Engineering Selection Recommendations

The Amphenol RF 031-334 is the direct equivalent substitute for the TE Connectivity AMP Connectors 225974-2. Selection of the 031-334 is supported by the following factors:

Product Status: The 225974-2 is classified as obsolete, while the 031-334 maintains active product status, ensuring long-term availability and continued manufacturer support.

Compliance Certifications: The 031-334 is ROHS3 compliant and REACH affected, providing enhanced regulatory compliance compared to the non-compliant status of the 225974-2. This is significant for applications subject to environmental and hazardous substance restrictions.

Electrical and Mechanical Compatibility: Both connectors maintain identical electrical specifications (50 ohms, 4 GHz maximum frequency, 500 V rating, 0.2 dB insertion loss) and mechanical configurations (BNC plug, male pin, right-angle, bayonet lock, free-hanging in-line mounting).

Material Specifications: Both components utilize identical dielectric material (PTFE), body material (brass with nickel finish), and center contact plating (gold). The 031-334 offers optional phosphor bronze center contact material in addition to brass.

Environmental Performance: The 031-334 provides an extended operating temperature range (-65°C ~ 165°C) compared to the 225974-2 (-55°C ~ 85°C), offering broader thermal capability for demanding applications.

Cable Compatibility: The 031-334 supports RG-55, 142, 223, and 400 cable groups, providing broader cable compatibility than the 225974-2 (RG-55, 55A, 55B, 223).

Termination Flexibility: The 031-334 supports both crimp and solder termination methods, while the 225974-2 is limited to crimp termination.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-334 directly replace the TE Connectivity 225974-2 in existing applications?

A: Yes. Both connectors meet identical electrical specifications (50 ohms, 4 GHz, 500 V, 0.2 dB insertion loss) and mechanical requirements (BNC plug, male pin, right-angle, bayonet lock). The 031-334 is electrically and mechanically compatible with the 225974-2.

Q: What is the primary reason for substitution?

A: The TE Connectivity 225974-2 is classified as obsolete. The Amphenol RF 031-334 is an active product with current manufacturer support and availability.

Q: Are there differences in operating temperature ranges?

A: Yes. The 031-334 operates from -65°C to 165°C, while the 225974-2 operates from -55°C to 85°C. The 031-334 provides extended thermal capability. For applications within the 225974-2 temperature range, both connectors are functionally equivalent.

Q: Does the 031-334 support the same cable types as the 225974-2?

A: The 031-334 supports RG-55, 142, 223, and 400 cable groups. The 225974-2 supports RG-55, 55A, 55B, and 223. Both connectors are compatible with RG-55 and RG-223 cables. The 031-334 provides additional cable compatibility with RG-142 and RG-400.

Q: What are the compliance differences between these connectors?

A: The 031-334 is ROHS3 compliant and REACH affected. The 225974-2 is RoHS non-compliant with vendor-undefined REACH status. For applications subject to environmental regulations, the 031-334 is the appropriate selection.

Q: Are the termination methods identical?

A: The 225974-2 uses crimp termination only. The 031-334 supports both crimp and solder termination. For crimp applications, both connectors are equivalent. The 031-334 offers additional flexibility for solder termination if required.

Q: What is the packaging difference?

A: The 225974-2 packaging is not specified. The 031-334 is supplied in bulk packaging. Confirm packaging requirements with the supplier for your specific application needs.

Q: Are the center contact materials identical?

A: The 225974-2 uses brass center contact material. The 031-334 offers both brass and phosphor bronze options. For direct equivalence, specify the brass version of the 031-334.

Q: Do both connectors have the same mating cycle rating?

A: Yes. Both the 225974-2 and 031-334 are rated for 500 mating cycles.

Q: Is the insertion loss specification the same?

A: Yes. Both connectors have an insertion loss specification of 0.2 dB.
