Molex 0733660000 MCX Connector Jack Equivalent & Substitute Parts

Part Overview

The Molex 0733660000 is an MCX connector jack, female socket rated for 50 ohms impedance, designed for through-hole PCB mounting with solder termination. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The connector operates across a frequency range up to 6 GHz with a mating cycle rating of 500 cycles and operates reliably across -55°C to 155°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0733660000 is determined by the following critical parameters:

• Connector Style: MCX (required match)
• Connector Type: Jack, Female Socket (required match)
• Impedance: 50 Ohms (required match)
• Mounting Type: Through Hole (required match)
• Contact Termination: Solder (required match)
• Shield Termination: Solder (required match)
• Frequency - Max: 6 GHz (required match or higher)
• Mating Cycles: 500 (required match or higher)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in housing color, body finish, and operating temperature ranges are permitted where the substitute maintains or exceeds the specified performance envelope.

Parameter Comparison

Engineering Selection Recommendations

Molex 0733660060 is the manufacturer-recommended direct replacement. This part maintains identical electrical and mechanical specifications to the original 0733660000 while offering active product status and improved availability. Both parts share the same base product number (073366) and are functionally equivalent for all applications.

Amphenol RF 919-109J-51PX is classified as a receptacle rather than a jack connector type. While it meets the core MCX 50-ohm through-hole solder termination requirements, the connector type designation differs from the original specification. This part is suitable only where receptacle-type MCX connectors are functionally compatible with the application.

Amphenol RF 919-NM109J-51P matches the jack connector type and all critical electrical parameters. This part includes a non-magnetic feature and operates across -40°C to 155°C, which covers the original operating range. The Amphenol RF part is suitable for applications where the non-magnetic characteristic provides additional design benefit or where the narrower lower temperature limit (-40°C versus -55°C) is acceptable.

All substitute parts carry ROHS3 compliance and are available in active production status, ensuring long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0733660060 be used as a direct replacement for the 0733660000?

A: Yes. The 0733660060 is the manufacturer-recommended equivalent and maintains identical specifications for connector style, type, impedance, mounting, termination, frequency range, and mating cycles. The primary difference is product status: the 0733660000 is obsolete while the 0733660060 is active production.

Q: What is the difference between the Amphenol RF 919-109J-51PX and the other substitutes?

A: The 919-109J-51PX is designated as a receptacle connector type, whereas the original Molex 0733660000 and the other substitutes are jack connectors. Both connector types are MCX female sockets rated for 50 ohms, but the receptacle designation indicates a different mechanical interface. Compatibility depends on the mating connector type in the application.

Q: Are there temperature range differences between the substitutes?

A: Yes. The Molex 0733660000 and 0733660060 operate from -55°C to 155°C. The Amphenol RF 919-109J-51PX extends the lower limit to -65°C and upper limit to 165°C. The Amphenol RF 919-NM109J-51P operates from -40°C to 155°C. For applications requiring the full -55°C lower limit, the Molex 0733660060 is the appropriate choice.

Q: What does the non-magnetic feature on the Amphenol RF 919-NM109J-51P mean?

A: The non-magnetic designation indicates that the connector body materials do not exhibit magnetic properties. This feature is relevant for applications where magnetic interference must be minimized or where the connector operates in magnetically sensitive environments.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the Molex 0733660060 and both Amphenol RF options, carry ROHS3 compliance certification.

Q: What packaging options are available for these substitutes?

A: The Molex 0733660060 is supplied in bag packaging. Both Amphenol RF parts (919-109J-51PX and 919-NM109J-51P) are supplied in bulk packaging. Packaging selection may affect procurement quantities and handling procedures.
