The 4.20 mm pitch sets the PCB footprint and the per-contact current ceiling — at 6 A the temperature rise stays within the UL94 V-0 polyamide housing limits. The post finish is tin-lead (150.0 µin), which mates with standard solder processes but makes the part RoHS non-compliant.
Confirm the receptacle order code against the BOM before committing.
The 640499-4 mates with TE MR series receptacle housings that accept crimp terminals at 4.20 mm pitch.
No. The post finish is tin-lead (150.0 µin), making the part RoHS non-compliant. For RoHS-required builds, evaluate the peer MPNs (1318699-3, 1-1871673-2, 4-1775099-7) for lead-free alternatives.
