Parameter Comparison

Engineering Selection Recommendations

Substitution Basis:

The TE Connectivity AMP Connectors 5225555-2 is a direct electrical and mechanical equivalent to the 225550-2. Both components share identical specifications across all critical RF performance parameters, including impedance, frequency rating, operating temperature range, and voltage rating. Both connectors employ crimp termination for contact and shield, support identical cable groups (RG-58A, RG-58C), and maintain weatherproof ingress protection with PTFE dielectric material.

Material Considerations:

The substitute part utilizes brass with nickel finish in place of phosphor bronze with silver finish. Both material combinations provide equivalent electrical conductivity and corrosion resistance suitable for RF connector applications. The nickel finish on the 5225555-2 provides equivalent environmental protection to the silver finish on the 225550-2 in standard operating conditions.

Compliance Status:

Both parts maintain RoHS compliance. The 225550-2 is ROHS3 compliant, while the 5225555-2 is RoHS compliant. Both are classified under ECCN EAR99 and share identical HTSUS coding (8536.69.4010), confirming regulatory equivalence for procurement and export purposes.

Availability and Lifecycle:

The 225550-2 is discontinued at DiGi Electronics. The 5225555-2 is listed as obsolete. Both parts are available through alternative distribution channels. The 5225555-2 provides specified mating cycle rating of 500 cycles, whereas the 225550-2 does not specify this parameter.

Frequently Asked Questions (FAQ)

Q: Can the 5225555-2 be used as a direct replacement for the 225550-2 in existing RF systems?

A: Yes. The 5225555-2 meets all electrical and mechanical specifications required for direct substitution. Both connectors are TNC male plug configurations with 50 ohm impedance, 11 GHz frequency rating, and identical termination methods. Cable compatibility (RG-58A, RG-58C) and operating temperature ranges are identical.

Q: Are there differences in the physical construction between these two parts?

A: The primary construction difference is body material and finish. The 225550-2 uses phosphor bronze with silver finish, while the 5225555-2 uses brass with nickel finish. Both material combinations provide equivalent electrical performance and environmental protection for RF connector applications. The external dimensions and mating interfaces remain identical.

Q: What is the significance of the mating cycle specification on the 5225555-2?

A: The 5225555-2 specifies 500 mating cycles, indicating the connector is rated for 500 connect/disconnect operations. The 225550-2 does not provide this specification. For applications requiring frequent mating cycles, the 5225555-2 provides documented performance data.

Q: Are both parts RoHS compliant?

A: Yes. The 225550-2 is ROHS3 compliant, and the 5225555-2 is RoHS compliant. Both meet regulatory requirements for hazardous substance restrictions. Both parts are classified as REACH Affected or Vendor Undefined, requiring verification of specific REACH compliance status with the supplier for applications in regulated markets.

Q: What cable types are compatible with these connectors?

A: Both the 225550-2 and 5225555-2 are compatible with RG-58A and RG-58C cable groups. These are standard 50 ohm coaxial cables commonly used in RF and microwave applications. Crimp termination is required for both connectors.

Q: Can these connectors be used in outdoor or harsh environment applications?

A: Yes. Both connectors are rated as weatherproof with operating temperature ranges from -65°C to 165°C. The weatherproof ingress protection and PTFE dielectric material support deployment in outdoor and temperature-variable environments. The nickel finish on the 5225555-2 and silver finish on the 225550-2 both provide corrosion resistance suitable for harsh conditions.

Q: What is the voltage rating for these connectors?

A: Both the 225550-2 and 5225555-2 are rated for 500 V. This voltage rating applies to the dielectric breakdown and insulation properties of the connector assembly.
