Is there a difference between SOIC and SOP?

I'm looking at two integrated circuit packages: SOIC and SOP. They seem (almost) identical (pitch, overall size, etc...) SOP SOIC Is there any important differences between these two packages that I am overlooking?

DIP to SOIC-8 Adapter

I'm just getting round to a project that calls for a SOIC8 IC to be surfaced mounted on the PCB. The part it calls for is nowhere to be found (the backorder is several months at least!). I can, however, source a DIP8 version of the part. So, to…

SOIC -16 IC Orientation

I've just soldered a SOIC-16 am26c32 on to a breakout board. The datasheet shows the orientation of the chip by means of a semi circle at one end (http://www.ti.com/lit/ds/symlink/am26c32.pdf). However, on the actual device, there is no such semi…

Do SOIC op-amps packages behave differently from DIP?

I have acquired some mcp-6002 op-amps in a SOIC package instead of the DIP I normally use. I have solder these to a SOIC to DIP "converter" so to fit on the breadboard. If I connect them as I do with the DIP (as simple buffers for testing) they…

SOIC-8 package size error

I designed a PCB using both NE5532 and OP177 opamps. In principle both opamps are in SOIC-8 packages. However when I received the opamps, I found the NE5532 are much larger than the footprint they were designed to have on the PCB (using the KiCad…

Have SO(P)X components 2.54mm, 1.27mm or smaller pin spacings?

I'm a bit confused about the pin spacings of SO8/SOP8. Example: in Detail 2.54 SOP8, pin spacing is 2.54mm. However, according to Small_Outline_Integrated_Circuit, fragment: Small-outline package (SOP) After SOIC came a family of smaller form …

Difference between ESOP-8 and SOP-8?

I am ordering some parts for the first PCB projects I've designed in EasyEDA. One of the PMICs I am utilizing is the TP4056 which is listed as being in a "SOP-8_EP_150mil" package. Doing a broader search on LCSC I came across this IC which listed…

What would an acceptable replacement be for a discontinued Motorola HCT174A?

I am trying to replace a Hex D Flip-Flop on an Amiga A4000 motherboard. The original chip has the label HCT174A XAA346 I believe the datasheet describing this is the MC74HCT174A (though I can't find a reference to the XAA346), however, a BOM for…

How to identify Winbond W25Q64.V spi-flash chip replacement

I am trying to flash coreboot on to a Thinkpad T440p. It has two BIOS chips - "upper" 4MB and "bottom" 8MB. I use a Raspberry Pi 2 B+ and the skulls project to program in-situ (with a Pomona SOIC-8 clip). I also needed to test what is working and…

Help identifying an unknown SOIC-8 memory chip

I'm trying to dump the memory from a device for debugging. Based on what I know of the microcontroller (an ANYKA AK3918EN080) and the debug info returned from my failed attempts to dump the memory I presume it is some kind of SPI memory chip (but I…

How to connect wires from Orange Pi to DIP8 board without a numbered layout?

I read the documentation, it doesn't tell how to do it. I have an EEPROM chip containing the BIOS on my laptop's motherboard - an MX25L06E if you need the name. I have an Orange Pi Lite board, and I have a SOIC 8-pin clip like the one in this video.…
