| MC2Short:
I found a picture I had of those top two sot23's, but I can't figure out what they are.. The top one especially is hard to read to me. I also found a pretty good picture of the bottom four. Looks like 6B> or something along those lines. I think the 6B> might possibly be a BC817-25, but I'm not sure. After doing a lot of reading I think the CXQPI is a IRLML6302 And I think the M1L one is a NSVMMBT6429LT1G but if anyone else has a opinion on what it might be please let me know |

This is true. |

From another picture it looks as if pin1 is NC on these, but if there is a trace under the body of the device then everything makes sense and BC817-25 will work just fine as will many other NPN transistors. You've done some pretty good part number research. I think your conclusion on the M1L is correct. Your ID of the CXQPI is interesting and a plausible reason for the meter to stop functioning. What did you read and how did you come to find the IRLM6302 number? |
| MC2Short:
I apparently got them right because I ordered those sot23s and now my fluke 175 works perfectly again. I'm amazed really. |
| MC2Short:
I used this for identification for the CX sot23 |
