CT3326 SMA Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The CT3326 is a coaxial connector adapter manufactured by Cal Test Electronics, designed to convert between SMA Plug (male pin) and SMA Jack (female socket) configurations at 50 ohms impedance. This adapter operates across RF frequencies up to 18 GHz and is rated for operating temperatures from -65°C to 125°C.

The CT3326 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring SMA coaxial adapter functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CT3326 is determined by the following critical parameters:

• Impedance: 50 ohms (mandatory match)
• Connector Series: SMA to SMA (mandatory match)
• Conversion Direction: The adapter must convert between SMA Plug and SMA Jack configurations
• Frequency Range: Maximum operating frequency of 18 GHz or higher
• Environmental Compliance: ROHS3 compliance and REACH unaffected status

The CT3326A is identified as a direct substitute. While it reverses the conversion direction (SMA Jack to SMA Plug instead of SMA Plug to SMA Jack), it maintains identical impedance, connector series, frequency capability, and compliance certifications. The reversed gender configuration allows the CT3326A to serve equivalent functional roles in applications requiring SMA adapter connectivity.

Parameter Comparison

Engineering Selection Recommendations

The CT3326A is the designated substitute for the obsolete CT3326. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current procurement and deployment.

The primary distinction is product status: CT3326A is active and available, while CT3326 is obsolete. Selection of CT3326A is appropriate for new designs and ongoing production requirements where SMA adapter functionality is needed.

The reversed gender configuration of CT3326A (SMA Jack to SMA Plug) versus CT3326 (SMA Plug to SMA Jack) must be evaluated against specific application requirements to ensure proper mating with existing connector infrastructure.

Frequently Asked Questions (FAQ)

Q: Can CT3326A directly replace CT3326 in all applications?

A: CT3326A provides equivalent SMA adapter functionality but with reversed gender configuration. The CT3326 converts SMA Plug to SMA Jack, while CT3326A converts SMA Jack to SMA Plug. Selection depends on the specific connector genders required in your application.

Q: What impedance is required for SMA coaxial adapters?

A: Both CT3326 and CT3326A operate at 50 ohms impedance, the standard for RF coaxial systems. This impedance must be maintained throughout the signal path.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both CT3326 and CT3326A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

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

A: The CT3326 is rated to 18 GHz maximum frequency. Frequency specifications for CT3326A are not provided in the available data.

Q: Why is CT3326 listed as obsolete?

A: CT3326 is classified as obsolete by the manufacturer. CT3326A, the active substitute, should be used for new designs and ongoing procurement.

Q: What packaging is available for CT3326A?

A: CT3326A is supplied in bulk packaging, differing from the standard packaging of CT3326.
