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 TMM-137-01-L-S-RA-029 in a mezzanine board-to-board design where the two PCBs are separated by a fixed gap?
TMM-137-01-L-S-RA-029 is a right-angle, through-hole board-to-board header with a 2.00 mm pitch, so it fits mezzanine or parallel-board layouts only when the mating connector and the mechanical stack-up match its geometry. The contact engagement is defined by the mating connector and the board spacing, so the final gap should be checked against the partner receptacle and the required insertion depth, not just the pitch.
Is TMM-137-01-L-S-RA-029 suitable when I need a compact connector for a dense control board?
TMM-137-01-L-S-RA-029 can work in dense layouts because it uses a 2.00 mm pitch and a right-angle footprint, but the unshrouded male-pin format leaves the pins exposed and requires careful keepout planning. It is a better fit when the mating direction and board edge access are already defined, and less suitable when accidental contact or misalignment needs to be mechanically controlled by the connector body.
What should I check before replacing another 2 mm board connector with TMM-137-01-L-S-RA-029?
For TMM-137-01-L-S-RA-029, check the mating height, pin count, row arrangement, orientation, and latch behavior against the existing part. A connector with the same pitch can still differ in contact length, pin exposure, board offset, and retention style, which can change both the mechanical fit and the electrical interface. The 37-position, single-row layout also needs to match the cable or mating header pattern.
Can TMM-137-01-L-S-RA-029 be used as a drop-in replacement for another Samtec TMM series part?
TMM-137-01-L-S-RA-029 may be close to other Samtec TMM headers, but a direct replacement should only be assumed after comparing the exact suffixes, since those encode orientation, contact plating, and packaging-related details. With TMM-137-01-L-S-RA-029, the right-angle through-hole form and 37-position configuration should be verified against the original footprint and the mating connector’s insertion direction.
How do I decide whether TMM-137-01-L-S-RA-029 is appropriate for power and signal routing on the same connector?
TMM-137-01-L-S-RA-029 is rated at 3.2 A per contact, so it can carry modest power rails as well as signals if the current per pin, temperature rise, and trace width are managed correctly. In mixed-use designs, it is common to dedicate multiple pins to power and return paths and keep high-speed or sensitive signals away from noisy load currents.
What are the main reliability considerations for using TMM-137-01-L-S-RA-029 in industrial equipment?
TMM-137-01-L-S-RA-029 is built with phosphor bronze contacts, gold mating finish, and an LCP insulator, which is a combination commonly used for stable contact performance over wide temperature ranges. For industrial use, the practical checks are vibration, mating cycle count, board support, and whether the push-pull mating style provides enough retention for the enclosure and harness conditions.
Is TMM-137-01-L-S-RA-029 a good choice for field replacement or serviceable modules?
TMM-137-01-L-S-RA-029 can work in serviceable assemblies when the mating connector is accessible and the board is mechanically supported during insertion and removal. Because it is unshrouded and right-angle, alignment during service matters; designs that need frequent blind mating usually benefit from additional mechanical guidance or a shrouded alternative.
What should I verify if I plan to use TMM-137-01-L-S-RA-029 with a custom cable assembly instead of a second PCB?
TMM-137-01-L-S-RA-029 can be used in board-to-board or cable-style applications, but the mating connector and cable termination need to match the 2.00 mm pitch and single-row 37-position pattern exactly. The exposed pin style means strain relief, cable exit direction, and insertion force should be checked so the connector does not become the mechanical anchor point for the cable.
Does the gold mating finish on TMM-137-01-L-S-RA-029 affect the choice of mate or the expected lifetime?
TMM-137-01-L-S-RA-029 uses 10.0 µin gold on the mating interface, which supports low contact resistance and better wear behavior than bare or lightly finished contacts in many low-level signal applications. The actual lifetime still depends on mating force, contamination, vibration, and how often the connector is cycled, so the mating partner and environment remain part of the selection.
Can TMM-137-01-L-S-RA-029 handle elevated temperatures in sealed or near-heat-source designs?
TMM-137-01-L-S-RA-029 is specified for -55°C to 125°C, so the connector materials are compatible with many harsh-environment electronics layouts. In a sealed enclosure or near a hot component, the practical limit is usually the local board temperature, solder joint stress, and any derating needed for current carrying at temperature rather than the connector rating alone.
What are the main trade-offs versus a shrouded connector when using TMM-137-01-L-S-RA-029?
TMM-137-01-L-S-RA-029 is unshrouded, which usually saves space and keeps the profile simple, but it gives less mechanical keying and less pin protection than a shrouded header. That makes it suitable when the enclosure, fixture, or mating design already controls alignment, and less suitable when users may connect it manually without guidance.
Is TMM-137-01-L-S-RA-029 a reasonable replacement when the original connector was a 2.54 mm header?
TMM-137-01-L-S-RA-029 is a 2.00 mm pitch connector, so it is not a direct physical replacement for a 2.54 mm header. The smaller pitch changes the PCB footprint, mating hardware, clearances, and creepage distances, so replacing a 2.54 mm part usually requires a full footprint and cable/mate review rather than a simple swap.
