What are the key features of SEAM-30-03.5-S-06-1-A-K-TR?
- 180-position open-pin-field male header at 0.050" (1.27 mm) pitch for ultra-high-density board stacking and mezzanine card interconnects
- 3.5 mm tail length provides precise PCB-to-PCB stack height control, mating with SEAF socket series in SEARAY high-speed system
- Low 15 milliohm contact resistance with tin-nickel barrier termination ensures reliable, low-loss signal path across the 30-column, 6-row contact array
- Key (K suffix) alignment feature prevents mismate between incompatible SEAM/SEAF pairs in multi-connector backplane designs
- Tape-and-reel (TR) packaging with 2-week-3-day factory lead time enables automated SMT pick-and-place for high-volume production
What is SEAM-30-03.5-S-06-1-A-K-TR used for?
The SEAM-30-03.5-S-06-1-A-K-TR is designed for high-speed mezzanine card, FPGA daughter card, and backplane interconnect applications requiring 180 positions at 0.050" pitch with controlled stack height. It is commonly used in telecommunications line cards, embedded computing modules, and data acquisition systems where the SEARAY connector family provides multi-Gbps signal integrity across dense pin fields. The key retention feature ensures correct mating orientation in multi-connector board assemblies with multiple SEAM/SEAF pairs on the same backplane.

Frequently Asked Questions
How many positions does the SEAM-30-03.5-S-06-1-A-K-TR provide and what is its contact arrangement?
The SEAM-30-03.5-S-06-1-A-K-TR provides 180 positions arranged in 6 rows of 30 contacts each at 0.050" (1.27 mm) pitch. This open-pin-field rectangular contact pattern allows flexible assignment of signal, power, and ground pins across all 180 positions, making it ideal for FPGA mezzanine cards and high-bandwidth data interfaces requiring more than 100 I/O lines.
What stack height does SEAM-30-03.5-S-06-1-A-K-TR provide and which socket does it mate with?
The SEAM-30-03.5-S-06-1-A-K-TR has a 3.5 mm tail length, which sets the PCB-to-PCB stack height when mated with the corresponding SEAF-30-03.5 socket series. SAMTEC SEARAY SEAM headers are available in tail lengths ranging from 3.5 mm to 15 mm, giving system designers multiple stack height options while maintaining the same 180-position, 0.050" pitch footprint on the PCB.
What is the contact resistance of SEAM-30-03.5-S-06-1-A-K-TR and what does this mean for signal integrity?
The SEAM-30-03.5-S-06-1-A-K-TR specifies a maximum contact resistance of 15 milliohms. This low resistance ensures minimal signal loss and voltage drop across the connector interface, supporting reliable multi-Gbps data rates in high-speed backplane and mezzanine card applications. At 180 positions, the low per-pin resistance is critical for maintaining consistent impedance matching across the entire pin field.
What does the 'K' suffix indicate in SEAM-30-03.5-S-06-1-A-K-TR and why is it important in multi-connector boards?
The 'K' suffix designates a key retention feature—a physical polarization tab that prevents the connector from mating with incompatible SEAF sockets or from being inserted in the wrong orientation. In backplane designs with multiple SEAM connectors at the same 0.050" pitch, the key ensures that each daughter card slot can only accept the correct module, preventing costly board damage that could occur if a 180-position card were accidentally inserted with a 10-degree rotation or into an adjacent slot.
