Frequently Asked Questions (FAQ)

Q: Can I substitute the 7-227079-2 with any of the listed parts?

A: Direct substitution is possible only with parts matching all mandatory parameters: BNC connector style, male pin plug type, 50 ohm impedance, crimp termination for both center contact and shield, free hanging mounting, bayonet lock fastening, 4 GHz maximum frequency, 500 V voltage rating, -55°C to 85°C operating temperature, and 0.2 dB insertion loss. All listed substitute parts meet these requirements.

Q: What is the difference between parts with gold and silver center contact plating?

A: Both gold and silver plating are provided in the substitute list. The main part 7-227079-2 specifies gold plating. Parts 8-5227079-1 and 1-5227079-1 feature silver plating. Both plating options maintain electrical performance within the specified 0.2 dB insertion loss parameter.

Q: Does the dielectric material affect compatibility?

A: The substitute list includes parts with polyethylene (PE), polytetrafluoroethylene (PTFE), and polyoxymethylene (POM) acetal dielectric materials. All maintain the specified 50 ohm impedance and 0.2 dB insertion loss. Material selection does not affect mechanical or electrical compatibility for the specified cable groups.

Q: Are there differences in cable group compatibility?

A: The primary substitute parts support RG-59, 59A, 59B, 62, 62A, and 62B cable groups, matching the main part. The Amphenol RF alternative (112514) supports RG-55, 142, 223, and 400 cable groups. Verify cable group compatibility with your specific application requirements.

Q: What is the significance of the 4-piece versus 3-piece kit configuration?

A: The main part 7-227079-2 includes 4 pieces: 1 connector, 1 contact, 1 ferrule, and 1 spacer. Some substitutes include 3-piece kits (connector, contact, ferrule only). The spacer is an optional component. Verify kit contents match your assembly requirements.

Q: Why is the main part listed as obsolete?

A: The 7-227079-2 is classified as obsolete, indicating discontinued manufacturing. Active substitute parts are available to support ongoing system requirements and new designs. Active alternatives include 225395-2, 227079-7, 5221128-2, 8-227079-1, 1-5227079-1, and 112514.

Q: What is the difference between RoHS compliant and non-compliant parts?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations. RoHS compliant substitutes include 1-5221128-1, 5221128-2, 8-5227079-1, 1-5227079-1, 5227079-7, and 112514. The main part and several substitutes are RoHS non-compliant. Select based on regulatory requirements for your application.

Q: Can I use the Amphenol RF 112514 as a direct substitute?

A: The Amphenol RF 112514 meets all mandatory electrical and mechanical parameters. It differs in cable group support (RG-55, 142, 223, 400 instead of RG-59/62 series), contact termination options (crimp or solder), dielectric material (POM acetal), and operating temperature range (-65°C ~ 165°C). Verify cable compatibility and termination method requirements before selection.

Q: What is the inventory status of substitute parts?

A: Current inventory levels are: 1-5221128-1 (922 pcs), 225395-2 (809 pcs), 227079-7 (910 pcs), 5221128-2 (875 pcs), 8-227079-1 (872 pcs), 8-5227079-1 (987 pcs), 112514 (1929 pcs), 1-5227079-1 (846 pcs), and 5227079-7 (1181 pcs). Inventory levels are subject to change.
