Product details

0.156" Pitch IDC Receptacle for 20 AWG — 6-Position MTA-156

The 0.156" (3.96mm) pitch matches the standard MTA-156 header footprint — a common choice for internal power and signal distribution in appliances, HVAC controls, and industrial panels where the locking ramp keeps the mated pair secure under vibration. The yellow housing is a visual key for the MTA-156 family; the closed-end design and polarizing key prevent wire over-insertion and mis-mating during harness assembly.

IDC Termination and Contact Plating

No stripping, no crimping: one press operation terminates all 6 positions simultaneously. The 80.0µin (2.03µm) tin contact finish is a heavy plating — thicker than the 15-30µin typical on signal-grade IDC connectors — so it handles the higher insertion forces of 20 AWG without galling the contact surface.

Active Lifecycle and Sourcing

Sourcing is straightforward: this is a current-production MTA-156 member. The 6-position count and 0.156" pitch are common — the matching header half (a 6-position, 0.156" pitch, straight or right-angle pin header) is widely available across the TE MTA-156 line. Confirm the header's pin length and orientation to your board stack-up before committing the BOM.

Mating and Field Fit

This receptacle mates with any standard MTA-156 6-position header — through-hole or surface-mount, straight or right-angle — as long as the header uses 0.045" square pins on 0.156" centers. For field replacement: the IDC termination is permanent — you cannot remove and re-terminate a wire in the same slot. If a wire is damaged, the entire receptacle is replaced. The 20 AWG wire gauge is fixed by the IDC slot geometry; using 18 AWG or 22 AWG will not achieve a reliable gas-tight connection.

Frequently asked questions

Where can I buy 3-643818-6 and what is the lead time?

3-643818-6 is an active-production TE Connectivity part. It is sourced to order against an RFQ through independent distribution — availability and current pricing are confirmed at quote time. Submit an RFQ for your BOM quantity to get a delivery commitment.

What connector mates with 3-643818-6?

It mates with any standard MTA-156 6-position pin header that uses 0.045" square pins on 0.156" (3.96mm) centers, with a mating locking ramp and polarizing key slot.

What is the pitch of 3-643818-6?

The pitch is 0.156" (3.96mm), which is the standard MTA-156 spacing between adjacent contact positions.
