What is the difference in part number [0217005.HXP](https://www.digikey.com/en/products/detail/littelfuse-inc/0217005-HXP/777111?s=N4IgTCBcDaIAxgIwHY5wKwDoASANACiALoC%2BQA) , [0217005.MXP](https://www.digikey.com/en/products/detail/littelfuse-inc/0217005-MXP/777549?s=N4IgTCBcDaIAxgIwHY5wKwDoCyANACiALoC%2BQA) and [0217005.VXP](https://www.digikey.com/en/products/detail/littelfuse-inc/0217005-VXP/3425419?s=N4IgTCBcDaIAxgIwHY5wKwDoBqANACiALoC%2BQA)? ---

The difference in these part numbers is the factory packaging. While all of the parts are available in quantities of one from Digi-Key, when Digi-Key orders them from the manufacturer part number for example 0217005.VXP is ordered in package quantities of 5. The 0217005.HXP is ordered in package quantities of 100 and 0217005.MXP is ordered in a package quantity of 1,000. Further Breakdown of part 0217005.HXP would be as follows 0217 would be the series number 005 would be the rating of 5 Amps H would he MFG pack of 100. (Digi-Key sells individually) X would be filler (or Bulk) P is the RoHS identifier ![image](https://global.discourse-cdn.com/digikey/original/3X/1/9/19dc7fbabd405e4d6530cfb13cc865991eee409c.png) Additional options for pack quantity would be as follows X=1 V=5 T=10 S=20 L=50 H=100 F=200 G=250 U=500 M=1000 D=1500 P=2000 E=2500 W=3000 Y=4000 N=5000 K=10000 J=12000 Z=MISC Additional Packaging Types A= Ammo Packed B= Bubble packed C= Chip Packed R= Reeled X= Filler > [@Littelfuse HXP vs MXP Suffixes](https://forum.digikey.com/t/littelfuse-hxp-vs-mxp-suffixes/326): > > One common question we get here at Digi-Key is what is the difference in the HXP and MXP suffix when looking at [Littelfuse](https://www.digikey.com/en/supplier-centers/l/littelfuse) cartridge fuses. For this example I will look at Littelfuse part number 0218005.HXP (Digi-Key [F2422-ND](https://www.digikey.com/en/products/detail/littelfuse-inc/0218005-HXP/777138)) and 0218005.MXP (Digi-Key [F1748-ND](https://www.digikey.com/en/products/detail/littelfuse-inc/0218005-MXP/777604) These parts are actually the exact same part. The HX is calling out a factory package of 100 pieces and the MX is calling out a manufacturing standard packaging of 1,000 pieces. Both parts are sold individually here at Digi-Key. Here is …
