Parameter Comparison

Engineering Selection Recommendations

Both the RFN-1027 and 082-5376-RFX are Active products with full ROHS3 compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4010). Selection between these components should be based on the following criteria:

RFN-1027 (RF Industries): Select when the primary requirement is a standard N Type female jack crimp connector with 50 Ohm impedance and 11 GHz frequency capability. This part meets baseline electrical and mechanical specifications for general RF applications.

082-5376-RFX (Amphenol RF): Select when enhanced performance characteristics are required or when cable group compatibility with RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, or 9907 is specified. This part provides superior insertion loss (0.15 dB vs. 0.2 dB), higher voltage rating (1500 V vs. 1000 V), documented mating cycle rating (500 cycles), and operating temperature range (-65°C to 165°C). The 082-5376-RFX also offers dual termination capability (Crimp or Solder) and includes component kit (1 Connector, 1 Contact, 1 Ferrule).

Both parts maintain identical core RF performance at 11 GHz maximum frequency and 50 Ohm impedance with PTFE dielectric and gold-plated center contacts.

Frequently Asked Questions (FAQ)

Q: What are the primary electrical parameters that determine substitution compatibility between RFN-1027 and 082-5376-RFX?

A: The critical electrical parameters are connector style (N Type), connector type (Jack, Female Socket), impedance (50 Ohms), frequency rating (11 GHz maximum), and dielectric material (PTFE). Both parts meet these specifications identically.

Q: Can the 082-5376-RFX be used as a direct replacement for RFN-1027 in existing designs?

A: Yes. The 082-5376-RFX maintains identical mechanical mounting (free hanging, in-line, threaded fastening) and electrical specifications (50 Ohms, 11 GHz, PTFE dielectric, gold-plated center contact). The substitute part offers enhanced performance with lower insertion loss and higher voltage rating.

Q: What is the difference in contact termination between these two parts?

A: The RFN-1027 specifies crimp termination only. The 082-5376-RFX offers dual termination capability (Crimp or Solder), providing greater flexibility in assembly methods while maintaining crimp compatibility with the original part.

Q: Are there cable compatibility considerations when selecting between these connectors?

A: The 082-5376-RFX includes documented cable group compatibility with RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. The RFN-1027 does not specify cable group compatibility in the provided parameters. If cable group compatibility is a design requirement, the 082-5376-RFX provides this specification.

Q: What packaging differences exist between these parts?

A: The RFN-1027 is supplied in standard packaging with 1071 pieces in stock. The 082-5376-RFX is supplied in Bulk packaging and includes a component kit (1 Connector, 1 Contact, 1 Ferrule) with 12800 pieces in stock.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 Compliant, classified as EAR99 for export control, and assigned the same HTSUS code (8536.69.4010). Both maintain Moisture Sensitivity Level 1 (Unlimited). The 082-5376-RFX additionally carries REACH Affected status.

Q: What is the performance difference in insertion loss between these connectors?

A: The RFN-1027 specifies 0.2 dB insertion loss. The 082-5376-RFX specifies 0.15 dB insertion loss, representing a 25% reduction in signal loss at the connector interface.

Q: Is the operating temperature range a factor in selecting between these parts?

A: The RFN-1027 does not specify an operating temperature range in the provided parameters. The 082-5376-RFX specifies -65°C to 165°C operating temperature range. If extended temperature operation is required, the 082-5376-RFX provides this specification.
