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

Can I use HTSS-102-02-G-D-LL as a board-to-board connector if I need a keyed 2x2 interface on a 2.54 mm pitch?
Yes. HTSS-102-02-G-D-LL is a 4-position, 2-row shrouded header on 2.54 mm pitch, so it suits compact board-to-board interconnects where a keyed mate is helpful. The keying slot helps prevent incorrect orientation during assembly, but the mating connector must be selected to match the same pitch, row spacing, and shroud geometry.
Is HTSS-102-02-G-D-LL appropriate for replacing a generic 2.54 mm pin header on an existing PCB?
HTSS-102-02-G-D-LL can replace a standard 2.54 mm header only if the board footprint supports a 2-row, 4-position shrouded through-hole part with the same mechanical envelope and lead pattern. The shroud, push-pull latch behavior, and pin length may affect nearby components, enclosure clearance, and mating connector compatibility, so the existing layout should be checked against the mechanical drawing before substitution.
What should I verify before using HTSS-102-02-G-D-LL in a design with vibration or repeated mating cycles?
For HTSS-102-02-G-D-LL, the main checks are retention, strain on the PCB, and mating alignment. The push-pull style helps with controlled disengagement, but the connector is still through-hole soldered, so board support and pad quality matter under vibration. Repeated mating also makes the gold contact finish and alignment features relevant, especially if the connector will be serviced often.
Can HTSS-102-02-G-D-LL be used in industrial equipment that runs across a wide temperature range?
HTSS-102-02-G-D-LL is specified for -55°C to 125°C, which fits many industrial environments. In practice, you still need to confirm the full assembly, not just the connector, because solder joints, PCB material, and any mated cable or daughtercard components may have narrower operating limits than the connector itself.
What are the design trade-offs of choosing HTSS-102-02-G-D-LL instead of an unshrouded header?
HTSS-102-02-G-D-LL gives better polarization and mechanical guidance because it is shrouded and keyed. The trade-off is extra height and larger keepout requirements compared with an open-pin header. That matters when the mating board has tall components nearby or when stack height and enclosure clearance are tight.
How do I know whether HTSS-102-02-G-D-LL is suitable for power connections, not just low-level signals?
HTSS-102-02-G-D-LL does not list a current rating in the provided data, so a power application should be treated cautiously unless the operating current, temperature rise, and contact count are validated for your specific use case. For higher-current rails, many engineers prefer a connector family with an explicit current specification rather than inferring capacity from pin size alone.
If I need a drop-in alternative to HTSS-102-02-G-D-LL, what dimensions should I compare first?
For an alternative to HTSS-102-02-G-D-LL, compare pitch, row spacing, number of positions, shrouded versus unshrouded style, mounting method, contact length, and overall height first. Even connectors that look similar may differ in mating depth, keying, and post length, which can change both mechanical fit and the final assembly stack.
Does HTSS-102-02-G-D-LL need a special mating connector, or will any 2.54 mm female header work?
HTSS-102-02-G-D-LL should be paired with a mating part that matches its shrouded 2-row geometry and mating depth, not just any generic 2.54 mm receptacle. A plain female header may fit the pitch but still fail to mate properly if the shroud, keying slot, or pin length does not align with the intended partner.
What assembly or PCB layout issues can come up when placing HTSS-102-02-G-D-LL near tall components or board edges?
HTSS-102-02-G-D-LL has a defined insulation height and protruding post length, so nearby components, enclosure walls, and board-edge clearances need to be checked early. The shroud can also interfere with angled access tools or adjacent connectors, and the through-hole tails require enough underside clearance for soldering and inspection.
Is HTSS-102-02-G-D-LL a good choice for long-term storage, contract manufacturing, or high-reliability assembly flows?
HTSS-102-02-G-D-LL is RoHS3 compliant and has MSL 1 classification, which simplifies handling because it does not impose moisture-bake constraints in normal storage. For long-term reliability, the practical focus is on solder quality, gold contact integrity, and whether the mating cycle profile matches the application, since those factors usually dominate field performance for this kind of connector.
