Substitute Part Grouping Explanation
Substitution of the obsolete 227169-7 is determined by strict equivalence across the following critical parameters: connector style (BNC), connector type (jack, female socket), impedance (50 ohms), contact termination (solder cup), shield termination (solder tag), mounting type (panel mount), mounting feature (bulkhead rear side nut), fastening type (bayonet lock), frequency rating (4 GHz maximum), number of ports (1), operating temperature range (-65°C to 165°C), voltage rating (500 V), and mating cycles (500). All substitute parts listed maintain these core electrical and mechanical specifications. Variations in secondary parameters such as body material, center contact plating, dielectric material, and compliance certifications do not affect functional interchangeability within the specified operating envelope.

Engineering Selection Recommendations
Primary Recommendation: 5227169-7
The 5227169-7 is the direct active equivalent of the obsolete 227169-7. Both parts share identical electrical specifications, mechanical configuration, and functional characteristics. The 5227169-7 is ROHS3 compliant and maintains active product status with 643 units in stock. This part is the preferred replacement for direct substitution in new designs and legacy system updates.
Secondary Recommendations: 5227169-8 and 1-1337448-0
The 5227169-8 and 1-1337448-0 are parametric equivalents with full electrical and mechanical compatibility. Both are active products with RoHS compliance. The 5227169-8 offers ROHS3 compliance with 1695 units available. The 1-1337448-0 belongs to the Greenpar series and is RoHS compliant with 1042 units in stock. These parts are suitable for applications where the primary recommendation is unavailable.
Alternative Options: 227755-1, 227755-2, 5227169-5, and 5227755-1
These parts maintain full electrical and mechanical equivalence but differ in compliance status or center contact plating. The 227755-1 and 227755-2 are RoHS non-compliant. The 5227169-5 and 5227755-1 are RoHS compliant alternatives with tin center contact plating (5227169-5, 5227755-1) or gold plating (227755-2). Selection among these options depends on specific compliance requirements and application constraints.
Cross-Manufacturer Option: 31-221-RFX
The Amphenol RF 31-221-RFX provides cross-manufacturer compatibility with ROHS3 compliance and 3693 units in stock. This part maintains all critical electrical and mechanical parameters. Operating temperature range is not specified in available documentation. This option is suitable for applications requiring supplier diversification.
Not Recommended: 5227716-3
The 5227716-3 is obsolete and exhibits a reduced operating temperature range (-55°C to 85°C) compared to the 227169-7 specification (-65°C to 165°C). This part is not suitable for applications requiring the full temperature envelope of the original component.
Frequently Asked Questions (FAQ)
Q: Can the 5227169-7 be used as a direct replacement for the 227169-7?
A: Yes. The 5227169-7 is the active equivalent of the obsolete 227169-7. Both parts share identical BNC connector style, 50 ohm impedance, solder cup termination, panel mount configuration, 4 GHz frequency rating, 500 V voltage rating, and 500 mating cycle specification. The 5227169-7 is ROHS3 compliant and is the recommended replacement.
Q: What is the difference between gold and tin center contact plating?
A: Center contact plating is a secondary parameter that does not affect functional interchangeability within the specified operating envelope. Gold plating (used in 227169-7, 5227169-7, 1-1337448-0, 227755-2, 5227169-8, 31-221-RFX, and 5227716-3) and tin plating (used in 227755-1, 5227169-5, and 5227755-1) both satisfy the electrical requirements of 50 ohm BNC connectors. Selection between these options depends on application-specific requirements and cost considerations.
Q: Are all substitute parts RoHS compliant?
A: No. The 227755-1 and 227755-2 are RoHS non-compliant. The 5227169-7, 5227169-8, 5227755-1, and 31-221-RFX are ROHS3 compliant. The 1-1337448-0 and 5227716-3 are RoHS compliant. For applications requiring RoHS compliance, select from the compliant options listed above.
Q: What is the operating temperature range for the 31-221-RFX?
A: The operating temperature range for the 31-221-RFX is not specified in the provided technical documentation. The 227169-7 and all TE Connectivity AMP substitute parts operate across -65°C to 165°C. The 5227716-3 operates across -55°C to 85°C. For applications requiring the full -65°C to 165°C temperature envelope, use TE Connectivity AMP parts or confirm the 31-221-RFX specification with the manufacturer.
Q: Can the 5227716-3 be used in place of the 227169-7?
A: The 5227716-3 is not recommended. Although both parts are BNC connectors with 50 ohm impedance and solder cup termination, the 5227716-3 has a reduced operating temperature range (-55°C to 85°C) compared to the 227169-7 (-65°C to 165°C). Additionally, the 5227716-3 is obsolete. Use active equivalent parts such as 5227169-7, 5227169-8, or 1-1337448-0 instead.
Q: What packaging options are available?
A: The 227169-7 original part has unspecified packaging. Active substitute parts are available in bulk packaging (5227169-7, 1-1337448-0, 227755-1, 5227169-5, 5227169-8, 5227755-1, and 31-221-RFX) or unspecified packaging (227755-2). Bulk packaging is standard for production quantities. Confirm packaging requirements with your procurement department.
Q: How many mating cycles do these connectors support?
A: All listed parts, including the 227169-7 and all substitute options, support 500 mating cycles. This specification is consistent across all equivalent and substitute components.
Q: What is the voltage rating for these BNC connectors?
A: All listed parts maintain a 500 V voltage rating. This specification is consistent across the 227169-7 and all substitute options.
