MTA-156 -156 [3.96] 48 tyco MTA, CST-100 II, SL-156 and AMP Economy Power (EP) Connectors ANP Flectronics Material and Finish Housing UL94V-0 rated, polyester, white Posts Copper alloy, tin plated, 000030 [0.00076] or .000015 [0.00038] gold over nicke! Notes: 1. Post(s) can be omitted for keying purposes. Specify the desired post(s) to be omitted using the figure to identify Post No. 1. 2. Gold headers are duplex plated, gold on mating end of post and tin on the solder tail. 3. .125 [3.18] solder tail lengths are for .062 [1.57] thick printed circuit boards and .175 [4.45] solder tail lengths are for .093-.125 [2.36- 3.18] thick printed circuit boards. 4. To determine header overall length (Dim. A), multiply .156 x the number of posts. Example: -156 x 10 posts equals 1.560 inches [39.62 mm]. For mateability options, see matrix on pages 34, 35, 54 and 58. For mating half visuals, use connectors with a locking ramp for polarization/retention pur- poses, see pages 36 thru 39, 55, 60 and 62. For polarizing purposes only use connectors without a lock- ing ramp. See pages 36 thru 39, 55, 60 and 62. Header Ordering Information The Base Part Numbers Chart at right shows the base part number and number of posts available for the described headers. Prefixes and suffixes are deter- mined by the number of post positions in the header. For example, the complete part number for a 10-position header with square posts and a .125 [3.18] solder tail length would be: Base number 641208 plus prefix-and-suffix 1- -0 The correct ordering number is 1-641208-0 The set of numbers in bold face are the RoHS equivalent version of the standard prod- uct. Example: No. of Standard Lead Free a oH Pos. Prefix/Suffix Prefix/Suftfix 2 641208-2 3-641208-2 thru 24 -2-641208-4 5-641208-4 See page 15 for an explanation of RoHS lead free equivalents.
