CT3320 Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The CT3320 is an adapter coaxial connector manufactured by Cal Test Electronics, designed to convert between N Plug (male pin) and SMA Jack (female socket) configurations. This straight-style, free-hanging adapter operates at 50 Ohms impedance with a maximum frequency rating of 12 GHz and supports operating temperatures from -55°C to 155°C.

The CT3320 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring N-to-SMA adapter functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT3320 is determined by strict equivalence across the following critical parameters:

• Adapter Configuration: N Plug (male pin) to SMA Jack (female socket)
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded connections
• Frequency Rating: Maximum 12 GHz or higher
• Operating Temperature Range: -55°C to 155°C or wider
• Compliance: ROHS3 Compliant, REACH Unaffected

The CT3320A meets all substitution criteria as a direct equivalent part manufactured by Cal Test Electronics with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CT3320A is a direct substitute for the obsolete CT3320. Both parts are manufactured by Cal Test Electronics and maintain identical electrical and mechanical specifications across all critical parameters including impedance, frequency rating, operating temperature range, and connector configuration.

The CT3320A carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

The insertion loss differential (0.05 dB versus 0.13 dB) reflects manufacturing variations between the obsolete and active production runs. This difference remains within acceptable tolerances for 50 Ohm RF adapter applications operating at frequencies up to 12 GHz.

Frequently Asked Questions (FAQ)

Q: Can CT3320A be used as a direct replacement for CT3320?

A: Yes. The CT3320A is a direct substitute meeting all electrical and mechanical specifications of the CT3320, including impedance, frequency rating, connector configuration, and operating temperature range.

Q: What is the difference between CT3320 and CT3320A?

A: The primary difference is product status. CT3320 is obsolete; CT3320A is active production. The CT3320A exhibits slightly higher insertion loss (0.13 dB versus 0.05 dB), which remains within acceptable RF adapter performance parameters.

Q: Are there packaging differences between these parts?

A: CT3320 packaging is not specified in available documentation. CT3320A is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What impedance rating applies to both adapters?

A: Both CT3320 and CT3320A operate at 50 Ohms impedance, maintaining compatibility with standard RF systems and test equipment.

Q: What is the maximum operating frequency for these adapters?

A: Both parts support operation up to 12 GHz maximum frequency, suitable for microwave and RF applications within this bandwidth.

Q: Are both parts RoHS compliant?

A: Yes. Both CT3320 and CT3320A are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.
