• Identical connector type (Jack, Female Socket)
• Identical impedance rating (50 Ohms)
• Identical maximum frequency specification (18 GHz)
• Identical contact termination method (Solder)
• Identical shield termination method (Solder)
• Identical center contact material (Beryllium Copper)
• Identical center contact plating (Gold)

Mechanical Equivalence:

• Identical mounting type (Panel Mount)
• Identical mounting feature (Flange)
• Identical fastening type (Threaded)
• Identical number of ports (1)
• Identical housing color (Silver)

Regulatory Equivalence:

• Identical ECCN classification (EAR99)
• Identical HTSUS code (8536.69.4010)

The substitute part is manufactured by Huber+Suhner, Inc., an established RF connector manufacturer, and maintains Active product status with 836 units in stock.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0732510421 and Huber+Suhner 23_SMA-50-0-272/133_NH maintain Active product status and are suitable for direct substitution in applications requiring SMA female jack connectors with 50 Ohm impedance and 18 GHz maximum frequency operation.

The Molex part features stainless steel body construction with unspecified body finish. The Huber+Suhner substitute features brass body construction with white bronze finish and provides additional specification data including operating temperature range (-65°C ~ 165°C) and mating cycle rating (500 cycles). The Huber+Suhner part also carries ROHS3 compliance and REACH unaffected status certifications.

Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.69.4010) codes, confirming regulatory equivalence for export and tariff purposes.

Selection between these parts should be based on availability, procurement lead time, and any design-specific requirements regarding body material composition or documented operating temperature and mating cycle specifications.

Frequently Asked Questions (FAQ)

Q: Can the Huber+Suhner 23_SMA-50-0-272/133_NH be used as a direct replacement for the Molex 0732510421?

A: Yes. Both connectors share identical electrical specifications (SMA style, 50 Ohm impedance, 18 GHz maximum frequency), identical mechanical configuration (panel mount flange, threaded fastening, solder termination), and identical contact materials (beryllium copper with gold plating). The parts are electrically and mechanically interchangeable.

Q: What are the key differences between these two parts?

A: The primary differences are body material composition (Molex uses stainless steel; Huber+Suhner uses brass with white bronze finish) and documented performance specifications. The Huber+Suhner part provides explicit operating temperature range (-65°C ~ 165°C) and mating cycle rating (500 cycles), while the Molex part does not specify these parameters. Both parts maintain identical RF performance characteristics and regulatory classifications.

Q: Are there any compliance or certification differences?

A: The Huber+Suhner part carries ROHS3 compliance and REACH unaffected status certifications. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. The Molex part specifies MSL 1 (Unlimited), while the Huber+Suhner part lists MSL as Not Applicable.

Q: What is the impedance rating, and why is it important?

A: Both connectors are rated for 50 Ohm impedance, the standard impedance for RF and microwave applications. This specification ensures proper signal transmission and minimal reflections when mated with 50 Ohm coaxial cables and RF equipment.

Q: What is the maximum frequency these connectors support?

A: Both the Molex 0732510421 and Huber+Suhner 23_SMA-50-0-272/133_NH support operation up to 18 GHz, making them suitable for high-frequency RF applications including microwave and millimeter-wave systems.

Q: What termination methods are used?

A: Both connectors use solder termination for both the center contact and shield. This method provides permanent mechanical and electrical connection to PCB traces or cable assemblies.

Q: What is the mounting configuration?

A: Both connectors are panel mount with flange mounting feature and threaded fastening. The flange provides mechanical stability and the threaded design allows secure mating with standard SMA male connectors.

Q: Are these connectors suitable for high-temperature applications?

A: The Huber+Suhner part specifies an operating temperature range of -65°C to 165°C. The Molex part does not provide explicit operating temperature specifications in the available data. For applications requiring confirmed high-temperature performance, the Huber+Suhner part provides documented thermal specifications.
