Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5225555-2 is determined by strict alignment with the following critical parameters:

Electrical Compatibility Requirements:

• Connector style must be TNC
• Connector type must be Plug, Male Pin
• Impedance must be 50 Ohms
• Frequency maximum must be 11 GHz or greater
• Operating temperature range must encompass -65°C to 165°C
• Voltage rating must be 500 V or greater

Mechanical Compatibility Requirements:

• Contact termination must be Crimp
• Shield termination must be Crimp
• Mounting type must be Free Hanging (In-Line)
• Fastening type must be Threaded
• Mating cycles must be 500 or greater

Cable Compatibility:

• Must support RG-58A and/or 58C cable groups

Parts meeting all these criteria are classified as direct substitutes. The identified substitute parts are:

1. M39012/26B0015 (Amphenol SV Microwave) - Direct Manufacturer Equivalent
2. 225550-2 (TE Connectivity Aerospace, Defense and Marine) - Parametric Equivalent

Engineering Selection Recommendations

M39012/26B0015 (Amphenol SV Microwave) - Recommended Primary Substitute

This part is the preferred substitute for the obsolete 5225555-2. It maintains full electrical and mechanical compatibility across all critical parameters: TNC connector style, 50-ohm impedance, 11 GHz frequency capability, crimp termination for both center contact and shield, and identical operating temperature range. The part is currently in active production status with 1,189 units in stock. It carries ROHS3 compliance and REACH affected status, meeting current regulatory requirements. Cable group compatibility includes RG-58 and 303, which overlap with the original part's RG-58A and 58C specifications. The inclusion of heat shrink in the package differs from the original ferrule configuration but does not affect electrical performance.

225550-2 (TE Connectivity Aerospace, Defense and Marine) - Secondary Substitute

This part provides parametric equivalence with identical electrical specifications and cable group compatibility (RG-58A, 58C). It maintains the same connector style, impedance, frequency rating, and operating temperature range. The part is manufactured by TE Connectivity, the original manufacturer of the 5225555-2, ensuring design consistency. However, the part is discontinued at DiGi Electronics, limiting procurement availability. It carries ROHS3 compliance and REACH affected status. Mating cycle specification is not provided for this part.

Compliance Considerations

Both substitute parts meet current RoHS3 compliance requirements, whereas the original 5225555-2 carries RoHS Compliant status. The M39012/26B0015 is REACH affected, and the 225550-2 is also REACH affected. Both parts carry EAR99 ECCN classification, consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can M39012/26B0015 be used as a direct replacement for 5225555-2 in all applications?

A: M39012/26B0015 meets all critical electrical and mechanical parameters required for substitution: TNC connector style, 50-ohm impedance, 11 GHz frequency capability, crimp termination, and identical operating temperature range. Cable group compatibility is maintained for RG-58 series cables. The part is suitable for direct replacement in applications where these specifications are required.

Q: What is the difference in cable group compatibility between the main part and M39012/26B0015?

A: The 5225555-2 supports RG-58A and 58C cable groups. The M39012/26B0015 supports RG-58 and 303 cable groups. RG-58 is compatible with RG-58A and 58C applications. Verify specific cable type requirements for your application to ensure compatibility.

Q: Why is 225550-2 listed as a secondary substitute if it is manufactured by TE Connectivity?

A: While 225550-2 is manufactured by TE Connectivity and provides parametric equivalence, it is discontinued at DiGi Electronics, limiting procurement availability. M39012/26B0015 is in active production with higher inventory levels, making it the more practical choice for ongoing procurement needs.

Q: Are there differences in the included components between these parts?

A: The 5225555-2 includes 3 pieces: 1 connector, 1 contact, and 1 ferrule. The M39012/26B0015 includes 2 pieces: 1 connector and 1 heat shrink. The 225550-2 includes 3 pieces: 1 connector, 1 contact, and 1 ferrule. These packaging differences do not affect electrical performance or connector functionality.

Q: What is the significance of the product status classifications?

A: The 5225555-2 is classified as obsolete, indicating it is no longer manufactured. M39012/26B0015 is in active production, ensuring continued availability. The 225550-2 is discontinued at DiGi Electronics, indicating limited procurement channels. For new designs and ongoing procurement, M39012/26B0015 is the appropriate selection.

Q: Do all three parts meet current regulatory compliance standards?

A: The 5225555-2 carries RoHS Compliant status. Both M39012/26B0015 and 225550-2 carry ROHS3 Compliant status, representing current regulatory standards. All three parts carry EAR99 ECCN classification. M39012/26B0015 is REACH affected; 225550-2 is REACH affected. Verify compliance requirements for your specific application and region.

Q: What are the mating cycle specifications for these connectors?

A: The 5225555-2 specifies 500 mating cycles. The M39012/26B0015 specifies 500 mating cycles. The 225550-2 does not provide a mating cycle specification. For applications requiring specific mating cycle performance, M39012/26B0015 provides documented equivalence.
