| Contact plating | gold |
| Termination | vertical and right-angle through-hole (THT), surface mount (SMT), press-fit; cable receptacles and plugs with crimp contacts |
| Locking | jackscrews (J-Tek, M2 thread) or latches (L-Tek) |
| Part number | M80-TTTNNFF — same as Harwin Datamate: type, number of contacts, plating; 1:1 replacement by part number |
About the series
The A1-CONNECT M80 series — 2 mm pitch connectors for board-to-board, board-to-cable and board-to-panel connections, offered as a direct replacement for the Harwin Datamate M80 series. Part numbers match one-to-one: product type, number of contacts and plating are read from the same fields of the M80-TTTNNFF part number, so replacement in a BOM comes down to changing the manufacturer.
Three sub-families: signal (up to 96 contacts, two rows), power (4 mm pitch, up to 20 A per contact) and mixed (power and signal contacts in one housing). Versions — vertical and right-angle board-mount (through-hole, surface mount, press-fit) and cable versions with crimp contacts; locking — jackscrews (J-Tek) or latches (L-Tek).
Contacts are gold-plated, operating range −55 to +125 °C, durability over 500 mating cycles. The series is used in industrial automation and robotics, instrumentation, medical equipment, UAV control systems, telecom equipment and avionics — wherever a vibration-resistant, high-density board-to-board interconnect is needed.

Questions and answers
Do A1-CONNECT M80 and Harwin M80 part numbers match?
Yes, one-to-one: Harwin M80-5101242 and A1-CONNECT M80-5101242 are the same version (vertical plug, 6+6 contacts, gold on contacts and tin on tails). The fields of the M80-TTTNNFF part number are read the same way.
What versions are available in the A1-CONNECT M80 series?
Vertical and right-angle board-mount connectors (through-hole, surface mount, press-fit), cable plugs and receptacles with crimp contacts, 4 mm pitch power versions and mixed power-signal versions; locking by jackscrews (J-Tek) or latches (L-Tek).
What are the current rating and temperature range of the M80 series?
Up to 3 A per contact at 25 °C and up to 2.2 A at 85 °C in the standard versions, power contacts — up to 8.5 A, 4 mm pitch power version — up to 20 A; operating temperature −55 to +125 °C.
How do I replace Harwin M80 in a BOM?
Keep the part number unchanged and specify A1-CONNECT as the manufacturer. For critical products, verify the drawing and PCB footprint against the series documentation and request samples if needed.
