PIC16F628A DIP-18 Microcontrollers & PIC16 Model Options

PIC16F628A through-hole MCU selection

This collection brings together five loose-chip offers that include a selectable PIC16F628A option. They are multi-model listings for 18-pin DIP-style PIC16 microcontrollers, not five different development boards and not assortments containing every chip named in a product title. Three listings use a model choice under an option labelled “Color”; select PIC16F628A if that is the MCU needed. Other selectable model labels include PIC16F54, PIC16F88, PIC16F627A, PIC16F648A, PIC16F716, PIC16F818, PIC16F1826 and PIC16F1827, with PIC16F819 offered in one listing. These are separate order choices, not interchangeable aliases for PIC16F628A.

What the listings actually offer

• Model-selectable five-piece offers: three product titles specify 5 pcs and provide a choice of PIC16 model; select the PIC16F628A variant for five of that named device, subject to the specific offer's displayed quantity at checkout. “Color” is a seller's option label for the selected chip model, not a physical color or a mixed set. The product descriptions provide little electrical detail beyond DIP or DIP-18 wording, so do not infer an exact operating voltage, oscillator configuration or certification from their generic category fields.
• Model-selectable single-piece offer: another title starts with 1PCS and lists multiple PIC16 models, including a PIC16F628A variant. Its title includes both PIC16F627 and PIC16F627A wording while the available choice shown is PIC16F627A; order by the selected model, not by a passing model mention in the title.
• PIC16F628A quantity-selectable offer: one product is specifically titled PIC16F628A-I/P, DIP-18, and offers 1PCS, 2PCS or 5PCS as choices. Here “Color” represents pack quantity rather than MCU model. Confirm the selected quantity and the actual top marking; the generic description's claims about certification and delivery are seller text, not independent device documentation or a universal store promise.

Specify the complete part, not just the PIC16 prefix

The PIC16F628A is an 8-bit programmable MCU in the listed through-hole DIP-18 format; the bare IC has no development board, power supply, USB interface, firmware or programmer included by implication. Verify the exact manufacturer ordering suffix (including -I/P when specified), DIP pin-1 orientation, footprint and socket, supply-voltage range, temperature grade and pin functions against the manufacturer's device datasheet and the physical marking. A description that calls the chip a “voltage regulator” or “drive IC” is a generic marketplace category and does not change its MCU function. Do not infer manufacturer authenticity from “new original” in a title.

Before replacing an existing MCU, compare program memory, RAM, EEPROM if used, oscillator options, peripheral set, analog/comparator behavior, configuration bits, programming requirements and pin assignments for the exact two devices. PIC16F627A, PIC16F648A, PIC16F88 and newer PIC16F1826/1827 parts can have different memories and peripherals even when offered in an 18-pin through-hole form. A matching DIP-18 outline alone does not establish software or circuit compatibility. Compile for the chosen target, set the appropriate configuration bits, use a programmer that supports that exact device and confirm the target-circuit programming pins are accessible. Validate in-circuit programming voltage and pin loading from the official programming specification rather than guessing from a shared socket shape.

For prototypes, consider whether the chosen socket or board routes the oscillator, reset and programming functions you intend to use. For a production bill of materials, record the full manufacturer code, package, quantity per order and marking acceptance criteria; do not use a title containing ten PIC16 numbers as the BOM part number. If your design requires a particular temperature grade, traceability or independently verified provenance, seek documentation for the specific lot rather than relying on a general seller claim.

Frequently asked questions

Does a title listing ten PIC chips mean I receive all ten? No. The multi-model listings have a selected MCU-model variant. Pick PIC16F628A explicitly; the five-piece and one-piece titles indicate different offer quantities.

What does “Color: PIC16F628A” mean? In these products it is the storefront label attached to a model selection, not the color of the IC. On the dedicated PIC16F628A listing the same option label instead contains 1PCS, 2PCS or 5PCS, meaning pack quantity.

Can PIC16F628A replace PIC16F627A or PIC16F1827 without changes? Not on the basis of the package alone. Check firmware target, memory, peripherals, configuration, electrical limits and pin usage against both device datasheets.

Are these assembled learning boards? No. The five reviewed product descriptions and options describe loose DIP-style IC offers; no board or preloaded application is established.

Is PIC16F628A-I/P guaranteed for every PIC16F628A option? The dedicated listing names that full code, while the multi-model choices show PIC16F628A without consistently giving the entire orderable suffix. Confirm the exact marking and grade on the individual offer before placing a suffix-sensitive order.
