Engineering Selection Recommendations
For Direct Manufacturer Substitution (TE Connectivity AMP Connectors):
The part 5221185-3 is the primary recommended substitute for the obsolete 221185-3. Both components share identical electrical specifications, impedance, termination methods, and frequency ratings. The 5221185-3 is currently in active production status with RoHS3 compliance, addressing regulatory requirements that the original part does not meet. The component is supplied in bulk packaging with identical connector geometry and mating characteristics.
The part 413589-3 provides an alternative TE Connectivity substitute with active product status. This component maintains all critical electrical parameters and operates within the same temperature and voltage specifications. The zinc body material and polyethylene dielectric are functionally equivalent to the original design.
The part 1-413589-6 offers another TE Connectivity option with active status. This component features a brass body and polymethylpentene dielectric, maintaining electrical equivalence while offering different material composition. RoHS compliance status differs from the original part.
The part 5413589-3 is not recommended for new designs despite RoHS compliance, as it carries obsolete product status classification.
For Cross-Manufacturer Substitution (Amphenol RF):
The part 112955-11 is suitable for applications requiring enhanced frequency performance and extended operating temperature range. This component operates at 6 GHz maximum frequency compared to the original 2 GHz specification, with operating temperature range of -65°C to 165°C. The PTFE dielectric and RoHS3 compliance provide regulatory alignment. This part is compatible with RG-122, 180, 180A, 180B, 195 cable groups and Belden 1855, 1865A cables.
The part 031-80108 provides 4 GHz frequency capability with extended temperature range (-65°C to 165°C) and PTFE dielectric material. This component is compatible with Belden 8281 cable group and carries RoHS3 compliance with REACH affected status.
The part 112133 operates at 4 GHz frequency with POM acetal dielectric material. This component is compatible with RG-179, 179A, 179B, 187, 187A cable groups and Belden 9221, M17/94-RG179 cables. RoHS3 compliance and REACH affected status apply.
Compliance Considerations:
For applications requiring RoHS3 compliance, the following parts are suitable: 5221185-3, 031-80108, 112133, and 112955-11. The original 221185-3 and 1-413589-6 are RoHS non-compliant. The 413589-3 carries "Not applicable" RoHS status.
For applications requiring REACH compliance, Amphenol RF parts (031-80108, 112133, 112955-11) carry REACH affected status. TE Connectivity parts show vendor undefined REACH status.
Frequently Asked Questions (FAQ)
Q: Can the 5221185-3 be used as a direct replacement for the 221185-3?
A: Yes. The 5221185-3 maintains identical electrical specifications, impedance, termination methods, frequency rating, voltage rating, and mating cycle count. Both components are BNC plug connectors with 75 ohm impedance, crimp termination, and bayonet lock fastening. The primary differences are product status (active versus obsolete) and RoHS compliance (RoHS3 versus non-compliant). The 5221185-3 is supplied in bulk packaging with included connector, contact, and ferrule components.
Q: What are the key differences between TE Connectivity and Amphenol RF substitutes?
A: TE Connectivity substitutes (5221185-3, 413589-3, 1-413589-6, 5413589-3) maintain the original 2 GHz frequency specification and -55°C to 85°C operating temperature range. Amphenol RF substitutes (031-80108, 112133, 112955-11) offer higher frequency ratings (4 GHz to 6 GHz) and extended operating temperature ranges (-65°C to 165°C). Amphenol RF parts feature PTFE or POM acetal dielectrics compared to polyethylene or polymethylpentene in TE Connectivity parts. Cable group compatibility differs between manufacturers.
Q: Are the Amphenol RF parts backward compatible with systems designed for the 221185-3?
A: Amphenol RF parts are electrically compatible for 75 ohm coaxial applications within the original 2 GHz frequency specification. However, the higher frequency ratings and extended temperature ranges represent performance enhancements rather than direct equivalents. The insertion loss specification differs (0.2 dB for Amphenol RF versus 0.15 dB for the original), which may impact signal integrity in sensitive applications. Cable group compatibility must be verified for specific system requirements.
Q: What packaging options are available for substitutes?
A: The 5221185-3 is supplied in bulk packaging. The 112133 is supplied in bag packaging. The 112955-11 is supplied in bulk packaging. The 221185-3, 413589-3, 1-413589-6, and 031-80108 do not specify packaging type in available documentation. Packaging selection should be based on procurement and assembly requirements.
Q: Which substitute is recommended for new product designs?
A: For new designs requiring direct electrical equivalence with modern compliance standards, the 5221185-3 is recommended. This part maintains all original specifications while providing RoHS3 compliance and active product status. For applications requiring enhanced frequency performance or extended temperature operation, the 112955-11 (6 GHz, -65°C to 165°C) or 031-80108 (4 GHz, -65°C to 165°C) are suitable alternatives with RoHS3 compliance.
Q: How do the dielectric materials affect connector performance?
A: The original 221185-3 uses polyethylene (PE) dielectric. Substitute parts employ polyethylene (PE), polymethylpentene (PMP), or polytetrafluoroethylene (PTFE) dielectrics. PTFE dielectrics (used in 031-80108 and 112955-11) provide superior high-frequency performance and extended temperature stability. POM acetal dielectric (used in 112133) offers different electrical characteristics suitable for specific cable group applications. Material selection impacts insertion loss, frequency response, and temperature performance.
Q: What is the significance of the 500 mating cycle rating?
A: All substitute parts maintain the 500 mating cycle specification, indicating the connector is rated for 500 connect-disconnect cycles before performance degradation. This specification is consistent across all listed alternatives and represents the mechanical durability rating for the bayonet lock fastening mechanism.
Q: Are there inventory considerations for substitute selection?
A: Current inventory levels vary across substitutes. The 112955-11 has the highest inventory (2591 pcs), followed by 112133 (1597 pcs) and 5221185-3 (971 pcs). The 221185-3 original part has 940 pcs in stock despite obsolete status. Inventory availability should be considered for procurement planning, particularly for long-term production requirements.
