15916403 is listed in the Headers, Male Pins range at ChipApex. The manufacturer field lists Molex. Its product description is CONN HEADER SMD 40POS 2.54MM. Review the specifications below when checking this part for your BOM.
Molex part number 15916403 is a tool head assembly designed for use with Molex pneumatic crimping systems. It is specifically engineered to work in conjunction with the compatible base tool unit, identified as Molex part number 19279-0001. This component serves as the functional interface that applies pressure to terminals during the crimping process. The assembly is intended for use with specific terminal series within the Molex product portfolio, ensuring consistent mechanical deformation of the contact and insulation areas. As an interchangeable accessory, it allows for adaptation of the primary tooling system to different terminal geometries or wire gauge requirements without replacing the entire pneumatic actuator mechanism.
Verify compatibility with the specific terminal series required for your application before procurement. Confirm that the host tool unit matches the designated compatible model, specifically part number 19279-0001, to ensure proper mechanical fit and operational safety. Check current availability status as inventory levels for specialized tooling accessories may fluctuate. Ensure storage conditions are appropriate to prevent damage to the precision components within the assembly prior to installation.
Select this tool head only if the existing infrastructure utilizes a compatible Molex pneumatic press system. Evaluate the specific terminal geometry and wire range requirements against the official specifications for this head assembly. Consider maintenance schedules and replacement cycles for tool heads to minimize downtime. Verify that the pneumatic supply parameters meet the operational requirements of the host tool unit to ensure consistent crimp quality.
This component belongs to the broader category of application tooling provided by Molex for electrical connection assembly. It functions as a specialized accessory rather than a standalone device, relying on a primary actuation source. The part is distinct from manual hand tools or electric press mechanisms, focusing specifically on pneumatic integration. Its role is critical in maintaining consistency in crimp formation across high-volume production environments where standardized force application is necessary.
When replacing a worn or damaged tool head, ensure the new part number matches exactly to maintain dimensional accuracy. Cross-reference with official Molex documentation to confirm no design revisions have altered the interface dimensions. Avoid using generic aftermarket equivalents unless explicitly verified for compatibility with the 19279-0001 base unit.
