- Confirm connector and electrical specifications: Review pinout, impedance, shielding, resistance, signal integrity, voltage, current, connector mating cycles, and compatibility with the target equipment.
- Evaluate materials and construction: Check conductor type, insulation, jacket material, shielding, strain relief, overmolding, bend radius, color coding, labeling, and any patient-contact or biocompatibility requirements.
- Review quality and documentation: Ask for drawings, bills of materials, inspection plans, test records, material declarations, certificates, traceability information, and change-notification procedures.
- Assess manufacturing fit: Compare engineering support, prototyping, minimum order quantities, production capacity, lead times, tooling ownership, packaging, and continuity of supply.
- Request samples and testing: Approve production only after evaluating representative samples under the electrical, mechanical, cleaning, sterilization, and environmental conditions expected in service.
- Consider total cost: Unit price is only one factor. Tooling, validation, rejected parts, field replacement, documentation, logistics, and supplier changes can materially affect the lifetime cost.
