JST Connector Types: Complete Guide to PH, XH, SH, and Every Series
Important: “JST-style” is not a specification. Choose the housing, terminal and header from the same approved JST series, then confirm the exact wire range and derating in the applicable data sheet.

DuPont vs JST vs IDC: Prototype to Production Connector Guide
Migration rule: A 2.54 mm prototype header cannot be exchanged for a JST or Molex connector without a PCB and harness change. Verify footprint, header orientation, keying, terminal and cable assembly together.

Crimp Tool and Crimping Quality Guide: Getting Reliable Terminations
Do not use the numeric crimp-height examples in this article as production release limits. The correct height, pull requirement and visual criteria come from the selected terminal’s manufacturer drawing and the approved applicator setup.

Crimp vs IDC vs Solder: Wire Termination Methods Compared
Quality rule: A reliable termination is defined by the connector manufacturer’s approved terminal, wire, applicator and inspection criteria—not by a generic crimp height or a visual impression alone.

Box Header vs Pin Header: When a Shrouded Connector Is Worth It
Box Header vs Pin Header: When a Shrouded Connector Is Worth It A box header is essentially a pin array surrounded by a molded shroud. That extra housing increases footprint and cost, but it can also protect contacts, guide mating, support polarization and provide a latch. The right choice depends less on the electrical schematic […]

Board-to-Board Connector Selection Guide: A Practical Engineering Workflow
Board-to-Board Connector Selection Guide: A Practical Engineering Workflow Choosing a board-to-board (B2B) connector is not simply a matter of matching pitch and pin count. The connector also defines board spacing, assembly tolerance, serviceability, signal integrity, current density and, often, the mechanical architecture of the enclosure. This guide turns those requirements into a practical selection workflow. […]
