1. Product Specifications & Technical Parameters

This series of square hole straight insert pin headers supports customized specifications to adapt to diverse PCB design requirements, with standardized core parameters and strict production standards, ensuring consistent product performance and interchangeability.

2. Basic Structural Parameters

3. Environmental & Mechanical Parameters

The operating temperature range of the straight through-hole pin header is -40℃ to +85℃, covering extreme low-temperature and high-temperature working environments of most electronic devices. The storage temperature ranges from -45℃ to +85℃, adapting to long-term transportation and storage conditions. In terms of mechanical performance, the product has excellent PCB retention force, and the through-hole welding structure can firmly lock the pins on the circuit board, effectively resisting vibration, pulling and twisting. The standard plugging life reaches 250–2000 cycles, with no pin deformation, poor contact or insulation damage after repeated plugging. All products comply with RoHS and REACH environmental protection standards, free of harmful substances such as lead, mercury and cadmium, meeting the green production requirements of global electronic products.

Compared with SMT patch pin headers and right-angle pin headers, our straight through-hole pin headers have irreplaceable advantages in structural stability, assembly convenience and environmental adaptability, and are deeply favored by electronic engineers and manufacturers. The core product strengths are summarized as follows:

1. Super Stable Through-Hole Mounting Structure

Adopting professional through-hole direct insertion installation method, the solder tail penetrates the PCB hole and is fixed by wave soldering or manual soldering. This welding and fixing method forms a solid mechanical connection structure, which has far stronger board holding force than SMT mounting. It can effectively resist mechanical vibration, equipment shaking and external pulling force during device operation, avoiding pin falling off, offset and poor contact problems. It is especially suitable for equipment working in vibration environments and products requiring long-term stable operation, greatly improving the overall service life and stability of electronic equipment.

2. Excellent Electrical Transmission Performance

The high-purity conductive pin material ensures low contact resistance and high current-carrying capacity, realizing lossless and stable transmission of power signals and data signals. The standardized pin spacing ensures sufficient creepage distance and clearance distance between pins, effectively preventing crosstalk, short circuit and electric arcing, and improving the anti-interference ability of signal transmission. The optional gold-plating process further optimizes the oxidation resistance of the pins, avoiding poor contact caused by pin oxidation and rust after long-term use, and maintaining consistent electrical performance in high-humidity and corrosive environments.

3. High Temperature Resistance & Safety Reliability

The insulating base is made of high flame-retardant and high temperature resistant engineering plastics, which will not deform, melt or release harmful gases during high-temperature welding and long-term high-load operation. The UL94V-0 flame retardant grade can effectively prevent flame spread and improve the safety level of electronic equipment. The product has passed strict environmental adaptation tests, including high-temperature aging test, low-temperature cold resistance test, humidity resistance test and thermal cycle test, with stable performance and no failure after long-term extreme environment simulation tests.

4. Strong Compatibility & Customization Flexibility

All mainstream specifications are fully compatible with global standard PCB boards and matching female sockets, with zero assembly adaptation cost. The breakable design allows customers to freely cut the pin header into any required pin number according to project needs, which is convenient for prototype debugging and small-batch production. At the same time, we support personalized customization of pitch, pin length, row number, surface plating process, insulator color and special structural requirements, which can fully meet the differentiated design needs of various industrial and civil electronic products.

5. Cost-Effective & Easy to Assemble

The straight through-hole structure is simple and intuitive, with low assembly difficulty, compatible with manual welding and automatic wave soldering processes, which can greatly improve production efficiency and reduce assembly labor costs. The product has a high yield rate in mass production, stable quality consistency, low defective rate, and effectively reduces the after-sales maintenance cost of electronic products. As a universal standard connector, it has a wide range of applications and sufficient stock, supporting fast delivery and bulk wholesale, bringing higher cost performance to customers.

We have sorted out the most common technical and purchasing questions from global customers to help you quickly understand our straight through-hole pin header products and avoid selection and use errors:

Q1: What is the difference between through-hole straight pin header and SMT pin header?

A1: The core difference lies in the mounting method and structural stability. Through-hole straight pin headers adopt plug-in welding fixation, with strong board holding force, vibration resistance and firm connection, suitable for equipment with high stability requirements and vibration working environments. SMT pin headers are patch mounted, which is suitable for thin and light products and high-density circuit boards, but have poor vibration resistance. For industrial equipment, automotive electronics and long-term operating equipment, through-hole straight pin headers are more reliable.

Q2: Can the pin header be cut freely? Will cutting affect the performance?

A2: All our straight through-hole pin headers adopt breakaway design, which can be freely cut into 2P, 3P, 4P and other required pin counts according to actual needs. The cutting position is designed with a reserved break point, which will not damage the structural integrity and electrical performance of the remaining pins after cutting, and has no impact on normal use. It is very suitable for flexible use in prototype debugging and small-batch customized products.

Q3: What plating process should I choose, tin plating or gold plating?

A3: Tin-plated pin headers are cost-effective, suitable for conventional consumer electronics, general industrial equipment, and low-frequency plugging scenarios, meeting daily use needs. Gold-plated products have better oxidation resistance, wear resistance and conductivity, suitable for high-frequency plugging, high-precision signal transmission, high-humidity and corrosive environments, and high-end precision electronic equipment. Customers can choose according to product positioning and usage scenarios.

Q4: Are the products compliant with international environmental protection standards?

A4: All our straight through-hole pin headers fully comply with RoHS and REACH environmental protection regulations, without any harmful substances. The products have passed formal environmental protection testing certification, and can be safely sold and used in European, American and global markets, meeting the green production and export requirements of electronic products.
