TE Connectivity AMP Connectors 2-330358-2 BNC Plug Coaxial Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-330358-2 is a BNC connector plug with male pin configuration, rated for 50 ohms impedance, and designed for free hanging (in-line) applications using push-on contact termination. This connector is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing procurement and system integration.

The 2-330358-2 operates across a frequency range up to 2.5 GHz and supports mating cycles of 500. Its construction includes brass body with silver finish, gold-plated center contact, and PTFE dielectric material. The connector is compatible with RG-142, 142A, and 142B cable groups and features bayonet lock fastening.

Engineering Selection Recommendations

TE Connectivity AMP Connectors 2-5330358-2:

The 2-5330358-2 is the direct active equivalent to the obsolete 2-330358-2. Both parts share identical electrical and mechanical specifications including 50 ohm impedance, push-on contact termination, 2.5 GHz maximum frequency, and -55°C to 85°C operating temperature range. The 2-5330358-2 holds active product status and is ROHS3 compliant with REACH affected designation, making it suitable for applications requiring current regulatory compliance. This part is the primary recommendation for direct replacement in systems currently using the 2-330358-2.

Amphenol RF 031-326:

The 031-326 provides an alternative BNC plug connector with 50 ohm impedance and free hanging mounting. This part differs in contact termination method (crimp or solder versus push-on), body finish (nickel versus silver), and operating temperature range (-65°C to 165°C versus -55°C to 85°C). The 031-326 supports extended frequency operation to 4 GHz and broader cable group compatibility (RG-55, 142, 223, 400). This part is ROHS3 compliant and REACH affected. Selection of the 031-326 is appropriate for applications requiring crimp or solder termination, extended temperature operation, or higher frequency performance.

Frequently Asked Questions (FAQ)

Q: Can the 2-5330358-2 directly replace the obsolete 2-330358-2?

A: Yes. The 2-5330358-2 maintains identical electrical and mechanical specifications to the 2-330358-2, including 50 ohm impedance, push-on contact termination, 2.5 GHz frequency rating, and -55°C to 85°C operating temperature. The primary difference is product status (active versus obsolete) and regulatory compliance (ROHS3 compliant versus non-compliant).

Q: What is the key difference between the 2-5330358-2 and the 031-326?

A: The primary difference is contact termination method. The 2-5330358-2 uses push-on termination, while the 031-326 uses crimp or solder termination. Additionally, the 031-326 supports higher frequency operation (4 GHz versus 2.5 GHz), extended operating temperature range (-65°C to 165°C versus -55°C to 85°C), and broader cable group compatibility.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both the 2-5330358-2 and 031-326 are ROHS3 compliant and REACH affected. The original 2-330358-2 is RoHS non-compliant with vendor undefined REACH status.

Q: Which substitute part should be selected for applications requiring crimp termination?

A: The Amphenol RF 031-326 is specified for crimp or solder contact termination. The TE Connectivity 2-5330358-2 is specified for push-on termination only.

Q: Can the 031-326 be used in applications currently using the 2-330358-2?

A: The 031-326 is electrically and mechanically compatible as a BNC plug connector with 50 ohm impedance and bayonet lock fastening. However, the contact termination method differs (crimp or solder versus push-on), which may require cable assembly modifications. The extended operating temperature range and higher frequency rating of the 031-326 provide additional performance margin for demanding applications.

Q: What cable groups are compatible with each substitute part?

A: The 2-5330358-2 is compatible with RG-142, 142A, and 142B cable groups. The 031-326 supports RG-55, 142, 223, and 400 cable groups, providing broader cable compatibility.

Q: Are there inventory considerations when selecting a substitute part?

A: Current inventory levels are 730 pcs for the 2-5330358-2 and 948 pcs for the 031-326. The original 2-330358-2 has 790 pcs in stock. Inventory availability should be evaluated against project procurement timelines and volume requirements.
