TE Connectivity AMP Connectors 329517 BNC Coaxial Adapter Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 329517 is a coaxial connector adapter designed to convert BNC Plug (Male Pin) connections to BNC Jack (Female Socket) connections. This right-angle adapter operates at 50 Ohms impedance and utilizes bayonet locking fasteners for secure mating. The 329517 is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 329517 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Adapter Type: Plug to Jack conversion
• Adapter Series: BNC to BNC (same series conversion)
• Center Gender: Female to Male
• Impedance: 50 Ohms
• Fastening Type: Bayonet Lock
• Mounting Type: Free Hanging (In-Line), Right Angle

Acceptable Variation Parameters:

• Body Material: Zinc Die Cast, Brass, or Zinc Alloy
• Body Finish: Nickel (consistent across all parts)
• Center Contact Material: Beryllium Copper, Brass, or Phosphor Bronze
• Center Contact Plating: Silver or Gold
• Dielectric Material: Polytetrafluoroethylene (PTFE) or Polyethylene (PE)

The substitute parts identified (Amphenol RF 31-209 and TE Connectivity 5-1634526-1) maintain all critical matching parameters while permitting material and plating variations that do not affect functional compatibility in 50 Ohm RF applications.

Engineering Selection Recommendations

Amphenol RF 31-209 (Direct Substitute)

The Amphenol RF 31-209 is the primary substitute for the obsolete TE Connectivity 329517. This part maintains all critical electrical and mechanical parameters required for BNC Plug to Jack conversion at 50 Ohms impedance. The 31-209 holds Active product status, ensuring ongoing availability and supply chain continuity. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications. The 31-209 provides additional operational specifications including maximum frequency rating of 4 GHz, 500 mating cycles, and operating temperature range of -65°C to 165°C. Material composition differences (Brass body with Brass/Phosphor Bronze center contact versus Beryllium Copper) do not affect functional compatibility in 50 Ohm RF applications.

TE Connectivity 5-1634526-1 (Secondary Substitute)

The TE Connectivity 5-1634526-1 serves as a secondary substitute option, maintaining identical adapter functionality and electrical specifications. This part is also classified as obsolete. The 5-1634526-1 differs in center contact plating (Gold versus Silver) and dielectric material (Polyethylene versus PTFE), representing acceptable variations for BNC adapter applications. RoHS compliance status differs (RoHS Compliant versus ROHS3 Compliant), which may affect suitability depending on specific regulatory requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 31-209 directly replace the TE Connectivity 329517 in existing installations?

A: Yes. Both parts maintain identical adapter type, series conversion, center gender configuration, impedance, mounting style, and fastening mechanism. The 31-209 is functionally equivalent for BNC Plug to Jack conversion applications.

Q: What is the significance of the different body materials (Zinc Die Cast, Brass, Zinc Alloy) across these adapters?

A: Body material variations do not affect electrical performance in 50 Ohm RF applications. All materials are compatible with the nickel finish and provide equivalent mechanical durability for bayonet-locked connections.

Q: Does the difference in center contact material (Beryllium Copper versus Brass/Phosphor Bronze) impact performance?

A: No. Both material compositions provide adequate electrical conductivity and contact reliability for 50 Ohm coaxial adapter applications. The choice represents manufacturing variation rather than functional differentiation.

Q: Why does the Amphenol RF 31-209 specify operating temperature and mating cycles while the TE Connectivity parts do not?

A: The 31-209 provides additional operational specifications as part of its active product documentation. The absence of these specifications in the obsolete parts does not indicate inferior performance; rather, it reflects differences in historical product data availability.

Q: Is the difference between PTFE and Polyethylene dielectric material significant for substitution?

A: Both materials are acceptable for BNC adapter dielectric applications. PTFE offers superior high-frequency performance characteristics, while Polyethylene provides adequate performance for standard RF applications. Selection depends on specific frequency and environmental requirements of the end application.

Q: What is the impact of center contact plating differences (Silver versus Gold)?

A: Both silver and gold plating provide adequate corrosion resistance and electrical conductivity for BNC connections. Gold plating offers enhanced corrosion resistance in harsh environments, while silver plating is standard for general RF applications. Selection depends on environmental exposure requirements.

Q: Are all three parts suitable for new design implementations?

A: The Amphenol RF 31-209 is the recommended choice for new designs due to its Active product status and documented operational specifications. The TE Connectivity parts (329517 and 5-1634526-1) are both obsolete and should be used only for replacement in existing systems where the original part number is specified.

Q: Do packaging differences affect compatibility?

A: Packaging format (Bulk versus unspecified) does not affect connector functionality. Packaging selection is determined by procurement and inventory management requirements rather than technical compatibility.
