How can I obtain a reliability report?
- From the product's QuickView data sheet, click on the "Technical Documents" tab. Scroll down to the Reliability Reports heading.
- Go to www.maximintegrated.com/reliability-reports (or search for "Reliability Reports").
- If no reliability report is listed, you can request a custom reliability report from our Reliability Department. Go to www.maximintegrated.com/reliability-reports (or search for "Reliability Reports") and "request a customer reliability report."
I cannot find a reliability report on your website for the part that I am using. Is there a similar device with a reliability report that I can use?
No, every device is different. If you do not find a reliability report for a part, you can request a customized reliability report from our Reliability Department. Go to www.maximintegrated.com/reliability-reports
(or search for "Reliability Reports") and "request a customer reliability report."
Orders and Samples
I have some Maxim parts in stock. I want to know if they are authentic Maxim parts. How can I do that?
It is often very hard to identify counterfeit parts. The only way to be certain is to purchase parts from Maxim Direct or an authorized distributor. Authorized sales channels can be found at: www.maximintegrated.com/sales
I ordered some parts from Maxim Direct and still have not received the parts. I suspect a problem. How do I check my order?
You can view your Order Status through Maxim Direct's online store. Use the MyOrders link on the Maxim Direct page: http://shop.maximintegrated.com/

A "-W" indicates a waiver. Contact Customer Service for additional information: www.maximintegrated.com/sales
What do other part-number suffixes, including lead-free and RoHS markings, mean?
The most common suffix letters in a part number denote package, temperature range, and other options:
- A "+" symbol indicates that the part is qualified as lead-free. The + symbol is also marked on the package.
- A "#" symbol indicates that a part is RoHS-compliant and exempt from lead-free requirements. The # symbol is also marked on the package.
- A "T" or "T&R" indicates that the part is furnished on tape-and-reel.
- A "D" indicates dry pack (for parts not Moisture Level 1).
- For parts with DS prefix, "-U/+U" signifies cut tape.
Additional suffix codes are described in general terms at: www.maximintegrated.com/qa/info/naming_conventions/
Suffix codes for a particular part are detailed in the full data sheet. To find the data sheet, go to the QuickView for the device.

General and Miscellaneous
Does Maxim make an "exact cross" for my part?
Use the cross-reference search at www.maximintegrated.com/xref
to find Maxim replacements. Enter the part number for the industry-standard device and submit the query.
Make sure to download both data sheets (the industry-standard and the Maxim) to ensure that you select the same package type.

Can I get the hybrid reflow solder profile? What is the maximum reflow temperature?
The Maxim RoHS/Lead-Free Lookup site is: www.maximintegrated.com/leadfree
. From there, click on Lead-Free/RoHS FAQ in the list at the left edge of the page (www.maximintegrated.com/emmi/faq.cfm
) to obtain solder reflow profiles for both lead-free and leaded components.
What is the difference between RoHS and lead-free?
RoHS compliance means that the part is free of lead, cadmium, chromium, mercury, PBBs, and PBDEs. Lead-free means that the part is free of lead, specifically.
No Maxim processes or parts use or contain cadmium, chromium, mercury, POBBs, and PBDEs. All our parts are "5 of 6" compliant. Lead is the only substance that applies to Maxim parts.

Do you have a "5 of 6" compliance document?
Yes. Go to: www.maximintegrated.com/emmi/rohs_info.cfm
What is the thermal impedance (thermal resistance) for my part? Theta-JA (ΘJA), Theta-JC (ΘJC)?
Theta-JA and Theta-JC are both package-dependent numbers. If the information for a particular package is not in the Absolute Maximum Ratings in the product data sheet, contact Applications Engineering/Technical Support: www.maximintegrated.com/support
. This information will be researched upon request.
For more information, see application note 4083, "Thermal Characterization of IC Packages
," and application note 4186, "Thermal Design Considerations for Video Filters
I saw your new part advertised but cannot find the data sheet. Why?
Occasionally a part number is advertised or listed on the website, but a data sheet is not available for download because of the highly proprietary nature of that product. In those cases, request the data sheet by completing the "Request Full Data Sheet" form in the product QuickView, and wait for a response.
If you enter a part number into the "Part Number Search" engine and get no results whatsoever, the part could be a "future" device, a product not yet introduced. In those cases, contact Applications Engineering/Technical Support: www.maximintegrated.com/support
I want to build my next boards with a 3.3V version of the 5V part that I am already using. The package will be the same. What do you recommend?
Check the current version of the data sheet to determine if "Next Generation" devices are mentioned on the front page.
Use the parametric search engine on the website at: www.maximintegrated.com
. Then Click on "Parametric Search/Product Trees" and search for the part.
