SparkFun SOIC to DIP Adapter - 8-Pin
Your basic SOIC break out boards. What's the difference? The 8 Pin board is TINY. And you can't beat the price! These are custom PCB boards that interface standard JEDEC SOIC devices to standard .1" headers.
This board has a standard SOIC-8 footprint with a layout that fits all standard JEDEC SOIC-8 devices.
40 Pin break-away headers are perfect for use with these custom PCBs. Machine pin headers may be a better option for IC sockets.

very good
This is a good PCB, good quality and clean. This PCB would be smaller and works better for me if the SOIC footprint moves in between the DIP foot print. Thanks, Ron

cost too much, and no pins
They cost about 3 times what I expected to pay, and then I had to go out and buy pins so that I could insert the adapter into my prototyping board.
Perfect for for prototyping with little 8-pin soic
once attached to adapter, the soic device is now breadboard friendly.
Easy to solder
The pads for the SOIC are long so easy to solder even if the chip isn't perfectly straight.
I have to agree with the other comments, the pads on this could be MUCH longer. Even when I bent the chip's pins inwards, the pins sat right on the furthest extremities of the pads.
If Sparkfun is designing these, they -really- need to manually lengthen the pads, and then introduce it as a new part (If I know it's redesigned, I'll give it another chance, but right now I will try someone else's adapter instead).
make sure you check the SOIC-8 you are planning to solder to these before you buy them!..if the pads had been made a bit longer on the soic layout then they could have been used for more "SOIC-8" packages....threw the Sparkfun ones in the trash and bought some from a different vendor that have a better layout for less.
The second I touched the pads with soldering iron 3 pulled right off, I used temp controlled soldering Iron on only 280 degrees and I was very careful I would not recommend this board I ended up using wire wrap to complete connections because the darn pads for the smt pulled right off
"SOIC" here refers to the JEDEC SOIC package whose body is 3.8mm wide, unlike the EIAJ which looks similar but is actually 5.3mm wide. Some more details here (which I should have read before buying):

Good catch xxv. I just made the same mistake and then saw your comment. The product description is now changed.
Thanks!
I know of an excellent application for this board. Sparkfun you guys should look into making up a batch using this board and the DS2482-100 which is an I2C to One-Wire translation device.
Making these up, using those chips and this board requires an exacting talent, and steady hands, and good tools. I think I've got all of that, but I believe all of you have the tools to do the job and better.
Will this work for what TI is calling their "narrow SOIC" package? I need to experiment with some Low Voltage OP amps in this case LME49721, and i can't imagine doing so without the ease of whit boarding. The TI data sheet for this chip at http://www.ti.com/lit/ds/snas371b/snas371b.pdf but I don't see any reference to whether or not is "JEDEC SOIC".
There's no datasheet / eagle files listed on this page, but from measuring pixels I'd say you should be fine. The 'narrow' SOIC is actually the typical SOIC. There's also a wide body SOIC for which the pads on this might be a bit too short though I'd bet you could still solder one of those on, too.
Has anyone used this as a breakout for the Lassen IQ? The connector has a pitch of 0.5", but i'm not sure of the width.
Hi,
can this be used for TSL230RD
A little help appreciated
Thanks
Got two of these for quick BIOS swapping. Of note:
1. SIZE (See the earlier comments by xxv and Member63167). To re-cap: the pitch for the SOIC lands is the standard 1.27mm, but their complete lead-to-lead width (outside edge pin1 to outside edge pin8) is only 7.45mm. As luck would have it, my chips turned out to be the EIAJ "wide/extended" format, so I had to crush the pins inward with a pair of pliers to have them all connect. I understand that the small size is a feature of this board, but it could be made properly compatible with EIAJ chips with a width increase of 2mm or less. The Wikipedia link xxv posted got eaten by the site, the following one is working: SOIC specs @ Wikipedia
2. The pads did not seem to want to make a very good connection even though I pre-tinned them (using standard 63/37 solder)
3. Several of the pads did lift of the PCB during soldering, but none actually broke. Probably not helped by extended heating, due to #1, #2 and the use of a cheap uncontrolled 35W iron.
The dimensions in the text do not seem to match the images. The text says it is .78" long and the image shows over 1". Which is correct? Thank you.
Look at the image again, the image is cut off before it ever gets to 1". Those are centimeters you're seeing.
It's a little over 1 and 1/2 cm long and a little over 1 cm wide, or .78" long and .5" wide.
I purchased several of these to fan out a Numonyx M25P16 serial flash memory. I did not experience any problems as the previous user did. I would recommend these to someone considering them.
No eagle file available?
The holes for the header on the board I purchased from sparkfun are too small for some square post headers. Purchase their breakaway headers or machine pin headers for a proper fit, or use straight pins and cut off thier excess length.
