Technical Specifications: Understanding Pitch Standards and Certifications

One of the most critical aspects of headers and wire housings is understanding pitch standards—the distance between adjacent connector pins. This determines compatibility with PCBs and mating connectors. The most common pitch sizes include:

Common Connector Pitch Standards for Headers & Wire Housings

Series	Pitch Size	Current Rating	Voltage Rating	Typical Applications	Certification
XH Series	2.54mm (0.1")	3A	250V AC/DC	3D printers, general PCB interconnects	UL, CSA, RoHS
PH Series	2.0mm	2A	100V AC/DC	Consumer electronics, compact devices	UL, RoHS
VH Series	3.96mm	10A	600V AC/DC	Power supplies, high-current applications	UL, CSA
EH Series	2.50mm	3A	250V AC/DC	Industrial controls, automotive	UL, RoHS
GH Series	1.25mm	1A	50V AC/DC	Ultra-compact devices, wearables	RoHS

Certification requirements are equally critical for B2B buyers. Most international buyers require:

• UL Certification: Underwriters Laboratories safety certification is mandatory for most North American and European buyers. This validates electrical safety and fire resistance.

• RoHS Compliance: Restriction of Hazardous Substances directive compliance is required for EU market access. This ensures products are free from lead, mercury, cadmium, and other restricted materials.

• REACH Compliance: For European buyers, Registration, Evaluation, Authorization and Restriction of Chemicals compliance may also be required.

• Operating Temperature Range: Standard range is -25°C to +85°C, but industrial and automotive applications may require -40°C to +105°C or higher ^[3].

Pitch accuracy is the #1 priority when sourcing connectors. Even 0.1mm deviation can cause mating failures. Always request dimensional drawings and verify with calipers before bulk orders. Material certification (UL file number) is more important than price—cheap connectors that fail in the field cost far more in warranty claims. ^[5]
