Your component has part number 0874272442 (according to digikey) which is well not covered at all bei the pdf and also not by the part numbers listed in the description. The footprint description states that this part is valid for the following order numbers 5566-24A, example for new mpn: 39-28-x24x As per datasheet So all guarantees vanish if the order numbers do not agree fully. At least the official library is likely to be better than what a single person can achieve as every contribution is double checked (It is very rare that i get a contribution where i do not need to request some changes).Įvery footprint is checked against exactly one data sheet entry and therefore guaranteed to be valid for this one order number. I generally think this is a bit of an overreaction. For those of us doing simple projects we get the parts and print out the board to check sizes before ordering the board. One post that sticks with me from the EEVBLOG site is a pro that said he does 100% of his own footprints because he can’t afford for them to be wrong. Then came automobile tires many of which sizes combine metric and inches.If I remember correctly, we Americans started this Integrated Circuit nonsense with DIP pins on 0.1 inch centers, but then the Europeans went and confused matters by introducing metric spacing.But with persistence and moderate force a user could momentarily mis-connect 2-3 pins of the mating the male and female, causing my carefully-designed charger to go POOOOOOF! In theory this was a polarized connector which could be plugged in only one way. Besides the example of 5.0 vs 5.08 mm pin spacing with which you might be able to mount the wrong one if the connector has only 2-3 pins: I once designed a battery charger with a circular DIN output connector (I think it was 5 pins). They are a case in point for my philosophy of life and engineering, which states that everything is more complicated than you think. ![]() Connectors are probably the most cumbersome and error-prone parts for PCB design.
