Substitute Part Grouping Explanation
Substitution of the TE Connectivity 2-5329446-1 is determined by the following critical parameters:
Primary Compatibility Criteria:
- Connector Style: BNC (bayonet lock fastening)
- Connector Type: Plug, Male Pin
- Impedance: 50 Ohms
- Mounting Type: Free Hanging (In-Line)
- Number of Ports: 1
- Voltage Rating: 500 V
- Mating Cycles: 500
Secondary Compatibility Criteria:
- Contact Termination: Push On (original) or Crimp (acceptable substitutes with equivalent electrical performance)
- Shield Termination: Crimp
- Frequency Rating: Minimum 2.5 GHz (original specification)
- Operating Temperature Range: Must accommodate -65°C minimum
- Cable Group Compatibility: RG-161, 179, 187 (original); substitutes must support overlapping cable groups
Substitution Logic: The original part uses push-on contact termination. Equivalent substitutes employ crimp contact termination, which provides equivalent electrical performance and mechanical reliability for the same cable groups. All substitute parts maintain 50-ohm impedance, bayonet lock fastening, and 500-volt rating. Substitutes with frequency ratings of 4 GHz or higher exceed the original 2.5 GHz specification and are fully compatible. Parts with extended operating temperature ranges (-65°C to 165°C) provide enhanced thermal capability beyond the original -65°C to 85°C range.

Frequently Asked Questions (FAQ)
Q: Can I use a crimp-terminated BNC connector as a substitute for the push-on terminated TE Connectivity 2-5329446-1?
A: Yes. Crimp-terminated BNC connectors provide equivalent electrical performance and mechanical reliability for the same cable groups. The contact termination method (push-on versus crimp) does not affect impedance, frequency response, or voltage rating. All substitute parts listed employ crimp termination and are fully compatible with the original cable specifications.
Q: What cable groups are compatible with the substitute parts?
A: The original TE Connectivity 2-5329446-1 supports RG-161, RG-179, and RG-187 cable groups. Substitute parts support overlapping cable groups: 031-242-RFX and 31-242 support RG-179, 179A, 179B, 187, 187A; 031-5999-RFX supports RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, 393; 031-5998-RFX and 112563 support Belden 9913, 9914, LMR-400; 31-315 and 31-315-RFX support RG-174, 188, 188A, 316, LMR-100; 31-320-RFX supports RG-58, 58A, 58B, 58C, 141, 303, LMR-195. Select the substitute part whose cable group matches your application requirements.
Q: Are all substitute parts RoHS compliant?
A: Yes. All substitute parts listed are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions. The original TE Connectivity 2-5329446-1 is RoHS compliant. All substitutes exceed this requirement with ROHS3 certification.
Q: What is the frequency rating difference between the original part and substitutes?
A: The original TE Connectivity 2-5329446-1 has a maximum frequency rating of 2.5 GHz. All substitute parts have a maximum frequency rating of 4 GHz, providing 60% additional frequency margin. This enhanced capability allows use in higher-frequency applications while maintaining full compatibility with the original 2.5 GHz specification.
Q: Do the substitute parts support the full operating temperature range of the original part?
A: Most substitute parts support an extended operating temperature range of -65°C to 165°C, which encompasses the original -65°C to 85°C specification. The exception is 31-320-RFX, which operates from -40°C to 85°C. This part is suitable for applications not requiring the full -65°C lower temperature limit. Verify your application's temperature requirements before selection.
Q: What is the difference between parts marked "Active" and "Not For New Designs"?
A: Parts marked "Active" are in current production and recommended for new designs and ongoing support. The part 031-5998-RFX is marked "Not For New Designs," indicating it is available for legacy system support and repair applications but should not be selected for new product development. For new designs, select from the "Active" status parts listed.
Q: Are there packaging differences between substitute parts?
A: Yes. Substitute parts are available in different packaging configurations: Bulk, Bag, or unspecified. Packaging does not affect electrical or mechanical performance. Select based on your procurement and inventory management requirements. Bulk packaging typically accommodates higher-volume applications, while Bag packaging suits lower-volume needs.
Q: Can I use a TNC connector as a substitute for the BNC connector?
A: No. TNC and BNC connectors are not interchangeable. While both are 50-ohm coaxial connectors, they use different fastening mechanisms (TNC uses threaded fastening; BNC uses bayonet lock) and have different mating interfaces. The substitute parts listed maintain the BNC connector style and bayonet lock fastening of the original part.
Q: What is the insertion loss specification for substitute parts?
A: All substitute parts specify an insertion loss of 0.2 dB. The original TE Connectivity 2-5329446-1 does not provide an insertion loss specification. The 0.2 dB insertion loss of substitute parts represents the signal attenuation through the connector at the specified frequency range and is typical for quality 50-ohm BNC connectors.
Q: How many mating cycles are supported by substitute parts?
A: All substitute parts support 500 mating cycles, matching the original TE Connectivity 2-5329446-1 specification. This represents the number of times the connector can be mated and unmated while maintaining electrical and mechanical performance within specification.
