Mounting Type: Through Hole
Contact Termination: Solder
Shield Termination: Solder
Fastening Type: Bayonet Lock
Frequency - Max: 4 GHz

Engineering Selection Recommendations

Tier 1 - Direct Equivalents (Active Status, PTFE Dielectric):

Parts 112404, 112406, 112515, and 112553 are direct parametric equivalents to the Amphenol RF 112483. All are classified as Active and suitable for new designs. These parts share identical electrical specifications, PTFE dielectric material, and ROHS3 compliance. Selection among these parts may be based on inventory availability or procurement source preference without design modification.

Tier 2 - Functional Equivalents with Material Variation:

Part 112538 (Amphenol RF) meets all electrical and mechanical specifications but uses polybutylene terephthalate (PBT) dielectric material instead of PTFE. This part is classified as "Not For New Designs" and should not be selected for new product development. It is retained in this reference for legacy system support only.

Tier 3 - Cross-Manufacturer Equivalents:

Part VB334N (Cinch Connectivity Solutions) and VB335 (Cinch Connectivity Solutions) are functionally equivalent across all critical parameters. VB334N uses brass center contact material and nickel body finish. VB335 uses brass center contact material with tin body finish. Both are Active status and ROHS3 compliant. These parts are suitable for applications where cross-manufacturer sourcing is required.

Tier 4 - Alternative Manufacturer Option:

Part 4578 (Pomona Electronics) meets core electrical specifications and is Active status. However, mating cycle count and insertion loss specifications are not provided. Center contact material is beryllium copper rather than phosphor bronze or brass. This part should be selected only when other options are unavailable and application requirements do not depend on specified mating cycle performance.

Frequently Asked Questions (FAQ)

Q: Can I substitute Amphenol RF 112483 with Amphenol RF 112404?

A: Yes. Part 112404 is a direct parametric equivalent. Both parts share identical electrical specifications, impedance, frequency rating, voltage rating, dielectric material (PTFE), and RoHS compliance. Both are Active status. No design modification is required.

Q: What is the difference between 112483 and 112538?

A: The primary difference is dielectric material. Part 112483 uses PTFE, while 112538 uses PBT. Part 112538 is classified as "Not For New Designs." For new product development, use 112483 or other Active-status alternatives.

Q: Can I use Cinch VB334N or VB335 as substitutes?

A: Yes, both are functionally equivalent. VB334N has nickel body finish; VB335 has tin body finish. Both meet the 50-ohm impedance, 4 GHz frequency, 500 V voltage, and PTFE dielectric requirements. Both are Active status and RoHS compliant. Cross-manufacturer substitution is valid when procurement sources require it.

Q: What is the difference between VB334N and VB335?

A: The difference is body finish. VB334N has nickel finish; VB335 has tin finish. All other electrical and mechanical parameters are identical. Selection depends on finish preference and availability.

Q: Why is Pomona Electronics 4578 listed as Tier 4?

A: Part 4578 does not specify mating cycle count or insertion loss values. While it meets core electrical specifications, the absence of these performance metrics makes it a secondary choice. Use 4578 only when primary alternatives are unavailable.

Q: Are all substitute parts through-hole solder termination?

A: Yes. All listed substitute parts are through-hole mounting with solder termination for both contact and shield. No surface-mount or alternative termination options are included in this reference.

Q: Do all substitute parts have the same packaging?

A: No. Amphenol RF parts (112483, 112404, 112406, 112515, 112538, 112553) are packaged in bags. Pomona Electronics 4578 and Cinch parts (VB334N, VB335) are packaged in bulk. Verify packaging requirements for your procurement process.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts are RoHS compliant. Amphenol RF and Cinch parts are ROHS3 compliant. Pomona Electronics 4578 is ROHS3 compliant. All parts meet environmental compliance requirements for regulated markets.
