DF3EA-3P-2H(51)

Headers, Male Pins Overview

The DF3EA-3P-2H(51) is a surface mount right-angle header from the Hirose DF3 series, featuring a 2.00 mm pitch and three positions. It utilizes brass contacts with an 8.00 µin (0.203 µm) gold plating for reliable signal transmission. The connector operates within a temperature range of -55°C to 105°C and supports a rated voltage of 250VAC. Constructed with beige polyamide insulation rated UL94 V-0, it includes a four-wall shroud and fixed solder tails for secure PCB mounting.

Headers, Male Pins Feature Summary

• Features a friction-lock mechanism to ensure firm mating connections with compatible DF3 slots.
• Incorporates reinforced metal fixtures on both sides of the housing to prevent solder joint peeling.
• Includes PCB mounting tabs for precise positioning during the soldering process.

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board connections
• General electronic circuit assembly

Headers, Male Pins Procurement Notes

Verify that the specific suffix (51) corresponds to the required contact plating thickness and material composition as defined in the official datasheet. Confirm that the surface-mount right-angle configuration aligns with the target PCB layout requirements before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile, right-angle SMT header with a 2.00 mm pitch is required. Ensure compatibility with the corresponding DF3 series mating slot connectors. Consider the thermal operating limits and insulation material properties relative to the intended application environment.

Headers, Male Pins Part Context

This part belongs to the DF3 series of 2.00 mm pitch connectors designed for compact electronic assemblies. The DF3EA variant specifically denotes the surface-mount right-angle header configuration. It is engineered for high-density applications requiring robust mechanical locking and reliable electrical performance in space-constrained designs.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Hirose DF3EA series headers with matching pitch and position counts, such as DF3EA-3P-2H(21), provided the contact plating specifications meet the design requirements.
