CT3322 Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The CT3322 is a coaxial connector adapter manufactured by Cal Test Electronics, designed to convert between N Jack (female socket) and SMA Jack (female socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 12 GHz, suitable for RF applications requiring series conversion between N and SMA connector types.

The CT3322 is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure continued availability for maintenance, repair, and new system integration where this adapter specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT3322 is determined by the following critical parameters:

• Adapter Configuration: Jack to Jack, Female to Female center gender
• Series Conversion: SMA to N (bidirectional compatibility)
• Impedance: 50 Ohms
• Frequency Rating: 12 GHz maximum
• Insertion Loss: 0.05 dB
• Physical Construction: Straight style, free hanging mounting, threaded fastening
• Material Specifications: Brass body with nickel finish, PTFE dielectric, beryllium copper/brass center contact
• Environmental Compliance: ROHS3 Compliant, REACH Unaffected

The CT3322A qualifies as a direct substitute because it maintains identical electrical performance (50 Ohms, 12 GHz, 0.05 dB insertion loss), identical physical form factor (straight, free hanging), and identical material composition. The primary difference is connector orientation at each end (N to SMA versus SMA to N), which does not affect functional substitution in bidirectional adapter applications.

Parameter Comparison

Engineering Selection Recommendations

The CT3322A is the designated substitute for the obsolete CT3322. Both parts are manufactured by Cal Test Electronics and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The CT3322A carries Active product status, ensuring ongoing availability and manufacturing support. The CT3322, classified as Obsolete, may face supply constraints and discontinued production.

Compliance Alignment: Both parts maintain ROHS3 Compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent component selection in regulated applications.

Inventory Availability: CT3322A inventory (1146 Pcs) exceeds CT3322 inventory (748 Pcs), providing superior supply security for procurement planning.

Selection of CT3322A over CT3322 is supported by active product status, equivalent performance specifications, and superior inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CT3322A directly replace CT3322 in existing applications?

A: Yes. Both adapters maintain identical electrical performance (50 Ohms, 12 GHz, 0.05 dB insertion loss), physical form factor (straight, free hanging), and material composition. The connector orientation difference (N-to-SMA versus SMA-to-N) does not affect functional substitution in bidirectional adapter applications.

Q: What is the primary difference between CT3322 and CT3322A?

A: The connector orientation at each end is reversed. CT3322 converts from N Jack to SMA Jack; CT3322A converts from SMA Jack to N Jack. Both achieve identical series conversion between N and SMA connector types. Product status differs: CT3322 is Obsolete; CT3322A is Active.

Q: Are there packaging differences between these parts?

A: CT3322 packaging is not specified in available documentation. CT3322A is supplied in Bulk packaging. Confirm packaging requirements with procurement specifications before ordering.

Q: Do both parts meet the same environmental operating range?

A: CT3322 operates from -55°C to 155°C. CT3322A operating temperature range is not specified in available documentation. Confirm temperature requirements for your application before selection.

Q: Are both parts suitable for high-frequency RF applications?

A: Yes. Both parts are rated to 12 GHz maximum frequency with 0.05 dB insertion loss, meeting standard RF adapter performance requirements for coaxial connector applications.

Q: What compliance certifications apply to both parts?

A: Both CT3322 and CT3322A are ROHS3 Compliant and REACH Unaffected, satisfying regulatory requirements for electronic component use in regulated markets.
