What are the key features of TSM-135-01-S-DH-A-K-TR?
- 70-position dual-row configuration on 0.100" (2.54 mm) pitch for very high I/O density
- Single surface mount (S) tail per contact row for SMT reflow soldering
- Keyed (K) body and alignment post (A) ensuring polarized, error-free connector mating
- Gold-plated contacts providing reliable low-resistance connections over many mating cycles
- Tape-and-reel (TR) packaging for automated high-volume SMT pick-and-place assembly
What is TSM-135-01-S-DH-A-K-TR used for?
The TSM-135-01-S-DH-A-K-TR is used in high-I/O backplane systems, FPGA mezzanine cards, and embedded computing platforms where 70 polarized SMT contacts are required in a single compact connector. The keying and alignment post features are particularly valuable in rack-mounted industrial equipment and automated assembly lines where consistent mating orientation prevents costly PCB damage.

Frequently Asked Questions
With 70 positions in a dual-row layout, how does TSM-135-01-S-DH-A-K-TR support high-I/O FPGA mezzanine designs?
TSM-135-01-S-DH-A-K-TR provides 70 contacts on 0.100" (2.54 mm) pitch in a dual-row SMT footprint, accommodating FPGA GPIO banks, power rails, and ground returns in a single connector. This density is sufficient to interface a full 64-bit data bus plus control signals without requiring multiple adjacent connectors on a mezzanine board.
How does the keying feature on TSM-135-01-S-DH-A-K-TR prevent connector mis-mating in field-serviceable rack equipment?
The -K keying feature creates a physical notch that blocks insertion of non-keyed or incorrectly oriented mating connectors. On a 70-position backplane with multiple connectors of similar appearance, this mechanical safeguard prevents incorrect module seating that could damage signal lines or power contacts during field replacement or maintenance.
What lead time and packaging format should buyers expect when ordering TSM-135-01-S-DH-A-K-TR for production runs?
Samtec's TSM-135 series is available with typical factory lead times of 2–3 weeks for standard orders. The -TR tape-and-reel packaging comes in reel quantities suitable for automated SMT lines, and major electronic distributors carry inventory of popular pin counts, potentially allowing same-week shipment for prototype and small production quantities.
Is TSM-135-01-S-DH-A-K-TR RoHS compliant, and does it support lead-free reflow assembly?
Yes. Samtec's TSM series is designed to meet RoHS directive requirements, and the Pb-free termination finish is compatible with lead-free solder paste and standard reflow profiles peaking at 260°C. Buyers should request the JESD-609 compliance code on purchase documentation to confirm suitability for EU and other global RoHS-regulated markets.
