Parameter Comparison

Engineering Selection Recommendations

TE Connectivity AMP Connectors 5227222-2

This part is a direct manufacturer equivalent with identical electrical and mechanical specifications to the main part number 227222-2. The primary distinction is RoHS3 compliance status. Selection of 5227222-2 is appropriate for applications requiring regulatory compliance with RoHS3 directives. This part maintains the same tin center contact plating and polymethylpentene dielectric material. Inventory availability is significantly higher at 168,300 pieces.

TE Connectivity AMP Connectors 5227222-6

This part is a parametric equivalent with identical electrical and mechanical specifications to the main part number 227222-2. The distinction is center contact plating material, which is gold rather than tin. Gold plating provides enhanced corrosion resistance and is suitable for applications requiring extended connector lifecycle or exposure to corrosive environments. This part is RoHS compliant. Inventory availability is 1,601 pieces.

Amphenol RF 031-5539

This part is a cross-manufacturer substitute from Amphenol RF. All critical parameters match the main part number 227222-2 with the exception of maximum frequency rating, which is 1 GHz rather than 4 GHz. This part is suitable for applications operating at frequencies up to 1 GHz. The dielectric material is polypropylene rather than polymethylpentene, and the body material is zinc die cast. Center contact plating is gold. This part is ROHS3 compliant and REACH affected. Insertion loss is specified at 0.2 dB. Selection of 031-5539 is appropriate only for applications with frequency requirements not exceeding 1 GHz.

Frequently Asked Questions (FAQ)

Q: Can I substitute 227222-2 with 5227222-2?

A: Yes. The 5227222-2 is a direct manufacturer equivalent with identical electrical and mechanical specifications. The primary difference is RoHS3 compliance status. Both parts are functionally interchangeable in all applications. The 5227222-2 is preferred for new designs requiring regulatory compliance.

Q: What is the difference between 5227222-2 and 5227222-6?

A: Both parts are TE Connectivity AMP Connectors with identical electrical and mechanical specifications. The difference is center contact plating material. The 5227222-2 uses tin plating, while the 5227222-6 uses gold plating. Gold plating provides enhanced corrosion resistance. Both are RoHS compliant. Selection depends on environmental exposure and connector lifecycle requirements.

Q: Can I use the Amphenol RF 031-5539 as a substitute for 227222-2?

A: The 031-5539 is a cross-manufacturer substitute suitable only for applications with maximum frequency requirements not exceeding 1 GHz. The main part number 227222-2 is rated to 4 GHz. If your application operates at frequencies above 1 GHz, the 031-5539 is not suitable. For applications limited to 1 GHz or below, the 031-5539 is electrically and mechanically compatible.

Q: Are all substitute parts available in bulk packaging?

A: The main part number 227222-2 includes 3 pieces per connector (1 connector, 1 lockwasher, 1 nut). The substitute parts 5227222-2, 5227222-6, and 031-5539 are available in bulk packaging without included components. Verify packaging requirements for your procurement process.

Q: Do all substitute parts meet RoHS compliance?

A: The main part number 227222-2 is RoHS non-compliant. The substitute parts 5227222-2, 5227222-6, and 031-5539 are all RoHS compliant (ROHS3). If your application requires RoHS compliance, any of the three substitute parts are suitable.

Q: What is the difference in dielectric material between the parts?

A: The main part number 227222-2 and substitute parts 5227222-2 and 5227222-6 use polymethylpentene (PMP) dielectric material. The Amphenol RF 031-5539 uses polypropylene (PP) dielectric material. Both materials are acceptable for 50 Ohm RF applications within the specified operating temperature range of -55°C to 85°C.

Q: Are all parts rated for the same operating temperature?

A: Yes. All parts, including the main part number 227222-2 and all substitute parts, are rated for operating temperatures from -55°C to 85°C and voltage rating of 500 V.

Q: What is the inventory status of each part?

A: Main part 227222-2: 880 pieces. Substitute 5227222-2: 168,300 pieces. Substitute 5227222-6: 1,601 pieces. Substitute 031-5539: 1,027 pieces. All parts are listed as new original in stock.
