Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Identical Specifications):

The part 5413879-2 is a direct substitute for 413879-2, differing only in packaging format (tube versus tray). Both maintain identical electrical and mechanical specifications with RoHS compliance. Selection between these parts depends on assembly process requirements and packaging handling procedures.

Tier 2 - TE Connectivity Parametric Equivalents (Active Status):

Parts 227676-1, 5413879-1, and 5415025-1 are parametric equivalents manufactured by TE Connectivity with active product status. These parts satisfy all critical electrical and mechanical requirements. Part 227676-1 and 5413879-1 carry ROHS3 compliance certification, providing enhanced regulatory alignment for applications requiring updated RoHS standards. Part 5415025-1 incorporates dual dielectric materials (PTFE and PMP) with tin body finish, offering alternative material composition while maintaining 4 GHz frequency capability.

Tier 3 - Obsolete Status (Not Recommended for New Designs):

Part 5415025-2 carries obsolete product status and should not be selected for new circuit designs despite available inventory. Obsolete parts present supply chain risk and lack manufacturer support for future production requirements.

Tier 4 - Alternative Manufacturers (Specification Considerations):

Part 031-5540 (Amphenol RF) meets core electrical and mechanical requirements but operates at reduced maximum frequency (1 GHz versus 4 GHz). This part is suitable only for applications with frequency requirements below 1 GHz. Part BNC5-J-P-GN-RA-BH2D (Samtec Inc.) provides extended operating temperature range (-65°C to 125°C) and ROHS3 compliance, suitable for applications requiring enhanced thermal performance. Part VBM211 (Cinch Connectivity Solutions) operates within a narrower temperature range (-40°C to 85°C) and should be evaluated for temperature-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can 5413879-2 be used as a direct replacement for 413879-2?

A: Yes. Part 5413879-2 is electrically and mechanically identical to 413879-2. The only difference is packaging format (tube versus tray). Both parts are manufactured by TE Connectivity with identical specifications and RoHS compliance status.

Q: What is the difference between the TE Connectivity parts (227676-1, 5413879-1, 5415025-1) and the main part 413879-2?

A: All TE Connectivity parts maintain identical electrical specifications (50 ohms, 4 GHz, 500V, -55°C to 85°C). Differences include body finish material (nickel versus tin) and dielectric composition (PMP versus PTFE/PMP combinations). Parts 227676-1 and 5413879-1 carry ROHS3 certification versus standard RoHS compliance on 413879-2.

Q: Why is 5415025-2 listed but not recommended?

A: Part 5415025-2 carries obsolete product status. While inventory is available, obsolete parts lack manufacturer production support and should not be selected for new designs. Active alternatives with identical specifications are available.

Q: Can the Amphenol RF part 031-5540 replace 413879-2 in all applications?

A: No. Part 031-5540 operates at a maximum frequency of 1 GHz, compared to 4 GHz for 413879-2. This part is suitable only for applications with frequency requirements below 1 GHz. Verify application frequency requirements before substitution.

Q: What are the advantages of the Samtec part BNC5-J-P-GN-RA-BH2D?

A: Part BNC5-J-P-GN-RA-BH2D extends the operating temperature range to -65°C to 125°C (versus -55°C to 85°C for 413879-2) and carries ROHS3 compliance. This part is suitable for applications requiring enhanced thermal performance or updated regulatory compliance. The part includes mounting hardware (lockwasher and nut).

Q: Does the Cinch part VBM211 have any temperature limitations?

A: Yes. Part VBM211 operates within a narrower temperature range (-40°C to 85°C) compared to 413879-2 (-55°C to 85°C). This part is not suitable for applications requiring operation below -40°C. Verify application temperature requirements before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry either RoHS Compliant or ROHS3 Compliant certification status. ROHS3 represents updated RoHS standards and may be required for applications with enhanced regulatory requirements.

Q: What packaging formats are available for these BNC connectors?

A: Packaging formats include tray (standard), tube, and bag. Packaging selection depends on assembly process requirements, handling procedures, and inventory management systems. Electrical and mechanical specifications remain identical across all packaging formats.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, provided the application frequency requirement does not exceed the part's maximum frequency rating. All substitute parts maintain identical mechanical mounting characteristics (panel mount, through-hole, right angle, bulkhead nut, bayonet lock) and solder termination compatibility. Verify frequency and temperature requirements for your specific application.
