A-SL127-DG-G54D

Headers, Male Pins Overview

The A-SL127-DG-G54D is a board-to-board connector from the AW 127 series by ASSMANN WSW. It features 54 contacts arranged in two rows with a 2.54 mm pitch. Designed for through-hole mounting, it utilizes straight orientation and solder termination. The housing is constructed from polyphenylene sulfide (PPS) meeting UL 94 V-0 flammability standards. Contacts are made of phosphor bronze with tin plating. Rated for 100V AC and 3A current, it operates within a temperature range of -40°C to 105°C.

Headers, Male Pins Feature Summary

• Dual-row configuration providing high-density connectivity for board-to-board applications
• Through-hole solder termination ensures secure mechanical attachment to printed circuit boards
• Polyphenylene sulfide housing offers robust thermal stability and flame resistance

Headers, Male Pins Applications

• High-density interconnects in industrial control systems
• Signal transmission between daughterboards and motherboards
• Communication equipment internal module connections

Headers, Male Pins Procurement Notes

Verify the exact contact count and row configuration against the specific datasheet before ordering, as suffixes may indicate variations in plating or housing material. Confirm that the through-hole footprint matches the target PCB design. Ensure compatibility with mating header components from the same AW 127 series family to guarantee proper alignment and electrical performance.

Headers, Male Pins Selection Notes

Select this component when a dual-row, 2.54mm pitch connector is required for space-constrained vertical stacking. The 54-contact capacity suits complex signal routing needs. Consider the 105°C operating limit for high-temperature environments. Verify that the phosphor bronze contact material meets the required conductivity and durability standards for the intended application cycle life.

Headers, Male Pins Part Context

This part belongs to the AW 127 series, a line of standard board-to-board connectors from ASSMANN WSW. The series is characterized by its 2.54 mm pitch and through-hole construction. Similar parts in the series vary primarily by contact count and row configuration, offering scalable solutions for different density requirements while maintaining consistent interface dimensions and electrical ratings.

Headers, Male Pins Replacement Considerations

Direct substitutes include other ASSMANN WSW AW 127 series connectors with matching 54-pin, 2-row specifications. Cross-brand replacements require verification of identical 2.54 mm pitch, through-hole mounting, and compatible housing height. Ensure any alternative part maintains the same 100V/3A rating and UL 94 V-0 certification for safety compliance.
