Key Parameters

Substitute Part Grouping Explanation

Substitution of coaxial connectors in the TNC receptacle category is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitution:

Electrical Parameters (Must Match):

• Connector Style: TNC
• Connector Type: Receptacle, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 11 GHz
• Voltage Rating: 500 V
• Insertion Loss: 0.18 dB

Mechanical Parameters (Must Match):

• Contact Termination: Solder Cup
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Rear Side Nut
• Fastening Type: Threaded

Material & Compliance Parameters (Must Match):

• Center Contact Material: Phosphor Bronze
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Plating: Gold
• Dielectric Material: Polyoxymethylene (POM) Acetal
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Amphenol RF 122332 meets all specified parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 122334 and 122332 are Active product status components with full ROHS3 compliance and REACH compliance documentation. Selection between these equivalent parts is based on inventory availability and procurement lead time requirements.

The 122334 maintains 959 units in current stock inventory. The 122332 maintains 1460 units in current stock inventory, providing greater availability for high-volume procurement scenarios.

Both parts carry identical electrical performance specifications, mechanical interface requirements, and material composition. Both include standard packaging of 4 pieces per connector unit (1 Connector, 1 Lockwasher, 1 Nut, 1 Solder Tag).

Component selection should be based on supply chain requirements and project timeline constraints. No technical performance differentiation exists between these parts.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 122332 be used as a direct replacement for 122334 in existing designs?

A: Yes. The 122332 is a parametric equivalent with identical electrical, mechanical, and material specifications. Direct substitution is supported without design modification.

Q: What are the key parameters that define substitution eligibility for TNC receptacle connectors?

A: Substitution eligibility is determined by matching: connector style (TNC), connector type (receptacle/female socket), impedance (50 ohms), frequency rating (11 GHz maximum), contact termination (solder cup), mounting configuration (panel mount bulkhead), and material composition (brass body with nickel finish, phosphor bronze center contact with gold plating).

Q: Are there differences in packaging between 122334 and 122332?

A: Both parts are supplied in bag packaging. Each unit includes 4 pieces: 1 connector, 1 lockwasher, 1 nut, and 1 solder tag. No packaging differentiation exists.
