TE Connectivity AMP Connectors 332225 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 332225 is a BNC twinaxial connector plug designed for free hanging (in-line) crimp termination applications. This coaxial connector features female socket and male pin configuration with non-constant impedance characteristics, compatible with RG-108 and 108A cable groups. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and system integration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 332225 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector style and type (BNC, twinaxial, plug with female socket and male pin)
• Mounting configuration (free hanging, in-line)
• Cable group compatibility (RG-108, 108A)
• Fastening mechanism (bayonet lock)
• Operating temperature range (-55°C ~ 85°C minimum)
• Voltage rating (500 V minimum)

Termination Method Considerations: The main part specifies crimp termination for both contact and shield. Substitute parts may employ alternative termination methods (solder, clamp) provided the connector maintains mechanical and electrical compatibility with the cable group and mating interface.

Impedance Characteristics: The main part features non-constant impedance. Substitute parts with defined impedance specifications (50 Ohms) are acceptable for applications where impedance consistency is required, representing an enhancement to the original specification.

Compliance and Status: Active product status is preferred for long-term availability. RoHS3 compliance is advantageous for regulatory alignment, though not mandatory for substitution eligibility.

Engineering Selection Recommendations

TE Connectivity 5332225-5 (Primary Substitute)

The 5332225-5 represents the direct equivalent from the original manufacturer. This part maintains identical mechanical and electrical specifications to the 332225, including crimp termination for both contact and shield, non-constant impedance, and operating temperature range. The 5332225-5 is active in production status and ROHS3 compliant, providing regulatory alignment and long-term procurement stability. The body finish differs (nickel versus silver), and the dielectric material is polypropylene (PP) rather than PTFE, representing minor material variations that do not affect functional compatibility for standard applications.

Amphenol RF 31-2226 (Alternative Substitute)

The 31-2226 offers enhanced specifications suitable for applications requiring improved performance margins. This part features defined 50-ohm impedance (versus non-constant), extended operating temperature range (-65°C ~ 165°C), and increased mating cycle rating (500 cycles versus 200). The termination method differs, employing solder contact termination and clamp shield termination rather than crimp. This alternative is appropriate for applications where impedance control, thermal performance, or mechanical durability are critical requirements. The 31-2226 is ROHS3 compliant and active in production.

Compliance Considerations

Both substitute parts are ROHS3 compliant, addressing regulatory requirements that the obsolete 332225 does not meet. Selection between substitutes should prioritize application-specific requirements regarding termination method, impedance specification, and thermal operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the 5332225-5 be used as a direct replacement for the 332225?

A: Yes. The 5332225-5 maintains identical connector geometry, termination method (crimp), cable group compatibility (RG-108, 108A), and electrical ratings (500 V, 200 mating cycles). The part is mechanically and electrically interchangeable for applications operating within the -55°C ~ 85°C temperature range.

Q: What is the primary difference between the 5332225-5 and 31-2226?

A: The 5332225-5 maintains the original non-constant impedance specification and crimp termination. The 31-2226 specifies 50-ohm impedance and employs solder contact termination with clamp shield termination. The 31-2226 also provides extended operating temperature range (-65°C ~ 165°C) and higher mating cycle rating (500 cycles).

Q: Can the 31-2226 be used in applications originally designed for the 332225?

A: The 31-2226 is mechanically compatible (BNC twinaxial, bayonet lock, RG-108/108A cable group) and electrically compatible (500 V rating, free hanging mounting). However, the solder termination method requires different assembly procedures than the original crimp specification. Applications requiring crimp termination should use the 5332225-5. Applications where solder termination is acceptable benefit from the 31-2226's enhanced impedance control and thermal performance.

Q: What is the significance of the body finish difference (silver versus nickel)?

A: The body finish affects corrosion resistance and environmental durability. Silver finish (332225) provides lower contact resistance but may oxidize in corrosive environments. Nickel finish (5332225-5, 31-2226) provides superior corrosion resistance and environmental stability. For applications in standard indoor environments, both finishes are functionally equivalent. For harsh or marine environments, nickel finish is preferred.

Q: Are there packaging differences between the substitute parts?

A: The 5332225-5 is supplied in bulk packaging. The 31-2226 is also supplied in bulk packaging. Both parts include connector assembly components (connector, contacts, ferrule, gasket, insulator). The 31-2226 includes additional components (braid clamp, clamp, washers) due to its clamp-based shield termination method.

Q: What is the impedance difference between non-constant and 50 ohms?

A: Non-constant impedance (332225, 5332225-5) indicates impedance variation along the connector length, typical of twinaxial designs without controlled impedance matching. 50-ohm impedance (31-2226) specifies controlled impedance throughout the connector, providing consistent signal transmission characteristics. Applications requiring impedance control for high-frequency or precision signal integrity should use the 31-2226.

Q: Why is the 332225 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by TE Connectivity. The 5332225-5 represents the active replacement in the manufacturer's current product line, offering improved compliance (ROHS3) and production continuity.

Q: Are all three parts ROHS3 compliant?

A: The 332225 is RoHS non-compliant. Both substitute parts (5332225-5 and 31-2226) are ROHS3 compliant, meeting current regulatory requirements for electronic components in regulated markets.
