Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 82-312 are qualified based on the following core parameters that determine functional interchangeability:

Electrical Compatibility Parameters:

• Connector style (N Type)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Frequency maximum (11 GHz)
• Voltage rating (1500 V)
• Insertion loss (0.15 dB)
• Mating cycles (500)

Mechanical Compatibility Parameters:

• Contact termination (Solder)
• Shield termination (Clamp)
• Mounting type (Free Hanging/In-Line)
• Fastening type (Threaded)
• Cable group compatibility (RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, 393)

Material and Environmental Parameters:

• Body material (Brass)
• Body finish (Nickel)
• Dielectric material (PTFE)

Substitute parts 82-202 and 82-202-RFX maintain all core electrical and mechanical parameters. Variations in operating temperature range and center contact plating material do not affect functional substitution within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Amphenol RF 82-202

The 82-202 is a direct functional equivalent to the 82-312 across all core electrical and mechanical parameters. Both parts maintain identical impedance (50 Ohms), frequency response (11 GHz maximum), voltage rating (1500 V), and insertion loss (0.15 dB). The 82-202 offers an extended operating temperature range (-65°C to 165°C versus -55°C to 85°C) and achieves RoHS3 compliance. This part is suitable for applications requiring broader environmental operating conditions while maintaining full electrical compatibility.

Secondary Substitute: Amphenol RF 82-202-RFX

The 82-202-RFX provides identical electrical and mechanical specifications to the 82-312 with the addition of gold center contact plating instead of silver. This variant extends the operating temperature range to -65°C to 165°C and maintains RoHS compliance. The gold plating provides enhanced corrosion resistance and contact reliability in demanding environmental applications. Selection of this variant is appropriate when superior contact durability and extended temperature performance are required.

Compliance Considerations

All three parts (82-312, 82-202, and 82-202-RFX) are active production items with RoHS compliance certifications. The 82-202 achieves RoHS3 compliance, representing the most current regulatory standard. All parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 82-202 be used as a direct replacement for the 82-312 in existing designs?

A: Yes. The 82-202 maintains identical electrical specifications (50 Ohm impedance, 11 GHz frequency response, 1500 V rating, 0.15 dB insertion loss) and mechanical configuration (N Type plug, male pin, solder termination, threaded fastening). The extended operating temperature range (-65°C to 165°C) provides additional capability without affecting compatibility.

Q: What is the difference between the 82-202 and 82-202-RFX?

A: Both parts are electrically and mechanically identical. The primary difference is the center contact plating material: the 82-202 uses silver plating while the 82-202-RFX uses gold plating. Both maintain the same operating temperature range (-65°C to 165°C) and electrical performance. Gold plating offers enhanced corrosion resistance in harsh environments.

Q: Are all substitute parts compatible with the same cable types?

A: Yes. All three parts (82-312, 82-202, and 82-202-RFX) support the same cable group: RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393.

Q: What is the significance of the RoHS3 compliance on the 82-202?

A: RoHS3 compliance indicates adherence to the most current Restriction of Hazardous Substances directive. This certification is relevant for applications subject to current regulatory requirements. The 82-312 and 82-202-RFX maintain standard RoHS compliance, which is sufficient for most applications.

Q: Do the substitute parts include the same accessory components?

A: The 82-312 includes 8 pieces (1 Connector, 1 Braid Clamp, 1 Clamp, 1 Contact, 1 Gasket, 2 Insulators, 1 Washer). The 82-202 and 82-202-RFX include 6 pieces (1 Connector, 1 Braid Clamp, 1 Clamp, 1 Contact, 1 Gasket, 1 Washer). Verify accessory requirements for your specific application.

Q: What operating temperature range should I select?

A: The 82-312 operates from -55°C to 85°C. Both substitute parts (82-202 and 82-202-RFX) extend this range to -65°C to 165°C. Select the 82-202 or 82-202-RFX if your application requires operation outside the -55°C to 85°C envelope.

Q: Are there inventory considerations when selecting between these parts?

A: Current inventory levels are: 82-312 (1017 pcs), 82-202 (883 pcs), and 82-202-RFX (1841 pcs). The 82-202-RFX has the highest available stock.
