Practical resources for selecting, comparing, testing and applying electronic connectors and wire harnesses.
Connector Selection Guides
Compare pitch, contact count, mounting style, mating direction and wire termination options before choosing a connector family.
Connector Specifications
Use this section to understand pitch, current rating, voltage rating, insulation dimensions, wire size, rows, series and mating height. Always confirm final values against the manufacturer datasheet.
JST, Molex and Hirose Cross-Reference
Find compatible connector families, alternatives and replacement considerations by series, pitch, configuration and application constraints.
Testing and Quality
Review continuity, crimp quality, pull force, insulation, dimensional inspection and sample validation practices for reliable assemblies.
Industry Applications
Explore connector and wire harness considerations for automotive, industrial equipment, renewable energy, consumer electronics and other applications.
Custom Wire Harness Solutions
KONNRA supports custom connector and wire harness assemblies from component selection through sample validation and production.
Frequently Asked Questions
How do I choose a connector?
Start with electrical requirements, pitch, space, mating cycles, environmental conditions and wire or PCB termination requirements.
Can I replace a JST, Molex or Hirose connector with another series?
Only after checking mechanical fit, electrical ratings, terminal geometry, tooling and compliance requirements. A similar pitch alone does not confirm compatibility.
What should I request before approving a sample?
Request the datasheet, drawing, material details, test results and a sample that matches the intended wire, PCB and enclosure conditions.
