Substitute Part Grouping Explanation

The Cinch Connectivity Solutions Johnson part number 133-3402-101 qualifies as a direct substitute based on the following critical parameters:

Matching Core Specifications:

• Connector style: MCX (identical mechanical interface)
• Connector type: Plug, Male Pin (same gender and pin configuration)
• Impedance: 50 Ohms (electrical compatibility maintained)
• Mounting type: Free Hanging (In-Line), Right Angle (identical form factor)
• Contact termination: Solder (same assembly method)
• Shield termination: Crimp (same shielding approach)
• Fastening type: Snap-On (compatible mating mechanism)
• Dielectric material: PTFE (same insulation material)
• Body material and finish: Brass with Gold plating (equivalent construction)
• Center contact material and plating: Brass with Gold (equivalent contact properties)

Enhanced Performance Characteristics: The substitute part 133-3402-101 exceeds the original specification in several parameters: maximum frequency of 6 GHz (versus 3 GHz), operating temperature range of -65°C to 165°C (versus -55°C to 155°C), and voltage rating of 250 V (versus 170 V). These enhancements provide superior performance margins without compromising compatibility.

Cable Group Compatibility: The substitute supports RG-178 and RG-196 cable groups, with RG-178 being the primary specification shared with the original part.

Parameter Comparison

Engineering Selection Recommendations

The Cinch Connectivity Solutions Johnson 133-3402-101 is the qualified substitute for the obsolete Pomona Electronics 73006. Both parts maintain ROHS3 compliance and share identical export classification (EAR99) and tariff codes (HTSUS 8536.69.4010).

The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. The Cinch part is currently in stock with 1,486 units available, compared to the Pomona part's 767 units of remaining inventory.

For applications operating within the original Pomona 73006 specifications (3 GHz maximum frequency, -55°C to 155°C temperature range, 170 V voltage rating), the Cinch 133-3402-101 provides direct functional equivalence with enhanced performance margins. The higher frequency rating (6 GHz), extended temperature range (-65°C to 165°C), and increased voltage rating (250 V) do not introduce incompatibility and support broader application flexibility.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 133-3402-101 be used as a direct replacement for the Pomona 73006 in existing designs?

A: Yes. Both connectors share identical MCX plug configuration, 50-ohm impedance, right-angle solder mounting, and snap-on fastening. The mechanical and electrical interfaces are fully compatible.

Q: What is the significance of the higher frequency rating on the substitute part?

A: The Cinch part supports 6 GHz operation versus the Pomona part's 3 GHz maximum. This enhanced specification does not affect compatibility with systems designed for 3 GHz operation; it simply provides additional performance margin for future applications.

Q: Are there packaging differences between these parts?

A: The Pomona 73006 is supplied with packaging not specified in the available data. The Cinch 133-3402-101 is supplied in bulk packaging. Both include equivalent component sets: connector, end cap, ferrule or sleeve, and insulator.

Q: Do both parts support RG-178 cable applications?

A: Yes. The Pomona 73006 is rated for RG-178 cable group. The Cinch 133-3402-101 supports both RG-178 and RG-196 cable groups, with RG-178 compatibility confirmed.

Q: What is the compliance status of the substitute part?

A: The Cinch 133-3402-101 is ROHS3 compliant and REACH affected. The original Pomona 73006 is ROHS3 compliant and REACH unaffected. Both share EAR99 export classification.

Q: Are the mating cycle ratings identical?

A: Yes. Both the Pomona 73006 and Cinch 133-3402-101 are rated for 500 mating cycles.
