Substitute Part Grouping Explanation

Substitution of the 227433-1 is determined by strict equivalence across the following critical parameters: connector style (BNC), connector type (Jack, Female Socket), impedance (50 Ohms), mounting configuration (Panel Mount, Through Hole, Right Angle with Bulkhead - Front Side Nut), contact and shield termination method (Solder), fastening type (Bayonet Lock), frequency capability (4 GHz maximum), voltage rating (500 V), mating cycle rating (500), and operating temperature range (-55°C ~ 85°C).

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents (TE Connectivity AMP Connectors): Parts 5227433-1, 227676-2, 5227661-1, 5227676-1, and 5227677-1 maintain identical electrical and mechanical specifications to the main part. These differ primarily in center contact plating material (Tin or Gold), RoHS compliance status, and packaging format. All operate at 4 GHz and support the full operating temperature range.

Cross-Manufacturer Equivalents (Amphenol RF and Molex): Parts 031-5640, 031-6121, and 0731385013 provide functional equivalence with variations in dielectric material, center contact material composition, and frequency rating. Part 031-5640 operates at 1 GHz maximum frequency. Part 031-6121 features an extended operating temperature range (-65°C ~ 165°C) and PTFE dielectric. Part 0731385013 includes integrated board guide and isolation features.

Engineering Selection Recommendations

For RoHS Compliance Requirements: Select 5227433-1, 5227661-1, 5227676-1, 5227677-1, 031-5640, 031-6121, or 0731385013. These parts carry RoHS Compliant or ROHS3 Compliant status. The obsolete 227433-1 and 227676-2 are RoHS non-compliant and unsuitable for new designs subject to RoHS directives.

For REACH Compliance Requirements: Select 5227661-1, 5227677-1, 031-5640, 031-6121, or 0731385013. These parts are REACH Affected or REACH Unaffected. Parts 5227433-1, 5227676-1, and 227676-2 carry Vendor Undefined or REACH Unaffected status.

For Direct TE Connectivity AMP Connectors Replacement: Select 5227433-1 for active production with RoHS compliance and Tin plating, or 5227677-1 for ROHS3 compliance with Gold plating and maximum inventory availability. Both maintain identical electrical specifications to the obsolete 227433-1.

For Extended Operating Temperature Range: Select 031-6121, which operates from -65°C to 165°C compared to the standard -55°C to 85°C range of the main part.

For Frequency-Limited Applications: Part 031-5640 operates at 1 GHz maximum frequency and is suitable for applications not requiring 4 GHz capability.

For Packaging Considerations: Select 5227661-1 for Tube packaging, 5227433-1, 5227676-1, or 5227677-1 for Bulk packaging, or 031-5640 for Tray packaging based on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can 5227433-1 directly replace the obsolete 227433-1?

A: Yes. The 5227433-1 maintains identical electrical and mechanical specifications: 50 Ohm impedance, 4 GHz maximum frequency, 500 V voltage rating, -55°C to 85°C operating temperature, BNC Jack Female Socket configuration, panel mount through-hole right-angle solder termination, and 500 mating cycles. The primary difference is RoHS compliance status and center contact plating material (Tin versus Tin-Lead).

Q: What is the difference between Tin and Gold center contact plating?

A: Both Tin and Gold plating options are provided in the substitute parts. Tin plating (5227433-1, 5227661-1) and Gold plating (227676-2, 5227676-1, 5227677-1, 031-5640, 031-6121, 0731385013) are material variations that do not affect the core electrical specifications of 50 Ohm impedance, 4 GHz frequency capability, or 500 V voltage rating. Selection depends on application-specific corrosion resistance and contact reliability requirements.

Q: Are all substitute parts rated for 4 GHz operation?

A: No. Part 031-5640 is rated for 1 GHz maximum frequency. All other TE Connectivity AMP Connectors substitutes (5227433-1, 227676-2, 5227661-1, 5227676-1, 5227677-1) and Amphenol RF 031-6121 are rated for 4 GHz. Verify frequency requirements before selection.

Q: What is the difference between PMP and PTFE dielectric materials?

A: The main part and most TE Connectivity AMP Connectors substitutes use Polymethylpentene (PMP) dielectric. Amphenol RF 031-6121 uses Polytetrafluoroethylene (PTFE) dielectric and supports an extended operating temperature range of -65°C to 165°C. Amphenol RF 031-5640 and Molex 0731385013 use Polypropylene (PP) dielectric. All three materials maintain 50 Ohm impedance and 500 V voltage rating.

Q: Which substitute part has the highest inventory availability?

A: Part 5227661-1 has 210,158 pieces in stock, significantly exceeding other substitutes. Part 5227677-1 has 2,402 pieces, and 031-5640 has 3,461 pieces. The obsolete 227433-1 has 1,035 pieces remaining.

Q: Are all substitute parts suitable for new product designs?

A: All substitute parts carry Active product status except the main part 227433-1 (Obsolete) and 227676-2 (Active but non-compliant). For new designs, select from 5227433-1, 5227661-1, 5227676-1, 5227677-1, 031-5640, 031-6121, or 0731385013.

Q: What packaging options are available?

A: Bulk packaging is available for 5227433-1, 5227676-1, 5227677-1, 031-6121, and 0731385013. Tube packaging is available for 5227661-1. Tray packaging is available for 031-5640. The main part 227433-1 and 227676-2 do not specify packaging format.

Q: Does the Molex 0731385013 include additional components?

A: Yes. The 0731385013 includes 3 pieces: 1 Connector, 1 Lockwasher, and 1 Nut. Most other parts specify similar inclusions. Verify component kit contents against assembly requirements.

Q: What is the difference between REACH Affected and REACH Unaffected status?

A: REACH Affected status indicates the part contains substances of concern regulated under REACH. REACH Unaffected indicates no such substances. Parts 5227661-1, 5227677-1, 031-5640, and 031-6121 carry REACH Affected status. Parts 5227433-1 and 5227676-1 carry REACH Unaffected status. Compliance requirements depend on end-use application and regional regulations.
