Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 73029 is determined by the following critical parameters:

• Connector style must be MMCX
• Connector type must be jack with female socket configuration
• Impedance must be 50 ohms
• Mounting type must be free hanging (in-line)
• Contact termination must support solder or crimp methods
• Frequency rating must meet or exceed 4 GHz operational requirements
• Voltage rating must be at least 170 V
• Operating temperature range must encompass -55°C to 155°C
• Mating cycle rating must be 500 or greater

The Amphenol RF 262118 meets all substitution criteria as an active product with enhanced frequency capability and compatible cable group support.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 262118 is the direct functional equivalent for the obsolete Pomona Electronics 73029. Both connectors maintain identical electrical specifications including 50-ohm impedance, 170 V voltage rating, and 500 mating cycles. The 262118 provides superior frequency performance at 6 GHz compared to the 73029's 4 GHz maximum, ensuring compatibility with current and future RF applications.

The 262118 holds active product status with full ROHS3 compliance and EAR99 export classification, matching the regulatory profile of the original component. The primary termination difference—solder-only versus crimp-or-solder—reflects modern manufacturing practices while maintaining mechanical and electrical compatibility through identical snap-on fastening and gold-plated brass construction.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 262118 directly replace the Pomona 73029 in existing assemblies?

A: Yes. Both connectors share identical MMCX jack configuration, 50-ohm impedance, free-hanging mounting, snap-on fastening, and gold-plated brass construction. The 262118's solder termination is compatible with applications previously using the 73029's solder option.

Q: What is the significance of the frequency rating difference between 4 GHz and 6 GHz?

A: The 262118's 6 GHz maximum frequency exceeds the 73029's 4 GHz specification. This provides additional operational margin and compatibility with higher-frequency RF systems. Applications limited to 4 GHz or below operate safely within both components' specifications.

Q: Are there cable compatibility differences between these connectors?

A: The 262118 supports an expanded cable group including RG-174, 188, 188A, 316, LMR-100, and M17/119-RG174, compared to the 73029's RG-174 and 316 support. This expanded compatibility does not restrict use with the original cable types.

Q: What are the packaging differences?

A: The 73029 includes 4 pieces per connector assembly (connector, contact, ferrule, heat shrink), while the 262118 includes 3 pieces (connector, contact, ferrule). Both provide complete functional assemblies for cable termination.

Q: Do both connectors meet current regulatory requirements?

A: Yes. Both the 73029 and 262118 are ROHS3 compliant with EAR99 export classification. The 262118's active product status ensures ongoing compliance support and availability.
