A3B-4PA-2DSA(51)

Headers, Male Pins Overview

The A3B-4PA-2DSA(51) is a Hirose Electric pin header connector from the A3 series, designed for board-to-cable or wire applications. It features a 2 mm pitch with 4 positions in a single row configuration. The component utilizes through-hole mounting with right-angle solder pins and male contact types. Electrical ratings include a current capacity of 1 A and a voltage rating of 200 V. The housing is constructed from black polyamide (PA) material with UL 94 V-0 flammability classification. Contact plating is gold over brass, ensuring reliable conductivity within an operating temperature range of -55°C to +85°C.

Headers, Male Pins Feature Summary

• Right-angle through-hole mounting design facilitates compact PCB layout integration.
• Gold-plated brass contacts provide durable electrical connection performance.
• Polyamide housing offers high thermal stability and UL 94 V-0 flame resistance.

Headers, Male Pins Applications

• Board-to-cable interconnections
• Wire-to-board connections

Headers, Male Pins Procurement Notes

Verify the specific suffix (51) against the latest manufacturer datasheet to confirm packaging quantity and RoHS compliance status. Check for obsolescence notices as A-series components may have limited lifecycle availability. Ensure compatibility with mating sockets regarding locking style and keying features before procurement.

Headers, Male Pins Selection Notes

Select this part when a low-profile, single-row header with a 2 mm pitch is required for right-angle installation. Confirm that the 1 A current rating and 200 V voltage limit meet circuit requirements. Verify PCB hole dimensions match the through-hole pin specifications and ensure sufficient clearance for the right-angle orientation during assembly.

Headers, Male Pins Part Context

This component belongs to the Hirose A3 series, which provides miniature connectors for space-constrained applications. The A3 series shares dimensional similarities with the A4 series but differs in locking mechanisms and specific mechanical features. This particular model represents a standard 4-position variant within the broader product family.
