CT3393 SMA Coaxial Connector Adapter - Equivalent & Substitute Parts

Part Overview

The CT3393 is a coaxial connector adapter manufactured by Cal Test Electronics, designed to convert SMA Plug (male pin) connections to SMA Jack (female socket) connections with 50-ohm impedance. This adapter operates at frequencies up to 12.4 GHz and is rated for operating temperatures between -65°C and 165°C.

The CT3393 is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure continued availability for system integration, maintenance, and new production builds where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CT3393 is based on strict equivalence across the following critical parameters:

• Adapter Configuration: Plug to Jack conversion with SMA to SMA series matching
• Electrical Characteristics: 50-ohm impedance, threaded fastening, gold-plated contacts
• Mechanical Compatibility: Right-angle mounting, free-hanging in-line configuration
• Material Specification: Brass body with gold finish, PTFE dielectric, beryllium copper and brass center contacts
• Environmental Rating: Operating temperature range of -65°C to 165°C
• Regulatory Compliance: ROHS3 compliance required

The substitute part 132172 (Amphenol RF) meets all these critical parameters. The substitute demonstrates higher frequency capability (18 GHz versus 12.4 GHz) and active product status, making it a direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The CT3393 is obsolete and no longer in active production. The Amphenol RF 132172 is the qualified substitute for new designs and ongoing production requirements.

Selection Basis:

• Both parts maintain ROHS3 compliance and meet the same regulatory framework (ECCN EAR99, HTSUS 8536.69.4010)
• The 132172 carries active product status with higher inventory availability (4908 pcs in stock versus 987 pcs for CT3393)
• Frequency capability of the 132172 (18 GHz) exceeds the CT3393 specification (12.4 GHz), providing margin for system performance
• Identical mechanical, electrical, and material specifications ensure direct form-fit-function compatibility
• Both parts support the same operating temperature range (-65°C to 165°C)

For applications currently using CT3393, transition to 132172 is supported by equivalent electrical and mechanical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 132172 be used as a direct replacement for CT3393?

A: Yes. Both adapters share identical adapter type (plug to jack), series (SMA to SMA), impedance (50 ohms), mounting configuration (right angle, free hanging), and material specifications (brass body with gold finish, PTFE dielectric, gold-plated contacts). Operating temperature ranges are identical (-65°C to 165°C).

Q: What is the difference in frequency capability between these parts?

A: The CT3393 is rated to 12.4 GHz maximum frequency, while the 132172 is rated to 18 GHz. The 132172 supports higher-frequency applications within the SMA connector standard.

Q: Are there packaging differences between CT3393 and 132172?

A: The CT3393 packaging is not specified in available documentation. The 132172 is supplied in bag packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CT3393 and 132172 are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Q: Why is CT3393 listed as obsolete?

A: The CT3393 has been discontinued by Cal Test Electronics. The 132172 from Amphenol RF is the active equivalent product for ongoing supply and new production applications.
