Frequently asked questions
Where can I buy Molex 22-28-4178 and how do I get a price?
Submit an RFQ with your target quantity; we confirm availability and current pricing at quote time. No stock-holding claim is made — each order is confirmed against the BOM line.
What is the difference between 22-28-4178 and 22-28-4170?
The primary difference is circuit count: 22-28-4178 is a 17-circuit header, while 22-28-4170 is a 10-circuit header. Both are KK 100 breakway style with 30 µinch gold plating and share the same 0.100-inch pitch. The 17-position version is the one to use when your BOM calls for 17 positions.
