JST EH vs XH

The JST EH and XH connectors stand out as popular choices for 2.5mm pitch applications. Both are reliable, compact, and widely used—but they’re not identical. So, how do you decide between JST EH and XH for your next project? In this post, we’ll break down their features, differences, and ideal use cases to help you choose.

Overview of JST EH Connectors

The JST EH series is designed for high-density connections where space is at a premium. With a 2.5mm pitch and a slim, shrouded header, it’s a go-to option for compact PCB layouts. Rated at 3A and 250V AC/DC, the EH connector delivers solid performance in small packages. Its low-profile design ensures secure mating, while the shrouded header prevents misalignment—perfect for applications requiring precision.

Best for:

• Compact electronic devices like wearables or sensors.
• PCBs with tight spacing where every millimeter counts.

Overview of JST XH Connectors

The JST XH series also uses a 2.5mm pitch but offers a slightly different approach. With a low mounting height of 9.8mm and a compact yet versatile design, XH connectors strike a balance between size and adaptability. Like the EH, they’re rated at 3A and 250V AC/DC, making them equally capable in terms of power. The XH’s design prioritizes ease of use and compatibility, which has made it a staple in a variety of industries.

Best for:

• Consumer electronics like TVs or appliances.
• Power supply units or general-purpose wiring needs.

Key Differences Between JST EH and XH

While JST EH and XH connectors share some traits, their distinctions are critical for your project:

• Size and Profile: The EH is slimmer and more compact, perfect for cramped PCB designs. The XH, though still small, has a slightly larger footprint with a low-profile height of 9.8mm, suited for broader applications.
• Mounting Options: The EH is available only in a through-hole version, limiting it to traditional PCB mounting. The XH offers both through-hole and surface-mount (SMT) versions, providing more flexibility in assembly.
• Use Case Focus: EH is tailored for space-constrained, high-density environments, while XH adapts to a wider range of setups.

Conclusion

So, JST EH or XH—which is right for you? It hinges on your project’s needs. The EH, with its slim design and through-hole mounting, is ideal for tight PCB layouts. The XH, with through-hole and SMT options, offers greater flexibility for diverse applications. Both deliver reliable performance, so matching their strengths to your design is key.
