Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1-225661-3 is determined by strict alignment across the following critical parameters: connector style, connector type (plug with male pin), contact termination method, impedance rating, mounting configuration, frequency capability, and fastening mechanism.

Direct Equivalent (Same Connector Style): The Amphenol RF 82-5370 qualifies as a direct equivalent substitute. Both parts maintain N Type connector style, male pin plug configuration, 50 Ohms impedance, free hanging in-line mounting, threaded fastening, and 11 GHz maximum frequency operation. The 82-5370 accepts both crimp and solder termination methods, providing termination flexibility while maintaining crimp compatibility with the original specification.

Similar Connector (Different Connector Style): The Amphenol RF 082-4450 is classified as a similar connector rather than a direct equivalent. While it shares 50 Ohms impedance, free hanging in-line mounting, threaded fastening, 11 GHz frequency capability, and identical operating temperature range, it employs SC connector style rather than N Type. This fundamental difference in connector geometry and mating interface prevents direct substitution without mechanical redesign of mating components.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (N Type Connector Required): The Amphenol RF 82-5370 is the appropriate selection when N Type connector geometry is mandated by system design. This part is currently in active production status, ensuring long-term availability and supply chain stability. The 82-5370 achieves ROHS3 compliance, addressing regulatory requirements that the obsolete 1-225661-3 does not meet. The elevated voltage rating of 1500 V provides additional safety margin compared to the original 1000 V specification. Termination flexibility (crimp or solder) accommodates various assembly methodologies while maintaining full crimp compatibility with the original specification.

For System Redesign Scenarios (Connector Style Flexibility): The Amphenol RF 082-4450 applies only when system architecture permits SC connector substitution. This part is active and ROHS3 compliant. The SC connector style requires mechanical redesign of mating interfaces and is not interchangeable with N Type connectors without system-level modifications. Selection of this part is contingent upon complete system compatibility assessment.

Compliance Considerations: Both active substitute parts achieve ROHS3 compliance, addressing environmental and regulatory requirements. The original 1-225661-3 is classified as RoHS non-compliant, making transition to compliant alternatives necessary for new designs and long-term procurement strategies.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 82-5370 directly replace the TE Connectivity 1-225661-3 without system modifications?

A: Yes, the 82-5370 provides direct replacement capability. Both parts maintain identical N Type connector style, male pin configuration, 50 Ohms impedance, free hanging in-line mounting, and 11 GHz frequency operation. The 82-5370 accepts crimp termination, matching the original specification, and additionally supports solder termination for assembly flexibility.

Q: What is the significance of the voltage rating difference between the 1-225661-3 (1000 V) and the 82-5370 (1500 V)?

A: The 82-5370 provides a 50% higher voltage rating, offering increased safety margin and broader application compatibility. Systems designed for 1000 V operation function within the 82-5370 specification envelope. The higher rating does not introduce incompatibility; it expands the part's operational range.

Q: Why is the Amphenol RF 082-4450 listed as a similar connector rather than a direct equivalent?

A: The 082-4450 employs SC connector style geometry, whereas the original part and direct equivalent use N Type connectors. Connector style determines physical mating interface and mechanical compatibility. SC and N Type connectors are not interchangeable without redesigning mating components and system architecture. The 082-4450 is suitable only for applications where connector style flexibility exists.

Q: What cable groups are compatible with each substitute part?

A: The 1-225661-3 supports RG-55A and RG-223 cable groups. The 82-5370 (direct equivalent) supports RG-55, RG-142, RG-223, and RG-400, providing broader cable compatibility. The 082-4450 supports RG-8, RG-8A, RG-9, RG-9A, RG-9B, RG-87, RG-213, RG-214, RG-225, RG-302, and RG-393, reflecting its SC connector design.

Q: Are there packaging differences between the original part and substitutes?

A: The original 1-225661-3 packaging specification is not provided. The 82-5370 and 082-4450 are supplied in bulk packaging. Packaging configuration should be confirmed with procurement specifications for your application.

Q: What is the insertion loss specification for the substitute parts?

A: The original 1-225661-3 insertion loss is not specified. The 82-5370 (direct equivalent) specifies 0.15 dB insertion loss. The 082-4450 (similar connector) also specifies 0.15 dB insertion loss. Both substitute parts provide documented insertion loss performance.

Q: How do the RoHS compliance statuses affect part selection?

A: The original 1-225661-3 is RoHS non-compliant. Both substitute parts (82-5370 and 082-4450) achieve ROHS3 compliance. For new designs, regulatory requirements, or procurement policies mandating RoHS compliance, the active substitute parts are necessary. Existing systems using the obsolete part may continue operation, but long-term procurement strategy should transition to compliant alternatives.

Q: Are the mating cycle ratings identical across all parts?

A: Yes, all three parts specify 500 mating cycles, indicating equivalent mechanical durability and connector longevity under normal operating conditions.
