What Is the JST SPH-002T-P0.5S?
The SPH-002T-P0.5S is the cable-side female housing in JST’s PH series — 4 positions, 2.0 mm pitch, friction lock. It mates with the B4B-PH-K-S vertical through-hole header, or the S4B-PH-K-S right-angle variant. The compatible crimp terminal is the SPH-002T-P0.5S (reel) or SPH-002T-P0.5L (loose), accepting 22 to 28 AWG wire. Rated 2.0 A per contact at 100 V, with operating temperature from −25 °C to +85 °C. UL listed under JST’s E60389.
The PH series has been a fixture in consumer and industrial electronics since the 1990s. Closest neighbor in the same pitch is Molex’s Pico-Lock 2.00 — but the housings do not interchange. Pico-Lock uses a positive lock; PH uses friction. Pick the wrong header and your harness won’t seat. The other commonly confused part is Molex PicoBlade — same general look, but 1.25 mm pitch, almost half the size. Measure across at least three pin centers before substituting.

Cross-Brand Alternative Connectors
If JST allocation is tight, or you’re trimming BOM cost, several drop-in or near-equivalent options exist. Compatibility tiers below tell you what’s a true plug-in versus what needs PCB redesign.
| Tier | Manufacturer | Alternative Part | Series | Compatibility Notes |
|---|---|---|---|---|
| L1 ✓ | LDZY | 2050-04 | 2050 (PH-equivalent) | Chinese PH equivalent. Drop-in to B4B-PH-K-S footprint. UL E473994 listed. 40–60% cost reduction at scale. |
| L1 ✓ | TONFUL | PH-2.0-4P | PH-2.0 | Marketed as direct PH replacement. 2–3 week lead time when JST sits at 12+ weeks. |
| L1 ✓ | Daier | KF2510 (2.0mm) | KF-2.0 | Common Chinese 2.0 mm housing. Verify mating header dimensions on first article. |
| L2 ⚠ | Molex | 504050-0491 | Pico-Lock 2.00 | Same 2.0 mm pitch and 4 circuits, but positive lock vs PH’s friction lock. PCB footprint redesign needed. |
| L2 ⚠ | Molex | 50058-8400 | Micro-Latch 2.0 | Western counterpart to JST PH per common cross-reference guides. Different latch and key. Not physically interchangeable. |
| L2 ⚠ | Würth Elektronik | 614 004 113 22 | WR-WTB 2.0 | German-made 2.0 mm with similar electricals. Different housing — verify before substituting. |
| L3 ⚠ | Hirose | DF11-4DS-2C | DF11 | 2.0 mm pitch, but dual-row (2×2). Function-equivalent in some board-to-board scenarios, mechanically distinct. |
Where the JST SPH-002T-P0.5S Is Used
Five main applications absorb most of our SPH-002T-P0.5S production volume.
3D Printer Wire Harnesses
De-facto standard for cooling fan headers, hot-end heater cartridges, thermistor leads, and stepper motor breakouts. The 2.0 A rating handles 24 V cooling fans pulling up to 0.5 A with margin. Marlin and Klipper firmware ecosystems both default to PH-style connectors.
Lithium Battery Balance Leads
Standard 3-cell (3S) LiPo balance plug — 4 wires for B−, B1, B2, B+. PHR-5 covers 4S, PHR-7 covers 6S. Friction lock holds well in low-vibration packs; 100 V rating handles series-stacked cell voltages with margin.
RC Hobby & Drone Electronics
Heavy use in ESC-to-receiver harnesses, BEC power leads, telemetry, and powered VTX interconnects in racing drones and FPV builds. Through-hole headers make field repair practical when an RC aircraft needs a re-solder.
Servo & Robotics Wiring
Incremental encoder feedback (5V, GND, A, B), low-current 4-wire stepper breakouts, DC servo control wiring. Drag-chain and AGV applications get high-flex PUR-jacketed builds rated for millions of bend cycles.
Arduino & Maker Boards
Power and signal connector on maker-targeted PCBs. Frequent pick for 4-wire I²C extension cables (VCC, GND, SDA, SCL), NeoPixel/WS2812 LED strip drivers, ultrasonic sensors, Hall-effect rotation sensors.
Industrial Sensor Modules
Smart factory sensors, panel I/O modules, embedded controller interconnects. UL E60389 listing satisfies most industrial-control AVL requirements without re-qualification.
