10-88-1121

Headers, Male Pins Overview

The Molex 10-88-1121 is a male pin header from the KK 508 Connector System, designed for board-to-board and wire-to-board applications. It features a 2.54mm (0.100 inch) pitch with 12 positions loaded in a dual-row configuration. The connector utilizes round pins with tin plating on both mating and termination interfaces. Rated for 3.00 A at 250 V DC, it supports up to 7A per circuit in wire-to-board setups. The housing is made of natural polyester resin with UL 94V-0 flammability rating. Operating temperature range is not explicitly defined in provided data, but standard industrial ranges typically apply.

Headers, Male Pins Feature Summary

• Round pin design for reliable board-to-board and wire-to-board interconnections
• Dual-row through-hole mounting for secure PCB attachment
• Tin-plated contacts ensure corrosion resistance and stable conductivity
• UL 94V-0 rated natural polyester housing for flame retardancy

Headers, Male Pins Applications

• Board-to-board interconnects in consumer electronics
• Wire-to-board connections in industrial control systems
• Signal and power distribution in automotive sub-assemblies
• General-purpose PCB headers in data communication equipment

Headers, Male Pins Procurement Notes

Verify that the ordered part matches the exact KK 508 series specification. Confirm terminal count is 12 positions and pitch is 2.54mm. Ensure tin plating is specified if environmental resistance is required. Check compatibility with mating sockets from the same series. Validate UL certification status for your specific application region.

Headers, Male Pins Selection Notes

Select this header when a robust, high-current board-to-board solution is needed. The 7A capacity suits power-heavy designs. Tin plating offers cost-effective performance for non-corrosive environments. For higher current or harsh conditions, consider gold plating alternatives. Ensure PCB hole diameter matches the round pin size for proper retention.

Headers, Male Pins Part Context

The KK 508 system is a widely used connector family known for reliability in demanding applications. This specific part represents a standard pin header variant within that ecosystem. It complements matching sockets and crimp terminals sold separately. The design prioritizes mechanical stability and electrical consistency across diverse industries.

Headers, Male Pins Replacement Considerations

No public confirmed substitute part numbers are available in the source material. Cross-referencing with other manufacturers requires independent verification of pin dimensions, pitch, and current ratings.
