channel analog multiplexer/demultiplexer. It can route one of eight analog or digital signals to a single common output (multiplexing) or distribute one common signal to one of eight outputs (demultiplexing), controlled by three binary select inputs and an enable pin. It is commonly used for signal routing, data acquisition, and audio/video switching.
Does the 74HC4051D,652 have the same pinout as the 74HC4051D?
Yes. Both part numbers use the SO16 (SOT109-1) package with identical pin assignments: Y0–Y7 are the eight independent channels, Z is the common input/output, S0–S2 are the select inputs, E is the enable input, VCC is the positive supply, VEE is the negative supply (or ground for single-supply operation), and GND is ground.
Which part number should be used for automated assembly?
74HC4051D,652 is the tape-and-reel ordering code intended for automated pick-and-place assembly. The base 74HC4051D may be supplied in bulk or tube packing depending on the distributor, which is less suitable for high-speed automated placement.
