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 should I verify that EHT-117-01-S-D-RA-03 is compatible with my board footprint and cable assembly?
For EHT-117-01-S-D-RA-03, verify the 2.00 mm pitch, 34-position, 2-row footprint, right-angle through-hole layout, and shrouded 4-wall mating geometry against the PCB land pattern and the mating cable or header assembly. The key checks are board-edge clearance, connector height above the PCB, latch/eject hook access, and whether the mating half is keyed to the same orientation.
Can EHT-117-01-S-D-RA-03 be used in a 3.3 V or 5 V digital interface, or is the current rating the main limit?
EHT-117-01-S-D-RA-03 is a passive connector, so the voltage limit is usually set by the system design rather than the connector body itself. The practical constraints are contact spacing, creepage requirements in the target environment, and whether the 3 A contact rating and gold mating finish match the expected signal or power loading.
Is EHT-117-01-S-D-RA-03 suitable for carrying power as well as signals on the same connector?
EHT-117-01-S-D-RA-03 can be used for mixed signal and low-power distribution when the per-contact current stays within the 3 A rating and the power pins are assigned carefully. For combined power and signal use, confirm return-path placement, pin sequencing, and temperature rise under continuous load, especially if multiple adjacent contacts are carrying current.
What design issues should I check when replacing an existing 2.0 mm right-angle header with EHT-117-01-S-D-RA-03?
When replacing a similar connector with EHT-117-01-S-D-RA-03, compare the exact PCB hole pattern, row spacing, shroud envelope, post length, and cable-side retention method. Small differences in right-angle headers often affect enclosure clearance, mating depth, and how far the cable assembly can tolerate misalignment during insertion.
Can EHT-117-01-S-D-RA-03 be used in industrial equipment exposed to vibration or thermal cycling?
EHT-117-01-S-D-RA-03 is built with an LCP insulator, phosphor bronze contacts, and a -55°C to 125°C operating range, which supports demanding environments. For vibration or thermal cycling, the remaining question is mechanical retention at the mated interface, so the latch lock and eject hook design should be evaluated with the actual cable strain and enclosure constraints.
What should I consider if I need a drop-in alternative to EHT-117-01-S-D-RA-03?
A true drop-in alternative to EHT-117-01-S-D-RA-03 needs the same 34-position, 2.00 mm, dual-row right-angle through-hole geometry, plus compatible keying and latch features. Even parts in the same EHT family can differ in loaded positions, shroud details, or post length, so the replacement must be checked against the PCB and mating assembly, not just the part family name.
How does the keying slot on EHT-117-01-S-D-RA-03 affect assembly and mis-mating risk?
The keying slot on EHT-117-01-S-D-RA-03 helps prevent accidental reverse insertion or incorrect mating with similar 2.00 mm connectors. In production, that reduces assembly ambiguity, but the matching cable connector must carry the corresponding polarization feature; otherwise the connector can still be forced into the wrong interface if the mechanical envelope is permissive.
Is EHT-117-01-S-D-RA-03 appropriate for long-term field deployment?
EHT-117-01-S-D-RA-03 is a reasonable choice for long-term deployment when the application fits its mechanical and electrical limits, including 3 A per contact and the specified temperature range. For extended field use, pay attention to contact fretting, harness strain relief, and whether repeated mating cycles or environmental contamination could affect the gold-plated mating interface.
What PCB layout constraints are most likely to cause problems with EHT-117-01-S-D-RA-03?
The most common layout issues with EHT-117-01-S-D-RA-03 are insufficient keepout behind the right-angle body, hole size mismatch for the through-hole posts, and poor alignment to the mating connector’s insertion path. Because it is a shrouded 4-wall header, surrounding component placement can also interfere with latch operation or cable entry.
If my design previously used another Samtec EHT header, what should I compare before switching to EHT-117-01-S-D-RA-03?
Before switching to EHT-117-01-S-D-RA-03, compare the base product number, exact position count, loaded position count, row configuration, right-angle orientation, and retention style against the existing EHT part. Within the same series, differences in these details can change mating compatibility, board outline clearance, and the effective pinout once the harness is assembled.
