What the 66564-2 Is — A Stamped Pin for the Multimate III+ System
It is a pin contact — the male half of a connector pair — and carries a tin-lead finish over a brass base material.
Wire Range and Termination — Crimp for 20-24 AWG
The 66564-2 accepts 20-24 AWG stranded or solid wire, terminated by a standard crimp operation. This is a stamped contact, so the crimp wings are formed from the same brass strip as the mating beam — no separate sleeve or machined body. For production crimping, TE recommends a tooling set matched to the Multimate III+ contact family; a hand-crimp tool for low-volume or field repair work is also available through TE's tooling catalog.
Plating and Compliance — Tin-Lead and RoHS Status
The 66564-2 uses a tin-lead contact finish at 50.0µin (1.27µm) thickness. This is a lead-containing plating, which means the part is not RoHS-compliant under the current EU exemption structure for lead in electronic connectors — the exemption for lead in tin-lead finishes on connector contacts expired in 2024 for most applications. Buyers specifying this contact for new designs should verify their RoHS exemption status or consider the lead-free alternative in the Multimate III+ line. The tin-lead finish does offer superior fretting corrosion resistance in high-vibration environments compared to pure tin, which is why legacy avionics and industrial control designs often specify it.
Housing Compatibility — What the 66564-2 Fits
The 66564-2 pin contact is designed for use with Multimate III+ connector housings — both the CPC (Circular Plastic Connector) and the G-Series rectangular housings that accept the standard Multimate III+ contact cavity. The contact is inserted into the housing cavity and retained by a metal locking clip or plastic retainer, depending on the housing variant. For a specific housing order code, match the contact cavity count and keying to the housing series; the 66564-2 is the pin (male) contact, so it mates with the corresponding socket (female) contact in the mating housing half.
Comparing the 66564-2 to the 66564-1
The 66564-2 and the 66564-1 are both Multimate III+ stamped pin contacts with the same 20-24 AWG wire range, brass base material, and tin-lead finish. The difference is the contact finish thickness: the 66564-2 carries 50.0µin (1.27µm) of tin-lead, while the 66564-1 carries 30.0µin (0.76µm). For applications requiring higher mating cycle life or better corrosion resistance in harsh environments, the 50.0µin finish of the 66564-2 is the preferred choice. For cost-sensitive, low-cycle applications, the 66564-1 may be adequate. Both contacts fit the same Multimate III+ housings and use the same crimp tooling.
