This part is currently in active production status, providing long-term availability assurance. The 112132 is ROHS3 Compliant and REACH Affected, meeting current regulatory requirements. The dielectric material differs (polyoxymethylene acetal versus polyethylene), and the supported cable group includes RG-174, 188, 188A, 316, LMR-100, and M17/119-RG174. Current inventory availability is 1609 pieces. This substitute is recommended for new designs and applications requiring active product status and modern regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 1-5227079-9 be used as a direct replacement for the 1-227079-9?

A: Yes. The 1-5227079-9 is electrically and mechanically identical to the 1-227079-9. Both parts share the same BNC connector style, 50-ohm impedance, crimp termination, 4 GHz frequency rating, and all other specified parameters. The primary difference is RoHS compliance status.

Q: What is the difference between the 1-227079-9 and the 112132?

A: Both parts are electrically and mechanically equivalent BNC male plug connectors with 50-ohm impedance, crimp termination, and 4 GHz maximum frequency. The 112132 is manufactured by Amphenol RF rather than TE Connectivity, features polyoxymethylene acetal dielectric material instead of polyethylene, and is currently in active production. The 112132 supports a different cable group specification.

Q: Why is the 1-227079-9 marked as obsolete?

A: The 1-227079-9 is classified as obsolete by the manufacturer. Substitutes such as the 1-5227079-9 or 112132 are recommended for new designs and ongoing system support.

Q: Are there any compatibility concerns when substituting the 112132 for the 1-227079-9?

A: No compatibility concerns exist from an electrical or mechanical standpoint. Both connectors meet identical specifications for impedance, frequency response, voltage rating, and termination methods. The 112132 supports different cable groups; verify cable compatibility with your specific application requirements.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: RoHS compliance is a regulatory requirement in many markets. The 1-227079-9 is RoHS non-compliant, while both the 1-5227079-9 and 112132 are RoHS Compliant or ROHS3 Compliant. If your application or market requires RoHS compliance, select either substitute part.

Q: Which substitute part should be selected for new designs?

A: The 112132 (Amphenol RF) is recommended for new designs due to its active product status, ensuring long-term availability and continued manufacturer support. The 1-5227079-9 is suitable if TE Connectivity product continuity is required.

Q: Are the dielectric materials interchangeable between these parts?

A: The 1-227079-9 and 1-5227079-9 use polyethylene dielectric, while the 112132 uses polyoxymethylene acetal dielectric. Both materials are suitable for the specified electrical parameters and operating conditions. Material selection does not affect substitution compatibility for the stated applications.

Q: What inventory levels are available for each part?

A: Current inventory includes 761 pieces of 1-227079-9, 654 pieces of 1-5227079-9, and 1609 pieces of 112132. Inventory levels are subject to change; verify current availability with your supplier.
