Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix codes against official Omnetics documentation to confirm exact pin count, orientation, and plating specifications. Ensure compatibility with mating receptacles within the Nano Polarized family. Confirm surface mount footprint dimensions match the target PCB layout before procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when polarized right-angle surface mount headers are required. The 18-position configuration suits dense board layouts. Verify that the 0.025-inch pitch aligns with existing design constraints. Ensure mating connectors support the 1A current rating and operating temperature range.

Headers, Receptacles, Female Sockets Part Context

Part of the Nano Polarized (PZN) series, designed for high-density applications. Utilizes Omnetics' Flex-Pin technology for durability. Commonly used in environments requiring secure, keyed connections to prevent incorrect insertion. Serves as a male header counterpart to female socket receptacles.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other PZN series headers with identical position counts and polarization keys. Verify mechanical footprint compatibility. Cross-reference mating part numbers to ensure electrical and physical alignment.
