Substitute Part Grouping Explanation
Substitution for the 1-227161-0 is determined by strict equivalence across the following critical parameters: BNC connector style, female socket jack type, 50 ohm impedance, panel mount through-hole right-angle configuration, solder termination for both contact and shield, bayonet lock fastening, operating temperature range of -55°C to 85°C, 500 volt rating, and 500 mating cycle capability.
Parametric equivalents maintain all core electrical and mechanical specifications while differing in product status, compliance certifications, center contact plating material, or packaging configuration. Similar parts share the same functional form factor and electrical characteristics but may operate at reduced frequency ranges or incorporate alternative dielectric materials, requiring engineering evaluation for specific applications.

Engineering Selection Recommendations
Parametric Equivalents (Direct Substitutes):
The TE Connectivity parts 227161-1, 227161-7, 5227161-1, 5227161-3, and 5227161-7 are parametric equivalents to the 1-227161-0. All maintain identical electrical specifications (50 ohms, 4 GHz maximum frequency, 500 volt rating, 500 mating cycles) and mechanical configuration (BNC jack, female socket, panel mount through-hole right-angle, solder termination, bayonet lock). These parts are active products with current manufacturing status.
For new designs and systems requiring RoHS compliance, 227161-1, 5227161-1, 5227161-3, and 5227161-7 are compliant alternatives. The 5227161-7 variant offers the highest inventory availability (7850 pcs) and RoHS compliance status.
For applications where RoHS non-compliance is acceptable or legacy system compatibility is required, 227161-7 provides an active equivalent with gold center contact plating matching the original 1-227161-0 specification.
Similar Parts (Functional Alternatives):
The Amphenol RF parts 031-5431-1010 and 031-5538-1010, along with the Molex 0731385013, are similar alternatives that maintain 50 ohm impedance, BNC jack configuration, panel mount through-hole right-angle mounting, and solder termination. These parts operate at reduced maximum frequency (1 GHz for Amphenol RF variants) and incorporate polypropylene dielectric material instead of polymethylpentene. All three are RoHS3 compliant and active products. These alternatives are suitable for applications where 1 GHz frequency operation is sufficient and alternative dielectric materials are acceptable.
Frequently Asked Questions (FAQ)
Q: Can 227161-1 directly replace 1-227161-0 in existing designs?
A: Yes. The 227161-1 is a parametric equivalent maintaining all critical electrical and mechanical specifications: 50 ohm impedance, 4 GHz frequency capability, 500 volt rating, BNC jack female socket configuration, panel mount through-hole right-angle solder termination, and bayonet lock fastening. The primary difference is center contact plating (tin versus gold) and RoHS3 compliance status. Electrical performance is equivalent for standard RF applications.
Q: What is the difference between 227161-7 and 5227161-7?
A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary differences are base product number designation (227161 versus 5227161) and RoHS compliance status. The 227161-7 is RoHS non-compliant, while 5227161-7 is RoHS compliant. The 5227161-7 has significantly higher inventory availability (7850 pcs versus 804 pcs).
Q: Are the Amphenol RF parts 031-5431-1010 and 031-5538-1010 suitable replacements?
A: These Amphenol RF parts are similar alternatives with the same 50 ohm impedance, BNC jack configuration, and panel mount through-hole right-angle mounting. However, they operate at a maximum frequency of 1 GHz compared to 4 GHz for the original part, and use polypropylene dielectric material instead of polymethylpentene. These parts are suitable for applications where 1 GHz frequency operation is sufficient. The 031-5538-1010 is packaged in trays, while 031-5431-1010 is bulk packaged.
Q: What does center contact plating material affect?
A: Center contact plating (gold versus tin) affects contact resistance, corrosion resistance, and long-term reliability characteristics. Gold plating provides superior corrosion resistance and lower contact resistance over extended mating cycles. Tin plating is acceptable for standard applications but may exhibit higher contact resistance in corrosive environments. Both materials are suitable for the specified 500 mating cycle rating.
Q: Is the Molex 0731385013 a direct equivalent?
A: The Molex 0731385013 is a similar alternative maintaining 50 ohm impedance, BNC jack configuration, panel mount through-hole right-angle mounting, and solder termination. It includes the same hardware package (connector, lockwasher, nut) as the original 1-227161-0. However, it uses polypropylene dielectric material and does not specify maximum frequency operation. It is RoHS3 compliant and suitable for applications where alternative dielectric materials are acceptable.
Q: What packaging options are available?
A: TE Connectivity parametric equivalents are available in bulk packaging. The Amphenol RF 031-5538-1010 is supplied in tray packaging, while 031-5431-1010 is bulk packaged. The Molex 0731385013 is bulk packaged. Packaging selection depends on procurement and assembly process requirements.
Q: Which substitute part has the highest inventory availability?
A: The TE Connectivity 5227161-7 has the highest inventory availability at 7850 pcs. This part is a parametric equivalent with RoHS compliance, 4 GHz frequency capability, and gold center contact plating, making it suitable for both legacy system support and new RoHS-compliant designs.
