CH3.96mm & CH5.08mm Connectors and Cable Assemblies
CH3.96mm & CH5.08mm Connectors and Cable Assemblies
This collection covers two separate single-row connector formats: CH3.96mm and CH5.08mm. Its 17 products include housings, crimp contacts, straight and right-angle through-hole PCB headers, component kits, pre-crimped leads and finished cable assemblies.
CH3.96mm and CH5.08mm are not interchangeable. A larger pitch does not by itself establish a higher current rating, heavier accepted wire or suitability for mains power. Select and validate each system independently.
Product Range
- CH3.96mm housings, terminals and straight or bent PCB headers
- CH5.08mm housings, contacts and straight or right-angle headers
- Component kits in selected position counts
- 20AWG and 22AWG pre-wired products in selected listings
- Single- and double-ended colored leads in multiple lengths
- Mixed-family terminal and connector assortments where CH must be selected explicitly
CH3.96mm vs. CH5.08mm
Pitch is measured between adjacent contact centers. The two formats differ in spacing and may also differ in housing profile, latch, contact cavity, terminal and PCB footprint. Never force a 3.96mm housing onto a 5.08mm header or infer compatibility from equal pin counts.
Not PCB Terminal Blocks
The products reviewed here are primarily crimp-housing connector systems and cable assemblies. They should not be confused with screw-clamp or spring-clamp pluggable PCB terminal blocks that happen to use 5.08mm pitch.
How to Select
- Choose CH3.96mm or CH5.08mm from the existing connector or drawing.
- Confirm pitch center to center, position count, housing outline and latch.
- Select housing-only, contacts, PCB header, kit or finished cable.
- For PCB parts, verify footprint, pin dimensions and straight or right-angle orientation.
- Match the terminal to the exact conductor and insulation diameter.
- For cables, check gauge, length, end configuration, conductor order and quantity.
- On mixed listings, confirm the CH option rather than relying on the product title.
Crimping and Pinout
Use an appropriate open-barrel crimp tool. Confirm conductor crimp, insulation support and terminal retention before mating. Check continuity and pin order from the mating face; wire color is not a universal polarity standard.
Electrical and Compliance Boundaries
No collection-wide current, voltage, wire range, material, plating, temperature or certification applies to all products. Claims such as 7A, 10A, 250V, 300V, AWG 12, PA66, UL, RoHS or REACH require product-specific evidence. Final capacity depends on the exact contact, wire, circuit loading, temperature rise and installation.
Typical Applications
Correctly matched parts can support detachable internal wiring in appliances, control boards, LED equipment, power supplies and prototypes. Industrial, HVAC, motor, battery, mains-adjacent and safety-critical uses require independent validation.
Frequently Asked Questions
Can CH3.96mm and CH5.08mm mate?
No. They have different pitch and mating geometry.
Is CH5.08mm automatically rated for more current?
No. Use the exact assembled-system rating.
Are these 5.08mm screw terminal blocks?
No. The reviewed products are crimp-housing connectors and cable assemblies.
Does every kit include housing, contacts and header?
No. Check the selected option and package contents.
Are all products genuine JST parts?
No original-brand claim is made; Yoeruyo is the listed brand.
Ordering Checklist
Confirm pitch, positions, latch, contact, wire size, cable length, pinout, PCB footprint, header orientation, ratings, documentation, contents and quantity. Validate a sample before production use.
