Substitute Part Grouping Explanation

Substitute parts for the 73033 are identified based on strict electrical and mechanical parameter alignment. The primary substitution criterion is functional equivalence across the following parameters:

Connector style (MMCX)
Connector type (Plug, Male Pin)
Impedance (50 Ohms)
Contact and shield termination method (Solder)
Mounting configuration (Free Hanging, Right Angle)
Frequency capability (6 GHz maximum)
Cable compatibility (RG-405 semi-rigid)
Operating temperature range (-55°C ~ 155°C)
Voltage rating (170 V)
Mating cycle rating (500)
Dielectric material (PTFE)
RoHS3 compliance

The Cinch Connectivity Solutions 135-3693-101 meets all these criteria and qualifies as a direct functional substitute.

Engineering Selection Recommendations

The Cinch Connectivity Solutions 135-3693-101 is the qualified substitute for the obsolete Pomona 73033. Selection is based on the following factors:

Product Status: The 73033 is obsolete, while the 135-3693-101 maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both parts maintain ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The 135-3693-101 carries REACH Affected status, indicating full compliance with REACH regulations.

Electrical and Mechanical Equivalence: All critical parameters—impedance, frequency response, termination method, mounting configuration, and operating specifications—are identical between the two parts.

Cable Compatibility: The 135-3693-101 supports both .085" and .086" RG-405 semi-rigid cable diameters, providing broader cable accommodation than the 73033.

Inventory Availability: The 135-3693-101 is available in significantly higher quantities (35,397 pcs), supporting both immediate requirements and long-term stock planning.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 135-3693-101 directly replace the Pomona 73033 in existing designs?

A: Yes. Both connectors share identical electrical specifications (50-ohm impedance, 6 GHz frequency capability, 170 V rating), mechanical mounting configuration (right-angle, free-hanging solder termination), and operating temperature range (-55°C to 155°C). The 135-3693-101 is a direct functional equivalent.

Q: What is the difference in center contact material between these parts?

A: The 73033 uses phosphor bronze, while the 135-3693-101 uses beryllium copper. Both materials provide equivalent electrical performance and durability for the specified 500 mating cycles.

Q: Are there packaging differences between the two parts?

A: The 73033 is supplied with three pieces per connector (connector, end cap, insulator). The 135-3693-101 is supplied with two pieces per connector (connector, end cap). Both configurations are suitable for solder termination applications.

Q: Does the 135-3693-101 support the same cable types as the 73033?

A: Yes. The 135-3693-101 accommodates RG-405 semi-rigid cable with both .085" and .086" diameters, providing compatibility with the .085" specification of the 73033 and additional flexibility for .086" cable applications.

Q: What is the insertion loss specification for the 135-3693-101?

A: The 135-3693-101 specifies 0.2 dB insertion loss. This specification is not provided for the 73033 but is typical for MMCX connectors in this class.

Q: Are both parts RoHS compliant?

A: Yes. Both the 73033 and 135-3693-101 are ROHS3 compliant. The 135-3693-101 additionally carries REACH Affected status, indicating full compliance with REACH chemical regulations.
