I like it. I don't mind registration. In fact, it apparently took my registration credential from some other site. Maybe eeTimes. When I clicked to register, it just logged me in. It's a good early effort. I like the fact that some of the key parameters are listed in the search results. It drives me nuts when sites like this give so little information that I have to go through every single returned data sheet to see if it's even close to what I'm looking for. My advice would be to add in more key parameters in the search return table. Think in terms of the need to scan through a few dozen or hundred listed parts to quickly narrow down the search to a small handful. The ability to filter a search is useful as well. Although, I'd add the capability to filter on a few additional parameters. I searched for a tantalum cap and the filter let me filter on manufacturer. It would be nice to be able to filter on voltage or a few other parameters. Showing inventory at various distributors when available is a nice touch too.

This is good effort. However, in this development, database software person is more involved and EE Design Engineer with hands-on experience less involved. If you involve EE design engineer from varius industry - like Military, RF, Medical, Precision analog, sensor, control, instrumentation, power etc. they can guide you their unique requirements when they look for different parts. This will be very valuable feedback. I am ready to volunteer for contribution.

I like it too, but as stated before by Duane benson, more parameters need to considered. In addition, I noted that the sorting of parameter values is alphanumeric instead of arithmetical value. It would be more intuitive if the searcher can done a linear search of values ranges, instead of having to poke around the different choices for each parameter. Good work so far, enjoyed the ability to do multiple vendor comparisons. But limited to 4 sources, it could be improved to a higher limit, why not ability to export as spreadsheet?

Great feedback, guys, thanks! This is exactly what's going to help make it better and better over the coming weeks and months. Just having a top-tier parametric search capability is a feat unto itself, especially for a such a massively broad range of products, so digging deeper and increasing the granularity of the parameters will be an on-going mission! Stay tuned! HM: If you'd seriously like to help, I'm at patrick.mannion@ubm.com. Thanks!

This all sounded very exciting. So I went over to datasheets.com to look at the parametric search in the op-amps section. What parameters did they have available? Vendor, Type, No. of Channels, Technology. That's it! What about the things that I *actually care about*? Like power supply voltage min/max, quiescent power-supply current, input offset voltage, input bias current, input offset current, input voltage noise density, input current noise density, max output current, CMRR, PSRR, input common-mode range, output range (does it go rail to rail?), case style, etc. etc. How about MOSFETs? Does the site do any better here? Well, the parameters available are: Vendor, Channel Type (N or P), Channel Mode (Enhancement/Depletion), Configuration. So, that'll be a no then! What about Vds max, Rdson, max current, max power, Qrr, Qg, Ton, Toff, case style, etc. etc.? I did manage to find an active device with at least one useful parameter to search: Peak Reverse Repetitive Voltage for rectifiers. However, this is not in numeric order. It also appears that you cannot select more that one item in the list (if you need a Vrrm of at least 100 V, that doesn't mean you need *exactly* 100 V, so it's useful to be able to select a range.) Finally, it does not appear to be possible to link directly to a product category (e.g. Semiconductor : Discrete : Rectifier), as the URL remains http://www.datasheets.com/search/ProductLineAction.do. This means I can't bookmark specific categories and have to drill down from the top each time I want to perform a new search. If SiliconExpert figure out how to normalise the specs that actually matter, across all devices on the market, that would be truly amazing. However as it stands I'm afraid from my perspective the site really doesn't live up to the promise of your post.

Hi HD, Product Marketing Manager from SiliconExpert here (the data service behind datasheets.com). Datasheets.com at present lists 4-6 parametric filters per category. We're actively seeking user feedback to make sure the most relevant filters are shown per category. As Patrick has mentioned, this is a work in progress and we expect to roll out an update in the next 7 days that enhances the relevancy of the filters even more. That said, we've already started to fix the alpha-ordering of numeric parametric options that are listed on the site currently. They should definitely be listed in ascending order as you've mentioned. These fixes are coming as well. As far as selecting multiple options per filter is concerned: we will definitely consider allowing this in subsequent releases. We've found it's far easier for some users to select a single filter and have the site refresh the filtered parts. This is of course up to debate and several distributor websites are taking a different approach. We'll keep monitoring feedback to see if we should head in this direction. Your feedback is certainly appreciated and we will be incorporating a lot of these suggestions. Thanks.

Rene, nice catches. We're rolling out an update to the site that fixes the alpha-sorted issues for the parametric values. In addition, more relevant parametric options will also be added based on user feedback. We will definitely consider adding more than 4-6 parametric options per category. Stay tuned and let us know of further suggestions & feedback. We're all ears.

Hi hm, we hear you loud & clear. An update to the site is upcoming that will add more relevant parametric filters per category. Stay tuned and let us know of any further suggestions.

Hi Duane, thanks for the comments. As mentioned in this thread already, we're rolling out an update that will increase the relevancy of the parametric filters per category. That said, we're considering adding more parametric options per category as well. This has definitely been a popular request and we'll be considering it seriously in the next few weeks. Have you had a chance to compare two parts on the site yet? Would be curious to hear your perspective on how this feature performs for you.

I took a quick look at the comparison between two MCUs. Did you make some updates last night? Yesterday, I wasn't getting results when searching for Microchip MCUs. Today, it worked fine though. I always find it a bit of a challenge to select between the nearly identical PIC family members. I compared "PIC18F2321" and "PIC18F2331". The vertical arrangement of the comparison data makes it easy to scan. I find it a lot easier than having to scroll horizontally. What I find really nice is that when parameters are the same, they are in one common column. It's only the differing specs that are in separate columns. This makes it MUCH easier to quickly scan and determine which one I should pick.
