399-40-156-10-009000

Headers, Male Pins Overview

The Mill-Max Manufacturing Corp. model 399-40-156-10-009000 is a vertical pin header connector designed for through-hole mounting on printed circuit boards. This component belongs to the 399 series and features a dual-row configuration with 56 contact positions. The connector utilizes a standard 0.100-inch (2.54 mm) center-to-center spacing between pins. It is constructed with gold-plated contacts over a nickel barrier to ensure reliable signal transmission and corrosion resistance. The housing is made of black polyphenylene oxide (PPO) thermoplastic, providing high thermal stability and flame retardancy compliant with UL 94 V-0 standards. The unit is supplied in bulk packaging for automated assembly processes.

Headers, Male Pins Procurement Notes

Verify that the specific suffix codes match the required plating thickness and contact length specifications for your application environment. Confirm RoHS compliance status if restricted substances are a concern. Ensure the bulk packaging format aligns with your pick-and-place machine capabilities. Cross-reference the datasheet for precise mating force requirements and operating temperature ranges before finalizing the bill of materials.

Headers, Male Pins Selection Notes

Select this part when a 56-position dual-row header is necessary within a 2.54 mm pitch constraint. Consider the gold plating option for environments prone to oxidation or where low contact resistance is critical. Evaluate the mechanical retention strength provided by the through-hole pins against vibration requirements. Compare the overall height and insulation properties against adjacent components to ensure proper clearance and thermal management during operation.
