Substitute Part Grouping Explanation

Substitute parts for the 6-227079-8 are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalent (Direct Substitution): Parts that maintain identical or superior electrical and mechanical specifications across all critical parameters including connector style, impedance, termination method, mounting configuration, and frequency rating.

Similar Manufacturer Alternative: Parts that share the same connector style and core electrical specifications but may differ in fastening type, frequency capability, or temperature range. These require application-level verification for compatibility.

The following parameters determine substitution eligibility:

Connector Style (BNC required)
Connector Type (Plug, Male Pin required)
Impedance (50 Ohms required)
Contact Termination (Crimp required)
Shield Termination (Crimp required)
Mounting Type (Free Hanging/In-Line required)
Voltage Rating (500 V minimum)

Engineering Selection Recommendations

Parametric Equivalent - Recommended Primary Substitute:

Part number 27-9119 (Cinch Connectivity Solutions AIM-Cambridge) is the parametric equivalent for the 6-227079-8. This BNC connector plug maintains identical electrical specifications including 50 Ohm impedance, crimp termination for both center contact and shield, bayonet lock fastening, 4 GHz maximum frequency, and 500 V voltage rating. Operating temperature range matches the original part (-55°C ~ 85°C). The part is currently active in production and RoHS compliant, addressing the obsolescence and compliance limitations of the original component. Cable group compatibility with Belden 89907 is maintained.

Active Alternative - Secondary Substitute:

Part number 112514 (Amphenol RF) provides an active alternative with enhanced specifications. This BNC connector plug meets all core electrical requirements with 50 Ohm impedance, 500 V voltage rating, and 4 GHz frequency capability. The contact termination supports both crimp and solder options, providing additional assembly flexibility. Operating temperature range extends to -65°C ~ 165°C, exceeding the original specification. The part is ROHS3 compliant and REACH affected. Insertion loss matches the original at 0.2 dB. Compatibility extends to cable groups RG-55, 142, 223, and 400, providing broader cable options than the original.

Not Recommended - Different Connector Style:

Part number 122114 (Amphenol RF) is a TNC connector plug, not a BNC connector. Although it shares 50 Ohm impedance, crimp termination, and 500 V voltage rating, the different fastening type (threaded versus bayonet lock) and connector style make it incompatible with existing BNC mating interfaces. This part is suitable only for applications requiring TNC connectors.

Frequently Asked Questions (FAQ)

Q: Can the 27-9119 directly replace the 6-227079-8 in existing assemblies?

A: Yes. The 27-9119 maintains identical connector style (BNC), fastening type (bayonet lock), impedance (50 Ohms), termination method (crimp), and frequency rating (4 GHz). Operating temperature range and voltage rating are equivalent. The part is compatible with Belden 89907 cable, matching the original specification.

Q: What is the primary advantage of using 112514 over 27-9119?

A: The 112514 offers extended operating temperature range (-65°C ~ 165°C versus -55°C ~ 85°C) and dual termination capability (crimp or solder). Both parts are electrically equivalent at 50 Ohms with 4 GHz frequency rating and 500 V voltage rating. The 112514 supports additional cable groups (RG-55, 142, 223, 400) beyond the original Belden 89907 specification.

Q: Why is the 122114 not suitable as a substitute?

A: The 122114 is a TNC connector plug with threaded fastening, not a BNC connector with bayonet lock fastening. Although both are 50 Ohm connectors, the different connector style and fastening mechanism prevent mating with existing BNC receptacles. The 122114 is designed for applications requiring TNC interfaces.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 6-227079-8 original part has unspecified packaging. The 27-9119 is supplied in bulk packaging. The 112514 is supplied in bag packaging. The 122114 has unspecified packaging. Packaging differences do not affect electrical or mechanical compatibility; they relate only to order quantity and handling.

Q: What compliance improvements do the substitute parts provide?

A: The original 6-227079-8 is RoHS non-compliant. Both 27-9119 and 112514 are RoHS compliant (27-9119 is RoHS compliant; 112514 is ROHS3 compliant). The 112514 is additionally REACH affected, indicating compliance with REACH regulations. These improvements address regulatory requirements for new designs and procurement.

Q: Do the substitute parts maintain the same insertion loss specification?

A: The 27-9119 insertion loss is not specified in available data. The 112514 maintains the original 0.2 dB insertion loss specification. The 122114 provides superior insertion loss at 0.18 dB, though it is not a BNC equivalent.

Q: What is the inventory status of substitute parts?

A: The 27-9119 has 739 pieces in stock. The 112514 has 1929 pieces in stock. The 122114 has 826 pieces in stock. All substitute parts are currently available for procurement.
