Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

How can I use DW-03-10-T-S-550-002 in a board stack without causing mechanical stress or connector misalignment?
DW-03-10-T-S-550-002 is a 0.550 in (13.970 mm) stack-height, through-hole header spacer, so the mating board spacing and hole placement need to match the stack geometry closely. In practice, the main risk is board-to-board tolerance buildup: if the PCB thickness, hole position, or coplanarity varies too much, the solder joints can see extra stress during assembly or thermal cycling. DW-03-10-T-S-550-002 is usually best when the stack-up is fixed early and both boards can be laid out around the connector geometry.
Can DW-03-10-T-S-550-002 be used for carrying power as well as signals?
DW-03-10-T-S-550-002 can be used for low-current interconnects, but the 3-position, 0.100 in pitch format usually favors signal or light power distribution rather than high-current rails. For mixed power-and-signal use, check the current per contact, temperature rise, and acceptable voltage drop in your actual assembly. DW-03-10-T-S-550-002 is typically a better fit when the electrical load is modest and the design values compact board stacking over heavy power transfer.
What PCB and soldering constraints should I check before choosing DW-03-10-T-S-550-002 for manufacturing?
DW-03-10-T-S-550-002 is a through-hole, solder-terminated part, so the PCB should support plated-through holes, suitable annular rings, and a solder process compatible with the pin geometry. The long tail and stack format also make solder fillet quality and insertion alignment part of the process window. For volume production, DW-03-10-T-S-550-002 should be verified in the actual reflow or wave/hand-solder flow used by the factory rather than assumed from the datasheet description alone.
Is DW-03-10-T-S-550-002 suitable for industrial vibration or repeated mating cycles?
DW-03-10-T-S-550-002 can work in industrial assemblies if the mechanical design prevents connector fretting, flexing, or board resonance from loading the solder joints. The tin-plated mating finish is common, but it is not a substitute for enclosure support or strain relief when vibration is present. DW-03-10-T-S-550-002 is usually more robust when the boards are mechanically restrained and the connector is not the only structure holding the stack together.
What should I consider when replacing another 3-position stack header with DW-03-10-T-S-550-002?
When migrating to DW-03-10-T-S-550-002, compare pitch, stack height, tail length, and pin layout first, because a part that looks similar may still fail mechanically or fail to mate correctly. The 0.550 in stack height and 0.170 in mating post length can change enclosure clearance and board separation enough to affect system fit. DW-03-10-T-S-550-002 is a practical replacement only when the existing design can accept the same hole pattern and stack geometry.
Can DW-03-10-T-S-550-002 replace a different Samtec DW series part number?
DW-03-10-T-S-550-002 may be interchangeable with some Samtec DW family variants, but compatibility depends on stack height, pin count, post length, and tail length rather than the series name alone. Two DW-series parts can differ in mechanical reach or mating position even if the footprint looks close. For DW-03-10-T-S-550-002, confirm the exact suffix and mechanical dimensions before treating it as a drop-in substitute.
Is DW-03-10-T-S-550-002 a good choice for prototypes that may need later migration to production?
DW-03-10-T-S-550-002 is often reasonable for prototypes when the final product is expected to keep the same board spacing and through-hole assembly method. The main migration risk is that a prototype stack height can become embedded in the enclosure or cable routing, making later part changes harder. Using DW-03-10-T-S-550-002 early is most practical when the design team already knows the final interconnect pitch and mechanical envelope.
How does the tin contact finish on DW-03-10-T-S-550-002 affect long-term reliability?
DW-03-10-T-S-550-002 uses tin on the mating posts, which is common for cost-effective connectors and can perform well in controlled environments. Over long service life, contact stability depends on insertion force, fretting exposure, contamination, and whether the connection is static or frequently serviced. DW-03-10-T-S-550-002 is generally better suited to designs with stable mating conditions than to applications that rely on very low and constant contact resistance under harsh contamination.
What clearance issues can arise when stacking boards with DW-03-10-T-S-550-002?
DW-03-10-T-S-550-002 sets a fixed 0.550 in stack height, so nearby components, shields, fasteners, and enclosure walls must clear that separation plus their own tolerances. The 0.830 in overall pin length and 0.110 in tail length can also affect how much room is available on each side of the board. DW-03-10-T-S-550-002 should be checked against the full 3D assembly, not only the PCB footprint.
When would DW-03-10-T-S-550-002 be a poor fit compared with a different interconnect style?
DW-03-10-T-S-550-002 is not a strong choice when the design needs high pin count, frequent blind mating, very high current, or substantial field-service abuse. In those cases, a different connector family may offer better retention, more positions, or more tolerance to repeated handling. DW-03-10-T-S-550-002 is best evaluated as a compact board-stacking solution rather than a universal interconnect.
