Greetings-Trying to build 4 MR-16s, and several parts are on back-order with Mouser. I have found what appears to be some replacement parts, but I wanted to check with everyone to see if I am on the right track. Part #1: Oscillators DIP-8 5V 40MHz (Mouser #520-TCH4000-X). Replacement Part from Digi-Key: You are not allowed to view links. Register or LoginPart #2: IC & Component Sockets 8P ECONOMY TIN (Mouser #571-1-390261-2). Replacement Part 3M Socket from Mouser #517-4808-3004-CP: You are not allowed to view links. Register or LoginPart #3: LED Drivers 4096 Step Grayscale LED Driver (Mouser #595-TLC5940NT). According to Mouser, this part will be shipped 10/26/2009. Replacement Part Sierra IC has 481 of these You are not allowed to view links. Register or Login in stock but you have to call for the price (listed as $6.21 from Optopart.com). Questions: Would these replacement parts work? Where else might I look? For Part #3, would it be better to take a chance and wait on Mouser or pay the extra $2/part for the parts from Sierra? Finally, have others had good experiences with Digi-Key and Sierra as vendors? This is my first time attempting to locate alternatives, so thanks in advance for your help!Terry
Thanks, RJ. I fixed the link on Part 3, so it should work now. I appreciate the feedback on both parts and vendors. BTW, I got the replacement heat-sink yesterday, and it's a perfect fit. Thanks, again!Terry
fixed the link on Part 3, so it should work now.
Did you find a vendor that has any available, all the vendors I checked were back-ordered?
Might the TLC5941NT work? It appears similar but I've not dug into the details. Larry

Is the EPROM feature needed or are we just driving the MOSFETs via instructions from the PIC?I'd like to get more of a definite "yes" from the man himself before I just order the new chips.Got an email from Mouser last night confirming the "expected" 11/30 new ship date...
