Substitute Part Grouping Explanation

Substitute parts for the 5221185-8 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Connector style (BNC)
• Connector type (Plug, Male Pin)
• Impedance (75 Ohms)
• Contact and shield termination method (Crimp)
• Mounting type (Free Hanging/In-Line)
• Cable group compatibility (RG-179, 179A, 179B, 187, 187A)
• Fastening type (Bayonet Lock)
• Frequency rating (2 GHz minimum)
• Operating temperature range (-55°C to 85°C minimum)
• Voltage rating (500 V minimum)
• Mating cycle rating (500 minimum)

Parts meeting all critical parameters are classified as equivalent or substitute components. Variations in product status, compliance certifications, or packaging do not affect functional substitution eligibility when all electrical and mechanical parameters align.

The 413589-8 is the recommended long-term substitute for the obsolete 5221185-8. This part maintains all critical electrical and mechanical parameters and is classified as active product status, ensuring continued availability and supply chain stability. The component is RoHS non-compliant. Current inventory availability is 844 pieces. Selection of this part is appropriate for new designs and ongoing production where long-term component availability is required.

Frequently Asked Questions (FAQ)

Q: Can 221185-8 and 413589-8 be used interchangeably with 5221185-8?

A: Both 221185-8 and 413589-8 meet all critical electrical and mechanical parameters specified for the 5221185-8, including impedance, connector type, termination method, cable compatibility, frequency rating, and operating specifications. Functional substitution is supported based on parameter matching.

Q: What is the difference between the main part and the substitute parts?

A: The primary differences are product status and RoHS compliance. The 5221185-8 is obsolete and RoHS compliant. The 221185-8 is obsolete and RoHS non-compliant. The 413589-8 is active product status and RoHS non-compliant. All three parts are electrically and mechanically equivalent.

Q: Why is 413589-8 recommended for new designs?

A: The 413589-8 carries active product status, indicating ongoing manufacturer support and supply chain availability. This ensures component accessibility for future production runs and system maintenance. The 5221185-8 and 221185-8 are both obsolete, presenting potential supply constraints.

Q: Are there packaging differences between these parts?

A: The 5221185-8 includes 4 pieces per package (1 connector, 1 contact, 1 ferrule, 1 sleeve). The 413589-8 includes 3 pieces per package (1 connector, 1 contact, 1 ferrule). The 221185-8 packaging information is not specified. Verify packaging requirements for your application.

Q: What cable types are compatible with these connectors?

A: All three parts support the same cable groups: RG-179, RG-179A, RG-179B, RG-187, and RG-187A. Cable selection must match the connector's 75-ohm impedance specification.

Q: Are there compliance considerations for part selection?

A: The 5221185-8 is RoHS compliant. Both 221185-8 and 413589-8 are RoHS non-compliant. Applications subject to RoHS directives must use the 5221185-8. For applications without RoHS requirements, all three parts are functionally equivalent.

Q: What is the maximum operating frequency for these connectors?

A: All three parts are rated for a maximum frequency of 2 GHz. Applications requiring higher frequency operation require alternative connector designs.

Q: What are the mating cycle specifications?

A: All three parts are rated for 500 mating cycles. This specification defines the expected number of connect/disconnect operations before performance degradation occurs.
