Regarding wire-to-wire connectors, there are many options on the market. Choosing the right one for your needs can be daunting, but it’s essential to consider factors such as spacing, voltage, and current rating, installation type, and cost.

Let’s compare the XUNPU WAFER-XH2.54-4PZZ and JST B4B-PH-K-S(LF)(SN) connectors to help you decide which one is right for your project.

Key Differences Explored in Depth

Let’s examine the specifics of wire-to-wire connectors. The disparities between the XUNPU WAFER-XH2.54-4PZZ and JST B4B-PH-K-S(LF)(SN) become more pronounced. Each presents unique advantages tailored to specific application requirements.

1. Spacing:

The spacing between contacts in a connector is crucial in determining its suitability for different wire sizes and overall versatility. The XH2.54 boasts a wider spacing of 2.50mm, providing more room for larger wires.

On the other hand, the B4B-PH-K-S(LF)(SN) features a narrower spacing of 2.00mm, making it a space-efficient option. This difference implies that the XH2.54 might be the preferable choice when dealing with substantial wire gauges, while the B4B-PH-K-S(LF)(SN) excels when saving space is paramount.

2. Voltage and Current Rating:

Understanding connectors’ voltage and current ratings is essential for ensuring they align with the demands of specific applications. Both connectors share a common 2A current rating, signifying their capability to handle a moderate current load. However, a notable distinction arises in their voltage ratings.

The XH2.54 exhibits a higher voltage rating of 250V, making it the superior choice for applications demanding higher voltages. On the other hand, the B4B-PH-K-S(LF)(SN) lags behind with a voltage rating of 100V, rendering it more suitable for low to moderate voltage applications.

3. Installation Type:

The installation type of a connector dictates its attachment method to the printed circuit board (PCB), influencing ease of assembly and overall reliability. The XH2.54 adopts a Dual In-line Package (DIP) configuration, necessitating direct soldering to the PCB.

In contrast, the B4B-PH-K-S(LF)(SN) takes on a surface mount design, allowing for attachment using solder paste and subsequent reflow soldering. Surface mount connectors, such as the B4B-PH-K-S(LF)(SN), generally offer a more straightforward assembly process than their DIP counterparts, potentially streamlining production and reducing manufacturing complexities.

4. Row Number:

The arrangement of contacts in a connector, specifically the number of rows available, determines its capacity to handle multiple wires. The XH2.54 is characterized by a single row of contacts, limiting its capacity for connecting more than two wires.

The B4B-PH-K-S(LF)(SN) can accommodate one or two rows of contacts, presenting a versatile solution for applications requiring connections involving a greater number of wires. This feature expands the applicability of the B4B-PH-K-S(LF)(SN) in scenarios demanding increased connectivity options.

5. Insulation Resistance:

Insulation resistance is a critical parameter, especially in applications where high insulation levels are imperative. The B4B-PH-K-S(LF)(SN) surpasses the XH2.54 in this aspect, boasting a significantly higher insulation resistance of 1,000MΩ compared to the XH2.54’s 100MΩ.

This characteristic positions the B4B-PH-K-S(LF)(SN) as the more suitable choice for applications with stringent insulation requirements, ensuring enhanced reliability and safety in electrical connections.

All in all, the choice between the XUNPU WAFER-XH2.54-4PZZ and JST B4B-PH-K-S(LF)(SN) hinges on the specific needs of the application at hand. Whether prioritizing spacing, voltage and current ratings, installation type, row configuration, or insulation resistance, carefully considering these key differences is vital to selecting the connector that aligns seamlessly with project requirements.
