Substitute Part Grouping Explanation
Substitution of the 5227716-3 is determined by strict equivalence across the following critical parameters: BNC connector style, female socket jack type, 50 Ohm impedance, solder cup contact termination, panel mount bulkhead configuration with rear side nut, bayonet lock fastening, 4 GHz maximum frequency, 500 V voltage rating, and 500 mating cycles. All substitute parts listed maintain these core electrical and mechanical specifications.
Substitute parts are grouped into two categories:
Parametric Equivalents (TE Connectivity AMP Connectors): Parts 1-1337448-0, 227755-1, 227755-2, 5227169-5, 5227169-7, 5227169-8, and 5227755-1 maintain full functional equivalence with the main part across all critical parameters. These parts differ in secondary attributes such as center contact plating material (gold or tin), dielectric material composition (PTFE or PBT), body material (zinc or brass), and product status (active versus obsolete).
Similar Parts (Alternative Manufacturers): Parts 31-221 and 31-236 from Amphenol RF provide functional equivalence with manufacturer-specific variations in center contact material (beryllium copper versus phosphor bronze), body material (brass versus zinc), and measured insertion loss specifications. Part 31-236 operates at a reduced maximum frequency of 2 GHz compared to the 4 GHz specification of the main part.
Obsolete Cross-Reference: Part 227169-7 shares obsolete product status with the main part and serves as a historical reference for legacy system documentation.

Frequently Asked Questions (FAQ)
Q: Can 5227169-8 directly replace 5227716-3 in existing designs?
A: Yes. Part 5227169-8 maintains all critical electrical and mechanical parameters: BNC connector style, female socket jack type, 50 Ohm impedance, solder cup termination, panel mount bulkhead configuration, 4 GHz maximum frequency, 500 V voltage rating, and 500 mating cycles. The extended operating temperature range (-65°C ~ 165°C versus -55°C ~ 85°C) provides additional performance margin.
Q: What is the difference between gold and tin center contact plating?
A: Center contact plating material affects electrical contact resistance and corrosion resistance characteristics. Gold plating (5227169-8, 5227169-7, 227755-2) provides superior corrosion resistance and lower contact resistance. Tin plating (227755-1, 5227169-5, 5227755-1) offers cost optimization while maintaining functional performance within specified electrical parameters.
Q: Are TE Connectivity and Amphenol RF parts interchangeable?
A: Parts 31-221 and 31-236 from Amphenol RF provide functional equivalence across core parameters but differ in center contact material (beryllium copper versus phosphor bronze), body material (brass versus zinc), and measured insertion loss (0.2 dB specified). Part 31-236 operates at 2 GHz maximum frequency, limiting its use to applications not requiring 4 GHz bandwidth.
Q: What is the significance of PTFE versus PBT dielectric material?
A: Polytetrafluoroethylene (PTFE) dielectric material (5227169-8, 1-1337448-0, 31-221, 31-236) provides superior high-frequency performance and temperature stability. Polybutylene Terephthalate (PBT) dielectric material (227755-1, 227755-2, 5227169-5, 5227169-7, 5227755-1) offers cost optimization while maintaining functional performance within specified electrical parameters.
Q: Why is RoHS compliance status different across substitute parts?
A: RoHS compliance reflects manufacturing process and material composition at the time of production. Parts 5227716-3, 1-1337448-0, 5227169-5, and 5227169-8 carry RoHS Compliant or ROHS3 Compliant certification. Parts 227755-1 and 227755-2 are RoHS non-compliant and require evaluation against specific application regulatory requirements.
Q: What package configurations are available?
A: The main part 5227716-3 is supplied without specified packaging. Substitute parts are available in Bulk packaging (1-1337448-0, 227755-1, 5227169-5, 5227169-7, 5227169-8, 5227755-1, 31-221, 31-236) or unspecified packaging (227755-2, 227169-7). Packaging selection should align with procurement and inventory management requirements.
Q: Can 31-236 be used in applications requiring 4 GHz operation?
A: No. Part 31-236 operates at a maximum frequency of 2 GHz and is not suitable for applications requiring the full 4 GHz bandwidth specification of the original 5227716-3 connector.
Q: What is the inventory status for substitute parts?
A: All substitute parts listed maintain active inventory: 1-1337448-0 (1042 pcs), 227755-1 (4813 pcs), 227755-2 (1085 pcs), 5227169-5 (1830 pcs), 5227169-7 (643 pcs), 5227169-8 (1695 pcs), 5227755-1 (952 pcs), 31-221 (1173 pcs), and 31-236 (1738 pcs). The original 5227716-3 maintains 856 pcs in stock with obsolete product status.
