Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 228979-6 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Identical Electrical & Mechanical Parameters): Parts that maintain the same connector type (Jack, Female Socket), impedance (50 Ohms), termination method (Crimp), mounting configuration (Free Hanging In-Line), and fastening type (Bayonet Lock). These parts differ only in packaging format or RoHS compliance status.

Similar Substitutes (Different Electrical or Mechanical Parameters): Parts that share the BNC connector style and bayonet lock fastening but differ in one or more critical parameters such as impedance rating, connector gender (Plug vs. Jack), frequency rating, or cable group compatibility. These parts are listed for reference but require design verification before substitution.

Key Parameters Determining Substitution Eligibility:

Connector Type (Jack vs. Plug gender)
Impedance Rating (50 Ohms vs. 75 Ohms)
Frequency Maximum Rating
Operating Temperature Range
Cable Group Compatibility
RoHS and REACH Compliance Status

Engineering Selection Recommendations

Direct Substitute: TE Connectivity 5228979-6

The 5228979-6 is the primary direct substitute for the 228979-6. Both parts maintain identical electrical and mechanical specifications: 50 Ohms impedance, Jack Female Socket configuration, 4 GHz maximum frequency, and -55°C to 85°C operating temperature range. The critical difference is RoHS compliance status. The 5228979-6 is ROHS3 Compliant, whereas the 228979-6 is RoHS Non-Compliant. For applications subject to RoHS regulations or procurement policies requiring RoHS compliance, the 5228979-6 is the appropriate selection. Both parts are Active in product status with adequate inventory availability (1235 pcs vs. 843 pcs).

Similar Substitutes with Impedance Variation:

The 5-1634514-1 (TE Connectivity) and 31-71008-RFX (Amphenol RF) are 75 Ohm variants. These parts are not direct substitutes due to impedance mismatch with the 50 Ohm main part. The 5-1634514-1 is Obsolete and should not be selected for new designs. The 31-71008-RFX is marked Not For New Designs and operates at reduced frequency (2 GHz vs. 4 GHz).

Similar Substitute with Connector Gender Variation:

The 31-321 (Amphenol RF) is a Plug Male Pin connector at 50 Ohms, whereas the main part is a Jack Female Socket. These are complementary connector types used in mated pairs. The 31-321 is Active in product status and offers extended operating temperature range (-65°C to 165°C) compared to the main part. This part is suitable only when a male pin connector is required in the application.

Similar Substitute with Cable Group Variation:

The 000-36800 (Amphenol RF) is a Jack Female Socket at 50 Ohms with identical electrical specifications to the main part. However, it is marked Not For New Designs and supports a different cable group (RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907) compared to the main part (RG-59, 59A, 59B, 62, 62A, 62B). This part is suitable only when cable compatibility with the RG-58 series is required.

Compliance Considerations:

For applications requiring REACH compliance, the 000-36800 and 5-1634514-1 are marked REACH Affected. The 228979-6 and 5228979-6 are marked Vendor Undefined for REACH status. All parts carry ECCN EAR99 classification.

Frequently Asked Questions (FAQ)

Q: Can the 5228979-6 be used as a direct replacement for the 228979-6?

A: Yes. The 5228979-6 is a direct electrical and mechanical substitute. Both parts are BNC Jack Female Socket connectors rated at 50 Ohms with identical frequency, voltage, temperature, and insertion loss specifications. The primary difference is RoHS compliance status. The 5228979-6 is ROHS3 Compliant while the 228979-6 is RoHS Non-Compliant. Selection depends on compliance requirements for your application.

Q: What is the difference between the 228979-6 and the 000-36800?

A: Both are BNC Jack Female Socket connectors at 50 Ohms with 4 GHz frequency rating and 0.2 dB insertion loss. The main differences are: (1) Manufacturer (TE Connectivity vs. Amphenol RF), (2) Cable group compatibility (RG-59 series vs. RG-58 series), (3) Product status (Active vs. Not For New Designs), and (4) Body material (Zinc vs. Brass). The 000-36800 is not recommended for new designs.

Q: Why are the 5-1634514-1 and 31-71008-RFX listed as similar substitutes if they have different impedance?

A: These parts are listed for reference purposes only. The 5-1634514-1 is a 75 Ohm Jack connector (Obsolete status), and the 31-71008-RFX is a 75 Ohm Plug connector (Not For New Designs status). Impedance mismatch creates signal reflection and performance degradation. These parts are not suitable substitutes for the 50 Ohm main part unless the application specifically requires 75 Ohm impedance.

Q: What is the difference between packaging formats (Standard, Bulk, Bag)?

A: Packaging format affects procurement and assembly processes but does not alter electrical or mechanical performance. Standard packaging is the default format. Bulk packaging is used for high-volume orders and typically offers cost advantages. Bag packaging is used for smaller quantities. The 5228979-6 (Bulk) and 228979-6 (Standard) are electrically identical; packaging selection depends on order quantity and procurement requirements.

Q: Can the 31-321 (Plug Male Pin) be used instead of the 228979-6 (Jack Female Socket)?

A: No. The 31-321 is a complementary connector type (Plug Male Pin) designed to mate with Jack Female Socket connectors. It cannot replace a Jack Female Socket in the same application. The 31-321 is used when a male pin connector is required in the circuit design. Both parts operate at 50 Ohms and 4 GHz, but they serve different functional roles.

Q: What is the operating temperature range difference between the main part and some substitutes?

A: The 228979-6 operates from -55°C to 85°C. The 000-36800 and 31-321 operate from -65°C to 165°C, providing extended temperature capability. The 31-71008-RFX also operates from -65°C to 165°C. Selection of extended temperature parts is necessary only when the application requires operation outside the -55°C to 85°C range.

Q: Are all listed parts RoHS compliant?

A: No. The 228979-6 is RoHS Non-Compliant. The 5228979-6, 000-36800, 31-321, and 31-71008-RFX are ROHS3 Compliant. The 5-1634514-1 is RoHS Compliant (earlier standard). For applications subject to RoHS regulations, select only ROHS3 Compliant parts.

Q: What does "Not For New Designs" product status mean?

A: Parts marked "Not For New Designs" are still available but are being phased out. These parts should not be selected for new product development. The 000-36800 and 31-71008-RFX carry this status. For new designs, select Active status parts such as the 228979-6, 5228979-6, or 31-321.

Q: What does "Obsolete" product status mean?

A: Parts marked Obsolete are no longer manufactured and should not be selected for any application. The 5-1634514-1 carries Obsolete status and is listed for reference only. Do not use this part for new or existing designs.

Q: How do cable group specifications affect part selection?

A: Cable group specifications define which coaxial cable types are compatible with the connector. The 228979-6 supports RG-59, 59A, 59B, 62, 62A, 62B cables. The 000-36800 supports RG-58, 58A, 58B, 58C, 141, 303, LMR-195, and Belden cables. Selection must match the cable type used in your application. Using incompatible cable types results in impedance mismatch and signal degradation.
