Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5222506-1

The 5222506-1 is a parametric equivalent to the 3-227000-4 across all critical electrical and mechanical specifications. Both components are classified as obsolete products. The substitute part provides identical performance characteristics for TNC 50 ohm RF applications with RG-58 cable compatibility.

Compliance Consideration:

The 5222506-1 carries RoHS compliant certification, whereas the 3-227000-4 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 5222506-1 is the appropriate selection. For legacy systems or applications without RoHS mandates, either part satisfies functional requirements.

Dielectric Material Difference:

The 3-227000-4 utilizes polyethylene (PE) dielectric material, while the 5222506-1 uses polypropylene (PP). Both materials are standard in RF coaxial connector applications and maintain equivalent electrical performance at the specified frequency range (7 GHz maximum) and operating temperature range (-55°C ~ 85°C).

Inventory Availability:

The 5222506-1 is available with 924 pieces in stock, compared to 702 pieces for the 3-227000-4, providing improved supply continuity for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can the 5222506-1 directly replace the 3-227000-4 in existing assemblies?

A: Yes. The 5222506-1 is a parametric equivalent across all critical electrical and mechanical parameters. Both components are TNC male plug connectors with 50 ohm impedance, crimp termination, and compatibility with RG-58 series cables. Physical dimensions, mating interfaces, and performance characteristics are equivalent.

Q: What is the significance of the dielectric material difference (PE vs. PP)?

A: Both polyethylene and polypropylene are standard dielectric materials in RF coaxial connectors. At the maximum frequency rating of 7 GHz and within the operating temperature range of -55°C to 85°C, both materials provide equivalent electrical performance. Material selection does not affect substitution compatibility.

Q: Why is the 5222506-1 RoHS compliant while the 3-227000-4 is not?

A: RoHS compliance status reflects manufacturing process and material composition standards at the time of production. The 5222506-1 was manufactured to meet RoHS directives, eliminating restricted substances. For applications requiring RoHS compliance, the 5222506-1 is the appropriate selection.

Q: Are there any performance differences between these connectors?

A: No. Both connectors meet identical electrical specifications: 50 ohm impedance, 7 GHz maximum frequency, 500 V voltage rating, and 500 mating cycles. Operating temperature range, contact materials, and plating specifications are identical.

Q: What cable types are compatible with both connectors?

A: Both the 3-227000-4 and 5222506-1 are compatible with RG-58, RG-58A, RG-58B, and RG-58C coaxial cables. Crimp termination is required for both connectors.

Q: Is the package configuration identical between the two parts?

A: Yes. Both connectors include 3 pieces per package: 1 connector, 1 contact, and 1 ferrule. Packaging specifications are equivalent.

Q: Can the 5222506-1 be used in high-frequency applications?

A: Yes. The 5222506-1 is rated for frequencies up to 7 GHz, making it suitable for RF and microwave applications within this frequency range. Performance is equivalent to the 3-227000-4 across the entire frequency specification.
