Key Parameters

Substitute Part Grouping Explanation

Substitution for the Pomona Electronics 73039 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector style: MMCX
• Connector type: Jack, female socket
• Impedance: 50 ohms
• Contact and shield termination: Solder
• Fastening type: Snap-on
• Voltage rating: 170 V
• Mating cycles: 500
• RoHS compliance: ROHS3 Compliant

Substitute parts are grouped into two categories based on mounting configuration:

Direct Substitutes (Through-Hole Mounting): Parts that maintain identical mounting type to the original component.

Functional Alternatives (Surface Mount Mounting): Parts that meet all electrical specifications but differ in mounting type, requiring PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Substitution:

Molex 0734151471 is the primary direct substitute. This part maintains through-hole mounting configuration and meets all electrical specifications. The part is active in production with higher frequency capability (6 GHz) and extended operating temperature range (-55°C to 165°C). ROHS3 compliance and REACH unaffected status align with the original component.

Cinch Connectivity Solutions 135-3701-211 provides an alternative through-hole option with identical operating temperature range to the original (-55°C to 155°C). This part is active in production and ROHS3 compliant. REACH affected status requires compliance verification for specific applications.

Cinch Connectivity Solutions 135-3701-201 offers extended operating temperature range (-65°C to 165°C) in through-hole configuration. This part is active in production and ROHS3 compliant. REACH affected status requires compliance verification for specific applications.

For Surface Mount Applications:

Amphenol RF 908-22116 is a functional alternative for designs requiring surface mount technology. This part meets all electrical specifications with 6 GHz frequency capability and extended operating temperature range (-65°C to 165°C). PCB layout modification is required due to surface mount mounting type. ROHS3 compliance and REACH affected status apply.

Frequently Asked Questions (FAQ)

Q: Can Molex 0734151471 be used as a direct replacement for Pomona 73039?

A: Yes. Both parts share identical connector style (MMCX), type (jack, female socket), impedance (50 ohms), termination method (solder), mounting type (through hole), fastening type (snap-on), voltage rating (170 V), and mating cycles (500). Both are ROHS3 compliant. The Molex part offers enhanced frequency capability (6 GHz vs 3 GHz) and extended temperature range.

Q: What is the difference between the Cinch 135-3701-201 and 135-3701-211 parts?

A: Both parts are MMCX jack connectors with identical electrical specifications and through-hole mounting. The primary difference is operating temperature range: 135-3701-201 operates from -65°C to 165°C, while 135-3701-211 operates from -55°C to 155°C. Selection depends on application temperature requirements.

Q: Why is Amphenol RF 908-22116 listed as a functional alternative rather than a direct substitute?

A: The Amphenol RF 908-22116 uses surface mount technology, whereas the original Pomona 73039 and primary substitutes use through-hole mounting. While all electrical parameters align (MMCX, 50 ohms, solder termination, 170 V, 500 mating cycles), the different mounting type requires PCB redesign and is not a pin-compatible replacement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts meet ROHS3 compliance requirements, matching the original Pomona 73039 specification.

Q: What is the significance of REACH affected status on some substitute parts?

A: Cinch Connectivity Solutions parts (135-3701-201 and 135-3701-211) and Amphenol RF 908-22116 are listed as REACH affected. This indicates these parts may contain substances of concern under REACH regulations. Compliance verification is required for applications subject to REACH requirements. Molex 0734151471 is REACH unaffected.

Q: Can I use the Amphenol RF 908-22116 in an existing through-hole PCB design?

A: No. The Amphenol RF 908-22116 requires surface mount PCB footprint and assembly process. Existing through-hole designs require modification to accommodate this part. Through-hole substitutes (Molex 0734151471, Cinch 135-3701-201, or Cinch 135-3701-211) are recommended for direct PCB compatibility.
