MDF7-20S-2.54DSA(56)

Headers, Receptacles, Female Sockets Overview

The MDF7-20S-2.54DSA(56) is a single-row receptacle connector from the Hirose MDF7 series, designed for board-to-board applications. It features 20 positions with a 2.54mm (0.100 inch) pitch and utilizes bottom entry termination. The component supports through-hole mounting and employs a push-pull fastening mechanism for secure interconnection. Contact surfaces are gold-plated to ensure reliable signal transmission. The housing is constructed from black polyamide (PA) insulation material rated UL94 V-0 for flammability. Electrical ratings include a current capacity of 3A and a voltage rating of 250VAC, operating within a temperature range of -35°C to 85°C.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix (56) against official Hirose documentation to confirm exact plating thickness and packaging specifications. Ensure compatibility with mating header part numbers within the same MDF7 series family. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a single-row, bottom-entry receptacle is required for board-to-board stacking. The 2.54mm pitch suits standard density layouts. Verify that the 3A current rating meets circuit demands. Ensure the PCB footprint matches the through-hole pin layout and that the push-pull retention force aligns with mechanical constraints.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Hirose MDF7 series, which offers various configurations for board-to-board and mezzanine applications. The series provides options for different pin counts, contact materials, and termination styles. The MDF7-20S variant specifically denotes a 20-position single-row receptacle, distinguishing it from multi-row or header counterparts in the broader product line.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other Hirose MDF7 series receptacles with matching 20-pin counts and 2.54mm pitch, such as MDF7-20S-2.54DSA(55), provided electrical and mechanical parameters align. Cross-series replacements require careful verification of mating dimensions and locking mechanisms.

Headers, Receptacles, Female Sockets FAQ

What is the mating force characteristic of this connector?

The connector utilizes a push-pull fastening type, which typically requires moderate insertion force and provides positive retention upon engagement.
