Frequently asked questions
Is the 640505-1 RoHS compliant?
Yes, the 640505-1 is RoHS compliant, suitable for lead-free assembly processes.
What is the mating connector for the 640505-1?
This is a male header designed for board-to-cable/wire applications. It mates with a corresponding MR series female receptacle housing and crimp terminals (not included). Confirm the mating half part number based on your wire gauge and circuit count.
What is the replacement or equivalent for the 640505-1?
No direct replacement is listed by the manufacturer. The peer 1318699-3 is a 12-position, gold-plated alternative with the same pitch and latch lock, but half the circuit count. For a 24-position equivalent, verify compatibility with other MR series headers.
