Overview

prEN 3545-003 is a CEN draft product standard in the Aerospace series that specifies rectangular electrical connectors with female contacts. It covers connectors with sealed and non‑sealed rears, plastic housing, a locking device and an operating temperature range of −55 °C to 175 °C. These components can be used as receptacles (fixed housings) or plugs (free housings) and are intended for aerospace electrical equipment and systems.

Key topics and technical requirements

  • Scope and use: Applies only to connectors with female contacts in the EN 3545 family; intended for harsh temperature extremes typical in aerospace.
  • Dimensions and mass: Detailed dimensions and tolerances are given (figures and Table 1). Mass limits are specified: non‑sealed housing ≤ 19 g, sealed housing ≤ 21 g.
  • Panel and mounting: Recommended panel cut‑out and mounting details for connectors fitted with the male coding and attachment system; maximum panel thickness 1.6 mm, minimum pitch between connectors 14.2 mm.
  • Contact and delivery conditions: Defines delivery options for assemblies and contacts. Contact standards referenced include EN 3155‑003 and EN 3155‑015; size 8 contacts are delivered separately.
  • Designation and coding: Standardizes part numbering and coding (housing type, contact arrangement, female contact, crimp connection, coding/attachment hardware). Differentiates plating options (cadmium vs zinc‑nickel) with corresponding coding for male/female mounting versions.
  • Marking and traceability: Required marking includes part identity, date of manufacture (year/week) and manufacturer identification.
  • Referenced performance and testing: Technical characteristics and test methods are aligned with EN 3545‑001 (technical specification), EN 3545‑002 (performance and contact arrangements) and EN 2591‑100 (test methods).

Applications and who uses it

  • Aerospace electrical system designers specifying robust rectangular connectors for aircraft and space vehicles.
  • Connector and cable harness manufacturers producing receptacles and plugs to interoperable industry specifications.
  • Procurement and quality engineers ensuring components meet defined mass, dimension, marking and delivery requirements.
  • Maintenance and repair organizations selecting replacement parts compatible with existing EN 3545 connector families.

Related standards

  • EN 3545‑001 (technical specification)
  • EN 3545‑002 (performance and contact arrangements)
  • EN 3155‑003 / EN 3155‑015 (female contacts, crimp)
