- Can Samtec HW-08-09-S-Q-200-055 be mounted directly on a standard 2.54 mm through-hole PCB footprint?
- Samtec HW-08-09-S-Q-200-055 uses through-hole solder termination with 16 contacts arranged in two rows. The contact pitch is 2.54 mm, while the row spacing is 5.08 mm, so the PCB footprint must match the 2.54 mm by 5.08 mm contact pattern rather than a typical 2.54 mm dual-row header footprint with 2.54 mm row spacing.
- What mating connector should I use with Samtec HW-08-09-S-Q-200-055 for a 0.200 inch board-to-board stack height?
- Samtec HW-08-09-S-Q-200-055 provides a nominal 0.200 inch (5.080 mm) stack height and has a 0.475 inch (12.065 mm) mating post length. The mating connector should be selected from a compatible Samtec Flex Stack configuration with matching 2.54 mm pitch, 5.08 mm row spacing, contact count, gender, and required engagement depth. The mating connector's insulator and contact geometry should also be checked in the mechanical drawing before layout release.
- Is Samtec HW-08-09-S-Q-200-055 suitable for connecting two parallel PCBs?
- Samtec HW-08-09-S-Q-200-055 can support a compact parallel-board connection when both boards use compatible dual-row footprints and the required 5.080 mm stack height. The design should allow for PCB thickness, solder fillets, connector body clearance, and the mating connector's contact length. A nominal stack-height match alone does not confirm that the two boards will seat fully without excessive contact compression.
- Can I use Samtec HW-08-09-S-Q-200-055 in a right-angle board connection?
- Samtec HW-08-09-S-Q-200-055 is a straight through-hole header spacer connector, so it is intended for mating along the direction of its vertical contacts. It is not a direct replacement for a right-angle header. A right-angle Flex Stack or another connector with the required orientation must be evaluated if the boards need to be parallel or edge-connected in a different geometry.
- How should I choose the PCB hole size for Samtec HW-08-09-S-Q-200-055?
- Samtec HW-08-09-S-Q-200-055 requires plated through-holes, but the supplied product details do not specify the recommended finished hole diameter or contact square-post size. The PCB footprint should therefore be taken from the current Samtec HW-08-09-S-Q-200-055 drawing or CAD file, including finished hole tolerance, pad diameter, and solder-mask clearance. Using a generic 2.54 mm header footprint can create insertion or solder-joint problems even when the pin locations appear correct.
- Can Samtec HW-08-09-S-Q-200-055 carry high current or high-frequency signals?
- The available information identifies Samtec HW-08-09-S-Q-200-055 as a 16-position connector but does not provide current rating, voltage rating, contact resistance, impedance, or insertion-loss data. It should not be approved for high-current power or controlled-impedance high-speed signaling without checking the applicable Samtec electrical specifications. For high-current use, the designer should also evaluate temperature rise, copper width, via capacity, solder-joint capability, and current sharing across contacts.
- Are all 16 positions of Samtec HW-08-09-S-Q-200-055 electrically interchangeable?
- Samtec HW-08-09-S-Q-200-055 provides 16 physical contact positions, but the product details do not establish a contact-current rating, signal-spacing rule, or pin assignment. Individual positions may be assigned to power, ground, or signals as required by the circuit, provided the electrical limits and mating connector pinout are verified. Unused positions can be left open or assigned to ground according to the system's EMI and return-current strategy.
- Can Samtec HW-08-09-S-Q-200-055 be replaced by a standard Samtec TSW-108-07-G-D header?
- Samtec TSW-108-07-G-D may look similar because it is a dual-row 2.54 mm header, but it should not be treated as a drop-in replacement for Samtec HW-08-09-S-Q-200-055. The HW part uses 5.08 mm row spacing and a 0.200 inch stack height, while TSW variants commonly use different row spacing, post lengths, and mating geometry. A replacement review must compare the complete footprint, body dimensions, contact length, stack height, and mating connector.
- Can Samtec HW-08-09-S-Q-200-055 replace a Samtec HTSW series header?
- Samtec HTSW headers can differ from Samtec HW-08-09-S-Q-200-055 in row spacing, post length, insulator dimensions, and intended board-to-board stack configuration. An HTSW part with the same apparent 16-position count may still require a new PCB footprint or change the assembled board spacing. It can be considered during migration only after the specific HTSW part drawing and the existing mating connector have been compared against the HW-08-09-S-Q-200-055 mechanical requirements.
- Is the 0.055 inch tail length of Samtec HW-08-09-S-Q-200-055 suitable for wave or selective soldering?
- Samtec HW-08-09-S-Q-200-055 has a listed solder tail length of 0.055 inch (1.400 mm), but solder-process suitability depends on PCB thickness, finished-hole dimensions, pad geometry, solder pallet design, and the selected wave or selective-solder profile. The assembly process should confirm that the tail extends sufficiently through the board for consistent barrel fill without creating pallet or adjacent-component interference.
- Can Samtec HW-08-09-S-Q-200-055 be installed during a rework operation after the PCB has been populated?
- Samtec HW-08-09-S-Q-200-055 is a through-hole solder-terminated connector, so replacement generally requires access to the solder side and removal of solder from all 16 contacts. Rework should account for plated-through-hole damage, pad lifting, connector alignment, and possible heat transfer into nearby components. A populated-board repair procedure should define extraction and resoldering methods before using Samtec HW-08-09-S-Q-200-055 as a field replacement.
- Is Samtec HW-08-09-S-Q-200-055 appropriate for industrial equipment used for many years?
- Samtec HW-08-09-S-Q-200-055 uses gold-plated mating contacts with a listed 30.0 microinch (0.76 micrometre) finish and is RoHS3 compliant, which supports consideration in long-life equipment. Long-term suitability still depends on the actual mating-cycle count, vibration, shock, temperature, humidity, contamination, and connector retention in the equipment. The system qualification should include contact resistance monitoring, vibration testing, thermal cycling, and inspection of solder joints and mating alignment for the intended environment.
- Does Samtec HW-08-09-S-Q-200-055 require special moisture handling before assembly?
- Samtec HW-08-09-S-Q-200-055 is listed with a moisture sensitivity level of not applicable, so it is not handled like an MSL-rated semiconductor package requiring a floor-life bake schedule. Normal connector storage and assembly controls still apply, including protection from contamination, oxidation of exposed solderable surfaces, mechanical damage, and excessive humidity. The assembly supplier should follow the connector packaging and solder-process guidance available for Samtec HW-08-09-S-Q-200-055.
- Is Samtec HW-08-09-S-Q-200-055 suitable for frequently disconnected equipment?
- Samtec HW-08-09-S-Q-200-055 has gold-plated mating contacts, but the provided data does not state a mating-cycle rating or allowable contact wear. It is more suitable for a defined board-to-board assembly or service connection after the required cycle count and retention force have been verified. Equipment designed for frequent operator disconnection should be evaluated with a connector family specifically rated for that service profile, while confirming compatibility with the HW-08-09-S-Q-200-055 footprint and stack geometry.
