1201088051

Overview

The Molex 1201088051 is a 5-position, double-row, right-angle through-hole header connector from the KK 2.54mm series. It features a 2.54 mm pitch and a 10.92 mm mating height. The housing is constructed from black polybutylene terephthalate (PBT) with UL 94V-0 flammability rating. The connector utilizes gold-plated phosphor bronze contacts rated for 3A current at 85°C. This component is designed for secure PCB mounting and reliable signal or power transmission in compact electronic assemblies.

Feature Summary

• Double-row configuration providing high density in a small footprint
• Right-angle design facilitates efficient board space utilization
• Gold-plated contacts ensure low contact resistance and corrosion resistance
• UL 94V-0 rated PBT housing offers thermal stability and flame retardancy

Applications

• Consumer electronics internal interconnects
• Industrial control system wiring
• Automotive sensor connections
• Telecommunications equipment modules

Procurement Notes

Verify the exact part number against manufacturer datasheets to confirm pin count, row configuration, and plating specifications. Ensure compatibility with mating connectors regarding pitch and housing style. Check for RoHS compliance status if required by your assembly standards. Confirm lead-free soldering requirements align with your manufacturing process capabilities.

Selection Notes

Select this connector when a right-angle, double-row header is required for 2.54 mm pitch applications. Consider the 3A current rating and operating temperature range during design. Evaluate mechanical retention needs, as this is a through-hole component without integrated locking tabs on the housing itself. Ensure PCB layout accommodates the specified body dimensions and hole patterns.

Part Context

This component belongs to the Molex KK 2.54mm family of connectors, widely used for general-purpose interconnections. The series is known for its reliability and cost-effectiveness in mass-produced electronics. The specific model denotes a fixed 5-position variant within this extensive lineup, sharing common mating characteristics with other KK headers.

Replacement Considerations

Compatible substitutes include other 5-position, 2x2.54mm right-angle headers from manufacturers like JST or Samtec, provided they match the pin pitch, current rating, and mounting style. Verify that alternative parts meet the same UL flammability and temperature ratings. Cross-referencing with distributor databases may reveal equivalent components with identical mechanical footprints.
