Terminal Blocks – Two-Piece Terminal Block Connectors

Category: Electronics, TE Connectivity, Terminals And Terminal Blocks

Overview

The datasheet presents information on BUCHANAN two-piece terminal block connectors with a focus on right-angle, open-end stacking headers, and right-angle, closed-end headers. Both types have a 5.0 mm centerline and are color-coded for easy identification. They are UL-rated for 300 V, 15 A. Detailed part numbers for varying positions and dimensions are listed, along with their gray, green, blue, and black color variants.

Product Specifications and Part Numbers

The datasheet provides detailed part numbers for both right-angle, open-end, and closed-end header connectors. For every position count ranging from 2 to 10 and dimensions increasing from 10.0 mm [0.394″] to 125.0 mm [4.921″], there are specific part numbers allocated for each color variation of the connectors.

Open-end headers have part numbers such as 1546210-2 for 2-position connectors in gray, and similarly, closed-end headers have part numbers like 1546209-2 for the equivalent product in gray.

Recommended PC Board Layout

Dimensions for the recommended PCB layout are provided in inches, along with corresponding metric equivalents in brackets. The layout is designated for proper accommodation of the terminal blocks.

Replacement Series Information

It is noted that the BUCHANAN Terminal Block Series 372N4HxxT and B73NAHxxT have been replaced with specific part numbers listed as 796698-xx for blue and 796645-xx for black in the case of closed-end headers. The open-end headers list similar replacements with part numbers 796698-xx for blue and 1546179-xx for black variant connectors.

Support and Cross Reference

The document encourages users to contact Technical Support or visit the Tyco Electronics website if required. It also advises that users should refer to a cross-reference starting on page 321 of the document for equivalent Tyco Electronics part numbers.

Footnotes
