Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 73018 is determined by strict alignment with the following core parameters: MCX connector style, female socket receptacle type, 50-ohm impedance, surface-mount configuration, solder termination for both contact and shield, snap-on fastening, single port, brass body with gold finish, PTFE dielectric, and ROHS3 compliance.

The identified substitute parts maintain these critical electrical and mechanical specifications. Both substitute connectors operate at higher frequency maximums (6 GHz versus 3 GHz) and support extended operating temperature ranges (-65°C to 165°C versus -55°C to 155°C), representing enhanced performance envelopes compatible with the original application requirements. Voltage ratings and mating cycle specifications are either equivalent or superior across all candidates.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the electrical and mechanical requirements of the Pomona 73018. The TE Connectivity 1-1337582-0 carries active product status with ROHS3 compliance and REACH affected designation. The Cinch Connectivity Solutions 133-3711-201 also maintains active product status with ROHS3 compliance and REACH affected designation.

Selection between substitute options should be based on supply chain availability, procurement lead times, and established vendor relationships. Both parts demonstrate superior performance specifications relative to the original component, including doubled frequency capability and extended operating temperature ranges. The enhanced voltage ratings (335 V versus 170 V) provide additional design margin for RF applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1337582-0 or Cinch 133-3711-201 directly replace the Pomona 73018 in existing designs?

A: Yes. Both substitute parts maintain the critical MCX connector specifications, 50-ohm impedance, surface-mount configuration, solder termination, and snap-on fastening required for mechanical and electrical compatibility. The enhanced frequency and temperature specifications represent performance improvements over the original part.

Q: What is the difference between "Receptacle" and "Jack" terminology in the connector type field?

A: Both terms describe female socket connectors in MCX connector families. The functional electrical and mechanical characteristics remain equivalent for substitution purposes.

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

A: The Pomona 73018 packaging is not specified in the available data. The TE Connectivity 1-1337582-0 and Cinch 133-3711-201 are supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: What compliance certifications apply to these parts?

A: All three parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. The TE Connectivity and Cinch parts carry REACH affected designation, while the original Pomona part is REACH unaffected. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: How do the center contact materials differ between parts?

A: The Pomona 73018 uses beryllium copper, while the TE Connectivity 1-1337582-0 uses phosphor bronze and the Cinch 133-3711-201 uses beryllium copper. These material variations do not affect substitution eligibility for the specified electrical and mechanical parameters.
