When designing compact electronic systems, choosing the right connector can make or break your project. Two popular options in the 1.25mm pitch category are the Molex PicoBlade and the JST GH. Both are widely used in small-scale applications, but they cater to slightly different needs. At Zeakka Electronics, we understand the importance of precision and compatibility, so let’s break down these connectors to help you decide which fits your design—and how our alternatives can save you time and cost.
Overview of Molex PicoBlade
The Molex PicoBlade is a versatile 1.25mm pitch connector available in both wire-to-board and wire-to-wire configurations. It features a secure friction-lock mechanism and supports through-hole or surface-mount (SMT) headers. Compatible with wire gauges from 26 to 32 AWG, it’s built for durability, making it ideal for high-vibration environments like automotive or industrial applications. Its compact size also suits space-constrained designs.
Overview of JST GH
The JST GH, also with a 1.25mm pitch, is a wire-to-board-only connector designed for lightweight, SMT applications. It includes a locking tab for secure mating and supports 26-30 AWG wires. Known for its use in drone electronics and compact consumer devices, the GH prioritizes simplicity and reliability in surface-mount setups where weight and space are critical.
Comparison
Let’s dive into the specifics to see how these connectors stack up:
| Feature | Molex PicoBlade | JST GH |
|---|---|---|
| Pitch | 1.25mm | 1.25mm |
| Connection Type | Wire-to-board, wire-to-wire | Wire-to-board only |
| Locking Mechanism | Friction lock | Locking tab |
| Mounting Options | Through-hole or SMT | SMT only |
| Wire Gauge | 26-32 AWG | 26-30 AWG |
| Durability | High (vibration-resistant) | Moderate (lightweight focus) |
At Zeakka Electronics, we offer cost-effective, high-quality alternatives to both Molex PicoBlade and JST GH connectors.
Use Cases
- Choose Molex PicoBlade if your project requires versatility (wire-to-wire or wire-to-board), durability in harsh conditions, or through-hole mounting. Think automotive sensors or industrial controls.
- Choose JST GH for lightweight, SMT-only designs where space and weight are top priorities, like drones or portable consumer electronics.
Conclusion
The Molex PicoBlade and JST GH both shine in compact applications, but your choice depends on your project’s needs. Need flexibility and ruggedness? Go with PicoBlade. Prioritizing lightweight SMT designs? GH might be your pick. Whatever you decide, Zeakka Electronics is here to support you with reliable alternatives.
