This article will show you the difference between JST SH connector and Molex PicoBlade connector. And how to identify one from the two.
JST SH connector is NOT the same as Molex Picoblade connector. Don’t use their female and male interchangeably.
JST SH is a 1.0mm pitch wire-to-board connection system. It is only 1.0mm. There is no JST SH 1.25mm connector.
Molex PicoBlade is a 1.25mm pitch wire-to-board, wire-to-wire connection system.
Following is a comparison table of JST SH and Molex PicoBlade connectors.
| attributes \ series | JST SH | Molex PicoBlade |
|---|---|---|
| pitch | 1.0mm | 1.25mm |
| circuit size | 2 - 20 pin | 2 - 15 pin |
| current rating | 1A | 1A |
| voltage rating | 50V | 125V |
| applicable wire (AWG) | 32 - 28 | 32 - 26 |
| configurations | wb | wb |
| single row | YES | YES |
| dual row | NO | NO |
| locking feature | NO | YES |
| through hole type | NO | YES |
| SMT type | YES | YES |
PicoBlade has wire to wire option, but SH doesn’t. PicoBlade has both through-hole type and SMT type headers. SH has only SMT type.
And PicoBlade has a locking feature that can strengthen the mating retention force. SH has no locking feature.
Usually, there is trouble identifying the female housings of the two series. These are three simple ways to identify them.
JST SH connector is 1.0mm pitch. And molex PicoBlade is 1.25mm pitch. The problem is that you might need professional measuring equipment, as it’s almost impossible to tell the difference between 1.0mm and 1.25mm with the naked eye.

Measuring the height is pretty easy to do with a ruler.
The height of JST SH housing (with and without flange) is 5.0mm.
The height of molex PicoBlade housing is 3.95mm.
Check the following pictures of JST SH housing and molex PicoBalde housing (from left to right, SH housing with flange, SH housing without flange, PicoBlade housing – 51021).
You can see that the PicoBlade housing has two locks on the back side. Which SH doesn’t. This is the easiest way to distinguish the two visually.
Note that 2-pin and 3-pin of PicoBlade housing have only one lock. 4-15 pins have two locks.
LDZY Electronics offers both equivalents of JST SH (1001) and molex PicoBlade (1250). Click for more information.
Pitch in connectors, is the distance between the centers of two neighboring pins or contacts in the same row. Size A in the following pictures is the pitch of the connector.
Pitch is an important attribute of connectors. 2.54 mm pitch means the distance between the centers of two neighboring pins or contacts in the same row is 2.54 mm.
Common connector pitches are 0.5 mm, 1.0 mm, 1.25 mm, 1.5 mm, 2.0 mm, 2.54 mm, and 3.0 mm.
You can measure the pitch of connectors with a vernier caliper.
It’s not easy for you to measure the distance between the centers of two neighboring circuits in the same row, as you can’t tell if you are placing the jaws on the vernier caliper in the centers. But we don’t necessarily measure the centers to get the pitch of a connector.
Let’s see how!
For a connector housing, you can measure the edges on the same side of the two holes instead. For instance, measure “B” instead of “A” in the following picture. B = A, so B is the pitch of the connector housing.
Or a connector housing with multiple circuits, you can measure the distance of the two farthest circuits (size “C” in the following picture), and divide it by (number of circuits – 1). For example, the following is a 6-circuits connector housing. You can divide C by 5, the result is the pitch of the connector housing.
For a connector header, you can measure the outer size of two neighboring contacts, and then deduct the width of the contact. For example the connector header on the following picture, the pitch is calculated as B deduct W (pitch = B – W).
If the connector is small and with multiple circuits, you can measure the distance of the number of contacts, deduct the width of the contact, and then divide it by [number of contacts – 1].
For example, the pitch of the connector header in the following picture is (C-W)/4.

In industries where reliability is non-negotiable—think automotive, medical, or industrial automation—cables face constant threats from environmental factors like water, dust, and chemicals. A single failure can lead to costly downtime or safety hazards. That’s where overmolded cable assemblies come in. At LDZY Electronics, we specialize in crafting overmolded solutions that shield your cables from these harsh elements, ensuring performance and longevity. Let’s break down how overmolding provides this critical protection.
Overmolding is a manufacturing process where a protective layer—typically a durable thermoplastic or elastomer—is molded directly over a cable and its connectors. This creates a seamless, sealed barrier that integrates the cable and connector into a single, robust unit. Unlike traditional assemblies with exposed joints or weak points, overmolded cables are built to withstand tough conditions.
Water exposure is a common enemy of electrical systems. Whether it’s rain, splashes, or full submersion, moisture can corrode connectors, short circuits, or degrade insulation. Overmolding solves this by creating a watertight seal around the cable and connection points. Materials like polyurethane or silicone are often used for their excellent water resistance. At LDZY Electronics, we design overmolded cable assemblies to meet specific IP (Ingress Protection) ratings—such as IP67 or IP68—meaning they can handle everything from splashes to prolonged submersion. This makes them ideal for outdoor equipment, marine applications, or washdown environments in food processing.
Dust might seem harmless, but in environments like manufacturing plants or deserts, fine particles can infiltrate connectors, clog systems, and cause wear over time. Overmolded cable assemblies eliminate gaps where dust can settle. The molded layer fits snugly around the cable, leaving no entry points for debris. This is a game-changer for industries like mining or agriculture, where equipment operates in dusty, gritty conditions. With overmolding, your cables stay clean and functional, reducing maintenance headaches.
Cables in chemical plants, labs, or automotive settings often face exposure to oils, solvents, or corrosive substances. Standard cables can degrade quickly under these conditions, with insulation breaking down or connectors failing. Overmolding uses chemically resistant materials tailored to your environment—think PVC for oil resistance or TPE for broader chemical compatibility. This protective layer acts as a shield, preventing substances from reaching the cable’s core. At LDZY Electronics, we work with clients to select materials that match their specific chemical exposure risks, ensuring durability without compromise.
The protection offered by overmolding isn’t just about avoiding failure—it’s about peace of mind. A cable that resists water, dust, and chemicals means fewer replacements, less downtime, and lower long-term costs. Plus, it enhances safety by reducing the risk of electrical faults in critical applications. Whether you’re designing equipment for a factory floor or a medical device, overmolded cable assemblies from LDZY Electronics deliver reliability you can count on.
