A3B-04PA-2DS Datasheet – 2mm Pitch Connector, Hirose

Part Number: A3B-04PA-2DS

Function: 2mm Pitch Miniature Connector



A3B-04PA-2DS datasheet


This is 2mm Pitch Miniature Connector. A3B-04PA-2DS is a type of connector manufactured by JST (Japan Solderless Terminal). It is a 4-position, surface-mount, board-to-wire connector with a pitch of 2.0 mm. The connector consists of a housing and crimp-style contacts that allow wires to be easily connected and disconnected from the board.


1. Miniature Type and High Density Mounting

These connectors are designed in a miniature and light weight product, and mounted in the high density. The crimping case is structured in the 2mm pitch grid, so connectors can be arranged for use.

2. Variation in Number of Contacts

In addition to the dip type, SMT and crimping types a available with broad variations.

3. Stacking Variation

When the connector is used for board to board, set 6 between boards in conjunction with the pin header A or 5.1mm between boards in conjunction with the pin header A3C.

(1) A3B Straight Type
(2) A3B Right Angle Type


1. Current rating : 1A

2. Voltage rating : 200V AC

3. 1. No. of Contacts : 4
