Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific part number matches the required 28-contact configuration and 2.54 mm pitch. Confirm compatibility with 0.635 mm square profiles before integration. Ensure environmental ratings meet operational requirements, specifically the -40°C to 200°C range. Check surface finish specifications against soldering or mating connector standards. Validate material certifications if UL94 V-0 flammability rating is critical for the application.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-count, low-profile connection is needed for square profile interfaces. Consider the 3 A current rating and 250 V AC voltage limits for circuit design. Evaluate the tin-plated contact surface against mate connector materials to prevent galvanic corrosion. Assess the need for high-temperature performance exceeding standard industrial limits. Compare volume resistance requirements against system signal integrity thresholds.
