Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 112598 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Connector style: BNC
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency maximum: 4 GHz
• Voltage rating: 500 V
• Insertion loss: 0.2 dB
• Mating cycles: 500

Mechanical Equivalence Requirements:

• Contact termination: Crimp
• Shield termination: Crimp
• Mounting type: Free Hanging (In-Line)
• Fastening type: Bayonet Lock
• Number of ports: 1
• Body material: Brass
• Dielectric material: PTFE

Compliance Requirements:

• RoHS3 Compliant
• REACH Affected
• ECCN: EAR99

The TE Connectivity Aerospace, Defense and Marine part 2-331351-1 meets all electrical and mechanical equivalence criteria. Variations in center contact material (Beryllium Copper vs. Phosphor Bronze), body finish (Silver vs. Nickel), and cable group compatibility do not affect functional substitution for 50-ohm BNC jack applications within the specified frequency and voltage parameters.

Engineering Selection Recommendations

Primary Selection: Amphenol RF 112598

The Amphenol RF 112598 is the recommended primary selection. The part maintains active product status with robust inventory availability (1069 units in stock). Full compliance with ROHS3 and REACH regulations is confirmed. The part is suitable for immediate deployment in 50-ohm BNC jack applications requiring crimp termination up to 4 GHz.

Substitute Selection: TE Connectivity 2-331351-1

The TE Connectivity Aerospace, Defense and Marine part 2-331351-1 is functionally equivalent and meets all electrical and mechanical specifications. However, this part is discontinued at DiGi Electronics, which limits long-term availability. The substitute maintains equivalent performance characteristics including 50-ohm impedance, 4 GHz frequency rating, 500 V voltage rating, and 0.2 dB insertion loss. ROHS3 and REACH compliance is confirmed. Inventory availability is lower (1014 units) compared to the primary part.

Cable Compatibility Note:

The Amphenol RF 112598 is specified for Belden 7807A and LMR-200 cable groups. The TE Connectivity 2-331351-1 is specified for RG-58, 58A, 58B, and 58C cable groups. Cable group compatibility must be verified against the specific application requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-331351-1 be used as a direct replacement for the Amphenol RF 112598?

A: Yes, the TE Connectivity 2-331351-1 meets all electrical and mechanical equivalence criteria for 50-ohm BNC jack crimp applications. Both parts operate at identical impedance, frequency, voltage, and insertion loss specifications. However, cable group compatibility differs and must be verified for the specific application.

Q: What is the difference between the center contact materials in these two parts?

A: The Amphenol RF 112598 uses Phosphor Bronze center contact material, while the TE Connectivity 2-331351-1 uses Beryllium Copper. Both materials provide equivalent electrical performance within the specified 4 GHz frequency range and 500 V voltage rating. Material selection does not affect functional substitution for RF signal transmission applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both the Amphenol RF 112598 and TE Connectivity 2-331351-1 are ROHS3 compliant and REACH affected. Both parts meet regulatory requirements for use in restricted substance applications.
