JST 2.0 mm connectors are a top pick for engineers needing compact, reliable solutions. With a 2.0 mm pitch, they suit wire-to-board and wire-to-wire uses in consumer electronics, automotive, and industrial automation. This post covers four key types—JST PH, PA, PHD, and PUD—to match your project, from battery packs to high-density systems. See how they can power your next design with Zeakka Electronics’ expertise.
JST PH
- Pitch: 2.0 mm
- Category: Wire to board, wire to wire (JST doesn’t offer wire to wire, we do)
- Pin Numbers: 2 to 16 circuits (single row)
- Current (Max): Up to 2 A
- Voltage (Max): 100 V
- Orientation: Straight and right angle
- Mounting type: SMT, THT
- Alternative: Zeakka 2002
The JST PH connector is a go-to for engineers needing a small yet reliable wire-to-board solution. With its 2.0 mm pitch, this single-row connector is designed for high-density, low-profile applications. You’ll find JST PH connectors in battery packs for portable devices, 3D printers, and small consumer electronics where space and efficiency are critical. Its crimp-style design ensures secure connections without bulk, offering a balance of simplicity and performance.
JST PA
- Pitch: 2.0 mm
- Category: Wire to board
- Pin Numbers: 2 to 16 circuits (single row)
- Current (Max): Up to 3 A
- Voltage (Max): 250 V
- Orientation: Straight and right angle
- Mounting type: SMT, THT
- Alternative: Zeakka 2001
For projects requiring a bit more robustness, the JST PA connector steps up with a secure locking mechanism. This 2.0 mm pitch connector works for both wire-to-board and wire-to-wire setups, offering flexibility across applications. The locking feature ensures connections stay firm, even under stress, making it ideal for telecommunications equipment, medical devices, and automotive systems. Engineers value the JST PA for its ability to handle moderate power needs while maintaining a compact footprint, blending security with adaptability.
JST PUD
- Pitch: 2.0 mm
- Category: Wire to board
- Pin Numbers: 8 to 40 circuits (dual row)
- Current (Max): Up to 3 A
- Voltage (Max): 250 V
- Orientation: Straight and right angle
- Mounting type: SMT, THT
- Alternative: Zeakka 2018
The JST PUD connector brings a unique edge with its low insertion force and secure locking system. Another dual-row option with a 2.0 mm pitch, it ranges from 8 to 40 pins, handling up to 3A and 250V in a straight orientation. The low-force design simplifies assembly while the locking mechanism ensures durability, making it a standout for high-volume production lines. You’ll see JST PUD connectors in automotive electronics, robust equipment, and applications where frequent mating cycles are a factor. It’s built for reliability in demanding conditions, offering a practical solution for projects needing both ease of use and lasting performance.
JST PHD
- Pitch: 2.0 mm
- Category: Wire to board
- Pin Numbers: 8 to 34 circuits (dual row)
- Current (Max): Up to 3 A
- Voltage (Max): 250 V
- Orientation: Straight and right angle
- Mounting type: THT
- Alternative: Zeakka 2007
The JST PHD is a dual-row, wire-to-board connector with a 2.0 mm pitch, designed for compact, high-density applications. Featuring a low-profile mounting height of 8.8 mm and a slim 5 mm depth, it supports device miniaturization while saving space. Its box-shaped shrouded header ensures high reliability, making it ideal for efficient, robust connections in space-constrained designs.
Conclusioin
JST 2.0 mm connectors—PH, PA, PHD, and PUD—each bring distinct strengths to the table. The PH excels in compact, low-profile designs, while the PA offers secure versatility. The PHD tackles high-density needs with power, and the PUD combines low-force assembly with rugged reliability.
