Key Advantages as a Mill-Max 0257 Alternative
Our pin is designed to be a seamless, drop-in replacement for the Mill-Max 0257, providing comparable electrical and mechanical performance.
- Solderless and Reliable: The press-fit technology creates a gas-tight, permanent connection by cold-welding the pin to the plated through-hole of the PCB. This eliminates the complexities and potential failures associated with the soldering process.
- Dimensional and Functional Match: This pin is a direct functional alternatives to the Mill-Max 0257, allowing for confident integration into your existing designs and PCBs without any modifications.
- High-Quality Stamped and Machined Parts: Our pins feature a precision-machined brass alloy shell with a durable gold-over-nickel plating. This construction ensures excellent conductivity and long-term reliability even in harsh environments.
- Designed for PCB Integrity: Our unique press-fit zone design prevents damage to the internal board layers and maintains continuity throughout all layers of the PCB.
What is press-fit in PCB?
The press-fit technology is a solder-less termination technology used in electrical systems throughout the interconnection industry, which mechanically and electrically joins a press-fit contact to a printed circuit board (pcb).

The basic component used for making electrical connections in a wide array of electronic equipment is the pin receptacle. The JIATEL pin receptacle provides a highly reliable, low resistance electrical path to terminate the pins of a device or discrete wires to aPCB or other mating apparatus such as cables, modules or other pins and wires. Assembled into sockets i.e. DIP, SIP,PGA, etc. or used discretely, receptacles make devices and modules pluggable for repair and replacement. The machined shell or housing of pin receptacles is available in various styles depending on the application, e.g. low profile, elevated, press-fit, SMT. The terminal end of pin receptacles has many variations:a round solder tail, a press-fit tail, a surface mount base, crimp barrel, soldercup,swage feature or no tail.
Inside every JIATEL receptacle is a contact clip. A contact clip is a conductive,multi-finger, progressive die stamping. The standard material is beryllium copper and for high temperature applications, beryllium nickel is used. Both materials are heat treated to achieve optimal spring characteristics & durability.The contact clip engages, scores and holds the mated pin making an electrical and gas tight connection at 3, 4 or 6 points of contact, depending on the selected contact. JIATEL receptacles are capable of 1,000 minimum insertion cycles for a broad range of applications. Mating pin size, shape and
finish, along with application specific variables, will affect the life of a contact.
JIATEL currently offers over 39 styles of contacts to engage pins from 0.008” to 0.102” in diameter.
Pin receptacles can be utilized as discrete connectors for the plugging and unplugging of components on PC boards. They can be utilized individually or in random arrays where the usage is small. They can be handled and loaded manually in preparation for soldering or, with a different style shell, for pressfitting. When the requirement is for volume placement of receptacles, socket carriers or tape and reel packaging are tremendous labor-saving solutions for our customers.
