IEC 61169-15:2021

IEC 61169-15:2021 defines the sectional specification for RF coaxial connectors with a 4.13 mm inner diameter of the outer conductor, threaded coupling, and a characteristic impedance of 50 Ω, commonly identified as type SMA. For engineering, procurement, and compliance teams, this technical reference helps establish a shared basis for connector selection, product evaluation, and documented verification activities. IEC 61169-15:2021 is relevant where dimensional compatibility, interface consistency, and conformity assessment are part of the development or acceptance process.

Purpose of IEC 61169-15:2021

The purpose of IEC 61169-15:2021 is to support consistent specification of a widely used RF connector interface for coaxial applications. By defining the sectional requirements associated with type SMA connectors, it provides a structured reference for engineering documentation, technical review, and manufacturing control. The document is typically used to align product design, test planning, and procurement criteria so that connector interfaces can be evaluated against the same technical baseline during compliance workflows and quality assurance activities.

Compliance applications of IEC 61169-15:2021

IEC 61169-15:2021 is commonly used in compliance preparation for RF assemblies, interconnect components, laboratory test setups, and equipment that depends on threaded 50 Ω coaxial interfaces. It may support technical assessment of connectors used in communications, instrumentation, measurement systems, and other electronics environments where reliable mating and repeatable performance are important. Organizations often use it as a compliance reference during supplier qualification, incoming inspection, product validation, and conformity assessment documentation.

Benefits of IEC 61169-15:2021

Using IEC 61169-15:2021 can improve operational consistency by giving engineering and procurement teams a clear technical basis for specifying and checking SMA-type RF connectors. It helps reduce interface mismatches, supports testing consistency, and can streamline verification activities across design, production, and acceptance workflows. The document is also useful for risk management because it strengthens traceability in product evaluation and helps align technical validation with documented requirements during regulatory preparation and quality reviews.
